Tokyo: Radioactive water leaked inside a nuclear power plant in southwestern Japan but did not escape into the environment, the government has said, the latest problem for the country's nuclear industry amid an ongoing crisis at another plant.
   
The leak on Friday at Kyushu Electric Power Co's Genkai plant occurred as Japan continues its attempts to stabilise a tsunami-hit nuclear plant on its northeastern coast where three reactor cores melted and large amounts of radiation were released into the air and ocean.
   
Tetsuya Saito, spokesman for Japan's Nuclear and Industrial Safety Agency, said 1.8 tons of radioactive water leaked from a pump in Genkai's No 3 reactor, and the cause was still under investigation.
   
The water was funneled into a storage area and posed no safety risk, he said.
   
Kyushu Electric issued a statement yesterday about a pump problem but did not mention the leak. Officials at the utility were not immediately available for comment on Saturday.
   
"There have been various problems at Genkai," Saito said.
   
"But there is no safety problem as a result of what happened this time."
