ML19210E896 CATAWBA NUCLEAR STATION - Design Bases Assurance Inspection (Programs)

Initial Information Request Inspection Procedure: 71111.21N, Design Bases Assurance Inspection (Programs),

Attachment 1, Environmental Qualification under 10 CFR 50.49 Programs, Processes, and Procedures, dated December 8, 2016 (ADAMS ML16340B001)

Inspection Dates: Information Gathering Visit: 09/30/2019 - 10/04/2019 Preparation Week: 10/21/2019 - 10/25/2019 Onsite Week 1: 10/28/2019 - 11/01/2019 Onsite Week 2: 11/18/2019 - 11/22/2019 Inspection Report: 05000413/2019010 AND 05000414/2019010 (Standalone Inspection Report)

Inspectors: M. Greenleaf (Lead), B. Collins, and M. Riley 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 1, Environmental Qualification under 10 CFR 50.49 Programs, Processes, and Procedures. This is not considered a team inspection.

The inspection will evaluate the implementation of the Catawba Nuclear Stations equipment environmental qualification (EQ) program, as required by 10 CFR 50.49, and the Catawba Nuclear Station Units 1 & 2 Operating Licenses. The inspectors will select samples of components that could be subjected to harsh environments before or during the mitigation of selected design basis accidents.

On September 30, 2019, Dr. Michael Greenleaf, a Reactor Inspector from the NRCs Region II office, will begin the inspection with an information gathering visit to the site. The purpose of the visit is to become familiar with your EQ program and procedures. This will require meetings with members of your staff to discuss aspects of the program including the applicable regulatory commitments related to items such as regulations, regulatory guides, and industry standards. Additional information and documentation needed to support the inspection will be identified during the information gathering visit,.

The enclosure lists documents that are needed prior to the information gathering visit. Please provide the referenced information to the Region II Office by September 13, 2019. 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 October 18, 2019. During the information gathering visit, Dr. Greenleaf 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) licensee computer access, (4) working space, (5) arrangements for site access, and (6) other applicable information.

INFORMATION REQUEST FOR CATAWBA NUCLEAR STATION DESIGN BASES ASSURANCE INSPECTION (PROGRAMS)

(10 CFR 50.49 ENVIRONMENTAL QUALIFICATION PROGRAM IMPLEMENTATION)

Prior to the information gathering visit, please provide the information electronically in .pdf files, Excel, or other searchable format on CDROM (or FTP site, SharePoint, etc.). The CDROM (or website) should be indexed and hyperlinked to facilitate ease of use.
