Operating Reactors Branch #2 Division of Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Ragulatory Commission Washington, D. C. 20555 License No. OPR-35 Docket No. 50-293 Revised Technical Specifications For PNPS Reload 5

References:

(a) BECo Letter #81-222, " Reload 4 Submittal and Request for Technical Specification Changes", dated September 22, 1981 (b) BECo Letter #81-237, " Corrected Page for Reload 5 Submittal", dated October 5,1981 (c) BEco Letter #81-256, "PNPS Core Spray Sparger Inspection Results", dated November 17, 1981

Dear Sir:

Reference (a) contained Technical Specification changes proposing a continuance of the current reduced MAPLHGR limits which assume no credit for core spray heat trans fer. These reduced limits were established as a conservatism because of'the core spray distribution uncertainties brought about by the 1980 sparger inspections.

However, the concerns about sparger performance have been eliminated as a result of the more thorough inspection performed during the current refueling outage.

These inspection results were reported in Reference (c).

Therefore, in order to remove this reduction in operat.ing limits we request that you replace the Tcchnical Specif.ication change pages submitted via References (a) and (b) in their entirety with the attached. The analyses which accompanied Reference (a) remain in applicability to the Reload Submitt A. Please note that the change in MAPLGHR will not significantly affect the actel plant operation in Cycle 6 since the core, which has been designed for this cycle, will also operate within the "no core spray credit" limits. The changes will, however, increase operating margin which will be necessary for the implementation at or near the beginning of Cycle 6 of the spectral shift operating mode or other presently.
