Update, Japan

By Simon Lomax
March 16 (Bloomberg) — U.S. Nuclear Regulatory Commission
Chairman Gregory Jaczko said all the water has drained from the
spent-fuel pool at a crippled nuclear reactor in Japan,
resulting in the release of high levels of radiation.
“We believe that the secondary containment has been
destroyed and there is no water in the spent-fuel pool,” Jaczko
said today at a hearing of a House Energy and Commerece
Committee panel.
The unit at the Fukushima Daiichi plant wasn’t operating at
the time of the March 11 earthquake and tsunami, Jaczko said.
The spent-fuel pool at the plant’s Unit 3, which was in
service, may be cracked and losing water, Jaczko said.
