SUBJECT:

BROWNS FERRY NUCLEAR PLANT - NUCLEAR REGULATORY COMMISSION TEAM INSPECTION REPORT 05000259/2018011, 05000260/2018011, AND 05000296/2018011

Dear Mr. Shea:

On December 12, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Browns Ferry Nuclear Plant, Units 1, 2, and 3. The NRC inspectors discussed the results of this inspection with Mr. D. L. Hughes, Site Vice President, and other members of your staff. The results of this inspection are documented in the enclosed report.

The inspection examined activities conducted under your license as they relate to the implementation of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders (EA-12-049 and EA-12-051) and Emergency Preparedness Communication/Staffing/Multi-Unit Dose Assessment Plans, your compliance with the Commissions rules and regulations, and with the conditions of your operating license. Within these areas, the inspection involved examination of selected procedures and records, observation of activities, and interviews with station personnel.

The NRC inspectors did not identify any finding or violation of more than minor significance.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding. If you have any questions, please contact me at 404-997-4513.

Sincerely,

/RA/

INSPECTION SCOPE

Inspections were conducted using the appropriate portions of Temporary Instruction (TI)

procedure 2515/191, Implementation of Mitigation Strategies and Spent Fuel Pool (SFP)

Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi-Unit Dose

Assessment Plans, (ADAMS Accession No. ML18191B074). Documents reviewed by

inspectors are listed in the documents reviewed section of this report. The inspectors reviewed

selected procedures and records, observed activities, and interviewed personnel to assess

licensee performance and compliance with Commission rules and regulations, license

conditions, site procedures, and standards.

OTHER ACTIVITIES - TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL

TI 2515/191 - Inspection of the Implementation of Mitigation Strategies and Spent Fuel Pool

Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi-Unit Dose

Assessment Plans

Inspectors verified plans for complying with NRC Orders EA-12-049, Order Modifying

Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis

External Events, (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML12056A045) and EA-12-051, Order Modifying Licenses with Regard to

Reliable Spent Fuel Pool Instrumentation, (ML12054A679) were in place and were being

implemented by the licensee. Additionally, the inspection verified implementation of staffing and

communications information provided in response to the March 12, 2012, request for

information letter (ML12053A340) and dose assessment information provided per COMSECY-

13-0010, Schedule and Plans for Tier 2 Order on Emergency Preparedness for Japan Lessons

Learned, dated March 27, 2013 (ML12339A262).

(1) Based on samples selected for review, the inspectors verified that the licensee

satisfactorily implemented appropriate elements of the Diverse and Flexible Coping

Strategies (FLEX) as described in the plant-specific submittals and the associated safety

evaluation (ML18236A331) and determined that the licensee is in compliance with NRC

Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation

Strategies for Beyond-Design-Basis External Events (ML12056A045). The inspectors

verified the licensee satisfactorily:

a) developed and issued FLEX Support Guidelines (FSGs) to implement the FLEX

strategies for postulated external events;

b) integrated their FSGs into their existing plant procedures such that entry into and

departure from the FSGs were clear when using existing plant procedures;

c) protected FLEX equipment from site-specific hazards;

d) developed and implemented adequate testing and maintenance of FLEX equipment

to ensure their availability and capability;

e) trained their staff to ensure personnel proficiency in the mitigation of

beyond-design basis events; and

f) developed the means to ensure the necessary off-site FLEX equipment would be

available from off-site locations.

(2) Based on samples selected for review, the inspectors verified that the licensee

satisfactorily implemented appropriate elements of the FLEX strategy as described in the

plant specific submittals and the associated safety evaluation (ML18236A331) and

determined that the licensee was in compliance with NRC Order NRC Order EA-12-

051, Order Modifying Licenses With Regard to Reliable Spent Fuel Pool

Instrumentation (ML12054A679). The inspectors verified that the licensee satisfactorily:

a) installed the spent fuel pool (SFP) instrumentation sensors, cabling and power

supplies to provide physical and electrical separation as described in the plant

specific submittals and safety evaluation;

b) installed the SFP instrumentation display in the location, environmental conditions

and accessibility as described in the plant specific submittals;

c) trained their staff to assure personnel proficiency with the maintenance, testing, and

use of the SFP instrumentation; and

d) developed and issued procedures for maintenance, testing and use of the reliable

SFP instrumentation.

(3) The inspectors reviewed information provided in the licensees dose submittal and in

response to the NRCs March 12, 2012, request for information letter (ML12053A340),

and verified that the licensee satisfactorily implemented enhancements pertaining to

Near-Term Task Force (NTTF) Recommendation 9.3 response to a large-scale natural

emergency event that results in an extended loss of all alternating current (ac) power

(ELAP) to all site units and impedes access to the site The inspectors verified the

following:

a) the licensee satisfactorily implemented required staffing changes to support a

ELAP scenario;

b) emergency preparedness (EP) communications equipment and facilities are

sufficient for dealing with a ELAP scenario; and

c) the licensee implemented dose assessment capabilities (including releases from

SFPs) using the licensees site-specific dose assessment software and approach.

The inspectors verified that noncompliances with requirements, and standards identified during

the inspection were entered into the licensee's corrective action program as appropriate.

INSPECTION RESULTS

No findings were identified.

EXIT MEETINGS AND DEBRIEFS

No proprietary information was retained by the inspectors or documented in this report.

On December 12, 2018, the inspectors presented the inspection results to Mr.

D. L. Hughes,

Site Vice President, and other members of the licensees staff.
