VIRGIL C. SUMMER NUCLEAR STATION UNIT 1 (VCSNS)

RR-111-1 1 Pressure Relief Valve Surveillance and RR-4-01 (G) IST Pump and Valve Surveillance Requirements

1. ASME Code Component(s) Affected Third and Fourth Interval All Pumps and Valves contained within the Inservice Testing (IST) Program scope.

2. Applicable Code Edition and Addenda Third Interval (April 1, 2004 through December 31, 2013)

ASME OM Code (1998 Edition through 2000 Addenda)

Fourth Interval (January 1, 2014 through December 31, 2023)

ASME OM Code-2004 Edition, with Addenda through OMb-2006.

3. Applicable Code Requirement(s)

This request applies to the frequency specifications of the ASME OM Code as documented within letters issued for VCSNS 4th Ten Year Inservice Inspection Interval TAC NO MF1900. The frequencies for tests given in the ASME OM Code do not include a tolerance band. Reference letter from T. D. Gatlin (VCSNS) to Document Control Desk (NRC), "Request Relief from ASME Code Requirements in VCSNS 4th Ten Year Inservice Inspection Interval," dated May 16, 2013 (RC-13-0069)

[ML13140A008].

4. Reason for Request Pursuant to 10 CFR 50.55a(a)(3)(ii), an alternative is requested to the frequency specifications of the ASME OM Code. The basis of this request is that the Code requirements present an undue hardship without a compensating increase in the level of quality or safety. VCSNS is requesting to apply Code Case OMN-20, Inservice Test Frequency as published in ASME OM-2012. VCSNS intends to apply the code case OMN-20 for the remainder of the third interval and into the fourth interval as documented within letters issued for VCSNS 4th Ten Year Inservice Inspection Interval TAC NO. MF1900.

5. Proposed Alternative and Basis for Use VCSNS is requesting to apply Code Case OMN-20, Inservice Test Frequency as published in ASME OM-2012. VCSNS intends to apply the code case OMN-20 for the remainder of the third interval and into the fourth interval as documented within letters issued for VCSNS 4th Ten Year Inservice Inspection Interval TAC NO. MF1900.

6. Duration of Proposed Alternative VCSNS is currently in the third 10 year interval that started April 1, 2004, and ends December 31, 2013. The proposed alternative identified will be utilized for the remainder of the third IST interval and into the fourth IST interval that is scheduled to begin January 1, 2014 and conclude on December 31, 2023.
