ATTACHMENT I ADMINISTRATIVE CONTROLS f.
Administrative procedures shall be developed and implemented to limit the working hours of unit staff who perform safety-related functions; e.g.,
licensed Senior Operators, licensed Operators, health physicists, auxiliary operators, and key maintenance personnel.
Adequate shift coverage shall be maintained without routine heavy use of overtime. The objective shall be to have operating personnel work a normal 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> day with alternating 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> and 36 hour4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> work week while the unit is operating. However, in the event that unforeseen problems require substantial amounts of overtime to be used, or during extended periods of shutdown for refueling, major maintenance or major plant modifications, on a temporary basis, the following guidelines shall be followed:
1)
An individual should not be permitted to work more than 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> straight, excluding shift turnover time; 2)

A break of at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> should be allowed between work periods, including shift turnover time; and 4)
Except during extended shutdown periods, the use of overtime should be considered on an individual basis and not for the entire staff on a shift.
Any deviation from the above guidelines shall be authorized by the Station Manager or his deputy, or higher levels of management, in accordance with established procedures and with documentation of the basis for granting the deviation. Controls shall be included in the procedures such that individual overtime shall be reviewed monthly by the Station Manager or his designee to assure that excessive hours have not been assigned. Routine deviation from the above guidelines is not authorized.

ATTACHMENT II JUSTIFICATION AND SAFETY ANALYSIS The proposed changes to the Technical Specifications concerning overtim normal work day are necessitated by the institution of a twelve hour shift (work day) at the McGuire Nuclear Station.
.The main reason to institute a twelve hour shift at McGuire that this system has been found to be more efficient for the individual workers as well as Duke Power Company.

~ ANALYSIS OF SIGNIFICANT HAZARDS CONSIDERATIONS
~
Pursuant to the requirements of 10CFR50.91, the following analysis provides
-assurance that the proposed changes'in the Technical Specifications would not involve any significant hazards consideration as defined by 10CFR50.92.
The proposed changes in the Technical Specifications are to reflect the current shift work and overtime policies at McGuire Nuclear Station.
The change to the twelve hour work day with alternate 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> and 36 hour4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> work weeks has enhanced the efficiency and safety of operations.
The proposed changes are purely administrative in nature and would not contribute to any accident mechanisms or their consequences.
The proposed amendments would not:
1)
Involve a significant increase in the probability or consequences of an accident previously evaluated; or 2)
Create the possibility of a new or different kind of accident from any accident previously evaluated; or 3)
Involve a significant reduction in a margin of safety.
Based upon the preceding analysis, Duke Power Company concludes that the proposed amendments do not involve a significant hazard consideration.
