Requalification Inspections
- Extra operator on dynamic scenarios
- Reactivation for Refueling
- Alternate Path JPMs
Extra Operator in Scenarios
§ 55.59 Requalification.
(a)(2)(ii) The operating test will require the operator or senior operator to demonstrate an understanding of and the ability to perform the actions necessary to accomplish a comprehensive sample of items specified in
§ 55.45(a) (2) through (13) inclusive to the extent applicable to the facility.
§ 55.45 Operating tests.
(a)(13) Demonstrate the applicant's ability to function within the control room team as appropriate to the assigned position, in such a way that the facility licensee's procedures are adhered to and that the limitations in its license and amendments are not violated.
Link to NRC Operator Licensing Feedback (IP.15):
https://www.nrc.gov/docs/ML2200/ML22004A209.pdf
Reactivation for Refueling NUREG-1021:
If a facility licensee needs to reactivate an SRO license as an LSRO (strictly for the purpose of supervising refueling activities), the operator must complete one shift under direction performing refueling activities, as discussed above, and the facility licensee must ensure that the operator is administratively restricted from performing full SRO duties.
NUREG-1262, Questions 253, 278, 287, and 289
Alt. Path JPMs - Common Challenges
- Directing the operator to perform an alternate path in the cue.
- The alternate path is expected based on cue or initial condition.
- Providing alt. path handouts at the beginning of the JPM
- Crediting Admin JPMs as Alt Path
Alt. Path JPM Goal
- OLPF 3.2.3 the goal is to assess the applicant's response to a situation that is not as it should be or is somehow different from what the applicant might have expected based on the initiating cue for the task.
Initial Examinations
