Japan’s nuclear regulatory body says the Tomari nuclear power plant in Hokkaido is using emergency generators to cool fuel after the region was hit by a powerful earthquake. The plant’s operator Hokkaido Electric Power Company says all 3 channels from outside power sources were cut off about 20 minutes after the quake struck early Thursday. The plant’s 3 reactors are all currently offline, with a total of 1,527 fuel assemblies in its storage pools. Following the quake, 6 emergency diesel-powered generators automatically switched on to cool the nuclear fuel. No changes in storage pool water levels or temperature have been reported. The Nuclear Regulation Authority and Hokkaido Electric say it is not yet clear when outside power sources will be restored, with all thermal power plants in Hokkaido currently shut down.

The Tomari Nuclear Power Station suffered a power outage but was cooling its fuel rods safely with emergency power, Chief Cabinet Secretary Yoshihide Suga said. Operator Hokkaido Electric Power Co. reported no radiation irregularities at the plant, which has been shut since shortly after the 2011 Great East Japan Earthquake, Suga told a news conference.

The Japanese government has pushed for the reuse of mixed-oxide (MOX) fuel in the country’s nuclear reactors, but utilities that finance the reprocessing have not funded those operations since fiscal year 2016, according to financial reports released by the power companies on September 2. Japan’s KYODO News reported that sources said 10 utilities, including Tokyo Electric Power Company and Japan Atomic Power Co., stopped setting aside funds for reprocessing costs because of what Kyodo said were “huge expenses” to build reprocessing facilities. Japan’s government updated the country’s Basic Energy Plan earlier this year after its first review in four years. The new plan includes a pledge to reduce the country’s stockpile of plutonium extracted from spent nuclear fuel, which reportedly came after the U.S. expressed concern about Japan’s stockpile. Japan is the only country without nuclear weapons with the authority to reprocess spent nuclear fuel. The energy plan outlined in July for the first time also allowed utilities to consider spent MOX fuel as nuclear waste, which has brought debate about how to deal with it.
