l ENCLOSURE 2 Catawba Emergency Plan Section D

. o Catawba Nuclear Site D. EMERGENCY CLASSIFICATION SYSTEM +

Regulatory Guide 1.101, Rev. 3, August 1992, approved the guidance provided by NUMARC/NESP-007, Revision 2, as an alternative methodology for the development of Emergency Action Levels. Catawba Nuclear Site will use the NUMARC guidance for the development of initiating conditions and emergeny I action levels. l The emergency classification system utilizes four categories for classification of l

emergency events.

D.I.a UNUSUAL EVENT Events are in process or have occurred which indicate a potential degradation of the level of safety of the plant. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.

The purpose of this class is to provide notification of the emergency to the station staff, State and Local Government representatives, and the NRC.

Specific initiating conditions and their corresponding emergency action levels are provided in the Basis Document beginning on page D-4.

D.l.b ALERT Events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant. Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.

The purpose of this class is to assure that emergency personnel are readily available to:

1. Activate the onsite response centers
2. Respond if the situation becomes more serious or to perform confirmatory radiation monitoring if required
3. Provide offsite authorities current status information Specific initiating conditions and their corresponding emergency action levels are provided in the Basis Document beginning on page D-4.

D-1

Catawba Nuclear Site D.l.c. SITE AREA EMERGENCY Events are in process or have occurred which involve actual or likely major failures of plant functions needed for protection of the public. Any releases are not expected to result in exposure levels which exceed EPA Protective Action Guideline exposure levels except near the site boundary.

The purpose of the Site Area Emergency is to:

1. Activate the offsite response centers
2. Assure that monitoring teams are mobilized
3. Assure that personnel required for taking protective actions of near site areas are at duty stations should the situation become more serious.
4. Provide current information to the public and be available for consultation with offsite authorities Specific initiating conditions and their corresponding emergency action levels are provided in the Basis Document beginning on page D-4.

D.I.d. GENERAL EMERGENCY Events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity. Releases can be reasonably expected to exceed EPA Protective Action Guideline exposure levels offsite for more than the immediate site area.

The purpose of the General Emergency is to:

1. Initiate predetermined protective actions for the public
2. Provide continuous assessment ofinformation from onsite and offsite measurements
3. Initiate additional measures as indicated by event releases or potential releases
4. Provide current information to the public and be available for consultation with offsite authoritSs Specific initiating conditions and their corresponding emergency action levels are provided in the Basis Document beginning on page D-4.

Catawba Nuclear Site l D.2. INITIATING CONDITIONS The initiating conditions and their corresponding emergency actions levels are contained in the BASIS document beginning on page D-4. A classification procedure (RP/0/A/5000/01) will be used to classify events as they occur. I Specific response procedures are in place which delineate the required response during the appropriate classification.  :

Catawba Nuclear Site ENCLOSURE 4.1 BASIS INFORMATION FOR FISSION PRODUCT BARRIER REFERENCE TABLE CONTAINMENT BARRIER EALs: (C.1 or C. 2 or C. 3 or C. 4 or C. 5 or C. 6 or C. 7)

The Containment Barrier includes the containment building, its connections up to and including the outermost containment isolation valves. This barrier also includes the main steam, feedwater, and blowdown line extensions outside the containment building up to and including the outermost secondary side isolation valve.

Critical Safety Function (CSF) indications are not meant to include transient alarm conditions which may appear during the start-up of engineered safeguards equipment. A CSF condition is satisfied when the alarmed state is valid and sustained.

4.1.C.1 Critical Safety Function Status Containment - RED indicates containment conditions which may challenge the containment integrity. Therefore, this condition represents a potential loss of the containment barrier.

There is no " Loss" EAL associated with this item.

4.1.C.2 Containment Conditions Containment pressure above 15 psig (the design pressure) indicates that the containment or its heat removal systems are not functioning as intended. This degradation of containment pressure control represents a potential loss of containment integrity.

A containment hydrogen concentration of 9 volume percent is sufficient to expect that my ignition would result in complete combustion of the hydrogen in containment and a significant pressure rise. At some initial containment pressures, this pressure rise may exceed the capacity of the containment. Therefore, this level of hydrogen in the containment represents a potential loss of containment integrity.

Containment heat removal systems are actuated at the high-high containment pressure setpoint of 3 psig. At least one train of Containment Spray (NS) and one Containment Air (VX) Return Fan (CARF) should be actuated at that time (the CARF with a 10 minute delay). A failure to actuate the design basis heat removal capability or assure proper containment mixing represents a degradation in the control of the D-4

Catawba Nuclear Site containment conditions. Therefore, this situation represents a potential loss of containment integrity.

Rapid unexplained loss of pressure (i.e., not attributable to containment spray or condensation effects) following an initial pressure increase indicates a loss of containment integrity.

Containment pressure and sump levels should increase as a result of the mass and energy release into containment from a Loss of Coolant Accident (LOCA). Thus, sump level or containment pressure not increasing indicates an interfacing systems LOCA which is a containment bypass and a loss of containment integrity, or some other containment pressure boundary failure.

4.1.C.3 Containment Isolation Valve Status A fter Containment Isolation Actuation i

Failure to isolate those containment pathways which would allow containment i atmosphere to be released from containment is a loss of the containment barrier. j l

There is no " Potential Loss" EAL associated with this item. I i

4.1.C.4 Steam Generator (SG) Secondary Side Release With Primary To Secondary Leakage Secondary side releases to atmosphere include those from the condenser air ejector, SG Power Operated Relief Valves (PORVs), atmospheric dump valves, faulted steam lines, and main steam safety valves. Steam releases,in combination with primary to secondary leakage, constitute a bypass of the containment and, therefore, a loss of the containment barrier.

l The appropriate classification can be determined in combination with the SG Tube l Rupture EAL under the Reactor Coolant System (NCS) barrier.

There is no " Potentia' Loss" EAL associated with this item.

l 4.1.C.5 Significant Radioactive Inventory in Containment These values indicate significant fuel damage well in excess of the EALs associated 4 with both loss of Fuel Clad and loss of NCS Barriers. NUREG-1228, Source Estimations During incident Response to Severe Nuclear Power Plant Accidents, indicates that such conditions do not exist when the amount of clad damage is less D-5

Catawba Nuclear Site than 20%. This amount of activity in containment,if released, could have such severe consequences that it is prudent to treat this as a potential loss of containment.

By treating the radioactive inventory in containment as a potential loss, a General Emergency will be declared when the conditions of the fuel clad and NCS barriers are included in the evaluation. This will allow the appropriate protective actions to be recommended.

There is no " Loss" EAL associated with this item.

NOTE: If EMF-53A and EMF-53B are unavailable, readings can be calculated from procedure HP/0/B/1009/06, " Alternative Method for Determining Dose Rates within the Reactor Building."

4.1.C.6 Core Cooling Core Cooling - RED for greater than 15 minutes in this potential loss EAL represents imminent core damage that, if not terminated, could lead to reactor vessel failure and an increased potential for containment failure. The potential for containment challenge as a result of events at reactor vessel failure makes it prudent to consider an unmitigated core damage condition as a potential loss of the containment barrier.

Severe accident analyses (e.g., NUREG-1150) have concluded that function restoration procedures can arrest core degradation within the reactor vessel in a significant fraction of the core damage scenarios, and that the likelihood of containment failure is very small in these events. Given this, it is appropriate to provide a reasonable period to allow function restoration procedures to arrest the core melt sequence. Whether or not the procedures will be effective should be apparent within 15 minutes. The Emergency Coordinator / EOF Director should make the declaration as soon as it is determined that the procedures have been, or will be, ineffective.

There is no " Loss" EAL associated with this item.

4.1.C.7 Emergency Coordinator / EOF Director Judgement This EAL addresses any other factors that are to be used by the Emergency Coordinator / EOF Director in determining whether the containment barrier is lost or potentially lost. In addition, the inability to monitor the barrier should also be incorporated in this EAL as a factor in Emergency Coordinator / EOF Director judgement that the barrier may be considered lost or potentially lost.

The NCS Barrier includes the NCS primary side and its connections up to and including the pressurizer safety and relief valves, and other connections up to and including the primary isolation valves.

4.1.N.1 Critical Safety Function Status NCS Integrity - RED indicates NCS pressure and temperature conditions which may challenge the Reactor Vessel integrity. Heat Sink - RED indicates the ultimate heat sink function is under extreme challenge. Either of these conditions indicate a potentialloss of the NCS Barrier.

There is no " Loss" EAL associated with this item.

4.1.N.2 NCS Leak Rate Small leaks may result in the inability to maintain normal liquid inventory within the NCS by operation of the Chemical and Volume Control System, which is considered as one centrifugal charging pump discharging to the charging header with the letdown line isolated. If letdown cannot be isolated, and a second charging pump is required, this is still considered a potential loss of the NCS barrier. The need for compensatory action to maintain normal liquid inventory is an indication of a degraded NCS barrier and is considered to be a potential loss of the barrier.

The loss of subcooling is the fundamental indication that the inventory loss from the primary system exceeds the capacity of the inventory control systems. If the loss of subcooling is indicated, the NCS barrier is considered lost.

4.1.N.3 SG Tube Rupture Small Steam Generator tube leaks may result in the inability to maintain normal liquid inventory within the Reactor Coolant System (NCS) by operation of the Chemical and Volume Control System, which is considered as one centrifugal charging pump discharging to the charging header with the letdown line isolated. If letdown cannot be isolated, and a second charging pump is required, this is still considered a potential loss of the NCS barrier. The need for compensatory action to maintain nonnal liquid inventory is an indication of a degraded NCS barrier and is considered to be a potential loss of the barrier.

D-7

Catawba Nuclear Site A tube rupture with an unisolable secondary line fault is generally indicated by a reduction in primary coolant inventory, increased secondary radiation levels, and an uncontrolled or complete depressurization of the ruptured SG. This set of conditions represents a loss of the NCS and containment fission product barriers. In conjunction with containment barrier bss #4, this condition will result in the declaration of a Site Area Emergency. Escalation to a General Emergency would be indicated by at least a potential loss of the fuel clad barrier.

Secondary radiation increases should be observed via radiation monitoring of Condenser Air Ejector Discharge, SG Blowdown, Main Steam, and/or SG Sampling System. Determination of the " uncontrolled" depressurization of the ruptured SG should be based on indication that the pressure decrease in the ruptured steam generator is not a function of operator action. This should prevent declaration based on a depressurization that results from an EOP induced cooldown of the NCS that does not involve the prolonged release of contaminated secondary coolant from the affected SG to the environment. This EAL should encompass steam breaks, feed breaks, and stuck open safety or relief valves. These conditions represents a loss of the NCS and containment fission product barriers.

4.1.N.4 Containment Radiation Monitoring An unplanned valid Trip II alarm on EMFs 38,39, or 40 indicates the release of reactor coolant to the containment. This reading is not valid without a corresponding i decrease in NCS inventory and increased makeup rate to the NCS. The Trip II i setpoint is selected to ensure compliance with Selected Licensee Commitment 16.11- l

6. The indicated loss of reactor coolant is identification of a loss of the NCS barrier.

This reading will be less than that specified for Fuel Clad Barrier EAL #3. Thus, this EAL would be indicative of a NCS leak only. If the radiation monitor reading increased to that specified by Fuel Clad Barrier EAL #1 f ml t damage would also be indicated.

There is no " Potential Loss" EAL associated with this item.

4.1.N.5 Emergency Coordinator / EOF Director Judgement This EAL addresses any other factors that are to be used by the Emergency Coordinator / EOF Director in demmining whether the NCS barrier is lost or potentially lost. In addition, the mability to monitor the barrier should also be incorporated in this EAL as a factor in Emergency Coordinator / EOF Director judgement that the barrier may be considered lost or potentially lost.

Core Cooling - ORANGE indicates subcooling has been lost and that some clad j damage may occur. Heat Sink - RED indicates the ultimate heat sink function is i under extreme challenge. Either of these conditions indicate a potential loss of the Fuel Clad Barrier, j Core Cooling - RED indicates significant reactor coolant superheating and core j uncovery. Clad damage under these conditions is likely; therefore, this is indication ofloss of the Fuel Clad Barrier.

4.1.F.2 Primary Coolant Activity Level
The value of 300 Ci/cc Il31 equivalent coolant activity is well above that expected
for iodine spikes and corresponds to about 2% to 5% fuel clad damage. This amount

! of clad damage indicates significant clad damage and thus the Fuel Clad Barrier is considered lost.

There is no equivalent " Potential Loss" EAL for this item.

4.1.F.3 Containment Radiation Monitoring A reading of 117 R/hr on EMF-53A or B is a value which indicates the release of reactor coolant, with elevated activity indicative of fuel damage, into the containment.

Reactor coolant concentrations of this magnitude are several times larger than the maximum concentrations (including iodine spiking) allowed within technical specifications and are therefore indicative of fuel damage (approximately 5% clad failure depending on core inventory and NCS volume). This value is higher than that specified for NCS barrier Loss EAL #4. Thus, this EAL indicates a loss of both the fuel clad barrier and a loss of NCS barrier.

There is no " Potential Loss" EAL associated with this item.

EMERGENCY ACTION LEVEL:

4.2.U.1-1 Plant is not brought to required operating mode within Technical Specifications LCO Action Statement Time.

BASIS:

Limiting Conditions of Operation (LCOs) require the plant to be brought to a required shutdown mode when the Technical Specification required configuration cannot be restored. Depending on the circumstances, this may or may not be an emergency or precursor to a more severe condition.

In any case, the initiation of plant shutdown required by the site Technical Specifications requires a one hour report under 10 CFR 50.72 (b) Non-emergency events. The plant is within its safety envelope when being shut down within the allowable action statement time in the Technical Specifications. An immediate Notification of an Unusual Event is required when the plant is not brought to the required operating mode within the allowable action statement time in the Technical Specifications. Declaration of an Unusual Event is based on the time at which the LCO-specified action statement time period elapses under the site Technical Specifications and is not related to how long a condition may have existed. Other required Technical Specification shutdowns that involve precursors to more serious events are addressed by other System Malfunction, Hazards, or Fission Product Barrier Degradation ICs.

4.3.G.1-3 Analysis of field survey results or field survey samples indicates dose consequences greater than 1000 mrem TEDE or 5000 mrem CDE Adult Thyroid l at the site boundary.

NOTE 1: These EMF readings are calculated based on worst case average annual meteorology, a sixty minute release duration, and design unit vent flow rate.

Calculations by the dose assessment team use actual meteorology, duration, and unit vent flow rate. Therefore, these EMF readings should not be used if dose assessment team calculations are available.

NOTE 2: If dose assessment team calculations cannot be completed in 15 minutes, then valid monitor readings should be used for emergency classification.

BASIS:

Valid means that a radiation monitor reading has been confirmed to be correct.

The 1000 mrem TEDE and 5000 mrem CDE thyroid integrated doses are based on the EPA PAG values given in EPA-400-R-92-001, which indicates that public protective actions are indicated if doses exceed these values. This is consistent with the emergency class description of a general emergency.

l 4.4.A.1-1 The following conditions exist:

a. Valid reactor trip signal received or required.

AND

b. Manual reactor trip from the control room is successful and reactor power is less than 5% and decreasing.

BASIS:

This condition indicates failure of the automatic protection system to trip the reactor. This condition is more than a potential degradation of a safety system in that a front line automatic protection system did not function in response to a plant transient and thus the plant safety has been compromised, and design limits of the fuel may have been exceeded. An Alert is indicated because conditions exist titat lead to potential loss of fuel clad or NCS. Reactor protection system setpoint being exceeded (rather than limiting safety system setpoint being exceeded) is specified here becausa failure of the automatic protection system is the issue. A manual trip is any set of actions by the reactor operator (s) at the reactor control console which causes control rods to be RAPIDLY inserted into the core and brings the reactor suberitical. Operator action to drive rods does NOT constitute a reactor trip, i.e. does not meet the rapid insertion criterion.

Failure of manual trip would escalate the event to a Site Area Emergency.

This EAL addresses loss of functions required for core cooling during cold shutdown and refueling conditions. This IC and associated EALs are based on concerns raised by Generic Letter 88-17 " Loss of Decay Heat Removal." A number of phenomena such as pressurization, vortexing, steam generator U-tube draining, NCS level differences when operating at a mid-loop condition, decay heat removal system design, and level instrumentation problems can lead to conditions where decay heat removal is lost and core uncovery can occur. NRC analyses show that sequences that can cause core uncovery in 15 to 20 minutes and severe core damage within an hour after decay heat removal is lost.

Escalation to the Site Area Emergency is by, " Loss of Water Level in the Reactor Vessel That Has or Will Uncover Fuel in the Reactor Vessel," or by Abnormal Rad Levels / Radiological Effluent ICs.

4.4.S.1-1 The following conditions exist:

a. Valid reactor trip signal received or required.

b. Manual reactor trip from the control room was r20t successful in reducing reactor power to less than 5% and decreasing.

BASIS:

Automatic and manual trip are not considered successful if action away from the reactor control console is required to trip the reactor. This EAL is equivalent to the Suberiticality CSF-RED.

Under these conditions, the reactor is producing more heat than the maximum decay heat load for which the safety systems are designed. A Site Area Emergency is indicated because conditions exist that lead to imminent loss or potential loss of both fuel clad and NCS. Although this IC may be viewed as redundant to the Fission Product Barrier Degradation IC, its inclusion is accessary to better assure timely recognition and emergency response.

. Catawba Nuclear Site LOSS OF SHUTDOWN FUNCTIONS GENERAL EMERGENCY 4.4.G.1 Failure of the Reactor Protection System to Complete an Automatic Trip and Manual Trip was NOT Successful and There is Indication of an Extreme Challenge to the Ability to Cool the Core.

OPERATING MODE APPLICABILITY: Mode 1 (Power Operation)

EMERGENCY ACTION LEVEL:

4.4.G.1-1 The following conditions exist:

a. Valid reactor trip signal received or required.

AND

b. Manual reactor trip from the control room was not successful in reducing reac+or power to less than 5% and decreasing.

AND

c. Either of the following conditions exist:
  • Core Cooling CSF-RED e Heat Sink CSF-RED BASIS Automatic and manual trii are not considered successfulif action away from the reactor control console is required to trip 1 reactor.

Under the conditions of this IC auf its associated EALs, the efforts to bring the reactor subcritical have been unsuccessful and, as a result, the reactor is producing more heat than the maximum decay heat load for which the safety systems were designed.

The extreme challenge to the ability to cool the core is intended to mean that the core exit temperatures are at or approaching 1200 F or that the reactor vessel water level is below the top of activo fuel. This equates to a Core Cooling-RED condition.

Another consideration is the inability to initially remove heat during the early stages of this sequence. If emergency feedwater flow is insufficient to remove the amount of heat required by D-35

o Catawba Nuclear Site design from at least one steam generator, an extreme challenge should be considered to exist.

This equates to a Heat Sink-RED condition.

In the event either of these challenges occurs during or following a time that the reactor has not been brought below the power associated with the safety system design, core damage may be imminent. For this reason, the General Emergency declaration is intended to be anticipatory of the fission product barrier matrix declaration to permit maximum offsite intervention time.

BASIS:

Loss of all AC power compromises all plant safety systems requiring electric power including RHR, ECCS, Containment Heat Removal and the Ultimate Heat Sink. Prolonged loss of all those functions necessary to maintain hot shutdown will lead to loss of fuel clad, NCS, and containment.

The SSF is capable of providing the necessary functions to maintain a hot shutdown condition for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. No fission product barrier degradation would be expected if the SSF is functioning as intended.

The likelihood of restoring at least one essential bus should be based on a realistic appraisal of the situation since a delay in an upgrade decision based on only a chance of mitigating the event could result in a loss of valuable time in preparing and implementing public protective actions.

In addition, under these conditions, fission product barrier rnonitoring capability may be degraded. Although it may be difficult to predict when power can be restored, it is necessary to give the Emergency Coordinator / EOF Director a reasonable idea of how quickly (s)he may need to declare a General Emergency based on two major considerations:

1. Are there any present indications that core cooling is already degraded to the point that Loss or Potential Loss of Fission Product Barriers is IMMINENT?
2. If there are no present indications of such core cooling degradation, how likely is it that power can be restored in time to assure that a loss of two barriers with a potential loss of the third barrier can be prevented?

Thus, indication of continuing core cooling degradation must be based on Fission Product Barrier monitoring with particular emphasis on Emergency Coordinator / EOF Directorjudgement as it relates to IMMINENT Loss or Potential Loss of fission product barriers and degraded ability to monitor fission product barriers.

The protected area boundary is typically that part within the security isolation zone and is defined in the site security plan.

EALs 1&2: Damage may be caused to some portions of the site, but should not affect ability of safety functions to operate. Method of detection can be based on instrumentation, validated by a reliable source, or operator assessment. As defined in the EPRI-sponsored " Guidelines for Nuclear Plant Response to an Earthquake", dated October 1989, a " felt earthquake" is:

An earthquake of sufficient intensity such that: (a) the vibratory ground motion is felt at the nuclear plant site and recognized as an earthe,uake based on a consensus of control room operators, and (b) valid alarm on seismic instrumentation occurs.

EAL 3: A tornado striking (touching down) within the protected boundary may have potentially damaged plant structures containing functions or systems required for safe shutdown of the plant.

If such damage is confirmed visually or by other in-plant indications, the event may be escalated to Alert.

D-55

Catawba Nuclear Site EAL 4: Addresses such items as a car, truck, plane, helicopter, or train crash that may potentially damage plant structures containing functions and systems required for safe shutdown of the plant.

If the crash is confirmed to affect a plant vital area, the event may be escalated to Alert.

EAL 5: Addresses main turbine rotating component failures of sufficient magnitude to cause observable damage to the turbine casing or to the seals of the turbine generator. Of major concern is the potential for leakage of combustible fluids (lubricating oils) and gases (hydrogen I

cooling) to the plant environs. Actual fires and flammable gas build up are appropriately classified via other EALs. This EAL is consistent with the definition of an Unusual Event while maintaining the anticipatory nature desired and recognizing the risk to non-safety related equipment. Escalation of the emergency classification is based on potential damage done by the I missiles generated by the failure or by the radiological releases in conjunction with a steam generator tube rupture. These latter events would be classified by the Radiological ICs or Fission Product Barrier ICs.

4.7.S.1-1 The following conditions exist:

a. Control room evacuation has been initiated.

AND

b. Control of the plant cannot be established from the ASP or the SSF within 15 minutes.

BASIS:

The timely transfer of control to alternate control areas has not been accomplished. This failure to transfer control would be evidenced by deteriorating reactor coolant system or steam generator parameters. For purposes of classification, the 15 minutes begins at the time that the determination to staff the alternate location is made. For most conditions, Reactor Coolant Pump seal LOCAs or steam generator dryout would be indications of failure to accomplish the transfer in the necessary time.

RP/0/A/5000/01 Enclosure 4.8 Page 1 of 3 DEFINITIONS / ACRONYMS ALERT- Events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant. Any releases are expected to be limited to small fractions of the EPA protective action guideline exposure levels.

BOMB- A fused explosive device CARF - Containment Air Return Fan CIVIL DISTURBANCE - A group of people violently protesting station operations or activities at the site. A civil disturbance is considered to be violent when force has been used in an attempt to injure site personnel or damage plant property.

EPA PAG - Environmental Protection Agency Protective Action Guidelines for exposure to a release of radioactive material.

EXPLOSION - A rapid, violent unconfined combustion, or a catastrophic failure of pressurized equipment that imparts energy of sufficient force to potentially damage permanent structures, systems or components.

EXTORTION - An attempt to cause an action at the site by threat of force.

1 FIRE - Combustion characterized by heat and light. Sources of smoke such as slipping drive belts or overheated electrical equipment do not constitute fires. Observation of flames is preferred but is NOT required if large quantities of smoke and heat are observed.

FUNCTIONAL - A component is fully capable of meeting its design function. It would be declared INOPERABLE if unable to meet Technical Specifications.

GENERAL EMERGENCY- Events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity. Releases can be reasonably expected to exceed EPA protective l action guideline exposure levels outside the Site Boundary.

1 HOSTAGE - A person or object held as leverage against the site to ensure demands will l be met by the site.

l HOSTILE FORCE - One or more individuals present in a PROTECTED AREA without authorization that may have or have threatened to use force in an attempt to injure site personnel or damage plant property.

l IMMINENT - Expected to occur within 1-3 hours.

RP/0/A/5000/01 ,

l Enclosure 4.8 Page 2 of 3 INABILITY TO DIRECTLY MONITOR - Operational Aid Computer data points are unavailable or gauges / panel indications are not readily available to the operator.

INOPERABLE - A component does not meet Technical Specifications. The component may be functional, capable of meeting its design.

INTRUSION / INTRUDER - Suspected hostile individual present in a PROTECTED AREA without authorization.

LOSS - A component is INOPERABLE and not FUNCTIONAL.

s PROLONGED - A duration beyond normallimits, defined as " greater than 15 minutes" or as determined by the judgement of the Emergency Coordinator.

PROTECTED AREA - Encompasses all owner controlled areas within the security perimeter fence.

RUIrTURED (As relates to Steam Generator)- Existence of primary to secondary leakage of a magnitude sufficient to require or cause a reactor trip and safety injection.

S ABOTAGE - Deliberate damage, misalignment, or misoperation of plant equipment with the intent to render the equipment unavailable.

J SIGNIFICANT TRANSIENT- An unplanned event involving one or more of the following: (1) Automatic turbine runback >25% thermal reactor power, (2) Electrical load rejection >25% full electrical load; (3) Reactor Trip, (4) Safety Injection SITE AREA EMERGENCY - Events are in process or have occurred which involve actual or likely major failures of plant functions needed for the protection of the public.

Any releases are NOT expected to result in exposure levels which exceed EPA protective action guideline exposure levels outside the Site Boundary.

SITE BOUNDARY - That area, including the protected area, in which Duke Power Company has the authority to control all activities, including exclusion or removal of personnel and property.

SLC - Selected Licensee Commitments SECURITY EVENT - A security related emergency situation for which prompt response by the Security Force, immediate action by plant personnel, and/or assistance from offsite agencies may be required to apprehend intruders and mitigate the effects of or prevent radiological sabotage.

0 RP/0/A/5000/01 Enclosure 4.8 Page 3 of 3 SUSTAINED - A duration of time long enough to confirm that the CSF is valid (not momentary).

TERMINATION - Exiting the emergency condition.

i TOTAL EFFECTIVE DOSE EQUIVALENT (TEDE) - The sum of external dose exposure to radioactive plume, to radionuclides deposited on the ground by the plume, and the internal exposure inhaled radionuclides deposited in the body.

TOXIC GAS - A gas that is dangerous to life or health by reason ofinhalation or skin contact (e.g. chlorine).

UNCONTROLLED - Event is not the result of planned actions by the plant staff.

UNPLANNED - An event or action is UNPLANNED if it is not the expected result of normal operations, testing, or maintenance. Events that result in corrective or mitigative actions being taken in accordance with abnormal or emergency procedures are UNPLANNED.

UNUSUAL EVENT- Events are in process or have occurred which indicate a potential degradation of the level of safety of the plant. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.

VALID - An indication or report or condition is considered to be VALID when it is conclusively verified by: (1 ) an instrument channel check, or (2) indications on related or redundant instrumentation, or (3) by direct observation by plant personnel such that doubt related to the instrument's operability, the condition's existence or the report's accuracy is removed. Implicit in this definition is the need for timely assessment.

VIOLENT - Force has been used in an attempt to injure site personnel or damage plant property.

VISIBLE DAMAGE - Damage to equipment or structure that is readily observable without measurements, testing, or analyses. Damage is sufficient to cause concern regarding the continued operability or reliability of affected safety structure, system, or component. Example damage: deformation due to heat or impact, denting, penetration, rupture, cracking, paint blistering.

VITAL AREA - Areas within the PROTECTED AREA that house equipment impartant for nuclear safety. Access to a VITAL AREA is allowed only if an individual has been authorized to be in that area.

RP/0/A/5000/01 Enclosure 4.9 Page 1 of 2 EMERGENCY DECLARATION GUIDELINES THE FOLLOWING GUIDANCE IS TO BE USED BY THE EMERGENCY COORDINATOR IN ASSESSING EMERGENCY CONDITIONS.

  • The Emergency Coordinator shall review all applicable initiating events to ensure proper classification.
  • The BASIS Document (located in Section D of the Catawba Nuclear Site Emergency Plan)is available for review if any questions arise over proper classification.
  • If an event occurs on more than one unit concurrently, the event with the higher classification ,

will be classified on the emergency notification fort.; Information relating to the problem on the other unit will be captured on the emergency notification form.

  • If an event occurs, and a lower or higher plant operating mode is reached before the classification can be made, the classification shall be based on the mode that existed at the time the event occurred.
  • The fission product barrier matrix is applicable only to those events that occur at (Mode 1-4) hot shutdown or higher. An event that is recognized at cold shutdown or lower (Mode 5 or 6)

. shall not be classified using the fission product barrier matrix. Reference would be made to i the additional enclosures that provide emergency action levels for specific events (e.g. severe weather, fire, security).

  • If a transient event should occur, the following guidance is provided. )
1. Some emergency action levels specify a specific duration. For these EALs, the - j classification is made when the Emergency Coordinator assessment concludes that the specified duration is exceeded or will be exceeded (i.e. condition cannot be reasonably corrected before the duration elapses), whichever is sooner.

i

2. If a plant condition ex<.eeding EAL criteria is corrected before the specified duration time is excee Jed, the event is NOT classified by that EAL. Lower Severity EALs, if an /, shall be reviewed for possible applicability in these cases.
3. If a plant conditu e xceeding EAL criteria is not recognized at the time of occurrence, but is identified well after the condition has occurred (e.g. as a result of routine log or record review) and the condition no longer exists, an emergency shall NOT be declared. Reporting under 10CFR50.72 may be required. Such a condition could occur, for example, if a follow-up evaluation of an abnormal condition uncovers evidence that the condition was more severe than earlier believed.

RP/0/A/5000/01 Enclosure 4.9 i

Page 2 of 2

4. If an emergency classification was warranted, but the plant condition has been corrected prior to declaration and notification, the Emergency Coordinator must consider the potential that the initiating condition (e.g. Failure of Reactor Protection System) may have caused plant damage that warrants augmenting the an-shift personnel via activation of the Emergency Response Organization. The following are applicable:
a. For UNUSUAL EVENTS, the condition shall be reported. The event may be terminated in the same notification or in a follow-up notification.
b. For ALERT, SITE AREA EMERGENCY, ar.d GENERAL EMERGENCY, the event shall be declared and the emergency response organization activated.

DETERMINATION OF " EVENT TIME" (TIME THE 15 MINUTE CLOCK STARTS)

1. If plant conditions require implementation of EP/l or 2/A/5000/E0 (Reactor Trip or Safety Injection), increased emphasis shall be given to evaluation of plant conditions for  !

determination of EAL(s) when "kickout" of the diagnostic procedure occurs. " Event Time" is the time at which the EAL(s) is determined.

2. If plant conditions do not require implementation of EP/l or 2/A/5000/E0 (Reactor Trip or Safety Inje'ction), and conditions of a specific EAL are met, the " Event Time" is the time at which the EAL(s) is determined.

- 3. The time the event is classified shall be entered on the initial emergency notification form.

MOMENTARY ENTRY INTO A HIGHER CLASSIFICATION If, while in an emergency classification, the specified EALs of a higher classification are met momentarily, and in the judgment of the Emergency Coordinator are not likely to recur, the entry into the higher classification must be acknowledged. Acknowledgment is performed as follows:

If this condition occurs prior to the initial notification to the emergency response organization and off site agencies, the initial message should note that the site is currently in the lower classification, but had momentarily met the criteria for the higher classification. It should also be noted that plant conditions have improved and stabilized to the point that the criteria for the higher classification are not '

l expected to be repeated.
