SUBJECT: CATAWBA NUCLEAR STATION - COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT 05000413/2009006 AND 05000414/2009006

Dear Mr. Morris:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region II staff will conduct a component design bases inspection at your Catawba Nuclear Station during the period of July 6 - August 28, 2009. The inspection team will be led by W. R. Lewis, a Senior Reactor Inspector from the NRC's Region II Office. This inspection will be conducted in accordance with the baseline inspection procedure, Procedure 71111.21, Component Design Bases Inspection, issued August 19, 2008.

The inspection will evaluate the capability of risk significant / low margin components to function as designed and to support proper system operation. The inspection will also include a review of selected operator actions, operating experience, and modifications.

During a telephone conversation on April 27, 2009, Mr. Lewis confirmed, with Mr. Mark Sawicki of your staff, arrangements for an information gathering site visit and the three-week onsite inspection. The schedule is as follows:

• Information gathering visit: Week of July 6 - 10, 2009.

• Onsite weeks: Weeks of July 27 - 31, August 10 - 14, and August 24 - 28, 2009.

The purpose of the information gathering visit is to meet with members of your staff to identify risk-significant components and operator actions. Information and documentation needed to support the inspection will also be identified and gathered or requested. Mr. G. MacDonald, a Region II Senior Reactor Analyst, may accompany Mr. Lewis during the information gathering visit to review probabilistic ri sk assessment data and identify risk significant components which will be examined duri ng the inspection.

DEC 2 The enclosure lists documents that will be needed prior to the information gathering visi t. Please contact Mr. Lewis with any questions prior to preparing materials listed in the enclosure and provide the referenced information to the Region II office by June 19, 2009. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for the inspection preparation.

During the information gathering visit, the team leader will also discuss the following inspection support administrative details: office space; site, plant and information system access; required resources; and information exchange protocol.

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 ins pection 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).

Thank you for your cooperation in this matter. If you have any questions regarding the information requested or the inspection, please contact Mr. Lewis at (404) 562-4541 or me at (404) 562-4519.

Sincerely,/RA/

Enclosure INFORMATION REQUEST FOR CATAWBA NUCLEAR STATION COMPONENT DESIGN BASES INSPECTION

Please provide the information electronically in ".pdf" files, Excel, or other searchable format on CDROM. The CDROM should be indexed and possibly hyperlinked to facilitate ease of use. Information in "lists" should contain enough information to be easily understood to someone who has knowledge of pressurized water reactor technology.

1. From your most recent probabilistic safety analysis (PSA) excluding external events and fires, please provide: a. Two risk rankings of components from your site-specific probabilistic safety analysis (PSA) - one sorted by Risk Achievement Worth (RAW), and the other sorted by Birnbaum Importance. b. A list of the top 500 cutsets.

2. From your most recent probabilistic safety analysis (PSA) including external events and fires, please provide: a. Two risk rankings of components from your site-specific probabilistic safety analysis (PSA) - one sorted by Risk Achievement Worth (RAW), and the other sorted by Birnbaum Importance. b. A list of the top 500 cutsets.

3. Risk ranking of operator actions from your site specific PSA sorted by RAW. Provide copies of your human reliability worksheets for these items. 4. Any pre-existing evaluation or list of components and calculations with low design margins (i.e., pumps closest to the design limit for flow or pressure, diesel generator close to design required output, heat exchangers close to rated design heat removal, MOV risk-

margin rankings, etc.). 5. A list of station applicability evaluations/reviews performed and document ed in the station corrective action program in the past two years for industry events, critical equipment failures, and safety related equipment vul nerabilities (as communicated by NRC generic communications, industry communications, 10 CFR Part 21 notifications, etc.). 6. A list of operability evaluations completed within the last two years, sorted by associated component or system. 7. A list of common-cause failures of components that have occurred at Catawba Nuclear Station and have been identified within the last five years. 8. A list of equipment currently planned for upgrade/improvement by the site (e.g. "ONE" List), including a description of the reason(s) why each component (i.e. not a programmatic or system level concern) is on that list and summaries (if available) of your plans to address those reasons. 9. A list of equipment currently in RIS 05-020 (formerly GL 91-18) status, or in MR (a)(1) status. 10.
