Junko ENDO for Mayor, Rokkasho village, Aomori Prefecture!!

(About Rokkasho Nuclear Fuel Cycle Center and Rokkasho Village Mayor election, please look here)

Who is she?


She was born on July 3, 1959 at Kushiro (Hokkaido).

She graduated from Muroran Institute of Technology (Hokkaido) and from the Faculty of Medicine, Hirosaki University (Aomori Prefecture).

She is a Certified Physician of the Japan Nuclear Medical Society (PET Nuclear Medicine),

and Certified Industrial Physician of the Japan Medical Association.

Currently, she is a Part-time lecturer at Tsugaru Health Cooperative, Kensei Hospital.

She is married with a daughter and two adorable cats.

As a doctor, Ms Junko ENDO has been particularly interested in health hazard issues. She points out the increase in childhood leukemia cases around the reprocessing plants of La Hague in France and of Sellafield in the UK, as well as the increase in congenital disorders and childhood leukemia cases near CANDU reactors in Canada, which generate tritium.

She proposes to create a multi-disciplined committee of experts to gather the latest information on tritium’s impact on living organisms and also to reexamine the biological and environmental impacts of radioactivity generated by the nuclear fuel cycle, especially from fuel reprocessing. Scientifically observed negative health and environmental hazards could lead to reexamining the practicalities of the nuclear fuel cycle.

She is also for the protection of the important primary local industries such as fishing, agriculture and forestry products. Releasing more than 10 quadrillion Bq per year in the ocean will tremendously impact fishing. By protecting the environment from the damages caused primarily by the reprocessing plant, she proposes to protect other industries as well.

Rokkasho village is known for its high suicide rate, including younger people. She is for promoting a village friendly for psychologically, physically and socially fragile people.

Ms Endo is for promoting a better mutual communication and support system between citizens and medical workers. Improving work conditions of medical professionals is urgent to prevent the total collapse of the medical system.

Currently, all the members of Rokkasho village local assembly are male. It is difficult to hear female voices. Ms Endo would work for a system to listen to women, and integrate their thoughts and views in village policy. She will also try to improve the local political environment by increasing female local assembly members.

A brief historical and geographical reminder

There is a nuclear fuel cycle center in Rokkasho village, located at the root of Shimokita Peninsula in Aomori Prefecture, situated in the northernmost part of the main island of Japan.

On April 9, 1985, the governor of Aomori Prefecture decided to accept the center, composed of three facilities:

  • a uranium enrichment (note 1) plant,
  • a fuel reprocessing plant,
  • and a low-level radioactive waste repository.

Afterwards, two facilities have been added:

  • a temporary storage facility of high-level radioactive waste returned from overseas after reprocessing,
  • and a MOX (note 2) fabrication plant.

Who is operating the nuclear fuel center?

This nuclear fuel cycle center of Rokkasho village is operated by Japan Nuclear Fuel Limited (JNFL), notorious for its incompetent management to say the least. In October 2017, Japanese Nuclear Regulation Autority (NRA) reported that JNFL violated safety measures. See a Mainichi Shimbun article below:

Unfinished nuclear fuel reprocessing plant faked safety records: NRA (Mainichi Shimbun, October 11, 2017)

” The NRA concluded on Oct. 11 that Japan Nuclear Fuel Ltd. (JNFL) has violated safety measures after it was learned that the firm failed to carry out the required checks and nevertheless continued to write down “no abnormalities” in safety check records. There has been a spate of incidents such as the flow of rainwater into facility buildings at the plant in the Aomori Prefecture village of Rokkasho.

The plant, which is scheduled to reprocess spent nuclear fuel, was on the verge of hosting a final-stage NRA safety inspection, but the checkup is likely to be postponed considerably as JNFL now has to prioritize in-house inspections of all facilities at the plant. ”

Major problems of the Rokkasho reprocessing plant

 The Japanese nuclear fuel cycle collapsed with the fast breeder reactor “Monju”

The Japanese government persisted to continue research and development on the fast breeder reactors, even though they had been abandoned elsewhere in the world. It was in December 2016 that the government decided to finally decommission the prototype reactor “Monju”.

The government is still trying to start the operation of the Rokkasho reprocessing plant in the first half of 2021 fiscal year, even though the prospect of the fast breeder reactor’s commercialization has become improbable. There is a contradiction here. Why start a reprocessing plant when there is no usage plan for the end product (see below as for Mox fuel usage)? One possible reason is that for quite a while former Liberal Democratic Party (LDP) ministers have been hinting at the possibility to possess nuclear weapons. They may want to have such a plutonium extraction plant which can produce eight tons of plutonium annually.

Surplus Plutonium problem

The Japanese government has ordered the power companies to reprocess the total amount of used nuclear fuel resulting from nuclear power plants’ operation. When there was no reprocessing plant in Japan, the reprocessing was entrusted to the UK and France. After that, a national reprocessing plant was built in Tokai village in Ibaraki prefecture, and then the construction of the private reprocessing plant in Rokkasho village in Aomori Prefecture was started in 1993.

The total amount of plutonium remaining in these reprocessing plants is about 48 tons. Since the commercialization of the fast breeder reactor has become improbable, the government wants to use the plutonium as MOX fuel at nuclear power plants (called plu-thermal in Japan).

However, since the TEPCO Fukushima Daiichi nuclear accident of March 11, 2011, the plu-thermal project is not progressing and it has become difficult to use up the surplus plutonium. If the Rokkasho reprocessing plant is put in operation, it will create a surplus of eight tons of plutonium annually. The possession of such an amount of plutonium will most certainly increase tensions in Asia.

Risks involved in the Rokkasho plant

① The reprocessing plant is on a fault
Japan is riddled with geological faults, and there is no stable stratum. The Rokkasho reprocessing plant is not on a stable stratum at all. A big active fault of about 100 km lies in the Pacific Ocean side. Scientists warn that in case of a big earthquake, a magnitude 8 tremor could seriously damage the reprocessing plant.
The operating company insists that a big earthquake will not occur in Rokkasho, but their seismograph is installed on bedrock, and is set so that it does not indicate more than a seismic intensity 3. Why? It is because when a seismic intensity higher than 3 is detected, it is necessary to make a total inspection of the reprocessing plant.

② Hakkoda and Towada volcanoes are nearby
Recently, Hakkoda Mountain and Lake Towada, major tourist destinations in Aomori Prefecture not far from the plant, came to be monitored as possible origins of a volcano-related catastrophe.
With a volcanic eruption, cinders and volcanic ash can fall thick in the vicinity of the reprocessing plant. This may make it difficult to secure external power supplies, to drive emergency power vehicles, and/or to secure cooling water. In addition, if the small volcanic ash can clog filters and destroy equipment.

③ Fighter jets fly near Rokkasho
Within 30km of the Rokkasho reprocessing plant, lies Misawa Airbase used by the US Air Force and Japanese Air Self Defense Force. There is also the Amagamori bombing exercise ground within 10km. Fighter jets exercising in Amagamori fly over the Ogawara port, passing through the vicinity of the reprocessing plant to repeat the training.
There is no doubt that a major disaster will occur if a fighter plane crashes into the reprocessing plant. Considering that the reprocessing plant is planned to go into operation in the coming years, it is very unlikely that the US Misawa Airbase and exercise ground would be relocated before the reprocessing operation begins.

Possibility of a serious accident

In the reprocessing project application submitted by JNFL, the following list cites as possible serious accidents:

① criticality in the dissolution tank,
② criticality by a transfer error of the solution containing plutonium,
③ evaporation to dryness by the loss of the cooling function,
④ explosion caused by hydrogen generated by radiolysis,
⑤ an organic solvent fire in a cell of the plutonium refining facility,
⑥ the damage to the used fuel aggregates in the fuel storage pool,
⑦ leakage from piping of liquid high-level radioactive waste storage facilities to cells.

If any of these major accidents occur simultaneously, or if the accident is triggered by a crash of a fighter plane or a volcanic eruption, the scale of the accident would be more than prepared for. However, the range of nuclear disaster prevention of the reprocessing plant is limited to a radius of 5 km only.

When the plant goes into operation, even without an accident, radiation exposure of the entire Aomori prefecture and of the Pacific Ocean will be far too high

After the Fukushima Daiichi nuclear accident, many tanks were created on the site of the Fukushima nuclear power plant to store the tritium contaminated water after processing the radioactive water by the multi-nuclide removal facility (Advanced Liquid Processing System = ALPS). In Fukushima prefecture, tritium contaminated water is not discharged in the ocean because of the opposition of fishermen, while in Rokkasho the same tritium water was released in a large amount during the active testing. Fishermen in Iwate once required that the reprocessing plant drainage be discharged in Mutsu Bay and not in the Pacific Ocean. The person in charge in Aomori Prefecture refused, saying, “Mutsu Bay would die”.


Because of all these risks which involve not only Rokkasho village or Aomori Prefecture but the whole world, we need the village mayor who says NO! to Rokkasho Nuclear Fuel Center.
