Two Nuclear Reactors Were Damaged by the Earthquake, BEFORE the Tsunami Hit ... and the Entire Nuclear Reactor Design Is Flawed

George Washington's picture

Bloomberg reported last week:

radiation alarm went off at Tokyo Electric Power Co.’s Fukushima
nuclear power plant before the tsunami hit on March 11, suggesting that
contrary to earlier assumptions the reactors were damaged by the
earthquake that spawned the wall of water.


A monitoring post on
the perimeter of the plant about 1.5 kilometers (1 mile) from the No. 1
reactor went off at 3:29 p.m., minutes before the station was
overwhelmed by the tsunami that knocked out backup power that kept
reactor cooling systems running, according to documents supplied by the
company. The monitor was set to go off at high levels of radiation, an
official said.

Nuclear expert Arnie Gundersen just confirmed that some of the Japanese nuclear reactors were severely damaged even before the tsunami hit.

Gundersen reports that the containment vessel at Fukushima 1 started
leaking and melting down before the tsunami hit. Similarly, Gundersen
notes that the fuel pool at reactor 4 cracked and started leaking after
the earthquake and before the water hit.

Remember that Japanese seismologists had warned for years that Japan's reactors were extremely vulnerable to earthquakes, with one top seismologist noting:

It's like a kamikaze terrorist wrapped in bombs just waiting to explode.

also points out that Florida's nuclear reactors are vulnerable to tidal
surges from hurricanes, and California's reactors vulnerable to tidal
surges caused by earthquakes.

And he notes that the attempt to release pressure at Fukushima failed 3 out of 3 times: 100% failure rate.

Gundersen notes that this shows that the entire design of these old-fashioned nuclear reactors is a failure.

Finally, Gundersen says - I've repeatedly noted - that conditions are in many ways even more precarious in the U.S. than in Japan.
