Chief Nuclear Engineer Arnie Gundersen: The Implications of the Fukushima Accident on the World’s Operating Reactors – Siemens Report: Fukushima Unit 4 Spent Fuel Pool Cracked From Earthquake

Added: 23.05.2011

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.
