Basis:RPV values are actual levels, not indicated levels. Therefore, they may need levelcompensation depending on conditions.
Loss 2AThreshold
#1 BasisThe Loss threshold represents the EOP requirement for primary containment flooding.
This is identified in the BWROG F-PGsEOPs/SAGsSAMGs when the phrase, "PrimaryContainment Flooding Is Required,"
appears.
Since a site-specific RPV water level isnot specified here, the Loss threshold phrase, "Primary containment flooding required,"
also accommodates the EOP need to flood the primary containment when RPV waterlevel cannot be determined and core damage due to inadequate core cooling isbelieved to be occurring.
Potential Loss 2-,AThreshold
#2 and #3 BasisThis water level corresponds to the top of the active fuel and is used in the EOPs toindicate a challenge to core cooling.The RPV water level threshold is the same as RCS baF-ei-Barrier Loss threshold-24A.
Thus, this threshold indicates a Potential Loss of the Fuel Clad barrier and a Loss of theRCS barrier that appropriately escalates the emergency classification level to a SiteArea Emergency.
This threshold is considered to be exceeded when, as specified in the site-specific EOPs, RPV-wat&RPV water level cannot be restored and maintained above thespecified level following depressurization of the RPV (either manually, automatically orby failure of the RCS barrier) or when procedural guidance or a lack of low pressureRPV injection sources preclude Emergency RPV depressurization.
EOPs allow theMonth 20XXQC 3-25EP-AA-1006 (Revision XX)
Quad Cities AnnexExelon NuclearRECOGNITION CATEGORYFISSION PRODUCT BARRIER DEGRADATION operator a wide choice of RPV injection sources to consider when restoring RPV waterlevel to within prescribed limits. EOPs also specify depressurization of the RPV in orderto facilitate RPV water level control with low-pressure injection sources.
In some events,elevated RPV pressure may prevent restoration of RPV water level until pressure dropsbelow the shutoff heads of available injection sources.
Therefore, this Fuel Clad barrierPotential Loss is met only after either: 1) the RPV has been depressurized, or requiredemergency RPV depressurization has been attempted, giving the operator anopportunity to assess the capability of low-pressure injection sources to restore RPVwater level or 2) no low pressure RPV injection systems are available, precluding RPVdepressurization in an attempt to minimize loss of RPV inventory.
The term "cannot be restored and maintained above" means the value of RPV waterlevel is not able to be brought above the specified limit (top of active fuel). Thedetermination requires an evaluation of system performance and availability in relationto the RPV water level value and trend. A threshold prescribing declaration when athreshold value cannot be restored and maintained above a specified limit does notrequire immediate action simply because the current value is below the top of activefuel, but does not permit extended operation below the limit; the threshold must beconsidered reached as soon as it is apparent that the top of active fuel cannot beattained.
Entry into the "Steam Cooling" leg of the EOP's would be an example of an inability to"restore and maintain" level above TAF resulting in this threshold being met.In high-power ATWS/failure to scram events, EOPs may direct the operator todeliberately lower RPV water level to the top of activ" fuel in order to reduce reactorpower. RPV water level is then contro.lled beteen the top of activ; fu!l and theMinimum Steam Cooling RPV V^ater Level Although such action is achallenge to core cooling and the Fuel Clad barrier, the immediate need to reducereactor power is the higher priority.
For such events, ICs SA5-MA3 or SS5-MS3 willdictate the need for emergency classification.
Since the loss of ability to determine if adequate core cooling is being provided presentsa significant challenge to the fuel clad barrier, a potential loss of the fuel clad barrier isspecified.

If Emergency RPV Depressurization is performed, the plant operators are directed to open safety relief valves (SRVs) and keep them open.

A Max Normal Operating value is the highest value of the identified parameter expectedto occur during normal plant operating conditions with all directly associated supportand control systems functioning properly.
The indicators reaching the threshold barriers and confirmed to be caused by RCSleakage from a primary system warrant an Alert classification.
A primary system isdefined to be the pipes, valves, and other equipment which connect directly to the RPVsuch that a reduction in RPV pressure will effect a decrease in the steam or water beingdischarged through an unisolated break in the system.In general, multiple indications should be used to determine if a primary system isdischarging outside Primary Containment.
For example, a high area radiation condition does not necessarily indicate that a primary system is discharging into the ReactorBuilding since this may be caused by radiation shine from nearby steam lines or themovement of radioactive materials.
Conversely, a high area radiation condition inconjunction with other indications (e.g. room flooding, high area temperatures, reports ofsteam in the Reactor Building, an unexpected rise in Feedwater
: flowrate, or unexpected Main Turbine Control Valve closure) may indicate that a primary system is discharging into the Reactor Building.

Basis:Potential Loess 2.A.The Potential Loss threshold is identical to the Fuel Clad Barrier FC2 Loss threshold RPV Water Level threshold 2.A. The Potential Loss requirement for PrimaryContainment Flooding indicates adequate core cooling cannot be restored andmaintained and that core damage is possible.
BWR EPGsEOPs/SAGsSAMGs specifythe conditions that require primary containment flooding.
When primary containment flooding is required, the EPGsEOPs are exited and SAGsSAMGs are entered.
Entryinto SAGsSAMGs is a logical escalation in response to the inability to restore andmaintain adequate core cooling.PRA studies indicate that the condition of this Potential Loss threshold could be a coremelt sequence which, if not corrected, could lead to RPV failure and increased potential for primary containment failure.
In conjunction with the RPV water level Loss thresholds in the Fuel Clad and RCS barrier columns, this threshold results in the declaration of aGeneral Emergency.

Poten~tial Loss 4. A.The radiation monitor reading corresponds to an instantaneous release of all reactorcoolant mass into the primary containment, assuming that 20% of the fuel cladding hasfailed. This level of fuel clad failure is well above that used to determine the analogous Fuel Clad Barrier Loss and RCS Barrier Loss thresholds.
NUREG-1 228, Source Estimations During Incident Response to Severe Nuclear PowerPlant Accidents, indicates the fuel clad failure must be greater than approximately 20%in order for there to be a major release of radioactivity requiring offsite protective actions.
For this condition to exist- there must already have been a loss of the RCSBarrier and the Fuel Clad Barrier.
It is therefore prudent to treat this condition as apotential loss of containment which would then escalate the emergency classification level to a General Emergency.

Loss 3-.AThreshold
#1 BasisThe use of the modifier "direct" in defining the release path discriminates againstrelease paths through interfacing liquid systems or minor release pathways, such asinstrument lines, not protected by the Primary Containment Isolation System (PCIS).Leakage into a closed system is to be considered only if the closed system is breachedand thereby creates a significant pathway to the environment.
Examples includeunisolable Main Steamline, HPCI or RCIC steamline breaks, unisolable RWCU systembreaks, and unisolable containment atmosphere vent paths.Examples of "downstream pathway to the environment" could be through theTurbine/Condenser, or direct release to the Turbine or Reactor Building.
The existence of a filter is not considered in the threshold assessment.
Filters do notremove fission product noble gases. In addition, a filter could become ineffective due toiodine and/or particulate loading beyond design limits (i.e., retention ability has beenexceeded) or water saturation from steam/high humidity in the release stream.Month 20XXQC 3-41EP-AA-1006 (Revision XX)
Ouad Cities Annex Exelon NuclearRECOGNITION CATEGORYFISSION PRODUCT BARRIER DEGRADATION Following the leakage of RCS mass into primary containment and a rise in primarycontainment
: pressure, there may be minor radiological releases associated withallowable primary containment leakage through various penetrations or systemcomponents.
Minor releases may also occur if a primary containment isolation valve(s)fails to close but the primary containment atmosphere escapes to an enclosed system.These releases do not constitute a loss or potential loss of primary containment butshould be evaluated using the Recognition Category A-R ICs.Loss 3,BThreshold
#2 BasisEOPs may direct primary containment isolation valve logic(s) to be intentionally
: bypassed, even if offsite radioactivity release rate limits will be exceeded.
Under theseconditions with a valid primary containment isolation signal, the containment should alsobe considered lost if primary containment venting is actually performed.
Intentional venting of primary containment for primary containment pressure orcombustible gas control to the secondary containment and/or the environment is a Lossof the Containment.
Venting for primary containment pressure control when not in anaccident situation (e.g., to control pressure below the dPywelDrywell high pressurescram setpoint) does not meet the threshold condition.

#3 BasisThe Max Safe Operating Temperature and the Max Safe Operating Radiation Level areeach the highest value of these parameters at which neither:
(1) equipment necessary for the safe shutdown of the plant will fail, nor (2) personnel access necessary for thesafe shutdown of the plant will be precluded.
EOPs utilize these temperatures andradiation levels to establish conditions under which RPV depressurization is required.
The temperatures and radiation levels should be confirmed to be caused by RCSleakage from a primary system. A primary system is defined to be the pipes, valves, andother equipment which connect directly to the RPV such that a reduction in RPVpressure will effect a decrease in the steam or water being discharged through anunisolated break in the system.In general, multiple indications should be used to determine if a primary system isdischarging outside Primary Containment.
For example, a high area radiation condition does not necessarily indicate that a primary system is discharging into the ReactorBuilding since this may be caused by radiation shine from nearby steam lines or themovement of radioactive materials.
Conversely, a high area radiation condition inconjunction with other indications (e.g. room flooding, high area temperatures, reports ofsteam in the Reactor Building, an unexpected rise in Feedwater
: flowrate, or unexpected Main Turbine Control Valve closure) may indicate that a primary system is discharging into the Reactor Building.

If this action(s) is unsuccessful, operators would immediately pursue additional manual actions at locations away from the reactorcontrol consoles (e.g., locally opening breakers).
Actions taken at back-panels or otherlocations within the Control Room, or any location outside the Control Room, are notconsidered to be "at the reactor control consoles".
Taking the Reactor Mode Switch to SHUTDOWN is considered to be a manual scramaction.The plant response to the failure of an automatic or manual reactor scram will varybased upon several factors including the reactor power level prior to the event,availability of the condenser, performance of mitigation equipment and actions, otherconcurrent plant conditions, etc. If the failure to shutdown the reactor is prolonged Month 20XXQC 3-58EP-AA-1006 (Revision XX)

Depending upon plant responses and symptoms, escalation is also possiblevia IC FS1. Absent the plant conditions needed to meet either IC MSS35 or FS1, anAlert declaration is appropriate for this event.It is recognized that plant responses or symptoms may also require an Alert declaration in accordance with the Recognition Category F ICs; however, this IC and EAL areincluded to ensure a timely emergency declaration.

This event is a precursor to a more significant condition and thus represents a potential degradation of the level of safety of the plant.EAL #1 BasisFollowing the failure on an automatic reactor scram, operators will promptly initiatemanual actions at the reactor control consoles to shutdown the reactor (e.g., initiate amanual reactor scram). If these manual actions are successful in shutting down thereactor, core heat generation will quickly fall to a level within the capabilities of theplant's decay heat removal systems.Month 20XXQC 3-60EP-AA-1006 (Revision XX)

Depending uponseveral factors, the initial or subsequent effort to manually scram the reactor, or aconcurrent plant condition, may lead to the generation of an automatic reactor scramsignal. If a subsequent manual or automatic scram / ARI is successful in shutting downthe reactor, core heat generation will quickly fall to a level within the capabilities of theplant's decay heat removal systems.A manual action at the reactor control consoles is any operator action, or set of actions,which causes the control rods to be rapidly inserted into the core (e.g., initiating amanual reactor scram). This action does not include manually driving in control rods orimplementation of boron injection strategies.
Actions taken at back-panels or otherlocations within the Control Room, or any location outside the Control Room, are notconsidered to be "at the reactor control consoles".
Taking the Reactor Mode Switch to Shutdown is considered to be a manual scramaction.The plant response to the failure of an automatic or manual reactor tscram will varybased upon several factors including the reactor power level prior to the event,availability of the condenser, performance of mitigation equipment and actions, otherconcurrent plant conditions, etc. If subsequent operator manual actions taken at thereactor control consoles are also unsuccessful in shutting down the reactor, then theemergency classification level will escalate to an Alert via IC MSA35. Depending uponthe plant response, escalation is also possible via IC FAI. Absent the plant conditions needed to meet either IC MSA35 or FA1, an Unusual Event declaration is appropriate for this event.A reactor shutdown is determined in accordance with applicable Emergency Operating Procedure criteria.
Should a reactor scram signal be generated as a result of plant work (e.g., RPS setpointtesting),
the following classification guidance should be applied." If the signal generated as a result of plant work causes a plant transient that createda real condition that should have included an automatic reactor scram and the RPSfails to automatically shutdown the reactor, then this IC and the EALs are applicable, and should be evaluated.
" If the signal generated as a result of plant work does not cause a plant transient butshould have generated an RPS scram signal and the scram failure is determined through other means (e.g., assessment of test results),
then this IC and the EALsare not applicable and no classification is warranted.

This IC addresses the difficulty associated with monitoring rapidly changing plantconditions during a transient without the ability to obtain SAFETY SYSTEM parameters from within the Control Room. During this condition, the margin to a potential fissionproduct barrier challenge is reduced.
