REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED AMENDMENT TO TECHNICAL SPECIFICATIONS SELECTIVE IMPLEMENTATION OF THE ALTERNATIVE SOURCE TERM FUEL HANDLING ACCIDENT ANALYSES MILLSTONE POWER STATION, UNIT NO. 2 DOCKET NO 50-336 By letter dated September 26, 2002, Dominion Nuclear Connecticut, Inc. (the licensee) submitted a proposed amendment to the Technical Specifications (TSs) for Millstone Power Station, Unit No. 2 (MP2). The proposed amendment would revise the TSs based on a re-analysis of the limiting design basis Fuel Handling Accident (FHA) using an Alternative Source Term in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Section 50.67 and Regulatory Guide 1.183.

The Nuclear Regulatory Commission (NRC) staff has reviewed the information the licensee provided that supports the proposed TS changes. In order for the staff to complete its evaluation, the following additional information is requested:

The proposed changes to TS 3.9.4, Containment Penetrations, would require that any containment penetration that provides direct access to the outside atmosphere, including the equipment hatch and personnel airlock doors, be capable of being closed under administrative controls within 30 minutes of an FHA. The proposed Bases for TS 3.9.4 and Attachment 2, page 8, of the licensee's submittal state that if it is determined that closure of all containment penetrations would represent a significant radiological hazard to the personnel involved, the decision may be made to forgo the closure of the affected penetration(s). Clarify what is meant by significant radiological hazard and describe the specific criteria that will be incorporated into the administrative controls to determine whether to forgo closure of the affected penetration(s).
