D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 85 TO FACILITY OPERATING LICENSE NO. DPR-38 AMENDMENT NO.85 TO FACILITY OPERATING LICENSE NO. DPR-47 AMENDMENT NO.82 TO FACILITY OPERATING LICENSE NO. DPR-55 DUKE POWER COMPANY OCONEE NUCLEAR STATION, UNITS NOS. 1, 2 AND 3 DOCKETS NOS. 50-269, 50-270 AND 50-287 Introduction By letter dated July 31, 1980, the Duke Power Company (licensee) requested a temporary Technical Specification (TS) change for the Oconee Nuclear Station, Unit.No. 2 (Oconee-2). The proposed change would revise TS 3.3.1, High Pressure Injection (HPI) System, Section c.(2)(b).
Background
HPI pump 2B failed on July 26, 1980; on July 29, 1980, a replacement pump also failed; the licensee reduced power to 60% as required by TS 3.3.1.
The failure of the first pump is due to the impeller shifting on the pump shaft and binding on the pump casing. The pump manufacturer, Ingersoll-Rand, has two service representatives at Oconee who are working to both determine cause of failure of the second pump and to attempt repairs of one of the failed pumps. Due to the severe hot weather in the Oconee service area and the marginal ability of the electrical utilities in the area to meet their power demands, the licensee requested this temporary change to permit 100% power operation of Unit 2, on a conditional basis, through August 15, 1980. Pump repairs or replacement will not be complete before that date.
Evaluation Of the remaining two HPI pumps, the "A" pump is in operation for system make-up and reactor coolant pump seal injection flow. The "C" pump is in standby; this, pump was verified operable on July 17, 1980. The licensee stated all power supplies, instrumentation and controls, and auxiliary support systems for the HPI system are operable.
Three HPI pumps are required to be operable only in the event of (1) a limiting single failure in the HPI system, and (2) a postulated break in the primary cold leg piping of between 0.04 and 0.10 sq. ft. in the vicinity of the HPI nozzle for which the HPI flow is assumed lost and failure of one of the HPI pumps.

3.3.1.c.(2)(c)T (Temporary Technical Specification)
For Oconee 2, HPI pump B, the requirements of Specification 3.3.1.c.(2)(b) are amended as follows:
Conditions where upon Oconee Unit 2 may be escalated to 100% FP in order to meet expected peak demand.
- 1. All Duke system generation capability has been utilized to the maximum extent available.
- 2. All available purchases from other VACAR utilities have-been utilized.
- 3. All available purchases from outside the VACAR subregion have been utilized.
If all of the above conditions are satisfied and the total available generation capacity is not expected to be sufficient to meet the expected peak load and the required spinning reserves, then Oconee 2 will be escalated in power up to 100% FP.
This Temporary Technical Specification will expire at 11:59 p.m. on August 15, 1980.
