Nuclear: Leaning Tower of Vogtle: Arnie Gundersen & Libbe HaLevy of Nuclear Hotseat

Nuclear: Leaning Tower of Vogtle: Arnie Gundersen & Libbe HaLevy of Nuclear Hotseat

In this prescient interview with Nuclear Hotseat host, Libbe HaLevy, Arnie goes over the problems at the Vogtle nuclear reactor construction in Georgia, where the weight of the unit is already causing it to sink into Georgia’s red clay. Arnie analyzed the data that became the basis for the Blue Ridge Environmental Defense League (BREDL)’s petition…

More Lessons From the Fukushima Daiichi Accident: Containment Failures and the Loss of the Ultimate Heat Sink

More Lessons From the Fukushima Daiichi Accident: Containment Failures and the Loss of the Ultimate Heat Sink

In this Monday's video, Fairewinds investigates a recently released report from Tokyo Electric. Arnie Gundersen discusses TEPCO's latest analysis that, almost two years after the accident, fully substantiates Fairewinds long held position that the explosion at Fukushima Daiichi Unit 3 was the result of a detonation shock wave. Arnie also discusses troubling reports that the Nuclear Regulatory Commission has been avoiding the analysis of damage to many nuclear plants' emergency cooling systems (Ultimate Heat Sink) from storm surges, tsunamis or dam failures. The ramifications of both of these issues on old designs and also the AP1000 are also analyzed in depth.

Fukushima and Its Impact Upon the Westinghouse-Toshiba Designed AP1000 Atomic Power Plant

Fukushima and Its Impact Upon the Westinghouse-Toshiba Designed AP1000 Atomic Power Plant

Fairewinds was retained by the AP1000 Oversight Group to evaluate the AP1000 design for flaws that are now evident as a result of the nuclear accidents at Fukushima. The NRC’s refusal to thoroughly examine these flaws is reminiscent of the Atomic Energy Commission’s refusal in 1972 to thoroughly examine the innate flaws in the GE Mark 1 containment systems that failed at Fukushima. The AP1000 Oversight Group is demanding that these design flaws be remedied prior to design certification, lest history repeat itself.

Nuclear Containment Failures: Ramifications for the AP1000 Containment Design

This report combines the oral testimony of Arnie Gundersen to the NRC ACRS with previous Fairewinds reports on AP 1000 containment, adds new evidence and consequences of that evidence, addresses erroneous information provided to ACRS by the NRC staff in October 2010, and addresses additional misconceptions.
