Mr. Eric Carr

President and Chief Nuclear Officer

PSEG Nuclear, LC - N09

P.O. Box 236

Hancocks Bridge, NJ 08038

SUBJECT: HOPE CREEK GENERATING STATION - INFORMATION REQUEST TO

SUPPORT DESIGN-BASIS CAPABILITY OF POWER-OPERATED VALVES

INSPECTION; INSPECTION REPORT 05000354/2022012

Dear Mr. Carr:

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

Region I staff will conduct a team inspection at Hope Creek Generating Station. Mr. Jeff 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 71111.21N.02, Design-

Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements, dated

October 9, 2020 (ADAMS Accession No. ML20220A667).

The inspection will assess the reliability, functional capability, and design bases of risk-important

power-operated valves (POVs) as required by Title 10 of the Code of Federal Regulations

(10 CFR) 50.55a, and Appendix A and B requirements. The inspectors will select a sample of

POVs based on risk insights, safety significance, and operating margin.

During a telephone conversation on February 11, 2022, with Mr. Harry Balian, Compliance

Specialist, we confirmed arrangements for an information gathering visit and the two-week

onsite inspection. Depending on site access conditions, the information gathering visit may be

onsite or may be performed remotely. The schedule is as follows:

  • Information gathering visit: Week of May 2, 2022
  • Onsite weeks: Weeks of July 11 and July 25, 2022

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

become familiar with your programs and procedures intended to ensure compliance with 10 CFR 50.55a for POVs. The lead inspector will discuss aspects of the programs including any

specific applicable regulatory commitments made by your facility and your use of NRC

regulatory guides or industry standards.

E. Carr 2

Experience with previous design basis team inspections of similar depth and length has shown

this type of inspection is resource intensive, both for NRC inspectors and licensee staff. In

order to minimize the inspection impact on the site and to ensure a productive inspection for

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

provided an advance copy of the request for information to Mr. Balian earlier this year.

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

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

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

inspector at the NRC Region I Office by May 2, 2022. Recognizing the timeframe, my staff will

work with your staff to prioritize our document requests so these activities can be accomplished,

as much as possible, in the normal course of your activities. Additional documents may be

requested during the information gathering visit and/or during team preparation week (the week

prior to the first onsite inspection week). The inspectors will minimize your administrative

burden by specifically identifying only those documents required for the inspection.

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

please contact the lead inspector at 610-337-5348 or via e-mail 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 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

I. Information Gathering Visit

During this visit, we plan to obtain sufficient insights to finalize power-operated valve (POV)

samples for this inspection. We would like to meet with POV specialists to discuss the

upcoming inspection and our sample selection process. The primary valve types to be

reviewed for this inspection include motor-operated valves (MOVs) and air-operated valves

(AOVs); and additional valve types include hydraulic-operated valves (HOVs), solenoid-

operated valves (SOVs), and pyrotechnic-actuated (squib) valves. During this visit, the lead

inspector will: (a) discuss the scope of the planned inspection; (b) identify additional

information needed to review in preparation for the inspection; (c) ensure that the

information to be reviewed is available at the beginning of the inspection; and (d) verify that

logistical issues will be identified and addressed prior to the teams arrival. Depending on

the local COVID environment and potential travel restrictions, this visit may be either onsite

and/or performed remotely through a series of video calls. If performed onsite, please

reserve a room during the site visit with a telephone, wireless internet access, and a

licensee computer with access to procedures, corrective action program documents, and a

printer.

II. Information Requested for Selection of Power-Operated Valves

The following information is requested to facilitate inspection preparation. Feel free to

contact the lead inspector if you have any questions regarding this information request.

Please provide the information electronically in pdf files, Excel, or other searchable

formats. The files should contain descriptive names, and be indexed and hyperlinked to

facilitate ease of use. Information in lists should contain enough information to be easily

understood by someone who has knowledge of light water reactor technology and POVs.

1. A word-searchable Updated Final Safety Analysis Report. If not available in a single file

for each unit, please ensure a collective table of contents is provided.

2. Site (and corporate if applicable) procedures associated with implementation of the MOV

program required by 10 CFR 50.55a(b)(3)(ii) and/or ASME OM Code Mandatory
