SUBJECT:
D. C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2 - INFORMATION REQUEST FOR A BIENNIAL NRC BASELINE SAFETY SYSTEM DESIGN AND PERFORMANCE CAPABILITY INSPECTION
Dear Mr. Nazar:
On September 6, 2005, the NRC will begin a required biennial inspection of safety system design and performance capability (SSDPC) at your D. C. Cook Nuclear Power Plant. This inspection will be performed in accordance with the guidance in NRC baseline inspection procedure 71111.21. The system/components to be reviewed during the SSDPC portion of the baseline inspection are the 250 volt direct current (Vdc) power systems and the auxiliary feedwater system (AFW).
Experience has shown that the baseline design inspections are extremely resource intensive both for the NRC inspectors and the utility staff. In order to minimize the impact that the inspection has on the site and to ensure a productive inspection for both sides, we have enclosed a request for documents needed for the inspection. The documents have been divided into three groups.
The first group lists information necessary in order to ensure the inspection team is adequately prepared for the inspection. This information should be available to the Regional Office by no later than August 8, 2005. Insofar as possible, this information should be provided electronically to the lead inspector.
The second group of documents requested are those items which the team will review or need access to during the inspection. This list includes a reference to specific documents resulting from the teams review of the initially supplied information. This supplemental request will be provided to your staff by no later than August 31, 2005. Ensuring that these documents are as complete as possible will minimize the number of documents requested during the inspection.
The last group of information requested is necessary to aid the inspection team in tracking issues identified as a result of the inspection. It is requested that this information be provided to the lead inspector as the information is generated during the inspection.
M. Nazar The lead inspector for this inspection is Ms. Patricia Lougheed. If there are any questions about the material requested, or the inspection, please call the lead inspector at (630) 829-9760 or e-mail her at vpl@nrc.gov.
In accordance with 10 CFR 2.390 of the NRC's Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/
