UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 2055&4001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.
78 TO FACILITY OPERATING LICENSE NO. NPF-69 I GARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT 2 DOCKET NO. 50-410
- 1. 0 INTRODUCTION By application dated July 12,
- 1996, Niagara Mohawk Power Company (the licensee) requested an amendment to Technical Specification 6.2.2.i for Nine Mile Point Nuclear Station, Unit 2 (NMP2).
The proposed amendment would revise the specification for the normal working hours of unit staff who perform safety-related functions from "a normal 8-hour day, 40-hour week" to "an 8 to 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> day, nominal 40-hour week."
The change, in effect, would enable the licensee to establish unit staff work schedules that average 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per week using shifts as long as 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
- 2. 0 EVALUATION The NRC staff has previously approved the use of 12-hour shifts at other U.S.
commercial nuclear power plants and has found no evidence of adverse effects on plant safety resulting from the use of such shifts.
All other existing provisions of NMP2 TS 6.2.2 (e.g.,
concerning consecutive hours of work,
- overtime, and breaks) remain unchanged.
Thus, the proposed change does not alter the intent of the existing specification with respect to the number of hours that should normally be worked per week and NMP2 TS 6.2.2 will continue to provide adequate assurance that routine heavy use of overtime will not be necessary to provide adequate shift coverage.
The NRC staff finds the proposed change to be consistent with Section 5.2.2.e of NUREG-1433, Rev.
1, "Standard Technical Specifications, General Electric
- Plants, BWR/4" which provides licensees the option of specifying either an 8-hour or a 12-hour shift.
Although the licensee has proposed to specify a
range
(."8 to 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> day") rather than a specific shift length, the NRC staff has no safety concern with the proposed specification that affords the licensee the flexibilityto establish shift lengths within the 8-hour to 12-hour range.
The proposed amendment is consistent with current licensing practices and operating experience.
The revised shift working hours remain within limits demonstrated acceptable by operating experience.
Accordingly, the NRC staff concludes that the proposed change to Nine Mile Point Unit 2 Technical Specification 6.2.2.i is acceptable.
