SUBJECT: NOTIFICATION OF BROWNS FERRY NUCLEAR PLANT - COMPONENT DESIGN BASES INSPECTION - NRC INSPECTION REPORT
05000259/2009008, 05000260/2009008, AND 05000296/2009008
Dear Mr. Swafford:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region II staff will conduct a com
ponent design bases inspection at your Browns Ferry Nuclear
Plant during the period of September 28 - November 20, 2009. The inspection team will be led by Mr. Robert Berryman, a Senior Reactor Inspector from the NRC's Region II Office. This
inspection will be conducted in accordance with the baseline
inspection proc
edure, Pr ocedure 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 June 18, 2009, Mr. Berryman confirmed, with Mr. Jim
Davenport 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 September 28-October 2, 2009.
- Onsite weeks: Weeks of October 19 - 23, November 2 - 6, and November 16 - 20, 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. Wa
lt Rogers, a Region II Senior Reactor Analyst, may accompany Mr. Berryman during the information
gathering visit to review pr
obabilistic risk a
ssessment data and identify risk significant components which will be exami
ned during the
inspection.
TVA 2 The enclosure lists documents that will be needed prior to the information gathering visi
t. Please contact Mr. Berryman with any questions prior to preparing materials listed in the enclosure and
provide the referenced information to the Region II office by September 15, 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. Berryman at (404) 562-4817 or me
at (404) 562-4519.
Sincerely,

Enclosure INFORMATION REQUEST FOR BROWNS FERRY NUCLEAR PLANT 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 Browns Ferry Nuclear 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
