Work hour controls do not apply to the following individuals and activities:
Maintenance, as defined per Part 26, does not include activities that have not historically been defined as maintenance, that are non-intrusive, and pose low risk to the health and safety of the public, such as calculations, non-destructive analysis (NDE), thermography, vibration analysis, data collection and analysis.
Note: At times an activity requires starting or stopping a piece of equipment. The worker starting or stopping the equipment would be performing covered work under the operating category; however, the data collection activity would not be considered a covered work activity.

Although the guidance in schedule. They stated, NRCs guidance in DG-0526 would Section 7.1 of NEI 06-11, Revision 1, describes a quarterly implement a running average of hours worked during a work review process to address this concern, the NRC staff does cycle to calculate minimum days off for that work cycle. not consider implementation of that process as meeting the This method could have unintended consequences on the requirements of the rule. Specifically, the process would continuity of supervision and emergent work activities. allow work hours for emergent work to be excluded from The commenters argued that the revisions to NEI 06-11, consideration in the determination of the applicable MDO Revision 1, will address NRCs concerns with the excessive requirements. In addition, by allowing deviations from the use of periodic overtime and will provide transparency to the MDO requirements to be controlled through quarterly regulator through the corrective action program. reviews, the process would circumvent the waiver requirements in 10 CFR 26.207, Waivers and Exceptions.
Industry Recommendation:
The NRC is requested to endorse the guidance provided in The MDO requirements in 10 CFR 26.205(d)(3) are NEI 06-11, Managing Personnel Fatigue at Nuclear Power designed to prevent cumulative fatigue while Reactor Sites, Revision 1, Section 7.1, Periodic Overtime. accommodating variations in workload that result from emergent work. For example, the MDO requirements for maintenance personnel on 8- and 10-hour shifts allow, on average, an extra day of work per week above a nominal 40-hour workweek. The MDO requirements for maintenance on 12-hour shifts allow, on average, an extra 1.5 days per week. In addition, the requirements allow licensees to meet the MDO requirements as an average over a period of up to 6 weeks. As a result, licensees have the flexibility to distribute these extra workdays as necessary to accommodate emergent work. As noted in the FR notice for the final rule (73 FR 16988; March 31, 2008),
10 CFR 26.205(d)(3) accommodates a wide range of scheduling practices and short-term fluctuations in workload. Because the requirement was intended to Appendix B to RG 5.73, Page B-5
Response to Public Comments on Draft Regulatory Guide DG-5026 (RG 5.73),
Fatigue Management for Nuclear Power Plant Personnel New Regulatory Guide 5.73 Comment from Comment NRC Staff Disposition accommodate fluctuations in workload within limits that prevent cumulative fatigue, the NRC staff does not endorse the guidance in Section 7.1 of NEI 06-11, Revision 1, which would permit these limits to be exceeded through the exclusion of work hours for emergent work.
As stated in 10 CFR 26.205(d)(3), Licensees shall ensure that individuals have, at a minimum, the number of days off specified in this paragraph. The staff considers the appropriate means of deviating from this requirement to be the waiver process described in 10 CFR 26.207. In this regard, the staff notes that the rule permits licensees to grant waivers of the work-hour controls in 10 CFR 26.205(d)(1) through 10 CFR 26.205(d)(5)(i), including the MDO requirements of 10 CFR 26.205(d)(3). The waiver requirements in 10 CFR 26.207 are intended to ensure that deviations from the work-hour controls, including the MDO requirements, are limited to circumstances necessary to prevent or mitigate conditions adverse to safety or security.
By allowing deviations from the MDO requirements to be controlled through quarterly reviews, and by using criteria unrelated to safety or security, the process described in NEI 06-11, Revision 1, will circumvent the rules waiver requirements.
In accordance with the staffs view that the guidance contained in NEI 06-11, Revision 1, does not provide an acceptable means to comply with the regulation, Regulatory Positions 4, 5 and 6 in the final regulatory guide revise the guidance that depends on the concept of periodic overtime. Regulatory Position 4 revises a paragraph in Section 7, Work Hours Scheduling, of NEI 03-11, Revision 1, which discusses periodic overtime. The staffs Appendix B to RG 5.73, Page B-6

Regulatory Position 6 in the final regulatory guide presents guidance the staff finds acceptable for managing work-hours transitions during a shift cycle.
3 NEI and Regulatory Position 3Shifts of More Than 11 Hours The NRC staff agrees that NEI 06-11, Revision 1, supporters incorporates the additional language recommended by the The commenters stated, This position is incorporated into staff to address average shift durations of more than NEI 06-11, Managing Personnel Fatigue at Nuclear Power 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> per day. Therefore, the final regulatory guide Reactor Sites, Revision 1. retains the guidance NEI added in NEI 06-11, Revision 1, in Regulatory Position 5.
Industry Recommendation:
Revise DG-5026 to endorse NEI 06-11, Revision 1, and eliminate this position.
4 NEI and Regulatory Position 4Transitions The NRC staff considers Section 7.3, Transitioning onto a supporters Shift or Between Covered Groups or into a Covered The commenters stated, This position has been incorporated Group, of NEI 06-11, Revision 1, to be acceptable, except into NEI 06-11, Managing Personnel Fatigue at Nuclear for the last bullet that reads, A minimum of 2 days off in Power Reactor Sites, Revision 1. the preceding 7-day period is acceptable for operators who have been working outage hours on 10- or 12-hour shifts Industry Recommendation: before they transition to the non-outage unit as one of the Revise DG-5026 to endorse NEI 06-11, Revision 1, and two required operators working non-outage minimum days eliminate this position. off. This does not preclude short-term relief of the non-outage unit operators as described in Section 8.3. For the reasons discussed with respect to Comment 6 in this table, the staff does not agree that only two operators on an operating unit should remain on nonoutage work hours at a multiunit site with one or more units in an outage.
Therefore, Regulatory Position 7 in the final regulatory guide clarifies the last bullet before the examples in that section as follows:

Response to Public Comments on Draft Regulatory Guide DG-5026 (RG 5.73),
Fatigue Management for Nuclear Power Plant Personnel New Regulatory Guide 5.73 Comment from Comment NRC Staff Disposition A minimum of 2 days off in the preceding 7-day period is acceptable for operators at a multiunit site with one or more units in an outage, if the operators have been working outage hours on 10- or 12-hour shifts before they transition to an operating unit as members of the minimum shift complement described in Section 8.3.

However, the The commenters stated, The industry requests that the staff staffs position remains that, at a minimum, those reconsiders their position on eligibility for outage minimum individuals who constitute the operator minimum shift days off and endorses a requirement that a minimum of one complement, including the operator at the controls and the reactor operator and one senior reactor operator for each senior operator in the control room, as specified in operating reactor at a multi-unit station will not be eligible 10 CFR 50.54, Conditions of Licenses, for the operating for outage minimum days off.

Licensee employees and contractor/vendor personnel may go from an outage at one site to an outage at another site.
When a licensee employee or contractor/vendor performs covered work for a licensee during two or more unit outages or security system outages (or a combination thereof), and the interval(s) between successive outages is less than 9 days, the receiving licensee should determine that the individual has had a 34-hour break period within the 9 days that precede the day on which the individual begins working for the receiving licensee. In addition, when the individual begins work for the receiving licensee, the licensee should ensure that the individuals hours worked did not and will not exceed the following limits:
- 1. 16 work hours in any 24-hour period
- 2. 26 work hours in any 48-hour period
- 3. 72 work hours in any 7-day period For individuals (either employees of a licensee or a C/V) who transition between sites under other circumstances, the NRC staff expects that the appropriate implementation guidance contained in Section 7.3 of NEI 06-11, Revision 1, would apply.

15 IBEW Reporting Fatigue-Related Concerns The correct method for reporting fatigue concerns depends on the type of concern and the reporting procedures the Reference in NEI 06-11: licensee has established. If an individual is concerned that Being aware of the total hours worked in the previous 14 he or she is not fit to safely and competently perform his or days and notifying management if work hour limits will be her duties for any part of a working tour as a result of exceeded if asked to work additional hours. fatigue, the individual should follow the self-declaration procedures that licensees are required to establish under IBEW Comment 5: 10 CFR 26.203(b)(1). If an individual is concerned that a Are fatigue concerns appropriate to document in a Behavior coworker may not be fit to safely and competently perform Observation Program (BOP)? Is it the correct vehicle? duties as a result of fatigue (or any other cause),
10 CFR 26.33, Behavioral Observation, requires the individual to report the concern to the personnel designated in the licensees FFD policy.
10 CFR 26.29(a)(10) requires licensees to train personnel on the procedures to follow to make a self-declaration of fatigue and to report a fitness concern about a coworker. 10 CFR 26.29(a)(10) also requires licensees to ensure that individuals have the ability to initiate the appropriate actions if an individual has a concern.
Concerns regarding licensee implementation of the fatigue management requirements of 10 CFR Part 26 should be reported and addressed through the licensees process(es) for the identification and resolution of safety concerns or may be reported directly to the NRC through its allegations process.
16 IBEW Work-Hours Tracking Tool for Individuals Although 10 CFR Part 26 does not impose a requirement on individuals to track their work hours and days off, the NRC Reference in NEI 06-11: staff has not taken an exception to the guidance in Appendix B to RG 5.73, Page B-18

However, Work hours controls do not apply to the following individuals 10 CFR Part 26 does not currently require that individuals and activities: who are solely performing QC activities, without also

This presents a detailed knowledge of the tasks to be performed by the double standard in the rule if escorted C/Vs are not required individual working under a waiver. Because the activity of to have qualified individuals overseeing the work of the C/V escorting a C/V and conducting a supervisory assessment on risk significant SSCs. are fundamentally different, the NRC staff does not agree that the rule presents a double standard.

This sentence should be removed.
The staff also agrees with the portion of this comment that suggests that onsite study time required by the licensee should be considered work hours for the purposes of calculating the maximum work hours permissible and the MDO requirements for covered workers under 10 CFR 26.205. After-hours self-study required by the licensee should also be considered work hours for calculation purposes, as discussed in the SOC for 10 CFR 26.205(d)(2).
Neither training nor required study time is covered work, however. The hours spent in training or required study by a worker who otherwise performs covered duties should be included in the calculation of the individuals work hours only if the individual participates in training or required study during a shift cycle that also includes hours worked Appendix B to RG 5.73, Page B-23

If an individual voluntarily dedicates after-hours personal time to study that is not required by the licensee, those voluntary study hours should not be considered hours worked for the purposes of calculating work hours and the MDO requirements for covered workers under the rule. As defined in 10 CFR 26.205(b), work hours are the amount of time the individuals perform duties for the licensee.
Voluntary after-hours study time does not meet this criterion. Therefore, because the sentence referenced by the commenter discusses after-hours study time that is not required by the licensee and does not conflict with the requirements for calculating work hours in 10 CFR 26.205(b)(3), the staff is not clarifying this implementation guidance in the final regulatory guide.
24 IBEW Work Performed at Home for the Licensee 10 CFR 26.205(b) requires licensees to include, in the calculation of an individuals work hours, the amount of Reference in NEI 06-11: time the individual performs duties for the licensee.

We predict that the regulations will have the unintended effect of producing chronic low nuclear-returnee rates, by experienced construction workers when employment in that industry becomes a third or fourth-choice option in light of other opportunities in a booming industrial construction marketplace. As a result, nuclear contractors will likely experience a lack of available skilled labor during outages at nuclear power plants, resulting in the potential for unintended consequences such as higher rates of work-related injuries, reduced work quality and longer outage durations.

A smaller subset of workers who are granted unescorted access to the protected areas of a nuclear power reactor also are subject to the work-hour controls in 10 CFR 26.205 if they perform one of the covered duties specified in 10 CFR 26.4(a)(1) through 10 CFR 26.4(a)(5). One of these covered duties is maintenance or onsite direction of the maintenance of SSCs that a risk-informed evaluation process has shown to be significant to public health and safety. Construction workers who perform such duties and who have been granted unescorted access will be covered by the work-hour controls.

Fatigue Management for Nuclear Power Plant Personnel New Regulatory Guide 5.73 Comment from Comment NRC Staff Disposition However, with respect to any of the temporary full-time outage workers mentioned in the comment who may be affected (i.e., based on their duties and access status), it is worth noting that the NRC considered the issues raised by the comment when developing the final rule and included adjustments allowing longer work hours for individuals performing covered maintenance activities. The most notable adjustment (given the issues raised in this comment) is that 10 CFR 26.205(d)(4) relaxes the MDO requirements for individuals performing covered maintenance during the first 60 days of an outage, to a minimum of 1 day off in any 7-day period. As a result of these adjustments, the NRC staff believes that the concerns raised by the commenter have been greatly reduced.
Because the commenters exemption request seeks to exempt an entire class of individuals from the 10 CFR Part 26 fatigue management requirements, the commenter is essentially requesting that the NRC revise the 10 CFR Part 26 requirements as they apply to these individuals. Such a request is more appropriately submitted through a petition for rulemaking under 10 CFR 2.802, Petition for Rulemaking.

- Workers on the operating reactor at the time of the accident admitted to being too fatigued to perform assigned tasks (NUREG-0600).
- Since the Three Mile Island accident, the NRC has been concerned about fatigue impairing workers performance and its detrimental effects on nuclear plant safety (NRC Circular No. 80-02).

2008 letter enforcement discretion for the fatigue management provisions of 10 CFR Part 26. The points raised include the following:
- Additional time will be needed to finalize software packages for tracking the work-hour restrictions of the rule after publication of the final regulatory guide. NEI noted that publication of the final regulatory guide in May 2009 will allow only 4 months for making any necessary modifications before the fatigue management requirements must be implemented, there are limitations on the resources of vendors coordinating and scheduling software installation at many sites, and time will be required to test the software and train personnel to use it.
- Licensees need to recruit, evaluate, and train increased staff (e.g., a 20-percent increase in security staffing across the industry) to implement the rule.
There may be potential schedule impacts on fall 2009 outages from the need to ensure that there are sufficient reactor operators and senior operators to maintain some operators on nonoutage hours for operating units at multiunit sites; and
- Granting a 6-month period of enforcement discretion will not adversely affect public health and safety and will allow for a more consistent implementation of the rule.
