Gundersen Discusses the Situation at the flooded Ft. Calhoun and Cooper Nuclear Power Plants

Gundersen says “sandbags and nuclear power shouldn’t be put in the same sentence, but it is a lot better than Fukushima.” Gundersen explains that Ft. Calhoun was already shut down and has much less decay heat. He stresses that the auxiliary building and containment building are not his major concern. A small building, the intake structure, which contains the emergency service water pumps is needed for cooling the nuclear fuel and should be protected.

Another Nuclear Plant, Cooper (about 90 miles south of Ft. Calhoun), is still running and poses a bigger threat because of it’s decay heat. Gundersen believes that both Nuclear Plants will “ride out” this problem, as long as an upstream dam does not break. It an upstream dam were to break, he says, “All bets are off”.

Arnie Gundersen explains how containment vents were added to the GE Mark 1 BWR as a “band aid” 20 years after the plants built in order to prevent an explosion of the notoriously weak Mark 1 containment system. Obviously the containment vent band aid fix did not work since all three units have lost containment integrity and are leaking radioactivity. Gundersen also discusses seismic design flaws, inadequate evacuation planning, and the taxpayer supported nuclear industry liability fund.
