Fire on Russian nuclear submarine: heroic crew prevented nuclear catastrophe.
Russia’s nuclear submarine disaster will test President Vladimir Putin and his navy. ABC News, By Alexey Muraviev 4 July 19, Russia’s Ministry of Defence has officially acknowledged an incident this week with one of its deep-submergence vehicles (DSV) within Russian territorial waters.
The incident seems to point to one of Russia’s most closely guarded naval assets — the Project 10831 AS-31 (AS-12) Kalitka (Norsub-5), more commonly known as Losharik.
It is named after a popular Soviet cartoon character because of its design specifications — a series of titanium spheres under the hull designed to withstand extreme water pressure.
A secret assignment According to the latest reports, all those killed onboard were assigned to a secret naval unit stationed in St Petersburg, which is responsible for operations of Project 18510 Nel’ma (X-Ray) “autonomous deep-sea stations” — Russia’s official description of the DSV-type platforms — the AS-21 and the AS-35.
However, the declared number of casualties and the seniority of the deceased personnel is unclear. It is assumed the tragedy occurred onboard the AS-12, which has an estimated crew of some 25 officers.
All these special-purpose submarines are assigned to the 29th “deep water” Submarine Division based at the Gadzhievo submarine base on the Kola peninsula.
Formally assigned to the Russian Northern Fleet, the “deep-water” submarine division is under the direct control of the Russian Ministry of Defence’s GUGI Directorate, which oversees covert marine and naval activities ranging from deep-sea oceanographic research to covert testing of advanced sea-based combat systems, to undersea special operations.
Covert trials of a nuclear-armed torpedo? While official word suggests the submarine was undertaking scanning of the seabed in one sector of the Barents Sea, the actual mission being undertaken may be different.It is possible the submarine was taking part in the covert sea trials of the Poseidon sub-sea strategic combat system (a large calibre nuclear torpedo) .
The tragedy would be the first reported large-scale fatality sustained by GUGI’s secret force.
But it cannot be compared with previous disasters involving Russian nuclear-powered submarines such as the RFS Kursk Oscar II class catastrophe back in 2000 or the incident onboard RFS Nerpa Akula IIclass back in 2008.
This disaster has happened within a unit designed specifically to operate in extreme physical environments where the safety and professionalism of the crew is a key to survival and success.
The crew comprises only middle-to-senior rank officers…….
Was a nuclear disaster averted?
It is understood that the fire onboard led to the fatal intoxication of more than half of the crew — about 14 out of some 25 onboard — and serious injuries of another four or five onboard.
Any submariner would concur that a fire onboard a submarine on deployment poses a serious risk. Fire onboard a nuclear-powered submarine is even worse.
While it is unknown what triggered that fatal fire, a mechanical failure or a human error, the fact is clear: the crew, at the cost of their lives, prevented a potentially major environmental disaster if the DSV had sunk to the bottom of the ocean, or exploded…… https://www.abc.net.au/news/2019-07-03/russias-nuclear-submarine-disaster-test-vladimir-putin-navy/11274964
Local fishermen saw the Russian nuclear submarine accident
Fishermen witnessed nuclear submarine drama, The sub quickly surfaced and there were subsequent signs of panic on the deck, the local fishermen say. The accident might have been caused by a gas explosion. Barents Observer, By Atle Staalesen,July 03, 2019
They were out doing illegal fishing and do not want to reveal their names. But the men who late Monday evening were onboard a small local fishing boat off the coast of the Kola Peninsula told news agency SeverPost that they witnessed what appeared as a state of emergency.
Eye witnesses
It happened around 9.30 pm near the Ura Bay, one of the witnesses says.
«We were heading towards Kildin, and then, about half past nine in the evening, a submarine surfaces. Suddenly and completely surfaces. I have never seen anything like it in my life. On the deck, people were running around and making fuss,» he told SeverPost.
The fishermen hid in nearby bay from where they saw that a navy vessel and two tugs quickly arrived on site. Around 11 pm, the vessels accompanied the submarine away from the area. There was no sign of smoke, they say.
Other locals later reported that they saw bodies being taken out of the submarine and to an approaching ship.
A source in the Russian Navy later told SeverPost that the submarine seen by the local fishermen was most likely the «Podmoskovie», the mother vessel of the special purpose submarine «Losharik» (AS-31). The «Podmoskovie» is a rebuilt Delta-IV class submarine designed to carry the much smaller «Losharik».
Sources in the Navy on Tuesday told Russian media that the accident had happened in the «Losharik». …… https://thebarentsobserver.com/en/security/2019/07/fishermen-witnessed-nuclear-submarine-drama
Russia’s nuclear submarine fire: what is known so far
What We Know About Russia’s Deadly Nuclear Sub Fire So Far https://www.themoscowtimes.com/2019/07/03/what-we-know-about-russias-deadly-nuclear-sub-fire-so-far-a66264 3 July 19 Fourteen sailors were killed in a fire on board a Russian Defense Ministry research vessel while carrying out a survey of the sea floor off Russia’s Arctic coast.
President Vladimir Putin has dispatched Defense Minister Sergei Shoigu to Severomorsk, the Russian naval base on the Barents Sea where the submarine is now located, to find out what caused the incident and report back to him.
Here’s what we know so far:
— The incident took place on Monday — nearly a day before the news was released — in Russian territorial waters in the Barents Sea, Shoigu reported to Putin.
— The 14 sailors died of smoke inhalation, Shoigu told Putin late on Tuesday.
— He said the crew extinguished the fire “through their decisive action.”
— A Navy commission has been tasked with investigating the cause of the tragedy and a military branch of Russia’s Investigative Committee has openedan inquiry into the deaths.
— The Defense Ministry had informed Putin of the accident on the day it occurred, Kremlin spokesman Dmitry Peskov said on Wednesday.
The submarine
— Russian officials have not commented on the type of vessel involved in the deadly fire.
— An unnamed source in the security forces told the RBC news website the incident took place on the AS-31, a secretive deep-sea nuclear submarine.
— Launched in 2003, the submarine nicknamed Losharik was designed for research, rescue and special military operations, and can hold up to 25 crew members. — It is made from a series of interconnected spheres, making it stronger than conventional submarine designs and allowing it to resist water pressure at great depths.
— Analysts believe the vessel is a key asset of GUGI, the Defense Ministry’s Main Directorate of Deep-Sea Research, and not part of the Russian Navy. St. Petersburg’s fontanka.ru news website and the Kommersant business daily reported that Losharik’s crew members allegedly belong to a military unit that reports to GUGI.
Casualties
— The Defense Ministry has not released the names of those on board the vessel.
— Putin noted that of the 14 casualties, seven held the rank of captain 1st rank and two had held the Hero of Russia award, the highest military honor issued in the post-Soviet period. — Shoigu confirmed that there were survivors, but did not specify how many. Anonymously sourced reports suggested four to five crew members survived the fire.
— RBC, citing social media, listed four names of possible casualties. They include the son of the military unit leader; a submarine commander who holds captain 1st rank and Hero of Russia; and a second captain 1st rank.
— An Orthodox cathedral in Murmansk, a city north of Severodvinsk, has listed 14 names in its announcement of a service “for the fallen seamen-submariners” on Wednesday evening.
Reactions
— Putin called the incident “a great loss for the [Northern] Fleet, and indeed for the Army.”
— Acting governor of St. Petersburg Alexander Beglov and Murmansk region governor Andrey Chibis expressed their condolences to the victims. — “The Losharik incident will likely have a deep operational impact on [GUGI], given how advanced and relatively few these submarines are,” a former U.S. National Security Council staffer told the Radio Free Europe/Radio Liberty news outlet.
— The United States has allegedly not received requests for assistance from the Russian government, a U.S. 6th Fleet spokesperson told the U.S. Naval Institute’s USNI News website.— Norwegian officials said they had been in touch with their Russian counterparts and were monitoring, but had not detected abnormally high levels of radiation.
— Colleagues around the world, including the U.S., will mourn the loss of 14 Russian sailors because of a “special bond between all submariners,” wroteWashington Examiner columnist Tom Rogan.
Past accidents
— This is the largest accident to take place on a Defense Ministry submarine since 2008, when a freon gas leak on the nuclear-powered submarine Nerpa killed 20 and injured 21.
— In August 2000, the Russian nuclear-powered submarine Kursk sank to the floor of the Barents Sea after two explosions in its bow, killing all 118 men aboard. That accident, soon after Putin took office, focused official attention on the state of the military and its hardware, which had been underfunded and neglected after the collapse of the Soviet Union.
14 Russian Sailors Killed in Fire on Nuclear Sub
14 Russian Sailors Killed in Fire on Nuclear Sub https://www.themoscowtimes.com/2019/07/02/14-russian-sailors-killed-in-fire-on-nuclear-sub-reports-a66257 3 July 19 Fourteen submariners on board a Russian Defense Ministry research vessel were killed in a fire while carrying out a survey of the sea floor off Russia’s Arctic coast, the ministry was quoted as saying by Russian news agencies.
The incident took place on the AS-31 deep-sea nuclear submarine nicknamed Losharik, an unnamed source in the security forces told the RBC news website. Launched in 2003, Losharik was designed for research, rescue and special military operations and can hold up to 25 crew members.
The fire broke out at 8:30 p.m. on Monday, RBC cited its source as saying, nearly a day before the ministry released the news. “On July 1 in Russian territorial waters a fire broke out on board a deep-water scientific research vessel that was studying the marine environment of the world ocean on behalf of the Russian navy,” Interfax cited a ministry statement as saying.
“Fourteen submariners died as the result of smoke inhalation … Work is underway to establish the cause of the incident. The investigation is being conducted by the commander-in-chief of the navy.”
The fire has been extinguished and the submarine is now at the Russian Northern Fleet’s base in Severomorsk on the Barents Sea, Interfax quoted the ministry as saying. The statement as cited by the agencies did not identify the type or model of the underwater vessel.
This is the largest accident to take place on a Defense Ministry submersible since 2008, when a freon gas leak on the nuclear-powered submarine Nerpa killed 20 and injured 21.
In August 2000, the Russian nuclear-powered submarine Kursk sank to the floor of Barents Sea after two explosions in its bow, killing all 118 men aboard.That accident, soon after President Vladimir Putin took office, focused official attention on the state of the military and its hardware, which had been subject to underfunding and neglect after the collapse of the Soviet Union.
Since then, Putin has overseen a massive increase in military funding that has allowed the armed forces to renew their equipment and improve training and morale.
However, accidents have continued to happen as the military, used by the Kremlin to project its growing international muscle, has ramped up its activities and extended into new theatres of operation.
In December 2016, a Russian military plane carrying 92 people, including dozens of Red Army Choir singers, crashed into the Black Sea en route to Syria where Russian forces are deployed. Everyone on board was killed.

UK’s Office for Nuclear Regulation (ONR) has concerns about the security of Sellafield’s plutonium
David Lowry’s Blog 28th June 2019 A week ago the UK national nuclear regulator, the Office for Nuclear Regulation (ONR), released its annual report and accounts to zero media
attention. But embedded in its 164 pages was the following intriguing
revelation:
“Early in the reporting year, a number of security events
required us to apply regulatory attention to several of Sellafield Ltd’s
security investigations.” It then added: ” Appropriate lessons have been
identified and we will continue our regulatory focus on security culture
and on influencing improvements in the security competence of the internal
assurance function.
” Sellafield is a big nuclear site that, inter alia,
holds 140,000 kilogrammes of plutonium. A devastating warhead can be made
with just 5kgs. We cannot afford any serious security events at
Sellafield!

Russia’s nuclear power station for the Arctic- a floating Chernobyl?
Russia plans to tow a nuclear power station to the Arctic. Critics dub it a ‘floating Chernobyl’, By Mary Ilyushina, CNN, June 29, 2019 Murmansk, Russia (CNN)Next month, a floating nuclear power plant called the Akademik Lomonosov will be towed via the Northern Sea Route to its final destination in the Far East, after almost two decades in construction.
Gaps revealed in Scotland’s nuclear convoy crash preparations
Gaps revealed in nuclear convoy crash preparations, A series of shortfalls in Scotland’s emergency arrangements for coping with a nuclear bomb convoy crash have been exposed by a Scottish Government review. The Ferret, Rob Edwards on June 28, 2019
Leaking radioactivity from an accident would put “strains” on the resources for monitoring the contamination of people, food and the environment, it says. Monitoring may be required “at scale” because of the large number of people involved.
The review reveals that the fire service hasn’t finalised its emergency procedures for convoy crashes, the police need to be better briefed and vetted, while the ambulance service is not told about convoy movements.
The emergency services have also failed to properly record the lessons they learn from emergency exercises, it adds.
Convoys comprising up to 20 or more military vehicles transport Trident nuclear warheads by road at least six times a year between the Royal Naval Armaments Depot at Coulport on Loch Long, near Glasgow, and the bomb factory at Burghfield in Berkshire. The warheads have to be regularly maintained at Burghfield.
Though the Ministry of Defence attempts to keep them secret, the convoys are often photographed, filmed and followed on social media. They travel close to major centres of population such as Glasgow, Edinburgh, Newcastle, Manchester and Birmingham.
The Ferret revealed on 23 June 2019 that an emergency exercise in Scotland called Astral Climb in 2016 had suffered communication breakdowns that could have put people at risk.
A report by campaigners in August 2017 warned that Scotland was “wholly unprepared” to deal with an accident or an attack on a convoy. When the issue was raised in the Scottish Parliament in May 2018, Scottish ministers promised to ask the police and fire inspectorates to conduct a review. ……..
According to the review, the hazards from a bomb convoy crash come from the “explosive, radioactive and toxic materials” that are transported. “The explosive hazard is the same as that which is associated with any chemical high explosive,” it said.
“The main radioactive materials are plutonium and uranium. Plutonium and uranium are both toxic and radioactive. The convoy may also contain other toxic (but not radioactive) materials such as beryllium and lithium. Beyond the immediate hazard area, the potential dispersion of airborne plutonium particles represents the dominant radioactive hazard.”The Scottish Government’s review listed five emergency procedures that have still to be “finalised” by the Scottish Fire and Rescue Service, including operational guidance and intelligence sharing. They should be completed “as a matter of priority”, the review concluded.
Police Scotland were criticised for only conducting a “verbal briefing” for officers prior to convoy movements. “There would be merit in considering a more formal process to provide a record of the information given to officers,” the review said.
“We found that Police Scotland uses appropriate measures to secure information but there was a lack of clarity regarding vetting and which staff and officers have access to sensitive information.”
The fire and police services were both upbraided for failing to record the lessons learned from emergency exercises such as Astral Climb in 2016. They were urged to introduce new systems to ensure that that improvements were made. ……….. https://theferret.scot/nuclear-convoy-safety-scotland-review/

Belarus nuclear physicist warns on the unsafety of new nuclear plant
Nuclear physicist about Chernobyl / ENG subs
Professor Heorhi F. Lepin, a physicist, co-chairman of the public association ‘Scientists For A Nuclear-Free Belarus’, who took part in the rectification of the consequences of the Chernobyl disaster, warns the Belarusians against launching the nuclear power plant in Astravets. https://belsat.eu/en/?p=1108658
According to him, the site chosen is no good and even dangerous – once an earthquake happened on the spot; there is an intersection of crust fractures. However, President Alyaksandr Lukashenka called the scientists who are critical of nuclear-power engineering and particularly the Astravets NPP ‘undercover bandits’ and ‘enemies of the people’, Lepin stressed. The Belarusian NPP with two VVER-1200 reactors with a total capacity of 2,400 MW is being built according to the Russian project near Astravets in the Hrodna region. The first power unit is scheduled to be commissioned in 2019, the second one — in 2020. Subscribe to our channels:
Radioactive contamination triggers evacuation at shuttered Dounreay nuclear site in Scotland
Radioactive contamination triggers evacuation at shuttered nuclear site in Scotland, https://www.rt.com/uk/462857-radioactive-contamination-evacuation-scotland/ 28 Jun, 2019 Workers tasked with cleaning the decommissioned Dounreay nuclear facility in northern Scotland were evacuated from the site after “human error” resulted in low-level radioactive contamination, it has been revealed.
After an employee detected the contamination, a further investigation was quickly launched revealing several other “hot-spots” around the facility. Workers were immediately forced to vacate the area and work temporarily suspended, reportedthe Aberdeen-based Press and Journal.
Site managing director Martin Moore told a stakeholder group on Wednesday that the contamination had been “insignificant,” and was a result of a “lack of due diligence in monitoring around one of the barriers.”
It was human error. It shouldn’t have happened and we’re very disappointed that it did.
The incident actually took place on June 7, but it was only revealed to the public on Wednesday. Some people expressed anger that there was no public statement made on the day it occurred, although the Office for Nuclear Regulation was reportedly informed.
Officials from Dounreay Site Restoration Ltd (DSRL), the company tasked with decommissioning the plant, said that the measure had been precautionary and that the public was never in any danger.
There was no risk to members of the public, no increased risk to the workforce and no release to the environment.
DSRL has been working to decommission the site, which was shut down in 1994. Although they are also tasked with ensuring the area is decontaminated and clean of nuclear waste, they have already been censured for a safety violation at the same site in 2014, when a fire caused by employees released radioactivity into the atmosphere. In the wake of that incident, the company promised to “learn lessons” and implement a wide-ranging new safety strategy, which seemingly turned out to have issues as well.
Located in northern Scotland, Dounreay was established in 1955 to test UK nuclear reactor technology and shuttered in the mid-1990s. Barring any further accidents, work is expected to be completed between 2030 and 2033.
The Middle East presents a dangerous nexus of nuclear reactors and violence: military action is still an option
Trump’s new Iran sanctions have put airstrikes on hold — but nuclear risks remainHistory suggests these dark scenarios cannot be dismissed. Even more critical, available measures to reduce these dangers must not be ignored. June 25, 2019, NBC News THINK, By Bennett Ramberg, Former policy analyst at the U.S. State Department’s Bureau of Politico-Military Affairs
The Middle East presents a dangerous nexus of nuclear reactors and violence. It remains the only region where foreign powers have attacked their enemies’ nuclear plants. On Monday, President Donald Trump signed an executive order putting in place what he called “hard-hitting” new sanctions on Iran. Should continuing tensions between Tehran and Washington boil over into intense hostilities, one ominous nuclear policy question cannot be ignored: Will the presence of reactors in an enlarged conflict zone open a Pandora’s box to the first radioactive war in history?
Trump’s national security adviser, John Bolton, wrote in a 2015 New York Times opinion piece that Washington needed to aim for “breaking key links in [Iran’s] nuclear fuel cycle” through military action. (And envisioned Israel playing a role.) That military option became moot when the Obama administration signed the Iran deal. Now that Trump has withdrawn from the agreement, however, military action is again an option — as well as serious consequences should any action go forward.
Consider, for example, if the current tensions escalate to the point that Tehran crosses Washington’s red line, as it has threatened, and expands nuclear materials production, openly breaking the deal struck with the Obama administration and its allies. Would the United States decide the time had come to eliminate Iran’s nuclear enrichment and related facilities?
In the powder keg of the Middle East, would Iran’s mullahs or their Hezbollah proxy then seek to make good on longstanding threats to launch reprisal rockets at Israel’s Dimona weapons reactor, releasing radioactive elements? And would such an attack propel Israel to respond in kind by striking Iran’s much larger Bushehr nuclear power plant?
History suggests these dark scenarios cannot be dismissed. Even more critical, available measures to reduce these dangers must not be ignored……..
Today’s Middle East nuclear reactor profile has become more complex, though. Iran now operates one Russian-designed 1,000-megawatt nuclear power plant at Bushehr and is building two others. In 2020, a new power reactor is scheduled to go online in the United Arab Emirates, where three others are under construction. Saudi Arabia, Jordan and Egypt also now plan power reactors. …..
If a nuclear plant is hit, the results could be radiation hazards never seen in warfare. Several factors complicate risk projections…….
Acknowledging that mutually assured radioactive contamination would result from nuclear reactor attacks should be sobering enough to prompt all across the Middle East to heed the terrible lessons of Chernobyl: Releases of large inventories of radiation into the environment only sow grief that will last generations, benefiting no one. now https://www.nbcnews.com/think/opinion/trump-s-new-iran-sanctions-have-put-air-strikes-hold-ncna1021056
Concerns about the safety of Israel’s aging Dimona nuclear reactor
Israel’s Dimona nuclear reactor isn’t Chernobyl, but does have vulnerabilities A disaster at Israel’s reactor would be far less catastrophic than the 1986 meltdown, but the core is being kept in service far longer than intended, and experts warn that’s risky, Times of Israel, By JUDAH ARI GROSS 24 June 19, The hit television miniseries “Chernobyl” has reminded the world of the ever-present specter of a nuclear catastrophe made possible by the deadly combination of negligence, ignorance and incompetence…….
Rocket attacks aren’t the only threat
In addition to the overt threats posed to the Dimona nuclear reactor by terror groups and enemy nations, as well as by earthquakes and other natural disasters, one of the less-discussed concerns surrounding the core is its advancing age and Israel’s apparent resolve to keep it running regardless, the expert said.
The Dimona nuclear core, which was given to Israel by France and went active in the early 1960s, is one of the oldest still operating in the world.
Originally designed to operate for 40 years, the core is now being pushed to remain in service for twice that, according to the expert.
This is not from frugality or unwillingness on Israel’s part to purchase a new core, but a legal inability or disinclination by the countries that produce these cores to sell one to the Jewish state, as Jerusalem refuses to sign the Treaty on the Non-Proliferation of Nuclear Weapons, which is meant to prevent the spread of nuclear weapons.
As a result of Israel’s inability to replace the nuclear core, it is motivated to keep it in service for as long as possible, the atomic expert said, replacing and upgrading whatever parts it can and carefully monitoring the components it can’t for any possible “show-stopping” signs of trouble, notably in its aluminum reactor tank…….
Despite the government’s assurances, several Israeli nuclear experts — including some of the scientists who founded the Dimona reactor — as well as politicians have for years been calling for the aging core to be shut down over the risks it posed. ……
One of the central issues regarding Dimona’s safety is that it has no independent oversight. Since Israel is a non-signatory of the nuclear non-proliferation treaty, the International Atomic Energy Agency do not inspect the site, nor do American inspectors, who did monitor the reactor in its early days until they determined that their checks were effectively worthless as many aspects of the site were being kept hidden from them. Instead, the reactor is monitored by Israel’s Atomic Energy Commission — the same body that is responsible for running it.
The highly classified nature of the work there also limits the amount of public debate about the nuclear research center……..
This secrecy and lack of independent oversight means Israelis (and to a lesser extent Jordanians) can only hope that the government is doing its all to prevent a nuclear catastrophe — albeit one that would be far smaller than Chernobyl. https://www.timesofisrael.com/israels-dimona-nuclear-reactor-isnt-chernobyl-but-does-have-vulnerabilities/
Production at Australia’s only nuclear reactor facility halted after ‘safety incident’
Two workers exposed to unsafe radiation dose at Lucas Heights nuclear facility, Guardian, Michael McGowan@mmcgowan 24 Jun 2019
Production at Australia’s only nuclear medicine facility halted after ‘safety incident’ Production has ceased and an urgent investigation has been launched after two employees at a newly opened Australian nuclear medicine facility at Lucas Heights were exposed to an unsafe dose of radiation late last week.Just two weeks after it was granted a licence to enter into full domestic production, the Australian Nuclear Science and Technology Organisation (Ansto) has confirmed production at its new $168m nuclear medicine facility has been halted after “a safety incident” on Friday morning.
Ansto said three of its workers were “attended to by radiation protection personnel” after the incident, in which contamination was detected on the outside of a container holding 42 millilitres of the radioisotope molybdenum-99 (Mo-99).
Two of those workers received a radiation dose above the legal limit roughly equivalent to a conventional cancer radiation therapy treatment, an Ansto spokesman said……
Located at the Lucas Heights nuclear facility in Sydney’s south, the $168m nuclear medicine facility was announced by the federal government in 2012 with the goal of tripling Australian production of Mo-99, the parent isotope of Technetium-99m. …..
It is the second contamination scare at the Lucas Heights facility in only a few months.
In March three staff at the Lucas Heights nuclear facility were taken to hospital after they were exposed to sodium hydroxide when a cap came off a pipe in the nuclear medicine manufacturing building. https://www.theguardian.com/australia-news/2019/jun/24/two-workers-exposed-to-unsafe-radiation-dose-at-lucas-heights-nuclear-facility
