SUBJECT:
MILLSTONE POWER STATION, UNIT NOS. 2 AND 3 - REQUEST FOR ADDITIONAL INFORMATION (RAI) REGARDING CONTROL ROOM HABITABILITY PROGRAM AMENDMENT REQUEST (TAC NOS. MD6115 AND MD6116)
Dear Mr. Christian:
By letter to the Nuclear Regulatory Commission (NRC) dated July 13, 2007, as supplemented by letters dated December 7, 2007, March 5, 2008, March 25, 2008, June 9, 2008 and June 26, 2008, Dominion Nuclear Connecticut, Inc. (DNC) submitted the proposed license amendment request for Millstone Power Station, Unit Nos. 2 and 3 to modify the Technical Specification (TS) requirements related to control room envelope habitability consistent with NRC-approved Technical Specification Task Force Traveler (TSTF) -448, Control Room Habitability, revision 3. The NRC staff has reviewed the request submitted by DNC and has identified a need for additional information as set forth in the enclosure.
The draft questions were sent to Mr. William Bartron, from your staff, to ensure that the questions were understandable, the regulatory basis for the questions was clear, and to determine if the information was previously docketed. On July 15, 2008, Mr. Gary Johnson, from your staff, indicated that DNC understands the issues and plans to submit a response by August 4, 2008. Please note that if you do not respond to this letter within this agreed response time or provide an acceptable alternate date in writing, we may reject your application for amendment under the provisions of Title 10 of the Code of Federal Regulations, Section 2.108.
If you have any questions, please contact me at (301) 415-3204.
Sincerely,
/ra/

Enclosure MILLSTONE POWER STATION, UNIT NOS. 2 AND 3 PROPOSED TECHNICAL SPECIFICATION CHANGE:
CONTROL ROOM HABITABILITY REQUEST FOR ADDITIONAL INFORMATION Dominion Nuclear Connecticut, Inc. (DNC) provided a supplement dated March 5, 2008, to its submittal dated July 13, 2007, (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML080660650 and ML071970463). In the response to NRC request for additional information question 1 (RAI 1), DNC stated that Millstone Power Station, Unit No. 2 (MPS2) conducts preventative maintenance and surveillance tests in lieu of a pressurization test to ensure that the MPS2 Control Room Envelope (CRE) boundary can perform its safety function. The response also noted that any criteria not met while performing these activities are documented and resolved in accordance with the MPS Corrective Action Program. The Nuclear Regulatory Commission (NRC) staff requests that the following information be provided in addition to the response provided to RAI 1 in the March 5, 2008, supplement.
RAI 1.a)
How will the MPS2 Technical Specification (TS) 6.27 description of the Control Room Habitability Program and associated License Condition incorporate the corrective action program and associated trending into a periodic assessment of the MPS2 CRE boundary? (The proposed text for MPS2 TS 6.27.d does not contain this information.)
RAI 1.b)
At what frequency will the periodic assessment of the MPS2 CRE boundary integrity be performed? What is the basis for this frequency?
