The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Test rocket explosion causes radiation spike in northern Russian city

Test rocket explosion causes radiation spike in northern Russian city, killing two,  https://thenewdaily.com.au/news/world/2019/08/09/rocket-radiation-explosion-russia/?fbclid=IwAR1udqv3rSjTDZE5hZpDHPDo-r7Q-zPhdnuvA-Ejqwu4iButecBmHPW2QdU    Locals have been urged to take iodine tablets and stay indoors after a liquid-propellant rocket engine exploded at a nuclear test site, spiking radiation levels, killing two people and injuring another six.

Greenpeace cited data from the Emergencies Ministry that it said showed radiation levels had risen 20 times above the normal level in Severodvinsk, which is about 30 kilometres from Nyonoksa.

The environmental group said it had appealed to Russia’s consumer watchdog to establish how high radiation had risen, whether it posed a health risk to people and what had actually caused the spike.
According to Norway’s Barents Observer, the explosion happened about 9am on Thursday local time.

The paper reported the site is used for the testing of liquid-fuelled engines of ballistic missiles “for strategic nuclear-powered submarines”.

Authorities in Severodvinsk, which has a population of 185,000, reported the spike, forcing a bay in the White Sea to shut down to shipping.

“A short-term rise in background radiation was recorded at 12 o’clock in Severodvinsk,” Ksenia Yudina said on Thursday local time.   However, Russia’s defence ministry was quoted earlier by state media as saying radiation was normal.

Scientists found evidence that Russia covered up – a major nuclear accident in 2017

A group of scientists called the ‘Ring of 5’ found evidence of a major nuclear accident that went undeclared in Russia, https://www.insider.com/nuclear-accident-unreported-russia-2017-2019-8  

  • In 2017, a group of scientists known as the “Ring of Five” detected “an unprecedented release” of radiation in Europe and Asia.
  • At the time, no country claimed responsibility for the release, but a new study from the Ring of Five attributes it to a nuclear accident at Russia’s Mayak nuclear facility.
  • The facility was previously the site of the 1957 Kyshtym explosion, the world’s third-worst nuclear accident, behind Fukushima and Chernobyl.

A group of scientists called the “Ring of Five” has been scouring Europe’s atmosphere for elevated levels of radiation since the mid ’80s.

In July, the group released a study detailing evidence of an undisclosed nuclear accident that may have taken place less than two years prior. The likely culprit, the scientists said, was the Mayak nuclear facility in Russia, which was once the center of the Soviet nuclear-weapons program.

At the time of the alleged accident in 2017, Russian officials said the facility wasn’t the source of the release, even though the nation showed elevated levels of a radioactive isotope called ruthenium-106. Instead, officials in Russia attributed the radiation to an artificial satellite that burned up in the atmosphere.

But the latest Ring of Five study contradicts that account. Continue reading

Barents Observer report on Russian nuclear reactors in the Arctic

Nuclear fuel carrier “Serebryanka” remains inside closed-off waters near missile explosion site, Barents Observer, By Thomas Nilsen. August 09, 2019      “………Barents Observer report 

The Barents Observer has recently published an overview (pdf) listing the increasing number of reactors in the Russian Arctic. The paper is part of Barents Observer’s analytical popular science studies on developments in the Euro-Arctic Region.

According to the list there are 39 nuclear-powered vessels or installations in the Russian Arctic today with a total of 62 reactors. This includes 31 submarines, one surface warship, five icebreakers, two onshore and one floating nuclear power plants.

Looking 15 years ahead, the number of ships, including submarines, and installations powered by reactors is estimated to increase to 74 with a total of 94 reactors, maybe as many as 114. Additional to new icebreakers and submarines already under construction, Russia is brushing dust of older Soviet ideas of utilizing nuclear-power for different kind of Arctic shelf industrial developments, like oil- and gas exploration, mining and research.  “By 2035, the Russian Arctic will be the most nuclearized waters on the planet,” the paper reads.

Also, existing icebreakers and submarines get life-time prolongation. The average age of the Northern Fleet’s nuclear-powered submarines has never been older than today. Several of the submarines built in the 1980s will continue to sail the Barents Sea and under the Arctic ice-cap until the late 2020s.   https://thebarentsobserver.com/en/security/2019/08/severodvinsk-authorities-confirm-mysterious-brief-radiation-spike-after-missile

RUSSIAN naval base is on mysterious lockdown after an accidental missile explosion

What is Putin hiding? Emergency lockdown of Russian base after ‘nuclear missile’ accident, https://www.express.co.uk/news/world/1163716/Russia-latest-news-Putin-military-explosion-nuclear-missile-radiation-leak-world-war-3

A RUSSIAN naval base is on a mysterious month-long lockdown after an accidental missile explosion at the base was linked to a sudden radiation spike in the region. By OLI SMITH, Aug 9, 2019 The world is on alert after a rocket engine explosion on a naval test range in northern Russia was linked to a shock radiation spike. The Kremlin have confirmed the “rocket engine explosion” killed two people and injured six. There are mounting concerns that the explosion took place during the testing of a new nuclear missile.

Local people were reportedly urged to take precautions against radiation.

Adding to the fears, the Archangelsk base where the explosion took place has since been placed on emergency lockdown, with the nearby White Sea also closed.

A Russian expert told the BBC that the Russian Ministry of Defence has refused to disclose the details behind the mysterious lockdown of the base.

Dr Mark Galeotti said the incident was “clearly a bigger issue than the Russians are letting on”.

While the Ministry of Defence has rejected claims of a radiation leak, city officials in nearby Severodvinsk reported a radiation spike between 11:50 and 12:30 before falling and normalising by 14:00.

Dr Galeotti said: “This depot seems to have been used for the testing of one of Russia’s new liquid-propelled nuclear missiles – it is a highly secretive.

“The official response from the Defence Ministry has been ‘nothing to see here, no spike in radiation, no leak in radiation’.

“All we seem to know is the number of dead and injured, and that it was a rocket test. The rest is gossip.”

he Russian expert added: “They have closed off a large swath of the adjoining White Sea to shipping for a month.

“Despite what the Kremlin have said, there must have been some sort of radiation leak – and they want people to not just stay out of harm’s way, but also don’t want people coming to the site with Geiger Counters.

“The Defence Ministry is trying to play this down. It is clearly a bigger issue than they are letting on.”

He went to claim “we know the Russian authorities have a tendency to lie in a crisis situation”, but highlighted in the modern age they are “able to get away with much less”.

Dr Galeotti also suggested that, in his opinion, “this was an accident that clearly involved a nuclear missile , which has led to a radiation leak”.

A woman in Severodvinsk named only Alina told Russian news site lenta.ru: “I work in the hospital where they’re bringing the injured.

“They advise everyone to close their windows and drink iodine, 44 drops per glass of water.”

Children in local kindergartens were taken indoors after the blast and parents were advised not to take them outside in the evening.

Explosion at Russian missile test, kills two, releases spike of radiation

Radiation spike reported after rocket engine explosion during Russian missile test https://www.independent.co.uk/news/world/europe/russia-radiation-spike-explosion-rocket-engine-missile-test-latest-a9046721.html  

Two killed and four injured after blast, defence ministry say, A short-term spike in radiation levels has been recorded after a rocket engine exploded during a test in Russia, regional authorities said.Moscow’s defence ministry said two were killed and four others wounded after the blast at a military shooting range in the northwestern region of Arkhangelsk.

The ministry said there was no release of radioactivity or any toxic substances.

However, Ksenia Yudina, a spokeswoman for the city of Severodvinsk, which has a population of around 185,000, said: “A short-term rise in background radiation was recorded at 12 o’clock in Severodvinsk.”

The defence ministry confirmed six servicemen and civilian engineers were injured, and two died of their injuries. It said the explosion took place during the test of a liquid-propellant rocket engine.

City officials said background radiation levels had fully “normalised”.

An Arkhangelsk port official said the Dvina Bay area of the White Sea would be closed off to shipping for a month following the explosion, the Interfax news agency reported.

The rocket engine explosion occurred at a weapons testing area near the village of Nyonoksa in the Arkhangelsk region, 800 miles north of Moscow, said the Interfax news agency.

Russian media said an area near Nyonoksa is used for tests on weapons including ballistic and cruise missiles used by the navy.

It came two days after 16,500 people were forced to flee their homes when massive blasts rocked an arms depot in Siberia.

Powerful explosions went on for about 16 hours, killing one person and injuring 13.

Putin And Trump are ‘normalising’the increasing numbers, and the use, of nuclear weapons

The more that Putin and Trump revalidate the role of nuclear weapons in strengthening national security, the more they normalise the discourse of nuclear weapons use and embolden calls for nuclear weapon acquisition in other countries. 

A nuclear world in disarray   https://www.aspistrategist.org.au/a-nuclear-world-in-disarray/ 7 Aug 2019, Ramesh Thakur  We are in a uniquely dangerous period in the atomic age. Geopolitical tensions have spiked in Europe, in the Middle East, on the subcontinent and in East Asia. The nuclear arms control architecture is fraying and crumbling, but no negotiations are underway to reduce global nuclear stockpiles.

A hostile international security environment, the proliferation of nuclear weapons and the emergence of new space, cyber and AI technologies have increased the risk of accidental or deliberate use of nuclear weapons. The growing strategic risks and uncertainty in turn fuel the vicious cycle of renewed interest among US allies in a nuclear deterrent as a hedge against receding US primacy and reliability.

At the conclusion of a United Nations conference on 7 July 2017, 122 states parties of the Nuclear Nonproliferation Treaty adopted a new Treaty on the Prohibition of Nuclear Weapons. All nine countries that possess the bomb (China, France, India, Israel, North Korea, Pakistan, Russia, the UK and the US) boycotted the conference and rejected the treaty. They have done their very best since then to invalidate the concerns behind the drive to adopt it.

The 2018 US nuclear posture review will guide the Trump administration’s nuclear decision-making, modernisation, targeting and signalling. With an expansive vision of the role of nuclear weapons, its threefold effect is to enlarge the US nuclear arsenal, lower the threshold for the use of nuclear weapons, and broaden the contingencies in which the threat of nuclear weapons can be wielded as a tool of diplomatic coercion.

The 2015 Iran nuclear deal established a robust dismantlement, transparency, inspections and consequences regime. Last year, President Donald Trump pulled the US out of the agreement and reimposed sanctions on Iran, despite its still being in compliance with its obligations. That put Washington in breach of the multilaterally negotiated and UN-endorsed Joint Comprehensive Plan of Action. Trump’s decision will have reconfirmed North Korea’s belief that the one thing standing between its security and a US attack is the bomb. It has also caused the recent surge in tensions in the Persian Gulf.

On 1 February, Trump decided to suspend US participation in the Intermediate-Range Nuclear Forces  Treaty—an arms control agreement with Russia that contributed to the end of the Cold War and underpinned European strategic stability for three decades. It lapsed on 2 August. Trump has also rebuffed Russian overtures to discuss a five-year extension of New START beyond 2021. His second summit with North Korea’s leader Kim Jong-un in Hanoi in Februarycollapsed without agreement and Pyongyang now seems to be expanding its nuclear arsenal. Still, at least the US and North Korea are engaged in high-level and working-level discussions and the fear of an imminent war has faded.

The altered US nuclear posture will have cascading effects on the arsenals, doctrines and deployments of other nuclear-armed states. On 1 March 2018, Russian President Vladimir Putin boasted of a new array of invincible nuclear weapons that can penetrate any defences anywhere in the world. He noted the US had not heeded Russian warnings when it pulled outof the 1972 anti-ballistic missile treaty in 2002. ‘You didn’t listen to our country then. Listen to us now’, he said. Putin’s language was reminiscent of the Cold War.

After the US–Russian suspensions of the INF Treaty, Putin warned that Russia could place hypersonic nuclear weapons on submarines deployed near US waters to match the time in which US missiles based in Europe could strike Russia. He also warned of a radioactive tsunami that could be triggered in densely populated coastal areas by a new nuclear-powered underwater drone dubbed ‘Poseidon’.

The more that Putin and Trump revalidate the role of nuclear weapons in strengthening national security, the more they normalise the discourse of nuclear weapons use and embolden calls for nuclear weapon acquisition in other countries. In Australia, this debate has been restarted most recently by Hugh White.

Meanwhile, the official newspaper of the People’s Liberation Army has called for China to strengthen its nuclear deterrence and counterstrike capabilities to match the US’s and Russia’s developing nuclear strategies. China is upgrading its relatively small nuclear arsenal. It rejected Germany’s request to save the INF Treaty by agreeing to trilateralise it, emphasising that its warheads in the low hundreds cannot be compared with US and Russian arsenals in the several thousands.

India and Pakistan are enlarging, modernising and upgrading stockpiles, while investing in battlefield tactical nuclear weapons and systems to counter them. The INF Treaty was the first disarmament agreement of the nuclear age. In an unwelcome symmetry, on 26 February we witnessed the first airstrikes by one nuclear-armed state against another, and the two engaged in a deadly dogfight above the skies of Kashmir the next day. Another India–Pakistan war is a question of when, not if.

The US, described by former Canadian disarmament ambassador Paul Meyer as ‘the high priest of nuclear orthodoxy’, has left its allies looking rather foolish. Washington had led them in dismissing the nuclear weapon ban treaty as impracticable virtue-signalling, instead extolling the decades-long efforts at step-by-step measures to advance the cause of nuclear disarmament that had seen global stockpiles plummet by over two-thirds from their Cold War peak.

When unkind critics noted that the only steps that were visible were leading backwards, Washington responded by launching a new initiative on ‘creating the conditions for nuclear disarmament’. Lest some conditions be specified and met, however, Washington suddenly embraced the more nebulous and inherently subjective language of ‘creating an environment for nuclear disarmament’.

During the Cold War, Soviet citizens who kept to the straight path as the communist party veered sharply to the left or right were denounced as ‘deviationists’. For decades, US allies have been singing from the same hymn book, joining it in the insistence that the step-by-step, progressive approach was the only realistic path to nuclear disarmament. Instead of embracing the new orthodoxy from their fallible high priest, they should do a hard-nosed analysis of the merits of the changing risk–reward calculus of integrating more deeply with the nuclear alliance structure or joining the majority of countries in trying to rid the world of nuclear weapons.

The nuclear disasters that we don’t hear about – The Kyshtym Disaster

5 Unknown Nuclear Disasters: Chernobyl Is Far from the Only One, Chernobyl is not the world’s only nuclear disaster, there are plenty of others to keep you up at night., Interesting Engineering, By  

The Kyshtym Disaster

In September 1957, Ozyorsk, Russia was a closed city, built around the Mayak plant which produced plutonium for both nuclear weapons and fuel.

After scrambling to build the Mayak plant between 1945 and 1948, all six of its reactors initially dumped high-level radioactive waste directly into Lake Kyzyltash. When it became contaminated, they moved on to dumping into Lake Karachay, which also became contaminated.

In 1968, the Soviet government disguised the EURT area by creating East Ural Nature Reserve, with access allowed to only authorized personnel. Documents describing the disaster were only declassified in 1989.

On the International Nuclear Event Scale (INES), Kyshtym is rated a 6, making it the third-most serious nuclear accident behind only the Fukushima Daiichi nuclear disaster and the Chernobyl disaster, which are both Level 7

In 1953, workers built a storage facility for liquid nuclear waste, but that waste was being heated by residual decay heat from the nuclear reaction. The coolers around one of the tanks failed, and on September 29, 1957, that tank exploded with the force of between 70 to 100 tons of TNT.

While there were no immediate casualties, the explosion released an estimated 20 MCi (800 PBq) of radioactivity into the air. A plume containing 2 MCi (80 PBq) of radionuclides, primarily caesium-137 and strontium-90, moved toward the northeast and contaminated an area of more than 52,000 square kilometers (20,000 sq miles).

At least 270,000 people lived in that area, which is referred to as the East-Ural Radioactive Trace (EURT).

In an attempt to maintain secrecy, no evacuation was ordered, but a week later, on October 6, 1957, 10,000 people were removed from their homes.

Estimates of the death toll caused by the accident go from 200 to more than 8,000, depending on the study. A 2001 work stated that the accident caused 66 diagnosed cases of chronic radiation syndrome.

Amazingly, it wasn’t until 18 years later, in 1976, that the full scope of the disaster was disclosed by Zhores Medvedev in the publication the New Scientist.

In 1968, the Soviet government disguised the EURT area by creating East Ural Nature Reserve, with access allowed to only authorized personnel. Documents describing the disaster were only declassified in 1989.

The nuclear accidents we don’t hear about – Soviet Submarine K-19

5 Unknown Nuclear Disasters: Chernobyl Is Far from the Only One, Chernobyl is not the world’s only nuclear disaster, there are plenty of others to keep you up at night., Interesting Engineering, By  

Soviet Submarine K-19

K-19 was one of what the Soviets called their Project 658-class submarines, while NATO called them Hotel-class. They were the first generation of nuclear submarines equipped with nuclear ballistic missiles.

Commissioned on April 30, 1961, K-19 was snake bit from the start. On its initial voyage, on July 4, 1961, it was conducting exercises off the coast of Greenland when suddenly, pressure in the reactor’s cooling system dropped to zero due to a leak.

The emergency SCRAM system immediately inserted the control rods, but due to decay heat, the reactor’s temperature rose to 800 degrees C (1,470 degrees F). The accident released steam containing fission products throughout the ship through the ventilation system.

The captain ordered the ship’s engineering crew to fabricate a new cooling system, but this required them to work within the radioactive area. The jury-rigged cooling water system prevented a complete meltdown of the reactor core.

American warships nearby had picked up K-19’s distress call and offered to help, but K-19’s captain, fearful of giving away Soviet military secrets, refused. Instead, K-19 sailed to meet up with a diesel-powered Soviet submarine. The accident had irradiated K-19’s entire crew, as well as the ship and some of her ballistic missiles.

Within a month, all eight members of the ship’s engineering crew died of radiation exposure. They are Boris KorchilovBoris RyzhikovYuriy OrdochkinEvgeny KashenkovSemyon PenkovNicolai SavkinValery Charitonov, and Yuriy Povstyev.

Within the next two years, 15 other sailors died of radiation-related illnesses.

Towed into port, K-19 contaminated a 700 meter (2,300 feet) wide area, and the repair crews who worked on her. Eventually, the Soviet Navy dumped the damaged reactor into the Kara Sea.

The 2002 movie K-19: the Windowmaker, which starred Harrison Ford and Liam Neeson, is based on the K-19 disaster….. https://interestingengineering.com/5-unknown-nuclear-disasters-chernobyl-is-far-from-the-only-one

August 2- The Intermediate-Range Nuclear Forces Treaty expires- new arms race begins

Demise of US-Russian Nuclear Treaty Triggers Warnings, VOA News , By Charles Maynes, July 31, 2019  “………  “Gorbachev and Reagan had the goal of arms reduction and they did not allow themselves to be pushed off track,” Palazhchenko says.

 “[It was] definitely a huge step forward. Two great nations, two nuclear superpowers have finally been able to stop the arms race in at least two categories of nuclear weapons.”

With the agreement, the U.S. and U.S.S.R. formally renounced the development and deployment of ground-launched missiles with a range of 500 to 5,500 kilometers.

Both sides were still armed with enough nuclear weapons to destroy one another — and the rest of the planet. But George Shultz says the INF’s elimination of short- and medium-range arsenals made the world infinitely safer in one critical regard — time……….

the short-range weapons also magnified the risks of what some called a potential “Euroshima.”

Where once the Cold War threat consisted of missiles lobbed across oceans, the new quick delivery missiles incentivized a first strike and immediate response. There was little time to verify whether an attack was real — or a false alarm.

Fear of the superpowers stumbling into nuclear Armageddon gripped the European public. Thousands marched in opposition to the U.S. missiles — a factor that increasingly influenced Washington’s own decision-making.

“We were negotiating not only with the Soviets but the European public,” recalls Shultz. “Who would want a nuclear missile on their soil? It makes you a target.”

Indeed, public opposition in Europe — and a desire to grab the moral high ground — drove President Reagan to embrace a concept called the “Zero Option.”

The idea? That when it came to negotiating over intermediate and short-range nukes, Reagan wouldn’t just push for the U.S. and U.S.S.R. to limit their arsenals. They’d demand both sides give up everything.

Russian proverb

Critical to selling the idea to skeptics were intensive inspections — with Reagan often citing an old Russian proverb: doverai no proverai. Trust but verify.

“The INF treaty contains in it the most clear verification provisions — onsite inspections!” Schultz says. “People said we could never get that but we did.”

Over the next three years, inspectors observed as both sides destroyed their arsenals — over 800 missiles by the U.S. and nearly double that from the Soviet side.

Viktor Litovkin, a military journalist who covered the events for the the Soviet daily Izvestia newspaper, remembers watching as Soviet engineers carried out the treaty’s provisions — destroying missile after missile with tears in the eyes.   ………

INF 1987-2019 (RIP)

Today, the Trump administration argues it is the INF Treaty that has now outlived its use.

Last October, President Donald Trump’s National Security Adviser, John Bolton, traveled to Moscow to deliver the news: The U.S. would leave the INF agreement amid long-standing U.S. accusations that Russia was violating the treaty………..

Russian President Vladimir Putin soon followed suit — announcing that Russia, too, was leaving the pact.

Barring a last-minute reprieve, the INF treaty expires Aug. 2. Both sides have vowed to develop weapons once banned under the INF. 

A new arms race?

All of this has left Europe, once again, the battleground in a potential new arms race — with tomorrow’s weapons promising shorter warning times….. https://www.voanews.com/usa/demise-us-russian-nuclear-treaty-triggers-warnings

New research: 2017 radioactive cloud traced to an unacknowledged nuclear accident in southern Russia

Mysterious Radiation Cloud Over Europe Traced to Secret Russian Nuclear Accident   https://www.livescience.com/66050-radiation-cloud-secret-russian-nuclear-accident.html  By Tom Metcalfe, Live Science Contributor | July 29, 2019 A vast cloud of nuclear radiation that spreadover continental Europe in 2017 has been traced to an unacknowledged nuclear accident in southern Russia, according to an international team of scientists.

The experts say the cloud of radiation detected over Europe in late September 2017 could only have been caused by a nuclear fuel-reprocessing accident at the Mayak Production Association, a nuclear facility in the Chelyabinsk region of the Ural Mountains in Russia, sometime between noon on Sept. 26 and noon on Sept. 27.

Russia confirmed that a cloud of nuclear radiation was detected over the Urals at the time, but the country never acknowledged any responsibility for a radiation leak, nor has it ever admitted that a nuclear accident took place at Mayak in 2017. [Top 10 Greatest Explosions Ever]

The lead author of the new research, nuclear chemist Georg Steinhauser of Leibniz University in Hanover, Germany, said that more than 1,300 atmospheric measurements from around the world showed that between 250 and 400 terabecquerels of radioactive ruthenium-106 had been released during that time.

Ruthenium-106 is a radioactive isotope of ruthenium, meaning that it has a different number of neutrons in its nucleus than the naturally occurring element has. The isotope can be produced as a byproduct during nuclear fission of uranium-235 atoms.

Although the resulting cloud of nuclear radiation was diluted enough that it caused no harm to people beneath it, the total radioactivity was between 30 and 100 times the level of radiation released after the Fukushima accident in Japan in 2011, Steinhauser told Live Science.

The research was published today (July 29) in the journal Proceedings of the National Academy of Sciences.

The cloud of radiation in September 2017 was detected in central and eastern Europe, Asia, the Arabian Peninsula and even the Caribbean.

Only radioactive ruthenium-106 — a byproduct of nuclear fission, with a half-life of 374 days — was detected in the cloud — Steinhauser said.

During the reprocessing of nuclear fuel — when radioactive plutonium and uranium are separated from spent nuclear fuel from nuclear power reactors — ruthenium-106 is typically separated out and placed into long-term storage with other radioactive waste byproducts, he said.

That meant that any massive release of ruthenium could only come from an accident during nuclear fuel reprocessing; and the Mayak facility was one of only a few places in the world that carries out that sort of reprocessing, he said.

Advanced meteorological studies made as part of this new research showed that the radiation cloud could only have come from the Mayak facility in Russia. “They have done a very thorough analysis and they have pinned down Mayak — there is no doubt about it,” he said.

The accident came a little more than 60 years since a nuclear accident at Mayak in 1957 caused one of the largest releases of radiation in the region’s history, second only to the 1986 explosion and fire at the Chernobyl nuclear power plant, which is now in the Ukraine. [Chernobyl Nuclear Disaster 25 Years Later (Infographic)]

In the 1957 accident, known as the Kyshtym disaster after a nearby town, a tank of liquid nuclear waste at the Mayak facility exploded, spreading radioactive particles over the site and causing a radioactive plume of smoke that stretched for hundreds of miles.

The study showed that the 2017 accident at Mayak was unlikely to have been caused by a relatively simple release of radioactive gas, Steinhauser said. Rather, a fire, or even an explosion, might have exposed workers at the plant to harmful levels of radiation, he added.

Russia has not acknowledged that any accident occurred at the Mayak facility, maybe because plutonium is made there for thermonuclear weapons. However, Russia had established a commission to investigate the radioactive cloud, Steinhauser said.

The Russian commission ruled that there was not enough evidence to determine if a nuclear accident was responsible for the cloud. But Steinhauser and his team hope it may look again at this decision in the light of the new research.

“They came to the conclusion that they need more data,” he said. “And so we feel like, okay, now you can have all of our data — but we would like to see yours as well.”

Any information from Russia about an accident at the Mayak facility would help scientists refine their research, instead of having to rely only on measurements of radioactivity from around the world, Steinhauser said.

The international team of scientists involved are keenly interested in learning more about its causes. “When everybody else is concerned, we are almost cheering for joy, because we have something to measure,” he said. “But it is our responsibility to learn from this accident. This is not about blaming Russia, but it is about learning our lessons,” he said.

The often forgotten nuclear disaster in Russia’s Ural Mountains

River of radiation: Life in the area of the world’s 3rd-worst nuclear disaster  Rt.com  28 Jul, 2019 Before Fukushima and Chernobyl, the worst-ever nuclear disaster was a massive leak from a plant in the eastern Urals. RT went to see how people live in areas affected by the fallout from the USSR’s risky rush to the nuclear bomb.

Chernobyl and Fukushima are the two names that are most likely to come to mind when one thinks about nuclear disaster, and rightfully so. People in the US will likely recall the Three Mile Island accident, while Britons may say the “Windscale fire.”

The name “Kyshtym” will probably mean nothing to the wider public, despite it belonging to the third-worst nuclear accident in history. An RT Russian correspondent traveled to the area to speak with locals, some of whom personally witnessed the 1957 disaster, to find out what living in such a place feels like.

Bomb at any cost

Kyshtym is the name of a small town in what is now Chelyabinsk Region in Russia, located in an area dotted by dozens of small lakes. A 15-minute car ride east will bring you to another town called Ozyorsk. Six decades ago, you wouldn’t find it on any publicly available map because it hosted a crucial element of the Soviet Union’s nascent nuclear weapons program, the Mayak plant.

The Soviet leadership considered building up a stockpile of weapons-grade plutonium to be a high priority, while environmental and safety concerns came as an afterthought. Some of the less-dangerous radioactive waste from Mayak was simply dumped into the Techa River, while the more-dangerous materials were stored in massive underground tanks.

The sealed steel containers, reinforced with meter-thick concrete outer walls, were considered strong enough to withstand pretty much anything. In September 1957 this assumption was proven wrong, when one of the tanks exploded with an estimated power of 70-100 tons of TNT. This happened due to an unrepaired cooling system, which allowed radioactive waste to build heat and partially dry up, forming a layer of explosives, an investigation later found. An accidental spark was then enough to blow off the 160-ton lid of the tank, damage nearby waste storages, and shatter every window pane within a 3km radius.

A plume of radioactive waste was ejected high into the air. Some 90 percent of the material fell right back, contaminating the area and adding to the pollution in the Techa River, but some was atomized and traveled northeast with the wind. A 300km long, 10km wide stretch of land running through three Russian regions is what’s left by the fallout. The worst-affected part of it was designated a natural reserve a few years after the disaster.

Cover up

The disaster was covered up in the Soviet media, which reported that the strange lights in the night sky – actually a glow caused by ionization from radioactive waste – was a rare event related to the aurora. The locals knew something was wrong, of course, due to the evacuation of two dozen nearby villages and the large-scale decontamination work that was to be carried out over the next several years.

Later, the military came to get radiation readings in it. Afterwards, soldiers demolished the banya and took away not only the house but even the layer of soil on which it was built.

Officially, the scale of the disaster remained a state secret until the late 1980s.

Poisoned river

The Techa River remains contaminated now, long after Mayak stopped dumping waste in it. The radiation is relatively low, however: standing next to it is no worse than traveling on an airplane. Thousands of people cross it every day via a bridge road that connects Chelyabinsk and Ekaterinburg – the two nearest provincial capitals.

The only inhabited village down the river is called Brodokalmak and is about 85km downstream from Ozyorsk, and 50km away from the bridge crossing  …….

Ghost village

Halfway between the bridge and Brodokalmak is another village, Muslyumovo. It was inhabited until about a decade ago, when Rostatom, the Russian nuclear monopoly, offered to relocate its 2,500 residents. Now it’s a ghost village………

Triple exposure

Another place that had a close brush with Mayak’s waste is Metlino, a town about 25 minutes east from Ozyorsk. Some residents were unfortunate enough to have been exposed to radiation three times in their lives, according to Lyudmila Krestinina, who heads a lab at a local radiation research medical center.

First, they lived on the Techa River when it was used to dump waste. Then the disaster happened, and the cloud went past, close enough for some fallout but not close enough for it to become a major risk. The third time happened in 1967.

“There was drought and the Karachay bog, where waste was dumped from the Mayak, caught fire. The wind brought radioactive smoke over Metlino,” she said. “Now the contamination level has decreased several times, but it’s still higher than background radiation.”

The bog used to be a lake in the early days of Mayak, which started to dry up in the 1960s. The 1967 incident prompted major landscaping work to cover its shallow parts with earth and provide greater water supply. This solution was ultimately deemed unfeasible, so the rest of the lake was covered as well. The work ended just four years ago. ……. https://www.rt.com/russia/465243-kyshtym-nuclear-disaster-mayak/
