Docket No. 50-285 Mr. Terry. L. Patterson Division Manager - Nuclear Operations Omaha Public Power District Fort Calhoun Station FC-2-4 Adm.

Post Office Box 399 Hwy. 75 - North of Fort Calhoun Fort Calhoun, Nebraska 68023-0399

Dear Mr. Patterson:

SUBJECT:

EVALUATION OF INSERVICE TESTING PROGRAM RELIEF REQUEST FOR SAFETY INJECTION TANK CHECK VALVES - FORT CALHOUN STATION (TAC NO. M84503)

The enclosed safety evaluation (SE) provides the result of the NRC review of l

information relating to valve relief request E4 in the Fort Calhoun Station third 10-year pump and valve inservice testing (IST) program.

This information was provided by Omaha Public Power District (the licensee) in letters dated September 3 and November 13, 1992, as supplemented by letters dated June 11 and July 13, 1993. The SE for other relief requests submitted i

for the third 10-year interval will be provided at a later date.

Relief request E4, which concerns stroke testing of safety injection tank (SIT) check valves, is an updated version of relief request E19 for the second 10-year interval ending September 15, 1993. The NRC SE dated March 26, 1992, granted relief for E19 on an interim basis pending completion of staff's detailed evaluation of the licensee's valve exercising methodology. The enclosed SE for E4 completes this detailed evaluation and the review of E19.

The NRC, with technical assistance from Oak Ridge National Laboratory (ORNL),

i has reviewed the information provided by the licensee for E4. As explained in i

the enclosed SE, the staff adopts the analysis and conclusions contained in the enclosed report, ORNL/NRC/LTR-93/16, " Analysis of Proposed Testing of Safety Injection Tank Discharge Check Valves Using a Flow Resistance Methodology," prepared by ORNL.

Based on the determination that the alternative testing is consistent with OM-10, Paragraph 4.3.2.2 requirements, the staff finds that no relief is required provided the licensee documents the justification for deferral of stroke testing in accordance with OM-10, Paragraph 6.2(d), and follows the recommendations specified in the enclosed
