OF EMERGENCY ACTION LEVELS 1 REGULATORY BACKGROUND 1.1 OPERATING REACTORS Title 10, Code of Federal Regulations (CFR), Energy, contains the U.S. Nuclear Regulatory Commission (NRC) regulations that apply to nuclear power facilities.

Several of these regulations govern various aspects of an emergency classification scheme. A-review -f-theTh relevant sections !Ibted belaw': will aid the reader in un............

th ..... te..........gy preyidead in Scti;on 3.0 offor this document are:,* 10 CFR § 50.47(a)(1)(i)

  • 10 CFR § 50.47(b)(4)
  • 10 CFR § 50.54(q)* 10 CFR § 50.72(a)* 10 CFR § 50, Appendix E, IV.B, Assessment Actions* 10 CFR § 50, Appendix E, IV.C, Activation of Emergency Organizationlhsce regulations are supplemented by va-ioieas-regulatory guidance documents.

44e-l)ocuments of particular relevance to NEI 99-01 eaei-miclude:

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 4-he-abve~elhis list is not all-inclusive.

wnd41t is strongly recommended that scheme developers consult with licensingLand regulatory compliance personnel to identify and understand all applicable requirements and guidance.

Questions say-also may 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 1 0 CFR § 50 and the guidance in NUREG 0654/FEMA-REP-I1.

The initiating conditions germane to a 10 CFR § 72.32 emergency plan (as described in NUREG-1 567) are e'ibs',med-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 ICsiEALs.

IC E-HU I covers the-speetrw:i-0f credible natural and man-made events included within the scope of an ISFSI design. This IC is not applicable to installations or facilities that *nay process and/or repackage spent fuel te.g., a Menier: .......

I-addieltrAdditionlaIlx, appropriate aspects of IC HUI and IC I-AlI shu4vill also be included to address a HOSTILE ACTION directed against an ISFSI.The analysis of potential onsite and offsite consequences of accidental releases associated with the operation of an ISFSI is contained in NUREG-l 1140, A Regulatory Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees.

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.

ith......

for The Fukushima Daiichi accident of March 11, 2-O42011 , 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, mtad ultimately led-Icadino to core damage in three reactors. -While-A ithouch the loss of power also impaired the spent fuel pool cooling function, sufficient water inventory was maintained in the pools to preelede-picx cnt fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that sevefa 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).

Amoang them to pfe4de)nc such meas~ure that each spent fuel pool be providcd with reliable level instrumentation to significantly enhance the ability of key decision-makers to ecl'cctix cily allocate resources effeetively-following a beyond design basis event. To this end, the NRC issued Order LA- 12-051!, Issuance of Order to Modif 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-12-051 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 make-up water addition should no longer be deferred." Toethi5 end, aAll licensees must t herc Iorc provide:* A primary and back-up level instrument that will monitor water level from the normal 2 level to the top of the used fuel rack in the pool..* A display in an area accessible following a severe event;-maid.

  • Independent electrical power to each instrument channel and p*e4ean alternate remote power connection capability.

NEI 12-02, Industry Guidance for Compliance with NRC Order EA-12-051, 'To Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation

", provides guidance for complying with NRC Order EA-12-051I.

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-12-05 1. 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).

In accerdance

with thi'&reguileae!4, !,icensees are responsible for evaluating a proposed change and determining whether or not it results in a reduction in the plan>'s effectiveness-ef the-pl=n.

............

g-, ..Ior an'. 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). pkls-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 s-eIuld-w ill be based uipon valid indications, reports or conditions.

A valid indication, report, or condition, ne that-has been verified appropriate means. uhta ............

bIet in no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.

For example, validation could be thrc-gh an instrument channel check, response on related or redundant indicators, or direct observation by plant personnel.

h e4 !ndications be ..... p .... vahdldtcd in a manner that supports timely emergency declaration.

For ICs and EALs that have a stipulated time duration (e.g., 15 ......,.3.........,........

, the emergency director sh ld-.I not wait until the applicable time has elapsed, but shudwill 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 shu4will be assumed that the release duration specified in the IC/EAL has been exceeded, absent data to the contrary.A planned work activity #ht-vet....

....... s tlsrlting in an expected event or condition whieho-tlhal 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 t4iesesuelh cases, the controls associated with the planning, preparation and execution of the work will ensure *4hat-compliance wsith the opetating license is maintained, with all acpcctc of the pecrazting licence provided t-It-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.The asceccment ,ef zSome EALs is-are assessed based on the results of analyses that-ai'necessary to ascertain whether a specific EAL threshold has been exceeded-fe~g., osee.........., chem:ietry ca..pling, RCS* l....r.............

et........

The EAL and/or the associated basis discussion will identify the necessary analysis.

Il+4hese-ceoss

[ he 15-minute declaration period starts with the availability of the analysis results that show the 21 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 (a.g., maintain thec necezsary3 e-xpertie the EALs have been developed to address a full spectrum of possible events and conditions whieha-that 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 lipon judgment using EALs that-a-e-econsistent 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.#n22.2 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.

The evalation:e cCf a'n EAL(s) aluationt must be consistent with the related Operating Mode Applicability and Notes. If an EAL has been met or exceeded, t-he,-the IC is cnti.dere4-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 NSIRIDPR-ISG-01.CLASSIFICATION OF MULTIPLE EVENTS AND CONDITIONS Whaen-nth lcx cuct of multiple emezrgency z rent snrergcncics or conditions-are-present, the user will identify all l;AI s met or exceeded-E~.

The highest applicable ECL identified during this review is declared.

For example: If an Alert EAL and a Site Area Emergency EAL are met, -w.hether at cne unit .or at two' diffewnt a Site Area Emergency should be declared.There is no "additive" effect from multiple EALs meeting the sanme ECL. For example: If two Alert EALs are met, whether at ene unit or at tw.o dificrent unit, an Alert sheoi4-x ill be declared.Related guidance coner~ning-,irr 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.CONSIDERATION OF MODE CHANGES DURING CLASSIFICATION-The mode in effect at the time that-an event or condition occurred, and prior to 22 any plant or operator response, i.c the mode that dietermines whether or-met-an 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).-

Shu-tdow.'n mode orCLASSIFICATION OF IMMINENT CONDITIONS Although EALs provide specific thresholds, the emergency director must remain alert to events or conditions that could lead to meeting or exceeding an EAL within a relatively short period of time (i.e., a change in the ECL is IMMINENT).

If, in the judgrnent of the emergency director, meeting an EAL is IMMINE.NT, the emergency classification should w~ill be made as if-though 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.EMERGENCY CLASSIFICATION LEVEL UPGRADING AND DOWNGRADING SNCi policy is thati once a'n emergnc.\

".-hzreX~hcn an EAL is briefly met during an expected (normal) plant response, an emergency declaration is not warranted provided that associated systems and components are operating as expected, and operator actions are performed in accordance with procedures.

EAL momentarily met but the condition is corrected prior to an emergency declaration

-If an operator takes prompt manual action to address a condition, and the action is successful in correcting the condition prior to the emergency declaration, then the applicable EAL is not considered met and the associated emergency declaration is not requiredv.

....pl... i c, ampl.presents an illustration:

An ATWS occurs and the auxiliary feedwater system fails to automatically start.Steam generator levels rapidly decrease and the plant enters an inadequate RCS heat removal condition (a potential loss of both the fuel clad and RCS barriers).

If an operator manually starts the auxiliary feedwater system in accordance with an EOP step and clears the inadequate RCS heat removal condition prior to an emergency declaration, then the classification ill be based on the ATWS only.It is important to stress that the 15-minute emergency classification assessment period is not a "grace period" during which a classification may be delayed to allow the 24 performance of a corrective action that would obviate the need to classify the event;emergency classification assessments must be deliberate and timely, with no undue delays. The provision discussed above addresses only those rapidly evolving situations where an operator is able to take a successful corrective action prior to the emergency director completing the review and steps necessary to make the emergency declaration.

This provision is included to ensure that any public protective actions resulting from the emergency classification are truly warranted by the plant conditions.AFTER-THE-FACT DISCOVERY OF AN EMERGENCY EVENT OR CONDITION In some cases, an EAL may be met but the emergency classification was not made at the time of the event or condition.

This sd"-tizn c-'n a, cur -.hcn pl'ersonnel could discover#hmt-an event or condition existed ,hieh-i t,-hat met an EAL, but no emergency was declared, and the event or condition no longer exists at the time of discovery.

Specifically, the event shotald-will be reported to the NRC in accordance with 10 CFR § 50.72 within one hour of the discovery of the undeclared event or condition.

The licensee also notify appropriate state and local agencies in accordance with the agreed upon arrangements.

(1) Reading on ANY of the following radiation monitors greater than the reading shown for 15 minutes or longer: (2) Dose assessment using actual meteorology indicates doses greater than 1,000 mrem TEDE or 5,000 mrem thyroid CDE at or beyond (sitz spezifc dc~ rccptzr pc,:nt)thc et (3) Field survey results indicate EITHER of the following at or beyond {(~espte pcl.e-d4ese

  • Closed window dose rates greater than 1,000 mR/hr expected to continue for 60 minutes or longer.* Analyses of field survey samples indicate thyroid CDE greater than 5,000 mrem for one hour of inhalation.

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.Radiological effluent EALs are also-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions 27 NZ~4Moe~ o~

alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.

[he monitor reading threshold values are determined using a dose as~sessment method that back calculates horo the dose values s 1~ci l~ed inl thle IC. I he nmeteorolo)g and source term (noble gases. particulates, and halogens)used are the same as those used to determine the monitor reading threshold

,,altues in los RS 1 and RA1 IlIis protocol \ill maintain intervals btw.t\een the threshold valoes 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 11000 ml~hour ,a hole bod\ or 50)00 mR/hour thy roid. xxhichlever 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.Th eiu.. nt .... z!"EAI " are included te pro;vide a bacis f-r cla"ifyin:

As such, they represent an actual or potential substantial degradation of the level of plant safety of the plnt, lVhe spent hitel pool level itnstrutnent is located outside the control room but in close proximity.

This IC applies to irradiated fuel that is licensed for dry storage up to the point that the loaded storage cask is sealed. Once sealed, damage to a loaded cask causing loss of the CONFINEMENT BOUNDARY is classified in accordance with IC E-HU1.Escalation of the emergency we*4d-eis based on either Recognition Category R or C ICs.EAL # 1 39 This EAL escalates from RU2.

loss of level, in the affected portion of the REFUELING PATHWAY, is of sufficient magnitude to have resulted in uncovery of irradiated fuel. Indications of irradiated fuel uncovery may include direct or indirect visual observation (e.g., reports from personnel or camera images), es-we'l4-as-significant changes in water and radiation levels, or other plant parameters.

Computational aids may also be used (e.g., a boil-off curve). Classification of an event using this EAL should-will be based on the totality of available indications, reports and observations.

While an area radiation monitor could detect an increase in a dose rate due to a lowering of water level in some portion of the REFUELING PATHWAY, the reading may not be a reliable indication of whether or'--ie4-the fuel is actually uncovered.

To the degree possible, readings sheoi4d-wilI be considered in combination with other available indications of inventory loss.A drop in water level above irradiated fuel within the reactor vessel may be classified in accordance

This 1C addresses elevated radiation levels in certain plant rooms/areas sufficient to preclude or impede personnel from performing actions necessary to maintain normal plant operation, or to perform a normal plant cooldown and shutdown.

As such, it represents an actual or potential substantial degradation of the level of plant safety- of.he-plan+.

The emergency director should consider the cause of the increased radiation levels anid determine if another IC may be applicable.

For EAL #2, an Alert declaration is warranted if entry into the affected room/area is, or may be, procedurally required during the plant operating mode in effect at the time of the elevated radiation levels. The emergency classification is not contingent upon whether entry is actually necessary at the time of the increased radiation levels. Access sh**4-xill be considered as impeded if extraordinary measures are necessary to facilitate entry of personnel into the affected room/area (e.g., installing temporary shielding, requiring use of non-routine protective equipment, requesting an extension in dose limits beyond normal administrative limits).An emergency declaration is not warranted if any of the following conditions apply.* The plant is in an operating mode different than the mode specified for the affected room/area (i.e., entry is not required during the operating mode in effect at the time of the elevated radiation levels). For example, the plant is in Mode 1 when the radiation increase occurs, and the procedures used for normal operation, cooldown and shutdown do not require entry into the affected room until Mode 4.* The increased radiation levels are a result of a planned activity that includes compensatory measures which address the temporary inaccessibility of a room or area (e.g., radiography, spent filter or resin transfer, etc.).* The action for which room/area entry is required is of an administrative or record keeping nature (e.g., normal rounds or routine inspections).

[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 4-he-abve~elhis list is not all-inclusive.

wnd41t is strongly recommended that scheme developers consult with licensingLand regulatory compliance personnel to identify and understand all applicable requirements and guidance.

Questions say-also may 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 1 0 CFR § 50 and the guidance in NUREG 0654/FEMA-REP-I1.

The initiating conditions germane to a 10 CFR § 72.32 emergency plan (as described in NUREG-1 567) are e'ibs',med-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 ICsiEALs.

I-addieltrAdditionlaIlx, appropriate aspects of IC HUI and IC I-AlI shu4vill also be included to address a HOSTILE ACTION directed against an ISFSI.The analysis of potential onsite and offsite consequences of accidental releases associated with the operation of an ISFSI is contained in NUREG-l 1140, A Regulatory Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees.

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.

for The Fukushima Daiichi accident of March 11, 2-O42011 , 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, mtad ultimately led-Icadino to core damage in three reactors. -While-A ithouch the loss of power also impaired the spent fuel pool cooling function, sufficient water inventory was maintained in the pools to preelede-picx cnt fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that sevefa 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).

Amoang them to pfe4de)nc such meas~ure that each spent fuel pool be providcd with reliable level instrumentation to significantly enhance the ability of key decision-makers to ecl'cctix cily allocate resources effeetively-following a beyond design basis event. To this end, the NRC issued Order LA- 12-051!, Issuance of Order to Modif 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-12-051 states, in part, "All licensees

(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 make-up water addition should no longer be deferred." Toethi5 end, aAll licensees must t herc Iorc provide:* A primary and back-up level instrument that will monitor water level from the normal 2 level to the top of the used fuel rack in the pool..* A display in an area accessible following a severe event;-maid.

  • Independent electrical power to each instrument channel and p*e4ean alternate remote power connection capability.

NEI 12-02, Industry Guidance for Compliance with NRC Order EA-12-051, 'To Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation

", provides guidance for complying with NRC Order EA-12-051I.

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-12-05 1. 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).

In accerdance

with thi'&reguileae!4, !,icensees are responsible for evaluating a proposed change and determining whether or not it results in a reduction in the plan>'s effectiveness-ef the-pl=n.

Instrumentation used for EALo aced not be safety rclated, addressed by a Technical Specification or ODCMJRETS control reguiremont, no~ powered from an emergency power source; ho;;ever, EAL dc slopers should strive to incorporate instrumentation that is reliabic and routinely maintained in accordance with site programs and procedures.

Alanns refereneed in EAL statements should bo those that arc the most oporationally significant for the described event or condition.

Scheme developers should ensure that specifiod value 0 used as EAL setpoints are within the calibratad range of the referenced instrumentation, and consider any automatic inotrumentation functions that may impact acourata EAL assesoment.

In addition, EAL sctpoint values should not use tenno such as "off scale low" or "off scale high" since that type of reading may not bc readily differentiatcd from an instrument failure.

............

g-, ..Ior an'. 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). pkls-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 s-eIuld-w ill be based uipon valid indications, reports or conditions.

A valid indication, report, or condition, ne that-has been verified appropriate means. uhta ............

bIet in no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.

For example, validation could be thrc-gh an instrument channel check, response on related or redundant indicators, or direct observation by plant personnel.

h e4 !ndications be ..... p .... vahdldtcd in a manner that supports timely emergency declaration.

For ICs and EALs that have a stipulated time duration (e.g., 15 ......,.3.........,........

, the emergency director sh ld-.I not wait until the applicable time has elapsed, but shudwill 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 shu4will be assumed that the release duration specified in the IC/EAL has been exceeded, absent data to the contrary.A planned work activity #ht-vet....

....... s tlsrlting in an expected event or condition whieho-tlhal 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 t4iesesuelh cases, the controls associated with the planning, preparation and execution of the work will ensure *4hat-compliance wsith the opetating license is maintained, with all acpcctc of the pecrazting licence provided t-It-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.The asceccment ,ef zSome EALs is-are assessed based on the results of analyses that-ai'necessary to ascertain whether a specific EAL threshold has been exceeded-fe~g., osee.........., chem:ietry ca..pling, RCS* l....r.............

et........

The EAL and/or the associated basis discussion will identify the necessary analysis.

Il+4hese-ceoss

[ he 15-minute declaration period starts with the availability of the analysis results that show the 21 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 (a.g., maintain thec necezsary3 e-xpertie the EALs have been developed to address a full spectrum of possible events and conditions whieha-that 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 lipon judgment using EALs that-a-e-econsistent 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.#n22.2 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.

The evalation:e cCf a'n EAL(s) aluationt must be consistent with the related Operating Mode Applicability and Notes. If an EAL has been met or exceeded, t-he,-the IC is cnti.dere4-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 NSIRIDPR-ISG-01.CLASSIFICATION OF MULTIPLE EVENTS AND CONDITIONS Whaen-nth lcx cuct of multiple emezrgency z rent snrergcncics or conditions-are-present, the user will identify all l;AI s met or exceeded-E~.

The highest applicable ECL identified during this review is declared.

For example: If an Alert EAL and a Site Area Emergency EAL are met, -w.hether at cne unit .or at two' diffewnt a Site Area Emergency should be declared.There is no "additive" effect from multiple EALs meeting the sanme ECL. For example: If two Alert EALs are met, whether at ene unit or at tw.o dificrent unit, an Alert sheoi4-x ill be declared.Related guidance coner~ning-,irr 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.CONSIDERATION OF MODE CHANGES DURING CLASSIFICATION-The mode in effect at the time that-an event or condition occurred, and prior to 22 any plant or operator response, i.c the mode that dietermines whether or-met-an 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).-

Shu-tdow.'n mode orCLASSIFICATION OF IMMINENT CONDITIONS Although EALs provide specific thresholds, the emergency director must remain alert to events or conditions that could lead to meeting or exceeding an EAL within a relatively short period of time (i.e., a change in the ECL is IMMINENT).

If, in the judgrnent of the emergency director, meeting an EAL is IMMINE.NT, the emergency classification should w~ill be made as if-though 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.EMERGENCY CLASSIFICATION LEVEL UPGRADING AND DOWNGRADING SNCi policy is thati once a'n emergnc.\

The following guidance should be applied to the classification of these conditions.

EAL momentarily met during expected plant response -In in~tances

".-hzreX~hcn an EAL is briefly met during an expected (normal) plant response, an emergency declaration is not warranted provided that associated systems and components are operating as expected, and operator actions are performed in accordance with procedures.

EAL momentarily met but the condition is corrected prior to an emergency declaration

-If an operator takes prompt manual action to address a condition, and the action is successful in correcting the condition prior to the emergency declaration, then the applicable EAL is not considered met and the associated emergency declaration is not requiredv.

Fz ..

............

.hzu f..la..ng

....pl... i c, ampl.presents an illustration:

An ATWS occurs and the auxiliary feedwater system fails to automatically start.Steam generator levels rapidly decrease and the plant enters an inadequate RCS heat removal condition (a potential loss of both the fuel clad and RCS barriers).

If an operator manually starts the auxiliary feedwater system in accordance with an EOP step and clears the inadequate RCS heat removal condition prior to an emergency declaration, then the classification ill be based on the ATWS only.It is important to stress that the 15-minute emergency classification assessment period is not a "grace period" during which a classification may be delayed to allow the 24 performance of a corrective action that would obviate the need to classify the event;emergency classification assessments must be deliberate and timely, with no undue delays. The provision discussed above addresses only those rapidly evolving situations where an operator is able to take a successful corrective action prior to the emergency director completing the review and steps necessary to make the emergency declaration.

This provision is included to ensure that any public protective actions resulting from the emergency classification are truly warranted by the plant conditions.AFTER-THE-FACT DISCOVERY OF AN EMERGENCY EVENT OR CONDITION In some cases, an EAL may be met but the emergency classification was not made at the time of the event or condition.

This sd"-tizn c-'n a, cur -.hcn pl'ersonnel could discover#hmt-an event or condition existed ,hieh-i t,-hat met an EAL, but no emergency was declared, and the event or condition no longer exists at the time of discovery.

Specifically, the event shotald-will be reported to the NRC in accordance with 10 CFR § 50.72 within one hour of the discovery of the undeclared event or condition.

The licensee also notify appropriate state and local agencies in accordance with the agreed upon arrangements.

Basis: This IC addresses a release of gaseous or liquid radioactivity that results in projected or actual offsite doses greater than or equal to l-%-perccnt of the EPA Protective Action Guides (PAGs).It includes both monitored and un-monitored releases.

Releases of this magnitude represent an actual or potential substantial degradation of the level of plani safety efthe-plaw, as indicated by 35 a radiological release that significantly exceeds regulatory limits (e.g., a significant uncontrolled release).Radiological effluent EALs are e4se-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.

The monitor reading thareshold values arc determined using a dose assesslment method that back calculates from the dose values specified in the IC. The meteorology and source term (noble gases. particulates.

and halogens)used is the same as those used to determine the monitor reading threshold values in IC's R Il and RS I. [his protocol maintains intervals bet~xcen the threshold values for the three classifications.

Since doses are gencrallx not monitored in real-time, a release duration of one hour is assumed.and the threshold values arc based on a site boundary (or beyond) dose of It) mR/hour wvhole body or 50 mR/hour thxroid, whichever is more limiting.The TEDE dose is set at 1%- percent of the EPA PAG of 1,000 mrem while the 50 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.Escalation of the emergency classification level we,:'-udbe-viauses IC RS 1.af fission product barriers, challenged, but rathe~r the amount af radioactivity released ta the and- the commited effecti;ve dase equivalent CEDE), er as the thyraid e.u.aen rCDE)^.

As such, they represent an actual or potential substantial degradation of the level of plant safety of the plnt, lVhe spent hitel pool level itnstrutnent is located outside the control room but in close proximity.

This IC applies to irradiated fuel that is licensed for dry storage up to the point that the loaded storage cask is sealed. Once sealed, damage to a loaded cask causing loss of the CONFINEMENT BOUNDARY is classified in accordance with IC E-HU1.Escalation of the emergency we*4d-eis based on either Recognition Category R or C ICs.EAL # 1 39 This EAL escalates from RU2.

loss of level, in the affected portion of the REFUELING PATHWAY, is of sufficient magnitude to have resulted in uncovery of irradiated fuel. Indications of irradiated fuel uncovery may include direct or indirect visual observation (e.g., reports from personnel or camera images), es-we'l4-as-significant changes in water and radiation levels, or other plant parameters.

Computational aids may also be used (e.g., a boil-off curve). Classification of an event using this EAL should-will be based on the totality of available indications, reports and observations.

While an area radiation monitor could detect an increase in a dose rate due to a lowering of water level in some portion of the REFUELING PATHWAY, the reading may not be a reliable indication of whether or'--ie4-the fuel is actually uncovered.

To the degree possible, readings sheoi4d-wilI be considered in combination with other available indications of inventory loss.A drop in water level above irradiated fuel within the reactor vessel may be classified in accordance

This 1C addresses elevated radiation levels in certain plant rooms/areas sufficient to preclude or impede personnel from performing actions necessary to maintain normal plant operation, or to perform a normal plant cooldown and shutdown.

As such, it represents an actual or potential substantial degradation of the level of plant safety- of.he-plan+.

The emergency director should consider the cause of the increased radiation levels anid determine if another IC may be applicable.

For EAL #2, an Alert declaration is warranted if entry into the affected room/area is, or may be, procedurally required during the plant operating mode in effect at the time of the elevated radiation levels. The emergency classification is not contingent upon whether entry is actually necessary at the time of the increased radiation levels. Access sh**4-xill be considered as impeded if extraordinary measures are necessary to facilitate entry of personnel into the affected room/area (e.g., installing temporary shielding, requiring use of non-routine protective equipment, requesting an extension in dose limits beyond normal administrative limits).An emergency declaration is not warranted if any of the following conditions apply.* The plant is in an operating mode different than the mode specified for the affected room/area (i.e., entry is not required during the operating mode in effect at the time of the elevated radiation levels). For example, the plant is in Mode 1 when the radiation increase occurs, and the procedures used for normal operation, cooldown and shutdown do not require entry into the affected room until Mode 4.* The increased radiation levels are a result of a planned activity that includes compensatory measures which address the temporary inaccessibility of a room or area (e.g., radiography, spent filter or resin transfer, etc.).* The action for which room/area entry is required is of an administrative or record keeping nature (e.g., normal rounds or routine inspections).

  • The access control measures are of a conservative or precautionary nature, and would not actually prevent or impede a required action.Escalation of the emergency classification level w6*ouj44be-'4ause., Recognition Category R, C or F ICs.De2ATe N1 E..
