SR Applicability B 3.0 l
BASES l
SR 3.0.2-The 25% extension does not significantly degrade the (continued) reliability that results from performing the Surveillance at its specified Frequency.
This is based on the recognition that the most probable result of any particular Surveillance being performed is the verification of conformance with the l
SRs.
The exceptions to SR 3.0.2 are those-Surveillances for which the 25% extension of the interval specified in the Frequency does not apply.
These exceptions are stated in the individual Specificatior.s.
The requirements of regulations take precedence over the TS.
Therefore, when a test interval is specified in the regulations, the test interval cannot be extended by the TS, and the SR include a i
Note in the Frequency stating, 'SR 3.0.2 is not applicable."
An example of an exception when the test interval is not
.i specified in the regulations is the Note in the Primary Containment Leakage Rate Testing Program, "SR 3.0.2 is not l
l applicable." This exception is provided because the program already includes extension of test intervals.
j i
l As stated in SR 3.0.2, the.25% extension also does not apply j
to the initial portion of a periodic Completion Time that i
requires performance on a "once per..." basis. The 25%
extension applies to each performance after the initial
)
performance. The' initial performance of the Required i
Action, whether it is a particular Surveillance or some i
other remedial action, is considered a single action with a l-single Completion Time.
One reason for not allowing the 25%
1 extension to this Completion Time is that such an action j
usually verifies that no loss of~ function has occurred by checking the status of redundant or diverse components or accomplishes the function of the inoperable equipment in an j
alternative manner.
The provisions of SR 3.0.2 are not intended to be used l
repeatedly merely as an operational convenience to extend l
Surveillance intervals (other than those consistent with-
~
refueling intervals) or periodic Completion Time intervals beyond those specified.
SR 3.0.3 SR 3.0.3 establishes the flexibility to defer declaring i
affected equipment inoperable or an affected variable outside the specified limits when a Surveillance has not been completed within the specified Frequency.

Primary Containmer..
B 3.6.1.1 B 3.6 CONTAINMENT SYSTEMS B 3.6.1.1 Primary Containment BASES BACKGROUND The function of the primary containment is to isolate and contain fission products released from the Reactor Primary System following a Design Basis Accident (DBA) and to i
confine the postulated release of radioactive material. The primary containment consists of a steel lined, reinforced concrete vessel (for shielding purposes), which surrounds the Reactor Primary System and provides an essentially leak tight barrier against an uncontrolled release of radioactive material to the environment.
1 The isolation devices for the penetrations in the primary containment boundary are a part of the containment leak tight barrier. To maintain this leak tight barrier:
a.
All penetrations required to be closed during accident conditions are either:
1.
capable of being closed by an OPERABLE automatic Containment Isolation System, or 2.
closed by manual valves, blind flanges, or de-activated automatic valves secured in their closed positions, except as provided in LC0 3.6.1.3, " Primary Containment Isolation Valves (PCIVs)";
b.
The primary containment air lock is OPERABLE, except i
as provided in LC0 3.6.1.2, " Primary Containment Air Lock"; and c.
All equipment hatches are closed.
This Specification ensures that the performance of the primary containment, in the event of a DBA, meets the assumptions used in the safety analyses of Reference 1.
SR 3.6.1.1.1 leakage rate requirements are in conformance I
with 10 CFR 50, Appendix J, Option B (Ref. 3), as modified by approved exemptions.
(continued)
PBAPS UNIT 2 B 3.6-1 Revision No.
Anendnent No. 214
B 3.6.1.1 t
BASES (continued) l APPLICABLE The safety design basis for the primary containment is that SAFETY ANALYSES it must withstand the pressures and temperatures of the limiting DBA without exceeding the design leakage rate.
The DBA that postulates the maximum release of radioactive material within primary containment is a LOCA.
In the analysis of this accident, it is assumed that primary containment is OPERABLE such that release of fission products to the environment is controlled by the rate of primary containment leakage.
Analytical methods and assumptions involving the primary containment are presented in Reference 1.
The safety analyses assume a nonmechanistic fission product release following a DBA, which forms the basis for determination of offsite doses.
The fission product release is, in turn, based on an assumed leakage rate from the primary containment. OPERABILITY of the primary containment ensurt 2 that the leakage rate acsumed in the safety analyses is not exceeded.
The maximum allowable leakage rate for the primary containment (L.) is 0.5% by weight of the containment air per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at the design basis LOCA maximum peak containment pressure (P ) of 49.1 psig.
The value of P.
(49.1 psig) is conservative with respect to the current calculated peak drywell pressure of 47.2 psig (Ref. 2).
Primary containment satisfies Criterion 3 of the NRC PolMy Statement.
LC0 Primary containment OPERABILITY is maintained by limiting leakage to s 1.0 L,, except prior to the first startup after performing a required Primary Containment Leakage Rate
~
Testing Program leakage test. At this time, applicable leakage limits must be met.
In addition, the leakage from the drywell to the suppression chamber must be limited to ensure the pressure suppression function is accomplished and the suppression chamber pressure does not exceed design limits. Compliance with this LCO will ensure a primary containment configuration, including equipment hatches, that is structurally sound and that will limit leakage to those leakage rates assumed in the safety analyses.

Primary Containment B 3.6.1.1 BASES LC0 Individual leakage rates specified for the primary (continued) containment air lock are addressed in LC0 3.6.1.2.
APPLICABILITY In MODES 1, 2, and 3, a DBA could cause a release of radioactive material to primary containment.
In MODES 4 and 5, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES.
Therefore, primary containment is not required to be OPERABLE in MODES 4 and 5 to prevent leakage of radioactive material from primary containment.
ACTIONS M
In the event primary containment is inoperable, primary containment must be restored to OPERABLE status within i
1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining primary containment OPERABILITY during MODES 1, 2, and 3.
This time period also ensures that the i
probability of an accident (requiring primary containment OPERABILITY) occurring during periods where primary 1
containment is inoperable is minimal.
B.1 and B 2 If primary containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be i
brought to a MODE in which the LC0 does not apply.
To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The 1
allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full i
power conditions in an orderly manner and without challenging plant systems.

Primary Containment B 3.6.1.1 BASES SURVEILLANCE SR 3.6.1.1.1 (continued)
REQUIREMENTS valve leakage (SR 3.6.1.3.14), does not necessarily result in a failure of this SR.
The impact of the failure to meet these SRs must be evaluated against the Type A, B, and C acceptance criteria of the Primary Containment Leakage Rate Testing Program. As left leakage prior to the first startup after performing a required leakage test is required to be
< 0.6 L, for combined Type B and C leakage, and < 0.75 L, for overall Type A leakage. At all other times between required leakage rate tests, the acceptance criteria is based on an overall Type A leakage limit of s 1.0 L,.
At s 1.0 L, the offsite dose consequences are bounded by the assumptions of the safety analysis.
The Frequency is required by the Primary Containment Leakage Rate Testing Program.
SR 3.6.1.1.2 Maintaining the pressure suppression function of primary containment requires limiting the leakage from the drywell to the suppression chamber.
Thus, if an event were to occur that pressurized the drywell, the steam would be directed through the downcomers into the suppression pool.
This SR is a leak test that confirms that the bypass area between the drywell and the suppression chamber is less than or equivalent to a one-inch diameter hole (Ref. 4).
This ensures that the leakage paths that would bypass the suppression pool are within allowable limits.
The leakage test is performed every 24 months. The 24 month Frequency was developed considering that component failures that might have affected this test are identified by other primary containment SRs.
Two consecutive test failures, however, would indicate unexpected primary containment degradation; in this event, as the Note indicates, a test shall be performed at a Frequency of once every 12 months until two consecutive tests pass, at which time the 24 month test Frequency may be resumed.

I Primary Containment Air Lock B 3.6.1.2 BASES ACTIONS C.1. C.2. and C.3 (continued) f limits.
In many instances (e.g., only one seal per door has failed), primary containment remains OPERABLE, yet only I hour (according to LCO 3.6.1.1) would be provided to restore the air lock door to OPERABLE status prior to i
requiring a plant shutdown.
In addition, even with the 1
overall air lock leakage not within limits, the overall containment leakage rate can still be within limits.
Required Action C.2 requires that one door in the primary containment air lock must be verified closed.
This action must be completed within the 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time.
This specified time' period is consistent with the ACTIONS of LCO 3.6.1.1, which require that primary containment be restored to OPERABLE status within I hour.
Additionally, the' air lock must be restored to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Time is-reasonable for restoring an inoperable air lock to OPERABLE i
status considering that at least one door is maintained j
closed in the air lock.
D.1 and 0.2 If the inoperable primary containment air lock cannot be restored to OPERABLE status within the associated Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.
SURVEILLANCE-SR 3.6.1.2.1 REQUIREMENTS Maintaining primary containment air locks OPERABLE requires compliance with the leakage rate test requireinents of the Primary Containment Leakage Rate Testing Program. This SR reflects the leakage rate testing requirements with respect to air lock leakage (Type B leakage tests).

REQUIREMENTS 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 the Primary Containment Leakage Rate Testing Program.
The SR has been modified by two Notes. Note 1 states that an inoperable air lock door does not invalidate the previous successful performance of the overall air lock leakage test.
This is considered reascnable since either air lock door is capable of providing a fission product barrier in the event of a DBA. Note 2 requires the results of air lock leakage i
tests to be evaluated against the acceptance criteria of the Primary Containment Leakage Rate Testing Program, 5.5.12.
This ensures that the air lock leakage is properly accounted for in determining the combined Type B and C primary containment leakage.
)
SR 3.6.1.2.2 The air lock interlock mechanism is designed to prevent simultaneous opening of both doors in the air lock.
Since both the inner and outer doors of an air lock are designed to withstand the maximum expected post accident primary containment pressure, closure 'of either door will support I
primary containment OPERABILITY.
Thus, the interlock feature supports primary containment OPERABILITY while the air lock is being used for personnel transit in and out of the containment.
Periodic testing of this interlock demonstrates that the interlock will function as designed and that simultaneous inner and outer door opening will not inadvertently occur. Due to the purely mechanical nature of this intarlock, and given that the interlock mechanism is only challenged when primary containment is entered, this test is only required to be performed upon entering primary containment, but is not required more frequently than 184 days when primary containment is de-inerted. The 184 day Frequency is based on engineering judgment and is considered adequate in view of other administrative controls available to operations personnel.

This SR ensures that in case the non-safety grade instrument l
air system is unavailable, the SGIG System will perform its design function to supply nitrogen gas at the required pressure for valve operators and valve seals supported by the SGIG System. The 24 month Frequency was developed considering it is prudent that this Surveillance be l
performed only during a plant outage. Operating experience has shown that these components will usually pass this Surveillance when performed at the 24 month Frequency.
l Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.
SR 3.6.1.3.14 i
The analyses in Reference 1 are based on leakage that is less than the specified leakage rate.
Leakage through each l
MSIV must be 511.5 scfh when tested at 2 P. (25 psig).
This ensures that MSIV leakage is properly accounted for in i
determining the overall primary containment leakage rate.
The Frequency is required by the Primary Containment Leakage Rate Testing Program.
SR 3.6.1.3.15 Verifying the opening of each 6 inch and 18 inch primary containment purge valve and each 18 inch primary containment exhaust valve is restricted by a blocking device to less than or equal to the required maximum opening angle specified in the UFSAR (Ref. 4) is required to ensure that the valves can close under DBA conditions within the times in the analysis of Reference 1.
If a LOCA occurs, the purge i
and exhmt valves must close to maintain primary containment leakage within the values assumed in the accident analysis. At other times pressurization concerns are not present, thus the purge and exhaust valves can be fully open. The 24 month Frequency is appropriate because the blocking devices may be removed during a refueling outage.

J SR Applicability B 3.0 BASES SR 3.0.2 The 25% extension does not significantly degrade the (continued) reliability that results from performing the Surveillance at its specified Frequency.
This is based on the rcccgnition that the most probable result of any particular Surveillance being performed is the verification of conformance with the SRs.
The exceptions to SR 3.0.2 are those Surveillances for which the 25% extension of the interval specified in the 4
Frequency does not apply.
These exceptions are stated in the individual Specifications. The requirements of regulations take precedence over the TS.
Therefore, when a test interval is specified in the regulations, the test interval cannot be extended by the TS, and the SR include a Note in the Frequency stating, "SR 2.0.2 is not applicable."
An example of an exception when the test interval is not specified in the regulations is the Note in the Primary Containment Leakage Rate Testing Program, "SR 3.0.2 is not applicable." This exception is provided because the program already includes extension of test intervals.
As stated in SR 3.0.2, the 25% extension also does not apply to the initial portion of a periodic Completion Time that requires performance on a "once per..." basis. The 25%
extension applies to each performance after the initial performance.
The initial performance of the Required Action, whether it is a particular Surveillance or some other remedial action, is considered a single action with a single Completion Time. One reason for not allowing the 25%
extension to this Completion Time is that such an action usually verifies that no loss of function has occurred by checking the status of redundant or diverse components or accomplishes the function of the inoperable equipment in an alternative manner.
The provisions of SR 3.0.2 are not intended to be used repeatedly merely as an operational convenience to extend Surveillance intervals (other than those consistent with refueling intervals) or periodic Completion Time intervals beyond those specified.
SR 3.0.3 SR 3.0.3 establishes the flexibility to defer declaring affected equipment inoperable or an affected variable outside the specified limits when a Surveillance has not been completed within the specified Frequency.

Primary Containment B 3.6.1.1 B 3.6 CONTAINMENT S STEMS l
B 3.6.1.1 Primary Containment BASES l
BACKGROUND The function of the primary containment is to isolate and contain fission products released from the Reactor Primary System following a Design Basis Accident (DBA) and to j
i confine the postulated release of radioactive material.
The i
primary containment consists of a steel lined, reinforced concrete vessel (for shielding purposes), which surrounds the Reactor Primary System and provides an essentially leak tight barrier against an uncontrolled release of radioactive material to the environment.
The isolation devices for the penetrations in the primary containment boundary are a part of the containment leak tight barrier.
To maintain this leak tight barrier:
a.
All penetrations required to be closed during accident conditions are either:
1.
capable of being closed by an OPERABLE automatic Containment Isolation System, or 2.
closed by manual valves, blind flanges, or de-activated automatic valves secured in their closed positions, except as provided in LCO 3.6.1.3, " Primary Containment Isolation Valves (PCIVs)";
l b.
The primary containment air lock is OPERABLE, except as provided in LCO 3.6.1.2, " Primary Containment Air Lock"; and c.
All equipment hatches are closed.
This Specification ensures that the performance of the primary containment, in the event of a DBA, meets the assumptions used in the safety analyses of Reference 1.
SR 3.6.1.1.1 leakage rate requirements are in conformance l
with 10 CFR 50, Appendix J, Option B (Ref. 3), as modified by approved exemptions.

Primary Containment B 3.6.1.1 BASES (continued)
APPLICABLE The safety design basis for the primary containment is that
)
SAFETY ANALYSES it must withstand the pressures and temperatures of the limiting DBA without exceeding the design leakage rate.
The DBA that postulates the maximum release of radioactive material within primary containment is a LOCA.
In the analysis of this accident, it is assumed that primary containment is OPERABLE such that release of fission products to the environment is controlled by the rate of primary containment leakage.
Analytical methods and assumptions involving the primary containment are presented in Reference 1.
The safety analyses assume a nonmechanistic fission product release following a DBA, which forms the basis for determination of offsite doses. The fission product release is, in turn, based on an assumed leakage rate from the primary containment. OPERABILITY of the primary containment ensures that the leakage rate assumed in the safety analyses is not exceeded.
i The maximum allowable leakage rate for the primary containment (L.) is 0.5% by weight of the containment air per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at the design basis LOCA maximum peak containment pressure (P ) of 49.1 psig. The value of P.
(49.1 psig) is conservative with respect to the current calculated peak drywell pressure of 47.2 psig (Ref. 2).
Primary containment satisfies Criterion 3 of the NRC Policy Statement.
LCO Primary containment OPERABILITY is maintained by limiting leakage to s 1.0 L, except prior to the first startup after performing a required Primary Containment Leakage Rate Testing Program leakage test. At this time, applicable leakage limits must be met.
In addition, the leakage from the drywell to the suppression chamber must be limited to ensure the pressure suppression function is accomplished and the suppression chamber pressure does not exceed design limits. Compliance with this LC0 will ensure a primary containment configuration, including equipment hatches, that is structurally sound and that will limit leakage to those leakage rates assumed in the safety analyses.

Primary Containment B 3.6.1.1 BASES LCO Individual leakage rates specified for the primary (continued) containment air lock are addressed in LC0 3.6.1.2.
APPLICABILITY In MODES 1, 2, and 3, a DBA could cause a release of radioactive material to primary containment.
In MODES 4 and 5, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, primary containment is not required to be OPERABLE in MODES 4 and 5 to prevent leakage of radioactive material from primary containment.
ACTIONS A.1 In the event primary containment is inoperable, primary containment must be restored to OPEkABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining primary containment OPERABILITY during MODES 1, 2, and 3.
This time period also ensures that the probability of an accident (requiring primary containment OPERABILITY) occurring during periods where primary containment is inoperable is minimal.
B.1 and B.2 If primary containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.
SVRVEILLANCE SR 3.6.1.1.1 REQUIREMENTS Maintaining the primary containment OPERABLE requires compliance with the visual examinations and leakage rate test requirements of the Primary Containment Leakage Rate Testing Program.

valve leakage (SR 3.6.1.3.14), does not necessarily result l
in a failure of this SR. The impact of the failure to meet these SRs must be evaluated against the Type A, B, and C acceptance criteria of the Primary Containment Leakage Rate Testing Program. As left leakage prior to the first startup after performing a required leakage' test is required to be
< 0.6 L, for combined Type B and C leakage, and < 0.75 L, for overall Type A leakage. At all other times between required leakage rate tests, the acceptance criteria is based on an overall Type A leakage limit of s 1.0 L,.
. At s 1.0 L, the offsite dose consequences are bounded by the assumptions of the safety analysis.
The Frequency is required by the Primary Containment Leakage Rate Testing Program.
SR 3.6.1.1.2 Maintaining the pressure suppression function of primary containment requires limiting the leakage from the drywell to the suppression chamber.
Thus, if an event were to occur that pressurized the drywell, the steam would be directed through the downcomers into the suppression pool. This SR l
l Is a leak test that confirms that the bypass area between l
the drywell and the suppression chamber is less than or equivalent to a one-inch diameter hole (Ref. 4). This ensures that the leakage paths that would bypass the suppression pool are within allowable limits.
The leakage test is performed every 24 months. The 24 month Frequency was developed considering that component failures that might.have affected this test are identified by other primary containment SRs.
Two consecutive test failures, however, would indicate unexpected primary containment degradation; in this event, as the Note indicates, a test shall be performed at a Frequency of once every 12 months until two consecutive tests pass, at which time the 24 month test Frequency may be resumed.

In many instances (e.g., only one seal per door has failed), primary containment remains OPERABLE, yet only 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (according to LC0 3.6.1.1) would be provided to restore the air lock door to OPERABLE status prior to l
requiring a plant shutdown.
In addition, even with the overall air lock leakage not within limits, the overall containment leakage rate can still be within limits.
Required Action C.2 requires that one door in the primary containment air lock must be verified closed. This action must be completed within the 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time.
This specified time period is consistent with the ACTIONS of LCO 3.6.1.1, which require that primary containment be restored to OPERABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

D.1 and D.2 If the inoperable primary containment air lock cannot be restored to OPERABLE status within the associated Completion l
Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

REQUIREMENTS 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 the Primary Containment Leakage Rate Testing Program.
The SR has been modified by two Notes. Note I states that an inoperable air lock door does not invalidate the previous successful performance of 19 overall air lock leakage test.
This is considered reasorable since either air lock door is capable of providing a fission product barrier in the event of a DBA.
Note 2 requires the results of air lock leakage tests to be evaluated against the acceptance criteria of the Primary Containment Leakage Rate Testing Program, 5.5.12.
This ensures that the air lock leakage is properly accounted for in determining the combined Type B and C primary containment leakage.
SR 3.6.1.2.2 The air lock interlock mechanism is designed to prevent simultaneous opening of both doors in the air lock.
Since both the inner and outer doors of an air lock are designed to withstand the maximum expected post accident primary containment pressure, closure of either door will support primary containment OPERABILITY.
Thus, the interlock feature supports primary containment OPERABILITY while the air lock is being used for personnel transit in and out of the containment.
Periodic testing of this interlock demonstrates that the interlock will function as designed and that simultaneous inner and outer door opening will not inadvertently occur.
Due to the purely mechanical nature of this interlock, and given that the interlock mechanism is only challenged when primary containment is entered, this test is only required to be performed upon entering primary containment, but is not required more frequently than 184 days when primary containment is de-inerted. The 184 day Frequency is based on engineering judgment and is considered adequate in view of other administrative controls available to operations personnel.

considering it is prudent that this Surveillance be performed only during a plant outage. Operating experience has shown that these components will usually pass this Surveillance when performed at the 24 month Frequency.
Therefore, the Frequency was concluded to be acceptable from l
