SUBJECT:

GRAND GULF NUCLEAR STATION - NRC EXAMINATION REPORT 05000416/2020302

Dear Mr. Franssen:

On November 19, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an initial operator license examination at Grand Gulf Nuclear Station. The enclosed report documents the examination results and licensing decisions. The preliminary examination results were discussed on October 22, 2020, with Mr. B. Wertz, General Manager Plant Operations, and other members of your staff. A telephonic exit meeting was conducted on November 19, 2020, with Mr. T. Tharp, Supervisor, Operations Training, who was provided the NRC licensing decisions.

The examination included the evaluation of five applicants for instant senior reactor operator licenses. The license examiners determined that three of the five applicants satisfied the requirements of 10 CFR Part 55, and the appropriate licenses have been issued. There were two post-examination comments submitted by your staff. Enclosure 1 contains details of this report and Enclosure 2 summarizes post-examination comment resolution.

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, Gregory E. Digitally signed by Gregory E.

Station, Unit 1; Initial Operator Licensing Examination Report The NRC examiners evaluated the competency of five applicants for instant senior reactor operator licenses at Grand Gulf Nuclear Station, Unit 1.

The licensee developed the examinations using NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 11. The written examination was administered by the licensee on October 26, 2020. The NRC examiners administered the operating tests on October 19-22, 2020.

The NRC examiners determined that three of the five applicants satisfied the requirements of 10 CFR Part 55, and the appropriate licenses have been issued.

NRC-Identified and Self-Revealing Findings

None.

Licensee-Identified Violations

None.

REPORT DETAILS

OTHER ACTIVITIES

- INITIAL LICENSE EXAM

.1 License Applications

a. Scope

The NRC examiners reviewed all license applications submitted to ensure each applicant satisfied relevant license eligibility requirements. The NRC examiners also audited one 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 Examination Development

a. Scope

The NRC examiners reviewed integrated examination outlines and draft examinations submitted by the licensee against the requirements of NUREG-1021. The NRC examiners conducted an onsite validation of the operating tests.

b. Findings

The NRC examiners provided outline, draft examination and post-validation comments to the licensee. The licensee satisfactorily completed comment resolution prior to examination administration.

The NRC examiners determined the written examinations and operating tests initially submitted by the licensee were within the range of acceptability expected for a proposed examination.

.3 Operator Knowledge and Performance

a. Scope

On October 26, 2020, the licensee proctored the administration of the written examinations to all five applicants. The licensee staff graded the written examinations, analyzed the results, and presented their analysis and post-examination comments to the NRC on November 5, 2020.

The NRC examination team administered the various portions of the operating tests to all applicants from October 19-22, 2020.

b. Findings

No findings were identified.

All applicants passed all parts of the operating test. Three out of five applicants passed the written examination. The final examinations and post-examination analysis and comments may be accessed in the ADAMS system under the accession numbers noted in the attachment.

The examination team noted no generic weaknesses associated with applicant performance on the operating test. Post examination analysis revealed nine generic weaknesses associated with applicant performance on the written examination:

• low pressure core spray injection pressure

• residual heat removal system procedure precautions and limitations

• direct current electrical bus alignment and procedures

• loss of power to the residual heat removal system while in containment spray mode of operation

• relief requirements for the at-the-controls operator

• restoration of the auxiliary building with elevated drywell temperature

• control room ventilation precautions and limitations

• event classification timing

• area access controlled by the on-shift senior reactor operator These weaknesses were captured in the licensees corrective action program as Condition Report CR-GGN-2020-11110. Copies of all individual examination reports were sent to the facility training manager for evaluation and determination of appropriate remedial training.

.4 Simulation Facility Performance

a. Scope

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

b. Findings

No findings were identified.

.5 Examination Security

a. Scope

The NRC examiners reviewed examination security for examination development during both the onsite preparation week and examination administration week for compliance with 10 CFR 55.49 and NUREG-1021. Plans for simulator security and applicant control were reviewed and discussed with licensee personnel.

b. Findings

No findings were identified.

EXIT MEETINGS AND DEBRIEFS
