OSAKA -- Two Kansai-based antinuclear groups announced Thursday that they will seek an injunction to stop Kansai Electric Power Company from burning mixed plutonium-uranium fuel at the Takahama No. 4 nuclear reactor in Fukui Prefecture later this month.

The request for the injunction was to be filed with Osaka District Court today, they said.

Green Action Kyoto and an Osaka group opposed to nuclear power in Takahama said they were taking the action because of concerns that data related to the fuel, which comes in the form of pellets, may have been fabricated.
