USA’s Nuclear Regulatory Commission gambles with safety, using legalistic jargon

US NRC Playing Brazen Legalese Games with Safety (Reactor Pressure Vessel Embrittlement) at Palisades Nuclear Power Station and Elsewhere, Mining Awareness, 9 Apr 15  In the April 18, 2013 US NRC “Summary of the March 19, 2013 Public Meeting Webinar Regarding Palisades Nuclear Plant” one finds brazen legalese statements by the US NRC in order to defend one of Entergy’s aging reactors, Palisades (Note that the NRC also had lawyer(s) working on the corporate side pushing the judge to ignore current concerns at Davis Besse Nuclear Power Station too. Davis Besse and Palisades endanger the largest surface fresh water system on earth.) The NRC inadvertently points out that, most likely, no US nuclear reactor has the more resistant materials required for safety starting in 1977.

Someone asked the NRC:
“Which are the other most embrittled plants in the U.S.? How many PWRs will reach their screening criteria in the next 10 years?”
The NRC responded:
“The NRC currently estimates that the following plants will exceed the PTS screening criteria of 10 CFR 50.61 during their 20-year period of operation beyond their original 40 year licenses. Updated fluence calculations, capacity factors changes, power uprate, new surveillance data, and improved material property information (i.e., the use of direct rather than correlative measurements of the vessel material’s resistance to fracture) can change these estimates…
1. Point Beach 2 (2017)
2. Palisades (2017)
3. Diablo Canyon 1 (2033)
4. Indian Point 3 (2025)
5. Beaver Valley 1 (2033)”

(It’s not clear if these years are the license expiration dates, or when they are estimated as in most danger of reactor pressure vessel fractures, minus uprates etc, which increase stress and put them at risk more quickly. PTS is Pressurized Thermal Shock. Point Beach is also on the Great Lakes (Lake Michigan, as is Palisades)

According to the NRC, Entergy-Palisades didn’t violate standards because there weren’t any! “Palisades did not violate the NRC’s PTS safety standards in 1981 since the NRC did not have any regulations pertaining to PTS until June 26, 1984.”

The NRC inadvertently explains that US Reactors are not up to even 1977 standards:
“For new plants, the reactor vessel beltline materials should have the content of residual elements such as copper, phosphorus, sulfur, and vanadium controlled to low levels. The levels should be such that the predicted adjusted reference temperature at the ¼ T position in the vessel wall at end of life is less than 200 °F. [These] recommendations … will be issued in evaluating construction permits docketed on or after June 1, 1977.”http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf

“There has been no ground-breaking on new nuclear plants in the United States since 1974. Up until 2013, there had also been no ground-breaking on new nuclear reactors at existing power plants since 1977.”http://en.wikipedia.org/wiki/Nuclear_power_in_the_United_States
Since permitting would normally come before ground-breaking this appears to mean that no nuclear reactors currently in operation are up to the 1977 standards for prevention of embrittlement. 1977 was 37-38 years ago. Jimmy Carter was President and the Cold War was far from over. Apple home computers weighed 11.5 pounds excluding the screen, which probably weighed almost as much. Apple Ipad air weighs less than one pound.

The NRC further states:
“In conclusion, there was no violation of NRC requirements concerning PTS at Palisades. Had Palisades ever violated PTS requirements the NRC would have shut down the plant.

Regulatory Guides do not contain requirements, only recommendations.”http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf

So, since the “Regulatory Guides only contain recommendations”, anything goes? What’s the NRC for then? Making the US tax-payer pay for lawyers and staff to protect the interests of the nuclear power industry? Safety doesn’t matter? Regulations are supposed to be laws. Aren’t they?

Where did concern about the US budget go anyway? A good place to start cuts is the US NRC, which has long been called an instance of regulatory capture. ……..https://miningawareness.wordpress.com/2015/04/09/us-nrc-playing-brazen-legalese-games-with-safety-reactor-pressure-vessel-embrittlement-at-palisades-nuclear-power-station-and-elsewhere/
