DOCKETS 50-266 AND 50-301 MODIFICATION TO THE BASIS SECTION FOR TECHNICAL SPECIFICATION 15.3.3

" EMERGENCY CORE COOLING SYSTEM, AUXILIARY COOLING SYSTEMS, AIR RECIRCULATION FAN COOLERS. AND CONTAINMENT SPRAY" POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 On September 12, 1994 we submitted Technical Specifications Change

~

Request (TSCR) 169, " Emergency Core Cooling System,-Auxiliary Cooling Systers, Air Recirculation Fan Coolers, and Containment Spray," for Point Beach Nuclear Power Plant (PBNP) Units 1 and 2.

The proposed changes modified Technical Specification 15.3.3, l

" Emergency Core Cooling System, Auxiliary Cooling Systems, Air j Recirculation Fan Coolers, and Containment Spray," to incorporate <

allowed outage times similar to those contained in NUREG 1431, Revision 0, " Westinghouse Owner's Grouc Improved Standard Technical Specifications," and clarify the operability requirements for the service water pumps. Proposed changes were also included to clarify the completion times for placing a unit in hot or cold shutdown if a limiting condition for operation cannot be met.

Our proposed change to Technical Specification (TS) 15.3.3.A.3 required that the reactor be placed in hot shutdown within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and reactor coolant system temperatures be maintained between 500*F and 350*F if residual heat removal (RHR) components are l not returned to service within the required time period. On l November 16, 1994, we' submitted an addendum to TSCR 169 to, in

, part, change this requirement to state that reactor coolant system (RCS) temperatures shall be maintained greater than 350*F after placing the reactor in the hot shutdown condition. However, we inadvertently did not propose corresponding changes to the Basis for TS Section 15.3.3 in our November 16, 1994, letter.

. . l Document control Desk February 1, 1995 Page 2 License Amendments 159/163 were issued on December 21, 1994, to approve TSCR 169 as modified by our November 16, 1994, addendum.

This resulted in the Basis for TS Section 15.3.3 referring to maintaining RCS temperatures between 500*F and 350'F which is inconsistent with the revised Specification. We have changed 4

the Basis section to be consistent witn the modification to TS 15.3.3.A.3 under the 10CFR50.59 safety evaluation process.

A copy of the affected page, with the revised text indicated by a margin bar, is enclosed.
