1 10 CFR Part 26 Subpart I Managing Fatigue Kamishan Martin Human Factors Engineering June 23, 2010 HPRCT conference

Overview Background / Purpose Rule Provisions Implementation Questions 2

3 Background NRC published GL 82-12, Policy on Worker Fatigue NRC issued IN 91-36, Nuclear Plant Staff Working Hours NRC staff reviewed adequacy of policy implementation Commission approved rulemaking Final Rule Published Licensees implemented measures for compliance

Background A degradation in a person’s cognitive and motor functioning resulting from inadequate rest. Acute Fatigue –fatigue from causes occurring in the past 24 hours, such as restricted sleep, sustained wakefulness and task demands. Cumulative Fatigue –increase in fatigue over consecutive sleep- wake periods resulting from inadequate rest.

Background Purpose: –Establishing clear and enforceable requirements for the management of worker fatigue to strengthen the effectiveness of FFD programs –Codify orders limiting security work hours –Strengthen the effectiveness of FFD programs at nuclear power plants 5

Rule Provisions Applicability Work Hour Controls Waivers and Exceptions Self Declarations Fatigue Assessments 6

Only to operating plants Fatigue management program elements apply to anyone with unescorted access Work hour limits, MDO requirements and rest break requirements in § apply subset of individuals referred to as “covered workers” 7 Applicability Rule Provisions Applicability

Maintenance Operations Chemistry Health Physics Fire Brigade Security Force Individuals who directs these activities 8 Applicability Rule Provisions Applicability

Work Hour Controls Rule Provisions Work Hour Controls Retain maximum work hour limits of: –16 hours in any 24-hour period –72 hours in any 7-day period Increase maximum work hour limits –24 to 26 hours in any 48-hour period Increase min. break period between work periods from 8 hours to 10 hours Limit waivers use conditions Added Minimum Days Off (MDO) requirements

Work Hour Controls Rule Provision Work Hour Controls MDO Requirements Vary According to: –Plant state (operating or outage) –Shift duration (8, 10, or 12 hours) –Job duties maintenance operations, health physics, chemistry, fire brigade security

Work Hour Controls Rule Provision Work Hour Controls MDO Requirements *Averaged over the shift cycle, from one to six weeks long. Days off must be distributed to provide at least 1 day off in any 9-day period

Outage Day off Requirements Periods are successive, not rolling Applies to every shift: 8, 10 or 12-hr Work Hour Controls Rule Provision Work Hour Controls

Waivers only allowed: –To mitigate or prevent a condition adverse to safety –To maintain the security of the facility Face-to-Face Fatigue assessment required to approve waiver Review of work hours + time of day work would be performed also considered in assessment Waivers Rule Provision Waivers

For-cause Post-event Follow-up Self-declaration Constraints on who can perform them –Trained –No conflicts of interest Fatigue Assessments Rule Provision Fatigue Assessments

A statement to your supervisor that you are not able to safely or competently perform your duties because of fatigue Self Declarations Rule Provision Self Declarations

16 Establishes recordkeeping requirements for licensees to retain specified records Requires licensees to report to the NRC certain data related to their fatigue management programs as part of the annual FFD program performance report Recordkeeping and Reporting Rule Provision Recordkeeping and Reporting

Rule Provision Performance Based –Licensees shall schedule the work hours of individuals who are subject to this section consistent with the objective of preventing impairment from fatigue due to the duration, frequency, or sequencing of successive shifts.
