Jellyfish attack on Japanese nuclear reactor eases

A Japanese nuclear reactor that slowed down when jellyfish partly blocked a seawater intake resumed normal operations on Friday, operator Chugoku Electric Power Co said.

Output from the 820 megawatt reactor fell to 770mw on Thursday after the jellyfish partly covered the entrance of a seawater supply pipe, the Hiroshima-based utility said.

A fall in the number of jellyfish enabled the No 2 reactor at its sole Shimane plant return to operating at full capacity on Friday, it said.
