SUBJECT:
DONALD C. COOK NUCLEAR PLANT, UNITS 1 AND 2 - FINAL ACCIDENT SEQUENCE PRECURSOR ANALYSIS OF AUGUST 2001 OPERATIONAL CONDITION
Dear Mr. Nazar:
Enclosed for your information is the final Accident Sequence Precursor (ASP) analysis of an operational conditions which were discovered at the Donald C. Cook Nuclear Plant (D. C.
Cook), Units 1 and 2, in August 2001. These conditions were documented in the U. S. Nuclear Regulatory Commission (NRC) Inspection Reports No. 50-315/316/01-17, dated March 21, 2002. We prepared the final analysis based on our review and evaluation of comments from the licensee and the NRC staff on the preliminary analysis of this event. The analysis was clarified as a result of comments. There were also minor changes to the quantitative result, however, the conclusions remain unchanged. Our responses to your specific comments are included in Appendix B to the enclosed report. Our review of your comments employed the criteria contained in the material which accompanied the preliminary analysis. The results of the final ASP analysis indicate that this condition is a precursor [i.e., the importance or change in core damage probability (CCDP) >1E-6].
Please contact me at 301-415-1345 if you have any questions regarding the enclosure. We recognize and appreciate the effort expended by you and your staff in reviewing comments on the preliminary analysis.
Due to the potential sensitivity of the information described in the enclosed ASP analysis, the staff has not made this enclosure publicly available.
Sincerely,
/RA/
John F. Stang, Senior Project Manager, Section 1 Project Directorate III Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket Nos. 50-315 and 50-316
