Oct. 6 (Bloomberg) -- A research reactor operated by the Japan Atomic
Energy Agency was shaken beyond its design limits during the earthquake
that struck in March and another of the agency’s nuclear facilities was
likely damaged in the disaster.
The Japan Research Reactor No. 3 in Tokai
village, 115 kilometers (71 miles) northeast of Tokyo, was shaken as
much as 5.7 times more than its design allowed, the Ministry of
Education, Culture, Sports, Science and Technology said in a statement.
Parts of the roof of the experimental Japan
Materials Testing Reactor building in the agency’s research center in
Oarari, 60 kilometers from Tokyo, was damaged, possibly by the quake,
the ministry said. No radiation leaks were found at either site,
according to the ministry.
The magnitude-9 quake and subsequent tsunami on
March 11 knocked out power and cooling at Tokyo Electric Power Co.’s
Fukushima Dai-Ichi plant, causing the worst nuclear accident since
Chernobyl 25 years ago.
Neither of the Japan Atomic reactors were running
when the quake hit, said Kunimi Yoshida, an official involved in
nuclear power regulation at the science ministry.
Tokai village was the site of an accident in 1999
at a nuclear plant operated by Sumitomo Metal Mining Co.’s unit JCO Co.
Two workers were killed by radiation after pouring uranium from a
bucket into a processing tank, leading to a chain reaction.
