NIAGARA MOHAWK POWER CORPORATION ) Docket No. 50-410

)

Nine Mile Point Nuclear Station Unit 2 )

APPLICATION FOR AMENDMENT TO OPERATING LICENSE Pursuant to Section 50.90 of the Regulations of the Nuclear Regulatory Commission, Niagara Mohawk Power Corporation (NMPC), holder of Facility Operating License No. NPF-69, hereby requests that Section 3.3.2 of the Technical Specifications (TS) set forth in Appendix A to that License be amended. The proposed changes have been reviewed in accordance with Section 6.5 of the TS.

The proposed changes to the TS are set forth in Attachment A to the Application. NMPC proposes to revise TS Section 3/4.3.2, " Isolation Actuation Instrumentation." The proposed revision will establish a range of allowable and trip setpoints for High Temperature in the Main Steam Line Tunnel Lead Enclosure. NMPC has determined that the current TS requirements could result in unnecessary challenges to the plant and its safety systems depending on environmental conditions. The current requisements were established based on the most conservative environmental parameters (winter conditions). NMPC has determined that basing the requirements on actual environmental conditions does not have a significant adverse effect on : afety, and reduces the potential for unnecessary safety system challenges.

The proposed changes would not authorize any change in the types of effluents or in the authorized power level of the facility. Supporting information and analyses which demonstrate that the proposed changes involve no significant hazards considerations pursuant to 10CFR50.92, are included as Attachment C.

WHEREFORE, Applicant respectfully requests that Appendix A to Facility Operating License No. NPF-69 be amended in the forms attached hereto as Attachment A.
