Dear Mr. Powell:
On July 20, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an initial operator license examination at South Texas Project, Units 1 and 2. The enclosed report documents the examination results and licensing decisions. The preliminary examination results were discussed on July 24, 2020, with Mr. Schaefer, Site Vice President, and other members of your staff. A telephonic exit meeting was conducted on September 24, 2020, with Mr. W. Markham, License Training Instructor, who was provided the NRC licensing decisions.
The examination included the evaluation of 5 applicants for reactor operator licenses, 8 applicants for instant senior reactor operator licenses, and 3 applicants for upgrade senior reactor operator licenses. The license examiners determined that 11 of the 16 applicants satisfied the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 55 and the appropriate licenses have been issued. There were 3 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.

b. Findings
No findings were identified.
All applicants passed all parts of the operating test and 11 of 16 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 six generic weaknesses associated with applicant performance on the operating tests. These are listed below:
1) Eleven of sixteen applicants missed a subcooling margin administrative job performance measure. The equation to do the calculation is not in the procedure. It is considered skill of the craft by licensee.
2) Two of four crews struggled with recognition/diagnosis of a dropped rod event during a scenario.
3) Two of four crews struggled with recognition/diagnosis of an ejected rod during a scenario.
4) Four of four crews were slow to diagnose a steam leak with a steam generator tube rupture during a scenario.
5) Three of four crews attempted to close the emergency diesel generator output breaker to re-energize an isolated and locked out bus during a scenario.
6) Two of three crews struggled to diagnose recirculation valve performance during a charging pump shaft shear event during a scenario.
The licensee generated Condition Reports CR 20-7873 and CR 20-8347 to address these operating test performance generic weaknesses.
Post-examination analysis revealed eight generic weaknesses associated with applicant performance on the written examination. These are discussed below:
1) Q12 - 56 percent missed it due to applicant knowledge weakness and the topic was valves that receive a phase A signal or safety injection signal 2) Q20 - 50 percent missed it due to applicant knowledge weakness and the topic was the master relay defeat switch 3) Q46 - 63 percent missed it due to applicant knowledge weakness and the topic was loss of instrument air effects on charging 4) Q69 - 50 percent missed it due to applicant knowledge weakness and the topic was entry conditions for technical specifications for refueling water storage tank level 5) Q74 - 50 percent missed it due to applicant knowledge weakness and the topic was design requirements of auxiliary feedwater 6) Q81 - 64 percent missed it due to applicant knowledge weakness and the topic was key control for locked high radiation areas (technical specifications)7) Q90 - 64 percent missed it due to applicant knowledge weakness and the topic was inoperable offsite sources during grid disturbance (technical specifications)8) Q100 - 73 percent missed it due to applicant knowledge weakness and the topic was in-service testing requirements The licensee generated Condition Report CR 20-8347 to address these written examination performance generic weaknesses. Copies of all individual examination reports were sent to the facility training manager for evaluation and determination of appropriate remedial training. Additionally, there were 3 post examination comments submitted by the licensee and they are discussed briefly in Enclosure 2. There is also a complete text of the licensee's post-examination analysis and comments located in ADAMS under Accession Number ML20282A517.
.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. However, there were a few malfunctions used in the scenarios that contained erroneous failures that were not seen during validation. These issues were all evaluated with Condition Report CR-20-7888.
.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.
Findings Four exam security issues were identified by the licensee and were all assessed as minor. Corrective actions to restore compliance are complete and no exam compromises occurred. The corrective actions include Condition Reports CR 19-13973, CR 20-5960, CR 20-6293, and CR-20-6295.
