CONTR01 R0D OPERABILITY LIMITING CONDITION FOR OPERATION 3.1.3.1 All control rods shall be OPERABLE.

APPLICABILITY:

OPERATIONAL CONDITIONS 1 and 2.

ACTION:

a.

With one control rod inoperable due to being immovable, as a result of excessive friction or mechanical interference, or known to be untrippable:

1.

Within 1 hour:

l a)

Verify that the inoperable control rod, if withdrawn, is separated from all other inoperable control rods by at least two control cells in all directions.

b)

Disarm the associated directional control valves

either:

l 1)

Electrically, or 2)

Hydraulically by closing the drive water and exhaust water isolation valves.

c)

Comply with Surveillance Requirement 4.1.1.c.

2.

Otherwise, be in at least HOT SHUTDOWN within 4.he next 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

3.

With one or more control rods trippable but inoperable for causes other than addressed in ACTION a, above:

1.

If the inoperable control rod (s) is withdrawn:

a)

Immediately verify:

1)

That the inoperable withdrawn control rod (s) is separated l from all other inoperable withdrawn control rod (s) by at least two control cells in all directions, and 2)

The insertion capability of the inoperable withdrawn control rod (s) by inserting the control rod (s) at least one notch by drive water pressure within the normal operating range **.

[

b)

Otherwise, insert the inoperable withdrawn control rod (s) and disarm the associated directional control valves

either:

l 1)

Electrically, or 2)

Hydraulically by closing the drive water and exhaust water isolation valves

May be rearmed intermittently, under administrative control, to perrit testing l

associated with restoring the control rod to OPERABLE status.

- The inoperable control rod may then be withdrawn to a position no further l

withdrawn than its position when found to be inoperable.
