SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 - INITIAL OPERATOR LICENSING EXAMINATION REPORT 05000277/2024301 AND 05000278/2024301

Dear David Rhoades:

On May 2, 2024, the U.S. Nuclear Regulatory Commission (NRC) completed an examination at the Peach Bottom facility. The enclosed examination report documents the examination results, which were discussed on May 30, 2024, with Ryan Stiltner, Plant Manager, and other members of your staff.

The examination included the evaluation of two applicants for reactor operator licenses and five applicants for instant senior reactor operator licenses. The facility licensee developed the written and operating examinations using NUREG-1021, Operator Licensing Examination Standards for Power Reactors, Revision 12. The license examiners determined all applicants satisfied the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 55, and the appropriate licenses were issued on May 30, 2024.

No findings were identified during this examination. This letter, its enclosure, and your response (if any) 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.

The written examination was administered by the facility on May 2, 2024. NRC examiners administered the operating tests April 22 - 26, 2024. The NRC examiners determined that all applicants satisfied the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 55, and the appropriate licenses have been issued.

REPORT DETAILS

4OA5 Other Activities (Initial Operator License Examination)

.1 License Applications

a. Scope

The examiners reviewed all license applications submitted by the licensee to ensure the applications reflected that each applicant satisfied relevant license eligibility requirements.

The applications were submitted on NRC Form 398, Personal Qualification Statement, and NRC Form 396, Certification of Medical Examination by Facility Licensee. The examiners also audited two of the license applications in detail to confirm that they accurately reflected the subject applicants qualifications. This audit focused on the applicants experience and on-the-job training, including control manipulations that provided significant reactivity changes.

b. Findings

No findings were identified.

.2 Operator Knowledge and Performance

a. Examination Scope

On May 2, 2024, the licensee proctored the administration of the written examinations to all applicants. The licensee staff graded the written examinations, analyzed the results, and presented their analysis to the NRC on May 20, 2024.

The NRC examination team administered various portions of the operating examination April 22 - 26, 2024. The applicants for a reactor operator license participated in at least two dynamic simulator scenarios, in a control room and facilities walkthrough test consisting of eleven system tasks, and an administrative test consisting of four administrative tasks. The applicants for instant senior reactor operator licenses participated in at least two dynamic simulator scenarios, a control room and facilities walkthrough test consisting of ten system tasks, and an administrative test consisting of five administrative tasks.

b. Findings

All applicants passed the operating test and the written examination. For the written examinations, the reactor operator applicants average score was 91.9 percent and ranged from 89.3 to 94.6 percent. The senior operator applicants average score was 91.8 percent and ranged from 87.0 to 97.0 percent. The text of the examination questions may be accessed in the ADAMS system under the accession numbers noted in the Attachment. In accordance with current NRC policy, the release of the written examination in ADAMS to the public will be delayed for two years.

Chapter ES-403 and Form ES-403-1 of NUREG 1021 require the licensee to analyze the validity of any written examination questions that were missed by half or more of the applicants. The licensee conducted this performance analysis and submitted the analysis to the chief examiner. The facility did not submit any post-exam comments.

.3 Initial Licensing Examination Development

a. Examination Scope

The facility licensee developed the examinations in accordance with NUREG-1021, Revision 12. All licensee facility training and operations staff involved in examination preparation and validation were listed on a security agreement. The NRC conducted an onsite validation of the operating examinations during the week of March 25, 2024.

b. Findings

No findings were identified. The examiners determined that the written and operating examinations initially submitted by the licensee were within the range of acceptability expected for a proposed examination.

.4 Simulation Facility Performance

a. Examination Scope

The examiners observed simulator performance with regard to plant fidelity during the examination validation and administration.

b. Findings

No findings were identified.

.5 Examination Security

a. Examination Scope

The examiners reviewed examination security for examination development during both the onsite preparation week and examination administration week for compliance with NUREG-1021, Revision 12, requirements. Plans for simulator security and applicant control were reviewed and discussed with licensee personnel.

b. Findings

No findings were identified.
