LCO 3.0.1 LCO 3.0.1 establishes the Applicability statementWithin each individual Specification as the requirement for when."

the LCO is required to be met (i.e., when the unit.is' in the MODES or other specified conditions of the Applicability statement of each Specification).

LCO 3.0.2 LCO 3.0.2 establishes that upon discovery of a failure to meet an LCO, the associated ACTIONS shall be met.-.The Completion Time of each Required Action for an ACTIONS Condition is applicable from the point in time that an ACTIONS Condition is entered. The Required Actions establish those remedial measures that must be taken within specified Completion Times when the requirements of an LCO are not met. This Specification establishes that:,

a. Completion of the Required Actions within the.

specified Completion Times constitutes compliance with a Specification: and

b. Completion of the Required Actions is not requiired when an LCO is met within the specified Completion Time, unless otherwise specified'.

There are two basic types of RequiredActions. The first type of Required Action specifies a time limit in which the LCO must be met. This time limit is-the Completion Time to restore an inoperable system or component to OPERABLE status or to restore variables to within specified limits. :If this type of Required Action is not completed within the.-.-

specified Completion Time, a shutdown may be required to" place the unit in a MODE or condition in which the -

Specification is not applicable. (Whether stated as a Required Action or not, correction of the entered Condition is an action that may always be considered upon entering

In this case, compliance with the Required Actions provides an acceptable, level of:safety:for continued operation.

Doing so limits the time, both subsystems/trains of a safety function are inoperable and'limits the time other conditions exist which result in.LCO,3.0.3 being entered. Individual Specifications may specify a"time limit for performing an SR

.when equipment.is removed from service or bypassed for testing. .,In this case, the Completion Times of the Required Actions are applicable when this time limit expires, if the equipment remains removed from.service or bypassed.

When a change in MODE orother~specified condition is required to comply with Required Actions, the unit may enter a: ODE or other specified condition in which another Specification becomes applicable.

Thus, each air lock's structural integrity and leak tightness are essential to the successful.mitigation of such an event.

Each air, lock is required to be OPERABLE. For the air lock to, be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air'lock must be in compliance with the Type.,Bair lock leakage'test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air, lock to be opened at one time.

A containment penetration is considered to be the area bounded by the inboard and outboard CIVs and includes all valves, piping, and connections within this boundary (e.g., vents, drains, and test connections)

(Ref. 7). The containment isolation valve safety function is related to minimizing the loss of reactor coolant inventory and establishing the containment boundary during a DBA. The automatic power operated isolation valves are required to have isolation times within limits and to actuate on an automatic isolation signal. The refueling purge valves must be maintained sealed closed. All manual vent, drain, and test valves within a Containment Penetration (i.e., between the Containment Isolation Valves) will be maintained locked closed per the locked valve administrative program or surveilled closed per Technical Specification SR 3.6.3.3 or SR 3.6.3.4.

The valves covered by this LCO are listed with their associated stroke times in the UFSAR (Ref. 1). The analyses assume the containment is isolated within 60 seconds following an isolation signal (CIAS).

All containment isolation valves are considered to be required except for each 42 inch refueling purge valve when its flow path is isolated with a blind flange tested in accordance with SR 3.6.1.1 as allowed by Note 5 under LCO 3.6.3. This is allowed because the blind flange, instead of the valve, provides the function of the containment boundary.

Required CIVs are considered OPERABLE for LCO 3.6.3 when they are closed (i.e., manual valves are closed, automatic valves are de-activated.and secured in their closed position), blind flanges are in place, and closed systems are intact. The Steam Generating System and the Containment.Pressure Monitoring System are the only credited closed systems at PVNGS. Placement of CIVs in this configuration may impact the operability of the associated system. If the required valve surveillances have lapsed for a CIV secured in its closed (continued)
