Tokai radioactive leak contained


A radioactive leak Monday raised the alert at a nuclear fuel-reprocessing plant in Tokai, Ibaraki Prefecture, but did not pollute the outside atmosphere, the prefectural government said.

A wall surface of an analyzing facility at the plant registered 555 becquerels of radiation per square centimeter, more than 100 times the level at which the plant is required to restrict entry, the local government said.

The Japan Nuclear Cycle Development Institute, the plant’s operator, informed the prefectural government of the incident.

The radioactive leak was contained within the plant and did not pollute the outside atmosphere, it claimed.

The institute said it was investigating the cause of the leak.
