Ow.,r+, Grzup+A-4 APPENDIX B -DEFINITIONS The following definitions are taken from Title 10, Code of Federal Regulations, and related regulatory guidance documents.
General Emergency:
Events are in progress or have occurred which involve actual or IMMINENT substantial core degradation or melting with potential for loss of containment integrity or HOSTILE ACTION that results in an actual loss of physical control of the facility.Releases can be reasonably expected to exceed EPA PAG exposure levels offsite for more than the immediate site area.Site Area Emergency:
Events are in progress or have occurred which involve actual or likely major failures of plant functions needed for protection of the public or HOSTILE ACTION that results in intentional damage or malicious acts; I) toward site personnel or equipment that could lead to the likely failure of or; 2) that prevent effective access to, equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA PAG exposure levels beyond the site boundary.Alert: Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION.Any releases are expected to be limited to small fractions of the EPA PAG exposure levels.Notification of Unusual Event (NOUE): Events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated.
No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.The following are key terms necessary for overall understanding the NE1 99-01 emergency classification scheme.Emergency Action Level (EAL): A pre-determined, site-specific, observable threshold for an Initiating Condition that, when met or exceeded, places the plant in a given emergency classification level.Emergency Classification Level (ECL): One of a set of names or titles established by the US Nuclear Regulatory Commission (NRC) for grouping off-normal events or conditions according to (1) potential or actual effects or consequences, and (2) resulting onsite and offsite response actions. The emergency classification levels, in aseendifig order of severity, are: General Emergency (GE)Site Area Emergency (SAE)Alert Notification of Unusual Event (NOUE)Fission Product Barrier Threshold:
A pre-determined, site-specific, observable threshold indicating the loss or potential loss of a fission product barrier.Initiating Condition (IC): An event or condition that aligns with the definition of one of the four emergency classification levels by virtue of the potential or actual effects or consequences.
B-I Selected terms used in Initiating Condition and Emergency Action Level statements are set in all capital letters (e.g., ALL CAPS). These words are defined terms that have specific meanings as used in this document.
The definitions of these terms are provided below.CONFINEMENT BOUNDARY:

A rapid, violent and catastrophic failure of a piece of equipment due to combustion, chemical reaction or overpressurization.
A release of steam (from high energy lines or components) or an electrical component failure (caused by short circuits, grounding, arcing, etc.) should not automatically be considered an explosion.
Such events may require a post-event inspection to determine if the attributes of an explosion are present.FAULTED: The term applied to a steam generator that has a steam leak on the secondary side of sufficient size to cause an uncontrolled drop in steam generator pressure or the steam generator to become completel depressurized.
Devclopcr N-te Thiso term ic -pliae t......nly 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 flame is preferred but is NOT required if large quantities of smoke and heat are observed.HOSTAGE: A person(s) held as leverage against the station to ensure that demands will be met by the station.HOSTILE ACTION: An act toward a nuclear pox.cr plant INPP) or its personnel that includes the use of violent force to destroy equipment, take HOSTAGES, and/or intimidate the licensee to achieve an end. This includes attack by air, land, or water using guns, explosives, PROJECTILEs, vehicles, or other devices used to deliver destructive force. Other acts that satisfy the overall intent may be included.
HOSTILE ACTION should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the NPP. Non-terrorism-based EALs should be used to address such activities (i.e., this may include violent acts between individuals in the owner controlled area tO(A)).HOSTILE FORCE: One or more individuals who are engaged in a determined assault, overtly or by stealth and deception, equipped with suitable weapons capable of killing, maiming, or causing destruction.
IMMINENT:
The trajectory of events or conditions is such that an EAL will be met within a relatively short period of time regardless of mitigation or corrective actions.INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI): A complex that is designed and constructed for the interim storage of spent nuclear fuel and other radioactive materials associated with spent fuel storage.B-2 t;;enrty fc'/.r hc-..: 'clu7."ding the .cuar, cnt pe-ek ;'olte.OWNER CONTROLLED AREA t(OCA: b he area that encompasses all controlled areas '\ ithin the NI:N site boundary but outs ide the seeurity protectedl area fencc(ne., ....t....... i defin'iticn for De, .... ,^ e.,t^, Thi: t... ic; typizally take+n t.....n the cit .........by, Cr' ct~her+:;,'iee under. +th ....... ef the liaer;......

[Refer to Appendix 1, Emergency Action Level Guidelines for Nuclear Power Plants]NUREG-1022, Event Reporting Guidelines 10 CFR § 50. 72 and§ 50. 73 Regulatory Guide 1.101, Emergency Response Planning and Preparedness for Nuclear Power Reactors'lhis list is not all-inclusive.
a*m4i4--ll is strongly recommended that scheme developers consult with licensing and regulatory compliance personnel to identify and understand all applicable requirements and guidance.
Questions may also be directed to the NEI Emergency Preparedness staff.1.2 INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)Selected guidance in NEI 99-01 is applicable to licensees electing to use their 10 CFR 50 emergency plan to fulfill the requirements of 10 CFR 72.32 for a stand-alone ISFSI. The emergency classification levels applicable to an ISFSI are consistent with the requirements of 10 CFR § 50 and the guidance in NUREG 0654/FEMA-REP-1.
The initiating conditions germane to a 10 CFR § 72.32 emergency plan (as described in NUREG-1567) are sub~iffe4-contained within the classification scheme for a 10 CFR §50.47 emergency plan.The generic ICs and EALs for an ISFSI are presented in Section 85, ISFSI ICs/EALs.

NUREG-1 140 concluded that the postulated worst-case accident involving an ISFSI has insignificant consequences to public health and safety. This evaluation shows that the maximum offsite dose to a member of the public due to an accidental release of radioactive materials would not exceed I rem Effective Dose Equivalent.

.......e Organization (EROf, 1.3 NRC ORDER EA-12-051 The Fukushima Daiichi accident of March 11, 204-.2i' It, was the result of a tsunami that exceeded the plant's design basis and flooded the site's emergency electrical power supplies and distribution systems. This caused an extended loss of power that severely compromised the key safety functions of core cooling and containment integrity, and ultimately led-Ieadirag to core damage in three reactors.
Zh-i4e-Altthough the loss of power also impaired the spent fuel pool cooling function, sufficient water inventory was maintained in the pools to p~'eehe-prcvcnt fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that sei'efa measures were necessary to ensure adequate protection of public health and safety under the provisions of the backfit rule, 10 CFR 50.109(a)(4)(ii).
A~mong them t... proi O.ne such meaure v~as that each spent fuel pool he pra ided with reliable level instrumentation to significantly enhance the ability of key decision-makers to allocate resources e..ec.ive~y-following a beyond design basis event. To this end, the NRC issued Order EA- 12-051, Issuance of Order to Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation, on March 12, 2012, to all US nuclear plants with an operating license, construction permit, or combined construction and operating license.NRC Order EA-12-05 1 states, in part, "All licensees
... shall have a reliable indication of the water level in associated spent fuel storage pools capable of supporting identification of the following pool water level conditions by trained personnel:
(1) level that is adequate to support operation of the normal fuel pool cooling system, (2) level that is adequate to provide substantial radiation shielding for a person standing on the spent fuel pool operating deck, and (3) level where fuel remains covered and actions to implement 2 make-up water addition should no longer be deferred." Te thise.ei,-All licensees must ihcr~clorc provide:* A primary and back-up level instrument that will monitor water level from the normal level to the top of the used fuel rack in the pool,.* A display in an area accessible following a severe event;--atd.
- Independent electrical power to each instrument channel and pi'e4de-an alternate remote power connection capability.
NEI 12-02, Industry Guidance for Compliance with NRC Order EA-12-051, "To Modif Licenses with Regard to Reliable Spent Fuel Pool Instrumentation
", provides guidance for complying with NRC Order EA- 12-051.NEI 99-01, Revision 6, includes three EALs that reflect the availability of the enhanced spent fuel pool level instrumentation associated with NRC Order EA- 12-051. These EALs are included within existing IC RA2, and new ICs RS2 and RG2. Associated EAL notes, bases and developer notes are also provided.It is recommended that these EALs be implemented when the enhanced spent fuel pool level instrumentation is available for use.The regulatory process that licensees follow to make changes to their emergency plan, including non-scheme changes to EALs, is 10 CFR 50.54(q).

Frz~iu~ntlv Azkzd Qu~,tionc prc~c~.20 52 GUIDANCE ON MAKING EMERGENCY CLASSIFICATIONSI GENERAL CONSIDERATIONS Wrhf.tk .. .i..g"-e nior any. emergency classification, the emergency director must consider all information having a bearing on the proper assessment of an initiating condition (IC).This includes the emergency action level (EAL). l+is-the associated operating mode applicability, notes. and the informing basis information.
In the recognition category F matrices, EALs are referred to as fission product barrier thresholds; the thresholds serve the same function as an EAL.NRC regulations require the licensee to establish and maintain the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indications to plant operators that an emergency action level has been exceeded and to promptly declare the emergency condition as soon as possible following identification of the appropriate emergency classification level. The NRC staff has provided guidance on implementing this requirement in NSIR/DPR-ISG-0 1, Interim Staff Guidance, Emergency Planning for Nuclear Power Plants.All emergency classification assessments soeid-4x ill be based **pon valid indications, reports or conditions.
A valid indication, report, or condition, :i oei eha4-has been verified Ohfe-*gh-using appropriate means. su.ch t~hat there :altar ing no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.
For example, validation could be aeeempliched through an instrument channel check, response on related or redundant indicators, or direct observation by plant personnel.
The validateien ofindications she*14d-\ilI be ... ...in a manner that supports timely emergency declaration.
For ICs and EALs that have a stipulated time duration (e.g., I.S 30..
eta.), the emergency director shudwitl not wait until the applicable time has elapsed, but sheel4-will declare the event as soon as it is determined that the condition has exceeded, or will likely exceed, the applicable time. If an ongoing radiological release is detected and the release start time is unknown, it sheu4d-wiIl be assumed that the release duration specified in the IC/EAL has been exceeded, absent data to the contrary.A planned work activity that-reeultsresultin2, in an expected event or condition which meets or exceeds an EAL does not warrant an emergency declaration provided that 1) the activity proceeds as planned and 2) the plant remains within the limits imposed by the operating license. Such activities include planned work to test, manipulate, repair, maintain or modify' a system or component.
In +these-such cases, the controls associated with the planning, preparation and execution of the work will ensure thaI-compliance with the opcratiflg license is maintained, with all" aspect ... f the operating license provided thaI-the activity proceeds and concludes as expected.
Events or conditions of this type may be subject to the reporting requirements of 10 § CFR 50.72.Th...........men.
f Some EALs is-arc assessed based on the results of analyses that-&e necessary to ascertain whether a specific EAL threshold has been exceeded-(erg.,,-aes a......m.n.., chemstr ........., tR-C leak. rata ealculatien, etc.);. The EAL and/or the associated basis discussion will identify the necessary analysis.
Iin these-ee, ;The 15-21 minute declaration period starts with the availability of the analysis results that show the threshold to be exceeded (i.e., this is the time that the EAL information is first available).
The NRC expects licensees to establish the capability to initiate and complete EAL-related analyses within a reasonable period of time (e.g., ................ no .......... -W-hi4e-Although the EALs have been developed to address a full spectrum of possible events and conditions which may warrant emergency classification, a provision for classification based on operator/management experience and judgment is still necessary.
The NEI 99-01 scheme provides the emergency director with the ability to classify events and conditions based upon judgment using EALs that are consistent with the emergency classification level (ECL) definitions (refer to Category H). The emergency director will need to determine if the effects or consequences of the event or condition reasonably meet or exceed a particular ECL definition.
A similar provision is incorporated into the fission product barrier tables; judgment may be used to determine the status of a fission product barrier.CLASSIFICATION METHODOLOGY To make an emergency classification, the user will compare an event or condition (i.e., the relevant plant indications and reports) to an EAL(s) and determine if the EAL has been met or exceeded.
Thez evaluation eflAn EAL(s) e~aluation must be consistent with the related operating mode applicability and notes. If an EAL has been met or exceeded, t-heft-the IC is eefriideared-met and the associated ECL is declared in accordance with plant procedures.
When assessing an EAL that specifies a time duration for the off-normal condition, the"clock" for the EAL time duration runs concurrently with the emergency classification process "clock." For a full discussion of this timing requirement, refer to NSIR/DPR-ISG-0I..¢,2.3 CLASSIFICATION OF MULTIPLE EVENTS AND CONDITIONS Wbhii-ln the cnt of multiple emergency-emcrlcncic., e,,e+&sor conditions-ae-pre~e44, the user will identify all met or exceeded EALs. The highest applicable ECL identified during this review is declared.
For example: If an Alert EAL and a Site Area Emergency EAL are met, whethar at one unit or at two,' different units, a Site Area Emergency ill be declared.There is no "additive" effect from multiple EALs meeting the same ECL. For example: If two Alert EALs are met, wh"ther " ...n... uni or ..t. tzo +- .i..r.n unit', an Alert should-\ ill be declared.Related guidance concerning classification of rapidly escalating events or conditions is provided in Regulatory Issue Summary (RIS) 2007-02, Clarification of NRC Guidance for Emergency Notifications During Quickly Changing Events.22 CONSIDERATION OF MODE CHANGES DURING CLASSIFICATION-The mode in effect at the time that an event or condition occurred, and prior to any plant or operator response, is the mo~de that dletermines whether et-eta IC is applicable.
If an event or condition occurs; and results in a mode change before the emergency is declared, the emergency classification level is still based on the mode that existed at the time that the event or condition was initiated (and not when it was declared).

If, in the judgment of the emergency director, meeting an EAL is IMMINENT, the emergency classification should will be made as if the EAL has been met. While applicable to all emergency classification levels, this approach is particularly important at the higher emergency classification levels since it provides additional time for implementation of protective measures..-62.6 EMERGENCY CLASSIFICATION LEVEL UPGRADING AND DOWNGRADING SN(C poliex is that once an emergent?

Basis: This IC addresses a release of gaseous radioactivity that results in projected or actual offsite doses greater than or equal to the EPA Protective Action Guides (PAGs). It includes both monitored and un-monitored releases.
Releases of this magnitude will require implementation of protective actions for the public.27 Radiological effluent EALs are els~e-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.
I he monitor reading threshold values are determined using a dose assessment method that hack calculates from the dose \,alues specified in the IC. The meteorology and source term tnoble gases. particulates.
and halogens)used are the same as those used to determine the monitor reading threshold values in ICs RSI1 and RA !, This protocol will maintain inter\,als betxveen the threshold alues for the three classifications.
Since doses are generally not monitored in real-time.
a release duration of one hour is assumed, and the threshold values are based on a site boundary, (or beyond) dose of I1000)mR/hour whole body or 5(000 mR/hour thyroid, whichever is more limiting.The TEDE dose is set at the EPA PAG of 1,000 mrem while the 5,000 mrem thyroid CDE was established in consideration of the 1:5 ratio of the EPA PAG for TEDE and thyroid CDE.Classification based on effluent monitor readings assumes that a release path to the environment is established.
If the effluent flow past an effluent monitor is known to have stopped due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes..... eff+ luent l+.,-; A a... in....cl.a, :uded taroid ..... for clazifin ..... nte tha... can,-beradalyze in esified ran, the:azi , plant:, canditian lane.+ 1hz incluz:ian

Ow.,r+, Grzup+A-4 APPENDIX B -DEFINITIONS The following definitions are taken from Title 10, Code of Federal Regulations, and related regulatory guidance documents.
General Emergency:
Events are in progress or have occurred which involve actual or IMMINENT substantial core degradation or melting with potential for loss of containment integrity or HOSTILE ACTION that results in an actual loss of physical control of the facility.Releases can be reasonably expected to exceed EPA PAG exposure levels offsite for more than the immediate site area.Site Area Emergency:
Events are in progress or have occurred which involve actual or likely major failures of plant functions needed for protection of the public or HOSTILE ACTION that results in intentional damage or malicious acts; I) toward site personnel or equipment that could lead to the likely failure of or; 2) that prevent effective access to, equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA PAG exposure levels beyond the site boundary.Alert: Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION.Any releases are expected to be limited to small fractions of the EPA PAG exposure levels.Notification of Unusual Event (NOUE): Events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated.
No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.The following are key terms necessary for overall understanding the NE1 99-01 emergency classification scheme.Emergency Action Level (EAL): A pre-determined, site-specific, observable threshold for an Initiating Condition that, when met or exceeded, places the plant in a given emergency classification level.Emergency Classification Level (ECL): One of a set of names or titles established by the US Nuclear Regulatory Commission (NRC) for grouping off-normal events or conditions according to (1) potential or actual effects or consequences, and (2) resulting onsite and offsite response actions. The emergency classification levels, in aseendifig order of severity, are: General Emergency (GE)Site Area Emergency (SAE)Alert Notification of Unusual Event (NOUE)Fission Product Barrier Threshold:
A pre-determined, site-specific, observable threshold indicating the loss or potential loss of a fission product barrier.Initiating Condition (IC): An event or condition that aligns with the definition of one of the four emergency classification levels by virtue of the potential or actual effects or consequences.
B-I Selected terms used in Initiating Condition and Emergency Action Level statements are set in all capital letters (e.g., ALL CAPS). These words are defined terms that have specific meanings as used in this document.
The definitions of these terms are provided below.CONFINEMENT BOUNDARY:

taken tae cecu.re EXPLOSION:
A rapid, violent and catastrophic failure of a piece of equipment due to combustion, chemical reaction or overpressurization.
A release of steam (from high energy lines or components) or an electrical component failure (caused by short circuits, grounding, arcing, etc.) should not automatically be considered an explosion.
Such events may require a post-event inspection to determine if the attributes of an explosion are present.FAULTED: The term applied to a steam generator that has a steam leak on the secondary side of sufficient size to cause an uncontrolled drop in steam generator pressure or the steam generator to become completel depressurized.
Devclopcr N-te Thiso term ic -pliae t......nly 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 flame is preferred but is NOT required if large quantities of smoke and heat are observed.HOSTAGE: A person(s) held as leverage against the station to ensure that demands will be met by the station.HOSTILE ACTION: An act toward a nuclear pox.cr plant INPP) or its personnel that includes the use of violent force to destroy equipment, take HOSTAGES, and/or intimidate the licensee to achieve an end. This includes attack by air, land, or water using guns, explosives, PROJECTILEs, vehicles, or other devices used to deliver destructive force. Other acts that satisfy the overall intent may be included.
HOSTILE ACTION should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the NPP. Non-terrorism-based EALs should be used to address such activities (i.e., this may include violent acts between individuals in the owner controlled area tO(A)).HOSTILE FORCE: One or more individuals who are engaged in a determined assault, overtly or by stealth and deception, equipped with suitable weapons capable of killing, maiming, or causing destruction.
IMMINENT:
The trajectory of events or conditions is such that an EAL will be met within a relatively short period of time regardless of mitigation or corrective actions.INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI): A complex that is designed and constructed for the interim storage of spent nuclear fuel and other radioactive materials associated with spent fuel storage.B-2 t;;enrty fc'/.r hc-..: 'clu7."ding the .cuar, cnt pe-ek ;'olte.OWNER CONTROLLED AREA t(OCA: b he area that encompasses all controlled areas '\ ithin the NI:N site boundary but outs ide the seeurity protectedl area fencc(ne., ....t....... i defin'iticn for De, .... ,^ e.,t^, Thi: t... ic; typizally take+n t.....n the cit .........by, Cr' ct~her+:;,'iee under. +th ....... ef the liaer;......

NUREG-0654/FEMA-REP-1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, October 1980. [Refer to Appendix 1, Emergency Action Level Guidelines for Nuclear Power Plants]NUREG-1022, Event Reporting Guidelines 10 CFR § 50. 72 and§ 50. 73 Regulatory Guide 1.101, Emergency Response Planning and Preparedness for Nuclear Power Reactors'lhis list is not all-inclusive.
a*m4i4--ll is strongly recommended that scheme developers consult with licensing and regulatory compliance personnel to identify and understand all applicable requirements and guidance.
Questions may also be directed to the NEI Emergency Preparedness staff.1.2 INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)Selected guidance in NEI 99-01 is applicable to licensees electing to use their 10 CFR 50 emergency plan to fulfill the requirements of 10 CFR 72.32 for a stand-alone ISFSI. The emergency classification levels applicable to an ISFSI are consistent with the requirements of 10 CFR § 50 and the guidance in NUREG 0654/FEMA-REP-1.
The initiating conditions germane to a 10 CFR § 72.32 emergency plan (as described in NUREG-1567) are sub~iffe4-contained within the classification scheme for a 10 CFR §50.47 emergency plan.The generic ICs and EALs for an ISFSI are presented in Section 85, ISFSI ICs/EALs.

NUREG-1 140 concluded that the postulated worst-case accident involving an ISFSI has insignificant consequences to public health and safety. This evaluation shows that the maximum offsite dose to a member of the public due to an accidental release of radioactive materials would not exceed I rem Effective Dose Equivalent.

A o, ic...2...." Emergency;
.......e Organization (EROf, 1.3 NRC ORDER EA-12-051 The Fukushima Daiichi accident of March 11, 204-.2i' It, was the result of a tsunami that exceeded the plant's design basis and flooded the site's emergency electrical power supplies and distribution systems. This caused an extended loss of power that severely compromised the key safety functions of core cooling and containment integrity, and ultimately led-Ieadirag to core damage in three reactors.
Zh-i4e-Altthough the loss of power also impaired the spent fuel pool cooling function, sufficient water inventory was maintained in the pools to p~'eehe-prcvcnt fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that sei'efa measures were necessary to ensure adequate protection of public health and safety under the provisions of the backfit rule, 10 CFR 50.109(a)(4)(ii).
A~mong them t... proi O.ne such meaure v~as that each spent fuel pool he pra ided with reliable level instrumentation to significantly enhance the ability of key decision-makers to allocate resources e..ec.ive~y-following a beyond design basis event. To this end, the NRC issued Order EA- 12-051, Issuance of Order to Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation, on March 12, 2012, to all US nuclear plants with an operating license, construction permit, or combined construction and operating license.NRC Order EA-12-05 1 states, in part, "All licensees
... shall have a reliable indication of the water level in associated spent fuel storage pools capable of supporting identification of the following pool water level conditions by trained personnel:
(1) level that is adequate to support operation of the normal fuel pool cooling system, (2) level that is adequate to provide substantial radiation shielding for a person standing on the spent fuel pool operating deck, and (3) level where fuel remains covered and actions to implement 2 make-up water addition should no longer be deferred." Te thise.ei,-All licensees must ihcr~clorc provide:* A primary and back-up level instrument that will monitor water level from the normal level to the top of the used fuel rack in the pool,.* A display in an area accessible following a severe event;--atd.
- Independent electrical power to each instrument channel and pi'e4de-an alternate remote power connection capability.
NEI 12-02, Industry Guidance for Compliance with NRC Order EA-12-051, "To Modif Licenses with Regard to Reliable Spent Fuel Pool Instrumentation
", provides guidance for complying with NRC Order EA- 12-051.NEI 99-01, Revision 6, includes three EALs that reflect the availability of the enhanced spent fuel pool level instrumentation associated with NRC Order EA- 12-051. These EALs are included within existing IC RA2, and new ICs RS2 and RG2. Associated EAL notes, bases and developer notes are also provided.It is recommended that these EALs be implemented when the enhanced spent fuel pool level instrumentation is available for use.The regulatory process that licensees follow to make changes to their emergency plan, including non-scheme changes to EALs, is 10 CFR 50.54(q).

Frz~iu~ntlv Azkzd Qu~,tionc prc~c~.20 52 GUIDANCE ON MAKING EMERGENCY CLASSIFICATIONSI GENERAL CONSIDERATIONS Wrhf.tk .. .i..g"-e nior any. emergency classification, the emergency director must consider all information having a bearing on the proper assessment of an initiating condition (IC).This includes the emergency action level (EAL). l+is-the associated operating mode applicability, notes. and the informing basis information.
In the recognition category F matrices, EALs are referred to as fission product barrier thresholds; the thresholds serve the same function as an EAL.NRC regulations require the licensee to establish and maintain the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indications to plant operators that an emergency action level has been exceeded and to promptly declare the emergency condition as soon as possible following identification of the appropriate emergency classification level. The NRC staff has provided guidance on implementing this requirement in NSIR/DPR-ISG-0 1, Interim Staff Guidance, Emergency Planning for Nuclear Power Plants.All emergency classification assessments soeid-4x ill be based **pon valid indications, reports or conditions.
A valid indication, report, or condition, :i oei eha4-has been verified Ohfe-*gh-using appropriate means. su.ch t~hat there :altar ing no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.
For example, validation could be aeeempliched through an instrument channel check, response on related or redundant indicators, or direct observation by plant personnel.
The validateien ofindications she*14d-\ilI be ... ...in a manner that supports timely emergency declaration.
For ICs and EALs that have a stipulated time duration (e.g., I.S 30..
eta.), the emergency director shudwitl not wait until the applicable time has elapsed, but sheel4-will declare the event as soon as it is determined that the condition has exceeded, or will likely exceed, the applicable time. If an ongoing radiological release is detected and the release start time is unknown, it sheu4d-wiIl be assumed that the release duration specified in the IC/EAL has been exceeded, absent data to the contrary.A planned work activity that-reeultsresultin2, in an expected event or condition which meets or exceeds an EAL does not warrant an emergency declaration provided that 1) the activity proceeds as planned and 2) the plant remains within the limits imposed by the operating license. Such activities include planned work to test, manipulate, repair, maintain or modify' a system or component.
In +these-such cases, the controls associated with the planning, preparation and execution of the work will ensure thaI-compliance with the opcratiflg license is maintained, with all" aspect ... f the operating license provided thaI-the activity proceeds and concludes as expected.
Events or conditions of this type may be subject to the reporting requirements of 10 § CFR 50.72.Th...........men.
f Some EALs is-arc assessed based on the results of analyses that-&e necessary to ascertain whether a specific EAL threshold has been exceeded-(erg.,,-aes a......m.n.., chemstr ........., tR-C leak. rata ealculatien, etc.);. The EAL and/or the associated basis discussion will identify the necessary analysis.
Iin these-ee, ;The 15-21 minute declaration period starts with the availability of the analysis results that show the threshold to be exceeded (i.e., this is the time that the EAL information is first available).
The NRC expects licensees to establish the capability to initiate and complete EAL-related analyses within a reasonable period of time (e.g., ................ no .......... -W-hi4e-Although the EALs have been developed to address a full spectrum of possible events and conditions which may warrant emergency classification, a provision for classification based on operator/management experience and judgment is still necessary.
The NEI 99-01 scheme provides the emergency director with the ability to classify events and conditions based upon judgment using EALs that are consistent with the emergency classification level (ECL) definitions (refer to Category H). The emergency director will need to determine if the effects or consequences of the event or condition reasonably meet or exceed a particular ECL definition.
A similar provision is incorporated into the fission product barrier tables; judgment may be used to determine the status of a fission product barrier.CLASSIFICATION METHODOLOGY To make an emergency classification, the user will compare an event or condition (i.e., the relevant plant indications and reports) to an EAL(s) and determine if the EAL has been met or exceeded.
Thez evaluation eflAn EAL(s) e~aluation must be consistent with the related operating mode applicability and notes. If an EAL has been met or exceeded, t-heft-the IC is eefriideared-met and the associated ECL is declared in accordance with plant procedures.
When assessing an EAL that specifies a time duration for the off-normal condition, the"clock" for the EAL time duration runs concurrently with the emergency classification process "clock." For a full discussion of this timing requirement, refer to NSIR/DPR-ISG-0I..¢,2.3 CLASSIFICATION OF MULTIPLE EVENTS AND CONDITIONS Wbhii-ln the cnt of multiple emergency-emcrlcncic., e,,e+&sor conditions-ae-pre~e44, the user will identify all met or exceeded EALs. The highest applicable ECL identified during this review is declared.
For example: If an Alert EAL and a Site Area Emergency EAL are met, whethar at one unit or at two,' different units, a Site Area Emergency ill be declared.There is no "additive" effect from multiple EALs meeting the same ECL. For example: If two Alert EALs are met, wh"ther " ...n... uni or ..t. tzo +- .i..r.n unit', an Alert should-\ ill be declared.Related guidance concerning classification of rapidly escalating events or conditions is provided in Regulatory Issue Summary (RIS) 2007-02, Clarification of NRC Guidance for Emergency Notifications During Quickly Changing Events.22 CONSIDERATION OF MODE CHANGES DURING CLASSIFICATION-The mode in effect at the time that an event or condition occurred, and prior to any plant or operator response, is the mo~de that dletermines whether et-eta IC is applicable.
If an event or condition occurs; and results in a mode change before the emergency is declared, the emergency classification level is still based on the mode that existed at the time that the event or condition was initiated (and not when it was declared).

If, in the judgment of the emergency director, meeting an EAL is IMMINENT, the emergency classification should will be made as if the EAL has been met. While applicable to all emergency classification levels, this approach is particularly important at the higher emergency classification levels since it provides additional time for implementation of protective measures..-62.6 EMERGENCY CLASSIFICATION LEVEL UPGRADING AND DOWNGRADING SN(C poliex is that once an emergent?

Basis: This IC addresses a release of gaseous radioactivity that results in projected or actual offsite doses greater than or equal to the EPA Protective Action Guides (PAGs). It includes both monitored and un-monitored releases.
Releases of this magnitude will require implementation of protective actions for the public.27 Radiological effluent EALs are els~e-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.
I he monitor reading threshold values are determined using a dose assessment method that hack calculates from the dose \,alues specified in the IC. The meteorology and source term tnoble gases. particulates.
and halogens)used are the same as those used to determine the monitor reading threshold values in ICs RSI1 and RA !, This protocol will maintain inter\,als betxveen the threshold alues for the three classifications.
Since doses are generally not monitored in real-time.
a release duration of one hour is assumed, and the threshold values are based on a site boundary, (or beyond) dose of I1000)mR/hour whole body or 5(000 mR/hour thyroid, whichever is more limiting.The TEDE dose is set at the EPA PAG of 1,000 mrem while the 5,000 mrem thyroid CDE was established in consideration of the 1:5 ratio of the EPA PAG for TEDE and thyroid CDE.Classification based on effluent monitor readings assumes that a release path to the environment is established.
