NRC & NEAC Meeting Concerning Millstone Station Performance Reactor Oversight Program - CY 2005 Nuclear Regulatory Commission - Region I King of Prussia, Pennsylvania March 29, 2006

Purpose of Todays Meeting A public forum for discussion of Millstone Stations annual performance for CY 2005 NRC will address Millstone Stations performance as discussed in the NRC annual assessment letter to Dominion Nuclear Connecticut, Inc.

NEAC will be given the opportunity to respond to the information, request clarifications, and ask additional questions as needed

NRC Performance Goals z Safety: Ensure protection of the public health and safety and the environment z Security: Ensure the secure use and management of radioactive materials z Openness: Ensure openness in our regulatory process z Effectiveness: Ensure that NRC actions are effective, efficient, realistic, and timely z Management: Ensure excellence in agency management to carry out the NRC strategic objective

Reactor Oversight Process Strategic Performance Areas Safety Cornerstones Baseline Inspection Performance Indicator Results Results Significance Significance Threshold Threshold Action Matrix Regulatory Response

Examples of Baseline Inspections z Equipment Alignment ~80 hrs/yr z Triennial Fire Protection ~200 hrs every 3 yrs z Operator Response ~125 hrs/yr z Emergency Preparedness ~80 hrs/yr z Rad Release Controls ~110 hrs every 2 yrs z Worker Radiation Protection ~90 hrs/yr z Corrective Action Program ~250 hrs every 2 yrs z Corrective Action Case Reviews ~60 hrs/yr

Significance Threshold Performance Indicators Green: Baseline Inspection White: May increase NRC oversight Yellow: Requires more NRC oversight Red: Requires more NRC oversight Inspection Findings Green: Very low safety issue White: Low to moderate safety issue Yellow: Substantial safety issue Red: High safety issue

Action Matrix Concept Licensee Regulatory Degraded Multiple/Rep. Unacceptable Response Response Cornerstone Degraded Performance Cornerstone Increasing Safety Significance Increasing NRC Inspection Efforts Increasing NRC/Licensee Management Involvement Increasing Regulatory Actions

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
