Upcoming BFN DBAI (programs) inspection (IP71111.21N.02)
Date: Tuesday, March 08, 2022 1:00:10 PM Attachments: 2022 BFN - POV Inspection Information Request.docx BFN POV Data-rev 1.docx
- Justin,
Thanks for working with me so far to get the Design Basis Assurance (programs)
Inspection, also known as the Power Operated Valve inspection, started. As I mentioned previously, please treat the highlighted dates in the POV Inspection Information Request as tentative until we can firm up the dates for the information gathering visit.
Please see the attached request for some initial information that will help the team select our final inspection sample. Part of the request is contained in the attached access database, BFN POV Data-rev 1.docx, which asks for specific data points relevant to the indicated valves to be entered into the database and provided back to us. (PLEASE NOTE:
the Access database is sent as a Word document in order to be able to transmit it via e-mail. You will need to change the file extension of the BFN POV Data-rev 1.docx file from
.docx to.accdb to convert it back into an Access file.) Please provide as much of the requested information as possible, if it is readily available.
The following information will help when filling out the database with the requested valve-specific information:
You may have to enable content before using-this is only done once and shouldnt pop up again. It is understood that not all fields will be entered. Also please note that when entering data into the various fields there is a text box at the bottom left of the data entry form that details to the person entering the data what needs to be entered. For example, when on the Docket field the text at the bottom will state Enter the Docket number last 3 digits. Also, when entering text in the comment field and it is desired to start a new line, it is necessary to hit control+enter to start a new line.
Feel free to reach out to me with any questions you may have regarding anything related to the inspection (inspection procedure, information request, etc.) and Ill do my best to get any questions/concerns addressed. Im looking forward to the inspection.

Browns Ferry Nuclear Plant - Design Bases Assurance Inspection (Programs)
Initial Information Request
Inspection Procedure: 71111.21N, Design Bases Assurance Inspection (Programs),
Attachment 21N.02, Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements, dated October 9, 2020 (ADAMS ML20220A667)
Inspection Dates: Information Gathering Visit: June 13-17, 2022 Preparation Week: July 11-15, 2022 Onsite Week 1: July 18-22, 202 2 Onsite Week 2: August 1-5, 2022
Inspection Report: 05000259, 260, 296/ 202 2011 (Standalone Inspection Report)
Inspectors: G. Ottenberg (Lead/Mechanical), TBD (Mechanical/Electrical ), and R. Waters (Mechanical-contractor)
The purpose of this letter is to notify you that three inspectors from Region II will conduct an inspection at your site in accordance with Inspection Procedure 71111.21N, Design Bases Assurance Inspection (Programs), Attachment 21N.02, Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements. This is not considered a team inspection. The inspection will evaluate the implementation of the programs regarding power operated valves (POVs) for compliance with 10 CFR 50.55a at the Browns Ferry Nuclear Plant.
The inspectors will select samples of components that are risk significant and within the scope of the program.
On June 13, 2022, Mr. Geoffrey Ottenberg, a Senior Reactor Inspector from the NRCs Region II office, will begin the inspection with an information gathering visit to the site, if pandemic conditions allow. The purpose of the visit is to become familiar with your program and procedures which are supposed to ensure your compliance with 10 CFR 50.55a for POVs. This will require meetings with members of your staff to discuss aspects of the program including any specific applicable regulatory commitments made by the site and your use of regulatory guides or industry standards. Your processes for generating field instructions for POV switch settings and test acceptance criteria from design documents is also expected to be discussed. Plant walkdowns to observe the potential inspection sample are expected to occur during the information gathering visit, if a site visit is made.
The enclosure lists documents that are needed prior to the information gathering visit. Please provide the referenced information to the Region II Office by June 6, 2022. Additional documents may be requested during the information gathering visit. The inspectors will try to minimize your administrative burden by specifically identifying only those documents required for inspection preparation. The additional information should be provided to the Inspectors in the Region II office by July 11, 2022. During the information gathering visit, Mr. Ottenberg will also discuss the following inspection support administrative details: (1) availability of knowledgeable plant engineering and licensing personnel to serve as points of contact during the inspection, (2) method of tracking inspector requests during the inspection, (3) computer access, (4) working space, (5) arrangements for site access, and (6) other applicable information.
