UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 S
F Y EVALUATION BY TH OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.
45 TO FACILITY OPERATING LICENSE NO. NPF-63 CAROLINA POWER
& L GHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT UNIT 1
DOCKET NO. 50-400
- 1. 0 INTRODUCTION By letter dated Hay 15,
- 1993, as supplemented February 17, 1994, Carolina Power 5 Light Company (CPSL or the licensee) submitted a request for a change to the Shearon Harris Nuclear Power Plant, Unit 1, (SHNPP) Operating License NPF-63 to remove License Condition 2.C.(8),
as defined in Attachment 1 to Operating License NPF-63.
Since a generic evaluation by the NRC will not be completed in time to support the licensee's upcoming refueling outage, the licensee modified the original amendment request on February 25, 1994, to request a one-time exemption from implementing the Transamerica
- Delaval, Inc. (TDI), diesel requirements specified in the Attachment 1 during Refueling Outage No.
5 and the subsequent Operating Cycle No. 6.
The requested change would allow a one-time exemption from the emergency diesel generator License Condition 2.C.(8).
The February 17,
- 1994, and February 25, 1994, letters provided information within the scope of the original application and did not change the initial proposed no significant hazards consideration determination.
The Transamerica Delaval, Inc. (TDI), Owners Group was formed in late 1983 following the crankshaft failure at the Shoreham Nuclear Plant of an Enterprise emergency diesel generator (EDG) manufactured by TDI.
The Owners Group developed a detailed program plan to provide for generic design review and quality revalidation (DR/gR) of Enterprise EDGs.
This plan was reviewed by the NRC and approved in its August 13, 1984, Safety Evaluation (SE).
Following the issuance of the SE, the licensees in the Owners'roup developed and implemented the. DR/gR requirements in response to, and in accordance
- with, the program plan.
The specific details of the DR/gR were submitted to the NRC for review and the results of this review were documented in NUREG-1216, "Safety Evaluation Report Related to the Operability and Reliability of Emergency Diesel Generators Manufactured by Transamerica Delaval, Inc.," dated August 1986.
NUREG-1216 outlines specific provisions that were incorporated as a License Condition in the SHNPP Operating License.
At the time of the DR/gR review, these conditions were imposed on SHNPP as well as other plants with Enterprise EDGs being licensed at the time because little operating history of these engines was available.
Since that time, the industry has accumulated over 9,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> of operational history for these 9403080223 F40303 i

engines.
The inspections required by plant license conditions have not revealed any significant problems from operation of the engines.
The analysis of the inspection results is documented in generic submittals of the TDI Owners'roup, "Generic Licensing Submittal for Emergency Diesel Generator-Conditions of License for Utilities with Enterprise Engine," dated November 30,
- 1992, and December 7,
1993.
2;0 EVALUATION The licensee provided an item-by-item discussion of the, License Condition requirements.
The items relate to the frequency of the major engine overhauls, inspection of EDG components (connecting rod assemblies, cylinder and turbochargers),
performance of air roll tests and requirements to be met prior to restart following the first refueling outage.
The bases for the proposed change is documented in the TDI Owners'roup reports submitted November 30,
- 1992, and December 7,
1993.
These generic reports are currently under review by the staff and it is expected that the
-'staff's generic SE will be issued in the near future.
The staff has completed its review of the operational database and inspection results of the TDI engines over the past eight years.
The staff's review of the operational database and inspection results submitted by the November 30,
- 1992, TDI Owners'roup report, as revised December 7,
1993, did not reveal any unacceptable findings.
The results of the end of Cycle 2, five-year component inspections at SHNPP have shown minimal or no wear on major engine components and very few other component-related problems.
The staff finds, therefore, that the proposed deferment of the diesel engine teardown inspection requirement until the end of Operating Cycle 6 does not affect any parameters that relate to the margin of safety as defined in the SHNPP Technical Specifications, and that the proposed changes do not involve a
significant reduction in a margin of safety.
Based on the above review, the staff concludes that proposed change to defer License Condition 2.C.(8) requiring the TDI complete engine overhaul from Refueling Outage No.
5 to Refueling Outage No.
6 will not result in a reduction in engine reliability, and therefore is acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the State of North Carolina official was notified of the proposed issuance of the amendment.
The State official had no comments.
r
- 4. 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 (58 FR 32378).
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.
5.0 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 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.
