TITLE:
CotiDUCT OF OPERATI0t4S PN1-12.12 g py 4.5 Staf f ing and Stadon Opera t ing_Consp_lement - (Cont i nued )
4.5.10 One operator shall man the Radwaste Building at all times.
This is required because the "Radwaste Ahnormal" alatin in Unit I control room no longer exists.
4.5.11 The Shift' operations Supervisor shall determina tha elertness and attentiveness of all operators assigned to safety-related dulles.
If, in the opinion of the Shift Operations Supervisor, an operator does not poJSess these capabilities, he shall be relieved or reassigned to non-safety-related functlons.
It is the responsibility of the person being relieved to ensure that the person assuining his/her pos i t toit is inentally and pliysically alert.
In order to reduce the potential for operator error due to fatigue, it is the plant's policy not to assign operators to shift dutles while in a fatigued conditinn that could significantly reduce their mental aleitness or affect their decialon-making capabilItles.
(NRC/C]
Every effort shall be employed to ensure that a sufficient number of operating personnel remain available to maintain adequate shift coverage without routine rellance on excessive overtime.
The objective, therefore, is to have personnel work an eight-hour day, f ort y-hour week sinder routine operating conditions, llowe ve r, in tlx event that overtime becomes necessary, the following guidelines will be followed:
4,5.11.1 An individual should not be permitted to wotk 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).
4.5.11.2 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 /> in any 24-hour period, nor more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in any 48-hour period, nor more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in any seven-day period (all excluding shift turnover time).
4.5.11.3 A break of at least (H) hours should he allowed between work periods (including shift turnover time).

(NRC Cencric i.a t t e r flo. 82-12) 4.5.12 A weekly. scherble f or Operations personnel will he innued from the Operations Superintendent's Office.
This weekly schedule will normally ansign the anme SRO/ASOS and lead operator ench week from ench group to Unit 2.
The BOP Operator for Unit 2 will be rotated by this schedule every group rotation for purpones of license maintenance and keeping Individuals " fresh" on a near-term operating unit.
Assistant Unit Operators will be rotated on this schedule to maintain qualifications and ensure personnel become experienced on the near-term operating unit.
The Shlft Operations Supervisor will make-control room operator assignments at the beginning of each shift to implement this weekly sd.edule, to be in etfeet for the scheduled period, f.e.,
2230-0630, 0630-1930, 1430-2230 shift period.
The control room assignments will be as follovn:
4.5.12.1 One unit operntor will be designateil nn the lead operator for the shift for each unit.
4.5.12.2 Other unit operators will be assigned an necessary when speelfled by the Operations Superintendent.
