“The amount that came out was such an extremely small amount, so this is not a problem and it will not have an impact on the environment,” said Shinichi Morooka, professor of nuclear energy at Waseda University.

URGENT: Radiation leaks from fuel rods suspected at Tsuruga plant: local gov’t (Kyodo News)

Radiation leaks from fuel rods suspected at Tsuruga plant (Kyodo News):

FUKUI, Japan, May 2, Kyodo

Leaks of radioactive substances from fuel rods are suspected to have occurred at a nuclear power plant in Tsuruga, the Fukui prefectural government said Monday, citing a rise in the level of radioactive substances in coolant water.

The operator, Japan Atomic Power Co., will manually shut down the No. 2 reactor of the plant on the Sea of Japan coast and examine the primary cooling system for it. The local government denied that the levels of radioactive substances could threaten the nearby environment.

According to Japan Atomic, 4.2 becquerels of iodine-133 and 3,900 becquerels of xenon gas were detected per cubic centimeter Monday, up from 2.1 and 5.2 becquerels, respectively, during previous measurements conducted last Tuesday.
