SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NOS. 293 AND 230 TO FACILITY OPERATING LICENSE NOS. DPR-65 AND NPF-49 DOMINION NUCLEAR CONNECTICUT, INC.
MILLSTONE POWER STATION, UNIT NOS. 2 AND 3 DOCKET NOS. 50-336 AND 50-423
1.0 INTRODUCTION
By letter dated March 9, 2005, as supplemented by letter dated July 7, 2005, (Agencywide Documents Access and Management System (ADAMS) accession numbers ML050770238 and ML051920247, respectively) Dominion Nuclear Connecticut, Inc. (the licensee) submitted a request for changes to the Millstone Power Station, Unit Nos. 2 and 3 (MPS2 and MPS3)
Technical Specifications (TSs) to the Nuclear Regulatory Commission (NRC or the Commission). The proposed amendments make various changes to the TSs to incorporate wording related to the reactor coolant system, electrical power system and refueling operations to provide operational flexibility during mode changes or addition of coolant during shutdown operations. The proposed changes would limit the introduction of positive reactivity so that the TSs shutdown margin (SDM) and refueling boron concentration limits will be maintained.
Associated changes to the TS Bases are also included.
The supplement dated July 7, 2005, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the NRC staffs original proposed no significant hazards consideration determination as published in the Federal Register on May 24, 2005 (70 FR 29788).
2.0 REGULATORY EVALUATION
The proposed licensee changes adopt NRC-approved generic changes in the industrys Technical Specification Task Force Change Traveler (TSTF)-286, Revision 2, that were approved for incorporation into TSs by the NRC staff in a letter dated July 6, 2000. This TSTF revises the TS Required Actions that address suspension of operations involving positive reactivity additions, and also revises several limiting condition of operation (LCO) notes that address prevention of operations involving a reduction in reactor coolant system (RCS) boron concentration. The revisions limit the introduction into the RCS of reactivity that would be more positive than that necessary to meet the required SDM or refueling boron concentration, as applicable. TSTF-286 provides a model for licensees seeking to revise their plant TSs and, thus, clarify the limits on the introduction of reactivity such that the required SDM or refueling boron concentration will be satisfied.
The NRC staff has previously approved the type of changes addressed by TSTF-286 for other plants on a plant-specific basis. The previous approvals include, but are not limited to, H.B. Robinson, Unit 2, dated March 14, 2001 (ADAMS Accession No. ML010810282);
Callaway, Unit 1, dated May 1, 2002 (ADAMS Accession No. ML020220051); Wolf Creek,
dated July 29, 2002 (ADAMS Accession No. ML021290254); Catawba, Units 1 and 2, dated July 29, 2003 (ADAMS Accession No. ML032110122); and McGuire, Units 1 and 2, dated July 29, 2003 (ADAMS Accession No. ML032110073).
3.0 TECHNICAL EVALUATION
TSTF-286, Revision 2, approved the requested change in a generic manner, i.e., it is acceptable if the plant-specific conditions allow the implementation of the change. MPS2 is a Combustion Engineering (CE) plant, while MPS3 is a Westinghouse (W) plant. In the following evaluation, application of TSTF-286, Revision 2, will be examined for each Millstone unit.

4.0
SUMMARY
The NRC staff has reviewed the licensees application with the supporting documentation.
Based on its review, the NRC staff concludes that the proposed TS changes are acceptable because the proposed Notes and Required Actions limit the introduction into the RCS of coolant with a boron concentration that is less than that required to meet the required SDM or refueling boron concentration. These changes are consistent with the approved TSTF-286, Revision 2, taking into account the plant-specific design differences of MPS2 and MPS3. The justification for TSTF-286, Revision 2, is applicable to MPS2 and MPS3 and continues to ensure that the required minimum SDM and boron concentration to preclude inadvertent criticality are met. Since the licensees proposed amendments will still require the minimum SDM and boron concentration to be maintained, the NRC staff concludes that the proposed amendments are acceptable.
5.0 STATE CONSULTATION
In accordance with the Commissions regulations, the Connecticut State official was notified of the proposed issuance of the amendments. The State official had no comments.
6.0 ENVIRONMENTAL CONSIDERATION
The amendments change requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding (70 FR 29788). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.
7.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
