Enclosure REQUEST FOR OCONEE NUCLEAR POWER PLANT COMPONENT DESIGN BASES INSPECTION

Please provide the information electronically in ".pdf" files, Excel, or other searchable format on

CD/DVD-ROM. The CD/DVD-ROM 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 documented in the station corrective action program in the past two years for industry events, critical equipment

failures, and safety related equipment vulnerabilities (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 Oconee Nuclear Power Plant 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. Contact information for a person to discuss PRA information prior to the information gathering trip: name, title, phone number, and e-mail address.

2 Enclosure 11. Provide two sets of PI&D drawings (11x17) for safety-related systems and two sets of one line electrical drawings ( 11X17) for safety related systems (for onsite week of July 11-

July 15, 2011) 12. Provide six copies of FSAR (CD/DVD-ROM only) (for onsite week of July 11- July 15, 2011) 13. Provide six copies of Technical Specifications and Bases (CD/DVD-ROM only) (for onsite week of July 11- July 15, 2011)
