SUBJECT:
COLUMBIA GENERATING STATION - NRC EXAMINATION REPORT 05000397/2021301
Dear Mr. Sawatzke:
On April 6, 2021, the U.S. Nuclear Regulatory Commission (NRC) completed an initial operator license examination at Columbia Generating Station. The enclosed report documents the examination results and licensing decisions. The preliminary examination results were discussed on February 26, 2021, with you and other members of your staff. A telephonic exit meeting was conducted on April 6, 2021, with Mr. C. Prost, Manager, Operations Training, who was provided the NRC licensing decisions.
The examination included the evaluation of four applicants for reactor operator licenses, six applicants for instant senior reactor operator licenses, and one applicant for upgrade senior reactor operator license. The license examiners determined that all applicants satisfied the requirements of 10 CFR Part 55, and the appropriate licenses have been issued. There was one post-examination comment 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.

SUMMARY
Examination Report 05000397/2021301; February 22 - April 6, 2021; Columbia Generating
Station; Initial Operator Licensing Examination Report
The NRC examiners evaluated the competency of four applicants for reactor operator licenses, six applicants for instant senior reactor operator licenses and one applicant for upgrade senior reactor operator license at Columbia Generating Station.
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 March 4, 2021. The NRC examiners administered the operating tests on February 22 - 26, 2021.
The NRC examiners determined that all 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 three 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 March 4, 2021, 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 and post-examination comments to the NRC on March 18, 2021.
The NRC examination team administered the various portions of the operating tests to all applicants from February 22 - 26, 2021.
b. Findings
No findings were identified.
All applicants passed the written examination and all parts of the operating test. 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 three generic weaknesses associated with applicant performance on the operating tests.
- Three of 4 crews did not correctly apply technical specifications after putting SPC into service.
- Three of 4 crews did not correctly identify a tripped contact.
- Eight of 11 individuals could not swap reactor building fans without getting a positive pressure in the building.
Post-examination analysis revealed four generic weaknesses associated with applicant performance on the written examination. These weaknesses were all associated with learning deficiencies.
- Question 19 - fire pump FP-P-1 automatically starts on a loss of control power when bus SH-5 is deenergized
- Question 41 - narrow range reactor pressure vessel level not density compensated
- Question 89 - actions associated with elevated battery room temperatures
- Question 92 - actions when wetwell level exceeds wetwell-to-drywell level limit
These weaknesses were captured in the licensees corrective action program as Action Request 00417260. 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
