Tohoku Elec finds improper nuclear data handling
TOKYO, Dec 8 (Reuters) - Tohoku Electric Power Co. Inc.
said on Friday it had found improper changes to data at
one of its nuclear power plants, but operational safety was
unaffected.
A spokesman for Tohoku Electric, Japan's fourth-biggest
utility by sales, said improper programming modified data on
coolant water temperatures at the 524,000-kilowatt No.1 unit at
its Onagawa plant in northern Japan between 1995 and 2001.
There was no falsification of data provided to the local or
central government because the modified data was not used for
reporting purposes, he said.
Tohoku's announcement came days after Tokyo Electric Power
Co. (TEPCO) , Japan's largest utility, said it had found
data modification that occurred in 1985 and 1988.
TEPCO faced stiff criticism after it came to light in 2002
that it had falsified nuclear safety inspection data for more
than a decade.
