SUBJECT:
DIABLO CANYON POWER PLANT, UNITS 1 AND 2 - NRC EXAMINAT ION REPORT 05000275/2020301 AND 05000323/2020301
Dear Mr. Welsch:
On March 24, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an initial operator license examination at your Diablo Canyon Power Plant, Units 1 and 2. The enclosed report documents the examination results and licensing decisions. The preliminary examination results were discussed on February 27, 2020, with Ms. P. Gerfen, Site Vice President, and other members of your staff. A telephonic exit meeting was conducted on March 24, 2020, with Mr. A. Kadir, Exam Supervisor, who was provided the NRC licensing decisions.
The examination included the evaluation of six applicants for reactor operator licenses, seven 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 were no post-examination comments submitted by your staff. The enclosure contains details of this report.
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
ER 05000275/2020301; 05000323/2020301, 02/24/2020 - 03/24/2020, Diablo Canyon Power
Plant, Units 1 and 2, Initial Operator Licensing Examination Report The NRC examiners evaluated the competency of six applicants for reactor operator licenses, seven applicants for instant senior reactor operator licenses, and one applicant for upgrade senior reactor operator license at Diablo Canyon Power Plant, Units 1 and 2.
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 6, 2020. The NRC examiners administered the operating tests from February 24 - 28, 2020.
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

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 6, 2020, 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 March 22, 2020.
The NRC examination team administered the various portions of the operating tests to all applicants from February 24 - 28, 2020.
b. Findings
No findings were identified.
All applicants passed the written examination and all parts of the operating tests. The final written examinations and post-examination analysis may be accessed in the ADAMS system under the accession numbers noted in the attachment. There were no post-examination comments as indicated in the licensee submittal.
The examination team noted no generic weaknesses associated with applicant performance on the operating tests. The licensee identified three generic weaknesses associated with applicant performance on the written examinations:
