November 8, 2022
TOKYO (Kyodo) — Japan’s industry ministry is considering extending the lifespan of nuclear reactors to beyond the current 60 years with ambitions to finalize the plan by the end of the year, in a bid to cut carbon emissions and ensure stable energy supplies threatened by Russia’s war in Ukraine, sources familiar with the matter said Tuesday.
The Ministry of Economy, Trade and Industry is looking to extend the number of years nuclear power stations can remain open by considering screening periods, necessary for stricter plant safety operations, as separate from the total service life, which could allow nuclear reactors to operate for longer. During safety checks, the nuclear plants are not operational.
A ministry panel is set to discuss extending the service life of the nuclear power stations in such a way as a main scenario among other options, with plans to finalize their decision by the end of the year, the sources said.
Under the current safety rules, the Nuclear Regulation Authority limits nuclear reactors’ service period to 40 years in principle. If approved by the regulatory body however, the period can be extended by up to 20 years.
The panel will also look at scrapping the 60-year lifespan, as well as maintaining the current rules as two alternative options, in case the proposal is found not to be viable.
Prime Minister Fumio Kishida said in August that Japan will push ahead with the use of nuclear power, citing the plan as an option to achieve net-zero emissions and secure a stable electricity supply.
Japan relies heavily on fossil fuel imports for power generation, with its energy self-sufficiency rate standing at 12.1 percent as of fiscal 2019, lower than many other developed countries.
Nuclear power plant operators must pass the tougher regulations to restart their reactors after a nationwide halt which occurred after the Fukushima nuclear disaster of March 11, 2011, which was caused by a massive earthquake and tsunami. Only a handful of reactors in Japan have since resumed operations, while the public remains concerned over their safety.
Some utilities face prolonged screening processes by the NRA. More than nine years have passed since the safety examinations of Hokkaido Electric Power Co.’s Tomari nuclear power plant began, for example.
The electric power industry has urged more than 60 years of service will be safe provided appropriate maintenance operations are guaranteed.
The safety watchdog proposed earlier this month that the safety of nuclear plants aged 30 years or older, regardless of whether a reactor lifespan is extended, be checked at least once a decade to obtain approval for their continued operation.

In Suttsu, Japan, residents don’t want nuclear waste
At a time when Japan announces the restart of seventeen nuclear reactors by 2023, the question
of the management of radioactive waste arises. In Suttsu, a landfill project is under study, to the great despair of the inhabitants. “We don’t want our village to become a village of garbage cans”, protest Kazuyuki
Tsuchiya and his wife, Kyoko.
This couple in their seventies runs an inn in Suttsu, located on the island of Hokkaido, in northern Japan. Composed of 78% forest, this village of 2,800 souls, landlocked between mountains and the seaside, is picturesque.
It is here that a nuclear waste storage project has been taking shape since 2020 . The only ones to have applied to the Radioactive Waste Management Company (Numo), created by the Ministry of Economy, Trade and Industry.

NRA risks losing its reputation as neutral nuclear watchdog body
Members of the Nuclear Regulation Authority hold a meeting Nov. 2 in Tokyo’s Minato Ward.
November 5, 2022
The Nuclear Regulation Authority (NRA) has started working on legal revisions to effectively eliminate the limit on the operational life span of nuclear reactors.
The NRA appears to be responding to growing calls for the “revival” of nuclear power generation within the government and the business community. The NRA was set up as a highly independent nuclear safety watchdog in line with lessons gleaned from the 2011 Fukushima nuclear disaster. It should not forget its original mission.
The legal life span of a nuclear reactor is 40 years in principle but can be extended to 60 years at a maximum.
But the Ministry of Economy, Trade and Industry (METI), acting at Prime Minister Fumio Kishida’s behest, has proposed increasing the life span of reactors. Acting in tandem with the government’s move, the NRA instructed its Secretariat, a government agency, to review the current rules.
In a recent meeting on this issue, the NRA Secretariat presented a proposal which would require reactors that have been in service for 30 years to undergo inspections for signs of degradation at intervals of 10 years or less to win permission for continued operation. As long as they keep passing these periodical inspections, they can run beyond the 60-year limit.
The NRA is expected to work out, possibly by the end of the year, an outline of a draft revision of the Nuclear Reactor Regulation Law for the extended operations of nuclear plants.
The 40-year cap was a rule established under a bipartisan agreement reached through Diet debate that focused on the bitter lessons from the triple meltdown at the Fukushima No. 1 nuclear power plant in 2011. This rule, along with the suspension of new construction and expansion of nuclear power plants, played an important role in reducing the nation’s dependence on atomic energy, a policy goal adopted by the government. The rule must not be changed without national debate after only 10 years.
The NRA argues that whether to extend the legal life of reactors is a policy decision concerning the use of nuclear power that is outside its mandate. That means the NRA’s mandate is to ensure proper regulations of nuclear power generation according to the government’s policy.
At a glance, this position appears to be based on the principle of the separation of nuclear safety regulation from the government’s policy to promote nuclear power generation. But it is, in effect, regulation in line with promotion.
Nuclear power plants inevitably wear down over time. There are many plant parts that were not designed to be replaced. As the initial design philosophy for reactors has become outdated, the risk of unexpected problems and malfunctions increases. The 40-year rule was partly aimed at avoiding such unclear and unpredictable risks.
Extended life spans will inevitably increase the burden of inspections and raise the cost of electricity generated by aging reactors due to costs incurred by taking the necessary measures to pass inspections. This also raises questions about whether extended operations of reactors will make economic sense.
The NRA claims the regulations for reactors that have run for 30 years or longer would become “far more rigorous than now” under the proposed change. Some NRA experts have said the new system should make it harder for older reactors to pass inspections. Others have pointed out the importance of responding to the risks posed by natural disasters like earthquakes, tsunami and volcanic eruptions.
But the specifics of the new regulations and operational rules remain unclear. The ongoing policy debate on the issue, clearly driven by arguments for promoting nuclear power, raises doubts about whether the government could develop a new regulatory system that can win the support of the residents and administrations of host communities and the public as a whole.
To prevent another nuclear tragedy, it is vital for the NRA to remain solidly committed to maintaining its independence. Serious doubt about its independence would deliver a huge blow to its credibility with society.
If its independence is undermined, the NRA might be unable to resist future political pressure for relaxing the safety regulations or safety inspections of aged and risky reactors.
The NRA must realize that the situation poses a critical test of its commitment to its core mission as the nuclear safety watchdog.
Nuclear waste: from Bure in the Meuse, France to Japan, opponents of the burial unite
In Bure, in the Meuse, the Cigéo project for the burial of long-lived nuclear waste has been recognized as being of public utility. Opponents are calling on the Japanese to mobilize against a similar project on the island of Hokkaido.
Opponents of the Bure nuclear waste burial project have lent their support to the inhabitants of Suttsu, Japan, where a similar project is under study.
Ouest-France Alan LE BLOA. Published on 03/11/2022
On the borders of the Meuse and Haute-Marne regions, the Cigéo project for a nuclear waste burial center in Bure has been declared to be in the public interest. The decree, published on Friday, July 8, authorizes the National Agency for Radioactive Waste Management (Andra) to acquire the land needed for the surface installations, as well as the land located above the galleries. This means about 3,500 hectares, which can be expropriated if necessary.
85,000 m3 of radioactive waste
The aim of the project is to bury 85,000 cubic meters of long-lived high-level and intermediate-level radioactive waste from France’s nuclear power plants 500 meters underground by at least 2080. This decisive step, since the launch of research on site twenty years ago, has rekindled tensions. Some thirty associations and residents have filed an appeal with the Council of State to challenge the decision. A message relayed to Japan
On September 16, EELV and LFI parliamentarians gave their political support to the opponents’ action… which is becoming international. In a message relayed to Japan, they have, in fact, sent their support to the inhabitants of the village of Suttsu, opposed to the project of burying radioactive waste in the subsoil of the island of Hokkaido, in the north of the archipelago. The burial projects “are devastating for our territories and represent economic brakes for their future. No one wants to live next to a radioactive repository. The promises of development are lies intended to make the projects acceptable”, they write, condemning “the lack of transparency of the authorities”.
In the meantime, in Bure, an observatory for the health of local residents is being set up. Its objective? To monitor the physical and psychological health of residents within a 25 km (6,000 people in 180 municipalities) and 50 km (340,000 people in 679 municipalities) perimeter. Some 900 people, selected at random, are to be interviewed to assess their health.
Nuclear waste: in Japan, a sensitive project in an earthquake-prone region
On the island of Hokkaido, a contested project plans to bury 19,000 tons of radioactive waste 300 m underground. In a region subject to the risk of earthquakes.
Yugo Ono, geologist and professor emeritus at the University of Hokkaido, considers that it is risky to bury radioactive waste in an area subject to seismic movements.
Ouest-France Johann FLEURI. Published on 03/11/2022 at 06h30
On the island of Hokkaido, Numo is carrying out stage 1 of the investigation, which began in 2020. The radioactive waste management company is studying the location, soils, seismic history of the area and calculating budgets. Residents and the city council will be asked to vote on whether to proceed with the project and move to Phase 2. The vote, scheduled for November, has been postponed.
Stored for over a thousand years
The 19,000 tons of nuclear waste that could eventually be buried on site, between 300 m and 3 km below the surface of the ground, are extracts of liquid waste, which after several treatments, remain highly radioactive and must be stored for more than a thousand years, to no longer present a danger to humans. The burial project, the first of its kind in the archipelago, consists of placing them in stainless steel tubes, so that they can be stored as vitrified waste. Numo plans to store 40,000 of these containers underground.
Soil and water table
An underground project that seems risky in a country subject to earthquakes. At Numo, we believe that “the degree of danger is under control”. In the event of a major earthquake, “the containers will follow the movement of the earth”. But Yugo Ono, a geologist and professor emeritus at Hokkaido University, does not share this opinion. “Buried, the waste could pollute the soil and groundwater in the event of a strong earthquake,” he says.
Risks
“The geology of the region, composed of volcanic rocks, is unsuitable for such a project, says the scientist. The soil is very affected by seismic activity. In the case of a major earthquake in Suttsu, “the radioactivity will spread into the water table,” he says. The waste would be stored at a depth of 300 meters, while “seismic activity can be felt up to 10 kilometers down.” Under pressure, the expert is certain: “The tanks will break.”
Another method
Rather than burial, “the only method of storing radioactive waste for Japan today is in steel containers, covered with 2 meters of concrete, within the walls of nuclear power plants. According to Yugo Uno, “this is the safest method, which we master best and it is not so expensive”. But this system requires that the containers be changed every fifty years at the most because the steel will be attacked by radioactivity. “Every twenty years would be better for maximum safety.”
REPORT. In Suttsu, Japan, the inhabitants do not want nuclear waste
At a time when Japan is announcing the restart of seventeen nuclear reactors by 2023, the question of radioactive waste management arises. In Suttsu, a landfill project is under study, to the great despair of the inhabitants.
Miki Nobuka, 50 years old, says she learned that the project of nuclear waste burial was validated while she was buying her bread.
Ouest-France Johann FLEURI. Published on 03/11/2022
“We don’t want our village to become a garbage dump,” say Kazuyuki Tsuchiya and his wife Kyoko. This couple of septuagenarians runs an inn in Suttsu, located on the island of Hokkaido, in northern Japan. This village of 2,800 souls, 78% of which is made up of forests, is picturesque and is located between mountains and the sea.
It is here that a nuclear waste storage project has been taking shape since 2020. Suttsu and the neighboring village of Kamoenai (800 inhabitants) were the only ones to apply to the Radioactive Waste Management Corporation (Numo), created by the Ministry of Economy, Trade and Industry and the electricity companies, and were selected to receive, within 20 years, the 19,000 tons of radioactive waste piling up in the country’s power plants, particularly in Fukushima Dai-chi and Rokassho in Aomori, where storage capacity is saturated.
In Japan, between the villages of Suttsu and Kamoenai, which have applied for the radioactive waste burial project, is the Tomari nuclear power plant. In Japan, between the villages of Suttsu and Kamoenai, which have applied for the radioactive waste disposal project, is the Tomari nuclear power plant.
Although Suttsu officially submitted its application, the inhabitants feel that they were not consulted and accuse the municipal council of having made the decision alone. Miki Nobuka, 50 years old, says she learned that the project was approved while she was buying her bread. This mother has been campaigning ever since to “stop it for our children”.
More than 50% of the inhabitants against
According to Kazuyuki Tsuchiya’s calculations, “more than 50% of the inhabitants of Suttsu are against”. Not having had access to the details of the project, “the council makes heavy decisions in plenary sessions”. The residents feel betrayed and angry. “The mayor wants to take advantage of the subsidies to develop the city, but we don’t want it,” he says.
According to Kazuyuki Tsuchiya’s calculations, “more than 50 percent of the residents of Suttsu are against” the radioactive waste disposal project.
In the first phase of the project, which consists mainly of soil investigation, 15 million euros are paid to each of the two municipalities. Fifty-three million in the second phase, which is to be voted on by referendum. The city council can say stop at any time,” says a Numo spokesperson. A vote will validate the continuation of each phase.”
Lack of transparency
But “we want to have access to all the documents: it’s unacceptable,” says Kazuyuki Tsuchiya, who won his case in the Hakodate administrative court last March for lack of transparency on the part of local authorities. The court ruled that the city of Suttsu should publicly share all the minutes of the city council meeting during which the vote for the final storage project was held. The vote for the second phase, originally scheduled for November, has therefore been postponed to a later date.
When contacted, the mayor of Suttsu refused to answer our questions. The Kishida government has announced the restart of 17 of its reactors by 2023 and the probable construction of new ones in the future. The Prime Minister also declared that before each restart, the local population, who live near the said plants, would be consulted. A promise that makes the inhabitants of Suttsu smile bitterly.
Japanese government seeks to allow nuclear reactors to operate for 80 years
Japanese authorities on Wednesday proposed that the safety of nuclear
plants aged 30 years or older be checked at least once a decade to obtain
approval for continued operation.
The proposal from the Nuclear Regulation
Authority came as the government seeks to scrap a rule that limits the
operating life of reactors to a maximum of 60 years. The regulator said the
proposed mandatory safety checks should also be applied to nuclear reactors
in use for more than 60 years.
It means that if the safety is confirmed,
Japan may be able to authorize nuclear plants to run for 80 years, as in
the United States. “The (proposed) regulations will be much stricter than
the current system,” Shinsuke Yamanaka, chairman of the nuclear watchdog,
said at a press conference. “It is our responsibility to regulate
properly.”

North Korea fired intercontinental ballistic missile – Seoul
https://www.rt.com/news/565844-north-korea-icbm-launch/ 4 Nov 22, The launch failed during the second-stage separation, a South Korean military official told Yonhap
North Korea has launched an intercontinental ballistic missile (ICBM) as part of a large-scale show of force against the ongoing war games between the US and South Korea, according to Seoul’s armed forces.
The South Korean Joint Chiefs of Staff said the military detected “what is presumed to be a long-range ballistic missile launch from the Sunan area in Pyongyang” early on Thursday morning, noting that two additional short-range missiles followed about one hour later.
After analyzing details of the launch, the military added that the weapon traveled a distance of around 760km (472 miles) and reached a top speed of Mach 15. However, a defense source later told Yonhap that “the missile seems to have failed in normal flight” after its second-stage separation.
In a statement later on Thursday, the Joint Chiefs said “Our military has beefed up surveillance and vigilance” and would maintain a “readiness posture in close cooperation with the US.”
Thursday’s launch marks the first time Pyongyang has fired an ICBM since May, though it comes amid a record number of missile tests overall this year. The DPRK has also unleashed hundreds of rockets, missiles, and artillery shells into the sea in recent days as a demonstration to Washington and Seoul, which are in the middle of some of their largest air drills ever.
With tensions soaring on the peninsula, the North has repeatedly condemned the exercises as a rehearsal for a full-scale invasion, even suggesting earlier this week that Washington could be preparing a nuclear attack. The US and South Korea, meanwhile, have denounced each missile launch by Pyongyang as a dangerous provocation and have vowed to continue strengthening military ties.
Studies on nuclear radiation’s impact on people necessary: BRIN
https://en.antaranews.com/news/258613/studies-on-nuclear-radiations-impact-on-people-necessary-brin 4 Nov 22, Jakarta (ANTARA) – Environmental and health studies on the impact of radiation exposure on people living in areas of high natural radiation, such as Mamuju, West Sulawesi, are necessary, the National Research and Innovation Agency (BRIN) has said.
A researcher from BRIN’s Research Center for Metrology Safety Technology and Nuclear Quality, Eka Djatnika Nugraha, said that in some places in Indonesia, such as Mamuju, people have been exposed to natural radiation that is several times higher than the global average at around 2.4 millisieverts per year.
“This situation may pose a health risk to the public due to chronic external and internal exposure,” Nugraha said in a statement received on Friday.
Mamuju is an area of high natural background radiation due to the high concentration of uranium and thorium in the rocks and soil, he observed.
Thus, studies on the health of people living in such areas could serve as a potential source of information about the effects of chronic low-dose exposure, he added.
In order to obtain scientific evidence on the effects of chronic low-dose radiation exposure on health, it is necessary to conduct a comprehensive environmental assessment of the exposure situation in areas of high natural radiation, he elaborated.
Meanwhile, head of BRIN’s Nuclear Energy Research Organization, Rohadi Awaludin, said that it is important to know and understand the safety and protection measures against nuclear radiation technology, especially for everyone involved or in contact with it.
“Nuclear radiation technology, including ionization, has been used and applied to various aspects, including industry and health, food, and others. This technology is the answer to the problems we have, but there are also risks that (one) must be (aware of) from this technology,” he added.
Poland, South Korea sign outline accords on nuclear power project
Aljazeera 31 Oct 22
South Korea and Poland to assess the viability of building four 1,400-megawatt nuclear reactors in Patnow.
Seoul and Warsaw have signed outline agreements to develop nuclear power in Poland, according to ministries from both countries, as Poland strives to phase out coal and lower its carbon emissions and South Korea seeks to revive its nuclear industry.
Poland’s ZE PAK and PGE and Korea Hydro & Nuclear Power (KHNP) will assess the viability of building four 1,400-megawatt nuclear reactors in Patnow, central Poland, using South Korean technology, the South Korean Ministry of Trade, Industry and Energy said on Monday in a joint statement with the Polish Ministry of State Assets.
The companies, with government backing, intend to prepare a preliminary development plan for the plant by the end of this year, they said in a statement.
Since the election this year of President Yoon Suk-yeol, who pledged to revive the country’s nuclear power industry, South Korea has stepped up efforts to win nuclear power plant export orders……………………
Monday’s agreements follow an announcement on Friday when Warsaw said US firm Westinghouse Electric Co will build the country’s first nuclear power plant in northern Poland. https://www.aljazeera.com/news/2022/10/31/poland-south-korea-sign-outline-accords-on-nuclear-power-project
Minister Vows Response to Fukushima Reputational Damage
https://www.nippon.com/en/news/yjj2022103000407/ Soma, Fukushima Pref., Oct. 30 (Jiji Press)–Japanese industry minister Yasutoshi Nishimura said Sunday the government will face and surely respond to local people’s concerns about reputational damage related to the planned release of treated radioactive water into the ocean from the disaster-crippled Fukushima No. 1 nuclear power plant.
The minister made the remark when he visited a fishing port in Soma, Fukushima Prefecture, northeastern Japan, and exchanged opinions with local fishery workers, who voiced such concerns.
Aiming to start the release of the treated water containing radioactive tritium around spring next year, the Japanese government and Tokyo Electric Power Company Holdings Inc. <9501>, the operator of the Fukushima No. 1 plant, have been giving explanations about the move to local people and proceeding with the construction of related facilities.
At the day’s meeting with Nishimura, the fishery workers called for measures that would allow Fukushima fishery products to be sold at fair prices. They also asked the central and Fukushima governments to work in closer cooperation so that local opinions can be taken in swiftly.
After the meeting, Nishimura told reporters, “We’ll launch the work to establish a new framework for communicating the attractiveness of Fukushima’s fishery products and boosting their consumption through cooperation with businesses and local governments across Japan.” He added that the government will give details of the plan possibly by the end of the year.
India headed towards 100% renewables power by 2050
A new optimistic Nature paper from the LUT University in Finland looks to a
key role being played by renewables for rapid transitioning of the power
sector across states in India. Progress has been uneven at times, but LUT
says that a renewables-based power system by 2050 could be ‘lower in cost
than the current coal dominated system’ and have ‘zero greenhouse gas
emissions’ while providing ‘reliable electricity to around 1.7 billion
people’.

Bring voices from the coast into the Fukushima treated water debate
PNAS Leslie Mabon and Midori Kawabe 28 Oct 22, More than a decade has passed since the accident at the Fukushima Dai’ichi nuclear power plant in Japan—but the most contentious aspect of bringing the site under control is only just beginning. The Japanese Government has approved plant operator TEPCO’s plan to release treated water into the Pacific Ocean. That water is currently being stored onsite and retains some radioactive substances after treatment. The decision to release this water has provoked political contention and societal concern. South Korea, China, and Taiwan, as well as international environmental nongovernmental organizations, have expressed strong concern; and fisheries cooperatives in Japan remain opposed to the releases for fear of possible reputational impacts on Fukushima seafood.
TEPCO are confirming specific details of the release process, and an International Atomic Energy Agency (IAEA) task force has made multiple visits to the Fukushima Dai’ichi site at the behest of the Japanese Government and TEPCO. The releases are scheduled to start in 2023 and run for many years………………………………………
Even if TEPCO and the government minimize environmental impacts through careful management of the process, as some international experts believe possible (3), the indirect socioeconomic impacts of the treated water releases on Fukushima’s coastal fishing communities are likely to be experienced over the long term. Proposals made by the community of researchers and institutions working at the science–policy interface for Fukushima treated water must be informed by a deep understanding of the local community context—and they must be responsive to the concerns of local stakeholders. We believe local community concerns can be more fully incorporated into decision making for treated water at Fukushima Dai’ichi………………….
Local Influence
Within Japan, the government expert committees advising the management of treated water are dominated largely—albeit not exclusively—by engineering and physical science expertise (4). Despite fisheries cooperatives’ long-standing and vocal opposition to the releases, plant operator TEPCO explained in August 2021 that they had not at that point had direct consultations with fisheries representatives regarding the discharges (5). Formal dialogue between the operator and the fisheries sector in Fukushima on the topic of releases did not start until TEPCO and the Japanese Government had determined most of the technical details. This left little room for the plans to be adjusted in response to any concerns from Fukushima’s fishers or coastal residents…………………………
Both within Japan and internationally, Fukushima’s fishers and coastal residents, although not completely absent, have received limited consideration as stakeholders. Fishers and residents tend to be caricatured as being concerned over rumors and reputational damage to Fukushima seafood owing to the treated water releases (9, 10)—or as harboring “irrational” safety fears over the relatively small amounts of radioactivity from pollutants such as tritium that are contained in the tanks currently storing treated water onsite (e.g., 3)………….
Missing Local Context
The Japanese Government is unlikely to reverse their decision to release treated water. Even so, it’s important to recognize that fishing is both an economic activity and the subject of deep emotional investment on the Fukushima coast. ……………………………….more https://www.pnas.org/doi/10.1073/pnas.2205431119
US, Japan, S Korea vow response if N Korea tests nuclear bomb
US says full military capabilities will be used, including nuclear, to protect its allies South Korea and Japan.
An “unparalleled” scale of response would be warranted if North Korea conducts a seventh test of a nuclear weapon, the United States, Japan and South Korea have warned.
The warning was issued on Wednesday amid concerns by the US and its regional allies that North Korea could be poised to resume nuclear bomb testing for the first time since 2017.
“We agreed that an unparalleled scale of response would be necessary if North Korea pushes ahead with a seventh nuclear test,” South Korean first vice foreign minister Cho Hyun-dong told a news conference in Tokyo.
Cho made his comments alongside Japan’s vice foreign minister Takeo Mori and US Deputy Secretary of State Wendy Sherman.
North Korea has been carrying out weapons tests at an unprecedented pace this year, firing more than two dozen short and medium-range ballistic missiles in recent weeks, including a missile that over-flew Japan.
We urge (North Korea) to refrain from further provocations,” Sherman said, calling the North’s actions “reckless” and deeply destabilising for the region.
Sherman also said that the US will use its full military capabilities, “including nuclear, conventional and missile defence”, to protect its allies Japan and South Korea.
North Korea needs to understand that the US commitment to the security of South Korea and Japan is “iron clad”, she said.
“And we will use the full range of US defence capabilities to defend our allies, including nuclear, conventional and missile defence capabilities,” she said.
US State Department spokesman Ned Price said in a statement that Sherman also reiterated that the US was continuing to “seek serious and sustained dialogue with the DPRK” (Democratic People’s Republic of Korea) – the official name for North Korea.
Cho, during his talks with Sherman, raised concern that a new North Korean nuclear weapons policy adopted in September increases the possibility of its arbitrary use of nuclear weapons.
“This is creating serious tension on the Korean peninsula,” Cho said.
In September, the USS Ronald Reagan and accompanying ships conducted joint military exercises with South Korean forces in response to a North Korean ballistic missile test in what was their first joint military training involving a US aircraft carrier since 2017.
Angered by South Korea’s military activities, Pyongyang last week fired hundreds of artillery shells off its coasts in what it called a grave warning to its neighbour to the south.
Sherman met earlier on Tuesday with Japan’s Mori and reaffirmed the further strengthening of the Japan-US alliance and other shared goals, including the complete denuclearisation of North Korea and their joint response to China’s increasingly assertive actions in the region.
Japanese defence minister Yasukazu Hamada recently said that North Korea is believed to have achieved a miniaturisation of nuclear warheads while significantly advancing its missile capabilities by diversifying its launch technologies, making interceptions more difficult.
Japan has joined South Korea in also warning of a possible nuclear test by North Korea in the near future.
Takahama Unit 4 postpones resumption of operation due to rising equipment temperatures
October 21, 2022
On October 21, KEPCO announced that it had postponed the restart of the Takahama Unit 4 reactor, which is currently shut down for routine inspections, due to a temperature rise in one of the devices inside the reactor containment vessel that is activated when there is a problem with the primary cooling system. The reactor startup scheduled for the 21st will be postponed due to a temperature rise in one of the devices that operates in the reactor containment vessel in the event of a primary cooling system problem.
After the reactor start-up on the 21st, the plant was scheduled to resume power delivery on the 24th and commercial operation on November 18. KEPCO was planning to resume commercial operation on November 18. KEPCO is investigating the impact on the process and the cause of the temperature rise.
According to KEPCO, the temperature rose because of one of the safety devices used to reduce the pressure that rose due to a problem in the primary cooling system. The temperature was 4.2 degrees Celsius at around 3:30 p.m. on March 21, but it rose to 77 degrees Celsius at around 4:35 p.m., triggering an alarm.
