REACTIVITY CONTROL SYSTEMS CEA OROP TIME LIMITING CONDITION FOR OPERATION 3.1.3.4 The individual full length (shutdown and regulating) CEA drop time, j
from a fully withdrawn position, shall be less than or equal to 3.0 seconds i
from when the electrical power is interrupted to the CEA drive mechanism until the CEA reaches its 90% insertion position with:
T,yg greater than or equal to 520*F, and a.
b.
All reactor coolant pumps operating.
APPLICA8ILITY:
MODES 1 and 2.
ACTION:
a.
With the drop time of any full length CEA determined to exceed the above limit, restore the CEA drop time to within the above limit prior to proceeding to MODE 1 or 2.
b.
With the CEA drop times within limits but determined at less than full reactor coolant flow, operation may proceed provided THERMAL POWER is restricted to less than or equal to the maximum THERMAL POWER level allowable for the reactor coolant pump combination operating at the time of CEA drop time determination.
SURVEILLANCE REQUIREMENTS 4.1.3.4 The CEA drop time of full-length CEAs shall be demonstrated through measurement prior to reactor criticality:
a.
For all CEAs following each removal and reinstallation of the reactor vessel head, b.
For specifically affected individuals CEAs following any maintenance on or modification to the CEA drive system which could affect the drop time of those specific CEAs, and c.
At each refueling outage.
