In 2006, the previous owner of the problem-plagued Palisades atomic reactor (see photo, left) -- Consumers Energy -- persuaded the Michigan Public Service Commission (MI PSC) to approve its sale to Entergy Nuclear. (See Consumers Energy slide from spring 2006 presentation to MI PSC.) Consumers Energy argued that it lacked the wherewithal to fix major problems -- to anneal the badly embrittled reactor pressure vessel, and to replace the age-degraded reactor lid and steam generators -- but that the new owner, Entergy, would do so.
(The steam generator replacement would be the second in Palisades' history, the first having been in 1991. Arnie Gundersen, Chief Engineer of Fairewinds Associates, Inc. and an expert witness for Beyond Nuclear and a coalition of environmental groups intervening against Palisades on safety issues, has confirmed that no other pressurized water reactor in the U.S. has replaced its steam generators twice.)
A decade after Consumers Energy told the MI PSC that Entergy would do so, none of these fixes have been made. Nor is there any plan to do so. But then again, Entergy's merchant nuclear fleet unwritten business model seems to be "Buy reactors dirt cheap, and run them into the ground!"
And U.S. Nuclear Regulatory Commission (NRC) is guilty of complicity and collusion in allowing such safety risks to fester to the breaking point.
A breach of the reactor pressure vessel due to pressurized thermal shock; a breach of the corroded reactor lid; or a cascading failure of steam generator tubes -- each of these could lead to a reactor core meltdown. Failure of containment structures, systems, and components could then cause a catastrophic release of hazardous radioactivity to the Great Lakes environment.
In 2012, the Japanese Parliament's independent investigation concluded that the root cause of the Fukushima nuclear catastrophe was collusion between industry, safety regulator, and government officials. Such collusion exists in spades at Palisades, between Entergy, the Nuclear Regulatory Commission, and government officials like U.S. Rep. Fred Upton (R-MI), who chairs the powerful U.S. House Energy and Commerce Committee, with direct oversight on NRC and nuclear safety, and in whose district Palisades is located.
Michael Keegan of Don't Waste Michigan has prepared the following docket of documentation regarding steam generator risks at Palisades:
Arnie Gundersen, Chief Engineer of Fairewinds Associates, Inc., has reviewed the NRC-Entergy communications and documentation, and concluded: "...[T]hese inspection and repair changes make it a greater risk to operate Palisades in this condition...".
With a License Amendment Request comes the opportunity for a request for public hearing.
There were some questions that the NRC did ask known as Requests for Additional Information or RAIs. Today in ADAMS [NRC's Agency-wide Documents Management System] I found Entergy's Response to those RAIs - this document has not yet been reviewed by looks to provide review of the criteria by which the tubes will be plugged or not plugged:
June 7, 2016, Entergy Palisades to NRC; SUBJECT: Response to - Palisades Nuclear Plant - Request for Additional Information Regarding the License Amendment Request for Implementation of an Alternate Repair Criterion on the Steam Generator Tubes (CAC No. MF7435) [PNP 2016-037]
The document I found today, June 20, 2016, has the ML#: ML16159A230. It is dated June 7, and was docketed June 13.
Bottom line results in increased risk to public.
The above documentation was compiled by Michael J. Keegan with Don't Waste Michigan on June 20, 2016.

CMS letter to MPSC August 18, 2006 provides reasons for selling Palisades (see pdf page 188 for Steam Generator Replacement discussion) The need to replace the Steam Generators was known in 2006 and scheduled for replacing by 2016. Exemptions now being sought in 2016 to avoid Inspections of Cold Leg Tubes permanently. Is Entergy looking to avoid having to plug additional tubes by avoiding Cold Leg Inspections?
