We told 'em so. Despite widespread resistance, NRC rubberstamped Palisades' 20-year license extension in 2007.
As shown at the U.S. Nuclear Regulatory Commission's (NRC) "Current Power Reactor Status Report", Entergy's Palisades atomic reactor in Covert, Michigan on the Lake Michigan shoreline is at zero percent power. Why? Because, yet again, it has suffered a leak and breakdown -- but the latest of many in recent years.
As reported at the NRC Event Notification:
"TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO COMPONENT COOLING WATER TRAIN OUT OF SERVICE
'At 2030 hours [EST] on February 14, 2013, technical specification (TS) 3.7.7 condition A was entered due to the right train of the component cooling water (CCW) system being declared inoperable. The cause of the inoperable train was the identification of an approximate 40 gallon per hour CCW system to service water system leak inside the 'A' CCW heat exchanger. TS 3.7.7 condition A requires restoration of the inoperable train within 72 hours. If the restoration is not completed within 72 hours, the plant must be in Mode 3 within 6 hours and in Mode 5 within the subsequent 36 hours.'
'Due to the inability to repair the leak within the required 72 hour time frame during power operation, a plant shutdown was initiated at approximately 1300 hours on February 15, 2013. Entry into Mode 3 is expected at approximately 1700 hours on February 15, 2013. The plant will enter Mode 5 to execute leak repair. Mode 5 entry is expected at approximately 0800 hours on February 16, 2013.'"
No explanation is given as to why this incident, dated Feb. 14, was not publicly reported until Feb. 19.
However, NRC Region 3 spokeswoman Viktoria Mytling told WSBT-TV in South Bend, IN that "NRC resident inspectors at Palisades have been aware of a leak from the cooling water system and followed the plant’s actions to find the location after the leakage increased from 2 to 35 gallons an hour in less than a week."
No explanation is given for the disparity between Mytling's 35 gallon per hour figure, and the NRC incident report's 40 gallon per hour figure, above.
The Kalamazoo Gazette quotes Mytling as admitting that the leakage began as early as Feb. 8. NRC has provided no explanation as to why the public was not informed about the problem for 11 days.
(Last year, U.S. Rep. Dennis Kucinich (D-OH) demanded an NRC investigation into Mytling's downplaying of a reactor leak at the troubled Davis-Besse atomic reactor near Toledo. In addition, Chicago watchdog group Nuclear Energy Information Service, via a Freedom of Information Act Request to the State of Illinois Dept. of Nuclear Safety, documented that Mytling's flip assurance -- that a radioactive steam leak at the Byron atomic reactor must have contained exceedingly low levels of hazardous radioactive tritium, as radiation monitors had not detected any -- was baseless and misleading, as no real-time tritium monitoring capability existed at the plant.)
However, an 11 day delay in informing the public is nothing new, in light of Entergy and NRC behavior at Palisades in recent years. For example, in June, 2012, courageous Palisades whistleblowers and their attorney, Billie Pirner Garde of Washington D.C., working with U.S. Rep. Ed Markey (D-MA), made public a leak into Palisades' safety critical control room (where electrical circuitry and equipment cannot be allowed to get wet) that had been ongoing for more than a year, with leakage being caught in buckets near the central control panel. That leak had been kept not only from the public, but even from the NRC's Chairman, despite his tour of the problem-plagued plant on May 25, 2012. NRC internal investigations supposedly continue as to why the agency's own chairman was kept in the dark about the control room leak.
WSBT has also posted an additional NRC statement about the latest "leak per week" (a phrase coined by watchdogs on Entergy's controversial and troubled Vermont Yankee atomic reactor) at Palisades:
"NRC STATEMENT: WHAT IS THIS LEAK ALL ABOUT?
The leak came from the component cooling water system whose function is to remove heat from pipes, pumps and other equipment running at high temperatures. Workers identified the source of the leak to be one of the plant’s two heat exchangers which are a part of this system. Heat exchangers, which consist of about 2,000 tubes each, are used to remove heat during normal operation but also during potential accident scenarios. Palisades has two heat exchangers, which cool equipment important to safety, and are required to be in working condition. According to NRC regulations, if there is a problem with one of the heat exchangers it would need to be fixed within in [sic] 72 hours. If that’s not possible the plant would have to shut down to find and fix the leak. Palisades made the decision to shut down before reaching the established limit. The plant has to repair the heat exchanger before returning online.
NRC resident inspectors, in consultation with our expert in the region, continue to monitor [sic] situation." (Emphasis added.)
Thus, this equipment breakdown does have safety significance.
The Holland Sentinel was perhaps the first news outlet to report on this story.
