The Hole-in-the-Head fiasco -- a nearly complete breach of the reactor vessel closure head, or lid -- was the most infamous near-miss to a major reactor accident in the U.S. since the Three Mile Island meltdown in 1979. The Hole-in-the-Head fiasco added up to a boondoggle totaling more than $600 million.
Now it has been revealed that Davis-Besse has a hole in its Shield Building wall -- an essential component of the radiological containment structures -- that extends up to 12 inches through its 30-inch width, a full 40% way through. Davis-Besse has operated for over two years, at full power, with this potentially fatal flaw in its Shield Building wall.
The gap or air space was discovered last Thursday, and publicly revealed Friday, during the current Davis-Besse steam generator replacement project, which has breached Davis-Besse's Shield Building for an unprecedented fourth time. The previous three breaches include the pre-operational Initial Construction Opening in the 1970s; the 2002-2004 reactor lid replacement project; and the 2011 reactor lid replacement project. Each breach risks further damaging the Shield Building, where severe cracking was discovered in late 2011. In September 2013, FENOC admitted that the severe cracking is growing worse over time.
NRC Region III Staff are holding a Webinar on Davis-Besse's current steam generator replacement project on Thursday, Feb. 20th, from 6 to 7 PM Eastern. The Webinar was scheduled before revelation of the hole in the containment wall. Please pre-register and attend the Webinar. Beyond Nuclear and Don't Waste MI have generated a series of sample questions you can put to NRC during the Webinar.
Beyond Nuclear helps lead environmental coalition efforts challenging both the steam generator replacements, as well as FENOC's application for a 20-year (2017-2037) license extension at Davis-Besse. Terry Lodge, Toledo-based attorney, serves as legal counsel for the environmental coalition in both NRC proceedings.
Arnie Gundersen, Chief Engineer, Fairewinds Associates, Inc., serves as expert witness for the coalition in the "experimental" steam generator replacement intervention. Gundersen serves as expert witness for Friends of the Earth on the botched San Onofre 2 & 3 steam generator replacements, which has led to the permanent shutdown of those two reactors -- a multi-billion dollar boondoggle. Gundersen was also instrumental in outing the truth on the fatal cracking in Crystal River, FL's concrete containment, also caused by a botched steam generator replacement, another multi-billion dollar boondoggle. Gundersen has alleged that Davis-Besse's steam generator replacement has taken the same shortcuts on safety, made all the worse by its Shield Building's already very questionable, and worsening, structural integrity.
The coalition launched the challenge against the steam generator replacement in May, 2013, and defended its challenge in June and July -- twice in one month! -- 2013. The NRC Atomic Safety and Licensing Board (ASLB) which heard the intervention quickly dismissed it, without addressing the merits, effectively green-lighting Davis-Besse's shortcuts on safety. Beyond Nuclear has posted the entire docket of the steam generator intervention on its website.
The Toledo Blade and Cleveland Plain Dealer have reported that the Davis-Besse steam generator replacements will cost $600 million.
Beyond Nuclear has filed a Freedom of Information Act Request on the gap in the Davis-Besse Shield Building wall.
The Toledo Blade has reported on this story, on Feb. 14 and Feb. 15.
NRC posted an Event Notification Report on Feb. 18, and a Preliminary Notification of Occurrence (PNO) on Feb. 19.
