Dear Sir / Madam:

Subject:

VIRGIL C. SUMMER NUCLEAR STATION (VCSNS) UNIT 1 DOCKET NO. 50-395 OPERATING LICENSE NO. NPF-12 REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO CORRECT AN ADMINISTRATIVE ERROR

NUREG-0932 Virgil C. Summer Nuclear Station Unit No. 1 Technical Specifications issued August 1982 (ADAMS ML041000447)

Proposed Guidance for Correction of Technical Specification Typographical Errors, SECY-96-238, dated November 19, 1996 (ADAMS Legacy Library Accession No. 9611250030)

This letter requests Nuclear Regulatory Commission's (NRC) approval of a correction to an error in Virgil C. Summer Nuclear Station (VCSNS) Technical Specifications (TS). This error was inadvertently introduced during original issuance of the station's TS.

This error was neither addressed in the notice to the public, nor reviewed by the NRC, and thus falls within the scope of the guidance provided by SECY-96-238 (Reference 2) for corrections.

Attachment I describes the error and corrections. Attachment II provides the requested correction noted. Attachment III contains the corrected page.

This document contains no new commitments.

DOCKET NO. 50-395 OPERATING LICENSE NO. NPF-12 Attachment I Description of Technical Specification Error

Document Control Desk Attachment I RC-18-0079 CR-18-00486 Page 2 of 2 Requested Action Consistent with the information contained in SECY-96-238, Proposed Guidance for Correction of Technical Specification Typographical Errors, South Carolina Electric & Gas (SCE&G) is requesting a correction of an error that was inadvertently introduced into the Virgil C. Summer Nuclear Station (VCSNS) Unit 1 Technical Specifications (TS).

1. Typographical Error The error was introduced into the VCSNS TS during original issuance. The specification of the error and proposed corrections are described below:

Review of TS 3.1.2.6 - Borated Water Sources - Operating and TS 3.5.4 - Refueling Water Storage Tank revealed an error within the time to Mode 3 for inoperable Refueling Water Storage Tank (RWST). The discrepancy is TS 3.1.2.6 allows for 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> to Mode 3, while TS 3.5.4 only allows 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to Mode 3. A total of 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> to Mode 3 requirement should apply to both action statements.

TS 3.1.2.6 Action B states:

"With the refueling water storage tank inoperable, restore the tank to OPERABLE status within one hour or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />."

TS 3.5.4 Action states:

"With the refueling water storage tank inoperable, restore the tank to OPERABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />."

TS 3.5.4 Action should state "restore the tank to OPERABLE status within one hour or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />". The words "the next" need to be added after "within" to TS 3.5.4. This addition will provide the correct total of 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> to the Mode 3 requirement. The marked-up TS can be found in Attachment II.

2. Correction to Affected Pages SECY-96-238 (Reference 2) provides guidance to correct inadvertent errors in the Technical Specifications. This error described above was neither posted in the public notices nor was it reviewed by NRC as part of the license amendment process. Therefore, it may be corrected without a license amendment.

Accordingly, upon approval from the NRC, a corrected TS Page 3/4 5-9 will be issued to all holders of controlled TS.
