SURVEILLANCE REOUIREMENTS 4.1.3.6 Each affected control rod shall be demonstrated to be coupled to its drive mechanism by observin0 any indicated response of the nuclear instrumen-4; tation while withdrawing the control rod to the fully withdrawn position ana then verifying that the ccntrol-rod drive does not go t.o the overtravel
,h, position:
l Prior to reactor criticality after conoleting CORE ALTERATIONS that a.
~
could have affected the control' rod, drive coupling integrity, b.
Anytime the control rod is withdrawn to the ". Full out" position in subsequent operation, and Following maintenance on or audification to the control rod or c.
control rod drive system which could have affected the control rod drive coupling integrity.

$ Limiting Condition for Operation action 3.1.3.6.d. is added:
d.' For control rod 50-27, for the remainder cf Unit 1 Cycle 7, if coupling can not be testablished the uncoupled rod may be wi"hdrawn when rated thermal power exceeds 10% only if all the following conditions ara satisfied:
%)
'N
[
- 1) The uncoupled control rod may not be withdrawn past notch position 46, and
)
- 2) No other uncoupled control rod is withdrawn.

$ Surveillance Requirement 4.1.3.6.d. is added:
- d. When repositioning the uncoupled control rod per Specification 3.1.3.6.d the uncoupled rod's position shall be verified to have followed the control rod drive by neutron instrumentation (LPRM or TIP). If the control blade can not be verified to have followed the drive out to its final position, than the rod shall be completely inserted and the control rod directional valves disarmed as stated in 3.1.3.6.a.2.
