TEPCO
unable to locate source of leak in Fukushima reactor

December, 2012
The
operator of the Fukushima No. 1 nuclear power plant is grappling to
locate the source of a leak of highly radioactive water in the
crippled No. 2 reactor, and will continue trying to pinpoint the
cause next week.
A
remote-controlled robot is now scouring the basement of the reactor
building that houses the pressure suppression chamber to pinpoint the
cause of the leak.
Tokyo
Electric Power Co. said it was unable to identify the source of the
leak when the robot inspected one of the eight vent pipes that
connect the chamber with the containment vessel on Dec. 11.
TEPCO
suspects the radioactive water is leaking from fractures near the
pressure suppression chamber.
It
was the first detailed inspection near the chamber.
Nuclear
fuel in the No. 2 reactor melted following the earthquake and tsunami
disaster last year.
A
huge volume of highly radioactive water, used to cool down the fuel,
has since been leaking from the reactor, TEPCO said.

Japan
Atomic Power Co. may have to decommission one of its reactors after
seismologists concluded the plant is sitting over an active fault
line, potentially the first permanent shutdown of a nuclear unit in
Japan since the Fukushima disaster last year
