Interim Storage Facility Starts Its Operation

To start operation of an interim storage facility of spent nuclear fuels, Aomori Prefecture, City of Mutsu and the operator reached an agreement for safety, which would be a condition for carrying the fuel into the facility. It will be the first case for spent nuclear fuels in Japan to be stored outside the site of nuclear power plant. Since the agreement determines that the storage is limited for fifty years, the government of Japan needs to find somewhere for the final storage.

There are 18 thousand metric tons of spent nuclear fuels, which were produced from nuclear power plants in Japan. They are stored in each nuclear power plant, since there is no facility in Japan for final disposal of those fuels. However, the government of Japan promotes project of recycling the fuels, the first factory for reprocessing spent nuclear fuels in Rokkasho Village in Aomori, which construction started in 1993, has yet completed due to technological troubles.

 

The government of Japan decided to build an interim facility for spent nuclear fuels which had been kept on increasing with nuclear power generation. City of Mutsu expressed its willingness to accept the facility. But, the facility was built in 2013. However, it has not been operated due to prolonged inspection of Nuclear Regulation Authority or necessity of additional measures for safety.

 

The Governor of Aomori Prefecture, Soichiro Miyashita, a former mayor of Mutsu City, announced acceptance of carrying the nuclear fuels into the facility in Mutsu in July. Aomori Prefecture, Mutsu City and Recyclable-Fuel Storage Company, the operator of the interim storage facility, exchanged safety agreement in August. It is likely that the first spent fuel will be brought from Kashiwazaki-Kariwa Nuclear Power Plant in September.

 

The greatest concern of the residents in Aomori is whether the nuclear wastes brought in will really be taken out to somewhere else within fifty years. While the fuels are supposed to be sent to the reprocessing factory in Rokkasho village, there is no perspective about when the factory will start its operation. There are some views of experts that recycling project of spent nuclear fuels are already bankrupted. If the government cannot find the place for sending the stored fuels, it is possible that the facility in Mutsu will not only be an interim but permanent storage facility.

 

The same kind of concern exist in Fukushima. Two local governments accepted to build an interim facility for nuclear waste, including soil in Fukushima contaminated by emission of radioactive ashes from exploded Fukushima Daiichi Nuclear Power Plant, with a promise of sending the waste out to somewhere else within thirty years. The government of Japan has not found the final place for the nuclear waste to go. It is notable that the government started discharging “processed” water into the Pacific Ocean, when it could not, or refused to, find the place for storage anymore.

Amendment of Local Autonomy Law

The House of Representatives started discussion on revision of the Local Autonomy Law, which would vest the national government a power to instruct local government in an emergency. It may change the relationship between the national and local government, which has been recognized as equal. The opposition parties oppose the amendment, arguing that it would give the national government an excessive power.   With the Meiji Restoration, the national government abolished the feudal system, introducing modern governance. However, its autonomy was not sufficient. The governor of each prefecture was appointed by the national government. The local governments subordinated to the national government. It was as late as 2000 when  the Comprehensive Decentralization Law  was enacted and the relationship between the national and local government was defined as equal.   The national government found inconvenience in the relationship between the national and local government, when COVID-19 was preval

Request for Final Nuclear Disposal Site

Ministry of Economy, Trade and Industry requested Genkai Town, Saga, to accept “literature survey” for building a final disposal site for high-level radioactive waste. Genkai is going to answer within this month. If it accepts, it will be the third place to accept that survey, following two places in Hokkaido. Main reason to accept the survey is supposed to be subsidy from the national government.   Japan has no final disposal site. Among all 54 reactors in 17 nuclear power generation plant, 12 reactors of 6 plants are operating. The rest of them are not in operation, some of which are determined to be decommissioned. Used nuclear fuels are stocked in each plant, 　 or have sent to a reprocessing plant in Rokkasho, Aomori. There are two plans to stock nuclear wastes in the intermediate facility for disposal, one is already built and another is still in negotiation.   Nuclear Fuel Final Disposal Act in 2000 determines to bury nuclear waste in the underground. Literature survey, which is

Death Penalty Demanded on Criminal of Arson

On the historically brutal case of arson, the public prosecutors demanded an ultimate penalty to the offender. In the trial on the arson and murder in Kyoto Animation in 2019, the prosecutors requested death penalty on the defendant, Shinji Aoba. The lawyers of Aoba argued that the court should avoid sentencing death penalty. The judgement will be passed next January. Aoba was indicted as putting fire after pouring gasoline in the building of Kyoto Animation (Kyoani), a studio producing animation works, and killed 36 staffs and injured 32 on July 18 th , 2019. In the trial, Aoba argued that he could not tolerate Kyoani, because it had stolen his novel story in its works. Aoba later apologized to the victim’s families that he had done too much and regretted it.   In the closing argument in Kyoto Regional Court, the prosecutors demanded death penalty for Aoba, because the number of victims were extremely high in the history of criminal trials in Japan. “It is hard to describe about how t
