APPLICABILITY: MODES 1*.and 2*.
ACTION:
' The ACTION to be taken is based on the cause of inoperability of control rods
~
as follows:
Any immovability of a control rod initially invokes ACTION Statement 3.l'.3.1.a.
Subsequently ACTION Statement 3.1.3.1.a may be exited and ACTION Statement 3.1.3.1.d invoked if either the rod m
control urgent failure alarm is illuminated or an electrical problem is detected in the rod control system.

Immovable-as a result of excessive (a)
(a) friction or mechanical interference or known to be untrippable.
'2.
