Japanese nuke fire slightly hurts 1

KASHIWAZAKI, Japan, March 5 (UPI) -- A fire at an underground cooling pump of a Japanese nuclear plant caused minor burns to a worker but no radioactive leakage, officials said.

The incident occurred in the No. 1 reactor of the Kashiwazaki-Kariwa plant in Kashiwazaki, Niigata Prefecture, the Kyodo news agency reported.

Work has been suspended at the reactor and six others since a 2007 earthquake, Tokyo Electric Power Co said.

The fire, the eighth during the checkups since the suspension, was extinguished in about 30 minutes. Firefighters suspect an organic solvent caused it.
