Fatigue Waiver
A fatigue waiver is a part of the fatigue management program which allows an individual to exceed work hour limits.
Valid Justifications for Waivers
A waiver should only be used to correct a condition adverse to safety or security.
Conditions Adverse to Safety include:
- Public or station personnel health or safety is jeopardized.
- Recovery from a challenge to the safety function of a system or component is delayed.
- Compliance with another NRC regulatory requirement is impaired or prevented.
- Mitigation of a Technical Specification required reactor shutdown or power reduction is impaired or prevented.
- Unplanned increase in the plant status risk color assignment.
- Compliance with site environmental permits is impaired or prevented.
- External events (weather, fire, flooding) pose a risk to station personnel.
To the extent practicable, licensees shall rely upon the granting of waivers only to address circumstances that could not have been reasonably controlled.
Counting Waivers
Multiple work hour requirements may be waived for an individual to perform covered work during any single work period. One Waiver Form may be used to document the waiving of one or more work hour requirement(s) for any single work period or for multiple work periods. For reporting purposes, each work hour requirement that is waived in a work period constitutes one waiver, in accordance with 10 CFR 26.203(e)(1).[1]
