SUBJECT:
DIABLO CANYON POWER PLANT, UNITS 1 AND 2 - NRC INITIAL
OPERATOR LICENSING EXAMINATION APPROVAL 05000275/2025301;
Dear Ms. Gerfen:
The purpose of this letter is to confirm the final arrangements for the upcoming operator
licensing examination at Diablo Canyon Nuclear Power Plant.
The NRC has completed its review of the operator license applications submitted in connection
with this examination and separately provided a list of approved applicants to Mr. K. Smith, NRC
Exam Development Lead. Note that any examination waivers and application denials have been
addressed in separate correspondence.
The NRC has approved the subject examination and hereby authorizes you to administer the
written examination in accordance with NUREG-1021, "Operator Licensing Examination
Standards for Power Reactors," Revision 12, on November 7, 2025. The NRC staff will
administer the operating tests during the week of October 27, 2025. This examination has
undergone extensive review by my staff and representatives responsible for licensed operator
training at your facility. Based on this review, I have concluded that the examination meets the
guidelines of NUREG-1021 for content, operational, and discrimination validity. By administering
this examination, you also agree that it meets NUREG-1021 guidelines and is appropriate for
measuring the qualifications of licensed operator applicants at your facility. If you determine that
this examination is not appropriate for licensing operators at your facility, do not administer the
examination and contact me at 817-200-1159.
