UNITEDSTATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 8805040057 880427 PDR ADOCK 05000400 P
PDR" SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO THE INSERVICE TESTING PROGRAM AND REQUESTS FOR RELIEF CAROLINA POWER 8 LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO.
50-400 INTRODUCTION The Code of Federal Regulations in 10 CFR 50.55a(g) requires that inservice test-ing (IST) of ASME Code Class 1, 2, and 3 pumps and valves shall be performed in accordance with Section XI of the ASME Boiler and Pressure Vessel Code and applicable
- addenda, except where specific written relief has been requested by the licensee and granted by the Commission pursuant to 10 CFR 50.55a.
In requesting relief, the licensee must demonstrate that conformance with certain requirements of the applicable Code edition and addenda is"impractical for its facility.
Regulations 10 CFR 50.55a(g)(6)(i) and 10 CFR 50.55a(3)(i) authorize the Commission to grant relief from these requirements and approve alternatives upon making the necessary findings.
This Safety Evaluation (SE) contains the NRC staff findings with respect to granting or not granting the relief requested as part of the licensee's IST program.
The IST program addressed in this report covers the first ten-year inspection interval from May 2, 1987 to May 2, 1997.
The licensee's program is described in a letter dated September 16, 1986.
Additional information and revisions were submitted in letters dated December 31,
- 1986, March 20,
- 1987, and December 4, 1987.
The program is based on the requirements of Section XI of the ASME Code, 1983 Edition, through the Summer of 1983 Addenda, and remains in effect until May 2, 1997, unless the program is modified or changed prior to the ten-year interval end date.
EVALUATION This IST program and the requests for relief from the requirements of Section XI have been reviewed by the staff with the assistance of its contractor, EGSG Idaho, Inc.
(EGSG).
In addition, EG&G and NRC staff members met with licensee representatives on August 5 and 6, 1986, in a working session to discuss ques-tions resulting from the review.
The Technical Evaluation Report (TER),
provided as Enclosure 1, is EGSG's evaluation of the licensee's inservice testing program and relief requests.
The staff has reviewed the TER and concurs with, and adopts, the evaluations and conclusions contained in the TER.
A summary of the pump and valve relief request determinations is presented in 1
Table 1.
The table also contains the term "agree" to indicate the staff concurrence in certain relaxations permissible under the Code which do not require relief.
Where relief is granted, the relief is based upon the ful-fillment of any commitments made by the licensee in its basis for each relief request and the alternate proposed testing.
Two relief requests were denied (TER Sections 4.4.1. I and 4.4. 1.3) and two relief requests were granted on an interim basis (TER Sections 3.5. I and
- 4. 10.3.2).
The licensee should refer to the specific TER section for a detailed discussion of these cases.
In addition, TER, Appendix C, lists the IST program anomalies which were identified during our review.
The licensee should resolve these anomalies in accordance with the staff positions.
Required program changes should be made within 90 days of receipt of this SE.
In TER Sections 3.7, 3.8 and 4.2. 1, the licensee has demonstrated that it is impractical to perform the Code specified testing and that the proposed alternative would provide an acceptable level of quality and safety.
CONCLUSION Based on the review of the licensee's IST program and relief requests, the staff concludes that the IST program, as evaluated and modified by this SE, will provide reasonable assurance of the operational readiness of the pumps and valves covered by the IST program to perform their safety related functions.
The staff has determined that, pursuant to 10 CFR 50.55a(g)(6)(i),
granting relief where the Code requirements are impractical is authorized by law and will not endanger life or property, or the common defense and security.
The staff has also concluded that granting relief is otherwise in the public interest considering the burden that could result if the requirements were imposed on the facility.
In TER Sections 3.7, 3.8 and 4.2. 1, the licensee has demonstrated that it is impractical to perform the Code specified testing and that the proposed alternative would provide an acceptable level of quality and safety.
For these three items, relief is granted pursuant to 10 CFR 50.55a(3)(i).
During the review of the licensee's inservice testing
- program, the staff has identified certain misinterpretations or omissions of Code requirements.
These items are summarized in the TER, Appendix C.
The IST program of SHNPP, through the submittal dated December 4, 1987, is acceptable for implementation provided that the items noted above are corrected promptly.
Relief requests contained in any subsequent revisions may not be implemented without prior approval by NRC.
