Acceptance Review: MPS2 Relief Request RR-04-02

Dear Mr. Bartron:

By letter dated March 30, 2010, Dominion Nuclear Connecticut, Inc. (DNC) submitted relief request RR-04-02 for Millstone Power Station, Unit No. 2 (MPS2). The proposed relief request would allow the pressure test of the lower portion of the Reactor Pressure Vessel to occur at different plant conditions than those required by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. Specifically, DNC proposes to conduct the test during refueling outages instead of at the required pressure, which is a pressure not less than the pressure corresponding to 100% rated reactor power. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this relief request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review.

The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. You will be advised of any further information needed to support the NRC staff's detailed technical review by separate correspondence.

If you have any questions, please contact me at (301) 415?1603.

Sincerely, Carleen Sanders, Project Manager Plant Licensing Branch I-2
