ATTACHMENT 1 e
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.,
senior reactor operators, reactor operators, health physicists, auxiliary operators, and key maintenance personnel.
(
Adequate shift coverage shall be maintained without routine heavy use of overtime.
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:
I-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 /> a.
straight, excluding shift turnover time.
b.
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.
A break of at least eight hours should be allowed between work c.
periods, including shift turnover time.
d.
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 Director, Nuclear Plant Operations or his deputy, or higher levels of management, in accordance with established p edure's and with documentation of the basis for granting the deviation.
Controls shall be included in the IS procedures such that individual ov rtime shall be reviewed monthly by the Director, Nuclear Plant Operations or his designee to assure that exces-sive hours have not been assigned.
Routine deviation from the above guidelines is not authorized.

ACTION-With no ECCS subsystem OPERABLE because of the inoperability of either the centrifugal charging pump or the flow path from the a.
refueling water storage tank, restore at least one ECCS subsystem to OPERABLE status within.1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or be in COLD SHUTDOWN within the 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />.
With no ECCS subsystem OPERABLE because of the inoperability of b.
either the residual heat removal heat exchanger or residual heat removal pump, restore at least one ECCS subsystem to OPERABl.E status less'than 350*F by use or maintain the Reactor Coolant System T"V9 of alternate heat removal methods.
In the event the ECCS is actuated and injects water into the Reactor Coolant System, a Special Report shall be prepared and. submitted to c.
the Commission pursuant to Specification 6.9.2 within 90 days describ-
