BASES LCO The primary containment air locks are required to be (continued)
For each air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock i
must be in compliance with the Type B air lock leakage test, i
and both air lock doors mu~st be OPERABLE. The interlock j
allows only one air lock door to be open at a time. This provision ensures that a gross breach of primary containment does not exist when primary containment is required to be j
OPERABLE. Closure of a single door in each air lock is j
sufficient to provide a leak tight barrier following i
postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into a
j and exit from primary containment.
l APPLICABILITY In MODES 1, 2, and 3, a DBA could cause a release of' i
radioactive material to primary containment.
In MODES 4 and 5, the probability and consequences of these events are 3
reduced due to the pressure and temperature limitations of these MODES. Therefore, maintaining OPERABLE primary containment air locks in MODE 4 or 5 to ensure a control volume is only required during situations for which significant releases of radioactive material can be postulated; such as during operations with a potential for draining the reactor vessel (0PORVs), i."..., ::^.:

ACTIONS The ACTIONS are modified by Note 1, which allows entry and i
l exit to perform repairs of the affected air lock component.
l If the outer door is inoperable, then it may be easily accessed for most repairs.
It is preferred that the air lock be accessed from inside primary containment by entering i
through the other OPERABLE air lock. However, if this is not practicable, or if repairs on either door must be performed from the barrel side of the door, then it is permissible to enter the air lock through the OPERABLE door, i
F which means there is a short time during which the primary containment boundary is not-intact (during accesi through j
the OPERABLE door). The ability to open the OPERABLE door, even if it means the primary containment boundary is j
temporarily not intact, is acceptable due to the low probability of an event that could pressurize the primary j
containment during the short time in which the OPERABLE door j
is expected to be open. After each entry and exit, the OPERABLE door must be immediately closed.

This SR reflects the

leakage rate testing requirements with regard to air lock leakage (Type B leakage tests). The acceptance criteria were established during initial air lock and. primary containment OPERABILITY testing. The periodic testing requirements verify that the air lock leakage does not exceed the allowed fraction of the overall primary containment leakage rate. The Frequency is required by 10 CFR 50, Appendix J, as modified by approved exemptions.
Thus, SR 3.0.2 (which allows Frequency extensions) does not apply.
The SR has been modified by three Notes.
Note 1 provides an exception to the specific leakage requirements for the primary containment air locks in other than MODES 1, 2, and 3.
When not operating in MODES 1, 2, or 3, primary containment pressure is not expected to significantly increase above normal, and therefore specific testing at elevated pressure is not required.

BASES
- ' BACKGROUND The function of the secondary containment is to contain, dilute, and hold up fission products that may leak from primary containment following a Design Basis Accident-(DBA).
In conjunction with operation of the Standby Gas Treatment (SGT) System and closure of certain valves whose lines penetrate the. secondary. containment,..the. secondary containment is designed to reduce the activity level of the fission products prior'to release to the environment and to i
isolate and contain fission products that are released during certain operations that take place inside pr7 mary containment'(e.gc, during operations with a potential for l
draining the reactor vessel (0PDRVs),
m..
...,-.m Nor during movement of irradiated fuel I
assemblies in the primary or secondary containment), when primary containment is not. required to be OPERABLE, or that take place outside primary containment.
The secondary containment is a structure that completely
, ~)i encloses the primary containment (except for the upper
(
containment personnel air lock penetration) and those components that may be postulated to contain primary system fluid. This' structure forms a control volume that serves to hold up and dilute the fission products.
It-is possible for the pressure in the control volume to rise relative to the environmental pressure (e.g., due to pump / motor heat load additions). To prevent ground level exfiltration while allowing the secondary containment to be designed as a conventional structure, the secondary containment requires support systems to maintain the control volume pressure at less than the external pressure. Requirements for these systems are specified separately in LCO 3.6.4.2, " Secondary Containment Isolation Dampers (SCIDs)," and LCO 3.6.4.3,
" Standby Gas Treatment (SGT) System."
The isolation devices for the penetrations in the secondary containment boundary are a part of the' secondary containment barrier. To maintain,this barrier:
All secondary containment penetrations required to be a.

LCO An OPERABLE secondary containment provides a control volume into which fission products that bypass or leak from primary containment, or are released from the reactor coolant pressure boundary components located in secondary containment, can be diluted and processed prior to release to the environment. For the secondary containment to be considered OPERABLE, it must have adequate leak tightness to ensure that the required vacuum can be established and maintained.
APPLICABILITY In MODES 1, 2, and 3, a LOCA could lead to a fission' product release to primary containment that leaks to secondary containment. Therefore, secondary containment OPERABILITY is required during the same operating conditions that require primary containment OPERABILITY.
In MODES 4 and 5, the probability and consequences of the s
LOCA are reduced due to the pressure and temperature limitations in these MODES. Therefore, maintaining secondary containment OPERABLE is not required in MODE 4 or 5 to ensure a control volume, except for other situations for which significant releases of radioactive material can be postulated, such as during operations with a potential for draining the reactor vessel (OPDRVs), l. :.., -- L l

LC0 SCIDs form a part of the secondary containment boundary. The SCID safety function is related to control of offsite I

Moving irradiated fuel assemblies in the l
secondary containment may also occur in MODES 1, 2, and 3.
ACTIONS The ACTIONS are modified by three Notes. The first Note allows penetration flow paths to be unisolated intermittently under administrative controls.
These l
l controls consist of stationing a dedicated individual, who is in continuous communication with the control room, at the controls of the isolation device.
In this way, the penetration can be rapidly isolated when the need for l
secondary containment isolation is indicated.
The second Note provides clarification that for the purpose of this LCO separate Condition entry is allowed for each l
penetration flow path. This is acceptable, since the Required Actions for each Condition provide appropriate l
l compensatory actions for each inoperable SCID.
Cpmplying with the Required Actions may allow for continued operation, and subsequent inoperable SCIDs are governed by subsequent Condition entry and application of associated Required
/\\
Actions.
The third Note ensures appropriate remedial actions are taken, if necessary, if the affected system (s) are rendered inoperable by an inoperable SCID.
A.1 and A.2 In the event that there are one or more penetration flow l-paths with one SCID inoperable, the affected penetration flow path (s) must be isolated. The method of isolation must l
include the use of at least one isolation barrier that cannot be adversely affected by a single active failure.
l Isolation barriers that meet this criteria are a closed and de-activated automatic damper, a closed manual damper or valve, or a blind flange.
For penetrations isolated in accordance with Required Action A.1, the device used to isolate the penetration should be the closest available device to secondary containment. This Required Action must be completed within the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> Completion Time.

during this short time.

- Page 28 of 28 Control Room AC System B 3.7.4 BASES ACTIONS E.1, q and E./ 2.(continued)
J During movement of irradiated fuel assemblies in the primary or secondary containment, f
...3 wnc nu uvu wny or during OPDRVs, if the Required Action and associated Completion Time of Condition B is not met, action must be taken to immediately suspend activities that present a potential for releasing radioactivity that might require operation of the Control Room Ventilation System in the high radiation mode.
This places the unit in a condition that minimizes risk.
If applicable, 60RMMefbWiebend handling of irradiated l
fuel in the primary and secondary containment must be suspended immediately. Suspension of these activities shall not preclude completion of movement of a component to a safe position. Also, if applicable, actions must be initiated J
immediately to suspend OPORVs to minimize the probability of a vessel draindown and subsequent potential for fission product release. Actions must continue until the OPDRVs are
)
suspended.
SURVEILLANCE SR 3.7.4.1 REQUIREMENTS This SR verifies that the heat removal capability of the system is sufficient to remove the control room heat load assumed in the safety analysis. The SR consists of a j
combination of testing and calculation. The 18 month Frequency is appropriate since significant degradation of the Control Room AC System is not expected over this time period.
