Kansai to start loading fuel at Ohi 3 ahead of restart

The loading of fuel assemblies into the core of unit 3 at the Ohi nuclear power plant in Japan’s Fukui Prefecture will begin tomorrow, Kansai Electric Power Company announced. The utility plans to return both units 3 and 4 at the plant to commercial operation by mid-2018.

Following the shutdown of all of Japan’s reactors after the March 2011 accident at the Fukushima Daiichi plant, Ohi 3 and 4 were given permission to resume operation in August 2012. However, the two 1180 MWe pressurised water reactors (PWRs) were taken offline again for Nuclear Regulation Authority (NRA) inspections in September 2013.
 
Under Japan’s reactor restart process, plant operators are required to apply to the NRA for: permission to make changes to the reactor installation; approval of its construction plan to strengthen the plant; and, final safety inspections to ensure the unit meets new safety requirements. Operators are required to add certain safety-enhancing equipment within five years of receiving the NRA’s approval of a reactor engineering work programme.
 
Kansai submitted its construction plan application for Ohi 3 and 4 in July 2013. The NRA approved the plan for strengthening the units in August last year.
 
Following pre-operation inspections of the units to confirm that the safety countermeasure equipment complies with the approved construction plan at the plant, Kansai is now set to start loading fuel into unit 3 ahead of its restart. In November, the utility said it expected to restart the reactor around mid-March, with commercial operation scheduled from early-April.
 
The governor of Japan’s Fukui Prefecture approved the restart of Ohi units 3 and 4 in November. Unit 4 is also expected to be restarted in the coming months. Kansai earlier said it expects to refuel the reactor in mid-April, restart it around mid-May, with commercial operation expected to resume in early June.
 
In December, Kansai announced that it will not seek permission to restart Ohi units 1 and 2, which have been offline since July 2011 and December 2011, respectively. The company will now apply to decommission the two 1175 MWe PWRs, which are approaching 40 years old.
 
Of Japan’s 42 operable reactors, five have so far cleared inspections confirming they meet the new regulatory safety standards and have resumed operation. These are: Kyushu’s Sendai units 1 and 2; Shikoku’s Ikata unit 3; and Kansai’s Takahama units 3 and 4. Another 19 reactors have applied to restart.

Abe, ex-Prime Minister Kan go head to head in nuclear debate

jkllmmùù.jpg
Prime Minister Shinzo Abe, right, and former Prime Minister Naoto Kan at a Lower House Budget Committee session on Feb. 6
Prime Minister Shinzo Abe and predecessor Naoto Kan had a rare face-to-face showdown at a Lower House Budget Committee session over their nuclear energy policies on Feb. 6.
Abe admitted that his Liberal Democratic Party shares partial responsibility for failing to prevent the Fukushima nuclear emergency, but slammed those who advocate abandoning nuclear power generation as irresponsible.
The triple meltdown at the Fukushima No. 1 nuclear power plant, triggered by the 2011 earthquake and tsunami disaster, occurred when the now-disbanded Democratic Party of Japan was in power and Kan was prime minister. He is now a member of the Constitutional Democratic Party of Japan.
Most of the nation’s nuclear plants were built on the back of the LDP’s energy policy during the party’s long stints in power.
“The LDP did not give sufficient consideration to (safety issues of) nuclear facilities while it was in power (before the DPJ’s tenure), did it?” Kan accused Abe. “The LDP should admit its part in failing to prevent the Fukushima accident.”
Abe responded: “That is absolutely correct. The government and the nuclear plant operator were blinded by the safety myth (that nothing catastrophic could happen to a Japanese nuclear power plant), and that caused such tragedy.”
Abe also blasted the no-nuclear plant policy promoted by former LDP Prime Minister Junichiro Koizumi and like-minded lawmakers from opposition parties, saying he “cannot recognize it as a responsible energy policy.”
In an argument over the true cost of nuclear power generation, neither Abe nor Kan would budge from their viewpoints.
Abe indicated he will continue to support restarting nuclear plants around Japan, saying “power bills paid by typical households rose by about 10 percent (on average) while many nuclear plants remained offline.”
Kan condemned Abe’s position as “calculating only what is convenient for yourself,” pointing out that the cost for dealing with the accident’s aftermath and radiation contamination has already more than doubled from what was initially expected.

Desperate to save its failing nuclear business, Toshiba looks to Ukraine

Toshiba seeks deal in Ukraine to revive nuclear power business, Asahi Shimbun, By TOSHIO KAWADA/ Staff Writer, February 8, 2018  Toshiba Corp. is planning another foray into an overseas nuclear-power industry, forced in part by the disastrous consequences of its previous failure abroad, sources said.

The Tokyo-based company has started negotiations with Energoatom, a Ukrainian state-run power company, to supply turbine generators for use in its nuclear power plants. The two companies concluded a memorandum in October 2017.

Toshiba in March 2017 said it was withdrawing from the business of designing and constructing entire nuclear power plants overseas following the collapse of its U.S. nuclear arm, Westinghouse Electric Co.

However, Toshiba judged that it would not suffer such a huge deficit again if it only supplies equipment to nuclear power plants abroad, the sources said.

“There will be little concern that we will suffer a huge loss (from an overseas deal),” a source related to Toshiba said.

Energoatom operates 15 nuclear reactors and is building two others in Ukraine. It plans to replace the generators of old reactors to increase output.

Toshiba wants to win a deal with Energoatom to export the replacement generators and provide maintenance services after they go into operation.

If Toshiba succeeds in the equipment supply business in Ukraine, it will consider looking at other markets abroad, the sources said.

Toshiba is desperate for a steady source of income…….

Toshiba plans to earn steady profits from its nuclear business, believing competition with other companies will not be so fierce, the sources said.

But if this endeavor fails to pan out, Toshiba’s management situation could worsen. http://www.asahi.com/ajw/articles/AJ201802080050.html

Taiwan’s problem in searching for geological location for nuclear waste dump

GDF Watch 5th Feb 2018, Taiwan has published a report today on their geological disposal plans. The
country has decided to prioritise looking for granite-based locations for
the disposal of high-level radioactive waste, but acknowledged that such
locations were limited to only a small part of Taiwan.

The proposal is the conclusion of an 11-year study to evaluate suitable host rock suitable for
storing spent fuel. Energy company Taipower, which is responsible for
managing radioactive waste, said it will give priority to assessing the
building of a national geological repository in granite because Sweden and
Finland have also chosen granite-based sites for their waste repositories.
But it has not ruled out other host rock choices.

American companies’plans to market nuclear technology to India have come to nothing

The Hindu 3rd Feb 2018, Watching the Republic Day parade, where 10 ASEAN leaders were chief guests,
it was easy to miss the fact that the dates of their visit also marked the
anniversary of another big visit three years ago: the visit by then U.S.
President Barack Obama, when he announced a “breakthrough” in the
India-U.S. civil nuclear deal, to finally pave the way for a commercial
contract.

“The deal is done,” Sujatha Singh, who was Foreign Secretary
at the time, said as the government issued papers and held briefings
describing the nature of the agreement between India and the U.S. on
supplier liability and tracking requirements, which would enable American
companies to build nuclear power reactors in India.

Today, nearly a decade since the memoranda of understanding were inked, and three years after the
last wrinkles were ironed out, there is no sign yet of any concrete
contract between an American company and the Indian authorities to build a
reactor.

In 2009, both GE-Hitachi and Toshiba-Westinghouse had begun talks
on techno-commercial agreements for six reactors each in India. These
commercial contracts were to be the start of the ‘payoff’ for the U.S.
that had considerably shifted its stand on non-proliferation to give India
the waivers needed, and they were to herald India’s arrival on the global
nuclear power stage in return.

Instead, GE-Hitachi’s plans were shelved after it rejected the Obama-Modi agreement in January 2015, saying GE would
not accept the compromise formula on supplier liability. (While others have
indicated they would accept the liability offer, none of them has put that
on paper.) Toshiba-Westinghouse then carried the baton to actualise the
India-U.S. civil nuclear deal, but ran into a different storm as both
Toshiba and Westinghouse had major financial troubles last year. After a
near-bankruptcy, Toshiba jettisoned Westinghouse for just $4.6 billion to a
Canadian consortium, a deal that is now expected to be cleared by the end
of 2018.

The mammoth task of cleaning up Fukushima’s radioactive nuclear reactor wrecks has only just begun

Power Engineering 31st Jan 2018, Worst-Hit Reactor at Fukushima May be Easiest to Clean Up. High atop Fukushima’s most damaged nuclear reactor, the final pieces of a jelly-roll shaped cover are being put in place to seal in highly radioactive dust.

Blown apart by a hydrogen explosion in 2011 after an earthquake and tsunamihit Japan’s Fukushima Dai-ichi plant, reactor Unit 3 is undergoing painstaking construction ahead of a milestone that is the first step toward dismantling the plant. The operating floor — from where new fuel rods
used to be lowered into the core — has been rebuilt and if all goes as planned, huge cranes will begin removing 566 sets of still-radioactive fuel
rods from a storage pool just below it later this year.

It has taken seven years just to get this far, but now the real work of cleaning up the Tokyo Electric Power Co. plant can begin. “If you compare it with mountain climbing, we’ve only been preparing to climb. Now, we finally get to actually start climbing,” said Daisuke Hirose, an official at the plant’s decommissioning and decontamination unit.

Cleaning up the plant’s three reactors that had at least partial meltdowns after the earthquake and tsunami is a monumental task expected to take three to four decades. Taking out the stored fuel rods is only a preliminary step and just removing the ones in Unit 3 is expected to take a year. Still ahead is the uncharted challenge of removing an estimated 800 tons of melted fuel and debris inside the cracked containment chambers — six times that of the 1979 Three Mile Island accident.  http://www.power-eng.com/articles/2018/01/worst-hit-reactor-at-fukushima-may-be-easiest-to-clean-up.html

Artificial intelligence to enhance the thinking skills of nuclear submarine commanding officers,

China’s plan to use artificial intelligence to boost the thinking skills of nuclear submarine commanders
Equipping nuclear submarines with AI would give China an upper hand in undersea battles while pushing applications of the technology to a new level, 
SCMP, Stephen Chen,  05 February, 2018,  China is working to update the rugged old computer systems on nuclear submarines with artificial intelligence to enhance the potential thinking skills of commanding officers, a senior scientist involved with the programme told the South China Morning Post.

A submarine with AI-augmented brainpower not only would give China’s large navy an upper hand in battle under the world’s oceans but would push applications of AI technology to a new level, according to the researcher, who spoke on condition of anonymity because of the project’s sensitivity.

“Though a submarine has enormous power of destruction, its brain is actually quite small,” the researcher said.

While a nuclear submarine depends on the skill, experience and efficiency of its crew to operate effectively, the demands of modern warfare could introduce variables that would cause even the smoothest-run operation to come unglued.

For instance, if the 100 to 300 people in the sub’s crew were forced to remain together in their canister in deep, dark water for months, the rising stress level could affect the commanding officers’ decision-making powers, even leading to bad judgment.

An AI decision-support system with “its own thoughts” would reduce the commanding officers’ workload and mental burden, according to the researcher……….

Up till now, the “thinking” function on a nuclear sub, including interpreting and answering signals picked up by sonar, a system for detecting objects under water by emitting sound pulses, has been handled almost exclusively by human naval personnel, not by machines.

Now, through AI technology, a convolutional neural network undergirds so-called machine learning. This structure underpins a decision support system that can acquire knowledge, improve skills and develop new strategy without human intervention.

By mimicking the workings of the human brain, the system can process a large amount of data. On a nuclear submarine, data could come from the Chinese navy’s rapidly increasing observation networks, the submarine’s own sensors or daily interactions with the crew…….. http://www.scmp.com/news/china/society/article/2131127/chinas-plan-use-artificial-intelligence-boost-thinking-skills

China wants USA to drop its “Cold War mentality

China accuses US of ‘Cold War mentality’ over nuclear policy BBC News 4 Feb 18 China has urged the US to drop its “Cold War mentality” after Washington said it planned to diversify its nuclear armoury with smaller bombs.”The country that owns the world’s largest nuclear arsenal, should take the initiative to follow the trend instead of going against it,” China’s defence ministry said on Sunday.

The US military believes its nuclear weapons are seen as too big to be used and wants to develop low-yield bombs.

Russia has already condemned the plan.

Iran’s foreign minister claimed it brought the world “closer to annihilation”……….

China said on Sunday it “firmly” opposed the Pentagon’s review of US nuclear policy.

The defence ministry in Beijing said Washington had played up the threat of China’s nuclear threat, adding that its own policy was defensive in nature.

“We hope that the United States will abandon its Cold War mentality, earnestly assume its special disarmament responsibilities, correctly understand China’s strategic intentions and objectively view China’s national defence and military build-up,” its statement said. …..http://www.bbc.com/news/world-asia-42935758

Pre-emptive strike on North Korea  – “tempting” “a rational argument” -says Kissinger

A nuclear first strike of North Korea is ‘tempting’, says legendary U.S. diplomat Henry Kissinger as Kim Jong-un warns Trump is pushing towards war, Daily Mail, 2 Feb 18   

  • Kissinger, 94, warned that North Korean  denuclearization was vital 
  • He said that relations with Kim Jong-un’s country have reached a key juncture 
  • The U.S. must now choose between pre-emptive military action or increasingly tighter sanctions, he said
  • His warning came before North Korea warned that the U.S. is pushing the whole world towards a ‘nuclear war’ 

    By Alastair Tancred For Mailonline and Afp  3 February 2018 

Former Secretary of State Henry Kissinger has said that the temptation to launch a pre-emptive strike on North Korea ‘is strong and the argument rational’.

He told a meeting of the Senate Armed Services Committee last week that North Korea poses the most immediate threat to global security, arguing that denuclearization of the regime must be a ‘fundamental’ American foreign policy goal.

The veteran diplomat was speaking before North Korea warned that the U.S. is pushing the whole world towards a ‘nuclear war’ in its latest letter submitted to the UN.

Former U.S. secretary of state Henry Kissinger), former secretary of state George Shultz, and former deputy secretary of state Richard Armitage, were testifng before the Senate Armed Services Committee on global security challenges

It said that joint military exercises between the U.S. and South Korea – coupled with American rhetoric in the Korean peninsula region – were bound to derail improving relationships between the two Koreas.

 The Trump administration’s aims are ‘to provoke a nuclear war, which will undermine the improvement of inter-Korean relations and the easing of tensions,’ North Korean Foreign Minister Ri Yong Ho said in the letter to U.N. Secretary-General Antonio Guterres.

Mr Kissinger said that relations between the U.S, and north Korea had reached ‘a fork in the road’ in which the Trump administration may consider pre-emptive military action or increasingly tighter sanctions against Kim Jong-un’s regime.

‘We will hit that fork in the road, and the temptation to deal with it with a pre-emptive attack is strong, and the argument is rational, but I have seen no public statement by any leading official,’ President Nixon’s secretary of State told members of the Committee.

Kissinger, who at 94 continues to advise on foreign policy matters, joined two other foreign policy heavyweights – former Secretary of State George Shultz, 97, and ex-Deputy Secretary of State Richard Armitage, 72 — in testifying to the Committee about global security challenges.

The elder statesmen presented a picture of mounting international threats, including nuclear proliferation, Chinese authoritarianism, and Russia’s interference in US elections and its interventions in Eastern Europe.

‘The most immediate challenge to international security is posed by the evolution of the North Korea nuclear program,’ Kissinger told the Senate Armed Services Committee, describing an ‘unprecedented’ scenario………… http://www.dailymail.co.uk/news/article-5344473/Kissinger-Nuclear-strike-North-Korea-tempting.html

History of rare earths processing disaster in Malaysia

A factory processing radioactive materials in Perak gave the people living nearby leukemia.

Bukit Merah’s rare earth metal processing site cleanup had been the largest radiation cleanup so far in the world’s rare earth industryDr. Yoshihiko Wada’s report revealed that Mitsubishi Chemical came up with ARE in Bukit Merah after being one of the main companies that caused severe asthma in Nagoya, Japan. Also, 100% of the rare earth products processed in Bukit Merah were exported back to Japan, so it’s not like we gained anything but money from the venture, which puts forth the question of whether it’s worth endangering the lives of local residents for rare earth metals.

Earlier this year, Lynas Corporation had been popping up in the news again. For those of who have no idea who or what Lynas is, a few years back there had been a hullabaloo when Lynas set up a rare-earth processing plant in Gebeng, Kuantan, called the Lynas Advanced Materials Plant (LAMP).

Top U.S. nuke envoy says Washington wants talks with N.K. for denuclearization 

http://english.yonhapnews.co.kr/northkorea/2018/02/02/0401000000AEN20180202008700315.html  SEOUL, Feb. 2 (Yonhap) — The top U.S. nuclear envoy said Friday that Washington wants to open dialogue with North Korea for its denuclearization.

After meeting with South Korean Vice Unification Minister Chun Hae-sung in Seoul, Joseph Yun also told reporters that he sees the resumed inter-Korean talks and easing tensions after the North’s decision to join the upcoming Winter Olympics as a “good opportunity” for denuclearization efforts.

“We want to open dialogue with North Korea, we want to have a credible dialogue, a dialogue that could lead steps towards denuclearization,” he said. “That is our goal and of course President Moon has also emphasized that goal too.”

China reorganising its nuclear companies in order to export nuclear technology

China goes nuclear with latest state-brokered power deal, Josephine Mason, David Stanway
BEIJING (Reuters) 2 Feb 18, –
 China National Nuclear Corp (CNNC), China’s No. 2 nuclear power producer, will take over the country’s top nuclear power plant builder to create a company worth almost $100 billion, the latest state-orchestrated marriage in the nation’s vast power sector. 

Approval for the tie-up between CNNC and China Nuclear Engineering & Construction (CNEC) was announced by the State-Owned Assets Supervision and Administration Commission (SASAC) on Wednesday in a one-line statement posted on its website…….

Beijing wants to overhaul its nuclear sector in order to create globally competitive firms and reduce overcapacity across its broader power market. The nuclear industry is struggling with project delays and a slowdown in approvals for new domestic projects.

By creating a unified home-brand series of reactors, and combining firms, China will be better positioned to bid for and finance overseas projects, experts say.

Both companies have built nuclear plants overseas, including in Pakistan, and developing Chinese nuclear technology abroad is a key goal of China’s Belt and Road initiative…… https://www.reuters.com/article/us-china-power-nuclear/china-goes-nuclear-with-latest-state-brokered-power-deal-idUSKBN1FK0S4

Britain’s new nuclear build – a profitable “golden era” for China’s State-owned nuclear companies

Xinhuanet 1st Feb 2018, China General Nuclear Power Corporation (CGN), a major Chinese nuclear
power operator, said Wednesday that nuclear projects in Britain were
proceeding well. He Yu, chairman of the board of CGN, said since the deals
were inked in 2016 with French energy company EDF and the British
government, CGN has invested 1.7 billion British pounds in order to advance
the projects. CGN signed agreements in 2016 for Hinkley Point C (HPC), a
nuclear project in Somerset, and a suite of agreements relating to the
Sizewell C (SZC) in eastern England and Bradwell B projects (BRB) in Essex.
“A total of 15 Chinese suppliers and contractors have passed a preliminary
qualification assessment for the HPC project,” He said. “HPC, which is
Britain’s first new nuclear power station in a generation, is the largest
construction in Europe.”
http://www.xinhuanet.com/english/2018-02/01/c_136940068.htm

Reuters 31st Jan 2018, Notable Chinese investments in Britain include the Hinkley C nuclear power
station which is being built by China General Nuclear Power Corp and the
British arm of France’s EDF (EDF.PA), while British firms, such as Rolls
Royce (RR.L), have won large deals from Chinese firms to supply items like
plane engines. Both May and senior Chinese officials have restated their
commitment to the “golden era” in ties but a row over May’s decision
to delay approval for the Chinese-funded Hinkley nuclear plant in late 2016
chilled relations. However, Britain was the first Western country to sign
up to the China-backed Asian Infrastructure Investment Bank and it sent
Finance Minister Philip Hammond to a Beijing summit last year about
President Xi Jinping’s flagship ‘Belt and Road Initiative’ – a
trillion-dollar infrastructure-led push to build a modern Silk Road.

Japan Should Clarify its Plutonium Usage Plans

GettyImages-480450645-compressor.jpg
Japan possesses almost 47 tons of separated plutonium. A clear plan for its potential usage and storage is essential.
This will be an important year for Japanese nuclear energy planning, as it will announce its domestic and foreign nuclear energy and plutonium policy. Japan, the only non-nuclear-weapon state (NNWS) with a civilian reprocessing capability, has faced some proliferation concerns. Despite this, Japan has consistently pledged their peaceful usage of their approximately 46.9 tons of separated plutonium, potentially enough to make over 5,000 nuclear weapons. Other East Asian countries have expressed worries about the storage of this much material.
Big events for Japanese nuclear energy planning
The “Strategic Energy Plan,” due to be released later this year, sets the fundamental direction of Japan’s energy policy. Japan’s Basic Energy Law mandates that the government release an energy plan every three years, and the current plan was the first to be released after the 2011 Fukushima accident.
The U.S.-Japan peaceful nuclear cooperation agreement, commonly referred to as the U.S.-Japan 123 Agreement, is the key pact that allows Japan to have two critical technologies: reprocessing and enrichment. The plutonium separated through reprocessing can be recycled into MOX fuel (plutonium-uranium mixed oxide) for light-water reactors. Since Japan lacks natural resources, recycled spent fuel could help to reduce dependence on foreign energy sources. The 123 Agreement stipulated that by July 2018 the United States and Japan must have a new agreement in place or allow the existing one to remain in force. Japan and the United States decided to automatically renew this agreement on January 17, 2018.
North Korean nuclear and missile tests have helped create dramatic changes in security environments in East Asia. In response to those changes, Japan should re-commit to reducing its plutonium stockpile.
Japanese commitment to reduce plutonium
Plutonium in spent fuel is not weapons-usable. Once this reactor-grade plutonium is separated from spent fuel through reprocessing, it is potentially nuclear weapons-usable. Japan owns approximately 9.8 tons of separated plutonium at home and 37.1 tons of separated plutonium at reprocessing plants in the United Kingdom and France.
Over the past six years, the Nuclear Security Summits made progress to strengthen nuclear security and reduce the threat of nuclear terrorism. The 2014 Hague produced a communiqué that encouraged states to keep their stockpile of separated plutonium as low as possible. Additionally, Japanese Prime Minister Abe stated that Japan would not possess separated plutonium for which it did not already identify a specific use during the 2014 Hague summit.
While Japan pledged to maintain their no-surplus plutonium policy, the disarray that continues to plague Japan’s nuclear industry—following the 2011 Fukushima nuclear accident, new regulations and delays in completing and opening the Rokkasho reprocessing plant, and decisions to close the MONJU fast breeder reactor—throws into question the credibility of Japan’s plutonium consumption plan. With approximately 46.9 tons of separated plutonium, Japan’s no-surplus plutonium policy looks hollow to date.
Important steps for Japan and the international community
On January 17, 2018, the U.S.-Japan peaceful nuclear cooperation agreement automatically renewed, which allows Japan to continue reprocessing spent nuclear fuel and uranium enrichment.
Japan’s stockpile of separated plutonium, consumption plan, and advanced nuclear technology have raised proliferation concerns in East Asia. Despite several legal restrictions on Japan’s ability to develop nuclear weapons—the Nuclear Non-Proliferation Treaty, Article 9 of the Japanese constitution, the Atomic Energy Basic Law, and the Three Non-Nuclear Principles—North Korean nuclear and missile tests have raised questions among East Asian countries about whether Japan would develop nuclear weapons. To reduce this concern, Japan should clarify its policies on four issues.
First, Japan should scale-down operations of its reprocessing plant. Rokkasho repossessing plant is designed to produce 8 tons of plutonium per year, but that is more than what Japan can plausibly use annually. So far, only two MOX reactors are operating in Japan, which means less than 2.0 tons of plutonium could be consumed annually. Since Japan already possess approximately 9.8 tons of separated plutonium at home, Japan should stop any further stockpiling.
Second, Japan should build more dry cask storages. Potentially reprocessing plant and ongoing delays in opening the plant might require utilities to store spent fuels at reactors for longer than planned until they can be transported to the Rokkasho reprocessing plant. The plant was originally expected to be completed by 1997, but is now scheduled to open by 2021. Moreover, existing spent fuel storage is approaching its maximum capacity. Once plants run out of storage space, whether dry or wet, the utilities cannot continue to operate the plant.
Third, Japan should revise its basic principles for the utilization of plutonium, perhaps to include a timeline describing methods, timing, purposes, and quantities of plutonium Japan will consume. These basic principles show transparency in the plutonium utilization plan and the purpose of use. After the Fukushima nuclear accident, the restarts have been slow: only four of Japan’s 54 original nuclear reactors came back online. To make up for the shortfall in nuclear output, Japan relied on fossil fuel imports. Moreover, this could help assuage concerns from other East Asian countries, who argue that what Japan says on peaceful usage is not enough without a clear pathway to using plutonium as a MOX fuel in the near future. Once the government clarifies a pathway, domestic and international communities could monitor plutonium supply and demand before reprocessing.
Fourth, the Spent Nuclear Fuel Reprocessing Implementation Act should be revised for a nuclear fuel cycle option. Despite the 2014 Strategic Energy Plan mentioning that Japan has flexibility on disposal because its nuclear fuel cycle will not be resolved in short-term—but likely will be in the middle- to long-term—this act describes that the purpose is constant and efficient reprocessing operations. There has been an inconsistency between words and actions. Obviously, Japan needs more time to consume its stockpile of plutonium than originally planned, and the government should revise its actions accordingly.

Like USA’s, Russia’s etc – China’s macho men need more nuclear warheads

China needs more nuclear warheads to deter US threat, military says, Commentary says the existing stockpile is big enough to prevent ‘bullying’ but should be expanded as Washington changes strategy,  SCMP, Minnie Chan, 30 January, 2018  China must expand its nuclear stockpile so it can better deter and hit back at an enemy strike as geopolitical uncertainties mount and the US appears bent on a nuclear build-up, according to the Chinese military’s mouthpiece.

In the PLA Daily on Tuesday, a commentary said China had enough nuclear weapons to prevent “bullying” by other nuclear powers but still needed to respond to changes in US strategy.

“To enhance China’s strategic counterbalance in the region and maintain China’s status as a great power, and protect national security, China has to beef up and develop a reliable nuclear deterrence capability,” it said.

It also said China would still stick to the “no first use” doctrine, meaning there were no circumstances in which it would be the first to use nuclear weapons.

The commentary comes as the administration of US President Donald Trump is expected to unveil its new military weapons policy later this week.

A leaked draft of the document says Washington will ramp up new nuclear projects and deploy more “low yield” nuclear bombs, according to the Huffington Post.

Military analysts said China was poised to increase its own arsenal of nuclear warheads but there were no plans to rival the United States.

Beijing-based military analyst Zhou Chenming said China only needed to add about 100 warheads to its stockpile to counter threats from the US and India.

“Nuclear weapons are hugely expensive to maintain and China is very pragmatic. Beijing will not spend too much money on an arms race,” Zhou said.

China has never declared the scale of its nuclear stockpile but the Washington-based Arms Control Association puts the country’s total at 270 warheads, the fourth-biggest of the five main nuclear states. Russia has 7,000, the US 6,800, France 300 and Britain 215, the association estimates. ……http://www.scmp.com/news/china/diplomacy-defence/article/2131261/china-needs-more-nuclear-warheads-deter-us-threat
