U.N. Supplied Qatar With Tech to ‘Prevent Nuclear Security Incident’ at 2022 World Cup

Washington Free Beacon, Adam Kredo • November 21, 2022,

The United Nations provided Qatar with equipment and training to prevent “a nuclear security incident” from occurring during the 2022 World Cup, according to the U.N.’s nuclear watchdog group.

The International Atomic Energy Agency (IAEA), which works on proliferation issues across the globe, says it has worked with Qatar’s National Committee for the Prohibition of Weapons for the past year “to thwart any attack involving nuclear or other radioactive material.” The announcement comes as jihadist groups like al Qaeda urge its militant followers “wage jihad” against the tournament as Westerners pour into the country……………

The IAEA says that in the lead up to the games, the organization helped Qatar integrate its nuclear security measures into larger plans that could help disrupt a nuclear or radiological attack. This included providing “comprehensive training to national counterparts on developing and implementing nuclear security measures and on responding to nuclear security events and related emergencies.”

The nuclear watchdog lent Qatar more than 120 radiation detecting devices, including personal radiation detectors, portable backpack detectors, and other instruments that can spot things like a dirty bomb, a crude explosive device that includes radioactive materials.

This is “the first time” the IAEA’s Malaysia-based security center provided such equipment to a country hosting a major public event, according to the IAEA……………………….  https://freebeacon.com/national-security/un-supplied-qatar-with-tech-to-prevent-nuclear-security-incident-at-2022-world-cup/

Europe’s biggest nuclear power plant, Zaporizhzhia, is maybe the most dangerous place in the world right now.

The plant is in Russian-occupied Ukraine and has been shelled repeatedly since March.

The situation is carefully monitored by the International Atomic Energy Agency, the U.N.’s
nuclear watchdog agency tasked with making sure nuclear facilities are safe
and atomic material is only used for peaceful purposes.

Its director general, Rafael Mariano Grossi, recently inspected the site. “Well, it’s an
unprecedented thing, really, in so many ways,” Grossi told Lesley Stahl for
this week’s 60 Minutes. “This place is at the front line which makes the
whole thing so volatile and in need of an urgent action.” Before the war
the plant supplied 20% of Ukraine’s power.

It’s now largely idle, but the reactors still need to be constantly cooled down with circulating water. If
they over-heat it could lead to nuclear catastrophe within hours.

Electricity production at Olkiluoto 3 reactor delayed until 2023.

Full-scale electricity production at Olkiluoto 3 reactor delayed until
2023. An investigation into damage to the reactor’s feedwater pumps will
take a number of weeks, with a knock on effect on the schedule for the
beginning of regular electricity production.

Finland’s newest nuclear reactor will remain offline longer than expected, announced its owner on
Monday, pushing back much-needed relief for electricity consumers. Nuclear
power utility Teollisuuden Voima (TVO) has announced that an investigation
into damage at the much-delayed Olkiluoto 3 nuclear reactor’s feedwater
pumps will continue for a number of weeks.

In a press statement, TVO said
that as a result of the ongoing investigation, the schedule for when
regular electricity production will begin at the reactor cannot currently
be estimated.

Shelling of Zaporizhzhia is playing with fire, says UN nuclear chief, as blasts reported

Explosions cause damage at Ukrainian power plant, as Kyiv says it will investigate videos allegedly of surrendering Russians being shot

Guardian, Jennifer Rankin, Mon 21 Nov 2022

The UN nuclear energy watchdog has said the forces behind the shelling of Ukraine’s Zaporizhzhia power plant are “playing with fire”, after a series of explosions shook the facility.

The International Atomic Energy Agency (IAEA), which has experts based at Zaporizhzhia, reported on Sunday that powerful explosions had shaken the area on Saturday night and Sunday. It said its on-site experts saw some of the explosions from their windows.

It reported more than a dozen blasts from apparent shelling, with damage to some buildings, systems and equipment, but “none so far critical for nuclear safety”.

The head of the IAEA, Rafael Grossi, said the news was extremely disturbing and he called the explosions completely unacceptable. “Whoever is behind this, it must stop immediately. As I have said many times before, you’re playing with fire,” he said.

According to the IAEA Twitter account, Grossi renewed his appeal to Ukraine and Russia to agree and implement a nuclear safety and security zone around the plant as soon as possible.

Zaporizhzhia, in south-east Ukraine, is Europe’s largest nuclear power station and has been under Russian control since March, although its Ukrainian staff remain in place to run the facility. It has faced repeated shelling, raising fears of a nuclear disaster. Moscow and Kyiv have blamed each other for the attacks.

The plant’s six Soviet-designed water-cooled reactors are currently shut down, but there is a risk that nuclear fuel could overheat if the power that drives the cooling systems is shut. Shelling has frequently damaged the plant’s power supply.

Russian officials claimed that Ukrainian forces were behind the latest attacks. “They are shelling not only yesterday but also today, they are shelling even now,” an adviser to the head of Russia’s nuclear power operator Rosenergoatom, Renat Karchaa, told the Russian state news agency Tass. He said there had been 15 aerial strikes, including one that hit a storage facility.

Soon after the Russian accusations, Ukraine’s nuclear energy agency, Energoatom, said Russia was responsible for the shelling, which it said had resulted in 12 hits to Zaporizhzhia’s infrastructure. The company said on Telegram that the list of damaged equipment indicated that the attackers “targeted and disabled exactly the infrastructure that was necessary for the restart of 5th and 6th power units” and the restoration of power production for Ukrainian needs……………………………….. https://www.theguardian.com/world/2022/nov/20/shelling-of-zaporizhzhia-is-playing-with-fire-says-un-nuclear-chief-ukraine

Shutdown of UKraine’s Khmelnytskyy Nuclear Power Plant due to military attacks in the region

 Ukraine’s Khmelnytskyy Nuclear Power Plant (KhNPP) lost all access to the
electricity grid yesterday due to military attacks in the country, forcing
it to temporarily rely on diesel generators for back-up power, Director
General Rafael Mariano Grossi of the International Atomic Energy Agency
(IAEA) said today, citing information he had received from Ukrainian
authorities.

The KhNPP’s grid connection was completely lost at 18:35
local time on 15 November, after the site’s four operating power lines
were progressively lost over a two-and-a-half-hour period because of
missile attacks on the country’s energy infrastructure, Ukraine told the
IAEA. During this period, the plant’s two reactors were shut down,
halting their delivery of electricity to households, factories and others.

Reactors at Ukrainian nuclear power plants shut down after Russian strikes

Reuters, Nov 16 (Reuters) – Several reactors at two Ukrainian power plants automatically shut down as a result of Russian missile strikes on Tuesday, President Volodymyr Zelenskiy said, adding that millions of people were left without electricity………..

As a result of the strikes, automation today disabled several nuclear units at two stations – these are calculated consequences, and the enemy knew exactly what he was doing,” Zelenskiy said in his nightly video address……….

Zelenskiy did not say which power plants were affected, but said that strikes hit the capital Kyiv, Lviv, Rivne and Volyn in the west, Kharkiv in the northeast, Kryvyi Rih and Poltava in the centre, Odesa and Mikolaiv in the south and Zhytomyr in the north……………..  https://www.reuters.com/world/europe/reactors-ukrainian-nuclear-power-plants-shut-down-after-russian-strikes-2022-11-16/

UK government to dump European Union nuclear safety laws – a deregulated race to the safety bottom?

Revealed: Fears over Brexit threat to nuclear safety laws, Herald 13th November,

UK GOVERNMENT plans threatening nuclear and radiation safety laws in a “Brexit bonfire” have provoked resistance from regulators and trade unionists, opposition from Scottish ministers, and alarm from campaigners.

The Cabinet Office has published a list of more than 2,400 European Union (EU) laws which are under review as part of the Government’s bid to scrap them. They include 10 key regulations designed to protect the public and workers from nuclear accidents and radiation leaks.
The UK Office for Nuclear Regulation (ORN), which oversees safety at civil and military nuclear sites, told The Ferret it was trying “to preserve the legislative framework” to meet the “highest international standards”.

The trade union Prospect, which represents scientists and engineers in the nuclear industry, accused UK ministers of “trying to weaken or dismantle a regulatory framework that has served the UK well over many decades”.

The Scottish Government attacked Westminster for “rolling back 47 years of protections in a rush to impose a deregulated race to the bottom”.
Campaigners are worried by the dangers of “watering down” nuclear safety law, and demand tougher legal protections.

A bill to remove “retained EU law” was introduced to the UK Parliament by the former business minister, Jacob Rees-Mogg, in September. It contains a “sunset” clause requiring all remaining EU law to be repealed or assimilated by the end of 2023, though this can be extended to 2026.

Among the laws under threat is the 2019 Radiation (Emergency Preparedness and Public Information) Regulations which compel councils and companies to draw up emergency plans to deal with nuclear accidents. According to UK Government guidance in 2015, the regulations are “key” to ensuring that the public is “properly protected”.

Three sets of regulations aimed at protecting workers and the public from the hazards of radiation are also up for review. One “lays down basic safety standards for protection against the dangers arising from exposure to ionising radiation”, the Government said.

Other laws on the UK Government list cover “maximum permitted levels” of radioactivity in food after a nuclear emergency; imports of radioactively contaminated food following the Fukushima nuclear accident in 2011 and the Chernobyl disaster in 1986; and the safety of decommissioning nuclear plants.

The ORN, which regulates the Faslane nuclear base and six other sites in Scotland, is understood to be taking the threat to nuclear safety laws “very seriously”. The six other sites are Chapelcross in Dumfries and Galloway; Dounreay in Caithness; Hunterston A and Hunterston B, both in North Ayrshire, Rosyth in Fife; and Torness in East Lothian

An ONR spokesperson told The Ferret: “We are in discussions with the Government to preserve the legislative framework that allows us to hold the nuclear sector to account consistent with the highest international standards.”

According to the veteran nuclear critic Pete Roche, this meant that the ONR was resisting the UK Government’s plans. “Reading between the lines, it looks as though the ONR is planning to fight any proposals to make drastic changes to nuclear regulation,” he said.

“In recent meetings I have been involved in, ONR representatives have stressed the need to uphold the highest international standards. I can only hope I am not being overly optimistic and that they stick to their guns.”

Prospect argued that the existing regulatory framework worked well at protecting workers and communities. This was vital as old nuclear plants were being decommissioned and new ones built, it said.
“Perhaps the Government should focus on ensuring that existing regulators are properly resourced to do this important work rather than trying to weaken or dismantle a regulatory framework that has served the UK well over many decades,” said Prospect’s senior deputy general secretary, Sue Ferns.

Ferns.
“Tearing up existing regulations for the sake of purportedly ‘taking back control’ does nothing but introduce uncertainty,” she added. “Nuclear is an international industry, there is no value in seeking to craft UK specific legislative variants just for the sake of it.”

The Scottish Government has urged the Scottish Parliament to withhold consent for the “Brexit bonfire” bill. “Ministers fundamentally oppose the Retained EU Law Bill,” said a spokesperson. “This bill puts at risk the high standards people have come to expect from EU membership, rolling back 47 years of protections in a rush to impose a deregulated race to the bottom.”

The 50-strong group of Nuclear Free Local Authorities was “gravely concerned” about the “threat to water down legislation which provides the public or our environment with protection from the operational or legacy risks posed by civil nuclear power”.
The group’s chairman David Blackburn, a Green councillor from Leeds, said: “If European regulations providing protection are to be removed, we will press Government ministers to instead enact equivalent, or preferably stronger, laws into UK domestic legislation.”

The environmental campaigner and former director of Friends of the Earth Scotland, Dr Richard Dixon, thought that the EU gave the public and workers “vital protections” against radiation risks.
“No backsliding at all can be allowed,” he said.
“This has never been more important with the prospect of damage to nuclear reactors or even the use of nuclear weapons in Ukraine.
“Protection of the same strength or better needs to be put in place.”

The UK Department for Business, Energy and Industrial Strategy did not respond to requests for comment. …………. https://www.heraldscotland.com/news/23121029.revealed-fears-brexit-threat-nuclear-safety-laws/

Sizewell C – proposed coastal area is not suitable for nuclear reactors

 Letter: Your leader on Sizewell C ignores a couple of factors that are key
to our local objections. First, the coastline on which Sizewell A and B are
built and Sizewell C is proposed is disintegrating at an increasingly
alarming rate – just two weeks’ ago a building at nearby Thorpeness had
to be demolished due to collapse of the cliffs.

Second, there is insufficient water in Suffolk to build and operate Sizewell C, which was
one of the main reasons the government’s own planning inspectorate
advised against it recently. Water is planned to be found through the
construction of desalination plants – these require huge amounts of
energy, but more importantly the waste salt and other minerals from the
extraction process will be put back into the sea, poisoning the waters
around for miles.

There are other reasons why this is a disastrous
location: it is a site of special scientific interest and an area of
outstanding natural beauty and the prototype for this type of reactor has
yet to be proved at Flamanville – still not operational, years over
schedule and way over budget. Nuclear has moved on since the design of
these reactors. The government should think again.

Stress corrosion continues to trouble the French nuclear fleet

 This week EDF updated its expectations for its nuclear fleet for this
winter, downgrading its output forecasts to 275-285 TWh, compared to the
previous estimate of 280-300 TWh.

The main driver of the downgraded
forecasts is a refusal by the French nuclear regulator, Autorité de
Sȗreté Nucléaire (“ASN”) to allow EDF to re-start number of reactors
with stress corrosion problems, in line with the planned schedule: Cattenom
1 (1.3 GW) will be offline for a further three and a half months until 26
February 2023; Chooz 1 (1.5 GW) will remain closed for about three months
until 29 January 2023; Penly 2 (1.33 GW) will be delayed by more than two
months until 29 January 2023; Cattenom 3 (1.3 GW) will be closed for a
further two and a half months until 26 February 2023. A couple of other
reactors are likely to have minor delays to their re-start schedules.

Finland’s Olkiluoto 3 repairs could take several months – expert

CARL-EMIL WICKSTRÖM, Helsinki, 10 Nov 2022, (Montel) Fixing the cracked feedwater pumps at Finnish nuclear reactor Olkiluoto 3 (1.6 GW) could take several months if the parts need to be manufactured, nuclear expert Juhani Hyvarinen told Montel on Thursday………………

The manufacturing of new impellers would take at least a few months. But changing them does not take long, a few days or maximum a few weeks, including testing.”

The Olkiluoto 3 reactor has been in test production since March but was stopped last month after cracks were found in feedwater pump impellers.

Operator TVO is investigating the issue but has not yet provided estimates of how long the repairs will take or details on part replacements……………………………………….

Risk of further issues?
The reactor’s launch is 13 years beyond schedule already and so the turbine had been idle since being installed over a decade ago.

The risk of further complications remained until the project was complete, said Hyvarinen.

“So far, the common denominator with the issues has been that the turbine facility is a prototype, it is not exactly like the ones used in Germany for decades,” he said…………..

However, the issue may be how the reactor was run, he said, pointing to the frequent ramp ups and down during the commissioning phase.

“Ramping up and down”
“The pumps are not really designed for that and the manufacturer might not have considered there would be so much ramping up and down,” Hyvarinen said.

“The initial problems were on the reactor’s side before moving to the turbine, he noted. “There is a wave of issues from inside of the facility towards the outside”, indicating that if any new issues arose, they would likely be linked to electrical equipment such as generators, he added. https://www.montelnews.com/news/1365685/ol3-repairs-could-take-several-months–expert

Cracks found in feedwater pumps at Finland’s OL3 nuclear plant

by Kerry Hebden, 9 Nov 22

CRACKS of a few centimetres have been identified in all four of the feedwater pumps of the Olkiluoto 3 EPR nuclear power plant in Finland, less than a year after the facility attained first criticality. 

Owned and operated by TVO, the Olkiluoto plant consists of two boiling water reactors, each producing 890 MW of electricity, and a third EPR (Evolutionary Power Reactor), dubbed Unit 3 or OL3. The EPR is a “Generation III+” nuclear reactor, “that benefits from significant technological advances in nuclear and occupational safety”, said Framatome (formerly known as Avera NP), the plant’s main contractor. 

Unit 3 started construction in 2005, however it only began generating electricity in March 2022 after construction was repeatedly delayed. It was expected to begin commercial operation in September, but after the unit’s boron pumps started unexpectedly during a routine shutdown in April, and following the discovery of material in the turbine’s steam reheater that had detached from the steam guide plates in May, the firm pushed back the start date to December.  

Now though, the further damage that has been observed in the inner parts of the feedwater pumps of the OL3 turbine plant, could delay progress further.  

The large feedwater pumps are used to pump water from the feedwater tank into the steam generators. TVO said the cracks detected in the impellers of the pumps have no impact on nuclear safety, but so far the cause of the damage, which is currently being investigated in several different laboratories, has yet to be determined. …………………………….

One of Finland’s two nuclear power plants, the other being the VVER Loviisa plant, the Olkiluoto facility has been plagued by issues for years. Built by Areva NP for a fixed price of €3bn (US$3bn), the firm estimated in 2012 that the full cost of building the OL3 reactor would amount to around €8.5bn due to the frequent setbacks encountered during its construction.  

The delays led to a bitter dispute between Areva and TVO, with each seeking compensation from the other through the International Court of Arbitration – a scenario which resulted in Areva paying hundreds of millions of euros in compensation to TVO. 

Meanwhile the facility’s other reactors have also experienced problems. In July, OL1 was also temporarily shut down due to damaged fuel elements, and in December 2020, the OL2 reactor automatically shut down when a valve failure caused hot water to reach filters in the reactor’s cleaning system. “The plant’s safety systems functioned as planned, and the disturbance did not pose a danger to people or the environment,” TVO said in a statement at the time. 

TVO did have plans to build a fourth unit at the Olkiluoto facility, and in 2008 submitted an environmental impact assessment in preparation of applying for a construction license. However delays to OL3 has led the company to put its plans on hold. https://www.thechemicalengineer.com/news/cracks-found-in-feedwater-pumps-at-finland-s-ol3-nuclear-plant/

‘It can’t go on like this’: Power restored to Ukrainian nuclear plant but situation untenable, says IAEA

External power has been restored to Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) two days after it
experienced a complete blackout amid Russian shelling, the UN’s
International Atomic Energy Agency (IAEA) said on Saturday. Both of the
plant’s external power lines, a 750kV line and a 330kV back-up line, were
repaired on Friday, re-establishing power to the plant’s six reactors by
10pm.

The reactors have been shut down, although reactors 5 and 6 are in
semi-hot shutdown to provide steam to the site, and arrangements are being
made to further heat-up units 5 and 6 to achieve a “hot shutdown”
state. The other four units in Europe’s biggest nuclear plant remain in
cold shutdown. Ukrainian staff have operated the plant under Russian
occupation since March. The IAEA has had four experts embedded among the
Ukrainian staff since 5 September. It rotated a new team in on Thursday.


Last week, shelling damaged the last two high-voltage lines
connecting ZNPP to the country’s grid, putting it in full blackout mode and
necessitating the activation of all 20 of its diesel back-up generators.
The IAEA said the lines were damaged some 50-60 kilometres from the plant
in Ukrainian-controlled territory.

“The repeated power outages all too clearly demonstrate the extremely serious nuclear safety and security
situation this major nuclear power plant is facing,” said IAEA director
general Rafael Mariano Grossi. He continued: “So far, the brave staff of
the Zaporizhzhya Nuclear Power Plant have always managed to maintain the
safe operation of the six units. But it can’t go on like this. I have
repeatedly called for the urgent establishment of a nuclear safety and
security protection zone around the Zaporizhzhya Nuclear Power Plant to
prevent a nuclear accident. We can’t afford to lose any more time. We must
act before it is too late.”

A disaster waiting to happen’: British nuclear-armed sub resurfaces after fire onboard

  https://cnduk.org/a-disaster-waiting-to-happen-british-nuclear-armed-sub-resurfaces-after-fire-onboard/?fbclid=IwAR3t-FcdURBZY22Nmf7daG7zZm1F4OTGwxQEQ8hvq0X6RMAt6N9X6OdUgsE A Royal Navy nuclear-armed submarine had to abandon its mission and resurface, after a fire broke out onboard following an electrical fault. 

The Ministry of Defence said the incident on HMS Victorious happened six weeks ago. The blaze broke out in an electrical component in one of the submarine’s systems but carbon dioxide injectors built into the module extinguished it. However, all crew were scrambled to tackle the fire and look for others and the sub’s commander had to surface the vessel in the North Atlantic. After the fire was contained, Victorious returned to port at Faslane in Scotland.

Victorious is one of Britain’s four Vanguard-class nuclear-armed submarines with one vessel constantly on patrol ready to launch a nuclear strike. The MoD said the sub wasn’t on patrol during the time of the fire and was en route to the US for wargames. 

News of the incident comes after it was revealed in September that another vessel, HMS Vanguard, would remain in dry-dock for the foreseeable future after more technical issues were discovered.  Vanguard has been in deep maintenance since 2015 at a cost of £500 million. The delay has compounded problems for the Royal Navy – whose so-called “Continuous at-Sea Deterrence” is reportedly operating at half capacity. 

Meanwhile, a whistleblower told STV that staff working at Royal Naval Armaments Depot (RNAD) Coulport – the base where Britain’s nuclear weapons are stored – had to be evacuated due to a “serious radiation breach.”

CND General Secretary Kate Hudson said: “The revelations about HMS Victorious further underline the risks that these weapons present – a disaster waiting to happen. The fact that the sub had to surface and expose itself illustrates both how fallible the technology is and how baseless the myth of ‘invisibility’. The news from Coulport reinforces these concerns. Meanwhile, billions of pounds are being pumped into maintaining these vessels and warheads and billions more in developing news ones. It’s time to stop this irresponsible waste before a real tragedy occurs.”

Incident at France’s Civaux nuclear reactor adds to EDFs problems of stress corrosion crackingin nuclear plants

Stress corrosion cracking: Assessing and remedying cracking problem in
nuclear plants. The full extent of stress corrosion cracking at EDF’s
reactors in France has still to be determined. Nonetheless, lower
production as plants are re-examined has come at the worst possible time
for the company.

Electricite de France SA is investigating an incident
during a test at a halted nuclear reactor last week, just as a series of
repairs jeopardize the country’s power-supply security for the coming
winter. The utility had to stop a high-pressure hydraulic test of the
primary circuit of its Civaux 1 reactor on Nov. 2 when steam was released
in a room of the reactor building. The reactor wasn’t loaded with nuclear
fuel, no one was hurt nor contaminated, and no radioactivity has been
detected outside the building, according to EDF.

The impact of the incident, which is unrelated to so-called stress-corrosion cracks that have
undermined the French nuclear giant’s reactor availability, still needs to
be assessed, Regis Clement, EDF’s deputy-head for nuclear production, said
at a news conference in Paris Tuesday.

The corrosion cracks hobbling EDF
reactors this year have put a hole in its finances and made France —
typically an exporter of power to its neighbors — a net importer. That,
combined with Russia’s dwindling gas deliveries, has contributed to a spike
in energy prices across Europe and stoked concerns of shortages in case of
a windless cold snap this winter.

EDF Nuclear Reactor Has Test Incident, Deepening Supply Concerns

EDF Nuclear Reactor Has Test Incident, Deepening Supply Concerns,  https://www.bloomberg.com/news/articles/2022-11-08/edf-nuclear-reactor-has-test-incident-deepening-supply-concerns#xj4y7vzkg By Francois De Beaupuy, November 9, 2022,

Electricite de France SA is investigating an incident during a test at a halted nuclear reactor last week, just as a series of repairs jeopardize the country’s power-supply security for the coming winter.

The utility had to stop a high-pressure hydraulic test of the primary circuit of its Civaux 1 reactor on Nov. 2 when steam was released in a room of the reactor building.

The corrosion cracks hobbling EDF reactors this year have put a hole in its finances and made France — typically an exporter of power to its neighbors — a net importer. That, combined with Russia’s dwindling gas deliveries, has contributed to a spike in energy prices across Europe and stoked concerns of shortages in case of a windless cold snap this winter.           

The French nuclear giant so far is keeping the Jan. 8 restart date for Civaux 1 unchanged. It aims to have about 42 of its 56 reactors online in December as repairs at a dozen sites affected by cracks progress, up from 30 on Tuesday morning, Clement said. That number is due to rise to 46 in January.

At Civaux, where heavy repairs of corrosion cracks have been completed, an inner insulation tube of a pipe used to introduce sensors in the reactor vessel was ejected in a room beneath the reactor during the pressure test, Clement said. That’s because equipment installed specifically for the test phase broke, he said. 

EDF will send a robot in coming days to put the long radioactive tube in a container, he said. Employees will then be able to access the room, close a valve, and assess damage caused by water that’s still flowing into the room and into a special drain, Clement added.

“It’s way too early to say” how that will affect the restart of the reactor, he said.
