Dominion seeks new 20-year Licensing for Surry Nuclear Reactors Power Engineering 10/17/2018, By Rod Walton Dominion Energy has filed an application with federal regulators asking to keep its Surry nuclear power station licensed for additional 20-year terms.
Surry Units 1 and 2 were commissioned in 1972 and 1973, respectively. Dominion has previously said it believes the nuclear plant along the James River in Virginia could be safely operational through 2053.
Its current licensing allows Units 1 and 2 to provide power through 2032 and 2033. If approved, it would be one of the first 80-year plants in the U.S. Exelon Corp. has also applied for additional 20-year license for its Peach Bottom nuclear generation facility in Pennsylvania. https://www.power-eng.com/articles/2018/10/dominion-seeks-new-20-year-licensing-for-surry-nuclear-reactors.html

The status of “Station Blackout” is a serious one.
“it will be many years before the Japanese people know exactly what happened at Fukushima Daiichi on 11 March 2011. One of the key mysteries was role, if any, the magnitude 9 earthquake played in damaging the plant’s reactor cooling systems. Until lethal levels of radiation inside the reactors fall and workers can carry out comprehensive investigations, the truth about the tremor’s impact will remain a subject of conjecture and contention”
Mr. Takamatsu states with expert authority that the pipes of cooling system ware not designed for the 50 second vibration of the magnitude quake. Barry Brook, kangaroo expert, disagrees and tells the world the quake caused no damage at Fukushima. Yet Mr. Brook must surely know the earthquake caused grid blackout. For reactors are all shut down by earthquakes. A solar plant would have kept generating until the last panel shattered. No one would have been evacuated from such a solar plant.
I submit that Prof. Barry Brook’s description of the effects of earthquake upon the Fukushima Diiachi on 11 March 2011 is totally ignorant of the facts as presented by many qualified experts and fly in the face of the independent commission set up by the Japanese Parliament (Diet). It is confirmed that expert investigators concern aspects of TEPCO’s explanations regarding the quake are “irrational”.
Thus any narrative based upon the nuclear industry view, in line with TEPCO’s may fairly be said to be “irrational”. For the industry view is that there is no possibility of quake damage to any structure or sub structure, such as coolant pipes and valves.
Earthquake Damage At Fukushima – is Industry’s Narrative Truthful or Certain? Nuclear History, 16 Oct 18 I am again going to contrast the statements made by Barry Brook in regard to the events and outcomes at Fukushima Daiichi in 2011 with the facts as presented by Mark Willacy. These facts are published in Willacy’s book, “Fukushima – Japan’s tsunami and the inside story of the nuclear meltdowns”, Willacy, M., Pan Macmillan, copyright 2013, Mark Willacy.
However, I will also include information related to the events which were first published and discussed in 2011. ………..
The earthquake generated the tsunami. What else did the earthquake cause?
In this blog I have included posts which give the IAEA considerations for the electrical grids which are connected to nuclear power plants. The IAEA states that the level of engineering and resilience built into such grids may be a significant additional cost for any nation considering generation to nuclear power.
It comes as no surprise then the electrical grid connected to the Fukushima Daiichi NPP failed for two reasons. 1. The earthquake caused all the nuclear reactors connected to the same grid to rapidly shut down. Thus the earthquake caused a blackout due to cessation of electrical generation. 2. The physical grid infrastructure – poles and wires – were damaged by the earthquake. At Fukushima this meant that more than one of the reactors was physically separated from the grid by the earthquake.
It can therefore be seen that the earthquake meant A. Fukushima Diiachi could not generate nuclear electricity as the quake had shut the reactors down. B. The Fukushima Diiachi Nuclear Power Plant was in Station Blackout for one reason: earth quake damage to nuclear infrastructure – the electrical grid. Continue reading →

Council of Europe requests Turkey to consult neighbours for Akkuyu nuclear plant https://ahvalnews.com/council-europe/council-europe-requests-turkey-consult-neighbours-akkuyu-nuclear-plant
The Parliamentary Assembly of the Council of Europe (PACE) expressed on Thursday deep concern at the construction of the Akkuyu nuclear power plant in an earthquake-prone region of Turkey only 85 kilometres from the border with Cyprus.
In a resolution it adopted, the assembly said that Turkey’s first nuclear plant being constructed as a joint Turkish-Russian project is in very close proximity to the other neighbouring countries.
The assembly asked Turkey to join the UN Convention on Environmental Impact Assessment in a Transboundary Context, also known as the Espoo Convention, and to take into account all concerns expressed, including those expressed by Turkish citizens.
The Espoo Convention , adopted in 1991, sets out the obligations of parties to assess the environmental impact of certain activities at an early stage of planning. It also lays down the general obligation of states to notify and consult each other on all major projects under consideration that are likely to have a significant adverse environmental impact across boundaries
The assembly also requested from the Turkish government to consult with neighbouring countries on the construction of the nuclear plant according to the International Convention on Nuclear Safety.
The construction of the Akkuyu nuclear plant located in the southern province of Mersin was kicked off by President Recep Tayyip Erdoğan and his Russian counterpart Vladimir Putin on Apr. 3.
The nuclear plant “raises concerns for a possible impact in terms of safety because such a power plant in this area affects our country much more than the largest part of the Turkish territory,” said the Cypriot government’s spokesman Prodromos Prodromou, following the groundbreaking ceremony in Mersin.
“Turkey did not take into account the grave reservations expressed by various quarters, nor did it heed the European Parliament’s call to terminate the construction plans since this is a seismologically vulnerable area,” he said.
Environmentalists in Turkey are also concerned about the potentially destructive ecological consequences of the Akkuyu nuclear power plant and several organisations form Mersin filed a lawsuit to stop its construction

Workers who trudged through nuke plant contributed to June uranium leak, report says, The Island Packet, BY SAMMY FRETWELL, sfretwell@thestate.com, October 11, 2018
Workers at the Westinghouse nuclear fuel factory for years walked across a plastic liner that was supposed to keep toxic uranium acid from leaking out of the Lower Richland plant.
All that foot traffic eventually weakened the liner, which covered the plant’s concrete floor. And this summer, Westinghouse discovered that a uranium solution had seeped through the liner, eaten a hole in the plant’s floor and trickled into the earth.
Westinghouse wasn’t conducting detailed inspections to find problems in a section of the plant where toxic acid is mixed for production of nuclear fuel rods, the federal inspection report shows. That acidic solution deteriorated concrete after it seeped onto the plant’s floor for a “prolonged” period of time, the report said.
The report said several safety systems, designed to contain leaks, failed. As a result, “hydrofluoric acid solution was spilled’’ on June 16 from a process tank through the floor.
“They were not doing their maintenance inspections correctly or adequately,’’ Tom Vukovinsky, a senior fuel facility inspector with the NRC, said of Westinghouse.
The NRC’s findings add to a series of questions raised this year about how Westinghouse has operated the 550,000-square-foot factory.
Since discovering the uranium solution had leaked through the plant’s floor this summer, residents of the the Lower Richland community near the factory also have learned about other leaks, previously unknown. The NRC acknowledged recently it did not know for years about leaks in 2008 and 2011, which has caused concern among nearby residents. ………https://www.islandpacket.com/news/state/south-carolina/article219825805.html

NRC centre activated ahead of hurricane, WNN 11 October 2018 The US Nuclear Regulatory Commission (NRC) yesterday activated its Atlanta regional incident response centre in anticipation of Hurricane Michael’s landfall in the south-eastern USA. Southern Nuclear reduced power at the Farley nuclear power plant in Alabama as a precautionary measureSouthern Company subsidiary Southern Nuclear, which operates the two-unit Joseph M Farley plant on behalf of owner Alabama Power, announced yesterday it was reducing power for both units as a “precautionary safety measure” to prepare for potential “weather-related conditions” caused by the hurricane. “These proactive steps will allow station personnel to continue monitoring the storm’s progress and take any necessary actions,” the company said.
The NRC said staff at the Atlanta centre were monitoring and maintaining close contact with the Farley site, which was not expected to shut down as hurricane-force winds were not expected at the site.
The Atlanta centre is one of four regional response centres and covers the regulator’s Region II: Alabama, Florida, Georgia, Kentucky, North Carolina, Puerto Rico, South Carolina, Tennessee, Virginia, U.S. Virgin Islands, and West Virginia. Other regional centres are based in Pennsylvania, Illinois and Texas. The Atlanta centre activated last month in advance of Hurricane Florence, which made landfall in North Carolina on 16 September……..
Two units at Duke Energy’s Brunswick nuclear power plant were taken offline on 13 September ahead of Hurricane Florence. Both units had restarted by 21 September. http://www.world-nuclear-news.org/Articles/NRC-centre-activated-ahead-of-hurricane

What causes nuclear waste glass to dissolve? Phys Org, University of Houston October 10th, 2018
Immobilizing nuclear waste in glass logs—a process known as vitrification—is currently used in the United States to safeguard waste from sites associated with defense activities. Some other countries also use the process to capture waste from nuclear power plants.
Researchers know, however, that the glass can begin to dissolve after a long period of time, and the durability of these glass logs remains an active area of research.
Researchers from the University of Houston, the Department of Energy’s Pacific Northwest National Laboratory and the University of Pittsburgh are working on one of the most pressing issues—what causes the glass to begin to deteriorate relatively quickly at some point, potentially releasing radioactive waste at levels exceeding regulatory thresholds?……….”We have long observed from laboratory studies that zeolite formation in glass corrosion tests resulted in an increase in the glass corrosion rate,” said Neeway, a researcher at PNNL. ………
Zeolite P, the zeolite that forms from the glass, is affected by temperature—Rimer said researchers synthesize it in the lab at 100 °C—but they don’t yet know how crystallization proceeds at lower temperatures and they don’t have methods to deter its formation. But controlling temperatures in the geologic formations designated as nuclear waste repositories is not necessarily practical, thus researchers are looking for other factors that might affect crystal growth, including components of the glass. https://phys.org/wire-news/300629772/what-causes-nuclear-waste-glass-to-dissolve.html

First, cooperate on nuclear safety in the Korean Peninsula, The Hill,
BY VIET PHUONG NGUYEN AND NAJMEDIN MESHKATI, OPINION CONTRIBUTORS — 10/06/18 Last month in Pyongyang, South Korean President Moon Jae-in and North Korean leader Kim Jong Un held their third summit in less than a year, concluding with agreements that ranged from security issues to the economy, and even a pledge to make a joint bid for the
2032 Summer Olympics. Yet, despite positive assessments of the summit’s outcome by Presidents Trump and Moon,
many observers remain skeptical about real progress because of the conspicuous lack of a concrete statement by North Korea for denuclearization.
Absent since the restart of dialogue with North Korea is any discussion on inter-Korean nuclear safety cooperation, despite concerns over possible safety risks at the North Korean nuclear complex. Inattention to the facility could have dire consequences for the peninsula: radioactive fallout does not recognize borders.
For example, because of its inability to acquire civil nuclear technology from abroad, North Korea might try to develop its own power reactor from a variation of outdated Soviet designs such as the RBMK-1000 type that resulted in the most catastrophic man-made disaster in history, the 1986 Chernobyl nuclear accident. On the other hand, the possible dismantlement of nuclear facilities such as the Punggye-ri nuclear test site, which contains hazardous material and radioactive elements, could contaminate the surrounding environment and expose North Korean workers if there is improper clean-up.
In addition, as the operator of several fuel cycle facilities, North Korean leaders and experts no doubt would be interested in learning more about Japan’s costly lessons with nuclear safety. Despite having sophisticated industrial capability and arguably high nuclear safety standards, Japan has experienced deadly accidents in fuel cycle facilities — most notably the accident at a fuel fabrication plant in Tokaimura in September 1999, when the mishandling of enriched uranium led to the death of two workers from acute radiation exposure, and permanent injury of another. The accident, attributed to poor safety culture and inadequate regulatory oversight, exposed 436 people to radiation.
Without strict safety practices and adequate protection, North Korea might experience a similar scenario. Furthermore, the country has issues related to emergency response and communication in the event of a nuclear accident because of the secretive nature of its nuclear program. In particular, because North Korea terminated all cooperation with the International Atomic Energy Agency (IAEA) in 2009, it would be difficult for outsiders to learn about any incident and provide support, if necessary. It is equally difficult for North Koreans to improve their safety culture and standards without an adequate, transparent working environment.
Why make nuclear safety an early priority in the high-level diplomatic process with North Korea? The number, pervasiveness and close-to-the-border locations of nuclear facilitates in North Korea are reasons enough.
The significant role of nuclear energy in electricity generation in South Korea, where 24 nuclear power units contribute almost 30 percent of the electricity production, means South Korean experts would have much to share.
Indeed, South Korea has had to overcome its own safety problems, such as the cover-up of a plant blackout at the Kori-1 nuclear power unit in 2012, and the revelation of falsified test results for safety-grade equipment in the same year. Scientists and engineers from these two countries should be enabled to cooperate on nuclear safety by sharing information about their safety practices.
Besides, communication platforms have existed for this kind of engineering diplomacy. Striving for the middle-power status in the region, South Korea has proposed several initiatives aimed at regional integration among Northeast Asian countries; thus, the issue of nuclear safety in North Korea would be a perfect opportunity for Moon to promote a nuclear safety initiative for bilateral cooperation of nuclear safety professionals from the two Koreas. …….. https://thehill.com/opinion/international/409750-first-cooperate-on-nuclear-safety-in-the-korean-peninsula

Hacking nuclear weapons is a global threat https://thehill.com/opinion/international/410472-hacking-nuclear-weapons-is-a-global-threat
BY DAVID KRIEGER, OPINION CONTRIBUTOR — 10/08/18 There are many ways a nuclear attack could be initiated. These include the four “m’s” of malice, madness, mistake and miscalculation. Of these ways of initiating a nuclear attack, only malice could possibly be inhibited by nuclear deterrence (fear of nuclear retaliation).
For example, if a leader doesn’t believe that nuclear retaliation will occur, he or she may not be inhibited from attacking and nuclear deterrence will not be effective.
Madness, mistake and miscalculation all operate independently of nuclear deterrence. These pose great concern for the human future. An insane or suicidal leader could launch his or her nuclear arsenal without concern for retaliation. A mistake could also lead to the launch of a nuclear arsenal without concern for retaliation. Likewise, miscalculation of the intent of a nuclear-armed country could lead to a nuclear launch without concern for retaliation.
A new, and possibly even greater, concern is coming over the horizon. That concern, related to cyberattacks on an enemy’s nuclear systems, could be labelled as “manipulation.” It is emerging due to the growing sophistication of hackers penetrating cyber-security walls in general. It would be disastrous if hackers were able to penetrate the walls protecting nuclear arsenals.
Imagine a cyberattack on a nuclear weapons system that allowed an outside party to launch a country’s nuclear arsenal or a portion of it at another country. This could occur by an outside party, working with or independently of a state, hacking into and activating the launch codes for a country’s nuclear arsenal. Can we be sure that this could not happen to any of the nine current nuclear-armed countries? It would pose a particular danger to those nuclear-armed countries that keep their nuclear arsenals on high-alert status, ready to be fired on extremely short notice, often within minutes of a launch order.
The Royal Institute of International Affairs in the UK, issued a research paper recently noted, “As an example of what is possible, the US is reported to have infiltrated parts of North Korea’s missile systems and caused test failures. Recent cases of cyber-attacks indicate that nuclear weapons systems could also be subject to interference, hacking, and sabotage through the use of malware or viruses, which could infect digital components of a system at any time. Minuteman silos, for example, are believed to be particularly vulnerable to cyber-attacks.”
Even if eight of the nine nuclear-armed countries had adequate cybersecurity, the weakest link could potentially have vulnerabilities that would allow for a cyberattack. It is also probable that new means of penetrating cybersecurity will be developed in the future. It is within the realm of imagination that terrorist groups could have skillsets that would allow them to breach the cybersecurity of one or more nuclear-armed countries, and set in motion a nuclear attack with highly threatening and dangerous consequences.
The gaps in nuclear deterrence theory cannot be filled by throwing money at them, or with more new missiles with larger or smaller warheads. The problem with nuclear deterrence is that it cannot be made effective, and the potential for breaching the cybersecurity of nuclear arsenals only adds to the vulnerabilities and dangers.
The only meaningful response to nuclear weapons is to stigmatize, delegitimize, and ban them. This is exactly what the new Treaty on the Prohibition of Nuclear Weapons seeks to accomplish. This treaty deserves the full support of the world community. As of now, however, it is only receiving the support of the countries without nuclear arms, and is being opposed by the countries possessing nuclear arms and those sheltering under the U.S. nuclear umbrella. This must change, for the benefit of all the world’s people and especially the citizens of the nuclear-armed countries who would likely be the first victims of a nuclear attack.

Was Three a Near-Fukushima Event on the Atlantic During Hurricane Florence? ObRag, Ocean Beach California by MICHAEL STEINBERG on OCTOBER 10, 2018 Nuclear Shutdown News for September 2018 Black Rain PressNuclear Shutdown News chronicles the decline and fall of the nuclear power industry in the US and beyond, and highlights the efforts of those working for a nuclear free future. Here is our September 2018 report.
A Near-Fukushima on the Atlantic?
On September 17 the Raleigh News & Observer reported, “Floods limit access to Duke’s Brunswick nuclear plant: crews us partopotties, cots.”
Did the Atlantic coast have a near-Fukushima event when during September Hurricane Florence made landfall? Utility Duke Energy’s Brunswick two nuclear reactors are located 30 miles south of Wilmington, NC, where the former Category 4 hurricane made landfall as a tropical storm in mid September.
It was reported that “workers are sleeping on cots and using portable toilets because the water is currently shut off and the toilets can’t flush”, and that there was “limited access to the plant, and some workers have been able to leave the site and check up on their homes nearby. After the storm passed some drove to a Walmart in Southport to stock up on provisions.”
Brunswick’s twin reactors started up in the 1940s, and are now approaching their designed operating life, 40 years. They are called boiling water reactors, the same model as the three Fukushima reactors that melted down in 2011, and were built by the same company, General Electric.
US nuclear plants are required to shut down if hurricane force winds, 73 miles per hour or higher, are moving in. Fortunately the winds weren’t quite that strong when Florence hit the East Coast.
Numerous nuke plants in the Carolina and Virginia were in the storm’s path. But only Brunswick reduced power. The “plant declared an ‘Unusual Event,’ the lowest level of nuclear emergency,” according to the News & Observer.
The Nuclear Regulatory Commission reported, “Flooding of roads and downed trees prevented fresh crews from relieving the nearly 300 Duke Energy ‘storm riders’ who had been on site for days. And the blocked roads made it impossible to reach the 10 mile emergency evacuation zone if a higher level emergency is declared”

EDF Energy extends Hunterston B-7 UK nuclear outage until Dec. 1 LONDON (Reuters) 8 Oct 18– EDF Energy has extended an outage at its Hunterston B-7 nuclear reactor in Britain until Dec. 18, it said on Monday.
The reactor, which can produce enough electricity to power more than 800,000 homes, has been offline since March when cracks were found in its core during a routine inspection.
It was initially scheduled to return to service on Nov. 17, but EDF Energy said it had extended the outage to allow the company more time to demonstrate a safety case, needed before Britain’s nuclear regulator will allow the unit to resume service…….. https://uk.reuters.com/article/uk-britain-nuclear/edf-energy-extends-hunterston-b-7-uk-nuclear-outage-until-dec-18-idUKKCN1MI19D

06.10.2018 Pregnant women in the United States could be exposed to ionizing radioactivity from nuclear waste shipped

around the nation, a radioactive waste watchdog told Radio Sputnik’s Loud & Clear this week.
Given the number of shipments of nuclear waste traveling around the country, “Pregnant women and the fetus and the womb should not be exposed to any ionizing radioactivity if it can be avoided. This is going to happen. Given these kinds of shipment numbers — many thousands — there’s going to be exposures to pregnant women in this country,” says Kevin Kamps, radioactive waste specialist at Beyond Nuclear.
Nuclear waste is shipped past Americans all the time without many of us knowing it. Even waste passing by on a train is emitting radioactive particulates, and some of those can have negative consequences over time.
“It’s like an X-ray. It will cause harm,” Kamps said. Nurses often ask patients to wear protective aprons while taking X-rays to minimize exposure to the radiation, since X-rays are technically a carcinogen according to the World Health Organization. Medical News Today has reported that approximately 0.4 percent of cancers in the US are triggered by CT scans. (CT scans use X-rays and computer imagery to generate pictures of the body to help doctors with diagnoses.)
Transporting nuclear waste products is a risky business for public health outside the US, too
“If you have exterior, or external contamination, on the shipment — which has happened hundreds of times in France, 50 times in the US that we know of — those dose rates increase significantly. In France, on average, it was 500 times the permissible [amount of contamination] on one-third of the shipments. In one case it was 3,300 times [the] permissible [amount]. So if that’s one to two chest X-rays per hour, times 3,300 times permissible, that’s 6,600 chest X-rays per hour,” Kamps told Loud & Clear.

Floating Nuclear Power Plants in Northeast Asia? A Daunting Prospect. Weak multilateral architecture, territorial disputes, and natural disaster vulnerability compound the unknowns of Russia’s new energy platform. The Diplomat, By Tom Corben October 05, 2018 Given the controversy of all things nuclear power in the post-Fukushima era, it was no surprise that the April launch of Russia’s first floating nuclear power plant (FNPP), the Akademik Lomonosov, drew polarizing responses immediately (in spite of the fact that its nuclear fuel was only loaded earlier this week). Russia’s state-owned nuclear utility Rosatom, claimed that the Akademik Lomonosov’s safety precautions exceed “all possible threats,” granting it “invincibility against natural disasters,” and highlighted the enhancements to economic development efforts in Russia’s far-flung territories. Conversely, environmental organizations like Greenpeace labeled the Akademik Lomonosov a “nuclear titanic” or “Chernobyl on ice,” a serious risk to the global environmental and human security. Observers ought to regard warily the sensationalist claims of advocates and opponents of FNPPs alike. Even so, it is difficult not to view Rosatom’s “invincibility” claim without incredulity.
Rosatom has previously claimed in safety briefings to the International Atomic Energy Agency (IAEA) that the Akademik Lomonosov could withstand a magnitude-10 earthquake, tsunamis powerful enough to cast the barge ashore, and even the impact of a 10-ton aircraft. However, disasters such as that at Fukushima in March 2011 show the perils of blind faith in the integrity of nuclear technology and existing safety regimes that claim to preclude all possible disaster scenarios, particularly those where consecutive or compounding disaster events may present unforeseen challenges. That the Akademik Lomonosov is essentially the first of its kind (the comparatively small USS Sturgis aside) means that practitioners and observers alike have little historical experience to draw upon in offering completely watertight safety assessments. Commentators have pointed to nuclear-powered carriers and submarines to counter criticisms that seaborne reactors are inherently dangerous, yet several such vessels have sunk in the past, along with their radioactive cargo. There is, however, no precedent for a reactor complex the size of the Akademik Lomonosov’s going down in coastal or blue waters, nor for the sorts of short- or long-term hazards that may result or the responses that may be required.
These unknown risks are particularly accentuated when framed in the Northeast Asian context. Either the Akademik Lomonosov or one of its successors will reportedly head for the seismically-active Kamchatka Peninsula, which lies north of the Kuril Island chain presently disputed by Japan and Russia. The Sanchi oil tanker disaster in January demonstrated that the region’s geopolitical faultlines can complicate multilateral responses to industrial-environmental threats when they occur in or impact upon disputed territories, even when multilateral fora designed to facilitate collective risk management response to ocean-born hazards already exist. As far as FNPPs are concerned, these mechanisms do not presently account for potential radiological crises. In short, Northeast Asian states will need to move quickly and recalibrate existing institutions accordingly if they are to preclude another serious geopolitically-charged, potentially radiological, environmental disaster.
The Akademik Lomonosov features two KLT-40C reactors (variants of the military-grade KLT-40M model used aboard Russian icebreakers), capable of generating 70MWe — enough energy to provide power and desalinated water for between 100,000–200,000 people. These impressive statistics aside, however, neither the KLT-40C model nor Russia’s overall nuclear safety record are entirely reassuring. In May 2011, for example, the Russian icebreaker Taymyr experienced a severe coolant leak, releasing radioactivity into the atmosphere, and needed to be towed into port for urgent repairs — all this despite recent safety upgrades. There are also several cases of Russian nuclear submarines sinking with hundreds of kilos of uranium and/or nuclear-tipped missiles still aboard, most notably the K-159 wreck in the Barents Sea, though what threat these might pose to the local environment remains unknown.
Furthermore, the appeal of FNPPs as a portable baseline power source for developing distant territories could become a significant setback in the event of a crisis of “unforeseeable” circumstances. Remote territories are just that — remote. In the event of a serious crisis, and considering the absence of local Russian nuclear infrastructure, it may take considerable time for a response team to reach the vessel. That would translate into more time for said crisis to spiral further.
Compounding the tyranny of distance is the region’s geological volatility. A magnitude 7.8 earthquake struck the Kamchatka Peninsula last July, while magnitude 8 quakes struck the Kuril Islands in 2006 and 2007, generating 50-foot tsunamis. While none of these instances resulted in major damage, in 1952 a massive earthquake and tsunami killed thousands and wrought destruction on settlements across the peninsula and the Kuril Islands. In fact, recent research has also demonstrated that seismic and volcanic activity in Russia’s Far East poses a serious natural disaster threat to the entire Pacific Rim. As far as the Akademik Lomonosov is concerned, some argue that its flat-bottomed hull design and lack of self-propulsion increases its vulnerabilityto impending or sudden disaster events. With a registered top speed of only 4 miles per hour with the assistance of tugboats, the task of avoiding an oncoming threat would become all the more difficult. For the sake of comparison, nuclear-powered carriers can hit anywhere between 55-92 kilometers (34-57 miles) per hour unassisted.
In a worst case scenario, a damaged or sinking FNPP could pose a regional radiological threat, one quickly compounded should the vessel be cast toward or into disputed territories or those of another state. Events in January suggest that Northeast Asia is unprepared for such an event. A slow response to the Sanchi oil tanker incident saw the burning vessel drift out of recognized Chinese waters and into those adjacent to the disputed Senkaku/Diaoyu Islands, where it eventually sank. Neither Beijing nor Tokyo moved to assume control of clean-up operations because of these geopolitical tensions, yet their inaction ironically saw the corruption of adjacent common fishing grounds.
In response, commentators (including myself) called for the creation of a regional disaster response agreement capable of bypassing competing territorial claims in the interests of containing similar catastrophes in the future…….
The likely arrival of FNPPs in Asia in the future will bring with them unprecedented risks that should not be discounted if states are serious about avoiding, or at least preparing for, an unprecedented radiological crisis of regional proportions. https://thediplomat.com/2018/10/floating-nuclear-power-plants-in-northeast-asia-a-daunting-prospect/

Watchdog warns EDF over weldings at flagship new nuclear plant, Ft.com 4 Oct 18 France’s nuclear regulator has said that EDF’s flagship next-generation nuclear plant at Flamanville might need further work due to faulty weldings which have already delayed the project.
In July, EDF said there would be further delays and cost overruns due to problems with the weldings. It pushed back the loading of nuclear fuel and the target construction costs at the late and over-budget plant. The state-backed energy utility said at the time that out of the 148 inspected welds, 33 had quality deficiencies and would be repaired. It said a further 20 would be reworked “even though they do not have any defects” while for another 10 it would submit a proposal to the ASN to convince the regulator of their safety. Now, the ASN has suggested, subject to further tests, that 8 of those 10 welds may need further work. The regulator said it “invites EDF to begin preparations on possible repair work to the welds concerned,” in a statement on Wednesday.“ASN also considers that the observed discrepancies indicate a failure of the monitoring carried out by EDF on certain activities of the EPR reactor site in Flamanville. It therefore asks EDF to extend the review of the quality of equipment installed on this reactor,”
“ASN also considers that the observed discrepancies indicate a failure of the monitoring carried out by EDF on certain activities of the EPR reactor site in Flamanville. It therefore asks EDF to extend the review of the quality of equipment installed on this reactor,” the ASN added………
