SIXTY YEARS OF FUSION FUN
Fusion sector says now is time for firms to join supply chain
21 October 2022
The Fusion22 conference in the UK was told that there is a huge potential fusion industry and businesses were urged to get involved in the supply chain now.

At a session entitled How will fusion make the transition to an industry? at the event held in the Science Museum in London, there was talk of 10,000 or more fusion power plants being required in the future.
Ross Morgan, from Tokamak Energy, said that his company, and others, were designing and aiming to build prototype plants in the 2020s, with pilot plant demonstrations in the early 2030s and using that as a platform to deploy commerical fusion within that decade.
Asked when he thought the supply chain needed to develop to support fusion, he said: "I think from our perspective it needs to start now ... we want to to engage with partners and suppliers who are going to work with us through that journey and help deliver commercial fusion power plants in the future."
Heike Freund, chief operating officer of Marvel Fusion, cited Bloomberg's asessment of the fusion industry potentially being as big as USD40 trillion and also said that in her view the two dominating topics for the next decade would be artifical intelligence in software and fusion in hardware. "We need to build this industry but I'm convinced that people will want to go into this industry, especially the younger generation - people want to work on topics that have impact, they want to work on purposeful topics" such as fusion energy tackling climate change.
She added that the development of prototype fusion plants being developed now is "an amazing opportunity for suppliers ... if you are already involved in those prototype stages you have a good chance of also being the go-to partner for the later steps to come, so I think now is really the moment in time when companies should get engaged."
Greg Willetts, vice president for Technology & Cyber Solutions within Jacobs' Energy, Security and Technology business, said his company was committed to energy transition and said, with its project management, technical solutions and engineering experience, the aim was to help make the fusion industry real.
He said that as an industry there was the "opportunity to design a new industry and make it how we want to ... a golden opportunity to make it more diverse, more inclusive, more rooted in social value into the community, we can design that in by the way thiongs are procured".
The aim of the conference was to bring together the whole fusion sector to demonstrate the sector’s potential, and was organisated by the UK Atomic Energy Agency's Fusion Cluster and came alongside a number of announcements, including Canada’s General Fusion and the UKAEA agreeing to collaborate on projects to "advance the commercialisation of magnetised target fusion energy", including 'honing' General Fusion’s demonstration machine being built at Culham, near Oxford.
Earlier this month the UKAEA announced that its newly completed GBP10 million (USD11.4 million) extension has doubled the size of its Materials Research Facility (MRF) at Culham. Specialist materials that can withstand extreme conditions are a critical part of delivering fusion energy as a safe, sustainable, low-carbon energy supply, the UKAEA said. They are also essential in the development of STEP (Spherical Tokamak for Energy Production), the UK's prototype fusion power plant. The investment has seen an additional 12 shielded research rooms, used to hold high-end analytical instrumentation, added to the facility, as well as extensive new active chemical laboratory space, for scientists and engineers to develop more neutron-tolerant materials.
The UK also recently announced the selection of a site at West Burton in Nottinghamshire to host the STEP demonstration plant, which is due to begin operating by 2040. And last week the UKAEA and Tokamak Energy signed a five-year framework agreement for closer collaboration "on developing spherical tokamaks as a route to commercial fusion energy".
General Fusion and UKAEA outline further fusion collaboration

The projects will help "hone" the design of General Fusion’s demonstration machine being built at the UK’s "fusion cluster" at Culham, near Oxford.
Greg Twinney, CEO of General Fusion, said: "The leading-edge fusion researchers at UKAEA have proven experience building, commissioning, and successfully operating large fusion machines. Partnering with UKAEA’s incredible team will fast-track work to advance our technology and achieve our mission of delivering affordable commercial fusion power to the world."
Ian Chapman, CEO of UKAEA, said: "Fusion energy is one of the greatest scientific and engineering quests of our time. This collaboration will enable General Fusion to benefit from the ground-breaking research being done in the UK and supports our shared aims of making fusion part of the world’s future energy mix for generations to come."
Since its founding in 2002, General Fusion has formed more than 200,000 hydrogen plasmas. In its collaboration with the UKAEA the company will "harness UKAEA’s extensive neutron modelling software and expertise to simulate the neutron flux distribution from General Fusion’s operational large-scale plasma injector as well as future machines".
General Fusion is based in Vancouver, Canada, with locations in Oak Ridge, Tennessee in the USA and in London in the UK. In announcing the collaboration it said it benefits from the UKAEA’s expertise in building polychromators, used to measure electron temperature. "The UKAEA will be building a new, larger Thomson Scattering system which will be installed on General Fusion’s fusion demonstration machine at Culham," it added.
The UKAEA carries out fusion energy research on behalf of the UK government, overseeing the country’s fusion programme, including the MAST Upgrade (Mega Amp Spherical Tokamak) experiment as well as hosting the JET - Joint European Tourus - at Culham, which is operated for scientists from around Europe.
General Fusion's Magnetised Target Fusion approach involves injecting hydrogen plasma into a liquid metal sphere, where it is compressed and heated so that fusion occurs. The heat from the fusion of the hydrogen atoms is transferred into the liquid metal. This is different to the tokamak approach, which is used in JET and MAST Upgrade, but General Fusion and UKAEA said, when they announced last year that General Fusion was going to build its demonstration plant at Culham, that they intend to collaborate on a range of fusion energy technologies for power plant design and operation.
General Fusion says its approach to fusion "maximises the reapplication of existing industrialised technologies, bypassing the need for expensive superconducting magnets, significant new materials, or high-power lasers".
The announcement coincided with the first day of Fusion22, a conference for the industry organised by the UKAEA in London, which is focusing on the steps needed to develop a fusion industry, with the UK seeking to build on its established fusion research and resources and help make fusion energy a reality within the next few years.
Earlier this month the UKAEA announced that its newly completed GBP10 million (USD11.4 million) extension has doubled the size of its Materials Research Facility (MRF) at Culham. Specialist materials that can withstand extreme conditions are a critical part of delivering fusion energy as a safe, sustainable, low carbon energy supply, the UKAEA said. They are also essential in the development of STEP (Spherical Tokamak for Energy Production), the UK's prototype fusion power plant. The investment has seen an additional 12 shielded research rooms, used to hold high-end analytical instrumentation, added to the facility, as well as extensive new active chemical laboratory space, for scientists and engineers to develop more neutron-tolerant materials.

Defuelling completed at Japan's Monju reactor
21 October 202
All the fuel assemblies at the Monju prototype fast breeder reactor (FBR), which is being decommissioned, have now been transferred to a water-filled storage facility, the Japan Atomic Energy Agency (JAEA) has announced.

When decommissioning of the reactor began in 2018, 160 fuel assemblies were being stored within a sodium-filled storage tank, while 370 fuel assemblies remained within Monju's sodium-filled core. JAEA began by removing the assemblies from the sodium-filled tank into the water-filled pond, then transferring assemblies from the core into the sodium-filled tank prior to being moved to the storage pond.
JAEA has now announced that the final fuel assembly was removed from the sodium-filled tank and placed in the water-filled pond on 13 October.
"As a result, fuel assembly removal, which is the main work in the first phase of the decommissioning plan, all work (530 assemblies) has been completed," it said.
"The used fuel will be transferred to domestic and foreign operators with licenses for reprocessing in Japan or in countries with which Japan has signed agreements for cooperation on the peaceful uses of nuclear energy," according to JAEA.
JAEA submitted a detailed plan to decommission Monju, in line with the government's basic policy, to the Nuclear Regulation Authority (NRA) in December 2017. The plan comprises four stages. In the initial stage, JAEA will transfer all fuel to an on-site storage pool by fiscal 2022. In the second and third stages, the liquid sodium coolant will be extracted from Monju and related equipment will be dismantled. The reactor building will be demolished and removed by fiscal 2047 in the final stage. The NRA approved that plan in March 2018.
A key part of Japan's nuclear energy programme, the 280 MWe Monju FBR in Tsuruga City, Fukui Prefecture, initially started in 1994. However, it was shut down after just four months when about 700 kilograms of liquid sodium leaked from the secondary cooling loop. Although there were no injuries and no radioactivity escaped plant buildings, the operator tried to conceal the scale of the damage. It eventually restarted in May 2010 but has not operated since refuelling equipment fell into the reactor vessel during a refuelling outage later that year. The equipment was subsequently retrieved and replaced but the NRA did not permit the reactor to restart.
In November 2015, following concerns over equipment inspections, the NRA determined JAEA was not competent to operate the reactor. In December 2016, the government formally announced its decision to decommission the idled Monju reactor.
The decommissioning of Monju will take 30 years and cost more than JPY375 billion (USD2.5 billion), the government estimates. This includes JPY225 billion for maintenance, JPY135 billion for dismantling the plant and JPY15 billion for defuelling and preparations for decommissioning.
Two sites added to Rolls-Royce SMR's UK factory shortlist
21 October 2022
Rolls-Royce SMR is carrying out site visits of the eight locations now in the running to host its first factory for small modular reactors.

In July the company announced six potential locations for the factory, saying the shortlist was selected against a clear set of criteria, picked from more than 100 submissions from local enterprise partnerships and development agencies. They were: Sunderland in Tyne and Wear, Richmond in North Yorkshire, Deeside in Wales, Ferrybridge in Yorkshire, Stallingborough in Lincolnshire and Carlisle in Cumbria.
Two more locations - Shotton, Deeside, in North Wales and Teesworks, Redcar, in north east England - have now been added after the sites met the shortlist criteria for the first of three expected factories in the UK, which will produce the vessels for the 470 MWe pressurised water reactor.
Rolls-Royce SMR's chief operating officer David White is to oversee the construction of the factories which will be needed to construct the planned fleet of SMRs, each capable of generating the same amount of electricity as about 150 onshore wind turbines, and enough to power a million homes.
All the potential sites are to be visited over the next six weeks ahead of the next stage of the site-selection process.
White said: "The overwhelmingly positive response, resulting in more potential sites than we might have hoped for, means we have more information to assess but is vitally important in helping us select the right locations for our factory."
The Rolls-Royce SMR design was accepted for Generic Design Assessment review in March with the UK's Department for Business, Energy and Industrial Strategy asking the Office for Nuclear Regulation along with the environment regulators for England and Wales to begin the process.
To minimise the construction phase of the programme, the Rolls-Royce SMR is fully modularised with the reactor, about 16 metres by 4 metres, able to be transported by road, rail or sea. Targeting a 500-day modular build, the firm says this concept minimises the onsite time and effort required to construct and build the plant, with about 90% of manufacturing and assembly activities carried out in factory conditions.
Holtec, Hyundai to accelerate SMR development
20 October 2022
Holtec International of the USA and South Korea's Hyundai Engineering & Construction have agreed to accelerate the programme to complete the balance of plant design of the remaining systems and structures for the SMR-160 advanced small modular reactor.

The agreement was signed on 18 October by Holtec President and CEO Kris Singh and Hyundai E&C President and CEO Young-Joon Yoon at Holtec's Technology Campus in Camden, New Jersey.
The two companies - supported by Kiewit and Mitsubishi Electric - have been collaborating to develop a standard design, which will be deployable in most regions of the world without any significant modification, reducing the time from the customer's authorisation to proceed to the commissioning of the plant, Holtec said.
Hyundai E&C said it will participate in the detailed design necessary for the installation of the SMR-160 in consideration of the local natural environment and characteristics, such as climate, temperature, and humidity.
The new agreement builds on the teaming agreement signed in November 2021 under which Hyundai E&C will perform the detailed design of the balance of plant and prepare the full plant construction specification for the SMR-160, which Holtec has been developing since 2010. The Korean company will also develop the integrated 3D plant model for construction using its Building Information Modelling management process. The partnership also provides for project delivery rights for Hyundai, subject to certain provisions.
"The team recognises the urgent need to provide a clean energy eco-system that integrates the SMR-160 nuclear power plant with a competitive solar energy facility, and the clean energy storage and delivery system (called Green Boiler) being developed by Holtec to meet the needs of the post-fossil fuel economies of the world," Holtec said.
"Over the past year, Hyundai E&C and Holtec have fostered a solid partnership through close collaboration in design and engineering, working tirelessly to accelerate commercialisation and to solidify Team Holtec as the leader in the global clean energy marketplace," it added. "Joint efforts are being made to install SMR-160-centered ecosystems in over fifteen countries inclined to deploy SMR-160 and Green Boiler to meet their electricity and district heating needs."
Hyundai E&C has been developing the SMR-160 plant design construction specification through close association with Holtec, with the design and associated Safety Analysis Report underpinning a construction permit application to the US Nuclear Regulatory Commission (NRC) for the first SMR-160 plant in the USA.
Holtec is considering deploying the first SMR-160 at Oyster Creek in New Jersey, where it is currently in the process of decommissioning a former boiling water reactor.
Yoon said, "By accelerating completion of the SMR-160 development programme, we have further strengthened our cooperative relationship with Holtec, paving the way for a wide array of collaborations. As a power plant project developer, Hyundai E&C has taken a giant step toward becoming a total solution provider for clean energy at all stages - from business discovery, planning, and development, to construction, including future new technology development."
The SMR-160 is a pressurised light-water reactor, generating 160 MWe (525 MWt) using low-enriched uranium fuel, with flexibility to produce process heat for industrial applications and hydrogen production. The design has completed the first phase of the Canadian Nuclear Safety Commission's three-phase pre-licensing vendor design review, and is undergoing pre-licensing activities with the NRC.
Holtec said it aims to secure a US construction licence in 2025, and is "actively exploring the possibility" of deploying an SMR-160 at Oyster Creek - which it acquired from Exelon in 2019 following the plant's closure the previous year - and at two other sites in the southern USA.
In March this year, Holtec and Hyundai E&C agreed to cooperate in the area of nuclear plant decommissioning. As part of the agreement, Hyundai E&C will participate in decommissioning activities at Holtec-owned decommissioning sites in the USA to build their capabilities and experience in preparation for decommissioning projects in South Korea, which will be undertaken by the two companies. The agreement also provides for the two companies to further expand their cooperation internationally.
Holtec in July submitted an application for a USD7.4 billion federal loan to enable it to increase capacity for SMR production at its existing manufacturing facilities, to construct and operate four SMR-160s in the USA and to build a new Holtec Heavy Industries (HHI) complex for higher capacity manufacturing of components and modules for SMR-160s. It is still evaluating the location of HHI, but said the proposed mega-plant would likely be close to the site of its first US SMR-160.
Prime Minister Sheikh Hasina has hailed the benefits to come at an event coinciding with the installation of the reactor pressure vessel at Rooppur 2, the second unit of Bangladesh's first nuclear power plant.

The prime minister joined the event virtually, saying: "Rooppur NPP will help us provide a better life for our compatriots. Once again, I thank Russia for helping to build this power plant. We paid attention to the overall safety and reliability of the construction of a nuclear power plant. Safety was our main concern."
Rosatom Director General Alexey Likhachov, who is visiting Bangladesh, marked the occasion saying: "A year ago, we witnessed the installation of the first reactor vessel in its regular place, and today the same operation was completed at the second reactor. We see that the construction of the first nuclear power plant in Bangladesh is proceeding actively, despite the obstacles that the pandemic has created for us.
"I am sincerely grateful to the entire team of builders for their well-coordinated work. I express my gratitude to the authorities of the Republic of Bangladesh for their full support of the project. Together, every day we bring closer the launch of the nuclear power plant, which the people of Bangladesh are waiting for."
The Dhaka Tribune reports that during a visit to the construction site on Tuesday the Science and Technology minister Yeafesh Osman said the overall project was now 53% complete, and the first unit more than 70% complete.
The newspaper reported the Rooppur NPP Project Director Shaukat Akbar as saying they were hoping to meet the target of starting production of the first unit on a trial basis in October 2023 and "be fully ready to supply in 2024".
The Rooppur plant, which is about 160 kilometres from the capital Dhaka, will have two Russian VVER-1200 reactors with a capacity of 2400 MWe. As part of the installation process the 334-tonne reactor vessel was moved through the transport lock into the containment of the reactor building and installed in the design position.
During his visit, Likhachov also took part in the opening ceremony of the station's new training centre where staff from Bangladesh will be trained in specialised classrooms and production facilities.
Equipment being installed in ANSTO's Synroc radioactive waste processing facility
20 October 2022
The Australian Nuclear Science and Technology Organisation (ANSTO) says construction has been completed and processing equipment is now being installed in the Synroc facility which is due to begin operations in 2025.

The Synroc ("Synthetic Rock") facility will treat intermediate-level liquid radioactive waste from the production of nuclear medicine by immobilising the waste in a highly durable solid wasteform for final disposal. Synroc is an Australian innovation based on crystalline or mineral phases that have survived in natural geological environments at elevated temperatures in the presence of water for hundreds of millions of years.
In the Synroc process, the radioactive liquid waste is first mixed with additives that create a slurry that is then dried to produce a free-flowing powder. The granular powder is thermally treated before it is dispensed into cans where it is sealed. The can is then placed inside a furnace that is contained within a hot isostatic press (HIP), where heat and pressure are applied to lock in the radionuclides. Under these conditions the powdered mixture fuses together to form a solid without releasing any emissions. The can contracts to form a cylindrical shape which is designed for storage efficiency.
Although Australia does not have any nuclear power plants, it has a sizeable nuclear medicine industry with ANSTO producing 12,000 doses each week for patients, as well as exporting more.
ANSTO says there is growing international interest in the Synroc technology.
"Along with the benefits of a nuclear medicine production comes a responsibility to safely manage the by-product radioactive waste. That’s what our waste treatment technology has been designed to achieve," said ANSTO’s Synroc Technologies Technical Director Gerry Triani.
"Synroc is an innovative, safe and effective radioactive waste treatment technology which can be built into nuclear supply chains anywhere in the world," he added.
The building is now being fitted with the equipment for the Synroc process, "designed for remote operations inside a shielded hot-cell environment".
A full-scale demonstration Synroc plant has been operating for the past five years, showing, ANSTO says, that the technology offers a "safe and efficient means of treating their waste in a disposal ready product".
The start of regular electricity production at the Olkiluoto 3 EPR in Finland, currently scheduled for December, is likely to be delayed after damage was discovered in the internals of the feedwater pumps located in the plant's turbine island during maintenance and inspection work.

In the feedwater pumps, water from the feedwater tank is pumped into the steam generators. Operator Teollisuuden Voima Oyj (TVO) said the damage detected at the pumps has no impact on nuclear safety.
The company said the Areva-Siemens plant supplier consortium had informed it that the schedule impact of the feedwater pumps' damage is not yet known.
However, TVO said the damage will "most likely have an effect on the continuation of Olkiluoto 3's nuclear commissioning and the start of regular electricity production. A schedule estimate is to be completed during the upcoming days."
The Areva-Siemens consortium constructed the Olkiluoto 3 (OL3) plant under a fixed-price turnkey contract. They have joint liability for the contractual obligations until the end of the guarantee period of the unit. Construction of OL3 began in 2005, with completion of the reactor originally scheduled for 2009, but the project has had various delays and setbacks.
OL3 attained first criticality on 21 December last year and was connected to the grid on 12 March. The 1600 MWe pressurised water reactor is currently in an ongoing test production phase. It was operated at full capacity for the first time in late-September.
Efforts to create Zaporizhzhia safety zone continue amid fresh concerns
19 October 2022
International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi has reiterated the urgency of establishing a safety zone around the Zaporizhzhia nuclear power plant in Ukraine.

Grossi said that the nuclear plant had restored the connection to its last remaining 750 kilovolt power line on Tuesday 18 hours after its external power was lost for the third time in 10 days. Unlike the two previous occasions, when emergency diesel generators had to provide the backup power, this time the plant continued to receive electricity from an off-site 330kV backup line.
Although no fresh shelling was reported in the IAEA’s Tuesday update, it said that four landmines had exploded near the plant and work on restoring a second 330 kV backup line had been delayed by the shelling of infrastructure elsewhere in Ukraine.
The IAEA staff at the site also reported that the deputy director general of Zaporizhzhia nuclear power plant, Valeriy Martynyuk, had been released after more than a week. The previous director general of the plant had also been detained earlier this month before, in his case, being released into Ukraine-controlled territory.
Grossi welcomed the release of Martynyuk, but called it "another concerning development that I sincerely hope will be resolved swiftly".
Meanwhile, Ukraine’s nuclear power plant operator Energoatom said that two other senior staff - the head of IT services and the assistant general director - had been detained on Monday and Ukraine’s nuclear regulator SNRIU said the occupiers did not have "adequately trained and legitimate personnel" to manage the plant so were "trying to force Ukrainian specialists to enter into employment contracts".
In other developments on Wednesday, Russia’s Tass news agency reported that Russian forces had stopped an attempted landing of Ukrainian forces on more than 30 boats near Energodar, suggesting that they might have been planning to attempt to recapture the Zaporizhzhia plant, which has been under the control of the Russian military since early March.
With the nuclear power plant located on, or near, the front line of the war between Ukraine and Russia, Grossi said that recent events meant he believed "even more on the need to reach agreement" as soon as possible with the two sides on a safety and security zone at and around the plant.
In an interview with La Nacion newspaper during his current trip to Argentina, Grossi explained the process was "advancing" and said the two sides thought the idea of a safety zone was feasible and both had agreed to work with the IAEA. Asked if the accusations made by the two sides in the war complicated matters, he said he had to try to ignore that and instead his task was to “constantly keep my eyes on the goal that I have to achieve: which is to protect the plant".
Zaporizhzhia is Europe's largest nuclear power plant with six reactors. The Ukrainian plant has been under Russian military control since early March, but has continued to be operated by its Ukrainian staff. Parts of the plant, including some buildings close to the reactors, have been damaged during shelling at times during the conflict, which each side has blamed on the other. The nuclear power plant is within the part of Ukraine that Russia's president said his country was annexing two weeks ago, with a new Russian company created to run the nuclear plant. Ukraine has rejected Russia's annexation announcement, and insists it continues to operate and regulate the plant.
History-in-the-making for Canadian
uranium mining
18 October 2022
The recovery of uranium-bearing solution during the ongoing Phoenix in-situ leach (ISL) feasibility field test (FFT) is a historic moment for uranium mining in Canada, according to Denison Mines Corp.

The successful recovery of uranium-bearing solution means that injection of lixiviant - the leaching phase of the FFT - which began in September has now ended. Preparations are under way to transition to the neutralisation phase, which is expected to be completed before the end of the year. The final phase of the test - management of the recovered solution - is expected to start in the spring of 2023.
Denison President and CEO David Cates said the recovery of uranium-bearing solution "reflects the culmination of several years of technical de-risking and provides tangible validation" of the company's selection of ISL - sometimes referred to as in-situ recovery (ISR) - as the mining method for Phoenix following a 2018 pre-feasibility study for the entire Wheeler River project. "With this result, Denison has truly showcased its industry leadership in bringing the low-cost ISR mining method to the high-grade uranium deposits of the Athabasca Basin," he said.
Wheeler River, in northern Saskatchewan, is host to the high-grade Phoenix and Gryphon uranium deposits which were discovered by Denison in 2008 and 2014, respectively. The project includes combined indicated mineral resources of 132.1 million pounds U3O8 (50,812 tU) at an average grade of 3.3% U3O8, as well as combined inferred resources of 3.0 million pounds U3O8 at an average grade of 1.7% U3O8. The project is a joint venture between Denison and JCU (Canada) Exploration Company Limited (JCU), with Denison holding an effective 95% ownership interest (90% directly, and 5% indirectly through its 50% ownership of JCU).
The 2018 pre-feasibility study considered the potential economic merit of developing Phoenix as an ISL operation and Gryphon as a conventional underground mining operation. Taken together, the project is estimated to have mine production of 109.4 million pounds U3O8 over a 14-year mine life.
ISL recovers minerals from ore in the ground by dissolving them in situ. The solution is then pumped to the surface where the minerals can be recovered. This causes little surface disturbance and generates no tailings or waste rock, but requires suitable geology: the orebody needs to be permeable to the liquids used, and located so that groundwater away from the orebody cannot become contaminated. More than half of the world's uranium production is now produced by ISL, but the technique has not so far been used in Canada.
The FFT is using a commercial-scale ISL test pattern to enable a combined assessment of the hydraulic flow properties at the deposit and the leaching characteristics that have been assessed through a metallurgical core-leach testing programme. This will provide further verification of the parameters needed for the successful application of ISL at Phoenix, as well as validating and informing design elements including expected production and remediation profiles.
"The recovery of uranium-bearing solution at targeted rates and grades is history in the making," Kevin Himbeault, Denison's vice president of Plant Operations & Regulatory Affairs, said. "Initial analysis indicates the hydrogeological system has responded as expected with pH trends, flow characteristics and uranium recovery meeting expectations."
The next phase of the FFT - the neutralisation phase - will involve the recovery of the remainder of the leached mineralised solution and is intended to verify the efficiency and effectiveness of the process for returning the zone to environmentally acceptable conditions. During this phase, a mild alkaline solution will be injected into the leaching zone to neutralise the area and reverse the residual effects of the acidic solution injected during the leaching phase.

REPAIRING THE GREAT SCHISM WITH DUCKTAPE(C)
Vatican to host a debate at St. Peter’s in November between three Protestant, Orthodox and Catholic theologians
On November 22, the Vatican will host a debate in St. Peter's Basilica between a Catholic, a Protestant and an Orthodox theologian on the primacy of Peter, that is, on the primacy of the Bishop of Rome over all Christian confessions.
St. Peter's Square -
Cardinal Gianfranco Ravasi, president emeritus of the Pontifical Council for Culture, has been the main promoter of the discussions on the theme 'On this rock I will build my Church'. This theological debate is part of a new series of conferences on the figure of the Apostle Peter in history, art and culture that will take place in the basilica starting next Tuesday, October 25, and will conclude in March 2023.
One of the main knots of the ecumenical dialogue, that is, to achieve unity between Orthodox Christians, Protestants and the Catholic Church, has been the question of the primacy of Rome and the role of the Bishop of Rome. Ravasi stressed that the new cycle of conferences is not only for believers who want to find the reason for the hope that is in them, but also aims to reach out to non-Catholics.
As he pointed out in this regard, the Italian Baroque master Gian Lorenzo Bernini - who was the architect of St. Peter's Basilica - imagined the colonnade of the basilica as "two great arms that could embrace not only Catholics from all over the world, but also heretics or those of other faiths".
Ravasi founded the Courtyard of the Gentiles foundation within the Vatican's Dicastery for Culture and Education to promote dialogue between believers and non-believers through events, debates and research. This foundation is also one of the organizers of the new cycle of conferences together with the Fratelli Tutti Foundation, founded by Pope Francis in December 2021.
The two conferences planned for 2023 will focus on a "more cultural dimension" of the Apostle Peter, Ravasi explained. The Jan. 17 conference will look at the figure of St. Peter in history and culture, and the March 7 conference, titled 'Quo vadis,' will examine how Peter has been depicted in art, literature, music and film.
Deputies denounce pressure from the Unification Church to promote sect-friendly policies
Several Japanese deputies have denounced Friday that they have been pressured by groups affiliated with the Unification Church to push forward policies in line with the sect.

Two of these groups have allegedly tried to persuade the governmental Liberal Democratic Party (LDP) to promote policies in exchange for the support received by them in past elections.
Hideyuki Teshigawara, who heads the Unification Church, has admitted that one of its affiliated groups, the World Peace Federation, has tried to urge some deputies to sign documents that include related policies, according to reports by the Kiodo news agency.
Sources close to the matter have said that two organizations have reportedly contacted members of the formation nationwide and that some of the documents have been signed. At least three deputies have admitted receiving the documents in question.
The organization has been accused of forcing its followers to make large donations and its name has recently gained prominence after the assassination of former Prime Minister Shinzo Abe, whose self-confessed advisor, Tetsuya Yamagami, accused the sect of having bankrupted his family and Abe of having contributed to its establishment in the Asian country.
Despite these reports, the Japanese Prime Minister, Fumio Kishida, defended the objectivity of his party's deputies and pointed out that these cases have had no impact on the legislative process.
On Monday, Kishida himself promised to open an investigation against the Unification Church after the government received 1,700 telephone inquiries from followers complaining about its practices. In late July, several Japanese politicians admitted to links with the sect following the assassination of the former prime minister.
WHAT DO WE PAY TAXES FOR Regina anti-poverty advocates concerned about proposed switch to user-pay model for waste services
Laura Sciarpelletti - Yesterday - CBC
Anti-poverty advocates are worried that a proposed change to how Regina charges for waste pickup will hurt low-income households.
Regina's executive committee voted unanimously Wednesday in favour of charging on utility bills rather than property taxes for garbage, recycling and the new yard waste pickup program.
City councillors say this will allow residents to take waste management into their own hands. The matter goes to city council for a vote next week.
The user-pay option also includes a rate reduction component for low-income households with either a senior or person with a disability living there.
But anti-poverty activists say that isn't enough. They want more rebate options for other low-income Regina residents.
"This is happening at a time of extremely high inflation, a time when utility costs have been going up. It's post-implementation of the Saskatchewan Income Support (SIS) program, which has meant that for people on that program, their utilities are wrapped into their shelter allowance so they're not actually getting covered for the actual cost of their utilities," said Peter Gilmer, an advocate for the Regina Anti-Poverty Ministry.
Gilmer said his organization is seeing an increase in the number of people who are dealing with arrears and utility cut-offs. He said the switch to a user-pay model will negatively affect the people they work with the most.
Waste reduction
Regina's waste diversion rate has remained static at about 20 per cent since 2015. The city's goal is to increase it to 65 per cent to prolong the life of the city landfill.
Currently there is a mixed approach for funding waste services in Regina. Recycling service is paid for by a user fee charged on monthly utility bills, while garbage service is paid by property taxes.
If the user-pay system goes forward, the fee each resident pays would vary depending on the garbage cart size selected (240L or 360L) and eligibility for the affordability program.
"Ultimately we too are concerned about issues of long-term environmental and financial costs in terms of growing waste concerns, and we do realize that Regina has a high proportion of of waste," Gilmer said.
"But I don't believe that a user fee system is going to be the solution here. It certainly would not be equitable, but it would not be progressive and I think that it's going to add additional hardship for those many households that we're already dealing with that are finding themselves in utility arrear and cut-off situations."
Gilmer said he wants the city to look further at creative solutions for incentivizing waste reduction.
He said the Regina Anti-Poverty Ministry does not want the user-pay motion to pass when it goes to city council next week, but at the very least would like to see an amendment that expands rebate options.
However, Ward 8 Coun. Shanon Zachidniak said it would be administratively difficult to have two separate utility bill rebates for low-income households.
"I personally don't have the answer for what might be a logical amendment to expand the rebate to other low-income residents that doesn't cause challenges," Zachidniak said.
She said she understands how difficult paying the updated utility bills would be for many low-income people.
"I take that concern very seriously. I do feel like [administration] tried to carefully balance the needs of residents and the needs for us to reduce waste. I'm definitely open to hearing if there's another option not in the report that will accomplish both."
Administration's proposal includes an initial period where the garbage, recycling and yard waste services will be paid for by the city's utility reserve, according to Zachidniak.
"So residents will have the ability to adjust to this change and figure out what waste diversion, what size of cart meets their needs, and not have to pay extra for these services for four months next year," she said.
"So I do feel like they tried to carefully balance the needs of residents and the need for us to reduce waste."
Zachidniak said that as administration reports back annually, there will be continued opportunities for council to review and revise the program.
The standard garbage cart in Regina has a capacity of 360 litres,
The administration's affordability option is called the Waste Utility Rebate Program, and is for low-income households with seniors and/or people living with a disability.
It would apply a fixed rebate to participants' charge at the time of billing. The program will cost $100,000 per year, according to the city. This would be financed by user fees.
The standard daily rebate would be $0.15 per day ($54.75 per year). The increased daily rebate would be $0.30 ($109.50) for households that have an annual household income less than or equal to half of the eligibility threshold.
At Wednesday's meeting, administration recommended implementing the affordability option only if a full user-fee funding policy is adopted. If any other funding policy option is selected, then affordability would be factored into the tax portion.
Moving to a user fee for all three curbside waste services will remove approximately $8.9 million (or 3.16 per cent mill rate) in costs from the property tax base.
If approved by council, the new fee structure will come into effect Jan. 1, 2024.
GREEN CAPITALI$M THAT UNIONS LIKE
The Democrats' new climate and tax bill will invest billions in clean energy. Here are 21 high-paying green careers for people who want to save the planet.
There are many occupations out there that help the environment, such as wind turbine service technician.
The Inflation Reduction Act could mean more clean energy jobs created. Here are the 21 fastest-growing green jobs that also have an annual pay greater than the overall median pay.
Saving the earth and having a lucrative career aren't always mutually exclusive, and the Democrats' big climate and tax bill that just passed could mean even more investment in green jobs.
The Inflation Reduction Act could mean many more workers will be needed to fill various clean energy and other jobs in the coming years. The bill also says it will cut carbon emissions by about 40% by 2030.
"The Inflation Reduction Act builds a new clean energy manufacturing economy by investing in refurbishing old factories; building new factories; requiring high wages; and mandating apprenticeship training for companies using clean energy tax credits," The Center for American Progress wrote in a fact sheet. "The bill will spur domestic production of batteries, solar panels, wind turbines, and more, setting the United States up to compete in the global clean energy economy and creating millions of clean energy jobs."
AFL-CIO staff wrote that there will be "an especially big boost to manufacturing." According to Energy Innovation, 1.4 million to 1.5 million jobs in 2030 could be made as a result of the Inflation Reduction Act. According to research from the Political Economy Research Institute, there will be almost 1 million jobs created a year or more than 9 million over the decade as a result. Most of these millions of jobs created would come from grants, loans, and tax credits, according to BlueGreen Alliance who commissioned that analysis.
Per reporting from Axios, Philip Jordan, vice president of BW Research, said equipment installation and construction will see the biggest job gains.
"Green" jobs can lead to lofty incomes. For instance, construction managers typically make $98,890, according to median annual wage data for May 2021.
Additionally, projections from the Bureau of Labor Statistics show wind turbine service technician is the fastest-growing job in the country after "excluding occupations with above average cyclical recovery," according to projections from the Bureau of Labor Statistics (BLS). This occupation is estimated to grow by 68.2% between 2020 and 2030. Solar photovoltaic installers is also the third fastest-growing job — after excluding jobs with "above average cyclical recovery" — with projected employment growth of 52.1% from 2020 to 2030.
Insider looked at different green jobs that are projected to quickly grow and that pay well. To find the 21 fastest-growing green jobs that also pay well, we looked at employment projections from BLS for jobs that are considered green jobs on the Occupational Information Network (O*NET). We only included occupations that had median annual pay above the overall national median of $45,760 as reported by BLS for May 2021.
A Bill Gates fund invested $50 million in a startup making sustainable aviation fuel from ethanol. The Breakthrough Energy fund made the grant to LanzaJet, which is building its first commercial plant. LanzaJet's ethanol is derived from products like sugarcane and waste corn.
An organization founded by Bill Gates has granted a startup $50 million to build a massive refinery that produces sustainable aviation fuel from alcohol.
On Wednesday, LanzaJet announced it had received the funds from the Gates-led Breakthrough Energy fund, to continue work on its first commercial plant in Soperton, Georgia.
Sustainable aviation fuel is being explored by airlines as a way of making the industry more environmentally friendly. Currently, its adoption has been hampered due to the relatively low amounts produced.
We need to make the 'green way' far less expensive than it is today, says Breakthrough Energy Founder Bill Gates
The Soperton facility, known as the Freedom Pines Fuel Plant, is set to begin production in 2023. LanzaJet said the plant would produce nine million gallons of sustainable aviation fuel, and one million gallons of renewable diesel, per year when fully-operational.
The funds will help the company meet its development timeline for the plant, which will roughly double the amount of sustainable aviation fuel made in the US, LanzaJet said.
LanzaJet produces the fuel using ethanol from products like sugarcane and waste corn. The company said it will lower emissions by at least 70% compared with conventional aviation fuel.
Gates founded Breakthrough Energy to boost innovation and investment in clean energy technology. The $50 million grant comes from Microsoft Corporation, BlackRock Foundation, Builders Vision, and Gates, per Bloomberg.
It adds to the millions of dollars of support LanzaJet has already received, including a $14 million grant from the US Department of Energy, and a combined $200 million from backers including British Airways and Shell, per Bloomberg. In January, Microsoft's Climate Innovation Fund, also founded by Gates, invested another $50 million towards the project.
In December, United Airlines flew a passenger flight using 100% SAF. The Boeing 737 Max 8 flew from Chicago O'Hare to Washington DC with 500 gallons of SAF in one engine and 500 gallons of traditional jet fuel in the other.
