On 27 February 2022, the International Atomic Energy Agency (IAEA) was alerted by Ukraine’s Foreign Ministry that the Russian army was approaching the Zaporizhzhia Nuclear Power Plants (NPP) complex.1 Within a week, Russia informed IAEA that its military took control of the area around the Zaporizhzhia NPP.2 After the Fukushima Daiichi accident, this was the first time when the IAEA’s International Incident and Emergency Centre (IEC) immediately went to the highest alert.3 The Director General of the IAEA, Rafael Grossi, warned that an accident at nuclear facilities could have severe repercussions.4

The shellings and war activities near Zaporizhzhia NPP have raised concerns in the international community about the safety and security of the nuclear reactors. Grossi termed the shellings as ‘playing with fire’ due to the risk of nuclear catastrophe.5 Concerns about the quality of the safety systems of the reactor and the ability of the reactor design to withstand missile attacks were raised. The possibility of a technological error that could lead to an accident similar to Chernobyl, or a blackout situation similar to Fukushima, were also raised.

The IAEA Director General called for restraint and reiterated the seven pillars of nuclear safety and security based on existing nuclear safety and security conventions. These are the need to maintain the physical integrity of the facilities; a functional security system and equipment; staff being able to do their duties without any pressure; availability of an off-site power supply; uninterrupted transportation and supply chain from and to the site; effective monitoring system and emergency preparedness and response measures; and reliable communication with the regulator and others.6

After Russia took control of Zaporizhzhia plant under the management of Russian state atomic energy corporation ‘Rosatom’7 , staff were required to take approval from the local Russian commander to operate and maintain the power plant.8 The President of Ukrainian national nuclear energy generation company Energoatom9 , informed the IAEA in March 2022 that about 400 Russian soldiers were present at the plant.10

Reports noted that the Russian army was using the plant as a cover to fire at the city.11 In the ongoing conflict, multiple arms were used at Zaporizhzhia nuclear power plant. For instance, on 4 March 2022, the first missile hit the ZNPP training building causing a fire.12 No radiation leakage though was detected.13 Later the fire was extinguished14 and some unexploded munition found at that training building were disposed.15 Such indiscriminate use of weapons was said to be affecting the morale and emotional state of the plant employees,16 violating the third pillar of nuclear safety and security.

The war activities have compromised other pillars of nuclear safety and security as well. For instance, the transfer of safeguards data from ZNPP was interrupted multiple times though it was re-established within few days.17 Due to the shellings, the plant’s external power supply system was damaged, a unit was disconnected from the grid, a security guard at ZNPP was injured, spent fuel storage facility sustained damages in its walls,  but there was no damage to the spent fuel container nor was any radiation leakage detected.18

After Russian shellings became frequent, the Ukrainian government requested the IAEA and UN Secretary-General Antonio Guterres to redouble their efforts.19 In response, the IAEA delivered monitoring equipment to ZNPP offered by Australia and France, which are among 12 of IAEA’s ‘Response and Assistance Network ’ (RANET) countries. The IAEA also delivered more than 160 radiation measurement devices and protective equipment, including masks, gloves, full-body suits, among others.20

While shellings near Zaporizhzhia do involve serious risks, they may not result in an accident like Chernobyl or Fukushima. The Chernobyl accident happened due to insignificant understanding and lack of safety technology.21 The reactors of Chernobyl NPP did not have a containment building.22 Modern reactors like Zaporizhzhia are designed with protection against events such as aircraft crashes, fire, explosions, flood, and extreme meteorological conditions, etc.23 The reactors of Zaporizhzhia have 1.2 meters thick concrete shell and are designed to withstand explosions and crash of an airplane.24 Thus, it can be said that the containment building should be able to resist missile attacks.

Other than the reactor, the spent fuel storage facility contains liquid and solid waste which can cause potential radiation hazard, if damaged. However, after multiple shellings at Zaporizhzhia plant, the spent fuel container was not damaged and the cooling system has been good enough to maintain the temperature and radiation level under control.25

Without external power, the reactor as well as the spent fuel storage might lose the cooling system. Therefore, multiple power supply systems are needed. If the external power supply is disconnected for cooling water to circulate, the loss of power could result in an accident like Fukushima. There are three back-up power supply of 330 kV and three off-site power lines of 750 kV connected to a nearby thermal power plant in case the back-up power supply gets disconnected.26 Even if the reactor is shut down, it still requires electricity to maintain the reactor temperature, hence backup power and off-site power supplies are crucial for nuclear safety.27

If the external sources of power supply are lost, then the nuclear plant has to depend on emergency diesel generators. This situation has been occurring time and again during the conflict.28 When the plant lost the power for cooling system, it first relied upon the power generated by the plant itself and then on back-up power line linking to the grid through the nearby thermal power plant.29 There are 20 diesel generators on site and nine of them are operating (as of November 2022) to provide power to all the six reactors and ensure the safety of the plant.30 These diesel generators have enough power to operate up to 15 days without any external power supply.31 The reactor had to rely on diesel generator multiple times through the conflict but every time the emergency diesel generators started automatically and operated till the back-up power was available. 32

The IAEA was not able to visit ZNPP since the conflict began but on 1 September 2022, experts, as part of the IAEA Support and Assistance Mission to Zaporizhzhia (ISAMZ), were finally able to arrive at the Zaporizhzhia NPP.33

After 20 November 2022, there has been no shelling on the site per se but there has been shelling in the nearby areas. Zaporizhzhia NPP has been reconnected to the off-site power through a 750 kV external power line and a 330 kV back up line.34 An additional 330 kV power line as a back-up is being repaired, as informed to the IAEA by Rosatom.35 On 31 October 2022, four of the six reactors were kept under cold shutdown which requires less energy for cooling and the other two reactors are under hot shutdown, which allows them to supply heat to the nearby city.36

In conclusion, it can be said that Zaporizhzhia NPP has better and proven technology with multiple safety systems and multiple power supply, along with a strong containment building that is designed to withstand terrorist attacks and crash of an airplane.37 Despite the ongoing military activities, the IAEA has been inspecting the Zaporizhzhia nuclear facilities and has stated that no radiation leakage has been detected in those facilities. Nonetheless, the complete demilitarisation of Zaporizhzhia NPP is essential to assure the full safety of the plants.

Concerns for Pacific democracy, but no crisis yet

Author: Kerryn Baker, ANU

In 2022, considerable pressure was put on democratic norms and practices in the Pacific Islands. Taken together, the year’s events paint a bleak picture of democratic resilience in the region. But there are also bright spots of progress to celebrate, notably in terms of women’s political representation.

The two largest Pacific Islands states both went to the polls in 2022. The Papua New Guinean (PNG) general election was plagued by delays, issues with the electoral roll and concerning incidents of violence, resulting in many fatalities and thousands of displaced citizens. Transparency International PNG stated that the election ‘continued the trend of deterioration in the quality of elections in PNG’.

The general election in Fiji — pitched as a showdown between two former coup leaders, the incumbent Prime Minister Frank Bainimarama and challenger Sitiveni Rabuka — resulted in a hung parliament, with the Social Liberal Democratic Party (SODELPA) holding the balance of power.

In the aftermath of the election, amid messy negotiations to form coalition government, there were serious concerns that a peaceful transfer of power would not take place. Rabuka accused Bainimarama of ‘sowing fear and chaos’ in an attempt to maintain power. But ultimately, an agreement was reached between Rabuka’s People’s Alliance, SODELPA and the National Federation Party. On Christmas Eve, Rabuka was sworn in as Prime Minister, a significant milestone in Fiji’s democratic history.

Across the region, there are concerning trends related to the practice of democracy between elections too. In Kiribati — which withdrew from the Pacific Islands Forum in July 2022 — the government attempted to deport one of its high court justices, David Lambourne, who is also the husband of Kiribati’s opposition leader. In the aftermath, four other senior judges were suspended, leaving the country without an operational high court. Kiribati’s attorney-general was appointed acting chief justice in October. The New Zealand Law Society argued that this appointment ‘would challenge the independence of the judiciary and constitutional separation of powers that is fundamental to a functioning democracy’.

In Solomon Islands, the upcoming election — originally scheduled to be called by May 2023 — was delayed until 2024, with the government claiming it could not afford to host the Pacific Games and hold an election in the same year. Peter Kenilorea Jr, a member of the opposition and outspoken critic of the government, labelled it ‘an authoritarian move’. Extending terms of government has also been done before in the region, notably in Samoa in the early 1990s.

These moves came after the controversial security pact that Solomon Islands signed with China earlier in 2022, which prompted significant concern and renewed attention from Western powers. Solomon Islands and Kiribati switched diplomatic recognition of Taiwanese sovereignty to China in 2019.

While concerning, none of the issues highlighted above are new. Electoral issues in PNG and constraints on civil liberties in Fiji have been well-documented by academics and non-governmental organisations. The use of foreign judges and the potential use of deportation as a threat against them has been a long-standing issue, particularly in the former British colonies of the Pacific.

In the postcolonial era, a perennial debate in the region has been around democracy and whether it is a ‘foreign flower’, unsuited for the Pacific environment. This belies the fact that, on the whole, the region has a quite extraordinary postcolonial history of democratic continuity. The majority of Pacific states have unbroken track records of regularly scheduled elections and peaceful transfers of power.

But the crisis narrative has continuously emerged. In the late 1980s, former Australian foreign minister Gareth Evans noted increased Australian interest in the region as a result of political turmoil in Fiji, New Caledonia and Vanuatu, saying the Fiji coups in particular represented ‘a blow to democratic principle’. In the early 2000s, the Australian government labelled Melanesia an ‘arc of instability’ and think tanks warned that without external intervention, failed states would emerge in the region.

While there is certainly reason for concern about the current state of democracy in the Pacific, there are also opportunities for optimism. Despite fears of military intervention, the election in Fiji resulted in a peaceful transfer of power, an encouraging sign for democratic consolidation. Another promising development in the region is the increased participation of women in politics, with further advances in this space following the 2021 election of Samoa’s first woman prime minister, Fiame Naomi Mata’afa.

After years of languishing at the bottom of global league tables with zero women members of parliament, both PNG and Vanuatu saw a change this year. Rufina Peter and Kessy Sawang were elected in PNG, while Gloria Julia King won a seat in Vanuatu’s October snap election. Following by-elections in Tonga in November, there is now — for the first time ever — at least one elected woman member of every Pacific parliament.

2023 will bring renewed attention from the United States and other Western powers as the Pacific once again becomes a site of geopolitical contestation. Democracy support and promotion programs will play an important, but perhaps contested, role. Elections and parliaments are the cornerstones of democratic systems, but the strength of democracy relies on a broader ecosystem encompassing the media, civil society, education systems and the inclusion of historically underrepresented groups. Democratic norms and practices have a solid foundation in the Pacific, but the events of 2022 prove that this cannot be taken for granted.

'Unusual sight' as sharks seen swimming in 'cartwheel' formation


By 9News Staff
Jan 3, 2023

Scientists conducting an aerial survey of the ocean off the coast of New England in the US have come across some "unusual" behaviour.

The group witnessed several clusters of basking sharks swimming in what they called a "cartwheel formation", according to New England Aquariam.

Basking sharks are the second-largest living shark and fish after the whale shark.

" Usually, we see basking sharks swimming alone, so this was quite surprising," the post reads.

The post also said scientists with the aquarium had also spotted an aggregation of about 1,400 basking sharks near Martha's Vineyard, a Massachusetts island, in 2013.

"These aggregations are a known but not commonly seen basking shark behaviour," the post said.

"Their function still remains a mystery, although it is thought that food resources could draw the sharks together, and they then engage in courtship behaviour.

"One thing's certain: It's a really cool sight."

The basking shark is a filter feeder that consumes plankton. Adults typically reach lengths of 7.9 metres.

The species is found in arctic and temperate waters.

The largest basking shark ever recorded is said to have been caught in 1851 in Canada; it measured 12.3 metres in length.

PAPACY
Benedict Aide's Tell-all Book Will Expose 'Dark Maneuvers'

January 02, 2023
Associated Press
The body of late Pope Emeritus Benedict XVI laid out in state as Archbishop Georg Gaenswein stands on the right inside St. Peter's Basilica at The Vatican, Jan. 2, 2023.

VATICAN CITY —

Pope Emeritus Benedict XVI's longtime personal secretary has written a tell-all book that his publisher on Monday promised would tell the truth about the "blatant calumnies," "dark maneuvers," mysteries and scandals that sullied the reputation of a pontiff best known for his historic resignation.

Archbishop Georg Gaenswein's Nothing but the Truth: My Life Beside Pope Benedict XVI is being published this month by the Piemme imprint of Italian publishing giant Mondadori, according to a press release.

Benedict died Saturday at age 95 and his body was put on display Monday in St. Peter's Basilica ahead of a Thursday funeral to be celebrated by his successor, Pope Francis.

Gaenswein, a 66-year-old German priest, stood by Benedict's side for nearly three decades, first as an official working for then-Cardinal Joseph Ratzinger in the Congregation for the Doctrine of the Faith, then starting in 2003 as Ratzinger's personal secretary.

Gaenswein followed his boss to the Apostolic Palace as secretary when Ratzinger was elected pope in 2005. And in one of the most memorable images of Benedict's final day as pope Feb. 28, 2013, Gaenswein wept as he accompanied Benedict through the frescoed halls of the Vatican, saying goodbye.

He remained Benedict's gatekeeper, confidant and protector during a decade-long retirement, while also serving until recently as the prefect of Francis' papal household. It was Gaenswein who performed the anointing of the sick last Wednesday, when Benedict's health deteriorated, and it was he who called Francis on Saturday to tell him that Benedict had died.

Pope Benedict XVI's personal secretary George Gaenswein, left, wipes his eye as the Pope delivers his message during his last general audience in St. Peter's Square at the Vatican, Feb. 27, 2013.

According to Piemme, Gaenswein's book contains "a personal testimony about the greatness of a mild man, a fine scholar, a cardinal and a pope who made the history of our time." But it said the book also contained a firsthand account that would correct some "misunderstood" aspects of the pontificate as well as the machinations of the Vatican.

"Today, after the death of the pope emeritus, the time has come for the current prefect of the papal household to tell his own truth about the blatant calumnies and dark maneuvers that have tried in vain to cast shadows on the German pontiff's magisterium and actions," the press release said.

Gaenswein's account would "finally make known the true face of one of the greatest protagonists of recent decades, too often unjustly denigrated by critics as 'Panzerkardinal' or 'God's Rottweiler,'" it said, referring to some common media nicknames for the German known for his conservative, doctrinaire bent.

Specifically, the publisher said Gaenswein would address the "Vatileaks" scandal, in which Benedict's own butler leaked his personal correspondence to a journalist, as well as clergy sex abuse scandals and one of the enduring mysteries of the Vatican, the 1983 disappearance of the 15-year-old daughter of a Vatican employee, Emanuela Orlandi.

The book appears to be just part of what is shaping up as a postmortem media blitz by Gaenswein, including the release Monday of excerpts of a lengthy interview he granted Italian state RAI television last month that is to be broadcast Thursday after the funeral.

According to the excerpts published by La Repubblica newspaper, Gaenswein recounted how he tried to dissuade Benedict from resigning after the then-pope told him in late September 2012 that he had made up his mind. That was six months after Benedict took a nighttime fall during a visit to Mexico and determined he no longer could handle the rigors of the job.

"He told me: 'You can imagine I have thought long and hard about this, I've reflected, I've prayed, I've struggled. And now I'm communicating to you that a decision has been taken, it's not up for discussion,'" Gaenswein recalled Benedict saying.

Gaenswein also referred to the struggles, scandals and problems Benedict faced during his eight-year pontificate, recalling he had asked for prayers at the start to protect him from the "wolves" who were out to get him. Gaenswein cited in particular the "Vatileaks" betrayal, which resulted in the butler being convicted by the Vatican tribunal, only to be pardoned by the pope two months before his resignation.

"Anyone who thinks there can be a calm papacy has got the wrong profession," he said.

Protest, love, art: The unusual uses of blood in India

Aspirants for jobs in the armed forces show a letter to the government written in blood in April
By Soutik Biswas
India correspondent

For more than a decade, a non-profit organisation in India has been creating paintings using blood donated by its members.

More than 250 such artworks honouring revolutionaries and martyrs have been made by the Delhi-based Shaheed Smriti Chetna Samiti (Society to Awaken Remembrance of the Martyrs). They are usually given away to ashrams (spiritual retreats) and small museums and displayed in exhibitions.

"Blood is rich in symbolism. We make our paintings in blood to instil patriotism among people. Love for the country is diminishing among children," Prem Kumar Shukla, who heads the non-profit group, told me.

Its founder, Ravi Chander Gupta, a retired school principal, donated blood for 100 paintings until his health began failing. "I started this to attract the public and get their attention. People are more interested if the portraits are in blood. Blood creates sentiments," Gupta, who died in 2017, once told interviewers.

Mr Shukla, his successor, is a doughty 50-year-old school teacher and poet. He claims to have donated blood for 100 paintings alone. Donors like him go to a local lab where their blood is extracted, mixed with anti-coagulants - human blood becomes sticky when its clots - put into 50ml bottles, and given to a bunch of artists. Usually 100ml of blood is enough to make two to three paintings, Mr Shukla says. "I donate blood four times a year for our paintings."

The "blood paintings", says Mr Shukla, were inspired by the persuasive rhetoric - "give me blood and I will give you freedom" - of independence hero Subhas Chandra Bose, known as "Netaji" (respected leader). Bose raised an army of Indian soldiers to fight the British.

The politics of blood runs deep in India. Mahatma Gandhi endlessly monitored his blood pressure and had a "preoccupation with blood", write Jacob Copeman and Dwaipayan Banerjee in Hematologies, a book which examines the connections between blood and politics.

Blood was also an anti-colonial metaphor. Gandhi, the world's most famous pacifist, hoped Indians would "possess blood that could withstand the corruption and poison of colonial violence". A blood-stained cloth worn by the leader on the day he was murdered in 1948 is among the artefacts on display in a museum in Madurai in southern India. "Metaphors of blood - its extraction and sacrifice - are inescapably rife in Indian political discourse," note Mr Copeman and Mr Banerjee.

Not surprisingly blood is a metaphor for loyalty and sacrifice. Ardent supporters of Prime Minister Narendra Modi have drawn his paintings in their blood. Blood is also a mode of protest: In 2013, more than 100 women from villages in Gujarat wrote a letter to Mr Modi in blood, protesting against plans to acquire their land to build a new road. They said they had written postcards, and the prime minister hadn't replied. A teenage girl in Uttar Pradesh state wrote a letter to officials with her blood, seeking justice for her mother who was burnt alive.

Protesters write petitions in blood demanding higher wages, hospitals and schools and opposing laws that they believe are draconian. Some also write love letters in blood to get attention. And people also routinely complain that politicians "suck the people's blood" as a metaphor to highlight issues like corruption and red tape.

In 2008, survivors of the 1984 gas tragedy in Bhopal - the worst industrial accident in India's history - walked 800km (497 miles) to Delhi and sent to then prime minister Manmohan Singh a letter written in their blood to draw his attention to their health and rehabilitation problems.

During demonstrations in the oil-rich state of Assam in 1980, a 22-year-old man used his own blood to write protest slogans on the streets of the capital, Guwahati. "We will give blood, not oil," read one of the slogans.

The street, reported a newspaper, "metamorphosed into a place of pilgrimage where the agitators started lighting earthen lamps, incense sticks and organised devotional prayers".

In 1988, the Communist Party of India (Marxist) asked its supporters to sell their blood to raise money to build a power plant in West Bengal following a funding dispute with the federal government - much of the collected blood had to be eventually destroyed because of lack of storage space, and the plant was completed with a Japanese loan. Around the same time, a group of donors in Kolkata (then Calcutta) sold blood to support a financially impoverished medical institution. (Selling blood was outlawed 10 years later.)

Blood donation camps are organised by political parties to woo voters

Political parties organise blood donation camps to gain public attention. Supporters donate to gain advancement. One blood bank professional told the authors of Hematologies that camps organised by political parties were "terrible because there's no other motivating factor than 'I am trying to please the leader'".

Clearly, blood is a useful symbol. "Blood is associated with purity of caste. Also historically, writing in blood has been a very male thing. Purity related to caste and gender in the form of maleness are the two main forms of social expression in India. Blood is also seen as the highest form of loyalty," says Sanjay Srivastava, a sociologist. In modern-day India, however, women have used blood to break "taboos" around menstruation.

In the end, blood gains you instant attention and recognition.

In 2004, a karate teacher in Chennai (then Madras) painted 57 portraits in his blood of the late Jayaram Jayalalitha, then chief minister of Tamil Nadu state, of which the southern city is the capital.

Shihan Hussaini needed a plot of land for a karate school, and sought an appointment with the chief minister. "She brought me to her residence and promised me a million dollars [for the plot]," Mr Hussaini told the authors of Hematologies. Blood art, he said, was a "tool of propaganda, communication and influencing decision making".

Report: 100-year Coastal Floods in Africa Now Happen Every 40 Years

A new report by the Africa Center for Strategic Studies says "once in a hundred years" floods will become more common in coastal communities due to rising sea levels caused by climate change. As a stretch of West Africa’s coast is set to become the world’s largest megalopolis and an economic powerhouse, academics worry rising sea levels will stymie growth and impact the continent and the world. Henry Wilkins reports from Ganvie, Benin.
