SUBJECT:
DIABLO CANYON POWER PLANT, UNITS 1 AND 2 - NOTIFICATION OF COMMERCIAL GRADE DEDICATION INSPECTION (05000275/2023010 AND 05000323/2023010) AND REQUEST FOR INFORMATION
Dear Paula A. Gerfen:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff will conduct the commercial grade dedication baseline inspection at Diablo Canyon Power Plant, Units 1 and 2, beginning on March 27, 2023. The inspection team will be composed of three personnel from the NRC Region IV office. The inspection will be conducted in accordance with NRC inspection procedure (IP) 71111.21N.03, Commercial Grade Dedication, dated June 28, 2022.
The inspection will evaluate the implementation of Diablo Canyon Power Plants process for dedicating commercial-grade items, as required in applicable portions of Appendix B to Title 10 of the Code of Federal Regulations Part 50, to ensure reasonable assurance is provided that these items will perform their intended safety function. Additionally, this inspection will evaluate implementation of Diablo Canyon Power Plants procurement process for safety-related structures, systems, and components, as required in Appendix B.
The inspection will include an onsite information gathering visit by the team lead and two weeks of onsite inspection by the team. The schedule for the inspection is as follows:
Onsite Information Gathering Visit: February 27 - March 2, 2023
Offsite Preparation Week: March 20 - 24, 2023
Onsite Inspection Weeks: March 27 - 30, 2023, and April 10 - 13, 2023 The purpose of the information gathering visit is to meet with your staff to become familiar with the process for dedicating commercial-grade items and the process for procuring safety-related structures, systems, and components at Diablo Canyon Power Plant. This visit may include a tour of onsite commercial-grade item dedication facilities, receipt inspection facilities, storage facilities, and installed plant components associated with potential inspection samples. During the visit, the team lead will also review the information provided in the initial information request
P. Gerfen 2
to select a list of potential inspection samples. The team lead may also identify other information needed to support the inspection during this visit.
To minimize the impact on your staff and to ensure an effective and efficient inspection, we have enclosed two separate requests for information needed prior to the onsite information gathering visit and offsite inspection preparation week. The first request (Enclosure 1) is generally for information that will be used to choose the inspection samples or information that will be applicable to all inspection samples throughout the inspection. This information should be made available to the team lead prior to the information gathering visit. The second request (Enclosure 2) is for information that is specific to an individual sample and should be made available prior to the offsite preparation week.
Additional information requests, interviews with your staff, and/or walkdowns of facilities or installed plant components will be made by the team throughout the inspection to complete their review of the selected inspection samples. It is important that all documentation provided to the team is complete and up-to-date to minimize the number of additional documents requested during the preparation and/or the onsite portions of the inspection. Additionally, to facilitate an efficient inspection, we request that a contact individual be assigned to each inspector to ensure information requests, questions, and concerns are addressed in a timely manner.
We understand that Mr. Dave Madsen from your Regulatory Affairs organization is our contact for this inspection. If there are any questions about the inspection or the information requested, please contact the team lead, Mr. Wes Cullum, by telephone at 817-200-1563 or by e-mail at wes.cullum@nrc.gov. Enclosure 3 contains additional contact information for the inspection team.
