Fwd: Re: GL 2007-01, REQUEST FOR ADDITIONAL INFORMATION FOR DOMINION PLANTS I think this fell in the crack. I was in Chattanooga, and I forgot to send a formal request after I came back from Chattanooga. Is there anyway, you can respond to this e-mail, which was sent to you on October 18, 2007? I appreciate your help on this matter.

Please provide your response per GL 2007-01. I will send a formal request, probably by the end of this month.

The Electrical Engineering Branch staff has reviewed the licensees responses to GL2007-01 and has determined that the following additional information from Dominion is necessary to clarify the information that was provided in their response. The EEEB is requesting that this request for additional information be transmitted to the licensee, as applicable, for a written response. If you have any questions please contact Audrey Klett of the Electrical Engineering Branch.

The U.S. Nuclear Regulatory Commission (NRC) staff has received the cable failure histories for Kewaunee, Millstone, North Anna, and Surry in response to Generic Letter (GL) 2007 01, Inaccessible or Underground Power Cable Failures that Disable Accident Mitigation Systems or Cause Plant Transients.

The licensee prepared its response using the Nuclear Energy Institute (NEI) guidance, provided in an industry letter dated March 16, 2007, Guidance for Response to GL 2007 01. The NRC provided additional guidance on how licensees should determine which cable failures are within the scope of GL 2007 01 in the NRC letter dated April 13, 2007, from Michael J. Case (NRC) to James H.

Riley (Nuclear Energy Institute) (Agencywide Documents Access and Management System (ADAMS) Accession No. ML070940311). Confirm that the history was prepared in accordance with NRC guidance. If Dominions response to GL 2007-01

excluded cable failures based on the NEI guidance (i.e., not following the NRC guidance), provide the data for these failures as requested in GL 2007-01.
