Docket of Beyond Nuclear and coalition interventions against Entergy Nuclear's Palisades atomic reactor
First intervention proceeding, Dec. 1, 2014 to present
(Entergy applied for alternate fracture toughness regulatory relief, under 10 Code of Federal Regulations 50.61(a), because it can't meet the standard regulation 10CFR50.61, after 2017 for neutron radiation bombardment induced embrittlement of the reactor pressure vessel, and thus pressurized thermal shock risks -- a meltdown risk. The risk is brittle through-wall fracture.)
Intervention by Beyond Nuclear, Don't Waste MI, Michigan Safe Energy Future--Shoreline Chapter, and NEIS, filed Dec. 1st, 2014.
Beyond Nuclear issued a press release on Dec. 2nd.
Beyond Nuclear also posted an entry on its website, with links to additional background information.
Second intervention proceeding, March 9, 2015 to present
(Entergy applied for regulatory relief under an "Equivalent Margins Analysis" under 10CFR50, Appendix G, because certain parts of its reactor pressure vessel at Palisades will fall below the Charpy V-Notch Upper Shelf Energy 50 foot-pounds screening criteria for metal degradation, as early as 2016. The risk is of through-wall "ductile tearing."):
On March 9, 2015 the coalition opened a second front in the safety regulation battle, filing an intervention petition and hearing request regarding the parallel issues of Entergy Palisades' "Equivalent Margins Analysis." This attempt by Entergy at yet another weakening of regulations is due to the "Charpy V-Notch Upper-Shelf Energy" of RPV plates and welds at Palisades falling below NRC's 50 ft.-lb. safety screening criteria. In addition to refiling Gundersen's December 1, 2014 expert witness declaration, Lodge also cited a recent Greenpeace International report, warning that extensive cracking of RPVs in Belgium raises a red flag for similar cracking occurring worldwide. Greenpeace Belgium also issued a press release.
Beyond Nuclear posted a March 10 web entry about the March 9 filing. Although it repeats a lot of the same info. as immediately above, it does provide some additional background/context.
April 3, 2015 NRC staff and Entergy oppositional responses to our March 9 filing.
Beyond Nuclear et al. filed a rebuttal to NRC's and Entergy's responses on April 10, 2015.
And, for historical context, and lest we forget, a broad environmental coalition fought the 20-year license extension at Palisades. That proceeding was back in 2005-2007. Embrittlement of the reactor pressure vessel/pressurized thermal shock risks of meltdown and catastrophic release of hazardous radioactivity was the single greatest safety concern (of a long list of concerns) back then, as well. This campaign is chronicled on the NIRS website.
