Construction in Aomori Prefecture of the world's first commercial reactor to operate solely on plutonium-uranium mixed oxide fuel will be pushed back for the third time due to prolonged safety checks, the utility building the reactor said Tuesday.
Electric Power Development Co. had been planning to begin construction of major facilities at the Oma nuclear power plant in the prefecture during the latter half of this year, but told the Oma Municipal Assembly on Tuesday it has decided to delay the work by about two years. The delay means the new target for the reactor to begin operations is fiscal now 2026.
The move clouds the course of Japan's policy for the nuclear fuel cycle, in which the reactor was supposed to play a key role. Mixed oxide (MOX) fuel is produced by extracting plutonium from spent nuclear fuel and mixing it with uranium. Tokyo is also under international pressure to slash its stockpile of plutonium, which has the potential to be used to produce nuclear weapons.
