March 19, 2004 MEMORANDUM TO: Darrell J. Roberts, Acting Chief, Section 2 Project Directorate I Division of Licensing Project Management Office of Nuclear Reactor Regulation FROM: Victor Nerses, Senior Project Manager, Section 2 /RA/

Project Directorate I Division of Licensing Project Management Office of Nuclear Reactor Regulation

SUMMARY

OF MEETING HELD ON FEBRUARY 18, 2004, BETWEEN STAFF OF THE NUCLEAR REGULATORY COMMISSION AND DOMINION NUCLEAR CONNECTICUT, INC.

Staff from the Nuclear Regulatory Commission (NRC), met with Dominion Nuclear Connecticut, Inc. (DNC) on February 18, 2004, at Millstone Power Station, Unit No. 3 (MP3). The purpose of the meeting was to allow the NRC staff to examine the installed (recent items as well as those items that had previously been installed) fire protection system in the MP3 cable spreading area (CSA) and other areas as necessary. A list of key items of specific interest that the NRC staff pursued during this visit is provided in Attachment 1. A list of the areas visited as part of the plant walk-downs is provided in Attachment 2. A list of attendees is provided as Attachment 3.

The meeting announcement is in ADAMS (Accession No. ML040330525.).

The NRC staff achieved a better understanding of the uniqueness of the MP3 cable spreading room, the extensive amount of fire fighting equipment staged in the cable spreading room, the fire fighting techniques and procedures that will be in place, and the problems that are created for operators in the control room or at the remote shutdown panel when carbon dioxide (CO2) is discharged in the cable spreading room. Part of this understanding includes how these measures that have been taken will compensate for the transition from automatic to manual actuation of the CO2 system.

DNC agreed to formally submit for NRC staff review detail information on the measures that have been taken such as the fire fighting equipment stationed for a fire in the CSA, incipient fire detection system, training, procedural upgrades, monitoring CO2 and oxygen (O2), etc., and information addressing the human factor aspects as a result of the change to a manually-actuated CO2 system. DNC noted that the target for their submital is by the end of March 2004.
