Niagara Mohawk Power Corporation hereby transmits an Application for amendment to Nine Mile Point Unit 2 Operating License NPF-

69. Also enclosed are the proposed changes to the Technical Specifications set forth in Appendix A of the above mentioned license. Supporting information and a. tyaes demonstrating'that the proposed changen involve.no significant hazards considerations pursuont to 10 CFR 50.92 are included as Attachment B.

The proposed- Technical Specificatica chat.;?s cm.t ined herein represent revisions to Section 3.7.7.10, w .soactive Gaseous Effluent Monitvring Inst.rumentation." Specifically, Table 4.3.7.10-1, " Radioactive Gascous Effluent Monitoring Instrumentation Surveillance Requirements," is.being proposed for revision to require isolation of the offgas system as part of the ,

28 month channel calibration for the Noble Gas Activity Monitor.

Tr.is is in lieu of the requirement to demonstrate actual isolation during the monthly functional test. Isolation of the offgas system during plant operation can result in loss of vacuum and a resultant turbine trip. Table 3.3.7.10-1, " Radioactive Gaseous Effluent Monitoring Instrumentation," is also being

! proposed for revision to reflect the as-built configuration of the Noble Gas Activity Monitor instrumentation.

, Pursuant to 10CFR50.91(b)-(l), Niagara Mohawk has provided a copy of this license amendment request and'the associated Lnalysis regarding no significant hazards to the appropriate state representative.

Very truly yours, NIAGARA MOHAWK POWER. CORPORATION B. R('hylvia Executive Vice President - Nucleat 000449GG1 b O '
