120 PPL Rev. 10Secondary ContainmentB 3.6.4.1B 3.6 CONTAINMENT SYSTEMSB 3.6.4.1 Secondary ContainmentBASESBACKGROUNDThe secondary containment structure completely encloses the primarycontainment structure such that a dual-containment design is utilized tolimit the spread of radioactivity to the environment to within limits. Thefunction of the secondary containment is to contain, dilute, and hold upfission products that may leak from primary containment into secondarycontainment following a Design Basis Accident (DBA). In conjunction withoperation of the Standby Gas Treatment (SGT) System and closure ofcertain valves whose lines penetrate the secondary containment, thesecondary containment is designed to reduce the activity level of thefission products prior to release to the environment and to isolate andcontain fission products that are released during certain operations thattake place inside primary containment, when primary containment is notrequired to be OPERABLE, or that take place outside primary containment(Ref. 1).The secondary containment is a structure that completely encloses theprimary containment and reactor coolant pressure boundary components.This structure forms a control volume that serves to hold up and dilute thefission products. It is possible for the pressure in the control volume torise relative to the environmental pressure (e.g., due to pump and motorheat load additions).The secondary containment boundary consists of the reactor buildingstructure and associated removable walls and panels, hatches, doors,dampers, sealed penetrations and valves. Certain plant piping systems(e.g., Service Water, RHR Service Water, Emergency Service Water,Feedwater, etc.) penetrate the secondary containment boundary. Theintact piping within secondary containment provides a passive barrierwhich maintains secondary containment requirements. Breaches of thesepiping systems within secondary containment will be controlled to maintainsecondary containment requirements. The secondary containment isdivided into Zone I, Zone II and Zone III, each of which must beOPERABLE depending on plant status and the alignment of thesecondary containment boundary. Specifically, the Unit 1 secondarycontainment boundary can be modified to exclude Zone I1. Similarly, theUnit 2 secondary containment boundary can be modified to exclude ZoneI. Secondary containment may consist of only Zone III when in MODE 4 or5 during CORE ALTERATIONS, or during handling of irradiated fuel withinthe Zone III secondary containment boundary.(continued)SUSQUEHANNA -UNIT 2TS / B 3.6-83Revision 4 PPL Rev. 10Secondary ContainmentB 3.6.4.1BASESBACKGROUND(continued)To prevent ground level exfiltration while allowing the secondarycontainment to be designed as a conventional structure, the secondarycontainment requires support systems to maintain the control volumepressure at less than the external pressure. Requirements for the safetyrelated systems are specified separately in LCO 3.6.4.2, "SecondaryContainment Isolation Valves (SCIVs)," and LCO 3.6.4.3, "Standby GasTreatment (SGT) System." When one or more zones are excluded fromsecondary containment, the specific requirements for support systems willalso change (e.g., required secondary containment isolation valves).APPLICABLESAFETYANALYSESThere are two principal accidents for which credit is taken for secondarycontainment OPERABILITY. These are a loss of coolant accident (LOCA)(Ref. 2) and a fuel handling accident inside secondary containment(Ref. 3). The secondary containment performs no active function inresponse to either of these limiting events; however, its leak tightness isrequired to ensure that the release of radioactive materials from theprimary containment is restricted to those leakage paths and associatedleakage rates assumed in the accident analysis and that fission productsentrapped within the secondary containment structure will be treated bythe SGT System prior to discharge to the environment.Secondary containment satisfies Criterion 3 of the NRC Policy Statement(Ref. 4).LCOAn OPERABLE secondary containment provides a control volume intowhich fission products that bypass or leak from primary containment, orare released from the reactor coolant pressure boundary componentslocated in secondary containment, can be diluted and processed prior torelease to the environment. For the secondary containment to beconsidered OPERABLE, it must have adequate leak tightness to ensurethat the required vacuum can be established and maintained. The leaktightness of secondary containment must also ensure that the release ofradioactive materials to the environment is restricted to those leakagepaths and associated leakage rates assumed in the accident analysis. Forexample, secondary containment bypass leakage must be restricted to theleakage rate required by LCO 3.6.1.3.

Therefore,secondary containment OPERABILITY is required during the sameoperating conditions that require primary containment OPERABILITY.In MODES 4 and 5, the probability and consequences of the LOCA arereduced due to the pressure and temperature limitations in these MODES.Therefore, maintaining secondary containment OPERABLE is notrequired in MODE 4 or 5 to ensure a control volume, except for othersituations for which significant releases of radioactive material can bepostulated, such as during operations with a potential for draining thereactor vessel (OPDRVs), during CORE ALTERATIONS, or duringmovement of irradiated fuel assemblies in the secondary containment.ACTIONS A.1If secondary containment is inoperable, it must be restored to OPERABLEstatus within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

This timeperiod also ensures that the probability of an accident (requiringsecondary containment OPERABILITY) occurring during periods wheresecondary containment is inoperable is minimal.A temporary (one-time) Completion Time is connected to the CompletionTime Requirements above (4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months ) with an "OR" connector.

In such cases, thesecondary containment is the only barrier to release of fission products tothe environment. CORE ALTERATIONS and movement of irradiated fuelassemblies must be immediately suspended if the secondary containmentis inoperable.Suspension of these activities shall not preclude completing an action thatinvolves moving a component to a safe position. Also, action must beimmediately initiated to suspend OPDRVs to minimize the probability of avessel draindown and subsequent potential for fission product release.Actions must continue until OPDRVs are suspended.Required Action C.1 has been modified by a Note stating that LCO 3.0.3 isnot applicable. If moving irradiated fuel assemblies while in MODE 4 or 5,LCO 3.0.3 would not specify any action. If moving irradiated fuelassemblies while in MODE 1, 2, or 3, the fuel movement is independent ofreactor operations. Therefore, in either case, inability to suspendmovement of irradiated fuel assemblies would not be a sufficient reason torequire a reactor shutdown.SURVEILLANCE SR 3.6.4.1.1REQUIREMENTSThis SR ensures that the secondary containment boundary is sufficientlyleak tight to preclude exfiltration under expected wind conditions.Expected wind conditions are defined as sustained wind speeds of lessthan or equal to 16 mph at the 60m meteorological tower or less than orequal to 11 mph at the 1 Om meteorological tower if the 60m tower windspeed is not available.

The intent is to maintain thesecondary containment barrier intact, which is achieved by maintainingthe inner or outer portion of the barrier closed at all times. However, allsecondary containment access doors are normally kept closed, exceptwhen the access opening is being used for entry and exit or whenmaintenance is being performed on an access opening.When the railroad bay door (No. 101) is closed; all Zone I and III hatches,removable walls, dampers, and one door in each access openingconnected to the railroad access bay are closed; or, only Zone Iremovable walls and/or doors are open to the railroad access shaft; or,only Zone III hatches and/or dampers are open to the railroad accessshaft.

This Surveillance is modified by a Note that allowsaccess openings with a single door (i.e., no airlock) within the secondarycontainment boundary (i.e., between required secondary containmentzones) to be opened for entry and exit. Opening of an access door forentry and exit allows sufficient administrative control by individualpersonnel making the entries and exits to assure the secondarycontainment function is not degraded.

To ensure that allfission products are treated, SR 3.6.4.1.4 verifies that the SGT System willrapidly establish and maintain a pressure in the secondary containmentthat is less than the pressure external to the secondary containmentboundary. This is confirmed by demonstrating that one SGT subsystemwill draw down the secondary containment to >_ 0.25 inches of vacuumwater gauge in less than or equal to the maximum time allowed. Thiscannot be accomplished if the secondary containment boundary is notintact.

This Note identifies thateach configuration is to be tested every 60 months. Testing eachconfiguration every 60 months assures that the most limiting configurationis tested every 60 months. The 60 month Frequency is acceptablebecause operating experience has shown that these components usuallypass the Surveillance and all active components are tested morefrequently. Therefore, these tests are used to ensure secondarycontainment boundary integrity.The Unit 1 Railroad Bay can be aligned as a No Zone (isolated fromsecondary containment) or as part of secondary containment (Zone I orIll). Drawdown testing of the secondary containment shall be performedwith the Unit 1 Railroad Bay aligned in the most limiting configuration.More specifically, secondary containment drawdown testing will beperformed with the Unit 1 Railroad Bay aligned as a No Zone with theRailroad Bay door open or as part of secondary containment. The specificalignment will be selected based on the alignment that provides the leastamount of inleakage and drawdown time margin (on a percentage basis)to the acceptance criteria. This could result in one alignment (e.g., NoZone with the Railroad Bay door open) being limiting for one criterion (e.g.,drawdown time) and the other alignment (e.g., Railroad Bay aligned tosecondary containment) being limiting for the other criterion (e.g.,inleakage). It also could result in one alignment being limiting for bothcriteria.Note that aligning the Railroad Bay to either Zone I or III is acceptablesince either zone is part of secondary containment when 3 zone testing isperformed. When a Zone II & III test is performed with the Unit 1 RailroadBay aligned to Secondary Containment, it must be aligned to Zone IIIsince aligning to Zone I will not allow communication with the isolatedzones. The most limiting Unit 1 Railroad Bay alignment shall beestablished each Surveillance period (60 month). Subsequent drawdowntesting during the same Surveillance period only requires testing of theUnit 1 Railroad Bay in the most limiting configuration. For example, Zone1, 11, and III Surveillance testing is performed with the Unit 1 Railroad Bayaligned both as a No Zone with the Railroad Bay door open and as ZoneI1l. If the Surveillance testing determined the most limiting configurationoccurs with the Unit 1 Railroad Bay aligned as Zone III, then subsequentZone II and III drawdown testing during the same Surveillance period onlyneeds to be performed with the Unit 1 Railroad Bay aligned as Zone Il1.(continued)SUSQUEHANNA -UNIT 2TS / B 3.6-89Revision 3 PPL Rev. 10Secondary ContainmentB 3.6.4.1BASESSURVEILLANCEREQUIREMENTSSR 3.6.4.1.4 and SR 3.6.4.1.5 (continued)Since these SRs are secondary containment tests, they need not beperformed with each SGT subsystem.

Secondary containment isolationwithin the time limits specified for those isolation valves designed to closeautomatically ensures that fission products that leak from primarycontainment into secondary containment following a DBA, or that arereleased during certain operations when primary containment is not requiredto be OPERABLE or take place outside primary containment, aremaintained within the secondary containment boundary.The OPERABILITY requirements for SCIVs help ensure that an adequatesecondary containment boundary is maintained during and after an accidentby minimizing potential paths to the environment. These isolation devicesconsist of either passive devices or active (automatic) devices. Manualvalves or dampers, de-activated automatic valves or dampers secured intheir closed position (including check valves with flow through the valvesecured), and blind flanges are considered passive devices.Automatic SCIVs close on a secondary containment isolation signal toestablish a boundary for untreated radioactive material within secondarycontainment following a DBA or other accidents.Other non-sealed penetrations which cross a secondary containmentboundary are isolated by the use of valves in the closed position or blindflanges.APPLICABLESAFETYANALYSESThe SCIVs must be OPERABLE to ensure the secondary containmentbarrier to fission product releases is established. The principal accidents forwhich the secondary containment boundary is required are a loss of coolantaccident (Ref. 1) and a fuel handling accident inside secondary containment(Ref. 2). The secondary containment performs no active function inresponse to either of these limiting events, but the boundary(continued)SUSQUEHANNA -UNIT 2TS / B 3.6-90Revision 3 PPL Rev. 9SCIVsB 3.6.4.2BASESAPPLICABLE established by SCIVs is required to ensure that leakage from the primarySAFETY containment is processed by the Standby Gas Treatment (SGT) SystemANALYSES before being released to the environment.(continued)Maintaining SCIVs OPERABLE with isolation times within limits ensures thatfission products will remain trapped inside secondary containment so thatthey can be treated by the SGT System prior to discharge to theenvironment.SCIVs satisfy Criterion 3 of the NRC Policy Statement (Ref. 3).LCO SCIVs that form a part of the secondary containment boundary are requiredto be OPERABLE. Depending on the configuration of the secondarycontainment only specific SCIVs are required. The SCIV safety function isrelated to control of offsite radiation releases resulting from DBAs.The automatic isolation valves are considered OPERABLE when theirisolation times are within limits and the valves actuate on an automaticisolation signal. The valves covered by this LCO, along with theirassociated stroke times, are listed in Table B 3.6.4.2-1.The normally closed isolation valves or blind flanges are consideredOPERABLE when manual valves are closed or open in accordance withappropriate administrative controls, automatic SCIVs are deactivated andsecured in their closed position, or blind flanges are in place. These passiveisolation valves or devices are listed in Table B3.6.4.2-2. Penetrationsclosed with sealants are considered part of the secondary containmentboundary and are not considered penetration flow paths.Certain plant piping systems (e.g., Service Water, RHR Service Water,Emergency Service Water, Feedwater, etc.) penetrate the secondarycontainment boundary. The intact piping within secondary containmentprovides a passive barrier which maintains secondary containmentrequirements. When the SDHR and temporary chiller system piping isconnected and full of water, the piping forms the secondary containmentboundary and the passive devices in TS Bases Table B3.6.4.2-2 are nolonger required for these systems since the piping forms the barrier. Duringcertain plant evolutions, piping systems may be drained and breachedwithin secondary containment. During the pipe breach, system isolationvalves can be used to provide secondary containment isolation. Theisolation valve alignment will be controlled when the piping system isbreached.(continued)SUSQUEHANNA -UNIT 2TS / B 3.6-91Revision 3 PPL Rev. 9SClVsB 3.6.4.2BASES (continued)APPLICABILITY In MODES 1,2, and 3, a DBA could lead to a fission product release to theprimary containment that leaks to the secondary containment. Therefore,the OPERABILITY of SCIVs is required.In MODES 4 and 5, the probability and consequences of these events arereduced due to pressure and temperature limitations in these MODES.Therefore, maintaining SCIVs OPERABLE is not required in MODE 4 or 5,except for other situations under which significant radioactive releases canbe postulated, such as during operations with a potential for draining thereactor vessel (OPDRVs), during CORE ALTERATIONS, or duringmovement of irradiated fuel assemblies in the secondary containment.Moving irradiated fuel assemblies in the secondary containment may alsooccur in MODES 1, 2, and 3.ACTIONS The ACTIONS are modified by three Notes. The first Note allowspenetration flow paths to be unisolated intermittently under administrativecontrols. These controls consist of stationing a dedicated operator, who isin continuous communication with the control room, at the controls of theisolation device. In this way, the penetration can be rapidly isolated when aneed for secondary containment isolation is indicated.The second Note provides clarification that for the purpose of this LCOseparate Condition entry is allowed for each penetration flow path. This isacceptable, since the Required Actions for each Condition provideappropriate compensatory actions for each inoperable SCIV. Complyingwith the Required Actions may allow for continued operation, andsubsequent inoperable SCIVs are governed by subsequent Condition entryand 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 SCIV.A.1 and A.2In the event that there are one or more required penetration flow paths withone required SCIV inoperable, the affected penetration flow path(s) must beisolated.

The Required Action must be completed within the 8 hourCompletion Time. The specified time period is reasonable considering thetime required to isolate the penetration, and the probability of a DBA, whichrequires the SCIVs to close, occurring during this short time is very low.For affected penetrations that have been isolated in accordance withRequired Action A. 1, the affected penetration must be verified to be isolatedon a periodic basis. This is necessary to ensure that secondarycontainment penetrations required to be isolated following an accident, butno longer capable of being automatically isolated, will be in the isolationposition should an event occur. The Completion Time of once per 31 daysis appropriate because the valves are operated under administrativecontrols and the probability of their misalignment is low. This RequiredAction does not require any testing or device manipulation. Rather, itinvolves verification that the affected penetration remains isolated.Condition A is modified by a Note indicating that this Condition is onlyapplicable to those penetration flow paths with two SCIVs. For penetrationflow paths with one SCIV, Condition C provides the appropriate RequiredActions.Required Action A.2 is modified by a Note that applies to devices located inhigh radiation areas and allows them to be verified closed by use ofadministrative controls. Allowing verification by administrative controls isconsidered acceptable, since access to these areas is typically restricted.Therefore, the probability of misalignment, once they have been verified tobe in the proper position, is low.B.

The SR helps to ensure that post accident leakage of radioactivefluids or gases outside of the secondary containment boundary is withindesign limits. This SR does not require any testing or valve manipulation.Rather, it involves verification (typically visual) that those required SCIVsin secondary containment that are capable of being mispositioned are inthe correct position.Since these SCIVs are readily accessible to personnel during normaloperation and verification of their position is relatively easy, the 31 dayFrequency was chosen to provide added assurance that the SCIVs are inthe correct positions.Two Notes have been added to this SR. The first Note applies to valvesand blind flanges located in high radiation areas and allows them to beverified by use of administrative controls. Allowing verification byadministrative controls is considered acceptable, since access to theseareas is typically restricted during MODES 1, 2, and 3 for ALARAreasons. Therefore, the probability of misalignment of these SCIVs, oncethey have been verified to be in the proper position, is low.A second Note has been included to clarify that SCIVs that are openunder administrative controls are not required to meet the SR during thetime the SCIVs are open.(continued)ISUSQUEHANNA -UNIT 2TS / B 3.6-96Revision 2 PPL Rev. 9SCIVsB 3.6.4.2BASESSURVEILLANCEREQUIREMENTS(continued)SR 3.6.4.2.2SCIVs with maximum isolation times specified in Table B 3.6.2.4-1 aretested every 92 days to verify that the isolation time is within limits todemonstrate OPERABILITY.

If one or both of the blindflanges is removed and all the above identified manual valves for the SDHR system are closed, the appropriate LCO should be enteredfor one inoperable SCIV in a penetration flow path with two SCIVs. With the blind flange removed, the manual valves could be openedintermittently under administrative controls per the Technical Specification Note. When both SDHR blind flanges are installed, opening ofthe manual valves for the SDHR system will be controlled to prevent cross connecting ventilation zones. When the manual valves for theSDHR system are open in this condition, the appropriate LCO should be entered for one inoperable SCIV in a penetration flow path withtwo SCIVs. When the SDHR system piping is connected and full of water, the piping forms the secondary containment boundary and theabove listed SCIVs in Table B3.6.4.2-2 are no longer required for this system since the piping forms the barrier.Note 2: Due to the multiple alignments of the RBCW temporary chiller, different devices will perform the SCiV function depending on theRBCW configuration. There are three devices/equipment that can perform the SCIV function for the RBCW temporary chiller supplypenetration. The first SCIV for the RBCW temporary chiller supply penetration is the installed blind flange on penetration X-29-2-47. Thesecond SCIV for the RBCW temporary chiller supply penetration is isolation valve 187389. The third SCIV for the temporary RBCWchiller supply penetration is closed drain valve 187390 and an installed blind flange on penetrations X-29-5-92 and/or X-29-5-96. Sincethere are effectively three SCIVs, any two can be used to define the SCIV for the penetration. Removal of one of the two required SCIVsrequires entry into the appropriate LCO for one inoperable SCIV in a penetration flow path with two SCIVs. Opening of drain valve187390 and operation of blank flanges X-29-5-96 and X-29-5-92 will be controlled to prevent cross connecting ventilation zones. Thesethree SCIVs prevent air inleakage into secondary containment. The isolation of the penetration per the Technical Specificationrequirement is to assure that one of the above SCIVs is closed so that there is no air inleakage into secondary containment.There are three devices/equipment that can perform the SCIV function for the RBCW temporary chiller return penetration. The first SCIVfor the RBCW temporary chiller return penetration is the installed blind flange on penetration X-29-2-46. The second SCIV for theRBCW temporary chiller return penetration is isolation valve 187388. The third SCIV for the temporary RBCW chiller return penetrationis closed drain valve 187391 and an installed blind flange on penetrations X-29-5-91 and/or X-29-5-95. Since there are effectively threeSCIVs, any two can be used to define the SCIV for the penetration. Removal of one of the two required SCIVs requires entry into theappropriate LCO for one inoperable SCIV in a penetration flow path with two SCIVs. Opening of drain valve 187391 and operation ofblank flanges X-29-5-91 and X-29-5-95 will be controlled to prevent cross connecting ventilation zones. These three SCIVs prevent airinleakage into secondary containment. The isolation of the penetration per the Technical Specification requirement is to assure that oneof the above SCIVs is closed so that there is no air inleakage into secondary containment.When the RBCW temporary chiller piping is connected and full of water, the piping inside secondary containment forms the secondarycontainment boundary and the above listed SCIVs in Table B3.6.4.2-2 are no longer required for this system.Note 3: These penetrations connect Secondary Containment Zone I to a No-Zone. When Secondary Containment Zone I is isolatedfrom the recirculation plenum, the above listed SCIVs in Table B3.6.4.2-2 are no longer required.Note 4: These penetrations connect Secondary Containment Zone II to a No-Zone. When Secondary Containment Zone II is isolatedfrom the recirculation plenum, the above listed SCIVs in Table B3.6.4.2-2 are no longer required.Note 5: These penetrations connect the Railroad Bay to a No-Zone. When the Railroad Bay is a No-Zone, the above listed SCIVs inTable B3.6.4.2-2 are no longer required.Note 6: These penetrations connect Secondary Containment Zone I to the Railroad Bay. The above listed SCIVs in Table B3.6.4.2-2 arenot required if the Railroad Bay is a No-Zone and Zone I is isolated from the recirculation plenum OR if the Railroad Bay is aligned toZone I.Note 7: Due to drain header containing multiple floor drains in different ventilation zones, drain plugs were installed in all of the drainheader floor drains. To provide the passive Secondary Containment boundary, only drain plugs in one ventilation zone are required to beinstalled.SUSQUEHANNA -UNIT 2TS / B 3.6-99cRevision 0
