President and Chief Nuclear Officer

SUBJECT:

HOPE CREEK NUCLEAR GENERATING STATION - INFORMATION

REQUEST FOR TRIENNIAL BASELINE DESIGN BASES ASSURANCE

INSPECTION (TEAM); NOTIFICATION TO PERFORM INSPECTION

05000354/2021010

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 Design Bases Assurance Inspection (DBAI) at your Hope Creek

Nuclear Generating Station. 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, Design Bases Assurance Inspection (Team), dated

December 8, 2016 (ADAMS Accession No. ML16340B000).

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 conversation on February 8, 2021, with Mr. Francis Possesski, 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 June 7th, 2021.

Onsite weeks: Weeks of August 2, 2021 and August 16, 2021.

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.

Frank Arner, a Region I Senior Risk Analyst, will support Jeff Kulp 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

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 May 17, 2021. By July 2,

2021, the lead inspector will communicate the initial selected set of components and

modifications.

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 July 26, 2021. 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 Tom Cachaza or Tina Gregory.

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 Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Information Requested for Selection of Components and Modifications

The following information is requested by May 17, 2021, to facilitate inspection preparation.

Feel free to contact the lead inspector as soon as possible if you have any questions

regarding this information request. Please provide the information electronically in pdf

files, Excel, or other searchable formats, preferably on some portable electronic media (e.g.,

CD-ROM, DVD). 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.

Include values for Risk Reduction Worth, Birnbaum Importance, and Fussell-Vesely (as

applicable). Please provide in an excel spreadsheet or other sortable format, and

include an understandable definition of the coded basic events.

3.

Risk-ranking of top 100 components from site specific PRA sorted by Large Early

Release Frequency. Provide any basic event mapping used to develop the ranking of

components.

4.

List of the top 200 cut-sets from your PRA. Provide the descriptions of the basic events

in the list of cut-sets.

5.

List of the top 200 cut-sets for each initiator modeled in the PRA that contributes more

than 5 percent to the baseline plant core damage frequency.

6.

If you have an External Events or Fire PRA Model, provide the information requested in

Items 1 and 2 for external events and fire. Provide narrative description of each coded

event, including fire and flood zone description.

7.

List of time-critical and/or risk significant operator actions.
