With communities refusing to come forward to host the by-product of Japan’s nuclear energy industry, the Japanese government is drawing up a map of the most suitable locations for underground repositories.

The original proposal for a repository for the waste from the nation’s nuclear energy sector was first put forward in 2002, but even then there were few communities that were willing to be associated with the dump. Fifteen years later, and with a number of Japan’s nuclear reactors closed down for good in the wake of the Fukushima accident, the need for a permanent storage site is more pressing than ever.
The disaster at the Fukushima Dai-ichi nuclear plant is still fresh in the memory of the Japanese public
Radioactivity release
The disaster, in which a 13-meter tsunami triggered by an off-shore earthquake crippled four reactors at the plant and caused massive amounts of radioactivity to escape into the atmosphere, also underlined just how seismically unstable the Japanese archipelago is and the need for the repository to be completely safe for 100,000 years.
Aileen Mioko-Smith, an anti-nuclear campaigner with Kyoto-based Green Action Japan, does not believe the government can deliver that guarantee.
“You only have to look at what happened in 2011 to realize that nowhere in Japan is safe from this sort of natural disaster and it is crazy to think otherwise,” she told DW.
Given the degree of public hostility, Mioko-Smith believes that the government will fall back on the tried-and-trusted tactic of offering ever-increasing amounts of money until a community gives in.

The security requirements of the facility will be exacting, the government has stated, and the site will need to be at least 300 meters beneath the surface in a part of the country that is not subject to seismic activity from active faults or volcanoes. It must also be safe from the effects of erosion and away from oil and coal fields. Another consideration is access and sites within 20 km of the coast are preferred.
High-level waste
The facility will need to be able to hold 25,000 canisters of vitrified high-level waste, while more waste will be produced as the nation’s nuclear reactors are slowly brought back online after being mothballed since 2011 for extensive assessments of their safety and ability to withstand a natural disaster on the same scale as the magnitude-9 earthquake that struck Fukushima.

When it is released, the government’s list is likely to include places in Tohoku and Hokkaido as among the most suitable sites, because both are relatively less populated than central areas of the country and are in need of revitalization efforts. Parts of Tohoku close to the Fukushima plant may eventually be chosen because they are still heavily contaminated with radiation from the accident.
