Speeches concerning Groundwater Contamination:
Agency Addresses Tritium Issue
Speech S-10-002, From NRC Reporter, Vol. 6, Issue 8, March 3, 2010
The agency is addressing the issue of tritium leakage in several ways.
Speaking at the sixth annual Platts Nuclear Energy Conference in Bethesda, Chairman Jackzo acknowledged that the conference is an important forum for discussion "the opportunities, challenges, and implications of the resurgence of interest in nuclear power," and the majority of his comments related to those issues. However, he pointed out, current concerns about leaking pipes and tritium highlight the fact that "NRC must always stay focused on ensuring that the existing fleet continues to operate in a safe, secure, and environmentally sensitive manner."
"That is our core mission, and I assure you that the agency has not lost sight of that," he said.
Chairman Jaczko said that tritium leakage takes on greater significance in the area of public perception: "People are asking legitimate questions – what's leaking, where's it leaking, how much is leaking, and – most importantly – what's being done to deal with the problem?"
The Chairman said that the agency always inspects licensees who have such leaks and in each case makes certain that the licensee is taking the appropriate steps to find the source and to protect the public and the environment. While that is being done, "We always have to ask ourselves at every turn whether we can we do more," he said. "That's why the agency is participating in a buried piping task force to evaluate the need for specific corrosion protection standards that could be implemented at nuclear power plant facilities."
A Road Less Traveled...a Road not Far...Soon, -Nils J. Diaz, Chairman
