SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO ANENDNENT NO. 123 TO FACILITY OPERATING LICENSE NO. NPF-12 SOUTH CAROLINA ELECTRIC & GAS CONPANY SOUTH CAROLINA PUBLIC SERVICE AUTHORITY VIRGIL C. SUP9tER NUCLEAR STATION. UNIT NO. 1 DOCKET NO. 50-395

1.0 INTRODUCTION

By letter dated October 29, 1993, as supplemented March 11, 1994, May 18, 1994, September 20, 1994, and October 20, 1994, South Carolina Electric & Gas Company (the licensee) submitted a request for changes to the Virgil C. Summer Nuclear Station, Unit No. 1 (Summer Station), Operating License and Technical Specifications (TS).- The proposed changes supported the installation of new; steam generators at Summer Station. The staff performed a Safety Evaluation and granted Operating License Amendment No. 119 on November 18, 1994.

However, Operating License Amendment No. 119 inadvertently did not delete License Conditions 2.C.13, 2.C.14, and 2.C.32 as requested by the licensee.

This Safety Evaluation is directed at correcting this omission.

The amendment-was originally noticed on February 16, 1994 (59 FR 7698).

It was renoticed on April 28,1994.(59 FR 22012), based on the no significant hazards determination contained in the licensee's March 11, 1994, submittal.

A Notice of Correction was published in the Federal Reaister on June 30, 1994 (59 FR 33795), correcting the amendment request date in the second notice from October 29, 1993, to March 11, 1994.

2.0 EVALUATION The' staff's Novemoer 18, 1994, Safety Evaluation addressed the TS changes requested by the licensee, but did not address the deletion of related License Conditions 2.C.13, 14, and 32. These license conditions were originally issued for the Model D3 steam generators. The Model D3-steam generators were replaced by Delta 75 steam generators during Summer Station's 1994 refueling outage.

In the licensee's October 29, 1993, letter, the licensee stated that these license conditions "... concern the Model D3 Steam Generators and have been considered in the design of the Delta 75 model." The individual license conditions are discussed below:

2.C.(13) Steam Generator Insnection Ports (Section 5.4.2. SER)

Prior to startup after the first refueling outage, SCE&G shall install steam generator inspection ports at the locations specified in Section 9504030021 950329 "

_, i 5.4.2 of the Safety Evaluation Report unless justification is submitted to the NRC staff for not installing such ports and wri.tten approval is given by the NRC staff.

Access ports have been incorporated into the design of the Delta 75 steam

. generators as described in WCAP-13480, " Westinghouse Delta 75 Steam Generator Design and Fabrication Information for the Virgil C. Summer Nuclear Station,"

August 1992.

2.C.(14) Model D-3 Steam Generator (Section 5.4.2. SSER #5) t The licensee shall conduct the inspection, testing and monitoring program as described in 0.W. Dixon's letter of May 3, 1983.

The licensee shall not make any major modifications to this program unless prior NRC approval is received.

Major modifications are defined as:

a.

Elimination of any identified testing, inspection, or monitoring, j

b.

Changes in the frequency of performing the identified testing, i

inspection or monitoring, and c.

Reduction in the scope of any of the identified testing, inspection, or monitoring.

.i i

The current Surveillance Requirements 4.4.5.0 through 4.4.5.5 delineate the appropriate steam generator inspection, testing, and monitoring requirements.

2.C.(32)

Steam Generator Tube Vibration (ASLB Suoolemental Partial Initial Decision. Auaust 4.1982.Section VIII.10)

Prior to operation at full power, SCE&G shall satisfy the NRC staff that appropriate surveillance measures and remedial action plans have been implemented with respect to the steam generator tube failure problem.

The current Surveillance Requirement 4.4.5.0 through 4.4.5.5 delineate the appropriate steam generator inspection, testing, and monitoring requirements.

Therefore, for the reasons stated the NRC staff has concluded that License Conditions 2.C.13, 2.C.14, and 2.C.32 are not applicable for the Delta 75 steam generators installed at Summer Station and their deletion is appropriate.

3.0 STATE CONSULTATION

In accordance with the Commission's regulations, the State of South Carolina official was notified of the proposed issuance of the amendment. The State official had no comments.

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 and change surveillance requirements. 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 exposurs The Commission has previously issued proposed findings that the amendment involves no significant hazards consideration, and there has been no _public comment on such findings (59 FR 7698 and 59 FR 22012). 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.
