a REACTIVITY CONTROL SYSTEMS 3/4.1.3-CONTROL RODS CONTROL ROD OPERABILITY LIMITING CONDITION FOR OPERATION 3.1.3.1 All control rods shall be OPERABLE.

APPLICABILITY: OPERA"'IONAL CONDITIONS 1 and 2.-

ACTION:

a.

With ona control inoperable due to being immovable, as a result of excessive friction or-mechanical interference, or known to be -

untrippable:

1.

Within one hour:

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Verify that the inoperable control rod, if withdrawn, is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 hydraulically by closing the insert and withdraw isolation valves.

\\

2.

Otherwise, be in at least HCTE SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

3.

b.

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

r 1.

If the inoperable control rod (s) is withdrawn, within one hour:

a)

Verify that the inoperable withdrawn control rod (s) ~ is separated from all other inoperable control rods by at least two control cells in all directions, and b)

Demonstrate the insertion capability of the inoperable withdrawn control rod (s) by inserting the control rod (s) at least one notch by drive water pressure within the normal ooerating range *, or c)

Fully insert the inoperable withdrawn control rod (s) and disarm the associated directional control valves either:

1)

Electrically, or 2)

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

SURVZILLANCE REOUIREMENTS 4.1.3.1.1 The scram-discharge volume drain and vent valves shall be demonstrated OPERAB15 at least once pe* 31 days by:*

l a.

Verifying each valve to be open.

s b.

Cyclirg each valve at least one complete cycle of full travel.

l 4.1.3.1.2 All withdrawn control rods not required to have their directional control valves disarmed electrically or hydraulically shall be demonstrated OPERABLE by moving each control rod at least one notch:

a.

At least once per 7 days when aboie the preset power level of the RWM and RSCS, and b.

At least once per 24 ticurs when above the preset power level of the RWM and RSCS and any control rod is immovable as a result of excessive friction or mechanical interference.

1 4.1.3.1.3 All withdrawn control rods shall be determined OPERABLE by demonstrating the enram discharge volume drain and vent valves OPERABLE when control rods are scram tes ted per Specification 4.1.3.2, by verifying that the drain and vent valves:

a.

Close within 30 seconds af ter receipt of a signal for control rods to scram, and b.

Open when the scram signal is reset or the scram discharge volume trip is bypassed.
