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-re4'iew-eoft Ihe relevant sections libtcd belzwv will aid thc reader in:..-raanding e ter., inalagy ...... avd in Sctin. 3.0 offor this document, arc:* 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 Organization Theab 1e hose regulations are supplemented by guidance documents.

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

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 Reactorsl his list is not all-inclusive. is strongly recommended that scheme developers consult with licensing!

and regulatory compliance personnel to identify and understand all applicable requirements and guidance.

Questions ffay-also niay 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 aubumed-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.

IC E-HU 1 covers natural and man-made events included within the scope of an ISFSI design. This IC is not applicable to installations or facilities that may process and/or repackage spent fuel. a Manitar.ad R oric... l, Scr .... Faciit ...an 1SFS! at. a pent fu:el precezi:ng facility).

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

dditonally, appropriate aspects of IC HU!I and IC HAl should 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-1 140, 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 1 rem Effective Dose Equivalent.

-;ith thece for r..uire fcra 10. CFR § 72.32 ..m.rg.n.. plan ic diffcernt than that prescribed fcr a 10 1.3 NRC ORDER EA-12-051 The Fukushima Daiichi accident of March 11, II, 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, mafd ultimately led-Jeading to core damage in three reactors.

W¥hile-Although the loss of power also impaired the spent fuel poo1 cooling function, sufficient water inventory was maintained in the pools to tf-e1d~e-prevent fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that several 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).

Amon g them t,'ore pro,,4de )ne such measure wvas that each spent fuel pool be prov idcd with reliable level instrumentation to significantly enhance the ability of key decision-makers to efkt~ci',cly allocate resources effect~'ely-following a beyond design basis event. To this end, the NRC issued Order EA- 12-051, Issuance of Order to Modi~fy Licenses with Regard to Reliable Spent Fuel Pool Instrumentation, on March 12, 2012, to all U.S. 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 poo1 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." To this-erd-e AII licensees must therefobre 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; and* Independent electrical power to each instrument channel and pfe.vide-an 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-12-05 1.NEI 99-01, Revision 6, includes three EALs that reflect the availability of the enhanced spent fuel pooi 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 acczrdance wi'th thi5 regu.l-t~cefi, Licensees are responsible for evaluating a proposed change and determining whether or not it results in a reduction in the effectiveness of the plan. a, result cfthe lie 1eesascd on this determination, the licensee will either make the change or submit it to the NRC for prior review and approval in accordance with 10 CFR 50.90.3

.-q.42. I GENERAL CONSIDERATIONS

..........

...fig-e.tl-r 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),

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 NRCs~'.. guidance on implementing this requirement in NSIR/DPR-ISG-01, Interim Staff Guidance, Emergency Planning for Nuclear Power Plants.All emergency classification assessments sheoI4-xx iii be based upon valid indications, reports or conditions.

A valid indication, report, or condition, i -eue-+hut-has been verified thfeah-u~sing appropriate means..........t........

lca'. ing no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.

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

4-e~.°;alidnti af zhe'ul'd e ..... h..... ndicat t n xxiil be vatlid~ated in a manner that supports timely emergency declaration.

For ICs and EALs that have a stipulated time duration (e.g.,, IS m'nutez .... 30" minte,,-.:...

etc.), the emergency director shetild-x~

iii not wait until the applicable time has elapsed, but sheutld-vill 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 shudwili be assumed that the release duration specified in the ICiEAL has been exceeded, absent data to the contrary.A planned work.activity..e suihrcumin in an expected event or condition w#hieh-that 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 theseo-such cases, the controls associated with the planning, preparation and execution of the work will ensure t#ht-compliance xx ith the operat in ' license iz

with all of the~v ....ratin'"g litence provided that 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 asze~zment o~f cSome EALs is-are axsessed based on the results of analyses #-ha4-ere necessary to ascertain whether a specific EAL threshold has been exceeded-(e~g.,-d~es

..........., cheiz. ...p.... , RCS leak rate .......t.. n,: et.)...' The EAL and/or the associated basis discussion will identify the necessary analysis.

In these -e.ees.e4 tlhe 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 (e.g., maintain the .. ..

the EALs have been developed to address a full spectrum of possible events and conditions wh-ieb4-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 upon judgment using EALs with the emergency classification level (ECL) definitions (refer to Category H). The emergency director will 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.

The c;'al",atizn c~f pAn EAL(s) evaluation must be consistent with the related operating mode applicability and notes. If an EAL has been met or exceeded,*lhim-the IC is eensidefedre-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 WhnIn the cv clt of multiple effergency emergencies conditions-are-prceent, 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, ;whether at, one u-niter ...I. .,..awe .if ..r.n a Site Area Emergency should be declared.There is no "additive" effect from multiple EALs meeting the same ECL. For example: If two Alert EALs are met, at ..... uni ... at .... difren unit.. , an Alert sho,,ld-xx ill be declared.Related guidance eeneeffiifg-fbr 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 DURlING CLASSIFICATION oThe mode in effect at the time thot-an event or condition occurred, and prior to 22 any plant or operator response, ic the merde that determines whether 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).

(o .... hihe d)iseteeCLASSIFICATION 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 judgment of the emergency director, meeting an EAL is IMMINENT, the emergency classification eh*4be made as 4.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 SNC policy is that once anl emergency classification is made, it cannot be downgraded to a lower classification.

Tecrmination criteria contained in procedure A,./iP-tIP-I 1(1, Emergency ( ka~slyica, ion nod InitialAc/ions shall be completed for' an event to be terminated.

At termination, on an event specific basis, the site will enter either normal operating conditions or a recoscr'.

-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 required.

[his example 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 shetld-will be based on the ATWS only.It is important to stf-ess-note that the 15-minute emergency classification assessment period is not a "grace period" dclax a classification .eGei order to eperforma,,ee-ef a corrective action that would obviate the need to 24 classify the event,-.

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 alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses 27 Re the spectrum of possible accident events and conditions.

I he monitor reading threshold are determined usini a dose assessment method that back calculates the (lose values specitied in the It. [he mecteologom, and source term (noble gases, particulates.

and halogens)used are the same as those used to> determine the monitor reading threshold values in I's RS I and RAI. this protocol will maintain intervals bctvceent the threshold values tbr thle three classificationms.

Basis: This IC addresses a release of gaseous radioactivity that results in projected or actual offsite doses greater than or equal to 10%- percent of the EPA Protective Action Guides (PAGs). It includes both monitored and un-monitored releases.

Releases of this magnitude are associated with the failure of plant systems needed for the protection of the public.Radiological effluent EALs are alse-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions 31 I~1aW05 alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.

T[he monitor reading threshold values arc determined using a dose aLssessment method that hack calculates fi'om the dose xalues specilied in the IC. The meteorology, and source term (noble gases. pal iculates, and halogens~)

used is the same as those used to determine the monitor reading thresltold xalues in ICs R Il and RAI. this protocol maintains intervals hetween the threshold values for the three classilications, Since doses arc generallN not monitored in real-time, a releakse duration of one hour is assumed.and the threshtold xalnes are based on a site boundary (or beyond} dose of I0 rotlLRhour whole body or 5010 ntR/hour thy'roid.

As such, they represent an actual or potential substantial degradation of the level ofs~afety' of he-plantplant satietx.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-HUI.Escalation of the emergency woe, i4.beis based on either Recognition Category R or C ICs.EAL #1 This EAL escalates from RU2. is-4hbt-t

[he 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), as-weIJ-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 sheutd-xt, ill be based on the totality of available indications, reports and observations.

39 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 e*--net-the fuel is actually uncovered.

To the degree possible, readings sheld-ill 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 vx, ith Recognition Category C during the Cold Shutdown and Refueling modes.EAL #2_This EAL addresses a release of radioactive material caused by mechanical damage to irradiated fuel. Damaging events may include the dropping, bumping or binding of an assembly, or dropping a heavy load onto an assembly.

A rise in readings on radiation monitors be considered in conjunction with in-plant reports or observations of a potential fuel damaging event (e.g., a fuel handling accident).

Containment Purge Ventilation Monitors are not available during all modes.EAL #3 Spent fuel pool water level at this value is within the lower end of the level range necessary to prevent significant dose consequences from direct gamma radiation to personnel performing operations in the vicinity of the spent fuel pool. [he spoint fuel pool level instrument is located outside the (iontrol Roomi but in close proximnity.

The emergency classification is not contingent upon whether entry is actually necessary at the time of the increased radiation levels. Access shi ,-~ill 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 whieh-to 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).

Further, t.here are e,\dministrative controls are established to prevent unintentional releases, and to control and monitor intentional releases.

The occurrence of an extended, uncontrolled radioactive release to the environment is-iiadiea'ive-e*idicates degradation in these features and/or controls.Radiological effluent EALs are aIso-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.

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.Releases sheuld-will not be prorated or averaged.

For example, a release exceeding 4 times release limits for 30 minutes does not meet the EAL.EAL # 1 -This EAL addresses normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways.EAL #2 -This EAL addresses radioactivity releases that cause effluent radiation monitor readings to exceed 2 times the limit established by a radioactivity discharge permit.

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-re4'iew-eoft Ihe relevant sections libtcd belzwv will aid thc reader in:..-raanding e ter., inalagy ...... avd in Sctin. 3.0 offor this document, arc:* 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 Organization Theab 1e hose regulations are supplemented by guidance documents.

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

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 Reactorsl his list is not all-inclusive. is strongly recommended that scheme developers consult with licensing!

and regulatory compliance personnel to identify and understand all applicable requirements and guidance.

Questions ffay-also niay 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 aubumed-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.

IC E-HU 1 covers natural and man-made events included within the scope of an ISFSI design. This IC is not applicable to installations or facilities that may process and/or repackage spent fuel. a Manitar.ad R oric... l, Scr .... Faciit ...an 1SFS! at. a pent fu:el precezi:ng facility).

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

dditonally, appropriate aspects of IC HU!I and IC HAl should 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-1 140, 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 1 rem Effective Dose Equivalent.

-;ith thece for r..uire fcra 10. CFR § 72.32 ..m.rg.n.. plan ic diffcernt than that prescribed fcr a 10 1.3 NRC ORDER EA-12-051 The Fukushima Daiichi accident of March 11, II, 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, mafd ultimately led-Jeading to core damage in three reactors.

W¥hile-Although the loss of power also impaired the spent fuel poo1 cooling function, sufficient water inventory was maintained in the pools to tf-e1d~e-prevent fuel damage from the loss of cooling.Following a review of the Fukushima Daiichi accident, the NRC concluded that several 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).

Amon g them t,'ore pro,,4de )ne such measure wvas that each spent fuel pool be prov idcd with reliable level instrumentation to significantly enhance the ability of key decision-makers to efkt~ci',cly allocate resources effect~'ely-following a beyond design basis event. To this end, the NRC issued Order EA- 12-051, Issuance of Order to Modi~fy Licenses with Regard to Reliable Spent Fuel Pool Instrumentation, on March 12, 2012, to all U.S. 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 poo1 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." To this-erd-e AII licensees must therefobre 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; and* Independent electrical power to each instrument channel and pfe.vide-an 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-12-05 1.NEI 99-01, Revision 6, includes three EALs that reflect the availability of the enhanced spent fuel pooi 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 acczrdance wi'th thi5 regu.l-t~cefi, Licensees are responsible for evaluating a proposed change and determining whether or not it results in a reduction in the effectiveness of the plan. a, result cfthe lie 1eesascd on this determination, the licensee will either make the change or submit it to the NRC for prior review and approval in accordance with 10 CFR 50.90.3

.-q.42. I GENERAL CONSIDERATIONS

..........

...fig-e.tl-r 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),

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 NRCs~'.. guidance on implementing this requirement in NSIR/DPR-ISG-01, Interim Staff Guidance, Emergency Planning for Nuclear Power Plants.All emergency classification assessments sheoI4-xx iii be based upon valid indications, reports or conditions.

A valid indication, report, or condition, i -eue-+hut-has been verified thfeah-u~sing appropriate means..........t........

lca'. ing no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.

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

4-e~.°;alidnti af zhe'ul'd e ..... h..... ndicat t n xxiil be vatlid~ated in a manner that supports timely emergency declaration.

For ICs and EALs that have a stipulated time duration (e.g.,, IS m'nutez .... 30" minte,,-.:...

etc.), the emergency director shetild-x~

iii not wait until the applicable time has elapsed, but sheutld-vill 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 shudwili be assumed that the release duration specified in the ICiEAL has been exceeded, absent data to the contrary.A planned work.activity..e suihrcumin in an expected event or condition w#hieh-that 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 theseo-such cases, the controls associated with the planning, preparation and execution of the work will ensure t#ht-compliance xx ith the operat in ' license iz

with all of the~v ....ratin'"g litence provided that 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 asze~zment o~f cSome EALs is-are axsessed based on the results of analyses #-ha4-ere necessary to ascertain whether a specific EAL threshold has been exceeded-(e~g.,-d~es

..........., cheiz. ...p.... , RCS leak rate .......t.. n,: et.)...' The EAL and/or the associated basis discussion will identify the necessary analysis.

In these -e.ees.e4 tlhe 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 (e.g., maintain the .. ..

the EALs have been developed to address a full spectrum of possible events and conditions wh-ieb4-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 upon judgment using EALs with the emergency classification level (ECL) definitions (refer to Category H). The emergency director will 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.

The c;'al",atizn c~f pAn EAL(s) evaluation must be consistent with the related operating mode applicability and notes. If an EAL has been met or exceeded,*lhim-the IC is eensidefedre-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 WhnIn the cv clt of multiple effergency emergencies conditions-are-prceent, 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, ;whether at, one u-niter ...I. .,..awe .if ..r.n a Site Area Emergency should be declared.There is no "additive" effect from multiple EALs meeting the same ECL. For example: If two Alert EALs are met, at ..... uni ... at .... difren unit.. , an Alert sho,,ld-xx ill be declared.Related guidance eeneeffiifg-fbr 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 DURlING CLASSIFICATION oThe mode in effect at the time thot-an event or condition occurred, and prior to 22 any plant or operator response, ic the merde that determines whether 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).

(o .... hihe d)iseteeCLASSIFICATION 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 judgment of the emergency director, meeting an EAL is IMMINENT, the emergency classification eh*4be made as 4.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 SNC policy is that once anl emergency classification is made, it cannot be downgraded to a lower classification.

Tecrmination criteria contained in procedure A,./iP-tIP-I 1(1, Emergency ( ka~slyica, ion nod InitialAc/ions shall be completed for' an event to be terminated.

At termination, on an event specific basis, the site will enter either normal operating conditions or a recoscr'.

-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 required.

[his example 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 shetld-will be based on the ATWS only.It is important to stf-ess-note that the 15-minute emergency classification assessment period is not a "grace period" dclax a classification .eGei order to eperforma,,ee-ef a corrective action that would obviate the need to 24 classify the event,-.

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 alone.

Basis: This IC addresses a release of gaseous radioactivity that results in projected or actual offsite doses greater than or equal to 10%- percent of the EPA Protective Action Guides (PAGs). It includes both monitored and un-monitored releases.

Releases of this magnitude are associated with the failure of plant systems needed for the protection of the public.Radiological effluent EALs are alse-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions 31 I~1aW05 alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.

T[he monitor reading threshold values arc determined using a dose aLssessment method that hack calculates fi'om the dose xalues specilied in the IC. The meteorology, and source term (noble gases. pal iculates, and halogens~)

Basis: This IC addresses a release of gaseous or liquid radioactivity that results in projected or actual offsite doses greater than or equal to 1-%- percent 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 sefety -ef the satbty, as 35 ii indicated by a radiological release that significantly exceeds regulatory limits (e.g., a significant uncontrolled release).Radiological effluent EALs are al4ie-included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions alone.

As such, they represent an actual or potential substantial degradation of the level ofs~afety' of he-plantplant satietx.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-HUI.Escalation of the emergency woe, i4.beis based on either Recognition Category R or C ICs.EAL #1 This EAL escalates from RU2. is-4hbt-t

[he 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), as-weIJ-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 sheutd-xt, ill be based on the totality of available indications, reports and observations.

39 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 e*--net-the fuel is actually uncovered.

To the degree possible, readings sheld-ill 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 vx, ith Recognition Category C during the Cold Shutdown and Refueling modes.EAL #2_This EAL addresses a release of radioactive material caused by mechanical damage to irradiated fuel. Damaging events may include the dropping, bumping or binding of an assembly, or dropping a heavy load onto an assembly.

A rise in readings on radiation monitors be considered in conjunction with in-plant reports or observations of a potential fuel damaging event (e.g., a fuel handling accident).

Containment Purge Ventilation Monitors are not available during all modes.EAL #3 Spent fuel pool water level at this value is within the lower end of the level range necessary to prevent significant dose consequences from direct gamma radiation to personnel performing operations in the vicinity of the spent fuel pool. [he spoint fuel pool level instrument is located outside the (iontrol Roomi but in close proximnity.

The emergency classification is not contingent upon whether entry is actually necessary at the time of the increased radiation levels. Access shi ,-~ill 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 whieh-to 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).

Further, t.here are e,\dministrative controls are established to prevent unintentional releases, and to control and monitor intentional releases.

The occurrence of an extended, uncontrolled radioactive release to the environment is-iiadiea'ive-e*idicates degradation in these features and/or controls.Radiological effluent EALs are aIso-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.

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.Releases sheuld-will not be prorated or averaged.

For example, a release exceeding 4 times release limits for 30 minutes does not meet the EAL.EAL # 1 -This EAL addresses normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways.EAL #2 -This EAL addresses radioactivity releases that cause effluent radiation monitor readings to exceed 2 times the limit established by a radioactivity discharge permit.
