Ibaraki's governor blocks the second stage of a nuclear waste survey

Ibaraki Governor Kazuhiko Oigawa said on Friday he will not consent to a preliminary survey for a final disposal site for high-level nuclear waste. The preliminary survey is the second of three stages. It cannot proceed without the prefectural governor. His refusal stops the process at the city line, even if a mayor has already said yes to the first stage.

That yes came on Wednesday. Sadayuki Suzuki, mayor of Hitachiomiya, said his city will accept a literature survey, the paper stage that opens the selection. On Friday, after Oigawa's press conference in Mito, Suzuki said he saw the situation differently from the governor. The two statements leave Hitachiomiya in a position Japan' s disposal law allows and then frustrates: a municipality can volunteer for the literature survey, and the governor can refuse the only stage that requires his signature.

Oigawa was plain. He said he did not plan to give his approval, that his position would not change, and that he was also ruling out the idea of hosting a disposal facility in the prefecture at all. He did not limit the refusal to Hitachiomiya. He closed the prefecture.

Tokai, and the burden argument

The reason he gave is cumulative. Ibaraki already hosts Japan Atomic Power Company's Tokai No. 2 plant, in the village of Tokai. Oigawa said the prefecture had contributed to national energy policy by shouldering that burden, and that the balance between benefits and burden was off. He added that areas without nuclear plants should be considered for a final disposal site first.

Tokai has a particular place in Japan's nuclear history. The village held the country's first commercial plant. Tokai No. 2 is a later boiling-water reactor on the same coast, and it has spent years in the restart argument after the 2011 Fukushima disaster. A governor who cites it as reason enough to refuse a waste survey is saying that spent-fuel risk and waste-repository risk should not stack in the same prefecture. The disposal programme's design assumes some community, somewhere, will take the repository. Oigawa's formula pushes that community toward prefectures that never generated the waste.

The three stages are literature, preliminary survey, and detailed investigation. Only the second needs the governor. A literature survey can therefore begin in Hitachiomiya on Suzuki's consent and produce a report that has nowhere to go if Oigawa is still in office when it finishes. That is the practical effect of Friday's sentence. It does not cancel Wednesday's. It caps it.

A mayor and a governor, two days apart

Suzuki's Wednesday announcement was the kind of local yes the national programme has struggled to collect. Mayors who volunteer face voters who do not. A governor's no, delivered at a press conference and tied to an existing plant, gives those voters a prefectural cover and gives the mayor a public split. Suzuki did not withdraw the literature survey on Friday. He said he saw it differently. The file can sit at stage one for as long as the city wants to pay the political cost of a survey that cannot advance.

Oigawa also shut the door on a later change of mind. He said his position would not change. Governors can be replaced. This one has put the refusal on the record before any preliminary survey papers are drafted. For the national programme, Hitachiomiya is now an example of the veto the law built in: a city can open the book, and the prefecture can close it.
