Dear Sir / Madam:
Subject:
VIRGIL C. SUMMER NUCLEAR STATION (VCSNS)
DOCKET NO. 50/395 OPERATING LICENSE NO. NPF-12 RESPONSE TO NRC GENERIC LETTER 2003-01 CONTROL ROOM HABITABILITY - CHANGE TO ACTIVITY SCHEDULE
Reference:
S. A. Byrne (SCE&G) Letter to Document Control Desk (NRC) RC-03-0167 60-DAY RESPONSE TO NRC GENERIC LETTER 2003-01 CONTROL ROOM HABITABILITY, August 8,2003 On June 12, 2003, the U.S. Nuclear Regulatory Commission (NRC) issued NRC Generic Letter 2003-01 to request that utilities provide information that demonstrates that the control room at their facility complies with the current licensing and design bases and applicable regulatory requirements (GDC 1, 3, 4, 5, and 19), and that suitable design, maintenance and testing control measures are in place for maintaining this compliance.
South Carolina Electric & Gas Company (SCE&G) acting for itself and as agent for South Carolina Public Service Authority, submitted the referenced letter as a 60-day response action.
The referenced response was required by the generic letter as SCE&G determined that all necessary actions to provide the requested information could not be achieved within the prescribed 180 days.
In the referenced letter, SCE&G identified a schedule of activities that were projected to be accomplished in 2004. This schedule was structured to allow for review and evaluation of the required testing along with the implementation of any program revisions to be followed by a submittal of results. SCE&G also stated that should it become apparent that activities would extend beyond the projected completion date; an updated schedule would be provided.
Due to vendor availability restrictions, SCE&G was not able to accomplish the necessary testing, resultant evaluations, and program changes identified previously for 2004. This letter provides the revised activity schedule based on vendor availability for test performance.
Also, our submittal of results has been delayed accordingly.

Document Control Desk Letter Attachment C-03-1931 RC-05-0003 Page 1 of 1 Revised Schedule for Response to Generic Letter 2003-01 The following activities have been performed to support activities to be accomplished by mid-year 2005:
Performance of a system assessment to identify potential inleakage paths that are candidates for pre-test maintenance or design modifications.
- Determination of whether Control Room Habitability systems are consistent with the Licensing Bases.
- Determination of performance characteristics of the control room envelope (CRE),
the CRE ventilation systems, and systems that serve or traverse areas within or located adjacent to the CRE.
- Selection of the source term methodology (i.e., alternate or TID-14844 source terms) to be utilized in radiological assessments.
- Calculation of radiological (per RG 1.195 or 1.183) and chemical hazards (per RG 1.78) consequences with allowable inleakage values.
Activities to be accomplished by mid-year 2005 include the following:
Performance of a baseline ASTM E741 integrated test of the CRE during all pertinent operating modes.
- Performance of a qualitative assessment to ensure that the plant can be safely shutdown from either the control room or alternate shutdown panel during an internal or external smoke event.
Comparison of test data to allowable inleakage values, and initiation of any necessary maintenance and/or modifications.
- Establishment of a Control Room Habitability maintenance and monitoring program.
VCSNS will provide the information requested in Generic Letter 2003-01 within 3 months following the completion of these activities. SCE&G will address any coordinating industry developments in the VCSNS response.
Should it become apparent that activities will extend beyond the projected completion date, an updated schedule will be provided.
