SUBJECT:
CHANGE TO TECHNICAL SPECIFICATION BASIS SECTION 4.8 REGARDING TESTING OF THE STEAM DRIVEN AUXILIARY FEEDWATER PUMP FOR THE H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 (TAC NO. M93571)
Dear Mr. Hinnant:
By letter dated June 1, 1995, Carolina Power & Light Company (CP&L) proposed a change to the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBR), Technical Specifications (TS) Basis section 4.8. The Basis change clarifies stable conditions for the surveillance testing of the steam driven auxiliary feedwater pump after a period in which the reactor has been in cold shutdown.
The NRC staff has reviewed the proposed basis change regarding stable plant conditions for conducting surveillance tests on the steam driven auxiliary feedwater pump and has no objection to your proposed change.
Enclosed is a copy of the revised Basis page.
Sincerely, (Original Signed By)

4.8.5 The survd ance requirements for auxilia feedwater system automatic initiation shall be as stated in Table 4.8-1.
Basis The monthly testing of the auxiliary feedwater pumps by recirculation will verify their operability. The capacity of any one of three auxiliary
(,edwater pumps is sufficient to meet decay heat removal requirements,
Proper functioning of the steam turbine admission valve and the starting of the feedwater pumps will demonstrate the integrity of the steam driven pump.
Verification of correct operation will be made both from instrumentation within the control room and direct visual observation of the pumps. Testing of the steam turbine auxiliary feedwater pump is not required during periods of cold shutdown when steam is not available. In this condition the pump is not required for plant safety. If the steam turbine driven auxiliary feedwater pump has exceeded its surveillance interval following a period of reactor cold shutdown, then the surveillance test shall be performed prior to reactor criticality, but not to exceed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the reactor coolant system has been at a minimum 547 deg. F.
