SUBJECT:
Comments on Proposed Rule 10 CFR Part 50, RIN 31 50-AH29, Risk-Informed Changes to Loss-of-Coolant-Accident Technical Requirements (70 Federal Register 67598, November 7, 2005)
Virginia Electric and Power Company (Dominion),
Dominion Nuclear Connecticut, Inc. (DNC), and Dominion Energy Kewaunee, Inc. (DEK) appreciate the opportunity to comment on the subject proposed rule.
We commend the NRC for moving to the proposed rule stage of this important effort that proposes a voluntary alternative to the existing 10 CFR 50.46 rule.
This voluntary alternative establishes a more realistic yet still conservative design basis break size for analyzing the performance of Emergency Core Cooling Systems (ECCS) during loss of coolant accidents (LOCA).
While Dominion fully supports the concept of redefining the large break LOCA embodied in this rulemaking, the rule as currently proposed is excessively burdensome, particularly in the areas of operational restrictions and the risk-informed integrated safety performance assessment process.
As currently proposed, Dominion would not implement this voluntary alternative to the existing 10 CFR 50.46 rule.
Dominion fully endorses the detailed comments provided by the Westinghouse Owners Group and the Nuclear Energy Institute on this proposed rulemaking.
The viability of this voluntary alternative to the existing 10 CFR 50.46 rule will be contingent upon how these comments are addressed.
