SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 87 TO FACILITY OPERATING LICENSE NO. NPF-42 WOLF CREEK NUCLEAR OPERATING CORPORATION WOLF CREEK GENERATING STATION DOCKET NO. 50-482
1.0 INTRODUCTION
By application dated March 24, 1995, Wolf Creek Nuclear Operating Corporation (the licensee) requested changes to the Technical Specifications (TS)
(Appendix A to Facility Operating License No. NPF-42) for the Wolf Creek Generating Station.
One of the proposed changes would revise Surveillance Requirement 4.5.1.1.b to relax accumulator sample requirements after refilling provided the makeup source is from the refueling water storage tank (RWST).
2.0 SACKGROUND Surveillance Requirement 4.5.1.1.b currently requires the accumulator to be sampled and boron concentration determined every 31 days and within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after a solution volume increase of greater than or equal to 70 gallons.
In NUREG-1306, " Improvements to Technical Specifications Surveillance Requirements", Section 7.1, " Surveillance of Boron Concentration in the Accumulator / Safety Injection Tank / Core Flood Tank (PWR)", the staff recommended that boron concentration verification of the accumulator after a volume increase be relaxed provided (1) the makeup is from the RWST and the boron concentration in the RWST is greater than or equal to the minimum required concentration in the accumulator, (2) the most recent RWST sample was within specifications, and (3) the RWST has not been diluted.
Generic Letter 93-05, "Line-Item Technical Specifications Improvements to Reduce Surveillance Requirements for Testing During Power Operation," dated September 27, 1993, provided guidance to licensees in preparing amendment requests based on the NUREG-1306 recommendations.
3.0 EVALUATION The licensee has proposed to change Surveillance Requirement 4.5.1.1.b by adding the following sentence:
"This surveillance is not required when the volume increase makeup source is the RWST and the RWST has not been diluted since verifying that its boron concentration is within limits of Specification 3.5.5."
9506090425 950530 PDR ADOCK 05000482 P
. TS 3.5.5 is the limiting condition for operation (LCO) for the RWST.
This section requires the RWST to be maintained at a boron concentration of between 2400 and 2500 ppm of boron.
TS 3.5.1 is the LC0 for the accumulator.
This section requires the accumulator boron concentration to be maintained between 2300 and 2500 ppm. This change meets the staff's position for relaxing the requirement to sample the accumulator after a volume increase provided the makeup source is the RWST. The staff fiads this change acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Kansas 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 surveillance requirement.
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 (60 FR 18632).
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, 1
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 Commission's 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.
