SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMEN 0 MENT NO. 5 TO FACILITY OPERATING LICENSE NO. NPF-47 GULF STATES UTILITIES COMPANY 3
RIVER BENO STATION, UNIT 1 DOCKET NO. 50-458 i
1.0 INTRODUCTION
By letter dated August 4, 1986 as supplemented by. letters dated August 15 and September 26, 1986, Gulf States Utilities Company (GSU) (the licensee) requested an amendment to Facility Operating License No. NPF-47 for the River Bend Station, Unit 1.
As discussed in the River Bend SSER No. 3, Item 7 to the River Bend Operating License was imposed to ensure that River Bend Station will continue to meet GDC 17 beyond the first refueling outage.
Specifically, this license condition requires " Operation beyond the first refueling outage is subject to NRC staff approval based on the staff's final review of the Owners Group generic findings and of the overall design review and quality revalidation program at River Bend."
In June 1986, the NRC staff's generic Safety Evaluation Report (SER) on the operability / reliability of Emergency Diesel Generators (EDG's) manu-l factured by Transamerica Delaval, Inc. (TDI) was transmitted to GSU.
The staff concluded that compliance with the recommendations contained in the generic SER (NUREG-1216) would provide an acceptable, technical resolution of the concerns regarding the performance of TDI EDGs for service at nuclear plants.
The staff requested GSU to provide its plans for implemen-tation of the programs identified in the generic staff SER for_ River Bend, Unit 1. Therefore, by responding acceptably to the staff SER, the licensee would comply with the license condition.
As described in the staff's generic SER, the TDI Owners Group Program Plan consisted of the following major elements:
(1) Phase I:
Resolution of 16 known generic problem areas intended by the Owners Group to serve as an interim basis for the licensing of plants; 4
(2) Phase II:
A design review / quality revalidation (DR/QR) of a large set of important engine components to assure that their design and i
manufacture are adequate; and (3) Expanded engine tests and inspections to support Phase I and II.
2.0 EVALUATION By letters dated August 4, August 15 and September 26, 1986, GSU had out-lined its plans for implementation of the problems identified in the 8706110418 870604 S i
PDR ADOCK 05000458=
p PDR;
- staff's generic SER for resolving the TDI reliability issue.
Specifi-cally, GSU plans to implement Phase I ar4 II as discussed in the generic.
SER and the maintenance and surveillance recommendations developed by the Owners Group in Appendix II, Revision 2, of the DR/QR report for RBS; and future TDI recommendations would be evaluated by GSU and would be imple-mented as appropriate.
The staff has required that any future revisions to the maintenance /sur-veillance program would be subject to.the provisions of 10 CFR 50.59 in view of the importance of this program in ensuring the operability / relia-bility of the engines over the long term.
Furthermore, as described in the staff's generic SER, there are certain components that warrant special emphasis in terms of maintenance / surveillance actions to assure their adequate. service.
The staff. requested GSU to submit these maintenance /
surveillance actions in the form of. proposed license conditions as speci-fied by the generic SER.
Accordingly, by letter dated August 4, 1986, the licensee has proposed a' revision to Attachment 3 of the River Bend operating-license as well as a revision to Technical Specification 4.8.1.1.2.f.1.
This revision to the' technical specifications would change the required inspection interval for the TDI EDG's from once every 18 months to once every refueling outage, which conforms to the interval recommended by the TDI Owners Group.
i l
By letter dated April 1, 1987, the staff informed the licensee of clarifi-cations to the generic SER contained in NUREG-1216.
In telephone conver-1 sations with the licensee on May 11 and 12, 1987, documented by letter dated May 21, 1987, the staff identified deficiencies in the licensee's l
proposed revisions to Attachment 3 of its operating license.
The staff i
will continue its review on Attachment 3 pending revision to the proposed i
amendment by the licensee.
In its request of August 4, 1986 as amended on August 15, 1986, the licensee proposed amending Technical Specification 3/4.8.1.1.2.f.1 to require inspection of the River Bend TDI EDG's every refueling outage in-accordance with procedures prepared in conjunction with the manufacturer's recommendation. The current Technical Specifications require inspection every 18 months.
The staff finds the licensee proposal acceptable in this area as it is consistent with the generic SER (NUREG-1216).
3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a change to a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase in the amounts, and no signifi-cant 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 this amendment involves no significant hazards consideration and there has been no public comment on such finding.
Accordingly, this amendment meets the eligibility criteria for categorical
d b=
- exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b),
no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
The staff 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, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and the security nor to the health and safety of the public.
