REQUEST FOR ADDITIONAL INFORMATION REVISION TO TECHNICAL SPECIFICATIONS CONTROL ROOM ENVELOPE HABITABILITY WOLF CREEK NUCLEAR OPERATING CORPORATION DOCKET NO. 50-482

By letter dated January 15, 2008 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML080240232), Wolf Creek Nuclear Operation Corporation (WCNOC) requested an amendment to the Technical Specifications (TSs) for the Wolf Creek Generating Station. The requested amendment is to revise TS requirements related to control room envelope habitability in accordance with Technical Specification Task Force (TSTF) TSTF-448, Revision 3, "Control Room Habitability." The Nuclear Regulatory Commission staff det ermined that additional information is needed in order to complete its review.

1. WCNOC letter dated January 15, 2008, Page 3 of 5 of Attachment I (the last paragraph of Section 2.2.1), states, in part, that "in TS 3.7.10, TS 5.5.18 and TS Bases 3.7.10 the phrase 'control room envelope (CRE)' is replaced with 'CRE and control building envelope (CBE) boundary' and CRE is replaced with CRE and CBE in several places."

However, in insert 5.0-21 (Page 8 of 9 of Attachment II), Sections 5.5.18.d and 5.5.18.f, "control room" is used instead of "control room envelope" or "CRE and CBE boundary".

The use of phrase "control room" is not consistent with the explanation on page 3 of 5 in Section 2.2.1 of Attachment I.

In addition, this appears inconsistent with the intent of TSTF-448, Revision 3, as indicated in the technical analysis Section on Page 9 of TSTF-448, where Bases Changes are discussed. On page 9, it is stated that "the Bases are revised to use the terms 'control room envelope (CRE)' and 'CRE boundary' instead of the ambiguous term

'control room.' The definition of 'control room' and 'control room envelope boundary' are added to the background section of the Bases."

Please clarify your intent with the use of "control room" in insert 5.0-21 on Page 8 of 9, Sections 5.5.18.d and 5.5.18.f of your submittal.

2. In accordance with TSTF-448, the title of the program represented by Section 5.5.18 should be "Control Room Envelope Habitability Program," instead of "Control Room Habitability Program," as stated by Insert for Page 5.0-21. The diffe rence is minor, however, the title in the TSTF places a more appropriate emphasis on the control room envelope. Please consider revising the title of the program to be consistent with the TSTF.

3. Section 5.5.17.e of your submittal is also inconsistent with TSTF-448, Revision 3, in that there is no discussion of CRE occupants' exposure to hazardous chemicals such as is reflected in the REQUIRED ACTION of TS 3.7.10.B.2, where there is assurance that the CRE occupants are protected from hazardous chemicals regardless of quantities stored on site-now or in the future. The NRC staff is aware of the discussion provided in Enclosure section 2.2.3 of Attachment I of the WCNOC submittal and believes that the discussion does not adequately address the intent of TSTF-448. Therefore, please consider updating Section 5.5.17.e of your submittal to address CRE occupants' exposure to hazardous chemicals consistent with the intent of TSTF-448, Revision 3, Section 5.5.18.e.
