Colombia Accuses U.S. Coal Miner Of Funding Paramilitary Group

The current head of Drummond in Colombia and his predecessor will be tried on charges of financing a paramilitary group, Reuters has reported, citing the office of Colombia’s attorney general.

According to prosecutors, there was “abundant evidence” that Augusto Jimenez and Miguel Linares, who headed the company from 1990 and 2012, and from 2013 onwards, respectively, had used company funds for illicit support to a right-wing group.

"Linares Martinez and Jimenez Mejia, between 1996 and 2001, increased the value of a food provision contract with a provider company to obtain additional resources and use them to cover previously-agreed illegal obligations with...the United Self-Defense Forces of Colombia (AUC)," a statement by the attorney general’s office said.

The purpose of the illicit transfers was to secure mining assets operated by the company in areas where the paramilitary group had a presence.

"These accusations are not backed up with credible proof and are based, principally, on false declarations by convicted criminals, who receive payments for testimony," Drummond said in response to the news.

The U.S.-based company is the biggest producer of thermal coal in Colombia, Reuters noted in its report, with total exports of the commodity this year seen at 30 million tons by Miguel Linares.

The news of the charges against Linares and his predecessor comes a day after Drummond’s Colombian unit announced plans to become a net-zero company by 2050. Measures would include switching from gas to electricity at one mine in the country, switching from gasoline to gas for its light vehicle fleet, and emission offsets for the carbon dioxide the company cannot reduce.

"We're looking for projects to see where we can reduce our emissions, how to offset what we cannot avoid and include all our allies in a commitment to reaching carbon neutrality by 2050," Linares told media without mentioning the price tag of the push into carbon neutrality.

Colombia’s President May Have To Rethink His Oil And Gas Exploration Ban

  • Colombia’s oil and gas industry already suffers from a shortage of proven reserves, a fact that will be made worse if President Petro ends new exploration efforts.

  • The country’s President hopes to stop new exploration contracts from being awarded and plans to ban hydraulic fracturing in the country.

  • Colombia’s oil- and gas-dependent economy will face significant turmoil in the coming years if it is unable to replace its proven reserves.

Colombia’s economically crucial energy patch is facing a grave crisis due to its shortage of proven oil and natural gas reserves coupled with leftist President Gustavo Petro’s plan to end awarding new exploration contracts. The Andean country’s hydrocarbon sector was hit particularly hard by the 2020 COVID-19 pandemic and has yet to recover. March 2023 oil production of 771,732 barrels a day was significantly less than the 884,876 barrels per day pumped for the same month four years earlier. Latest developments indicate Colombia’s economically vital oil patch may never return to a pre-pandemic operational tempo and production volumes. As a result of Petro’s plans to end awarding new exploration contracts and ban hydraulic fracturing, investment is falling, drilling activity is in decline, and international energy companies are even exiting Colombia. 

The latest news, which represents a considerable blow to Colombia’s oil industry, is the disappointing announcement from the Ministry of Mines and Energy that the Andean country’s reserves are not growing at the pace required. According to the ministry’s statement (Spanish) oil reserves only expanded by 1.7% year-over-year to a meager 2.074 billion barrels of oil with a commercial life of 7.5 years at the current rate of production. Of greater concern is proven natural gas reserves, which plunged by 11% compared to a year ago to 2.82 trillion cubic feet, only enough to support production for 7.2 years. Those meager reserves are incapable of supporting Colombia’s economically crucial hydrocarbon sector over the long term. The lack of hydrocarbon reserves and their short production life has the potential to roil Colombia’s oil-dependent economy.

A key issue to emerge is that vital capital spending in Colombia’s energy patch is falling. According to the country’s leading industry body, the Colombian Petroleum Association (ACP – Spanish), private investment in exploration (Spanish) during 2023 will fall by a third compared to last year, hitting $650 million to $700 million. That decline is reduced to 4% year-over-year, when increased exploration spending by national oil company Ecopetrol is accounted for, or $1.24 billion compared to $1.29 billion during 2022. Such a sharp reduction in investment will lead to reduced exploration and oilfield development activity thereby weighing on reserves and production volumes at a crucial time for Colombia.

This has been an ongoing problem since the price of oil collapsed in late-2014. Colombia’s oil industry regulator, the National Hydrocarbon Agency (ANH – Spanish initials), released data showing the volume of wells (Spanish) being drilled in Colombia cratered after 2014. During that year, when Brent averaged $98.97 per barrel, 113 wells, 112 onshore and one offshore, were drilled. A year later, in 2015, when Brent averaged $52.32 a barrel, a mere 25 wells, 23 onshore and two offshore, were completed. The volume of wells being drilled plunged to an annual multiyear low of 20 during 2020 when the COVID-19 pandemic caused oil prices to plunge into negative territory for the first time ever and Brent averaged $41.96 a barrel. 

Drilling activity only significantly recovered when oil prices soared, after Russia’s invasion of Ukraine, to a multi-year high of 68 wells, 66 onshore and two offshore. Regulator data shows that 10 wells were completed for the first two months of 2023, and industry body the ACP predicts 55 to 60 exploratory wells will be drilled in Colombia this year. According to the Baker Hughes Rig Count, by the end of April 2023, there were 31 active rigs in Colombia a decrease of three compared to a month earlier and the same number as a year earlier. Those numbers point to a sharp drop in activity in Colombia’s oil patch which doesn’t bode well for higher production or the ability to boost meager reserves. 

This is threatening Colombia’s long-term energy security and the future outlook for the hydrocarbon-dependent economy which is vulnerable to weaker oil prices and declining production. The considerable risks created by a lack of exploration success and meager proven reserves are magnified by many of Colombia’s primary producing oil fields being mature with rising decline rates. That means they are reliant on enhanced recovery methods such as waterflood, and gas injection to sustain production. This is impacting efforts by Bogota, the ANH, and ACP as well as other industry bodies to lift production so that it returns to pre-pandemic levels of nearly 900,000 barrels per day.

Colombian government as well as industry data underscores how dependent the economy is on oil. Official statistics agency DANE shows that petroleum was responsible for (Spanish) a third of exports by value during 2022, while for the same year the hydrocarbon sector was responsible for 2.6% of gross domestic product. Colombia’s oil industry is a key source of income for the national government in Bogota. A decade ago, petroleum, after including dividend income from 88% state-controlled Ecopetrol was responsible for a fifth of fiscal revenue, while that amount has fallen in recent years it amounted to 14% of fiscal revenue for 2022. The proportion of government revenue contributed by Colombia’s oil industry will only increase after Petro’s November 2022 tax hikes.

It is Bogota’s reliance on oil revenues that has sparked speculation that Petro will not proceed with his plan to end hydrocarbon exploration in Colombia. This was fueled by Energy Minister Irene Velez reportedly avoiding answering questions from journalists as to whether the Petro administration will issue new exploration and production contracts after the productive life of Colombia’s proven oil reserves declined. Any immediate move to end oil exploration and production has the potential to damage Colombia’s oil-dependent economy which is an important part of the Andean country’s post-pandemic economic recovery. 

According to the International Monetary Fund, Colombia’s gross domestic product grew by a stunning 11% in 2021 and then 7.5% during 2022, but that will fall to a mere 1% in 2023 with a lack of energy investment and dwindling oil production weighing on the economy. In an effort to assuage the worries of energy investors, the ANH has proposed expanding deadlines, for drilling timetables, for oil and natural gas exploration projects to attract greater interest from foreign energy investors. The regulatory agency also suggested providing energy companies with greater contractual flexibility when forced to declare force majeure. These latest developments indicate that Petro may be rethinking his plan with regard to ending hydrocarbon exploration in Colombia, and even may implement a more gradual and pragmatic policy.

Norway's Wealth Fund  Sides With Activists Against Exxon, Chevron

  • The year 2021 proved to be a watershed moment for oil and gas companies in the global transition to clean energy, with Big Oil losing a series of boardroom and courtroom battles in the hands of hardline climate activists.

  • Norway’s giant sovereign wealth fund announced it will support proposals by ExxonMobil Corp. and Chevron Corp. shareholders at their annual general meetings (AGMs) on Wednesday to introduce emissions targets.

  • In May 2022, Exxon recorded a major victory after its shareholders supported the company's energy transition strategy at the annual general meeting.

Climate activists have scored yet another victory against Big Oil after Norway’s giant sovereign wealth fund announced it will support proposals by ExxonMobil Corp. (NYSE:XOM) and Chevron Corp. (NYSE:CVX) shareholders at their annual general meetings (AGMs) on Wednesday to introduce emissions targets. With $1.4 trillion in assets, Norway's wealth fund is the largest in the world, and its voice on matters like these carries plenty of weight. The fund is the sixth-largest investor in Exxon with a nearly 1.2% stake. The move comes barely a week after climate protesters unleashed chaos at TotalEnergies’ (NYSE:TTE) AGM in Paris which saw shareholders back a motion calling for the French energy giant to speed up cuts to its greenhouse gas emissions. Similarly, in what is now shaping up as another wave of climate fervor, protesters stormed Shell Plc’s (NYSE:SHEL) AGM last week, accusing the Dutch national oil company of "killing" the planet and calling for it to be "shut down".

It’s a startling turn of events for oil and gas shareholders considering that last year, there was a palpable shift in sentiment with climate activism and ESG taking a back seat amid the global energy crisis.

Shifting Sentiment

The year 2021 proved to be a watershed moment for oil and gas companies in the global transition to clean energy, with Big Oil losing a series of boardroom and courtroom battles in the hands of hardline climate activists.

In May 2021, ExxonMobil lost three board seats to Engine No. 1, an activist hedge, in a stunning proxy campaign. Engine No. 1 demanded that Exxon needs to cut fossil fuel production for the company to position itself for long-term success. "What we're saying is, plan for a world where maybe the world doesn't need your barrels," Engine No.1 leader Charlie Penner told the Financial Times. Engine No. 1 enjoyed a stunning victory thanks to support from BlackRock Inc. (NYSE: BLK), Vanguard and State Street who all voted against Exxon’s leadership.

Next was its close peer Chevron with no less than 61% of Chevron shareholders voting to further cut emissions at the company’s annual investor meeting and rebuffing the company’s board which had urged shareholders to reject it. 

Finally, a Dutch court ordered Shell Plc to cut its greenhouse gas emissions harder and faster than it had previously planned. Never mind the fact that Shell had already pledged to cut GHG emissions by 20% by 2030 and to net-zero by 2050. The court in The Hague determined that wasn’t good enough and demanded a 45% cut by 2030 compared to 2019 levels. The past two years have been especially challenging for Shell shareholders after the company announced a major dividend cut with the quarterly dividend falling to 16 cents from 47 cents, the first dividend cut since WWII. Meanwhile, the company’s debt had ballooned massively from $1bn in 2005 to $73bn in 2020.

Luckily for these oil and gas supermajors, last year, investor sentiment shifted in their favor.

In May 2022, Exxon recorded a major victory after its shareholders supported the company's energy transition strategy at the annual general meeting. Only 28% of the participants backed a resolution filed by the Follow This activist group urging faster action to battle climate change; a proposal calling for a report on low carbon business planning received just 10.5% support while a report on plastic production garnered a 37% favorable vote.

Following in the footsteps of its larger peer, in June, Chevron shareholders voted against a resolution asking the company to adopt greenhouse gas emissions reductions targets, indicating support for the steps the company already has taken to address climate change.

Just 33% of shareholders voted in favor of the proposal, according to preliminary figures disclosed by the company, a sharp turnaround from last year when 61% of shareholders voted to support a similar proposal.

Encouraged by the previous year’s victories including rules that made it easier to put public policy-related questions on proxy ballots, an analysis by the Conference Board of data supplied by Esgauge revealed that last year, climate activists  filed nearly 400 environmental and social proposals with member companies of the Russell 3000 index. However, the share of support for environmental proposals dropped from 37% in 2021 to 33% in 2022, reflecting a growing aversion by asset managers to tying managers’ hands on climate-related issues. Russia’s invasion of Ukraine has also forced investors and companies to think more about energy security.

But it’s now becoming increasingly clear that climate activists are not about to go down without a fight. And, more and more institutional investors are becoming powerful climate advocates. Two years ago, New York City’s Mayor Bill de Blasio and Comptroller Scott M. Stringer sent shockwaves through the oil and gas sector after they announced that the city’s $226B pension fund plans to divest majority of its fossil fuel investments over the next five years and also cut ties with other companies that have been contributing to global warming.

Around the same time, Rockefeller Brothers Fund, a family foundation built on one of the world’s biggest oil fortunes, followed suit by announcing that it would ditch its oil and gas investments and cease making any new investments going forward. The $5-billion foundation was initially carved from oil money in the 19th century by John D. Rockefeller’s son of Standard Oil fame.

Finally, BlackRock Inc.(NYSE:BLK) CEO Larry Fink said he would start to pressure companies to do a lot more to lower their carbon emissions by leveraging the massive weight of his mammoth asset base. BlackRock is the world’s largest asset manager with $9.1 trillion in assets under management (AUM).

As you might expect, opponents of boardroom activism have dismissed the latest move from Norway's wealth fund while clean energy buffs welcomed them as a beacon for the growing fossil fuel divestment movement. But at least oil and gas investors can take some comfort in that these companies are not likely to run out of backers any time soon, with private equity firms gladly stepping in as more traditional financiers balk.

Nucleoelectrica sets out plan for Atucha II repair

30 May 2023


A life-size mock-up of the reactor and special tools have been designed and built ahead of the repair procedure which the operating company hopes will take place next month at Argentina's Atucha II nuclear power unit.

The reactor has been closed since October 2022 when a routine inspection "detected that one of the four internal supports of the reactor had detached and moved from its design location". Operator Nucleoelectrica Argentina (NA-SA) said that it is a "mechanical failure of the plant" but does not present a risk to the safety of people of the environment.

In a progress update the company said that a diagnosis of the failure was made by mechanical and hydraulic studies and "it was decided to extract the part and work began on the use of state-of-the-art engineering methods for the implementation of robotic and technological tools that allow optimising repair times, in order to return to service as soon as possible".

The detached separator is 14 metres deep inside the reactor so tools needed to be designed to adapt to those conditions, including a cutting tool, holding tool, gripper, a basket within which to extract the piece as well as lighting and vision tools to monitor the manoeuvre. "It was also necessary to develop a pressure welding tool and method to preventatively weld the three remaining spacers that did not come off," said NA-SA.

To practice the cutting and extraction manoeuvres and test the tools a full scale model of the reactor sector was designed - "the container used in the repair of the Atucha 1 Nuclear Power Plant in 1988 was reconditioned ...  all the internal elements were manufactured on a 1:1 scale and placed inside this chamber".

Argentina's Nuclear Regulatory Authority is currently reviewing the plan for the repair, which was submitted earlier this month. Its technical personnel have also been inspecting the work in the test facility "to validate the proposed method and the development of implementation procedures ... to verify compliance with nuclear and radiological safety premises". Nucleoelectrica Argentina is hoping to be able to begin the work in June.

Argentina's nuclear sector has three pressurised heavy water reactors with a total generating capacity of 1641 MWe across the Atucha 1, Atucha 2 and Embalse power plants. Atucha II's first grid connection was in 2014 - construction began in 1981 as a joint venture of CNEA and Siemens-Kraftwerk Union but work was suspended in 1994 with the plant 81% complete. It was restarted in 2006, entering commercial operation in May 2016.

Collaborations announced for fusion projects

30 May 2023


General Atomics (GA) of the USA and Tokamak Energy of the UK have agreed to collaborate in the area of high temperature superconducting (HTS) technology for fusion energy and other industry applications. Meanwhile, Germany's Max Planck Institute for Plasma Physics will work with Proxima Fusion to further develop the stellarator concept.

GA - which began working on superconducting magnet technologies in the 1980s - and Tokamak Energy said the collaboration under a newly-signed memorandum of understanding would "leverage GA's world-leading capabilities for manufacturing large-scale magnet systems and Tokamak Energy's pioneering expertise in HTS magnet technologies".

Magnetic fusion uses a tokamak, which uses several sets of powerful electromagnets to shape and confine superheated hydrogen gas - known as plasma. To achieve fusion conditions relevant for energy production, tokamaks must heat the gas to temperatures exceeding 100 million degrees Celsius - more than ten times the temperature at the centre of the sun. This is the threshold said to be required for fusion to be a commercially viable energy source.

Strong magnetic fields are generated by passing large electrical currents around arrays of electromagnet coils that circle the plasma. The magnets are wound from ground-breaking HTS tapes, multi-layered conductors with a crucial internal coating of 'rare earth barium copper oxide' (REBCO) superconducting material. Developing more powerful HTS magnets will allow fusion power plants to use thinner magnetic coils while generating plasmas at greater densities.

"GA is excited to collaborate with Tokamak Energy on HTS magnets," said GA Senior Vice President Anantha Krishnan. "Tokamak Energy is a leader in HTS magnet modelling, design and prototyping and GA has expertise in developing and fabricating large-scale superconducting magnets for fusion applications."

"GA has significant experience, knowledge and facilities to produce large superconducting magnets at scale," said Tokamak Energy Managing Director Warrick Matthews. "Tokamak Energy has been developing HTS technologies for fusion for over a decade. The integration of these complementary capabilities promises to accelerate the development and production of HTS technologies in additional fields, such as aviation, naval, space and medical applications."

Tokamak Energy's roadmap is for commercial fusion power plants deployed in the mid-2030s. To get there the plan is for completion of ST80-HTS in 2026 "to demonstrate the full potential of high temperature superconducting magnets" and to inform the design of its fusion pilot plant, ST-E1, which is slated to demonstrate the capability to deliver electricity - producing up to 200 MW of net electrical power - in the early 2030s.

Collaboration in stellarators


The Max Planck Institute for Plasma Physics (IPP) has signed a cooperation agreement with Munich-based Proxima Fusion - which was spun out of IPP earlier this year and was founded by a team which includes six former IPP scientists - to further develop the stellarator concept for fusion power. Proxima Fusion intends to design a nuclear fusion power plant based on IPP research.

"With this cooperation, Proxima Fusion will primarily advance technological approaches, while IPP will contribute its know-how as the world's leading institute in stellarator physics," IPP said.

The institute is the only institution in the world that carries out research on both essential concepts of magnetic confinement fusion with the help of large-scale experiments: it operates the ASDEX Upgrade tokamak in Garching near Munich, and the Wendelstein 7-X stellarator in Greifswald.

A tokamak is based on a uniform toroid shape, whereas a stellarator twists that shape in a figure-8. IPP notes the advantage of stellarators is that they can be operated continuously, unlike pulsed tokamaks, and with better plasma stability properties.

In February, the Wendelstein 7-X stellarator succeeded for the first time in generating a high-energy plasma that lasted for eight minutes. The facility is designed to generate plasma discharges of up to 30 minutes in the coming years. Scientists are also working in the field of stellarator optimisation at IPP's Stellarator Theory Division in Greifswald.

"With our research, we want to further develop stellarators towards application maturity," said IPP Scientific Director Sibylle Günter. "With Proxima Fusion's technological focus, we see great synergies in a collaboration and look forward to working together in a public-private partnership".

Vogtle 3 reaches full power

30 May 2023


The unit is now in the final stages of start-up testing ahead of starting commercial operation and is expected to be declared in service next month.

The AP1000 unit reached first criticality in March and was connected to the electricity grid in April. It has been undergoing testing through the full range of plant operations at gradually increasing power levels in a process known as power ascension testing.

The operation of the reactor, control systems for the reactor and support systems, and integrated plant operations are tested at each power level, with plant performance monitored under various conditions. Now the unit has reached 100% power, further tests must now be performed before it is available for reliable dispatch in accordance with its combined operating licence, Southern Company said.

"As we enter the final stages of start-up testing, reaching 100 percent power for the first time is an exciting milestone. It tells us we're close to finishing the unit safely and bringing it online to power Georgia homes and businesses with reliable, emissions-free energy for decades to come," Georgia Power President and CEO Kim Greene said.

It is now just over 10 years since construction of two Westinghouse AP1000s began at the site near Waynesboro. Work started on unit 3 in March 2013 and unit 4 in November of that year. Unit 4 completed hot functional testing - which confirms the reactor is ready to be loaded with nuclear fuel - earlier this month. The first fuel for unit 4 was delivered on 3 May, ahead of fuel loading later this year. Vogtle 4 is expected to enter service late this year or early in 2024.

Southern Nuclear and Georgia Power, both subsidiaries of Southern Company, took over management of the construction project in 2017 following Westinghouse's Chapter 11 bankruptcy. The units are co-owned by Georgia Power, Oglethorpe Power, MEAG Power and Dalton Utilities, and will be operated by Southern Nuclear.

Robotic hand offers innovative nuclear solution

31 May 2023


Atkins and COVVI Robotics plan to develop a robotic solution using a bionic hand that would provide "near-human" dexterity for handling nuclear materials remotely, removing the need for operators to place their hands in gloveboxes when handling nuclear materials and wastes.

Building on SNC-Lavalin group member Atkins' patented work to deploy collaborative robots in the nuclear sector, the two firms aim to attach COVVI's bionic hand to a robotic arm, to enable dangerous manipulations to be carried out by remote control while more closely replicating human dexterity. This will reduce the presence of humans in hazardous areas and enable glovebox operations to continue over longer periods of time, reducing risk and increasing efficiency, as well as freeing up time for site operators to focus on other activities, the companies said.

COVII's bionic hand was originally developed for people with an upper limb difference, but - when paired with a remote control system - its small weight, size and high levels of dexterity make it ideal for use in small environments, the company says.

Atkins and COVII said they have already been working together for the last six months to develop the integration between the robotic hand and collaborative robots such as Kinova Robotics' Gen3 arm that Atkins already uses to work in gloveboxes, and now intend to develop and market a new variant of COVVI's bionic hand optimised to meet the needs of the nuclear sector. Atkins is also developing a digital twin to rehearse and pre-plan glovebox activity to increase efficiency.

"Robotics hold huge potential for the nuclear sector and we expect their use to become increasingly common over the coming decade as the industry seeks to improve safety, increase efficiency and address increasing skills shortages," SNC-Lavalin's Head of Digital, Nuclear, Sam Stephens said, adding that such collaboration was crucial to help accelerate innovation and bring forward new solutions to address some of the sector's biggest challenges swiftly and cost-effectively. "The new robotic hand has the potential to reduce risk and improve productivity for the nuclear operators that we work with in partnership around the world, and we look forward to seeing it deliver results soon," he said.

"The robotics market continues to develop at pace as it becomes more affordable, scalable, and customisable," COVVI Group CEO Simon Pollard said.

IAEA finds Fukushima water sampling meets requirements

31 May 2023


Tokyo Electric Power Company (Tepco) has demonstrated its capabilities for accurate and precise measurements of the radionuclides present in the treated water stored at the Fukushima Daiichi site, according to an International Atomic Energy Agency (IAEA) report.

At the site, contaminated water - in part used to cool melted nuclear fuel - is treated by the Advanced Liquid Processing System (ALPS), which removes most of the radioactive contamination, with the exception of tritium. This treated water is currently stored in about 1000 tanks on site. The total tank storage capacity amounts to about 1.37 million cubic metres and all the tanks are expected to reach full capacity in late 2023 or early 2024.

Japan announced in April 2021 it plans to discharge treated water stored at the site into the sea over a period of about 30 years, and asked the IAEA to review its plans against IAEA safety standards.

Consistent with relevant IAEA international safety standards, Tepco is required to monitor the characteristics and activity of the treated water in order to accurately evaluate public exposure due to the discharge and to comply with its national regulatory authorisation.

As part of its multi-annual safety review, the IAEA is independently checking the types and amounts of radionuclides contained in the ALPS treated water.

The IAEA has now released its latest report covering its independent sampling and analysis work. The IAEA observed and facilitated the collection of the treated water samples analysed in the report from tanks at the Fukushima Daiichi site in March 2022. This water was taken from the first batch of ALPS treated water expected to be discharged into the sea.

The samples were corroborated based on an interlaboratory comparison which involves different laboratories separately testing and analysing samples and then comparing results and procedures to determine their reliability and accuracy. The samples taken for the report were analysed by Tepco; by the IAEA in its laboratories in Monaco, and in Seibersdorf and Vienna, Austria; and in third-party laboratories in France, South Korea, Switzerland and the USA.

Additional samples have been taken from other batches of water and are undergoing a similar analysis as part of the wider review process.

"This report and the analytical results that it contains are an important milestone in the IAEA's safety review," said Gustavo Caruso, Director and Coordinator for the ALPS Safety Review, IAEA Department of Nuclear Safety and Security and Chair of the Task Force. "The data demonstrates Tepco's analytical performance through a transparent and rigorous scientific process."

Additional reports on corroboration will cover baseline environmental samples (eg seawater and fish) from the surrounding environment of the Fukushima Daiichi site and an assessment of the capabilities of monitoring services involved in the assessment of internal and external radiation exposure of workers at the plant.

The report was released as the IAEA Task Force conducting a safety review of Japan's plan to release treated water into the sea carries out its final mission to Japan before publication of the agency's comprehensive report.

During the mission - being held from 29 May to 2 June - the Task Force is meeting in Tokyo with Tepco, as well as with the Ministry of Economy, Trade and Industry and the Nuclear Regulation Authority (NRA).

"The Task Force will use this opportunity to receive updates from Tepco and the Government of Japan regarding their work over the past few months and to confirm our understanding of different technical details – this will help us as we prepare the comprehensive assessment of the safety of Japan's plan for the water release," Caruso said.

The IAEA's comprehensive report will include a broad assessment of Japan's plan to discharge the treated water against relevant international safety standards, factoring in all insights and outcomes from all previous missions. Japan intends to start discharging the ALPS treated water in 2023 having received the NRA's regulatory approval for the plan in May last year.

South Korean inspection


Last week, a team of South Korea experts visited the Fukushima Daiichi site to inspect equipment and facilities to be used in the discharge process. The team comprised 21 experts from the Korea Institute of Nuclear Safety and the Korea Institute of Ocean Science and Technology.

In a statement, Korea's Nuclear Safety and Security Commission said: "This visit focused on matters requiring on-site confirmation as part of the scientific and technological review process that the Korean government has been conducting since August 2021."

The team inspected the plant's treatment facilities, such as ALPS, and the K4 tanks storing the treated water. They also inspected the mechanisms of the underwater tunnel to be used for discharging the treated water into the sea.

"This visit has made significant progress in the process of scientific and technological review through direct on-site confirmation and more detailed data acquisition, but additional analysis and confirmation work is planned for more precise judgment," Yoo Gook-hee, head of the inspection team said. "Based on this, we plan to comprehensively evaluate Japan's plans for Fukushima-related water pollution and disclose the results."
