VIRGIL C. SUMMER NUCLEAR STATION (VCSNS) DOCKET NO. 50/395 OPERATING LICENSE NO. NPF-12 ASME SECTION XI RELIEF REQUEST - ADDENDUM (NRR 950001) Ref: G. J. Taylor to Document Control Desk dated December 20,1995 (RC-95-0315) t i South Carolina Electric & Gas Company (SCE&G) hereby submits the foliowing addendum to our letter dated December 20,1995 (NRC TAC # M94364), requesting relief from the ASME Section XI requirements for Class 1 and 2 insulated pressure retaining bolted connections which receive VT-2 Visual Examination during the performance of System Pressure Testing. The enclosure contains additional components for which this relief is requested. This relief is modeled after Code Case N-533, expanded to include specified Class 2 connections inside containment. This relief is to exempt the applicable Class 1 and 2 pressure retaining bolted connections that are insulated,in systems borated for the purpose of reactivity control. Specifically, SCE&G requests to exempt the additional applicable connections from the requirements of ASME Section XI IWA 5242(a), which specifies that insulation must be removed from pressure retaining bolted connections for VT-2 visual examination during the performance of System Pressure Testing. As an alternate, SCE&G shall remove the insulation and conduct the VT-2 visual examination of pressure retaining bolted connections on applicable Class 1 connections once per refueling outage at static or atmospheric pressure. Applicable Class 2 connections will be similarly inspected once each inspection period during a refueling outage. Insulation will then be reinstalled and upon repressurization of a l bolted connection, a four-hour hold time will be utilized to assess potential leakage. SCE&G contends that the proposed alternate testing provides the equivalent, acceptable level of quality and safety as that provided by the Code. SCE&G desires relief from the above requirements so as not to create an undue hardship without a compensating increase in quality or safety. ) SCE&G requests that the NRC review and approve this addendum as soon as possible, in order to support inspection activities scheduled to begin in April,1996. 9604010427 960327 PDR ADOCK 05000395 g i p PDR i
