SUBJECT: SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2 - INFORMATION

REQUEST FOR QUADRENNIAL BASELINE COMPREHENSIVE

ENGINEERING TEAM INSPECTION; NOTIFICATION TO PERFORM

INSPECTION 05000272/2023011 AND 05000311/2023011

Dear Eric Carr:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

Region I staff will conduct a Comprehensive Engineering Team Inspection (CETI) at your Salem

Nuclear Generating Station, Units 1 and 2. Jeffrey Kulp, a Senior Reactor Inspector from the

NRCs Region I office, will lead the inspection team. The inspection will be conducted in

accordance with Inspection Procedure 71111.21M, Comprehensive Engineering Team

Inspection (CETI), dated January 1, 2023 (ADAMS Accession No. ML19084A030). This

inspection combines elements of the Design Basis Assurance Inspection (Teams), the Heat

Exchanger/Sink Performance inspection (71111.07T), and the Evaluations of Changes, Tests

and Experiments inspection (71111.17).

The inspection will evaluate the capability of risk-significant/low-margin components to function

as designed to support proper system operation. The inspection will also include a review of

selected modifications, operating experience, and as applicable, operator actions.

During a telephone conversation on October 26, 2022, with Harry Balian and Bernadette Cizin,

Salem/Hope Creek Regulatory Compliance, we confirmed arrangements for an information-

gathering site visit and the two-week onsite inspection. The schedule is as follows:

• Information-gathering visit: Week of December 12, 2022

• Onsite weeks: Weeks of January 23, 2023 and February 6, 2023

The purpose of the information-gathering visit is to meet with members of your staff to identify

risk-significant components, modifications, operator actions, and operating experience items.

Information and documentation needed to support the inspection will also be identified.

Carey Bickett, a Region I Senior Risk Analyst, will support Jeff during the information-gathering

visit to review probabilistic risk assessment data and identify components to be examined during

the inspection.

Experience with previous baseline design/modification inspections of similar depth and length

has shown this type of inspection is resource intensive, both for the NRC inspectors and the

licensee staff. In order to minimize the inspection impact on the site and to ensure a productive

E. Carr 2

inspection for both parties, we have enclosed a request for information needed for the

inspection.

It is important that all of these documents are up-to-date and complete in order to minimize the

number of additional documents requested during the preparation and/or the onsite portions of

the inspection. Insofar as possible, this information should be provided electronically to the lead

inspector. The information request has been divided into two groups:

• The first group lists information necessary for our initial inspection scoping activities.

This information should be provided to the lead inspector by December 5, 2022. By

December 23, 2022, the lead inspector will communicate the initial selected set of

components, modifications, 50.59 screenings, and operating experience samples.

• The second group of documents requested is those items needed to support our in-

office preparation activities. This set of documents, specific to the selected components

and modifications, should be provided to the lead inspector at the Regional Office no

later than January 16, 2023. During the in-office preparation activities, the team may

identify additional information needed to support the inspection, and those items will be

communicated directly to Harry Balian or Bernadette Cizin.

If there are any questions about the inspection or the material requested in the enclosure,

please contact the lead inspector at (610) 547-2603 or via email at jak2@nrc.gov.

This letter does not contain new or amended information collection requirements subject to the

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection

requirements were approved by the Office of Management and Budget, Control Number 3150-

0011. The NRC may not conduct or sponsor, and a person is not required to respond to, a

request for information or an information collection requirement unless the requesting document

displays a currently valid Office of Management and Budget Control Number.

This letter and its enclosure 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 Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Sincerely,
