Ecological risks of China’s floating nuclear power plants in South China Sea
China plans to power some of its claimed islets with nuclear energy, the U.S. Department of Defense recently told Congress in an annual report on Chinese military activities. Beijing had indicated last year it was planning to install “floating nuclear power stations” that would start operating before 2020, the report says.
That development would bulk up China’s maritime claim after about a decade of land reclamation in parts of the 3.5 million-square-kilometer sea and the sending of military units to some of the artificial islands, analysts say. Rival maritime claimants Brunei, Malaysia, the Philippines, Taiwan and Vietnam lack similar means to electrify their holdings.
“You are literally facilitating increase of physical control of the South China Sea,” said Collin Koh, maritime security research fellow at Nanyang Technological University in Singapore.
“I think the more immediate concerns of anyone, be they claimants, be they non-claimants, is a huge ecological risk, and taking into account that Chinese nuclear energy technology may not necessarily be one of the best in the world,” he said………
Ecological risks
China is unlikely to do an environmental impact study on any nuclear-power barges before installing them, Koh said. A “runaway reactor” could lead to a “major ecological disaster,” he said. The U.S. Defense Department report notes that the sea is prone to typhoons, during which most vessels seek shelter.
Pirates and terrorists at sea could also disrupt a nuclear power barge, said Andrew Yang, secretary-general of the Chinese Council of Advanced Policy Studies think tank.
“It certainly requires a different kind of infrastructure building, because it’s a floating nuclear power plant, never been doing it before, and the maritime conditions (are) putting a lot of potential risks or uncertainty in terms of maintaining such an installation,” Yang said. https://www.voanews.com/a/china-s-floating-nuclear-power-plants-risks-south-china-sea/4551979.html

Safety measures for America’s nuclear weapons complex to be unravelled
Under siege: Safety in the nuclear weapons complex, Bulletin of the Atomic Scientists, By Robert Alvarez, August 30, 2018 The Defense Nuclear Facilities Safety Board—which oversees and reports on safety practices in the US nuclear weapons complex—is under siege. Congress created the board almost 30 years ago to address years of lax safety practices. Now, the Energy Department is seeking to block the board’s access to safety information, excluding the board from overseeing worker protection at dozens of facilities and blocking board staff from interacting with contractors that operate the department’s nuclear sites. At the same time, the board is undergoing an internal crisis that affects staff morale and, ultimately, its critical role in ensuring the safety of the government’s largest high-hazard research and industrial enterprise.
Largely unknown to the general public, the Defense Nuclear Facilities Safety Board is a small organization, but it has played a critical role in dragging the US nuclear weapons complex away from decades of operating outside the mainstream of nuclear safety practice. With an annual budget of $31 million, the board oversees safety at 10 Energy Department sites that employ 110,000 people and occupy a land base larger than the states of Delaware and Rhode Island combined. These sites store and handle some of the world largest and potentially most dangerous inventories of nuclear materials. Since its inception the board has been largely responsible, among other things, for:
Removing and safely packaging large amounts of unsafe nuclear explosive materials from several sites.- Reducing explosion and fire hazards, a dominant concern.
- Increasing emergency planning and response to major nuclear accidents.
- Upgrading antiquated safety systems at nuclear facilities.
Despite this record of achievement, the board now faces difficulties that include the actions of some if its own members, who either don’t want or can’t seem to execute its mission. Last year, Sean Sullivan, the acting chairman installed at the request of Senate Republicans, tried to secretly convince the Trump White House to get rid of the board entirely, claiming it was “a relic of the Cold-War era defense-establishment.” Sullivan failed and was compelled to resign after his effort was revealed to the public.
As he attempted to eliminate the safety board, Sullivan also created a “secondary proposal” that would impose deep staffing cuts; outlined in a letter to the Office of Management and Budget, this fallback proposal was meant to go into effect if efforts to terminate the board went nowhere. The new acting chair of the safety board, Bruce Hamilton (also selected by Senate Republicans), unveiled the secondary proposal on August 15. The plan would “restructure by reducing the size of the workforce and relocating most of the technical staff to defense nuclear sites. This restructuring would reduce agency employees by at least 32 percent, down to 82 from the current 120.”
Although the restructuring plan has some positive elements—notably an addition of inspectors in the field—the deep budget and staff cut could disrupt and cripple the safety board’s effectiveness. Contention among board members is a symptom of crisis that has led to a loss of staff morale and high turnover. More than 60 percent of its technical staffers have left in less than the last four years. In May, the inspector general who oversees the safety board reported that it was ranked last by employees of 28 small federal agencies in terms a being a desirable place to work. According to the inspector general, more than a third of the safety staff surveyed in 2017 planned to leave, largely because of a “stark disagreement among board members, on how and when [safety] reporting requirements should be issued.” According to the inspector general, “two board members [Sullivan and Hamilton] routinely disapproved staff reports that included reporting requirements and instead proposed amendments to remove the reporting requirements.”
The restructuring plan cannot be considered in isolation from the Trump administration’s aggressive dismantlement of oversight across the government, especially in light of the Energy Department’s constantly stumbling efforts to build new nuclear weapons at its antiquated facilities. The Congressional Budget Office has estimated that US nuclear weapons laboratories and supporting activities will cost $261 billion over the next three decades. The board’s restructuring plan is expected to begin by October 18 of this year and follows the Trump administration’s playbook of slashing safety oversight in federal agencies, as has happened with the Chemical Safety Board, responsible for investigating industrial chemical accidents. Unless Congress intervenes, the restructuring of the Defense Nuclear Facilities Safety Board will proceed.
Safety and conflict in the nuclear weapons complex. Unlike the commercial nuclear power industry, which consists of a relatively small number of reactor designs, the nuclear weapons complex includes a host of one-of-a-kind facilities, many built 50 to 70-plus years ago. Over the decades, each Energy Department site in the complex has created its own unique culture, shaped by secrecy, isolation, and demands of the Cold War nuclear arms race. Since making the most dangerous weapons in the world involves working with some of the world’s most dangerous materials, the employees in the nuclear weapons complex need a high degree of protection against workplace exposure to radiation and toxic materials. The United States is already paying a stiff price for the harm caused to the workers who made nuclear weapons through the 1980s. To date, 120,599 deceased and sick nuclear weapons workers have been paid $15.37 billion in compensation and medical care.
Via a semi-autonomous subunit known as the National Nuclear Security Administration (NNSA), the Energy Department manages the US nuclear weapons complex in an unusual manner. In the complex, private contractors control at least 10 times more employees than federal managers. And unlike the rest of the government, the Energy Department self-regulates its workplace safety performance, primarily through a system of “orders” that are not on their own legally binding, but rather are enforced as requirements in contracts with private companies. With its origins in what the US Governmental Accountability Office has described as an “undocumented policy of blind faith in its contractor’s performance,” this regime is largely dependent on an honor system, in which contractors are expected to self-report their safety problems. ………
Though the Cold War is long over, the Energy Department’s antiquated, contractor-dominated management system—in which safety goal posts are easily moved behind closed doors—continues to endure and, in some cases, thrive. Without the meaningful oversight of the Defense Nuclear Facilities Safety Board, the nuclear weapons complex will predictably march back to a time, in the no-so-distant past, when public and worker safety was an afterthought—with serious consequences. https://thebulletin.org/2018/08/under-siege-safety-in-the-nuclear-weapons-complex/
A second Hanford radioactive waste tunnel in danger of collapse
Second Hanford radioactive tunnel collapse expected. And it could be more severe, August 28, 2018 RICHLAND, WA
The possible collapse of a second Hanford tunnel storing radioactive waste is both more likely than thought a year ago and the effects potentially more severe, according to Hanford officials.
The risk of failure, based on Department of Energy nuclear safety standards, has increased from “unlikely” to “anticipated,” and the potential severity has been increased from “low” to “moderate,” according to the ranking.
The severity of the possible collapse is still not ranked as “high,” but it would be a significant event with the potential for the airborne release of radioactive particles, said Dan Wood, chief operating officer of the CH2M Hill Plateau Remediation Co., a Hanford contractor.
After the partial collapse in May 2017 of the older of two tunnels storing radioactive waste at Hanford’s PUREX processing plant, an initial structural analysis of the second and longer tunnel was conducted.
The analysis concluded that the second tunnel, built in 1964, needed to be stabilized.
But concerns increased after a video inspection of the interior of the tunnel was done this spring, Wood said. At a hearing Monday night, he explained the risks posed by the nuclear reservation’s second tunnel……..
The first tunnel, which is 360 feet long and stores eight railcars loaded with contaminated equipment, was filled with grout by November 2017. Ecology allowed the grouting under emergency conditions without a public hearing.
A second public hearing is planned at 6:30 p.m. Sept. 5 at the University of Washington Center for Urban Horticulture, 3501 NE 41st St., Seattle. https://www.tri-cityherald.com/news/local/hanford/article217470425.html
Water leak in Japan’s unfinished Rokkasho nuclear reprocessing plant

Japan revises guidelines for earthquake probabilities
New earthquake probability scale https://www3.nhk.or.jp/nhkworld/en/news/20180828_18/ Japanese government officials have revised the chances for earthquakes linked to marine trenches in order to avoid misleading the public. The government’s task force for earthquake research released its assessment of quakes that may hit Japan, along with their probabilities of occurring within 30 years.
Currently, the chances of quakes linked to marine trenches are given in percentages.
But experts fear that such descriptions could cause misunderstandings. People might feel safe living in an area with a small quake possibility figure, such as 0.1 percent or less.
The task force said it has introduced a new 4-rank scale to describe quake probabilities.
The highest rank of 3 means having the biggest chance of a large-scale quake within 30 years– a chance of 26 percent or more. Rank 2 is for areas with the chance of a quake between 3 and 26 percent. The rank of 1 suggests quake probabilities of less than 3 percent. Another rank of X suggests the chances of a quake cannot be calculated due to a lack of data, but an imminent quake cannot be ruled out.
Under the new classification system, possible mega quakes, including along the Nankai Trough off the Pacific coast from central through western Japan, are ranked 3.

A failed test leaves Russia’s ultimate doomsday weapon lost in the Barents Sea
![]()
Russia Seems to Have Lost the Ultimate Doomsday Weapon: A Nuclear-Powered Cruise Missile https://nationalinterest.org/blog/buzz/russia-seems-have-lost-ultimate-doomsday-weapon-nuclear-powered-cruise-missile-29632
Here’s what we know.
– Citing an unnamed U.S. intelligence official, CNBC reports that that Russian military lost one of the four cruise missiles used during tests conducted over the Barents Sea between last November and February, all of which ended in failure.
– While it’s currently unclear which launch resulted in the lost missile, U.S. Air Force nuclear-sniffing WC-135 ‘Constant Phoenix’ aircraft were active in the Barents Sea and Baltic Sea from March to August of this year, with a Russian fighter intercepting one of the aircraft over the Baltic Sea on August 8.
– This missile, one of many doomsday devices touted by Russian President Vladimir Putin’s government during Moscow’s last showcase of new military capabilities, is purportedly capable of loitering as an unmanned second-strike platform that can remain in the air for an extended period of time over a virtually unlimited range.
Frankly, a nuclear-powered cruise missile is a 1950s dream that goes against all logic in a world with hundreds of ICBMs tipped with multiple independently-targetable reentry vehicles, all of which can kill a city.

Pebble-bed nuclear reactors – a safety concern
![]()
Experts voice safety concerns about new pebble-bed nuclear reactors Eurekalert, 23 Aug 18
Researchers advise caution as a commercial-scale nuclear reactor known as HTR-PM prepares to become operational in China. The reactor is a pebble-bed, high-temperature gas-cooled reactor (HTGR), a new design that is ostensibly safer but that researchers in the U.S. and Germany warn does not eliminate the possibility of a serious accident. Their commentary, publishing August 23 in the journal Joule, recommends continued research, additional safety measures, and an extended startup phase that would allow for better monitoring.
“There is no reason for any kind of panic, but nuclear technology has risk in any case,” says first author Rainer Moormann, a nuclear safety researcher based in Germany. “A realistic understanding of those risks is essential, especially for operators, and so we urge caution and a spirit of scientific inquiry in the operation of HTR-PM.”
…….the soon-to-be-operational HTR-PM has been built without the safeguards that nuclear reactors in operation today are usually equipped with: it does not have a high-pressure, leak-tight containment structure to serve as a backup in case of an accidental release of radioactive material. It also does not have a redundant active cooling system.
“No reactor is immune to accidents. The absence of core meltdown accidents does not mean that a dangerous event is not possible,” Moormann says. He and his coauthors, Scott Kemp and Ju Li of the Massachusetts Institute of Technology, argue that with new technology, there is always a higher chance of user error. And prototype HTGRs have surprised their operators in the past by forming localized hot spots in the core and unexpectedly high levels of radioactive dust. The pebble-bed design also produces a larger volume of radioactive waste, which is challenging to store or treat……….
