"Preliminary Significance Determination For A Greater Than Green Finding (NRC Inspection Report 50-305/2004-09) - Kewaunee Containment Equipment Hatch Interference," dated February 18, 2005.

Nuclear Regulatory Commission (NRC) Inspection Report 50-305/2004-09 documented an issue associated with prompt closure of the containment equipment hatch at the Kewaunee Nuclear Power Plant (KNPP). In reference 1, the NRC provided the Nuclear Management Company, LLC, (NMC) with the NRC's preliminary significance determination for the performance deficiency and offered NMC an opportunity to present our perspectives prior to finalization of the NRC's significance determination.
NMC has requested a Regulatory Conference to present our perspectives on the facts and assumptions used. This Regulatory Conference is scheduled for March 17, 2005, at the NRC Region IlIl Headquarters. Additionally, the NRC encouraged NMC to submit supporting documentation for the requested Regulatory Conference before the scheduled date of the conference.
Since the issuance of the Inspection Report, NMC has performed further analysis to better characterize the probabilistic risk assessment (PRA) assumptions and inputs.
Enclosed are the latest results of that work for use at the requested Regulatory Conference. Reference 2 indicated that additional information, that may be helpful in assessing this issue, will be submitted within several days. This letter contains the majority of that information.
