| PVNGS EMERGENCY PlAN REVISION 69 PAGE8OF383 INTRODUCTION Palo Verde Nuclear (ienerating Station (PVNCiS) isajointly-owned three-unit Pressurized Water Reactor (PWR) power station operated byArizona Public Service (APS). Thestation islocated in Maricopa County, South ot'Wintersburg, Arizona.
| |
| THEPVNGSEMERGENCY PLAN:
| |
| * Describes the organization formed andfacilities availabletomanage emergency situations;
| |
| * Classifies emergencies according toseverity ofconsequences;
| |
| * Dellnes andassigns responsibilities for emergency response actions;
| |
| * Outlines courses ofaction andprotective measures tomitigate theconsequences ofan accident andtosafeguard station personnel and the public;
| |
| * Presents ageneral post-emergency plan andorganization torestore the plant toa normal operating status;
| |
| * Dellnes methods andprocesses toinform the public.
| |
| Theaccidents which might occur atPVNGSare analyzed inChapter 15ofthe PVNGSUFSARin terms ofseverity ofconsequence. TheIndependent Spent Fuel Storage Installation (ISFSI),which isstationary andcentrally located within the PVNGSexclusion area boundary, is analyzed inthe Cask UFSARandsatisfies the requirements for off-normal radiologicaldose. The PVNGS UFSAR analyzed accidents reflectthe design characteristics ofa Pressurized Water Reactor (PWR) and are addressed byPVNGSlimergency Operating Procedures (liOPs) andlimergency Plan Implementing Procedures (EPlPs). Postulated events concerning the ISISIareencompassed bythescheme of EAlsdesignated for PVNGS.

| |
| OF THE PVNGS EMERGENCY PLAN TheEmergency Plan isdesigned to adhere toNuclear Regulatory Commission (NRC) emergency planning regulations andguidelines applicable tocommercial nuclear power stations.TheEmergency Plan isbased upon NRC and Federal Emergency Management Agency (1EMA)guidance ascontained in NUREG-0654/FEMA-REP-l, Revision 1, "Criteria forPreparation andEvaluation ofRadiological Emergency Response Plans and Preparedness in Support of Nuclear Power P lants", and EPA guidance as contained in EPA400-R-92-001, "Manual ofProtective Action Guides and Protective Actions for Nuclear Incidents" October, 1991Radiological emergency planning for the PVNGShas been coordinated with state andlocal emergency response agencies.
| |
| TheState ofArizona andlocal government agencies whomaybeinvolved inemergency response operations areaware ofthe emergency response measures described inthe PVNGSEmergency Plan andareadvised ofchanges ormodifications tothese measures resulting from plan reviews, audits, drillsand/or exercises along with changes to Regulatory guidance.
| |
| Both the Offsite Emergency Response Plan for PVNGSandthe PVNGSEmergencyPlan contain clear-cut dellnitions ofareas ofauthority andresponsibility. TheDEMA, acting under thedirection andauthority ofthe Governor, isresponsible foroverall coordination ofoffsite governmental emergency operations. ThePVNGSEmergency Organization is responsible for onsite emergency operations andfor providing timelyandaccurate plant status information tooffsite emergency authorities. TheArizona Department ofIIealth Services (AzDIIS) has been assigned technical (radiological) responsibility for governmental response within Arizona. Emergency operations withinthe Plume Exposure Pathway EP/arethe responsibility ofMaricopa County.

| PVNGS EMERGENCY PlAN REVISION69 PAGE49OF383 5.0 EMERGENCY CONDITIONSAND CLASSIFICATIONS 5.1 EN1ERGENCY CONDITIONS Emergency classification isdivided into four classification levels. Emergency Action I.evels (EALs), based onindications available inthe control roomandcorrelated tothe emergency classilleations, areprovided tothe operator.
| |
| TheEAlswere discussed andagreed upon byPalo Verde andstate andcounty governmental authorities, andapprovedbythe NRC. EAl s arereviewed with the State andlocal governmental authorities onanannual basis.
| |
| PVNGShas andmaintainsthe capability toassess, classify, anddeclare anemergency condition within 15minutes after the availability ofindications toplant operators that an EAl. has been exceeded. Uponidentincation ofthe appropriate emergency classiBeation level the emergency condition will be promptly declared.
| |
| Thefour emergency classificationlevels are described in the following sections:
| |
| EllERGENCYCl,ASSIFICATION1,EVEl,DESCRIPTIONS There arethree considerations related toemergency elassification levels. These are:
| |
| l)Thepotential impact onradiological safety, either asknown now orascanbe reasonably projected:
| |
| 2)Howlar the plant isbeyond itspredeGned design, safety, andoperating envelopes; and 3)Whether ornotconditions thatthreaten health areexpected tobeconfined to within the site boundary.
| |
| TheTCsdeal explicitly withradiological safety impact byescalating from levels corresponding toreleases within regulatory limits toreleases beyond EPAProtective Action Guideline (PAG) plume exposure levels.
| |
| M Events areinprogress orhave occurred which indicate apotential degradation ofthelevel ofsafety ofthe plant orindicate a security threat tofacility protection has been initiated.
| |
| No releases ofradioactive material requiring offsiteresponse ormonitoring areexpected unless further degradation ofsafety systems occurs.
| |
| | |
| PVNGS EMERGENCY PlAN REVISION 69 PAGE50OF383 ALERT Events areinprogress orhave occurred which involve anactual substantial orpotential degradation of thelevelofsafety ofthe plant ora security event involves that probable life threatening risktositepersonnel ordamage tosite equipment becauseof IIOSTIl I ACTION. Anyreleases areexpected tobelimited tosmall fractions oftheEPAPAG exposure levels.
| |
| Events areinprogress orhaveoccurred which involve actual orlikelymajor titiluresof plant functions needed for protection of thepublic orIIOSTII E ACTIONthat results in intentional damage ormalicious acts:I) toward sitepersonnel orequipment thatcould lead tothe likelyfailureofor; 2) that preventeffective access to,equipment needed forthe protection ofthe public.Anyreleases arenotexpected toresult inexposurelevels which exceed EPAPAGexposure levels beyond the site boundary.
| |
| M Events areinprogress orhave occurred which involve actual orIMMINENTsubstantial core degradation ormelting with potentialfor loss of containment integrity orIIOSTllE ACTIONthat resultsinanactual loss ofphysical control of the Releases facility. canbe reasonably expected toexceed EPAPAGexposure levels offsite for morethan the immediate sitearea.

| |
| * Protective Actions Recommendations (if any)
| |
| Follow UpNotifications areprovided tothe predesignated offsite agency. Thedata transmitted ismutually agreed upon andused forthe purpose ofaidinginthedecision-making process thattakes place offsite.
| |
| 6.4MOHll,IzATION Theemergency organization for anUnusual Eventconsists ofnormalshiftpersonnel.
| |
| Augmentation ofthis organization mayoccur atthediscretionoftheEC.During normal station work hours, notilleation ofonsite EROmayoccur viaPAannouncement, emergency evacuation system and/or mobile devices.
| |
| During off-hours, notification ofEROisaccomplished the byactivating automated callout system. A manual system isalso available if theautomated systemisnotavailable.
| |
| | |
| PVNGS EMERGENCY PIAN REVISION 69 PAGE53OF383 ForanUnusual Event classification, on-shift personnel respondtotheemergency andthe event is directed from the affected unit Control Room/ STSC. Command ofthe situation remains there with the on-shift Emergency Coordinator (EC)untiltermination/recovery or reclassification toahigher level emergency occurs. Foreventsaffecting all three units, command andcontrol isinUnit 1 APS/Palo Verde Communications provides media interface during anUnusual Event.
| |
| Inthe event of an Alert orhigher classification level, the ECorders on-shift the activation ofthe TSC,OSC, EOF, andJIC. Theonsite EROis directed bythe EC-TSC. TheEODin the EOFprovides overall coordination ofthe event anddirection oftheERO.
| |
| 6.5CONSEQUENCE ASSESSMENT Assessment actions will continue throughout the emergency. Continued assessment may result inreclassification ofthe emergency andalteration ofemergency response actions.
| |
| Priority will begiven tocontinuing assessment actions thatresult in:
| |
| * Protective Action Recommendations for the health and safety ofthe general public a Protective Actions for onsite personnel
| |
| * Maintaining control ofthe plant a Resolving anemergency situation
| |
| * Corrective actions toreduce the consequences ofanemergency 6.5.1 Assessment Action for Control ofPlant Operations Theexistence ofanyemergency condition causes increased monitoring ofControl Roominstrumentation tomonitor trends ofappropriateparameters, particularly the indicated values that triggered the emergency andthosethatmayberelated.
| |
| Additional monitoring equipment maybeused the toassess nature ofthe emergency condition. A Safety Parameter Display System (SPDS) display console isinthe Control Roomandisaccessible toControl Roompersonnel.
| |
| 6.5.2Environmental Assessment forProtection oftheIlealth& Safety ofthePublic PVNGShas the responsibility toperform a preliminaryassessment ofthe offsite consequences ofanincident. Environmental AssessmentforProtection ofthe Health andSafety ofthe Public isperformed byPVNGSusing twomethods:
| |
| a DoseAssessment a Environmental Surveys
| |
| | |
| PVNGS EMERGENCY PiAN REVISION69 PAGE54OF383 Dose Assessment isperformed bytrained personnel usingcomputer generated dose projections orother approved methodologies based onplant parameters and/or site eftluent release data. Theinitial assessment will beperformed within 30 minutes of thedeclaration ofanyemergency classification. liPIP's provide recommendations for protective action recommendations whenindicated bydose assessment results.
| |
| Environmental Surveyswill beinitiated asa minimum following the declaration of Alert orhigher. An Environmental Teamwill bedeployed within 30minutes to support these surveys. Environmental Teamsmeasure dose rate readings andnoble gasandiodineconcentrations.
| |
| PVNGSmaintains fully equipped and dedicated vehicles tosupport Environmental Teams. Air monitoringequipment has the capability todetect under field conditions. radioiodine concentrations inair aslow asI-7microcuries per cubic centimeter.
| |
| PVNGSdeploys Survey Teams offsite at least until AzDHShas mobilized its Radiological Emergency Assistance Team (REAT). Approximately three(3) hours isestimated for REATdeployment. Iong-term offsite assessments and dose tothe public (ingestion pathway EPz) arethe responsibility ofAzDilSandsupported by Federal resources.
| |
| Radiological data developed byeither ofthese techniques is used toassess appropriateness ofClassification andProtective Action Recommendations.
| |
| Environmental assessment issupported bya permanent meteorological installation which continuously indicates andrecords wind speed direction andtemperature differentials. Meteorological data maybeobtained from the National Weather Service. This system isdescribed insection 7.3.1 I 6.5.3In-plant Radiological Controls During the course ofanemergency, elevated radiation orcontamination levels may beexperienced. It maythen benecessary toimpose additional radiological controls beyond the controls established bythe normal in-plant radiological controls program.
| |
| In-plant radiological controls inanemergency situation maydiffer from normal radiological control activities inthe following aspects:
| |
| * Maintaining strict access control into affected plantareas
| |
| = Availability anduseofaugmented dosimetry
| |
| | |
| PVNGS EMERGENCY PlAN REVISION69 PAGE55OF383
| |
| * Additional useofportable radiation monitoring devices. particularly high range monitoring devices, il3rmonitoring contamination andarea radiation levels a Increased availabilityanduseofprotective clothing andrespiratory devices
| |
| * Increased air sampling for the purpose oflimiting the number ofpersons subject toexposure a Increased whole body counting andother bio-assays Initialassessment ofthe need tor in-plant radiological controls maybebased on plantreadings, RMS readings,in-plant EPDreadings andsystem status reports.
| |
| Additional information concerning in-plant radiological conditions maybegained during the debriefing ofpersonnel deployed with Emergency Repair andSurvey Teams.
| |
| 6.5.4Reactor CoreDamage Assessment Initialassessment ofthe status of the reactor core isperformed bythe STA.Initial assessment ofcore conditions isbased on readings ofControl Room instrumentation andassessment ofSPDS data.
| |
| PriortoTSCactivation, the STAinthe STSC provides additional capabilityfor assessment ofreactor core damage.
| |
| Whenthe TSCisactivated, the Reactor Analyst assesses core conditions underthe direction ofthe Engineering Manager. Information isobtained fromthe SPDSand criticalparameter values from ERFDADS.
| |
| Palo Verde's Core Damage Assessment program wasdeveloped based onthe Combustion Engineering Owners Group Task Development 4 67, ofthe Comprehensive Procedure Guidelines for CoreDamage Assessment.
| |
| 6.6CORRECTIVEACTIONS PVNGSprocedures contain stepsfor preventive and/or corrective actionstoavoid or mitigate serious consequences ofanincident. These steps are contained in AOP, EOP, and other procedures.
| |
| plant 6.7PROTECTIVE ACTIONS ofprotective A range actions has been developed foremergency workersandthe public.
| |
| Theguidelines for emergency workers are consistent with E PA emergency andworker lifesaving activity protective actionguides.
| |
| | |
| PVNGS EMERGENCY PlAN REVISION 69 PAGE56OF383 Protective actions areemergency measures taken during andafter anemergency sothat onsite personnel andthe general public are alerted andactions areinitiated flarthe protection oftheir healthandsafety. Protective actions areinitiated if radiation orairborne radioactivity levels exceed predetermined values orwhensituations threaten the health andsafety ofonsite personnel orthe general public.
| |
| Theresponsibility for thedetermination ofProtective Actions forWorkers andthe General Public is implemented asfollows:
| |
| * Protective actions for onsite personnel andvisitors arethe responsibility ofthe PVNGSEmergency Coordinator.
| |
| * Protective Actions forEmergency Workers operating under the State orCounty Emergency Plan aretheresponsibility ofthe AzDIIS. Measures for the protection of these Emergency Workers are detailed inthe Offsite Emergency Response Plan for PVNGS.
| |
| * Protective Measures for the General Public are directed bythe Governor ofArizona andimplemented byMaricopa County. It is the responsibility ofPVNGStoprovide Protective Action Recommendations forthe Evacuation and/or Shelter ofthe General Public within theI0Mile EP7inaddition to a recommendation for Potassium lodide whenappropriate. PVNGSincoordination with the State ofArizona (ADEM and AzDIIS) along withMaricopa County have formulated a protective action strategy consistent with the guidance contained within "NDRE(i 0654, Supplement 3,Criteria for Preparation andEvaluation ofRadiological Emergency Response Plans and Preparedness inSupport ofNuclear Power P lants, (inidance for Protective Action Strategies, November 201I. ''
| |
| Measures for the protection ofthe general public aredetailed inthe Offsite Emergency Response Plan for PVNGS.
| |
| 6.7.1PROTECTIVEACTIONFORONSITEPERSONNEl, Protective actions foronsite personnel mayinclude alerting, personnel assembly, accountability, andevacuation aswell assecurity procedures, access control, monitoring anddecontamination. Protective actions mayalso betaken for onsite personnel foremergencies such as11res or natural disasters where personnel safety isthreatened.
| |
| 6.7.I.1Ilostile Action Onsiteprotection ofemployees during ahostile action involves a combination ofrestricted movement, movementtosafe locations, and siteevacuation depending onthe nature ofthe hostile event and advance warning. Site procedures provide specifle actions totake duringhostile actionbased events.
| |
| | |
| PVNGS EMERGENCY Pl,AN REVISION69 PAGE57OF383 6.7.1.2Alerting Unit personnel are alertedbyanaudible signal andanannouncement over the unit public addresssystem. Site personnel arealerted by activation ofanaudible signal followed bypublic address system announcements. Evacuation/accountability isassured inhigh noise workareas bythe useofaudible alarms, flashing lights, and/or administrative measures.
| |
| The PVNGS Site Warning Siren/Public Address System of consists electronic sirenswith four distinct sounds: (I) assembly signal,(2) evacuation signal. (3) firesignal, and(4) all-clearsignal.These signals areintroduced prior toinitial site access andareavailable ona phone recording. The emergency signal canbeactivated from the Control Room,and the TSC.
| |
| 6.7.1.3Assembly Personnel assembly ismandatory atthe Site Area Emergency orhigher level classification. Assembly of site personnel outside ofthe Protected Areas isaccomplished byall personnel reporting todesignated assembly areas. Assembly maybeinitiated atanytime site management deems i t appropriate for personnel safety reasons.Inthe case ofahostile actionthreatorevent. designated assembly points will beannounced via thePublic Address System. The designated assembly points mayinclude onsiteassembly points oroffsite mustering points.
| |
| Assembly mayalso beused asa tool toinitiate theTwo-Man Rule during Security events.
| |
| 6.7.I.4Accountability Personnel accountability within the Protected Areais mandatory atthe Site Area Emergency. Accountability maybeinitiated atother timesat the discretion ofthe ECtosupport worker safety.
| |
| Accountability ofpersonnel within theProtected Areas isaccomplished within 30minutes ofthe declaration ofSite AreaEmergency orhigher, andmaintained continuously thereafter. using ProtectedArea(s) boundary access controlasdescribed inthe PVNGSSecurity Plan.If there arestation personnelwhoareunaccounted for,the Unit Evacuation System andsitewide page areused tolocate them. or,in extreme cases (fire,toxicgasrelease, exp:osions, structuraldamage,
| |
| | |
| PVNGS EMERGENCY PlAN REVISION69 PAGE58OF383 trained etc.), search andrescue personnel aredeployed tosearch forand assistthe missing personnel.
| |
| 6.7.1.5 Evacuation Thedecision toevacuate non-essential personnel ismadebythe l?C.
| |
| Nonessential personnel mustbeevacuated inthe event ofa Site Area Emergency orGeneral Emergency. Ilowever. incertain situations it may bedesirable toevacuate earliertoenhance worker protection.
| |
| 6.7.I.6Security andAccess Control PVNGS Security personnel atSecurity Access Control Pointsare instructed to admit only emergencypersonnel anddesignated County, StateandNRC personnel. Special onsite security measures have been developed tofacilitate rapid access byemergency response personnel.
| |
| Incase ofa Securitycontingency eventsuch asa direct armed attack, Security's response actions may beprimarilyfocused onthe Security event andtake precedence over emergency response duties.

| PVNGS EMERGENCY PlAN REVISION 69 PAGE96OF383 9.0 RECOVERY Recovery operations include long termpost-emergency efforts thatfollow a major incident.
| |
| These operations are performed bystation personnel, contract expertsandspecialists, and qualified engineers under the direction ofthe recovery organization. Post-accident recovery actions aredesigned toidentify the extentofplant damage. prepare specific plans and programs forstation repairand restoration, implement recovery plansandprograms, and return the plant to a normal operating status.
| |
| Thefollowing plant status conditions serveasgeneral guidelines fordecisions onthe initiation ofpost-emergency recovery efforts:
| |
| a Radiation levels arestable ordecreasing with time
| |
| * Releases ofradioactive materials to the environment have ceased orarecontrolled within permissible license limits
| |
| * Fire orsimilar emergency conditions nolonger constitute a hazard tothe plant orstation personnel a Measures have been successfully tocorrect orcompensate instituted tormalfunctioning equipment.
| |
| Based onconsideration ofthese criteria,aswell asother pertinent items,the EODdetermines whentoactivate the recovery organization. Manpower andequipment resources supporting the individual functional segments oftherecovery organization may vary according tothe severity ofdamage andspecille situational needs.
| |
| Intering into recovery will notnecessarily resultinde-escalation ofthe emergency classification inthat, the loss ofa tission product barrier maynotberecoverable until recovery iscomplete. Entering into recoverydenotes the plant isstable andfurther degradation isunlikely. Repair andrestoration ofplant systems willbeneeded tofully exit the recovery phase.

| |
| Decision-makers responsible for implementation ofEP-0901, Classifications, mayusethis document asa technical reference insupport ofEAl interpretation. This information mayassist the Emergency Coordinator inmaking classifications,particularly those involvingjudgment ormultiple events. Thebasis inti)rmation mayalso beuseful intraining andfor explaining event classifications tooffsite officials.
| |
| Theexpectation isthat emergency classifleations aretobemadeassoonasconditions arepresent andrecognizable for the c lassitleation, butwithin15minutes orless inallcases ofconditions present. Useofthis document for assistance is notintended todelay theemergency classification.
| |
| Because the infl)rmation ina basis document can affect emergency classillcation decision-making (e.g.. the Emergency Coordinator refers toitduring anevent), the NRCstaff expects that changesto the basis document will beevaluated inaccordance with the provisions of10CFR50.54(q).

| 2.0 DISCUSSION
| |
| | |
| ===2.1 Background===
| |
| EAlsarethe plant-specille indications, conditions orinstrument readngs that areutilized to classify emergency conditions defined inthePVNGSEmergency Plan.
| |
| In1992, the NRCendorsed NUMARC/NESP-007, Methodology forDevelopment oflimergency Action I.evels.asanalternative toNUREG-0654 EAlguidance.
| |
| NEl99-01 (NUMARC/NESP-007), Revisions 4 and5,were subsequently issued flarindustry implementation. Enhancements over earlierrevisions included:
| |
| a Consolidating the system malfunction initiating conditions andexample emergency action levels which address conditions thatmaybepostulated tooccur during plant shutdown conditions.
| |
| * Initiating conditions andexample emergency actionlevels that fullyaddress conditions that maybepostulated tooccur atpermanently Defueled StationsandIndependent Spent Fuel Storage Installations (ISFSls).
| |
| a Simplifying the flssion product barrier EAlthreshold fora Site Area Emergency.
| |
| Subsequently. Revision 6ofNEl99-01 incorporated resolutions tonumerous implementation issues including the NRCl?Al Frequently Asked Questions (FAQs). Using NEl99-01, Revision 6, 3of262
| |
| | |
| PVNGS EMERGENCY PlAN REVISION69 PAGE125 OF383 Methodology for the Development ofEmergency Action Levels for Non-Passive Reactors, November 2012 (ref. 4.1.1 L PVNGSconducted anEAL implementation upgrade project that produced the EAl.sdiscussed herein.
| |
| 2.2 Fission Product Barriers Fission product barrier thresholds represent threats tothe defense indepth design concept that precludes the releaseof radioactive fission products tothe environment. This concept relies on multiple physical barriers, any oneofwhich. ifmaintained intact, precludes the release of significant amountsofradioactive fission products tothe environment.
| |
| Manyofthe EAlsderived from the NEl methodology arefission product barrier threshold based.
| |
| That is,the conditions that define the EAl sarebased uponthresholds that represent the lossor potential loss ofoneormoreofthe three 11ssion product barriers. "I.oss" and"Potential I.oss" signify the relative damage andthreat ofdamage tothe barrier. A "Ioss" threshold means the barrier nolonger assures containment ofradioactive materials. A "Potential Loss" threshold implies anincreased probability ofbarrier lossanddecreased certainty ofmaintaining thebarrier.
| |
| Theprimary Assion product barriers are:
| |
| A. Fuel ClaEl'C.J. TheFCBarrier consists ofthe cladding material that contains the fuel pellets.
| |
| B. W TheRCSBarrier includes the RCS primary side andits connections uptoandincluding the pressurizer safety andrelief valves andother connections up to and including the primary isolation valves.
| |
| C.ContainmenUC).M D TheCTMTBarrier includes the containment building and connections uptoandincluding the outermost containment isolation valves. This barrier alsoincludes the main steam, feedwater andblowdown lineextensions outsidethe containment building uptoandincluding theoutermost secondary side isolationvalve.
| |
| Containment Barrier thresholds areused ascriteria for escalation ofthe emergency classification level (ECL) from Alert toa Site AreaEmergency ora General limergency 2.3 Fission Product Barrier Classification Criteria Thefollowing criteria arethe bases forevent classificationrelated tofission product barrier loss or potential loss:

| |
| * Division ofthe EALsetinto three broad groups:
| |
| o EALsapplicable undera.ny plant operating modesThis -
| |
| group would bereviewed bythe EAL-useranytimeemergency classification is considered.
| |
| o EAl.s applicableonlyunder hotoperating modesThis -
| |
| group would only be reviewed bytheEAL-user whenthe plant isin1 Power-Operation, 2 Startup, 3 -
| |
| IlotStandby or4 Ilot Shutdown mode.
| |
| o IAl.s applicableonly under cold operating modes -
| |
| Thisgroup would only be reviewed bytheEAI-user whenthe plant isin5 -
| |
| Cold Shutdown, 6 Refueling or Defueled mode.
| |
| Thepurpose ofthe groups istoavoid review ofhot condition EAI.s when the plant is ina cold condition andavoid review ofcold condition EAlswhenthe plant isina hot condition. This approach significantly minimizesthe totalnumber ofEAlsthat mustbereviewed bythe userfor a given plant condition, reduces user reading burden thereby, and, facilitatestimelyidentification of the EAl. that applies tothe emergency.
| |
| * Within each group. assignment ofEALstocategories andsubcategories:
| |
| Category andsubcategory titles areselected torepresent conditions thatare operationally significant tothe EAI.-user. ThePVNGSEAI categories arealigned toand represent theNII99-01"Recognition Categories." Subcategories are used inthe PVNGSscheme asnecessary tofurther divide the EAIsofa category into logical sets ofpossible emergency classification thresholds. The PVNGSEAl. categories andsubcategories arelisted below.

Forevents that occur inCold Shutdown orRefueling, escalation isvia EAlsthat are applicable inthe Cold Shutdown orRefueling modes, evenif HotShutdown (or a higher mode) is entered during the subsequent plant response. In particular, the tission product barrierEAIsare applicable only toevents that initiate inthe Hot Shutdown mode orhigher.
| |
| 3.0 GUIDANCEONMAKINGEMERGENCYCI ASSIFICATIONS 3.1General Considerations Whenmaking anemergency elassification, the Emergency Coordinator mustconsider all infl>rmation having a bearing on the proper of assessmentanInitiating Condition (IC). This includes theEmergency Action I.evel(EAl )plus the a ssociated Operating Applicability, Mode Notes and theinfl3rming basis information. Inthe Recognition Category Fmatrices.EALs arebased onloss or potentialloss ofFission Product Barrier Thresholds.
| |
| 3.1IClassification Timeliness NRCregulations require the licensee toestablish andmaintain the capabilitytoassess, classify and declare anemergency condition within 15minutes after theavailability ofindications toplant operators thatanemergency action level hasbeen exceeded andtopromptly declare the emergency condition assoonaspossible ilallowing identification ofthe appropriate emergency classification level.TheNRCstaff hasprovided guidance onimplementing this requirement inNSIR/DPR-lSG-01,Interim Staff Guidance, Emergency Planning for Nuclear Power Plants (ref.4.I.9).
| |
| Whenassessing anEAI that specitles a time duration for the off-normal condition,the "clock" for theEAl time duration runs concurrently with the emergency classificationprocess "clock."
| |
| 3.I.2 Valid Indications AIIemergency classification assessments shall bebased upon valid indications,reportsor conditions. A valid indication, report, orcondition, isonethat hasbeen verifiedthrough appropriate 9 of262
| |
| | |
| PVNGS EMERGENCY PlAN REVISION69 PAGE131OF383 means suchthat there isnodoubt regarding the indicator's operability, the condition's existence, or thereport's accuracy. For example, verification could beaccomplished through aninstrument channel check, response onrelated orredundant indicators, ordirect observation byplant personnel.
| |
| Thevalidation ofindications should becompleted inamanner thatsupports timely emergency declaration.
| |
| 3.1.3 Imminent Conditions ForICsandEAIsthat have a stipulated timeduration (e.g., 15minutes, 30minutes, the etc.),
| |
| Emergency Coordinator should not wait untilthe applicable time haselapsed,but should declare the event assoonasit isdetermined that the condition has exceeded, orwilllikelyexceed, the applicable time. Ifanongoing radiological releaseis detected andthe release starttime is unknown, itshould beassumed that the releaseduration specified inthe IC/EAl hasbeen e xceeded, absent data tothe contrary.
| |
| 3.1.4 Planned vs.Unplanned Events A planned work activity that results inanexpected event orcondition which meetsorexceeds an EAl. does notwarrant anemergency declaration provided that: 1) theactivityproceeds asplanned and2)the plant remains within the limits imposed bythe operating license. Such activities include planned workto manipulate, test, repair, maintain ormodify a system orcomponent. Inthese cases, the controls associated with the planning, preparation andexecution of thework will ensure that compliance ismaintained with all aspects operating provided of the license thatt he activity proceeds and concludes as expected. Events or conditions of this typemay be subject tothe reporting requirements of10CFR50.72 4.1.4).
| |
| (ref.
| |
| 3.1.5 Classincation Based onAnalysis Theassessment ofsomeEAIsis based onthe results ofanalyses that arenecessary toascertain whether a specific EAl threshold has been exceeded (e.g.,dose assessments, chemistry sampling, RCSleak ratecalculation, etc.). Forthese EAIs,the EAlwording orthe associated basis discussion willidentify the necessary analysis. Inthese cases, the15-minute declaration period startswith theavailability ofthe analysis resultsthat showthe threshold tobeexceeded (i.e.,thisis the time that the EAl information isfirst available). TheNRCexpects licensees toestablish the capability toinitiate andcomplete EAl-related analyses within a reasonableperiod oftime (e.g.,
| |
| maintain the necessary expertise on-shift).
| |
| 3.1.6 Emergency Coordinator Judgment While the EAl.s have been developed toaddress a full spectrum ofpossibleevents andconditions which maywarrant emergency classification, aprovision for classificationbased on operator/management experience andjudgment isstill necessary. TheNEl99-01 EAlscheme 10of262
| |
| | |
| PVNGS EMERGENCY PIAN REVISION69 PAGE132OF383 provides the EmergencyCoordinator with the ability toclassify events andconditions based upon judgment usingEAI.s that areconsistent with the Emergency Classification Level (ECL) definitions (refer toCategory II). TheImergency Coordinator will need todetermine ifthe effects orconsequences ofthe event orcondition reasonably meetorexceed a particular EC1definition. A similar provision isincorporated inthe Fission Product Barrier Tables; judgment maybeused to determine the status ofa fissionproduct barrier.
| |
| 3.2 Classification Methodology Tomakeanemergency classitleation, the user will compare aneventorcondition the (i.e., relevant plant indications andreports) to an EAI (s) anddetermine ifthe EALhasbeen metorexceeded.
| |
| Theevaluation ofanIAl mustbeconsistent with the relatedOperating ModeApplicability and Notes. IfanEAI hasbeen metorexceeded, the associated ICis likewise met,the emergency classification process "clock" starts andthe ECL mustbedeclared inaccordance with plant procedures nolater than fifteen minutes after the process "clock" started.
| |
| Whenassessing anEALthat specitles a time duration forthe off-normal condition, the "elock" for the EAltime duration runs concurrently with the emergency elassification process "clock."For a full discussion ofthis timing requirement, refer toNSIR/DPR-ISG-01 (ref.4.I.9).
| |
| 3.2.1 Classilleation ofMultiple Events andConditions Whenmultiple emergency events orconditions arepresent, the userwill identify all metor exceeded EAl s. The highest applicable ECL identitled isdeclared. For example:
| |
| * If anAlert IAl. anda Site Area Imergency EAIaremet,whether at one unitorattwo differenta Site units, AreaEmergency should bedeclared.
| |
| There isno"additive" effect from multiple EAl.s meeting the sameECL.Forexample:
| |
| * IftwoAlert EAlsare met,whether atoneunit orattwodifferent units. anAlert should be declared.
| |
| Related guidance concerning classification ofrapidly escalating events orconditions isprovided in Regulatory Issue Summary (RIS) 2007-02, Clarification ofNRCGuidance for Emergency Notifications During Ouicidv Changing Events (ref. 4.I.2).
| |
| 3.2.2 Consideration ofModeChanges During Classification Themodeineffect atthe time that aneventorcondition occurred andprior toanyplant oroperator response, isthe modethat determines whether ornotanICis applicable. aneventorcondition If occurs andresults ina modechange before the emergency isdeclared, the emergency classification level isstill based onthe modethat existedatthe time that theeventorcondition wasinitiated (and IIof262
| |
| | |
| PVNGS EMERGENCY PlAN REVISION 69 PAGE133OF383 not when itwasdeclared). Oncea different modeisreached, anyneweventorcondition, not related tothe original event orcondition, requiringemergency classification shouldbeevaluated against the ICsandEAIsapplicable tothe operating modeatthe time ofthe neweventor condition.
| |
| Forevents thatoccur in Cold Shutdown orRefueling, escalation isvia EAl.s thatareapplicable in the Cold Shutdown or Refueling modes, evenifIlot Shutdown (or ahigher mode) isentered during the subsequent plant response. Inparticular,the fission product barrier EAl.s areapplicable onlyto events thatinitiateintheIlot Shutdown modeorhigher.
| |
| 3.2.3 Classil1cationofImminent Conditions Although EAI,sprovide specille thresholds, the Emergency Coordinator mustremain alert toevents orconditions thatcould lead tomeetingor exceeding anEAIwithin a relativelyshortperiod of time achange (i.e., inthe ECLisIMMINENT). If,inthe judgment ofthe Emergency Coordinator, meeting anEALis IMMINENT, the emergency classification should bemadeasif the EALhas been met.While applicable toall ECLs, thisapproach is particularly important atthehigher emergency classification levels since it provides additional timefor implementation of protective measures.
| |
| 3.2.4 Emergency Classification Ievel Upgrading andDowngrading An ECLmaybedowngraded whenthe event orcondition that meetsthe highest ICand EAIno longer existsand other site-specific downgrading requirements downgrading the are met. If ECIis deemed appropriate,the newECLwould thenbebased ona lower applicable IC(s) and EAL(s).
| |
| TheECImayalso simply be terminated.
| |
| Asnoted above, guidance concerning classification ofrapidly escalating eventsorconditions is provided inRIS2007-02 (ref. 4.I.2).
| |
| 3.2.5 Classit1cationofShort-I ived Events Event-based ICsandIAlsdefine a variety ofspecine occurrences that have potential oractual safety significance.Bytheir nature, someofthese events maybeshort-lived and,thus,over before the emergency classification assessment canbecompleted. If anevent occurs thatmeetsorexceeds anEAL,the associated ECLmustbedeclared regardless ofits continued atthe presence time of declaration. Examples ofsuch events include anearthquake ora failure ofthe protection reactor system toautomatically trip the reactor followed bya successful manual trip.
| |
| 3.2.6 ClassificationofTransient Conditions Manyofthe ICsand/or EALsemploy time-based criteria. These criteria willrequirethat the IC/EAI conditions bepresent fora defined period oftime before anemergency declaration is I2of262
| |
| | |
| PVNGS EMERGENCY PlAN REVISION69 PAGE134OF383 warranted. Incases where notime-based criterion isspecified, itisrecognized that sometransient conditions maycause anEAltobemet for abrief period oftime (e.g.,a fewseconds toa few minutes). The following guidance should beapplied tothe classilleationofthese conditions.
| |
| Ininstanceswhere anEAl isbriefly met during anexpected (normal) plant response, anemergency declaration isnotwarranted provided that associated systems andcomponents areoperating asexpected andoperator actions are performed inaccordance with procedures.
| |
| Ifan operator takes prompt manualaction toaddress acondition andthe action issuccessful incorrecting the condition prior tothe emergency declaration, then the applicable EALis notconsidered metand the associated emergency declarationis not required. Forillustrative purposes, consider the following example:
| |
| AnATWSoccurs andthe high pressureECCS systems fiiil toautomatically start. Reactor vessel level rapidly decreases andthe plant enters aninadequate core cooling condition (a potential loss ofboth the fuel clad andRCSbarriers). Ifanoperator manually starts ahigh pressure ECCSsystem inaccordance with anEOP step andclears the inadequate core cooling condition priortoanemergency declaration, then the classification should bebased onthe ATWSonly.
| |
| Itisimportant tostress thatthe15-minute emergency elassification assessment period (process clock) isnota"grace period" during which aclassification maybedelayed to allow the performance ofa corrective actionthat would obviate the need toclassify the event. Emergency classification assessments mustbedeliberate andtimely, with noundue delays.The provision discussed above addresses onlythose rapidly evolving situationswhenanoperatoris able totake a successful corrective action tothe prior Emergency Coordinator completing the review and steps necessary tomake the emergency declaration. This provision isincluded toensure thatany public protective actions resulting from the emergency classification aretruly warranted bythe plant conditions.
| |
| 3.2.7 After-the-Fact Discovery ofanEmergency Event orCondition Insomecases,anEAImaybemetbut the emergency classificationwasnotmade atthe time ofthe event orcondition. This situation canoccur whenpersonnel discover that aneventorcondition existed which metanEAl., but noemergency wasdeclared andthe event orcondition nolonger exists atthe time ofdiscovery. This maybeduetothe event orcondit:on notbeing recognized at the time oranerror thatwasmadeinthe emergency classification process.
| |
| Inthese cases,noemergency declaration iswarranted; however, theguidance contained in NUREG-1022 (ref. 4.I.3) isapplicable. Specifically, the event should bereported tothe NRCin 13of262

| With CONTAINMENT CIOSURE notestablished, there isa high potential fora direct and unmonitored release ofradioactivity tothe environment. IfCONTAINMENT ClOSUREis reestablished prior toexceeding the30-minute time limit, then declaration ofaGeneral Emergency isnotrequired.
| |
| Theexistence ofanexplosive mixture means, ata minimum, that the containment atmospheric hydrogen concentration issufficient tosupport a hydrogen burn (i.e.,atthe lower deflagration limit).A hydrogen burn willraise containment pressure and could result incollateral equipment damage leading toa loss ofcontainment integrity. Ittherefore represents a challenge to Containment integrity.
| |
| Inthe early stages ofa core uncovery event. it isunlikely that hydrogen buildup duetoacore uncovery could result inanexplosive gasmixture incontainment. lfall installed hydrogen gas monitors areout-of-service during anevent leading tofuel cladding damage, it maynotbepossible toobtain acontainment hydrogen gasconcentration reading asambient conditions within the containment will preclude personnel access. During periods wheninstalled containment hydrogen gasmonitors are out-of-service, operators mayusethe other listed indications toassesswhether or notcontainment ischallenged.
| |
| The30-minute criterion istied toa readily recognizable event start time (i.e.,thetotal lossofability tomonitor level) andallows sufncient time tomonitor, assess andcorrelate reactor and plant conditions todetermine ifcore uncovery has actually occurred (i.e..toaccount for various accident progression andinstrumentation uncertainties). also It allows sufficient time forperformance of actions toterminate leakage, recover inventory control/makeup equipment and/or restore level monitoring.

| Thetime interval isbased onhow quickly control mustbereestablished without core uncovery and/or core damage. Thedetermination ofwhether ornotcontrol isestablished from outside the Control Roomis based onEmergency Coordinator judgment. TheEmergency Coordinator is expected tomake a reasonable. informedjudgment that control ofthe plant from outside the Control Roomcannot beestablished withinthe 15minute interval.

| Oncethe Control Roomis evacuated. the objective is toestablish control ofimportant plant equipment andmaintain knowledge ofimportant plant parameters ina timely manner. Primary emphasis should beplaced oncomponents andinstruments that supply protection forand information about safety functions.Typically, these safety functions are reactivity control (ability to shutdown the reactor andmaintain it shutdown), RCSinventory (ability tocool the core) and secondary heat removal (ability tomaintain a heat sink).
| |
| This ICaddresses anevacuation ofthe Control Roomthat results intransfer ofplantcontrol to alternate locations andthe control ofa keysafety function cannot bereestablished ina timely manner.

This concept reliesonmultiple physicalbarriersanyoneofwhich, ifmaintained intact, precludes the release ofsignificant amounts ofradioactiveEssion products tothe environment. Theprimary fissionproduct barriers are:

| C.ContainmentiC.FMD TheContainment l3arrier includes thecontainment building and connections uptoandincluding the outermost containment isolation valves. This barrier alsoincludes the main steam,feedwater andblowdown lineextensions outside the containment building uptoandincluding the outermost secondary side isolation valve.
| |
| Containment 13arrier thresholds areused ascriteria for escalation of the ECI from Alert toa Site AreaEmergency oraGeneral Emergency.
| |
| TheEALsinthis category require evaluation ofthe loss andpotential loss thresholds listed in the Essionproduct barrier matrix ofTable F-1(Attachment 2). "Loss" and"Potential Loss" signify the damage relative andthreat ofdamage tothe barrier. "Loss" means thebarrier nolonger assures containmentofradioactive materials. "Potential 1.oss" meansintegrity ofthe barrieristhreatened andcould belost if conditions continue todegrade.

| PVNGS EMERGENCY PlAN REVISION 69 PAGE320OF383 ATTACIIMENT I EAlTechnical Bases Thelogic used for emergency classification based onilssion product monitoring barrier should renectthe following considerations:
| |
| * TheFuelClad Barrier andthe RCSBarrier areweighted moreheavily than the Containment Barrier.
| |
| a Unusual Event ICsassociated with RCSandFuel Clad Barriersareaddressed under System Malfunction ICs.
| |
| * Foraccident conditions involving a radiological release,evaluationofthe fission product barrier thresholds will need tobe performed inconjunction with doseassessments toensure correct andtimely escalation oftheemergency classification. Forexample, anevaluation of the fission product barrier thresholds may result in a SiteArea Emergency classification while adose assessment mayindicate thatan EAl. for General Emergency ICRG1has been exceeded.
| |
| a Thefission product barrier thresholds specifled within a scheme renect plant-specific PVNGSdesign andoperating characteristics.
| |
| * Asused inthis category, the termRCSleakage encompassesnot just those types defined in Technical Specifleations but alsoincludes the loss ofRCSmassto any location- inside the containment. aninterfacing system, oroutside ofthe containment.The release ofliquid or steammassfrom the RCSduetothe as-designed/expected of a relief valve operation isnot considered tobeRCSleakage.
| |
| * Atthe Site Area1mergency level,EAIusers should maintain cognizance ofhow far present conditions are from meeting athreshold that would requireaGeneral Emergency declaration. For example, ifthe 1uel Clad andRCSfission productbarriers werebothlost, then there should befrequent assessments ofcontainment inventory radioactive and integrity. Alternatively, if both theFuel Clad andRCSfission productbarriers were potentially lost,the Emergency Coordinator would havemoreassurance that there wasno immediate need toescalate toaGeneral Emergency.

Thetable isstructured so that each ofthe threebarriers occupies adjacent columns.Each fission product barrier column is further divided into twocolumns; onefor thresholds 1.oss andonefor Potential Iossthresholds.
| |
| Theilrst column ofthe table(to the leftofthe FuelCladIosscolumn) lists the categories (types) of tission product barrier thresholds. The lission productbarrier categories are:
| |
| A. RCSorSGTube Leakage B. Inadequate Heat Removal C. CTMTRadiation /RCSActivity D.CTMTIntegrity orBypass E. Emergency Coordinator Judgment Each category occupies arowinTable F-Ithus formingamatrix dellned bythe categories. The intersection ofeach rowwith each Ioss/PotentialIosscolumn forms acell inwhich oneormore fission product barrier thresholds appear. lfNEl99-01 doesnotdefine a threshold for a barrier Ioss/Potential Ioss,the cellisleft blank, shaded orotherwise indicated asnothaving a threshold associated with it.
| |
| Thresholds areassigned sequential numbers withineachIossandPotential Ioss column beginning with number one. Inthis manner, a threshold canbeidentified byits category title and number. For example, the firstFuel Clad barrier IossinCategory C would beassigned "FCIossC.I," the third Containment barrier Potential IossinCategory D wouldbeassigned "CTMTP-Loss D.3," etc.
| |
| If a cell inTable F-Icontains morethan onenumbered threshold, each ofthe numbered thresholds, if e xceeded, signifles a IossorPotential Iossofthe barrier.
| |
| Itis notnecessary toexceed all ofthe thresholds ina category before declaring abarrierLoss/Potential Ioss.
| |
| Subdivision ofTable F-Ibycategory facilitates association ofplant conditions tothe applicable fission product barrier Loss andPotential Iossthresholds.
| |
| This structure promotes a systematic approach toassessing the classificationstatusofthe product fission barriers.
| |
| Whenequipped with knowledge ofplant conditions relatedtothe fission product barriers, the EAl -
| |

| |
| = UNISOLABLE pathway from Containment tothe environment exists Definition(s):
| |
| UN/SOLABLEAn open orbreached system line that cannot beisolated. remotely orlocally.
| |
| Basis:
| |
| Containment isolations areinitiated bythe Containment Isolation Actuation System (CIAS) in response toa high containment pressure signal orlowpressurizerpressure belowthe SIASsetpoint (ref.I,2).
| |
| A penetration isconsidered isolated with atleast onecontainment isolationvalve closed. This may include a check valveifthere isnoindication that ithasfailed toclose.
| |
| These thresholds addressa situation where containment isolation isrequired andoneof two conditions exists asdiscussed below. Users arereminded that theremaybeaccident and release conditions thatsimultaneously meetboth bulleted thresholds.
| |
| FirstThreshold -
| |
| Containment integrity has been lost,i.e., the actualcontainment atmospheric leak ratelikely exceeds that associated with allowable leakage (or sometimes toasdesign referred leakage). Following therelease ofRCSmassinto containment, containment pressure will fluctuate based onavariety of factors; a loss ofcontainment integrity condition may(or maynot) be accompanied bya noticeable drop incontainment pressure. Recognizing theinherent difficulties in determining a containment leak rate during accident conditions. itisexpected thatthe Emergency Coordinator will assessthisthreshold using judgment andwith dueconsideration given tocurrent plant conditions andavailable operational andradiological data (e.g.containment pressure, readings onradiation monitors outside containment. operating statusofcontainment pressure control equipment, etc.).

| PVNGS EMERGENCY PlAN REVISION 69 PAGE365OF383 ATTACIIMENT 2 Iission Product Barrier1oss/Potential IossMatrix andBases Refer tothe middle piping runofFigure 1.Two simplilled examples areprovided. Oneis leakage from apenetration andthe other isleakage from anin-service system valve. Depending upon radiationmonitor locations and sensitivities,theleakage could bedetected byanyofthe four monitors depictedin the figure.
| |
| Another example wouldbe a lossorpotential lossofthe RCSbarrier andthe simultaneous occurrence oftwo FAULTED locations ona steamgenerator where onefault islocated inside containment (e.g.,
| |
| ona steamor feedwater line) andthe other outside ofcontainment. Inthis case, theassociated steamline providesa pathway for the containment atmosphere toescape toanarea outside thecontainment.
| |
| Following the leakage ofRCSmassinto containment anda rise incontainment pressure, there may beminor radiological releasesassociated withallowable (design)containment leakage through various penetrations orsystem components. These releases donotconstitute a loss orpotential loss ofcontainment but should beevaluated using theRecognition Category R ICs.
| |
| Second Threshold -
| |
| Conditions aresuch that there isanUNISOl ABl.E pathway for the migration ofradioactive material from thecontainment atmosphere tothe environment. Asused here, the term "environment" includes the atmosphere ofaroomorarea, outside the containment, that may, in turn,communicate with the outside-the-plant atmosphere (e.g.,through discharge of a ventilation system oratmospheric leakage).Depending upon avariety offactors, this condition mayormaynot beaccompanied bya noticeable drop incontainment pressure.
| |
| Refer tothe toppiping runofFigure 1 Inthis simplified example, the inboard and outboard isolationvalves remained open afteracontainment isolationwasrequired (i.e., containment isolationwasnotsuccessful). There isnowanUNISOI ABIE pathway from the containment tothe environment.
| |
| Theexistence ofa illterisnotconsidered inthe threshold assessment. Filters donotremove fission product noble gases. Inaddition,a illter could become ineffective duetoiodine and/or particulate loading beyond design limits retention (i.e., ability hasbeen exceeded) orwater saturation from steam/high humidity intherelease stream.
| |
| Ieakage between twointerfacing liquidsystems, byitself, does notmeetthis threshold. There must bearelease involved toatmosphere orinto another plant structure outside ofContainment.
| |
| Refer tothe bottom piping runofFigure 1 Inthis simplified example, leakage inanRCPseal cooler isallowing radioactive material toenter the AuxiliaryBuilding. The radioactivity would be detected bythe Process Monitor. Ifthere isnoleakage from the closed water cooling system tothe Auxiliary Building oratmosphere, then nothreshold has been met.

Ifthe fuel cladbarrier hasnotbeen lost,radiation monitor readings outside ofcontainment maynotincrease significantly: however, other unexpected changes insump levels, area temperatures orpressures, flow rates, etc. should besuf0cient todetermine ifRCSmass isbeing lost outside ofthe containment.
| |
| Refer tothe middle piping runofFigure I Inthissimplined example,a leak hasoccurred ata reducer ona pipe carrying reactor coolant inthe Auxiliary Building. Depending upon radiation monitor locations andsensitivities, the leakage could bedetected byanyofthe four monitors depicted inthe figure andcause threshold D.1tobemetaswell.

The radioactivity would bedetected bythe Process Monitor. If the Nuclear Cooling System (NC) pump developed a leakthat allowed steamAvater toleak toatmosphere, then this threshold ismet.
