TOKYO, March 13 Japan's nuclear safety agency
said on Sunday there was no problem with the cooling process at
Tohoku Electric Power Co's (9506.T) Onagawa nuclear power plant
and that a rise in radiation levels there was due to radiation
leakage at another plant in a neighbouring prefecture.
The agency said a report from Tohoku Electric shows that
cooling systems at all three reactors at the Onagawa complex,
which were automatically shut after a massive earthquake and
tsunami on Friday, are functioning properly.

Fukushima Daiichi nuclear plant were damaged by the quake and
tsunami, forcing the power utility to let out air from reactor
container vessels to reduce pressure built inside.
