END OF THE PRESENTATION Nuclear Regulatory Commission - Region I King of Prussia, Pennsylvania March 29, 2006

Potential Public Interest Issues Safety Concerns Brought to the NRC z NRC has a formal process z Concerns are reviewed on an individual basis by NRC technical, legal, investigative staff and management z Issues of immediate concern receive prompt attention by NRC and by nuclear power plant management z NRCs process requires reviews of all valid safety issues to ensure they are adequately addressed z NRC implements measures to protect the identity of allegers including not commenting on the existence of a specific allegation

Potential Public Interest Issues Recent Press Articles on Security Issues z Current NRC policy is to not discuss security matters in a public forum z NRC will not comment on existence of allegations in this area z Notwithstanding these policies, we want to assure the public that if safety issues did exist, the NRC would take prompt action to address them

Potential Public Interest Issues Strontium-90 (SR-90) z Fission process byproduct (29 year half-life) z Potential sources in the Environment

- 16,800,000 curies - nuclear weapons testing (UNSCEAR 2001)

- 212,000 curies - 1986 Chernobyl accident (UNSCEAR 2001)

- 0.00012 to 0.001 curies - from all 103 operating nuclear power plants z For nuclear reactor releases, SR-89 (50 day half-life) is always present with SR-90

Potential Public Interest Issues Strontium-90 (SR-90) continued z Mid 1990s - Release levels of SR-90 were so low that nuclear utilities had difficulty measuring the amounts released z NRC allowed SR-90 monitoring by using goat milk samples z Goat milk samples indicated low levels of SR-90 without the presence of SR-89 (indicating not originating from a nuclear power plant) z Most likely source is from 1950s and 1960s atmospheric nuclear weapons testing

Potential Public Interest Issues Radiation Exposure to the Public from Background Sources and from Millstone Power Station z Natural
