D mt0 DUCTION This instruction is intended to describe the criteria used for determining which valves at Calvert Cliffs are to be locked, the o
different types of locking devices to be used, the requirements for l
l rnlocking-valves du' ring various plant modes and the surveillance
. required to verify that these valves are locked.

CRITERI&' FOR IDCKING VAIVES l
A.
Valves are locked to prevent inadvertent operation which could:
1.
Render' systems or equipment necessary fcr the safe operation L
of the plant inoperable, l-2.
-Result in a plant trip.
3.
Result in a radiation release from an unmonitored system.

ECKING DEVICLT I
A..Taert ' r, four methods,which shall be used to secure all valves'
+

centir the criteria listed in 'Section II in a particular position.
Correct application of any of these methods shall-result !n the valve bidng " Locked." The methods to be used are as follows:
'i.
Key Handswitch - For remotely operated-valves without Control Room position indication, a-key handswitch shall be usedLto prevent inadvertent operation.
If manual operation of-such valves is possible, the valve will also be administrative 1y L
locked.
l L
2.
Chain and Padlock - For those valves which can be restrained with a mechanical device to' prevent operation,-a chain with padlock shall be installed.
For valves required to be operated immediately to prevent or terminate an-emergency condition, a break away lock may be used.
Use of breakaway padlocks shall be designated in the applicable valve line-up sheet.

Tamper / Alarm Switch - For fire suppression system isolations;-
alarms in the Control Room.
4.
Administrative Lock - For those remotely operated valves which
. if-chained could damage the valve if it is operated (NOV's), a
. sign will be placed on or near.the valve restricting its use.
B.
All locked valves shall have attached to the valve either a red tas:
to signify locked open or a green tag to signify locked shut.-
V.
SURVE!I, LANCE REQUIRENDrFS A.
All locked valves shall be verified to be in the correct position and-correctly. locked at least-once each eighteen months, unless the Surveillance Test Program or the GS-No requires more frequent
=
t verification, VI.
r m VALVE DEVIATION SHEETS Whenever any locked valve is taken out of'its locked position, suchi deviation shall be. logged in the " Locked. Valve Deviation Log."
This j ;.
includes the repositioning of these s lves for testing. When a locked 1
valve is. repositioned for an STP, and that STP requires the valve to be locked in its normal position and second checked by.a licensed operator, a-locked' valve' deviation is not required. TI.e Locked Valve 1
D Deviation Log need not be used during refueling outages or as determined by the GS-NO (Following a refueling outage, all valve i
lineups for the effected unit containing locked valves are completed).

Locked valve deviation sheets need not be completed for tag outs. Tag l-l' l

CCI-309B'-
FOR INFORMATION ONLY P:32 5
~?
V outs require double verification and thet 11 conned operators be the second cheok'er for locked valves.
Whenever possible, prior to the '
i valve being placed in the "Out of Normal Position," the Control Room Operator (CRO) shall log the valve (s) on the locked valve deviation sheet.
In all cases, the Control Room Supervisor (CRS) shall approve the' locked valve deviation prior to the valve being placed in the "Out of Normal Position". The operator placing the valve in the "Out of:
Normal Position" shall also' initial the locked valve deviation sheet after the valve has been operated.
When a valve is placed in an abnormal position and that abnormal position 'is required to support a flow path per Technical Specification (example':
13 SW pp lined up to-11 SW Hdr, with.11 SW pp OOS) then the valve shall be locked in that
+
abnormal pasition. Do not change the valves' red or green tag, since L
this tag signifies normal valve position.
Once: the valve is returned to its normal position and locked, it shall be cleared-from the -log by an entry in the " returned to normal position" column.
Independent-I L
L verification by two operstors (the second checker must be a licensed-operator) must be indicated by their initials when the valve is I
returned to normal. Thr, CRS will then initial the locked valve j
deviation sheet to verify he was notified the valve was returned to normal. The verification should be completed within four hours, and-before the end of the shift that the valve wcs returned to its normal position.
