ROD DROP TIME a
LIMITING CONDITION FOR OPERATION 3.1.3.4 The individual full-length shutdown and control rod drop time from hP 35tt*t the fully withdrawn position shall be less than or equal to 2.2 seconds from beginning of decay of. stationary gripper coil voltage to dashpot entry with:
a.
T greater than.or equal to 551 F, and avg b.
All reactor coolant pumps operating.
APPLICABILITY:
MODES 1 and'2.-
ACTION:
With the rod drop time of any full-length rod determined to exceed a.
the above limit, restore the rod drop time to within the above limit prior to proceeding to MODE 1 or 2.
- b.
- With the rod drop times within limits but determined with three reactor coolant pumps. operating, operation may proceed provided THERMAL POWER is restricted to less than or equal to'66% of RATED THERMAL ~ POWER.
SURVEILLANCE REQUIREMENTS 1.
4.1.3.4 The rod drop time of full-length rods shall be demonstrated through measurement prior to reactor criticality:
For all rods following each removal of the reactor vessel head, a.
b.
For specifically affected individual rods following any maintenance on or modification to the Control Rod Drive System which could affect the drop time of those specific rods, and t
c.
At least once per 18 months.
