NRC’s Jaczko Responds to Rep. Markey on the Sr-90 Issue at Vermont Yankee

It’s been a few weeks since I posted about Entergy responding to Rep. Edward Markey (D-Mass.) on the strontium-90 (Sr-90) issue at the Vermont Yankee nuclear plant . NRC Chairman Gregory Jaczko has since weighed in, on the NRC’s behalf, with a letter he sent to the congressman. Of note, the chairman’s letter echoes what Entergy officials and the Vermont Department of Health (VTDH) have been saying all along: Because there are multiple potential sources of Sr-90, including nuclear weapons testing by multiple countries in the middle of the last century, it is very difficult to draw conclusions about the source of any particular Sr-90 contamination that is found in the environment unless there is additional supporting evidence. Because of this fact, Jaczko believes that Entergy’s Laurence Smith, manager of communications, is fair in one of his statements that “There is absolutely no evidence to suggest that Vermont Yankee is the source for the strontium-90.” He writes: ...

Entergy Responds to Rep. Markey on Sr-90 Found in Fish

Two weeks ago, I blogged about Rep. Ed Markey (D-Mass.) accusing Entergy of not being truthful when it came to Strontium-90 (Sr-90) emissions from the Vermont Yankee nuclear plant . I just found out that Entergy’s Executive Vice President and Chief Administrative Officer Roderick West responded to Rep. Markey’s accusations in a letter to the congressman last week. Entergy’s overall position remains the same: While some may speculate as to the source of the Sr-90, the scientific evidence does not support any connection between the operations of Vermont Yankee and the June 2010 fish sample. In the letter, West quotes an Aug. 2 post written by Bill Irwin, radiological health chief at the Vermont Department of Health, who provides detailed information and data on the types of fish sampling conducted and compares that to previous research. However, without further evidence, Irwin says it is impossible to draw a clear conclusion that the Sr-90 that was found in the fish could be a res...

Entergy Rejects Reports SR-90 Found In Connecticut River Is From Vermont Yankee

Late on Friday afternoon, Rep. Ed Markey (D-Mass.) sent a letter to NRC Chairman Greg Jaczko accusing Entergy, the owner of the Vermont Yankee Nuclear Power Plant, of being less than truthful when it came to emissions of Strontium-90 (Sr-90) from the plant. The following comes from the Associated Press : Rep. Edward Markey, the top Democrat on the House Natural Resources Committee, wrote Friday to NRC Chairman Gregory Jaczko to complain that a spokesman for the Vermont Yankee nuclear plant had made statements “at odds with the factual history of the plant,’’ and that the “NRC had not appropriately responded to concerns raised about this issue.’’ Markey’s letter came nearly three months after the incident in question. On Aug. 2, the Vermont Health Department announced that the radioactive isotope strontium-90 had been found in the flesh of small-mouth bass caught in the Connecticut River about 9 miles upstream from the reactor in Vernon. The plant is about three miles from t...
