1.0 INTRODUCTION

l By letter dated December 16, 1988, OmahaPub11cPowerDistrict(OPPD)-

subnitted an appMeation for an amendment to Facility Operating t Ronst-No. DPR-40 that would modify the fort Calhoun Statiom, Unit No.1, Technical Specifications to (1) increase the minimum allowablt Safety Injection and '

Mueling Water Tank (SIRWT) temperature.fecm c0*F to 50 F, (2) change I the titia of the Senior Vice President - A'uclear Operations', Production Operations, Production Engineering, and Cus11ty and Environmer,tal Aff airs to Senior Vice President - Nuclear Operations, Production Engimeririg, and Quality and Environmental Affair % (3) administratively correct the listed- s hRC address to which the Monthly Operating Peprarts are sent, and (4) co two referencer to the Updated Shfety Analysis Report in TS 3.5(89)b.(1)rrect '

and 2.1.3. Additionally, the amendment would revise facility Operating i' License DPRe4U te delete present paragraph 3.0, relateil to a inodificction te the Spent Fuel Pool, since it is no longer applicable.

20 f!SOUSSION 2.1 Safety Injection anJ Refueling Water Tank Temperature The licensee has determined that the thermal transient testing conducitL4  !

on the low pressure safety infection (LFSI) pumps and the containment i ,

spray (C5) pumps was conducted with an actuel inlet water temperature trousient of 50 F to 303 F and 308'F to 45'r. The Fresent TS 2.3, l Emergency Core _ Cccling System, requires the fluid contents of thi SIRWT, which supplies the inlet water to both the LPSI ar.d CS pumps, to be at a ,

temperature of not less than 40'F. Therefore: it is possible that ths );

i;nlet water could be in the runge kelow that for which the performance of these pum;s have been verified. The prope ed chcnge to TS 2.3 will restrict j the allowa ble operating range to remain witt'n that of the pump qualification j and will e nsure that the pumps will function as required during a design j basis acc' dent conditiot Since the range of allowed SIRWY fluld temperature j will remain within the range utilized 4 the analyzed accidents and transieni.$, j no further analysis was necess6ry Thus, the staff finds that the proposed change to SIRWT minimum teraperature is acceptable.

Specifications to be in effect when the new storage racks wer.e instaTied.

The modification was completed in 1983 and the specific Technical Specifica- /

This ch3nge in title reflects a recent feergu.htico which new assigns the Senior Vice Preside 6t responsibility tver only nuclear activities. The Producticr.

Since this change dee:s not alter in any way the respcnsibilit M cr activities stated in the Technical Specifications, the staff finds that the prop 0Sec change to be acceptable. j
