San Onofre Fairewinds NRC Presentation
/
Fairewinds Associates, in this presentation on behalf of Friends of the Earth, shows that San Onofre was operating outside of its design basis and the NRC had done nothing to address this major violation. The tube failures at San Onofre are the worst nuclear equipment failures since the near miss at Davis Bessie in 2002.

Fairewinds analysis of the triple meltdowns at Fukushima Daiichi determined that other Japanese reactor sites were also in jeopardy because their cooling water systems were destroyed by the same tsunami. In this film, Fairewinds provides evidence that cooling systems for 24 out of 37 diesel generators were shut down by the tsunami and that 14 additional nuclear reactors were impacted. Finally, Fairewinds also recommends that the criteria of the international nuclear accident scale have a Level 8 added. The addition of a Level 8 would reflect the nuclear accident scenario at a multi-reactor site that significantly changes the risk factors to the general public and emergency evacuation procedures.

Using NRC and Edison data, Fairewinds analysis determines that San Onofre had 3.7 times the number of plugged tubes than all the replacement steam generators in the US combined, and that 4,000 tubes show significant wear.

Why did replacement steam generators fail after two years, when the original generators worked for 28 years? This Fairewinds Associates Report for Friends of the Earth determines that a strategic decision by Edison to avoid a more thorough NRC licensing review process contributed to the resulting crisis.

Imprudent Design and Fabrication Decisions Caused Leaks in 2012. Cramming 377 more tubes into each replacement generator than were in the original generators held affected reliability and safety.

The Need for a Thorough Root Cause Analysis Requires No Early Restart. Fairewinds recommends that Units 2 and 3 remain shut down until a thorough Root Cause Analysis determines the cause of rapid tube failures are understood and repaired, reliability is assured, and radioactive releases are prevented.

The key causes lie in the institutional failures of political influence and industry-led regulation. The report concludes that this nuclear accident marks the end of the ‘nuclear safety’ paradigm, and exposes the deep and systemic failure of the very institutions that are supposed to control and protect people from accidents.
