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 component 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 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 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. Walt Rogers, a
Region II Senior Reactor Analyst, may accompany Mr. Berryman during the information
gathering visit to review probabilistic risk assessment data and identify risk significant
components which will be examined during the inspection.

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 component 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 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 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. Walt Rogers, a

Region II Senior Reactor Analyst, may accompany Mr. Berryman during the information

gathering visit to review probabilistic risk assessment data and identify risk significant

components which will be examined during the inspection.

The enclosure lists documents that will be needed prior to the information gathering visit. 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 inspection in the NRC Public Document Room

or from the Publicly Available Records (PARS) component of NRC's document system

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 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

gathering trip: name, title, phone number, and e-mail address.
