SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION, UNITS 2 AND 3 - INITIAL OPERATOR LICENSING EXAMINATION REPORT 05000277/2022301 AND 05000278/2022301

Dear David Rhoades:

On June 2, 2022, 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 June 27, 2022, with D. Henry, Site Vice President, and other members of your staff.

The examination included the evaluation of one applicant for a reactor operator license, five applicants for instant senior reactor operator licenses, and one applicant for an upgrade senior reactor operator license. The written and operating examinations were developed 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 June 27, 2022.

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.

Sincerely, Donald E. Jackson, Chief Operations Branch Division of Operating Reactor Safety

SUMMARY

ER 05000277/2022301 and 05000278/2022301; May 23-June 2, 2022; Peach Bottom Atomic

Power Station, Units 2 and 3; Initial Operator Licensing Examination Report.

Four NRC examiners evaluated the competency of one applicant for a reactor operator license, five applicants for instant senior reactor operator licenses, and one applicant for an upgrade senior reactor operator license. The facility licensee developed the examinations using NUREG-1021, Operator Licensing Examination Standards for Power Reactors, Revision 12. The written examination was administered by the facility on June 2, 2022. NRC examiners administered the operating tests May 23-26, 2022. 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.

NRC-Identified and Self-Revealing Findings

No findings were identified.

Licensee-Identified Violations

None.

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 the license applications 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 June 2, 2022, 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 June 20, 2022.

The NRC examination team administered various portions of the operating examination May 23-26, 2022. The applicant 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. The applicant for an upgrade senior reactor operator license participated in at least one dynamic simulator scenario, a control room and facilities walkthrough test consisting of five system tasks, and an administrative test consisting of five administrative tasks.

b. Findings

No findings were identified.

All applicants passed the operating test and the written examination. For the written examinations, the reactor operator applicants score was 97.3 percent. The senior operator applicants average score was 90.5 percent and ranged from 86.0 to 93.0 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.

Additionally, post-examination review revealed several questions that were missed by more than 50 percent of the applicants. Reactor Operator question 44 was missed by 57 percent, Reactor Operator question 50 was missed by 57 percent, Senior Reactor Operator question 7 was missed by 50 percent, Senior Reactor Operator question 11 was missed by 50 percent, and Senior Reactor Operator question 19 was missed by 100 percent of the applicants, respectively. A review of these questions determined that no flaws existed with the questions themselves, and the issue was the applicants respective knowledge of the question topics.

Chapter ES-4.4 of NUREG-1021 requires the licensee to review and resolve any questions and comments that arose during or after the examination. The licensee conducted this review and submitted it to the Chief Examiner.

.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 facility licensee submitted the operating examination outline on December 23, 2021. The Chief Examiner reviewed the outlines against the requirements of NUREG-1021 and provided comments to the licensee. The facility licensee submitted the draft examination package on March 28, 2022. The Chief Examiner reviewed the draft examination package against the requirements of NUREG-1021 and provided comments to the licensee on the examination. The NRC conducted an onsite validation of the operating examinations and provided further comments during the week of April 25, 2022. The licensee satisfactorily completed comment resolution on May 11, 2022.

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 and 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.

4OA6 Meetings, Including Exit

The Chief Examiner presented the examination results to D. Henry, Site Vice President, and other members of the licensee's staff on June 27, 2022.
