Technical Specification Task Force (TSTF) TSTF-448, Revision 3, "Control Room Habitability," was developed for plants with pressurized control room envelopes (CREs). The R.E. Ginna Nuclear Power Plant has a non-pressurized CRE. Note that the programs and manuals section of the standard technical specifications (STS), as modified by TSTF-448, Revision 3, paragraph (d) of Section 5.5.18, "Control Room Envelope Habitability Program," specifies a differential pressure (dp) test to be conducted between performances of inleakage testing for the purpose of providing input to a periodic assessment of the CRE boundary. The NRC staff recognizes that non-pressurized CREs may not be able to conduct a dp test. However, the staff believes that all plants requesting the adoption of TSTF-448 should include a method to collect data that will serve as input to a periodic assessment of the CRE boundary. This position is supported by the technical analysis section of TSTF-448, Revision 3, on page 8 where an explanation of the basis for paragraph (d) is provided. Consequently, the NRC staff is requesting that you provide a method to collect data, and an explanation of how you intend to use it to periodically assess the integrity of your CRE boundary. The method should, to the extent practicable, provide information that can be used in a manner similar to the manner in which the information is to be used that is requested by paragraph (d) of Section 5.5.18 of the programs and manuals section of the STS as modified by TSTF-448, Revision 3.
