SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 126 TO FACILITY OPERATING LICENSE NO. NPF-47 ENTERGY OPERATIONS, INC.

RIVER BEND STATION, UNIT 1 DOCKET NO. 50-458

1.0 INTRODUCTION

By application dated July 10, 2002, Entergy Operations, Inc. (Entergy or the licensee) requested changes to the Technical Specifications (TSs) (Appendix A to Facility Operating License No. NPF-47) for the River Bend Station, Unit 1 (RBS). The proposed changes would revise the TSs to extend the testing interval for the control rods from 120 days cumulative operation in Mode 1 to 200 days cumulative operation in Mode 1.

2.0 BACKGROUND

The TS governing the control rod scram time surveillance are intended to assure proper function of control rod insertion. Following each refueling outage, all control rod scram times are verified. In addition, periodically during power operation, randomly selected control rods are to be partially inserted to verify the insertion speed. The TS stipulates that no more than 10 percent of the control rods can be slow during the post outage testing. The licensee has set the acceptance criterion for at-power surveillance at 7.5 percent of the total control rods exceeding the scram time specified limit.

3.0 EVALUATION Over the course of the operating life of RBS, the control rod insertion time test results have shown the control rod scram rates to be highly reliable. During 15 years of operation, out of 3,893 control rod insertion tests, only two control rods have been slower than the insertion time limit. In addition, there have been no inoperable control rods. The extensive historical database substantiates the claim of high reliability of the RBS control rod drive system. The current TS requires that 10 percent of the 145 control rods, or 15 rods, be tested via random sampling every 120 cumulative days of operation in Mode 1. Entergy has requested extension of the surveillance interval to 200 cumulative days of operation in Mode 1.

The current TS states that the acceptance criteria have been met if 20 percent or fewer of the random sample control rods that are tested are found to be slow. Entergy has proposed that the slow insertion time control rod acceptance criteria be reduced to 7.5 percent of the random sample when the surveillance period is extended to 200 cumulative days of operation in Mode 1.

The staff considers the extended surveillance interval to be justified by the demonstrated reliability of the RBS control rod insertion system, based on historical control rod scram time test data, and by the more restrictive acceptance criterion for the number of slow rods allowed during at-power surveillance testing. The staff finds the proposed TS change to be acceptable.

4.0 STATE CONSULTATION

In accordance with the U.S. Nuclear Regulatory Commissions (NRC or the Commission) regulations, the Louisiana State official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (67 FR 58641, published September 17, 2002). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
