Water leaks at Japan's Onagawa nuclear plant --Aftershock splashes water from fuel pools at 3 reactors --'Small' rise in radiation levels inside reactor buildings 08 Apr 2011 Water leaked out of spent fuel pools at the Onagawa nuclear plant in northeast Japan after a strong aftershock rocked the region late on Thursday, but there was no change in the radiation levels outside the plant, operator Tohoku Electric Power Co said on Friday. It said water sloshed out of spent fuel pools in the plant's No.1, No.2 and No.3 reactors, which had been shut down after the earthquake on March 11, and had also leaked in three other locations in the No.3 reactor complex.
