Navy’s nuclear-powered super submarine ‘Trident’ fixed with super glue
The damage was done at HMNB Devonport in Plymouth during a dry dock renovation and refuel. This work, reportedly started in 2015 and is four year behind the schedule and approximately £300 million over budget

London: In a bizarre incident, employees aboard the UK’s most advanced frontline submarine Trident risked the lives of millions of people by allegedly using superglue to fix broken bolts of a nuclear reactor chamber prompting navy chiefs to order an investigation.
The crucial cooling pipes’ shoddy repairs were revealed after one of the bolt fell off during a routine check of the 16,000-ton HMS Vanguard.
Reports reveal that the bolts had broken due to careless overtightening, but civilian staff of the defence contractor Babcock glued the heads back on rather than alerting the damage to the authorities so that the fractured shafts could be repaired correctly.
The staff reportedly informed authorities about a process of work difficulty, or procedural fault, but avoided talking about the bolts and glue.
The staff reportedly informed authorities about a process of work difficulty, or procedural fault, but avoided talking about the bolts and glue.
The incident came to light after a UK newspaper publisged a detailed report on the grave blunder prompting Defence
Secretary Ben Wallace to call for a meeting and set accountability of the officials once and for all.
According to a Navy source, he was enraged that Babcock, one of the largest defence contractors in the UK, kept the Navy in the dark.
It’s a disgrace, they remarked. Nuclear technology forbids cutting corners. “The rules are the rules. Standards in the nuclear industry are never waived,” he said.
The damage was done at HMNB Devonport in Plymouth during a dry dock renovation and refuel. This work, reportedly started in 2015 and is four year behind the schedule and approximately £300 million over budget.
The sailors of the three remaining Trident 2 nuclear missile subs, HMS Vengeance, HMS Victorious, and HMS Vigilance, have had to endure protracted patrols due to persistent delays.
From 2028, the Dreadnought class will take their place and carry the UK’s nuclear deterrent.
The experts said that the seven bolts that were fixed using Superglue were reportedly preventing a Chernobyl type meltdown by holding the insulated coolant pipes.
They were discovered this month, ahead of the engineers’ scheduled first firing of the reactor at maximum power.
Investigators are still combing through data to determine when it occurred and who was to blame. As part of nuclear safety protocols, employees usually work in pairs.
After the incident, the Ministry of Defence in the UK issued a statement saying: “A fault from work done when HMS Vanguard was in dry dock was detected as part of a planned examination.”
It was reported and rectified right away, ministry said while adding that the Secretary of State also engaged with Babcock’s CEO in order to secure reassurance for future works.
Navy sources however claimed there were “no nuclear safety issues and that the reactor would not have exploded if the damage hadn’t been discovered.
“This is a big trust issue for Babcock and the Royal Navy to tackle,” former sub skipper Cdr. Ryan Ramsay stated, adding that It makes one wonder what else has been done poorly.
“The time strain imposed by falling considerably behind schedule may have induced this behaviour,” he said.
Babcock has multi-billion dollar contracts to overhaul at Devonport and maintain the Astute and Vanguard sub fleets
for the Royal Navy at HMNB Clyde in Scotland.
Any quality-related issue is extremely disappointing, however our own thorough inspection procedures found the problem, said Ramsay, adding that There was no safety or operational impact from the work.
Meanwhile, Rolls Royce which manufactures and maintains the reactors asserted that it was indeed a dereliction of duty on Babcock’s part.
New images from inside Fukushima reactor spark safety worry
Images captured by a robotic probe inside one of the three melted reactors
at Japan’s wrecked Fukushima nuclear power plant showed exposed steel bars
in the main supporting structure and parts of its thick external concrete
wall missing, triggering concerns about its earthquake resistance in case
of another major disaster.
The plant’s operator, Tokyo Electric Power
Company Holdings, has been sending robotic probes inside the Unit 1 primary
containment chamber since last year. The new findings released Tuesday were
from the latest probe conducted at the end of March. An underwater remotely
operated vehicle named ROV-A2 was sent inside the Unit 1 pedestal, a
supporting structure right under the core.
It came back with images seen
for the first time since an earthquake and tsunami crippled the plant 12
years ago. The area inside the pedestal is where traces of the melted fuel
can most likely be found. An approximately five-minute video – part of
39-hour-long images captured by the robot – showed that the 120-centimeter
(3.9-foot) -thick concrete exterior of the pedestal was significantly
damaged near its bottom, exposing the steel reinforcement inside. TEPCO
spokesperson Keisuke Matsuo told reporters Tuesday that the steel
reinforcement is largely intact but the company plans to further analyze
data and images over the next couple of months to find out if and how the
reactor’s earthquake resistance can be improved.
The images of the exposed
steel reinforcement have triggered concerns about the reactor’s safety.

France’s nuclear company planning to extend the life of its creaky old reactors.
Electricite de France SA is reviving studies to boost the longer-term
output of some nuclear reactors as part of a plan to extend the life of its
atomic fleet to at least 60 years.
Europe’s energy crisis and rising power
prices have put such considerations back “on the company’s agenda for
2023,” according to Sylvie Richard, who’s in charge of the
state-controlled utility’s €33 billion ($35.6 billion) spending on
reactor maintenance and retrofit for the period from 2022 through 2028. The
upgrades could boost the output of some EDF reactors by 4% to 5%. If that
proves financially viable and gets approved by the nuclear safety
authority, some of the work would take place beyond 2028, Richard told
reporters at the Saint-Laurent nuclear power station in central France
Thursday.
The French nuclear giant has been tasked by President Emmanuel
Macron to extend the lifetime of its 56 reactors and to build at least six
new ones to help the country reduce its reliance on fossil fuels. However,
EDF has been grappling for more than a year with extended reactor repairs
and outages that have worsened Europe’s energy crunch, while triggering a
record loss at the company.

Ukraine’s Zaporizhzhia power plant: How prepared is Europe for a future nuclear disaster?
It raises the question, too, of whether we should rely on nuclear power at all.
It raises the question, too, of whether we should rely on nuclear power at all.
euro news.next, By Camille Bello 31/03/2023
Russia’s invasion has repeatedly knocked out Ukraine’s electricity grid, causing blackouts at the Zaporizhzhia nuclear plant – Europe’s largest – where a constant power supply is needed to prevent the reactors from overheating.
On March 9, the plant blacked out for the sixth time since the occupation, forcing nuclear engineers to switch to emergency diesel generators to power its essential cooling equipment running.
“Each time we are rolling a dice,” Rafael Mariano Grossi, the director general of the United Nations’ International Atomic Energy Agency (IAEA), warned at the time. “And if we allow this to continue time after time, then one day, our luck will run out”.
On Monday, during a meeting with Ukraine’s president Volodymyr Zelensky, Grossi reiterated the situation “isn’t getting any better” as relentless fighting in the area keeps the facility at risk of a disaster.
The IAEA watchdog has called for a “protection zone” around the plant but has failed to devise terms that would satisfy both Ukraine and Russia.
Grossi told the AP on Tuesday he believed a deal was “close”. However, Zelenskyy, who opposes any plan that would legitimise Russia’s control over the facility, said he was less optimistic a deal was near. “I don’t feel it today,” he said.
Is Zaporizhzhia really at risk?
Nuclear power plants are designed to withstand a wide range of risks, but no operating nuclear power plant has ever been caught up in modern warfare.
Because of the repeated crossfire, Zaporizhzhia’s last reactor was shut down in September as a precautionary measure. But external power is still essential to run critical cooling and other safety systems.
Fears about Zaporizhzhia have exacerbated existing concerns around our lack of preparedness for any nuclear-related incident, laying bare anxieties not necessarily around war-related incidents but about climate change and Europe’s old reactors, for instance.
It raises the question, too, of whether we should rely on nuclear power at all.
March 11 marked the 12-year anniversary of the massive earthquake and tsunami that caused the second-worst nuclear accident in history at the Fukushima Daiichi Nuclear Power Plant in Japan.
The anniversary of the catastrophic meltdown that left 160,000 people displaced and cost the Japanese government over €176 billion, was another reminder of the potential threat of a nuclear spill, but a number of other recent events have also raised the alarm in Europe, not least the war in Ukraine.
‘We are not properly prepared’
Europe’s nuclear power reactors are ageing – they were built on average 36.6 years ago – and recent checkups in France have found cracks in several facilities.
Some energy experts have warned that the extreme weather events brought on by climate change could pose a serious threat to the EU’s 103 nuclear reactors, which account for about one-quarter of the electricity generated in the bloc.
Jan Haverkamp, a senior nuclear energy and energy policy expert for Greenpeace, said the chances of Europe seeing a large accident like Fukushima were now “realistic” and “we should take them into consideration”.
“We are not properly prepared,” he told Euronews Next…………………………………………………….
The maintenance of a nuclear plant depends on a number of factors, such as its design and its supervision history. But there are other factors that come into play, such as error-prone humans, earthquakes, tsunamis, fires, flooding, tornadoes or even in the case of Zaporizhzhia, acts of war…………………………………………………………………………………… more https://www.euronews.com/next/2023/03/31/chernobyl-fukushima-europe-prepared-nuclear-disaster-ukraine-earthquake-meltdown-radiation
IAEA head warns on danger of intensified fighting near Zaporizhzhia nuclear power plant
The head of the United Nations atomic energy commission said on Wednesday
that intensified fighting near Europe’s largest nuclear power plant poses
a threat to the facility’s safety. The increasing combat makes it urgent
to find a way to prevent a catastrophic nuclear accident at the
Zaporizhzhia nuclear power plant, said International Atomic Energy Agency
director general Rafael Mariano Grossi. “It is obvious that this area is
facing perhaps a more dangerous phase,” he said of the facility, which is
in a partially Russian-occupied part of Ukraine. “We have to step up our
efforts to get to some agreement over the protection of the plant.”

Concern about Turkey’s Akkuyu Nuclear Power Plant
https://www.ekathimerini.com/opinion/1207709/nuclear-concern/ 1 Apr 23, The announcement by Turkish President Recep Tayyip Erdogan that nuclear fuel will be loaded into the first power unit of the Akkuyu Nuclear Power Plant on April 27 this year should set the alarm bells ringing in the international community and Western allies in particular.
It must be ensured that the nuclear power plant in Mersin Province, on Turkey’s southern coast, will be used only for peaceful purposes and that the unstable leadership of Greece’s neighbor across the Aegean will not be tempted by its aspirations for the role of regional superpower, developing into an even more threatening risk factor.
The issue should not only concern Greece. https://www.ekathimerini.com/opinion/1207709/nuclear-concern/

UN watchdog ditches Ukrainian nuclear plant safety zone scheme
Politico, BY LOUISE GUILLOT, MARCH 29, 2023
The head of the U.N. nuclear watchdog today abandoned the idea of creating a safety and security zone around the Zaporizhzhia nuclear power plant in southern Ukraine.
Since September, Rafael Mariano Grossi, the director general of the International Atomic Energy Agency, has been pushing Ukraine and Russia to agree on putting the nuclear plant off limits from the ongoing military conflict.
“Initially we have been focusing on the possibility of establishing a well-determined zone around the plant,” he told reporters during a visit at the plant today. “Now the concept is evolving, refocusing more on the protection itself, the things that should be avoided … rather than on territorial aspects which pose certain problems.”…………….
“It is obvious that the situation is not improving,” Grossi said, pointing at increasing military activity in the region.
Grossi added that efforts to reach a deal between Kyiv and Moscow on measures to prevent a nuclear accident are still “a work in progress.” https://www.politico.eu/article/un-watchdog-ditches-ukrainian-nuclear-plant-safety-zone-scheme/
IAEA nuclear safety chief at Ukraine’s Zaporizhzhia nuclear power station
The UN atomic watchdog chief is expected on Wednesday to visit Ukraine’s
Zaporizhzhia nuclear power plant, which is currently held by Russian
forces. There are persistent fears about the safety of the nuclear plant —
Europe’s largest — which is located in the southern Zaporizhzhia region
where there has been frequent shelling since Russian troops invaded. Rafael
Grossi, head of the International Atomic Energy Agency (IAEA), and his
delegation are expected to arrive Wednesday morning and leave by afternoon,
according to the Russian news agency TASS, citing an official with Russia’s
nuclear operator Rosenergoatom. This will be Grossi’s second visit to
Zaporizhzhia since Russia invaded Ukraine in February last year, and he
plans to “assess first-hand the serious nuclear safety and security
situation at the facility”, according to the IAEA.

Russian Factory That Makes Nuclear Missile Engines Catches Fire
News Week, BY ISABEL VAN BRUGEN ON 3/23/23
fire has broken out on the territory of a Russian factory that manufactures equipment for the Russian Army, according to state media reports.
Seven people have been rescued from a burning building and firefighters are still searching for the source of the blaze at the Yaroslavl Motor Plant, in Yaroslavl, Russia, which describes itself on its website as one of Russia’s largest enterprises producing multi-purpose diesel engines, clutches, gearboxes and spare parts.
The Russian Emergencies Ministry was quoted by state-run news agency TASS as saying that fire departments were alerted to the blaze at 1.30 p.m. local time. Photos circulating on social media show plumes of thick black smoke rising into the sky.
According to local media reports, there was an explosion prior to the fire…………………………
Russian blogger and analyst Anatoly Nesmiyan said on his Telegram channel that “something quite serious is on fire” at the factory, though did not elaborate on what that could be. Nesmiyan described the factory as one of the largest manufacturers of engines and gearboxes for equipment belonging to the Russian Army, including engines for Topol-M nuclear missile launchers.
According to the Washington-based Center for Strategic and International Studies, the Topol-M is a Russian solid-fueled intercontinental ballistic missile with a range of 11,000 kilometers (6,835 miles).
The incident is the latest in a string of mysterious fires in Russia since President Vladimir Putin invaded Ukraine on February 24, 2022.
On Monday, a Russian anti-Putin partisan movement called Black Bridge claimed responsibility for last week’s fire at a building used by Russia’s Federal Security Service (FSB) in the southern city of Rostov-on-Don near the Ukraine border. https://www.newsweek.com/russian-factory-fire-nuclear-missile-engines-fire-explosion-1789877
Fears that France’s nuclear safety system may now fail – from Nuclear Transparency Watch, 11 French and European NGOs and 23 members of European Parliament.
The nuclear watchdog organisation Nuclear Transparency Watch wrote an open
letter together with 11 French and European NGOs and 23 Members of the
European Parliament (see the lists below) to the French Ministry of Energy
Transition expressing their concerns about the survival of the quality of
the French nuclear safety system.
This open letter was sent in the context
of the French national debate at the National Assembly regarding a reform
of the French nuclear safety system foreseeing the dismantlement of the
Institute for Radioprotection and nuclear safety (IRSN), which is the
French independent nuclear technical support organisation.
On 15 March, this reform was rejected by the Assembly, in fact this reform was
considered unjustified, not being supported by any kind of safety impact
assessment and also dangerous in the perspective of a rapid development of
nuclear facilities.
As a European network, NTW sees this reform as a
potential threat to the nuclear safety culture in Europe with a risk of
downgrading the safety standards set by the well-recognised independent and
dual French nuclear safety system now in place.

Minnesota nuclear plant shuts down for leak; residents worry
A Minnesota utility has begun shutting down a nuclear power plant near Minneapolis after discovering water containing a low-level of radioactive material was leaking from a pipe for the second time
abc news, By TRISHA AHMED and MATTHEW DALY Associated Press, March 25, 2023
MONTICELLO, Minn. — A Minnesota utility began shutting down a nuclear power plant near Minneapolis on Friday after discovering water containing a low level of radioactive material was leaking from a pipe for the second time. While the utility and health officials say it is not dangerous, the issue has prompted concerns among nearby residents and raised questions about aging pipelines.
Xcel Energy discovered in November that about 400,000 gallons (1.5 million liters) of water containing tritium had leaked. The utility made a temporary fix but learned this week that hundreds more gallons of tritium-laced water leaked, leading to the shutdown decision.
After the plant cools over the next few days, workers will cut out the leaking pipe, which is over 50 years old, said Chris Clark, Xcel Energy’s president. The utility will then have the pipe analyzed in hopes of preventing future leaks, he said……………………..
Edwin Lyman, director of nuclear power safety with the Union of Concerned Scientists, said the fact there was a second tritium leak “shines a light on the problem of maintaining aging pipelines” underground at older nuclear plants…………………..
The utility reported the initial leak to state and federal authorities in late November but didn’t make it widely public until last week, raising questions about transparency and public health issues. State officials said they wanted to wait for more details before sharing information widely. Criticism about the delay played a role in Xcel’s decision to hold a public information session Friday……………………………………..
Tim Judson, executive director of the Nuclear Information and Resource Service, a group that opposes nuclear power, said the second leak “is obviously concerning” and that public worries about possible health risks are exacerbated by the recent toxic train derailment in Ohio, where residents remain concerned about possible health effects despite government pledges that air and water are safe.
“People are seeing what happened in Ohio, and they are distrustful of the government response,’’ Judson said. https://abcnews.go.com/US/wireStory/minnesota-nuclear-plant-shuts-leak-residents-worry-98110848

400,000 gallons of radioactive water leaked from a nuclear plant in Minnesota
AP By STEVE KARNOWSKI 16 Mar 23
ST.. PAUL, Minn. (AP) — Minnesota regulators said Thursday they’re monitoring the cleanup of a leak of 400,000 gallons of radioactive water from Xcel Energy’s Monticello nuclear power plant, and the company said there’s no danger to the public.
………………… While Xcel reported the leak of water containing tritium to state and federal authorities in late November, the spill had not been made public before Thursday. State officials said they waited to get more information before going public with it.
…………………….. The Monticello plant is about 35 miles (55 kilometers) northwest of Minneapolis, upstream from the city on the Mississippi River.
………………. Xcel said it has recovered about 25% of the spilled tritium so far, that recovery efforts will continue and that it will install a permanent solution this spring.
…………… Xcel Energy is considering building above-ground storage tanks to store the contaminated water it recovers, and is considering options for the treatment, reuse, or final disposal of the collected tritium and water. State regulators will review the options the company selects, the MPCA said. https://apnews.com/article/minnesota-xcel-energy-nuclear-radioactive-tritium-leak-c7a12ecb1b203179c5f7fef42bd0a3aa?utm_source=homepage&utm_medium=TopNews&utm_campaign=position_02
Lessons from Chernobyl and Fukushima: Is Europe prepared for another nuclear disaster?
