Peach Bottom Atomic Power Station Annex Exelon Exelon Nuclear Nuclear Peach Bottom Atomic Power Station Annex Section 1: Introduction As required in the conditions set forth by the Nuclear Regulatory Commission (NRC) for the operating licenses for the Exelon Nuclear Stations, the management of Exelon recognizes its responsibility and authority to operate and maintain the nuclear power stations in such a manner as to provide for the safety of the general public.

The Exelon Emergency Preparedness Program consists of the Exelon Nuclear Standardized Radiological Emergency Plan, Station Annexes, emergency plan implementing procedures, and associated program administrative documents. The Exelon Nuclear Standardized Radiological Emergency Plan outlines the basis for response actions that would be implemented in an emergency. Planning efforts common to all Exelon Nuclear stations are encompassed within the Emergency Plan.

This document serves as the Peach Bottom Atomic Power Station Annex and contains information and guidance that is unique to the station. This includes Emergency Action Levels (EALs), and facility geography and location for a full understanding and representation of the station's emergency response capabilities. The Station Annex is subject to the same review and audit requirements as the Exelon Nuclear Standardized Radiological Emergency Plan per EP-AA-120, "Emergency Plan Administration".

1.1 Facility Description The Peach Bottom Atomic Power Station (PBAPS) is a fixed nuclear facility operated by Exelon Nuclear. The station consists of one High Temperature Gas Cooled Reactor designated as Unit 1, which is in the SAFSTOR status of decommissioning, two operating Boiling Water Reactors designated as Units 2 and 3, and an Independent Spent Fuel Storage Installation (ISFSI).

The PBAPS station is located partly in York County and partly in Lancaster County in southeastern Pennsylvania, on the west shore of Conowingo Pond, near the mouth of Rock Run Creek. The plant is about 38 miles NNE of Baltimore, MD; 65 miles WSW of Philadelphia, PA; 45 miles SE of Harrisburg, PA; and 20 miles SSE of Lancaster, PA.

Conowingo Pond is a reservoir formed by the backwater of Conowingo Dam on the Susquehanna River; the dam is located about 9 miles downstream from PBAPS. The nearest communities are Delta, PA, and Cardiff, MD, located approximately 4 and 6 miles WSW of the site, respectively.

For more specific site location information, refer to the Updated Final Safety Analysis Report (UFSAR) for Peach Bottom Atomic Power Station.

1.2 Emergency Planning Zones The Plume Exposure Emergency Planning Zone (EPZ) for Peach Bottom Atomic Power Station shall be an area surrounding the Station with a radius of about ten miles. The exact physical boundaries are determined by the Commonwealth of Pennsylvania, State of Maryland, and affected Counties). Refer to Figure PBAPS 1-1.

May 2003 PBAPS 1-1 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex Exelon Nuclear Peach Bottom Atomic Power Station Annex Exelon Nuclear The Ingestion Pathway Emergency Planning Zone (EPZ) for Peach Bottom Atomic Power Station shall be an area surrounding the Station with a radius of about 50 miles. Refer to Figure PBAPS 1-2.

1.3 Participating Governmental Agencies The overall responsibility for the management of the effects of accidental off-site releases of radioactivity resulting from either a nuclear power plant or a transportation accident rests with state and local governments.

The Commonwealth of Pennsylvania organizations having prime responsibility in matters of radiation hazards are the Pennsylvania Emergency Management Agency (PEMA) and the Bureau of Radiation Protection (BRP) of the Pennsylvania Department of Environmental Protection. State of Maryland organizations having primary responsibility in matters of radiation hazards are the Maryland Emergency Management Agency (MEMA) and the Technical Support Program of the Maryland Department of the Environment (MDE).

County and local governments are responsible for the protection of public health and safety within theirjurisdiction. Similarly, organizations in the Commonwealth of Pennsylvania and States of Maryland, Delaware, and New Jersey are responsible for the protection of the public in their states. Cooperation with the States of Delaware and New Jersey is necessary because these states are within the Ingestion Pathway EPZ.

These civil agencies will respond to provide support in the event of an emergency in the areas indicated below.

1.3.1 Pennsylvania Emergencv Management Agencv (PEMA)

Responsibilities of PEMA are outlined in Annex E, "Radiological Emergency Response to Nuclear Power Plant Incidents" of the Commonwealth of Pennsylvania Emergency Operations Plan.

1.3.2 Department of Environmental Protection. Bureau of Radiation Protection (DEP/BRP)

Responsibilities of DEP/BRP are outlined in Annex E of the Commonwealth of Pennsylvania Emergency Operations Plan.

1.3.3 Pennsalvania State Police Responsibilities of the State Police are set forth in Annex E of the Commonwealth of Pennsylvania Emergency Operations Plan.

Once an emergency is declared, the Emergency Response Organization (ERO) is activated as described in Section B.4 of the Exelon Nuclear Standardized Radiological Emergency Plan.

2.1 Shift Organization Staffing Required on-shift staffing in support of emergency response activities is 16 people. This on-shift staffing level exceeds the Exelon Nuclear Standardized Radiological Emergency Plan commitment often (10) people, based on existing commitments supporting the elimination of 30-minute augmentation goal from Table B-I of NUREG-0654/FEMA-REP-1.

A listing of minimum shift complement is provided in Table PBAPS 2-1 of the Annex for Peach Bottom Atomic Power Station (PBAPS). Based on existing on-shift staffing commitments, the "Minimum Shift Size" for the purposes of NUREG-0654, Table B-i comparison is 16 persons versus the 10 persons specified in the Exelon Nuclear Standardized Radiological Emergency Plan. These six (6) additional on-shift positions include:

  • 2nd Emergency Communicator
  • Two Field Survey Team Members
  • One Radwaste Operator (Equipment Operator)
  • One Instrument and Controls Technician
  • 3 rd Radiation Protection Technician (two at affected station and 3 rd at unaffected station performing dose assessor function).

2.1.1 Shift Dose Assessment The on-shift dose assessment function will be performed by a shift Radiation Protection Technician (RPT) at Limerick Generating Station. However, Peach Bottom Atomic Power Station will maintain the capability to perform a shift dose assessment, if necessary.

2.1.2 Shift Emergencv Communicators The Shift Communicator performs notifications to the State and County organizations until relieved by the TSC, and assists in the initiation of the ERO Callout System as directed. The Communicator position is staffed by a designated on-shift individual capable of responding to the Control Room immediately in support of the initiation of offsite notifications within 15 minutes of event classification.

A 2nd on-shift individual will be designated to support communications with the NRC over the Emergency Notification System (ENS) until relieved by the TSC.

Activation of the automated ERO call out system will be performed by the Shift Manager, but may be delegated to a Control Room Emergency Communicator or available on-shift staff.

I of the Exelon Nuclear Standardized Radiological Emergency Plan outlines the On-Shift Emergency Response Organization Assignment of the STA.

Peach Bottom Atomic Power Station has deemed the following as an acceptable method of implementing Section B. I in reference to the STA.

The responsibilities of the STA are delineated on OP-AA-101-1I 1, "Roles and Responsibilities of On-Shift Personnel." If the STA is the Shift Manager or Unit Supervisor, then another Senior Reactor Operator (SRO) shall assist as Incident Assessor during unexpected conditions and transients. Per Table B-1, the on-shift STA or Incident Assessor shall also provide core/thermal hydraulics support to Control Room staff.

2.2 Emergency Response Organization (ERO) Staffing Refer to Table PBAPS 2-1 of the PBAPS Annex, "Minimum Staffing Requirements", for a comparison against the Exelon Nuclear Standardized Radiological Emergency Plan of 60-minute and full augmentation commitments.

2.2.1 Emergency Onsite Organization (Figure PBAPS 2-2)

No changes in augmentation positions or staffing levels for the Technical Support Center (TSC), Operations Support Center (OSC) and Control Room from that specified in the Exelon Nuclear Standardized Radiological Emergency Plan.

2.2.2 Emergencv Offsite Organization (Figure PBAPS 2-3)

Based on existing interface and staffing agreements, representatives from the Commonwealth of Pennsylvania and State of Maryland will respond to the Emergency Operations Facility (EOF), allowing direct face-to-face communications. As such, the State Environs Communicator position, listed under the Exelon Nuclear Standardized Radiological Emergency Plan, is not staffed at the Coatesville EOF. Rather the EOF Environmental Coordinator will interface directly with State representatives present in the EOF.

An EOF Access Controller has been added to the Full Augmentation complement to support existing facility access control measures.

2.2.3 Emergency Public Information Organization (Figure PBAPS 2-4)

Based on the co-location of the EOF with the Joint Public Information Center (JPIC) the following Emergency News Center (ENC) functions, as described in Sections B.5.c and B.7 of the Exelon Nuclear Standardized Radiological Emergency Plan, have been eliminated or consolidated with corresponding JPIC positions. These differences in staffing are:

  • Public Information Liaison was deleted.
  • Radiation Protection Spokesperson was incorporated into the Radiological Advisor position
  • Technical Spokesperson was incorporated into the Technical Advisor position May 2003 PBAPS 2-2 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex Exelon Nuclear 2.3 Emergency Response Organization (ERO) Training Training is conducted in accordance with Section 0.5 of the Exelon Nuclear Standardized Radiological Emergency Plan per TQ-AA-1 13, "ERO Training and Qualification."

Retraining is performed on an annual basis, which is defined as every 12 months + 3 months (25% grace period).

2.4 Non-Exelon Nuclear Support Groups Agreements exist on file with or are verified current annually by the MAROG Corporate Emergency Preparedness Group for the following support agencies:

.0 Pennsylvania State Police

  • Cecil County, Emergency Management and Civil Defense Agency
  • Chester County Department of Emergency Service
  • Harford County Division of Emergency Operations
  • Memo of Understanding with Maryland Emergency Management Agency, Harford County Division of Emergency Operations, and Cecil County Emergency Management and Civil Defense Agency
  • Delta-Cardiff Volunteer Fire/Ambulance Company
  • Harford Memorial Hospital
  • Sadowsky Surgical Associates, PA
  • York Hospital Additionally, Exelon Nuclear has contractual agreements with several companies whose services would be available in the event of a radiological emergency. These agencies are listed in Appendix 3 of the Standard Plan. Emergency response coordination with governmental agencies and other support organizations is discussed in Section A of the Standard Plan.

2.5 Nuclear Steam Systems Supplier (NSSS)

General Electric Company maintains an Emergency Response Organization, which can provide technical assistance from their home office or at the site.

2.6 Architect/Engineer Bechtel or other contractors may be involved in the technical analysis or construction activities associated with the emergency response or recovery operation. Each such organization will designate a lead representative who will have the same responsibilities, within their scope of work, as described for the NSSS Contractor.

Section 3: Classification of Emergencies Section D of the Exelon Nuclear Standardized Radiological Emergency Plan describes five (5)

Emergency Classes. The first four are the Unusual Event, Alert, Site Area Emergency and General Emergency, and are listed from least severe to most severe according to relative threat to the health and safety of the public and emergency workers. The fifth level is Recovery and is considered as a phase of the emergency. Recovery is not considered as part of the event classification logic contained in Section 3.0 of the Annex, but rather is entered by meeting criteria provided in Section M of the Exelon Nuclear Standardized Radiological Emergency Plan.

Site specific definitions are provided for terms to be used for that particular Initiating Conditions tThreshold Values and may not be applicable to other uses of that term in any other EAL, at other sites, in the Exelon Nuclear Standardized Radiological Emergency Plan or procedures. Also included are the technical bases, which were used to develop the EAL.

Classifications are based on evaluation of each Unit. All classifications are to be based upon VALID indications, reports or conditions. Indications, reports or conditions are considered VALID when they are verified by (1) an instrument channel check, or (2) indications on related or redundant indicators, or (3) by direct observation by plant personnel, such that doubt related to the indicator's operability, the condition's existence, or the report's accuracy is removed. Implicit in this definition is the need for timely assessment.

When two or more Emergency Action Levels are determined, declaration will be made on the highest classification level for the Unit. When both units are affected, the highest classification for the Station will be used for notification purposes and both units' classification levels will be noted.

3.1 Emergency Action Levels (EALs)

Emergency Action Levels are the measurable, observable detailed conditions that must be met in order to classify the event. Classification shall not be made without referencing, comparing and satisfying the threshold values specified in the Emergency Action Levels. Mode Applicability provides the unit conditions when the Emergency Action Levels represent a threat. The Basis provides definitions of terms, explanations and justification for including the Initiating Condition and Emergency Action Level. Definitions are provided for terms having specific meaning as they relate to this procedure.

Unusual Event, Alert, Site Area Emergency, and General Emergency classifications are entered by meeting designated Emergency Action Levels (EALs) Threshold Values. These values are based on the criteria established under Revision 2 to NUMARCINESP-007, "Methodology for Development of Emergency Action Levels" (dated January 1992), and are labeled based on the four Recognition Categories outlined in NUMARCINESP-007:

  • Abnormal Radiological Levels / Effluents
  • Fission Product Barrier Degradation
  • System Malfunctions

Peach Bottom Atomic Power Station Annex Exelon Nuclear EAL Threshold Values are sorted under common Initiating Conditions (ICs). These ICs can be Symptom- or Event-based, and applicable to all or only designated Operational Conditions

/ Modes OPCONs. The Initiating Conditions (IC) and associated EAL Threshold Values are summarized in the EAL Matrix (Table PBAPS 3-1) according to Recognition Categories.

To aid user in identifying applicable ICs, they are further sorted under the following Event Sub-Categories, and appropriate Mode designator provided:

  • AbnormaiRadiologicalLevels/Effluents ("R")

- Radiological Effluents

- Abnormal Radiation Levels

- Coolant Activity

  • Fission Product Barrier Degradation ("F")

- Fuel Clad

- Reactor Coolant System, referred to as "RCS"

- Primary Containment, referred to as "Containment"

  • System Malfuncions ("M")

- Loss of AC Power

- Loss of DC Power

- Failure of Reactor Protection System

- Decay Heat Removal

- Loss of Annunciators

- RCS Leakage / RPV Draindown

- MSL Break (with Isolation)

- Loss of Communications

- Technical Specifications

- Irradiated Fuel Accidents

  • Hazards and Other Conditions ("H")

- Security Events

- Control Room Evacuation

- Natural or Man-Made Events

- Fire / Explosion

- Toxic or Flammable Gases

- Discretionary An emergency is classified by assessing plant conditions and comparing abnormal conditions to ICs and Threshold Values for each EAL, based on the designated Operational Condition (MODE). Modes 1 through 5 are defined in the Technical Specifications for Units 2 and 3 based on Reactor Mode Switch Position specific plant conditions. "Defueled" Mode was established for classification purposes under NUMARC/NESP-007 to reflect conditions where all fuel has been removed from the Reactor Pressure Vessel.

Poarh Rnffnm AMmir Pnwor Rfafinn Annwr Exeplan Nuripar P- hfnfn Afma Pnwp 1 -F tfinAn 1n u-1 MODE TITLE 1 Power Operation 2 Start-up 3 Hot Shutdown 4 Cold Shutdown 5 Refueling D Defueled The EAL Matrix is designed to provide an evaluation of the Initiating Conditions from the worst conditions (General Emergencies) on the left to the relatively less severe conditions on the right (Unusual Events). Evaluating conditions from left to right will reduce the possibility that an event will be under classified. All Recognition Categories should be reviewed for applicability prior to classification.

An appropriate EAL numbering system is provided as a user aid. ICs are coded with a two letter and one number code. For example: HA I The first letter is the Recognition Category designator. In this case, H stands for "Hazards and Other Conditions". The second letter is the Classification Level: "U" for Unusual Event, "A" for Alert, "S" for Site Area Emergency, and "G" for General Emergency. The number is a sequential number for that Recognition Category series. All Initiating Conditions, which are describing the severity of a common condition (series), will have the same number (e.g. HAI, HA2, etc.).

A Fission Product Barrier (FPB) Table is provided as a subset to the Recognition Category "F" (FPB Degradation) of the EAL Matrix. This table is used to determine the integrity of the Fuel Clad, RCS and Containment Barriers based on EAL Threshold values established in accordance with NUMARC/NESP-007 (e.g., Intact, LOSS, or POTENTIAL LOSS).

3.2 EAL Technical Basis Table PBAPS 3-2 serves as the Technical Basis for the EAL Matrix. The table consists of the following sections for each Initiating Condition (IC), sorted by Recognition Category:

  • Initiating Condition
  • Threshold Value
  • Mode Applicability
  • Basis (includes deviations from NUMARC/NESP-007 as appropriate)

Table PBAPS 3-2 provides the EAL user with the background and justification behind the EAL Threshold Values identified using the guidance set forth in NUMARC/NESP-007.

For a radiological liquid release, the emergency action level is based on calculated off-site dose from a chemistry sarnple. Shift Supervision utilizes emergency response procedures to notify risk counties and to obtain river water samples.

    • n AwvoFw1nNui.a, P.YWaxn" Valield-air 3.3 General EAL Implementation Philosophy A broad spectrum of discretion in classifying events is provided in the "Discretionary" category under Hazards and Other Conditions and the Fission Product Barrier Matrix in Table PBAPS 3-1. In using the "Discretionary" category and in classifying emergencies under circumstances which are not a straight-forward use of the EAL's, ERO members should be mindful than an approach is needed which is conservative with respect to public, plant, and personnel safety and with respect to ensuring the adequacy of personnel and technical support. Conservative decisions must be made if the ED has any doubt regarding the health and safety of the public.

Declaring an Unusual Event provides the Company and off-site agencies the opportunity for early information regarding the event and for early activation of resources and may be considered a "no consequence decision." Conversely, not declaring an Unusual Event when there are credible (but, not clear) bases for doing so, would appear to be less than open or candid and could have serious adverse consequences. Although the consequences of declaring an Unusual Event are limited, inappropriate classifications do not accurately indicate the significance of the event to the public and emergency responders and should be avoided.

At the Alert, Site Area and General Emergency levels, clearly the threat to the plant and to the public is at a heightened level. Rapid application of resources and preparation for providing for the public health and safety are appropriate. Because of the magnitude of resource mobilization and the potential disruption of normal public activities, an overly conservative or an inappropriately early declaration of these levels is not advisable.

Events that meet the Emergency Action Level criteria for event declaration, but which are terminated before they are identified and declared, should still be classified and reported, but not declared to implement the Emergency Plan.

All EALs may not consider trends, rates of change, or status changes in equipment availability. In the event of rapidly changing parameters trending toward an increased emergency classification, it may be appropriate to decide that the higher level EAL will be exceeded and escalate the classification early. In the event of trends toward a decreased emergency classification, parameter values must be below the EALs to de-escalate.

In the event of a "spike" which rapidly exceeds and then exits an EAL condition, entry into the Emergency Plan or escalation to the higher classification "in retrospect" is not appropriate unless the "spike" is indicative of continuing degrading conditions which will lead to an escalated emergency classification level. This statement does not apply if the EAL includes a "spike". Spurious alarms or parameters, which are known to be invalid indicators of actual plant conditions or of the emergency classification, should not be used to declare emergency classifications.

Site Boundary - For classification and dose projection purposes, the Site Boundary is the Exclusion Area Boundary, a 2700 foot radius around the plant. The actual boundary is specified in the ODCM.

Total Effective Dose Equivalent (TEDE) The sum of the deep dose equivalent (for external exposure) and the committed effective dose equivalent (for internal exposure) and 4 days of deposition exposure.

Committed Dose Equivalent (CDE) The Dose Equivalent to organs or tissues of reference that will be received from an intake of radioactive material by an individual during the 50-year period following the intake. Thyroid values are taken from EPA400, Table 5-4 to be consistent with the NRC RASCAL dose assessment program used by the Pennsylvania Emergency Management Agency (PEMA) / Bureau of Radiation Protection (BRP). Actual meteorology is used, since it gives the most accurate dose projection.

Table R1:

Effluent Monitors - Classification is based on the instantaneous release rate value if NO dose projections can be performed or verified within 15 minutes of meeting or exceeding the specified Release Rate value.

For a gaseous release from the Torus Vents, if a valid effluent monitor reading (Unit 2: RIS-80291 or Unit 3: RIS-90291) indicates "off-scale high" (> 1.OE+7 cpm) AND field monitoring teams are not available to immediately confirm actual offsite dose below Table R-2 thresholds, then DECLARE a General Emergency classification. Since effluent monitor is "off-scale high", Table R-2 projected offsite dose thresholds cannot be confirmed using DAPAR for the Torus Vents.

NOTE: (For calculation basis purposes) The threshold value for the Torus Vent was calculated at 6.95E+9 cpm, which is "Off-Scale High" (! I.OE+7 cpm).

Monitor indications are calculated using the computerized dose model with UFSAR (gap release) source terms applicable to each monitored pathway in conjunction with annual average meteorology per NUMARC/NESP-007 (Revision 2). Calculations assume:

Unplanned - Any release for which a radioactive discharge permit was not prepared, or a release that exceeds the conditions (e.g., minimum dilution flow, maximum discharge flow, alarm set points, etc.)

on the applicable permit It is not intended that the release be averaged over 15 minutes. A release of this greater magnitude that cannot be terminated in 15 minutes represents an uncontrolled situation that is an actual or potential substantial degradation of the level of safety of the plant. The degradation in plant control implied by the fact that the release cannot be terminated in 15 minutes is the primary concern.

Further, the Emergency Director should not wait until 15 minutes has elapsed, but should declare the event as soon as it is determined that the release duration has or will likely exceed 15 minutes, unless release rate confirmation (sample, field survey or dose projection) is likely within this 15 minute period.

Table RI:

Effluent Monitors - EAL thresholds are based on 200 times the ODCM limits. For event classification purposes, the HI-HI Radiation alarms for the Main Stack and Vent Stacks are used to represent the ODCM limit. These alarm set points are using the calculation methodology as outlined in Sections 2.2 of the ODCM, which uses the highest annual average X/Q value for the designated sectors in accordance with NUMARC/NESP-007 (AA1). The HI Radiation alarm set points are also set conservatively to indicate when a release may approach ODCM limits assuming multiple release points.

Table R2:

It is intended that the event be declared as soon as it is determined that the release will exceed two hundred times ODCM for greater than 15 minutes.

Unplanned - Any release for which a radioactive discharge permit was not prepared, or a release that exceeds the conditions (e.g., minimum dilution flow, maximum discharge flow, alarm set points, etc.)

on the applicable permit Unplanned releases in excess of two times the site ODCM that continue for 60 minutes or longer represent an uncontrolled situation and hence, a potential degradation in the level of safety. The final integrated dose (which is very low in the Unusual Event emergency class) is not the primary concern here; it is the degradation in plant control implied by the fact that the release was not isolated within 60 minutes. Therefore, it is NOT intended that the release be averaged over 60 minutes. For example, a release of 4 times ODCM limits for 30 minutes does not exceed this EAL. Further, the Emergency Director should NOT wait until 60 minutes has elapsed, but should declare the event as soon as it is determined that the release duration has or will likely exceed 60 minutes, if it is unlikely that an ODCM calculation can be performed within 60 minutes of exceeding the EAL threshold.

Table Rl:

Effluent Monitors - EAL thresholds are based on two times the ODCM limits. For event classification purposes, the HI-HI Radiation alarms for the Main Stack and Vent Stacks are used to represent the ODCM limit. These alarm set points are using the calculation methodology as outlined in Sections 2.2 of the which uses the highest annual average X/Q value for the designated sectors in accordance with NUMARC/NESP-007 (AUI). The HI Radiation alarm set points are also set conservatively to indicate when a release may approach ODCM limits assuming multiple release points.

Table R2:

It is intended that the event be declared as soon as it is determined that the release will exceed two times ODCM for greater than 60 minutes.

APLIAB'LITY ALL BAISJR (Rfeene This EAL addresses elevated radiation levels that impede necessary access to operator stations, or other areas containing equipment that must be operated manually in order to maintain safe operation or to perform a safe shutdown. The concern of the EAL is a loss of control of radioactive material causing high radiation levels. As such, this EAL is not intended to apply to anticipated temporary increases in radiation levels due to planned events (e.g., incore detector movement, radwaste container movement, depleted resin transfers, controlled movement of radiological sources, or expected increases in area radiation levels due to normal operation of plant systems / components, etc.).

The impaired ability to operate the plant is to be considered as the actual or potential substantial degradation of the level of safety of the plant The cause of the rise in radiation levels is not the major concern of this EAL. For example, a dose rate of 15 mR/hr in the control room or hi radiation monitor readings may also be indicative of high dose rates in the containment due to a LOCA. In this latter case, the fission product barrier table may indicate a SAE or GE. This EAL could result in declaration of an Alert at one unit due to a radioactivity release or radiation shine resulting from a major accident at the other unit.

Threshold Value I - The value of 15 mRem/hr is derived from the general design criteria (GDC) value of 5 REM in 30 days with adjustment for expected occupancy times. Although Section HII.D.3 of NUREG-0737 "Clarification of TMI Action Plan Requirements" provides that the 15 mRem/hr value can be averaged over the 30 days, the value is used here without averaging, as a 30 day duration implies an event potentially more significant than an ALERT.

Plant normal and emergency procedures may be implemented without requiring access to any areas except the Control Room and Central Alarm Station to be continuously occupied. The Radwaste Control Room is not required to be continuously occupied in order to maintain plant safety functions since inputs to radwaste will be isolated with a secondary containment isolation and releases can only be performed manually.

Threshold Value 2 - Areas requiring infrequent access and dose rate values are based on those specified in procedures SE-1 or SE-10. EAL is applicable only when procedures SE-1 or SE-10 direct access, in other words, when you are in those procedures. Therefore, if you where in procedures SE-I or SE-10 and you needed to direct access to a particular area and at the time radiation levels were > 5 R/hr, classification under this EAL is appropriate. Just having radiation levels > 5 R/hr in those areas defined in SE-1 or SE-10, when access is not directed per procedure, does not warrant classification under this EAL.

The single value of 5 R/hr was selected because it is based on radiation levels which result in exposure control measures intended to maintain doses within normal occupational exposure guidelines and limits (i.e., 10 CFR 20), and in doing so, will impede necessary access. Stay times for levels up to that value are, generally several minutes, enough time to enter an area and manually operate the equipment. Dose rates > 5 R/hr will impede necessary access.

Unplanned - Not the result of an intended evolution and requiring corrective or mitigative actions.

Normal Levels - Normal radiation levels can be considered as the highest reading in the past 24-hour period, excluding the current peak value, as determined by recorder charts, surveys, logs, etc.

Classification of an UNUSUAL EVENT is warranted as a precursor to more serious events. The concern of this EAL is the loss of control of radioactive material representing a potential degradation of the level of safety of the plant. The Threshold Value tends to have a long lead-time relative to a radiological release and thus the threat to public health and safety is very low. In light of the elevated dose rates the Emergency Director should evaluate how these conditions will affect the other unit.

1,2,3 Threshold Value 1: The steam jet air ejector discharge (Off-Gas) radiation monitor in the Control Room would be one of the first indicators of a degrading core. This instrument takes a sample before the recombiner. This indicator of elevated activity is equivalent to Technical Specification limit and is considered to be a precursor of more serious problems.

Threshold Value 2: Main Steam Line (MSL) Hi-Hi Radiation alarm > 10 times normal full power background (NFPB), may be indicative of minor fuel cladding degradation. The MSL Hi-Hi radiation condition requires a manual Main Steam Isolation Valve (MSIV) closure and a reactor scram. This transient may result in the introduction of fission product gases (previously contained in the gap area) to be suddenly released into the coolant due to the rapid down power transient and subsequent collapse of voids in the coolant.

This level of steam line activity is indicative of the release of gap activity to the coolant, rather than a major failure of the fuel clad. However, the mechanics that caused MSL radiation to rise to this level indicate there are a degradation of Fuel Clad integrity.

This EAL is NOT intended to apply to cases caused by resin intrusion or other known factors that are not directly indicative of fuel cladding degradation, but rather coolant chemistry issues.

This event will escalate to a Site Area Emergency based on a MSL break per EITHER the Fission Product Barrier Matrix (2.d.1 & 3.d.1) for an unisolable break, OR an Alert based on MA8 for an isolable MSL break scenario.

DEVIATION: The MODE applicability [1,2,3] is a deviation from NUMARC [all] in that, the SJAE Radiation Monitor and Main Steam Line Radiation Monitors will only be a valid indication of Fuel Clad Degradation in those Modes. There are no other monitors, which can be used as an indicator of Fuel Clad Degradation.

Coolant activity in excess of Technical Specifications (> 4 RCi/gm) is considered to be a precursor of more serious problems. The Technical Specification limit reflects a degrading or degraded core condition. This level is chosen to be above any possible short duration spikes under normal conditions.

An Unusual Event is only warranted when actual fuel clad damage is the cause of the elevated coolant sample (as determined by laboratory confirmation). However, fuel clad damage should be assumed to be the cause of elevated Reactor Coolant activity unless another cause is known, e.g., Reactor Coolant System chemical decontamination evolution (during shutdown) is ongoing with resulting high activity levels.

This event will be escalated to an Alert when Reactor Coolant activity exceeds 300 RCi/gm Dose Equivalent Iodine 131 per Fission Product Barrier Matrix I.d. 1.

Conditions / events required to cause the loss of 2 Fission Product Barriers with the potential loss of the third could reasonably be expected to cause a release beyond the immediate site area exceeding EPA Protective Action Guidelines.

Guidance for development of this EAL was taken from Recognition Category F in the NUMARC/NEI Methodology for Development of Emergency Action Levels.

A barrier LOSS shall also constitute a POTENTIAL LOSS for classification purposes.

NOTES:

1. Although the logic used for these initiating conditions appears overly complex, it isnecessary to reflect the following considerations:
  • The Fuel Clad barrier and the RCS barrier are weighted more heavily than the Primary Containment barrier. Unusual Event Initiating Conditions ([Cs) associated with RCS and Fuel Clad barriers are addressed under the other plant condition EALs.
  • At the Site Area Emergency level, there must be some ability to dynamically assess how far present conditions are from General Emergency. For example, if the Fuel Clad barrier and RCS barrier "Loss" EALs existed, this would indicate to the Emergency Director that, in addition to offsite dose assessments, the ED must focus on continual assessments of radioactive inventory and containment integrity. If, on the other hand, both Fuel Clad barrier and RCS barrier "Potential Loss" EALs existed, the Emergency Director would have more assurance that there was no immediate need to escalate to a General Emergency.

The ability to escalate to higher emergency classes as an event gets worse must be maintained. For example, RCS leakage steadily rising would represent an increasing risk to public health and safety.

2. Fission Product Barrier ICs must be capable of addressing event dynamics. An IMMINENT (i.e., within I to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />) Loss or Potential Loss should result in a classification as if the affected threshold(s) are already exceeded, particularly for the higher emergency classes.
3. The Fuel Clad barrier is the cladding tubes that contain the fuel pellets.
4. The RCS Barrier is the reactor coolant system pressure boundary and includes the reactor vessel and all reactor coolant system piping up to the isolation valves.
5. The Primary Containment Barrier includes the drywell, the torus, their respective interconnecting paths, and other connections up to and including the outermost containment isolation valves.
6. If a "Loss" condition is satisfied, the "Potential Loss" category can be considered satisfied. This is also applicable to conditions where there is a "Loss" indication with no corresponding "Potential Loss" condition.
7. For all conditions listed in Fission Product Barrier Table, the barrier failure column is only satisfied if it fails when called upon to mitigate an accident. For example, failure of both containment isolation valves to isolate with a downstream pathway to the environment is only a concern during an accident If this condition exists during normal power operations, it will be an active Technical Specification Action Statement. However, during accident conditions, this will represent a breach of Primary Containment.

LOSS - IThreshold Value #11 Value of -195 inches corresponds to the level, which is used in the TRIP guidance to indicate challenge of core cooling. This is the Minimum Steam Cooling RPV Water Level, and as such, is the lowest RPV level at which the submerged portion of the core will generate sufficient steam to prevent any clad in the uncovered portion of the core from exceeding 15000F. This RPV level is utilized to preclude fuel damage when RPV level is below the Top of Active Fuel (TAF).

Core submergence is the preferred method of core cooling and as such, the failure to re-establish RPV water level above the top of active fuel for an extended period of time could lead to significant fuel damage. RPV level < -195" could be indicative of a large break Loss Of Coolant Accident (LOCA) where ECCS Systems are designed to maintain level at 2/3 core height, or a small LOCA with the inability of emergency core cooling systems to reflood the RPV.

POTENTIAL LOSS - [Threshold Value #21 Core submergence is the preferred method of core cooling, and as such, the failure to re-establish RPV water level above TAF for an extended period of time could lead to significant fuel damage.

A level of < -172 inches also corresponds to the EAL for a RCS Barrier LOSS (IC RCS 2.a l). Thus, this EAL indicates a LOSS of RCS barrier and a POTENTIAL LOSS of the Fuel Clad Barrier.

LOSS - The intent is not to verify criteria used in calculation (e.g., release of reactor coolant into drywell),

but rather to classify once EAL threshold value is reached or exceeded. Reactor coolant concentrations of this magnitude are several times larger than the maximum concentrations (including iodine spiking) allowed within technical specifications and are therefore indicative of fuel damage. This value is higher than that specified for RCS barrier under RCS 2.b.1. Thus, this EAL indicates a loss of both Fuel Clad barrier and RCS barrier.

[Calculation Basis] The 7.8E+4 R/hr reading on a drywell high range gamma radiation monitor RI-8(9)103A,B,C,D is a value which indicates the release of reactor coolant, with elevated activity indicative of fuel damage, into the drywell. The reading was calculated assuming an instantaneous release and dispersal of the Reactor Coolant noble gas and iodine inventory into the Primary Containment (direct reading not shine) at a coolant concentration of 300 PlCi/gm Dose Equivalent Iodine 131.

This calculation is as follows:

Using Curve 3 [1%] of Figure 4-1 of the Peach Bottom Annex "Containment Radiation Monitor Dose Rate Curves":

Time after Shutdown = 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (more conservative due to lower value for EAL) 1% fuel clad damage: dose rate = 30,000 R/hr Extrapolating to 2.6%: (30,000 Rhr/10%)(2.6) = 78,000 R/hr 2.6% clad damage is based upon NUREG-1228 core damage analysis, and by virtue of its release into containment, the loss of the Reactor Coolant barrier (detailed calculations are contained in the Basis for Fission Product Barrier IC FC 1.d.1).

1,2,3 LOSS - Core submergence is the preferred method of core cooling, and as such, the failure to re-establish RPV water level above TAF for an extended period of time could lead to significant fuel damage.

A level of < -172 inches also corresponds to the EAL for a Fuel Clad Barrier POTENTIAL LOSS (IC FC I.a.2). Thus, this EAL indicates a LOSS of RCS barrier and a POTENTIAL LOSS of the Fuel Clad Barrier.

POTENTIAL LOSS - Inability to determine Reactor Pressure Vessel (RPV) level prevents assurance of adequate core cooling by methods that rely on being able to determine RPV water level (i.e., submergence or Minimum Steam Cooling RPV Water Level). TRIP procedures will provide criteria and strategies when RPV level CANNOT be determined.

LOSS - The intent is not to verify criteria used in calculation (e.g., RCS breach), but rather to classify once EAL threshold value is reached or exceeded. This reading is less than that specified for a Fuel Clad Barrier LOSS (under IC Fuel Clad L.b. 1). Thus, this EAL would be indicative of a RCS leak only. If the radiation monitor reading rises to that value specified under IC Fuel Clad L.b.1, Fuel Clad damage would also be indicated.

[Calculation Basis] The 15 R/hr reading is a value, which indicates the release of reactor coolant to the drywell. The value assumes an instantaneous release and dispersal of the reactor coolant noble gas and iodine inventory associated with concentrations corresponding to 0.001% Total Isotopic Distribution (I1D) into the drywell atmosphere.

Using Curve 3 [1%] of Figure 4-1 of the Peach Bottom Annex "Containment Radiation Monitor Dose Rate Curves":

1,2,3 LOSS - The 2.0 psig drywell pressure is based on the drywell high pressure alarm set point and indicates a LOCA. If drywell pressure exceeds 2.0 psig, there is indication that a leak of sufficient magnitude exists l that prevents drywell pressure stabilization.

Cycling of safety relief valves to reduce primary system overpressure when no fuel damage is indicated, is NOT considered reactor coolant leakage.

Primary containment pressure rises due solely to loss of containment heat removal capability are also NOT considered to exceed this threshold.

POTENTIAL LOSS- NONE DEVIATION: The EAL, as stated in NUMARC/NESP-007, contains only the diywell pressure. A qualifier was added as a human factor reminder to the Emergency Director that use of this EAL is for accident scenarios only:

"AND Indication of a RCS leak inside drywell" Thus, a Drywell Pressure rise due to the loss of Dxywell Cooling will not require an emergency classification.

LOSS - [Threshold Value #11 Hi Steam Flow and Hi Steam Tunnel Temperature Annunciators are both indicators of a Main Steam Line Break. Both parameters will cause an isolation of the MSIV's. Should both valves in any one line fail to isolate, this event would be also considered a LOSS of Primary Containment (perIC 3.d. 1) and appropriately classified as a Site Area Emergency.

Direct report of steam release is meant to provide an alternate means of classification if the Hi Steam Flow Annunciator or the Hi Steam Tunnel Temperature Annunciator fails to operate and the visual observation of conditions indicates a Main Steam Line Break in the judgment of the Emergency Director. This is not meant to cause a declaration based on leaks such as valve packing leaks where the consequences offsite would be negligible.

Refer to MA8 for classification of an Alert due to an isolable Main Steam Line Break.

Design basis accident analyses of a Main Steam Line Break outside of secondary containment shows that even if MSIV closure occurs within design limits, dose consequences offsite from a "puff" release would be in excess of 10 mRem.

LOSS - [Threshold Value #21 Loss of the RCS Barrier based on an open safety relief valve (SRV) is dependent on other events. If an SRV is stuck open or cycling and no other emergency condition exists, an emergency declaration is not appropriate. However, if the fuel is damaged and the relief valve is allowing the fission products to escape into the Drywell (Containment), a LOSS of the RCS Barrier has occurred.

POTENTIAL LOSS - [Threshold Value #31 The potential loss of RCS based on leakage >50 gpm is set at a level indicative of a small breach of the RCS but which is well within the makeup capability of normal and emergency high pressure systems. Core uncovery is not a significant concern for a 50 gpm leak; however, a break propagation leading to a significantly larger loss of inventory is possible. RCS leakage is measured by the normal primary system leakage monitoring system and is leakage into the drywell. Under certain conditions, this system may be isolated due to elevated drywell pressure caused by the leak. In that case, a LOSS of RCS will be indicated and this "potential loss" of RCS would not impact the classification.

Inventory loss events, such as a stuck open SRV, should not be considered when referring to "RCS leakage" because they are not indications of a break, which could propagate.

POTENTIAL LOSS - [Threshold Value #41 Potential loss of RCS based on primary system leakage outside Containment is determined from site-specific area temperatures or radiation levels per T-103, which indicate a direct path from the RCS to areas outside primary containment. Initiation of a SCRAM per T-103 prior to reaching the Action Levels for area temperature and radiation meets the intent of EAL.

T-103 Action Levels based on area water level (Table SC/L5 2) are evaluated separately for an Alert classification under IC HA3 (Natural or Destructive Phenomena Affecting a Vital Area).

  • Unisolable - Refers to a leak that cannot be isolated from the Control Room. When evaluating this EAL for unisolable primary system leakage, it is appropriate to attempt isolation from the Control Room prior to classification.
  • Primary System - The pipes, valves and other equipment which connect directly to the RPV such that a reduction in RPV pressure will cause a drop in the flowrate of steam or water being discharged through a break in the system.
  • Primary System Leakage - In general, multiple indications should be used to determine if a primary system is discharging outside Primary Containment. For example, a high area radiation condition does not necessarily indicate that a primary system is discharging into the Reactor Building since this may be caused by radiation shine from nearby steam lines or the movement of radioactive materials. Conversely, a high area radiation condition in conjunction with other indications (e.g.

room flooding, high area temperatures, reports of steam in the Reactor Building, an unexpected rise in Feedwater flowrate, or unexpected Main Turbine Control Valve closure) may indicate that a primary system is discharging into the Reactor Building.

LOSS - NONE POTENTIAL LOSS - The intent is not to verify criteria used in calculation, but rather to classifir once EAL threshold value is reached or exceeded.

[Calculation Basis] A drywell high range gamma radiation monitor RI-8(9)103AB,C,D reading > 6.0E+5 R/hr indicates significant fuel damage, well in excess of that required for the loss of the RCS and Fuel Clad. As stated in Section 3.8 of NUMARC/NESP-007, a major release of radioactivity requiring offsite protective actions from core damage is not possible unless a major failure of fuel cladding allows radioactive material to be released from the core into the reactor coolant. Regardless of whether containment is challenged, this amount of activity in containment, if released, could have such severe consequences that it is prudent to treat this as a potential loss of containment, such that a General Emergency declaration is warranted. NUREG-1228, "Source Estimations During Incident Response to Severe Nuclear Power Plant Accidents," indicates that such conditions do not exist when the amount of clad damage is less than 20%.

The reading was calculated assuming an instantaneous release of the Reactor Coolant volume into the Primary Containment (direct reading not shine) where the value corresponds to a release of approximately 20% of the gap region. This calculation is as follows:

Using Curve 3 [1%] of Figure 4-1 of the Peach Bottom Annex "Containment Radiation Monitor Dose Rate Curves":

LOSS - [Threshold Value #21 Drywell pressure should rise as a result of mass and energy release into the containment from a Loss of Coolant Accident (LOCA). Thus, Drywell pressure NOT rising under these conditions indicates a breach of containment integrity.

POTENTIAL LOSS - [Threshold Value #31 A Drywell pressure 49 psig is equal to the peak pressure expected from a Design Basis Accident (DBA)LOCA and is based on the containment/drywell design pressure. If the containment design pressure is exceeded this represents a challenge to the containment structure because assumptions used in the accident analysis are no longer valid and an unanalyzed condition exists. This constitutes a potential loss of the containment barrier even if a breach has NOT occurred.

When evaluating this EAL for Torus level outside of the Heat Capacity Temperature Limit Curve, High or Low, it is appropriate to consider the operation to be on the "UNSAFE" side.

Loss of all AC power compromises all plant safety systems requiring electric power including RHR, ECCS, Containment Heat Removal and the Ultimate Heat Sink. Prolonged loss of all AC power will lead to loss of fuel clad, RCS, and containment. The two hours to restore AC power is based on the site blackout coping analysis as described below. Although this IC may be viewed as redundant to the Fission Product Barrier Degradation IC, its inclusion is necessary to better assure timely recognition and emergency response.

10 CFR 50.2 defines Station Blackout (SBO) as complete loss of AC power to essential and non-essential buses. SBO does not include loss of AC Power to busses fed by station batteries through inverters, nor does it assume a concurrent single failure or design basis accident.

Successful extended SBO coping depends on ability to keep HPCI/RCIC available for injection, and ability to maintain RPV depressurized for low pressure injection should HPCI and RCIC become unavailable. 125V DC provides control power for HPCI, RCIC and SRVs.

The criteria for "Restoration of at least one 4 KV emergency bus in < 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />" is based on Peach Bottom Calculation PE-017. From the Peach Bottom DBD, "The 125/250 VDC system battery capacity requirements are based on supplying DC power with the batteries as the sole source for two (2) hours following a LOOP / LOCA."

The significance of a station blackout relative to the loss of fission product release barriers is that all three barriers will eventually be lost due to the inability to remove heat from the fuel and the containment. Although the RCS will be intact the longest, eventually SRVs will operate in the relief mode due to RPV over-pressurization and if the containment has already failed then there is a direct bypass of the RCS boundary.

1,2,3 BASI(Reerenc)

The reduction of available reliable power sources to a condition where ANY additional single failure will result in a station blackout is a substantial degradation in the level of safety of the plant. That is, the Unit is down to its last source of AC power. Loss of the single power supply would escalate to a SITE AREA EMERGENCY via IC MS 1.

This EAL is intended to provide an escalation from "Loss of offsite Power for greater than 15 minutes."

This condition is a degradation of the offsite and onsite power systems such that any additional failure would result in a station blackout. Fifteen (15) minutes has been selected to allow adequate time to cross tie or address diesel generator failures and to exclude transient or momentary power losses.

However, an Alert should be declared in less than 15 minutes if it can be determined in less than 15 minutes that the power loss is not transient or momentary.

Depending on the 4 KV AC bus that remains energized there is a dispanty in the systems that may be available. The ability to remove heat from the containment via Torus cooling may be lost due to the need to operate the remaining available RHR pump in other than Torus cooling (e.g., LPCI). As such there is a decrease in the systems available to remove heat transferred to the containment and there is an ongoing release of energy from the reactor to the containment (via SRVs, HPCI and/or RCIC operation). The ability to cool the nuclear fuel, remove decay heat, and control containment parameters is severely limited. Should equipment be unavailable prior to the loss of power, functions necessary to maintain the plant in a cold shutdown condition may be threatened.

Unplanned - Not the result of an intended evolution and requiring corrective or mitigative actions This EAL addresses the loss of offsite AC power supplying the station. OfMite power is fed through 2 and 3 Startup and Emergency Aux. Transformers and 343 Startup Transformer. Loss of offsite power will cause a reactor scram and a containment isolation. All four (4) emergency Diesel Generators will be available to carry the essential loads for each unit (the four Diesel Generators are shared between each unit). Balance of Plant systems that would assist in plant operations (i.e., condensate pumps, etc.)

may be unavailable due the loss of power.

Prolonged loss of AC power reduces required redundancy and potentially degrades the level of safety of the plant by rendering the plant more vulnerable to a complete Loss of AC Power (Station Blackout).

Fifteen minutes was selected as a threshold to allow adequate time to cross tie or address diesel generator failures and to exclude transient or momentary power losses.

The Emergency Director must also consider the impact to the unaffected unit due to the loss of power to balance of plant equipment on common or shared systems.

Escalation of this event to an Alert would be based on having a loss of all offsite AC power coincident with onsite AC power being reduced to a single power source in Modes 1, 2, and 3 or having a loss of all offsite and onsite AC power in Modes 4 or 5.

The purpose of this EAL is to recognize a loss of DC power compromising the ability to monitor and control the removal of decay heat during Cold Shutdown or Refueling operations. This EAL is intended to be anticipatory in as much as the operating crew may not have necessary indication and control of equipment needed to respond to the loss.

107.45 VDC bus voltage is based on the minimum bus voltage necessary for the operation of safety related equipment. The value of 107.5 VDC will be used for human factors concerns. This voltage value incorporates a margin of at least 15 minutes of operation before the onset of inability to operate those loads.

Routinely, plants will perform maintenance on a Train related basis during shutdown periods. It is intended that the loss of a required train be considered. If this loss results in the inability to maintain cold shutdown, the escalation to an Alert will occur.

In addition, control room instrumentation indicates that operation is on the "UNSAFE" side of the HCTL Curve (T-102, T/T-1) or RPV level is < -195 inches. When Torus level is outside of the Heat Capacity Temperature Limit (HCTL) Curve (High or Low), it is appropriate to consider operation to be on the "UNSAFE" side.

1. RPS set point has been exceeded for an automatic SCRAM AND Failure of automatic RPS to achieve a state in which the reactor is shutdown under all conditions without boron 1,2 BAIS(References)

This EAL is not applicable if a manual scram is initiated and no RPS set points are exceeded. Taking the mode switch to shutdown is considered a manual scram action. Note that although placing the Mode Switch in "shutdown" is a manual scram action, when the Mode Switch passes through the "startup / hot standby" position the Nuclear Instrumentation Scram Setpoint is lowered. If reactor power is greater than the setpoint, an automatic scram will be initiated. If the RPS then fails to initiate a scram, then this should be evaluated as an automatic RPS set point being exceeded and a failure of the automatic scram.

Entry into this EAL is based on a reactor parameter actually exceeding a RPS set point and the reactor is not brought to a state in which the reactor is shutdown under all conditions without boron injection and maintained at that state with automatic RPS functions. The parameter must exceed the RPS set point by a significant margin eliminating minor set point drifts, which are accounted for in the Technical Specification Margin of Safety. Subsequent manual scram actions were successful in bringing the reactor to a state in which the reactor is shutdown under all conditions without boron injection.

Confirmation indications include control room annunciators, APRM/WRNM power level, Reactor Period, and Control rod position indication.

When partial control rod insertion occurs following a scram signal (either manual or automatic) judgment should be applied as to whether the Reactor will remain "Shutdown Under All Conditions Without Boron" and if classification should occur. Multiple control rods failing to insert beyond the Maximum Subcritical Banked Withdraw Position (MSBWP) may require actions to fully insert the control rods. TRIP guidance will govern the insertion of these control rods.

The loss of heat removal function is indicated by T-102 TlT leg requiring an Emergency Blowdown, which is directed when the Heat Capacity Temperature Limit (HCTL) curve is exceeded.

The EAL is concerned with Torus temperature. It is not appropriate to make a Site Area Emergency classification for the condition where the T-102 Torus Level (T/L) leg alone directs a T-1 12 Emergency Blowdown since the Emergency Blowdown is performed PRIOR to those Torus levels which may cause a loss of containment capability due to uncovering downcomers or excessive SRV tailpipe stresses.

Under these conditions, there is an actual major failure of a system intended for protection of the public.

Uncontrolled - A temperature rise that is not the result of a planned evolution This EAL addresses complete loss of functions required for core cooling during refueling and cold shutdown modes. A loss of Technical Specifications components is paired with exceeding temperature limits to acknowledge additional plant capabilities to maintain plant cooling. Escalation to Site Area Emergency or General Emergency would be via Effluent Release/n-Plant Radiation or Emergency Director Judgment ICs.

The statement "Temporary Loss of ALL Tech Spec Required Decay Heat Removal Systems" is intended to represent a complete loss of functions available, or an inadequate ability, to provide core cooling during the Cold Shutdown and Refueling Modes, including alternate decay heat removal methods. This EAL allows for actions taken in ON-125, "Loss of Shutdown Cooling - Procedure," to reestablish RHR in the Shutdown Cooling Mode or provide for alternate methods of decay heat removal, with the intent of maintaining RCS temperature below 2120 F.

For loss of an in-service Decay Heat Removal system with other decay heat removal methods available, actions taken to provide for restoration of a decay heat removal function may require time to implement. If the event results in RCS temperature "momentarily" (for less than 15 minutes) rising above 212"F with heat removal capability restored, Emergency Director/Shift Management judgment will be required to determine whether heat removal systems are adequate to prevent boiling in the core and restoration of RCS temperature control.

Momentary (not to exceed 15 minutes) unplanned excursions above 2120 F, when alternate decay heat removal capabilities exist, should not be classified under this EAL.

The EAL guidance related to uncontrolled temperature rise is necessary to preserve the anticipatory philosophy of NUREG-0654 for events starting from temperatures much lower than the cold shutdown temperature limit.

This EAL is concerned with the ability to keep the reactor core temperature less than 212 'F. The criteria of uncontrolled Reactor Coolant temperature rise > 212 'F is met as soon as it becomes known that sufficient cooling cannot be restored in time to maintain the temperature < 212 'F, regardless of the current temperature. The inability to establish alternate methods of decay heat removal indicates that either alternate methods are unavailable to cool the core in the RPV or when the steam is transferred to the Torus, Torus cooling is unavailable. Loss of Torus cooling will result in a continuing, uncontrolled rise in reactor coolant temperature.

Special Test Exception 3.10.8 allows for temperature to rise above 212 'F during hydrostatic testing.

The limit of 212 'F in this EAL does not apply under those conditions as that is not an "Uncontrolled Temperature rise."

Escalation to the Site Area Emergency is by EAL MS7, "Loss of Water Level in the Reactor Vessel that has or will uncover Fuel in the Reactor Vessel," or by Effluent Release/ln-Plant Radiation RS 1.

MOST - 75% of safety system annunciators or indicators are lost OR a significant risk that a degraded plant condition could go undetected exists. The use and definition of MOST is not intended to require a detailed count of lost annunciators or indicators but should be used as a guide to assess the ability to monitor the operation of the plant.

UNPLANNED - Loss of annunciators or indicators is NOT the result of scheduled maintenance or testing.

This EAL recognizes the difficulty associated in monitoring conditions without normal annunciators. It is not intended that a detailed count of instrumentation be performed, but by the use of the judgment of the Shift Supervisor as the threshold for determining the severity of the plant conditions. This judgment is supported by the specific opinion of the Shift Supervisor that additional operating personnel will be required to provide increased monitoring of systems needed to safely operate the plant. The Plant Monitoring System (PMS) is available to provide compensatory indication. Fifteen minutes is used as a threshold to exclude transient or momentary power losses. Unplanned loss of annunciators excludes scheduled maintenance and testing activities. Control Room panels with annunciators and direction for response are included in ON-122, Loss of Main Control Room Annunciators.

This EAL is not applicable in cold shutdown or refueling modes due to the limited number of safety systems required for operation.

.A S IS .. .. .... ............

The indicator for "core is or will be uncovered" is Reactor Pressure Vessel Water level below the Top of Active Fuel (TAF), -172 inches as indicated on RPV Fuel Zone Level Instruments LI-2(3)-02-3-091 or LI-2(3)-02-3-113. Core submergence ensures adequate core cooling. When RPV level drops below the top of active fuel, the ability to remove the decay heat generated from the nuclear fuel becomes suspect and the Fuel Clad Fission Product barrier can no longer be considered intact. Sustained partial or total core uncovery can result in the release of a significant amount of fission products to the reactor coolant.

Under the conditions specified by this IC, severe core damage can occur and reactor coolant system pressure boundary integrity may not be assured. It is intended to address concerns raised by NRC Office for Analysis and Evaluation of Operational Data (AEOD) report AEOD/EG09, "BWR Operating Experience Involving Inadvertent Draining of the Reactor Vessel," dated August 8, 1986. This report states:

In broadest terms, the dominant causes of inadvertent reactor vessel draining are related to the operational and design problems associated with the residual heat removal system when it is entering into or exiting from the shutdown cooling mode. During this transitional period, water is drawn from the reactor vessel, cooled by the residual heat removal system heat exchangers (from the cooling provided by the service water system), and returned to the reactor vessel.

First, there are piping and valves in the residual heat removal system, which are common to both the shutdown cooling mode and other modes of operation such as low pressure coolant injection and Torus cooling. These valves, when improperly positioned, provide a drain path for reactor coolant to flow from the reactor vessel to the Torus or the radwaste system. Second, there is no comprehensive valve interlock arrangement for all shutdown cooling. Collectively, these factors have contributed to the inadvertent draining of the reactor vessel.

Thus, declaration of a Site Area Emergency is warranted under the conditions specified by the IC.

Escalation to a General Emergency is via effluent release EAL.

Detection of low levels of leakage while pressurized is utilized to monitor for the potential of catastrophic failures. Leakage not associated with catastrophic failure potential such as SRV leakage, should not be considered in this EAL.

Identified and unidentified Primary System Leakage is measured by the normal primary system leakage monitoring system and is leakage into the drywell.

This EAL is included as an Unusual Event because it may be a precursor of more serious conditions and, as a result, it is considered to be a potential degradation of the level of safety of the plant. The value of 10 gpm unidentified leakage is significantly higher than the expected pressurized leak rate from the reactor coolant system. The 10 gpm value for the unidentified pressure boundary leakage was selected as it is twice the Technical Specification value, indicating an increase beyond that assumed in Safety Analysis. It also is observable with normal control room indications. The EAL for identified leakage is set at a higher value (25 gpm) due to the lesser significance of identified leakage in comparison to unidentified or pressure boundary leakage.

Technical Specification LCO required actions would necessitate a plant shutdown and subsequent depressurization, unless the source of the leak can be isolated, identified, and/or stopped. Actions initiated by plant staff would include close monitoring of the calculated break size such that any sudden or gradual rise in leak rate would be identified. A slow power reduction and gradual depressurization would be necessitated due to the possibility that a sudden power and/or pressure surge could potentially worsen the break or cause a catastrophic failure.

The leak rate of 10 gpm may cause a high drywell pressure indication. Other indications of a leak of this magnitude would include a rise in drywell temperature or radiation.

Hi Steam Flow Annunciator and Hi Steam Tunnel Temperature Annunciator are both indicators of a Main Steam Line Break. Both parameters will cause an isolation of the MSWV's. Should both valves in any one line fail to isolate, this event would be also considered a LOSS of Primiary Containment (per IC 3.d.1) and as loss of RCS (per IC 2.d.1). This would then appropriately be classified as a Site Area Emergency.

Direct report of steam release is meant to provide an alternate means of classification if the Hi Steam Flow Annunciator or the Hi Steamn Tunnel Temperature Annunciator fails to operate and the visual observation of conditions indicates a Main Steam Line Break in the judgment of the Emergency Director. This is not meant to cause a declaration based on leaks such as valve packing leaks where the consequences offsite would be negligible.

Loss of the RCS Barrier due to an unisolable MSL break is covered under Fission Product Barrier Matrix (IC 2.d.1).

DEVIATION: NUMARC/NESP-007. Table 3 (RC Example EAL #1) EAL placed as a separate Alert threshold under previous NRC submittal to cover an isolable MSL break outside secondazy containment. If the Main Steam Line (MSL) isolates as designed, this condition does not constitute a loss of RCS barrier. However, this condition was included as an event-based EAL due to the potential dose consequences associated with this event. This is consistent with the recommendations provided in the Industiy-developed Questions and Answers on NMIARC/NESP-007 guidance, which was endorsed by the NRtC in a letter dated June 10, 1993.

Offsite doses during these accidents would be well below the EPA Protective Action Guidelines and the classification as an Alert is therefore appropriate. This radiation level could also be caused by an inadvertent criticality and is included even though the probability of this event occurring is low.

Radiation levels rise above 500 mR/hr, which were expected during a planned evolution, should not cause an Alert to be declared. Additionally, surveys, which identify "hot spots" greater than 500 mR/hr should not cause an Alert to be declared.

This IC applies to spent fuel requiring water coverage and is not intended to address spent fuel which is licensed for dry storage, which is discussed in NUMARC/NESP-007 IC AU2, "Unexpected Rise in Plant Radiation or Airborne Concentration."

The areas where irradiated fuel is located forms the basis for Table M-6. Unexpected radiation levels, which are at least 100 times higher than the normal background will generally indicate a fuel handling accident or loss of water covering the irradiated fuel. Readings may be from refuel floor Area Radiation Monitors or taken during a qualified radiological survey.

In addition, NRC Information Notice No. 90-08, "Kr-85 Hazards from Decayed Fuel" presents the following in its discussion:

In the event of a serious accident involving decayed spent fuel, protective actions would be needed for personnel on site, while offsite doses (assuming an exclusion area radius of one mile from the plant site) would be well below the Environmental Protection Agency's Protective Action Guides. Accordingly, it is important to be able to properly survey and monitor for Kr-85 in the event of an accident with decayed spent fuel.

Threshold 1: This EAL applies to potential emergency conditions, which might develop during use of the Independent Spent Fuel Storage Installation and dry cask storage system. This EAL provides for an Unusual Event classification, which may be entered in the event that conditions occur which have the potential for damaging or degrading the fuel, but no releases of radioactive material requiring offsite response or monitoring are expected. Consistent with the NUMARC guidance, escalations above the Unusual Event are not warranted.

Accidents associated with the dry cask storage system include natural and man-made events that are postulated to affect the storage system. The limiting impacts to the system include loss of shielding capability and loss of confinement. The loss of shielding results in higher direct radiation to the environment from the cask while the loss of confinement results in a release of materials from within the cask to the environment at a postulated leak rate.

Loss of confinement for the dry storage system is evaluated in TN-68, Safety Analysis Report, Section 7. Two scenarios are considered, one for off-normal conditions and one for hypothetical accident conditions. Dose calculations are included in section 7.3.2.1. In the extremely unlikely event that one of these scenarios did occur, the event would be addressed by the EALs under Category R, "Abnormal Radiological Levels / Effluents".

Loss of shielding for the dry storage system is evaluated in TN-68, Safety Analysis Report, Section 5.

Dose calculations are included in Table 5.1-2 for both normal and accident conditions. The value of 600 mR/hr one foot away OR 1200 mR/hr at the external surface is determined for several reasons.

According to the TN-68, Safety Analysis Report, Table 5.1-2, Summary of Average Dose Rates, the maximum expected surface dose rates will be 529.5 mR/hr (see note 2). Consequently, the value of 1200 mR/hr is sufficiently above normal conditions as to preclude inappropriate classifications.

Also, the value of 1200 mR/hr is sufficiently below the 1467 mR/hr found in Table 5.1-2 for the cask surface radiological reading for accident conditions. Therefore, 1200 mR/hr from a loss of shielding accident would trigger an Unusual Event classification.

DEVIATION: A bomb device discovered within Plant Protected Area and outside the Plant Vital Areas is an Alert declaration as determined per the site Safeguards Contingency Plan and therefore is not included as an Unusual Event in the EAL scheme.

Control - Placing all local control switches in local control necessary for operation from remote panels and the Shift Manager has determined that the systems for controlling reactivity, core cooling and heat sink functions are established.

Transfer of safety system control has not been performed in an expeditious manner but it is unknown if any damage has occurred to the fission product barriers. The 15 minute time limit for transfer of control is based on a reasonable time period for personnel to leave the control room, arrive at the remote shutdown area, and re-establish plant control to preclude core uncovery and/or core damage. During this transitional period the function of monitoring and/or controlling parameters necessary for plant safety may not be occurring and as a result there may be a threat to plant safety.

Control Room evacuation requires establishment of plant control from outside the control room (e.g.,

local control and remote shutdown panel) and support from the Technical Support Center and/or other emergency facilities as necessary. Control Room evacuation represents a serious plant situation since the level of control is not as complete as it would be without evacuation. The establishment of system control outside of the Control Room will bypass many protective trips and interlocks. In addition, many of the instruments and assessment tools available in the Control Room will not be available.

This event will be escalated to a Site Area Emergency if control cannot be reestablished within fifteen minutes.

i ..i Each of these EALs is intended to address events that may have resulted in a plant vital area being subjected to forces beyond design limits, and thus damage may be assumed to have occurred to plant safety systems. The "initial" report should not be interpreted as mandating a lengthy damage assessment prior to classification. No attempt is made in this EAL to assess the actual magnitude of the damage.

Threshold Value 1 - This EAL addresses an earthquake that exceeds the Operating Basis Earthquake level of .05 g and is beyond design basis limits. An earthquake of this magnitude may be sufficient to cause damage to safety related systems and functions. The Max Credible Earthquake for PBAPS is 0.12 g per UFSAR Section 1.6; therefore, this EAL is conservative and warrants an Alert classification.

Confirmed - As used in this EAL, a call to the National Earthquake Center is the primary confirmation source. Other confirmation includes reports from television or radio stations, or reports from university monitoring stations.

Threshold Value 2 - This EAL is based on FSAR design basis. Wind loads of this magnitude can cause damage to safety finctions. This EAL addresses events where a Plant Vital Structure has been struck with high winds, and thus damage may have occurred to safe shutdown systems.

Threshold Value 3 - Structural damage should be of sufficient force, that in the Emergency Director's judgment, the potential exists to affect the operation of systems and functions required for safe shutdown of the plant. This EAL specifies a Plant Vital Structure, which contain systems and functions required for safe shutdown of the plant Threshold Value 4 - The intent is to address such items as aircraft, train, barge or large motor vehicles (e.g. cranes, etc.). Automobiles, trucks and forklifts are also vehicles within the context of this EAL; however, the key is whether or not the vehicle can potentially affect a plant vital fumction, located within a designated Plant Vital Structure.

Threshold Value 5 - Missile impacts including rotating equipment or turbine failure causing casing penetration.

Peach Bottom Atomic Power Station Annex Exelon Nuclear Table PBAPS 3-2: EAL Technical Basis RECOGNITION CATEGORY HAZARDS AND OTHER CONDITIONS HA3 - Cont'd IBASIS.(Reec es)- C......

Threshold Value 6 - High River level > 116 feet is indication of the river being in flood. This level is capable of causing flooding that can affect Plant Vital Structures. General grade at the site of Units 2 &

3 has been established at a nominal 115 feet elevation in the area surrounding the Turbine Hall and other structures on the river side of the plant. Top of ground floor of the structures in this area is at 116 feet elevation. No attempt should be made to determine the magnitude of flooding. This is a long lead time event but this level is ground elevation of the reactor building and intake pump structure so classification as an Alert Event is appropriate. The evidence of flooding is sufficient for declaration.

Low River level < 92.5 feet is indication of a potential loss of Conowingo Pond and subsequent loss of the main condenser circulating water pumps if water level continues to drop.

Threshold Value 7 - Flooding in vital areas that affect operability of safety-related systems or components. The source of the flooding need not be known.

This event will be escalated to a higher emergency classification based upon damage consequences covered under other various EAL Sections.

The Emergency Director should consider how these Threshold Values may affect both units due to the affects of common or shared plant systems.

Threshold Value 1 - This EAL addresses a sensed earthquake. The magnitude of .Olg is the lowest detectable earthquake measured on PBAPS seismic instrumentation per procedure SO 67.7.A. An earthquake of this magnitude may be sufficient to cause minor damage to plant structures or equipment within the Protected Area. Damage is considered to be minor, as it would not affect physical or structural integrity. This event is not expected to affect the capabilities of plant safety functions. This event will be escalated to an Alert if the earthquake reaches an Operating Basis Earthquake (OBE).

Threshold Values 2 & 3 - A tornado touching down within the Protected Area or wind speeds > 75 mph within the Owner Controlled Area are of sufficient velocity to have the potential to cause damage to Plant Vital Structures. The value of 75 mph was selected to maintain consistency with plant value and to coincide with the Beaufort Scale for Hurricane wind speed winds of 73-136 mph. These criteria are indicative of unstable weather conditions and represent a potential degradation in the level of safety of the plant. Verification of a tomado will be by direct observation and reporting by station personnel.

Verification of wind speeds > 75 mph will be via meteorological data in the control room. This event will be escalated to an Alert if the tornado or high wind speeds strike a Plant Vital Structure.

Threshold Value 4 - This criterion is intended to address such items as plane, helicopter, train or other "vehicle" crashes that may potentially damage plant structures containing functions required for safe shutdown of the plant. Automobiles, trucks and forklifts are also vehicles within the context of this EAL; however, the key is whether or not the vehicle can potentially cause significant damage to plant structures. If the crash is confirmed to affect a plant vital function contained in a designated Plant Vital Structure, the event may be escalated to an Alert classification.

Threshold Value 5 - This criterion is intended to address main turbine rotating component failures of sufficient magnitude to cause observable damage to the turbine casing or to the seals of the turbine generator. Of major concern is the potential for leakage of combustible fluids (e.g., lubricating oils) and gases (e.g., hydrogen) to the plant environs. Actual fires and flammable gas build up are appropriately classified via other EALs. Turbine failure of sufficient magnitude to cause observable damage to the turbine casing or seals of the turbine generator raises the potential for leakage of combustible fluids and gases (Hydrogen cooling) to the Turbine Building. The damage should be readily observable and should not require equipment disassembly to locate.

May 2003 PBAPS 3-104 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex Exelon Nuclear Table PBAPS 3-2: EAL Technical Basis RECOGNITION CATEGORY HAZARDS AND OTHER CONDITIONS HU3 - Cont'd Threshold Value 6 - This criterion allows for the control room to determine that an event has occurred and take appropriate action based on personal assessment as opposed to verification (e.g., an earthquake is felt but does not register on any plant-specific instrumentation, etc.)

Threshold Value 7 - Cooling water is pumped from the normal heat sink (Conowingo Pond) via the pump structure. An alternate suction supply and discharge path (from the emergency heat sink -

which consists of an induced draft cooling tower with an integral storage reservoir) is available in the unlikely event of a Conowingo Dam failure.

High River level of greater than 112 feet: At this level open grating in the operating floor of the Circulating Water Pump Structure will allow water from the circulating water bays to rise into the structure during postulated external flooding conditions. Per the UFSAR, "The configuration of the circulating water system would likely trip at a flood elevation of about 113 feet Therefore, a river elevation of 11 feet was chosen as the elevation at which a flood-related shutdown is initiated." The use of a threshold of 112 feet for the Unusual Event would represent a condition above T. S., but prior to the postulated loss of circulating water.

Low River level of less than 98.5 feet: This is the plant low water design level and consistent with T.S.

3.7.2 (Minimum Water Level in Pump Bay). Per the UFSAR, with the river level is 104 feet when an uncontrolled release of about 350,000 cfs is passed through the Conowingo Dam and there is no in flow into pond, it will require about 1-1/2 hours to drop level to 98.5 feet This event will be escalated to an Alert classification based continuation of the river situation.

Cout'd .. ~~~~~~~~~~~~~~~~~~~~~~~~..... .....

Fire - combustion characterized by the generation of heat and smoke. Sources of smoke such as overheated electrical equipment and slipping drive belts, for example, do not constitute fires.

Observation of a flame is preferred, but is NOT required if large quantities of smoke and heat are observed.

The primary concern of this EAL is the magnitude of the fire and the effects on Safe Shutdown Systems required for the present Operational Condition. A Safe Shutdown System is defined as any system required to maintain safe operation or to establish or maintain Cold Shutdown. A system being "inoperable" means that it is incapable of performing the design function. For example, the LPCI System is intended to maintain adequate core cooling by covering the core to at least 2/3 core height following a DBA LOCA. In order for the system to be unable to maintain its intended function, multiple loops would need to be disabled by the fire. In addition to indication of degraded system performance, potential inoperability may be determined by visual observation and other control room indications such as loss of indicating lights.

Safe Shutdown Analysis is consulted to determine systems required for the applicable mode.

Two examples of applying this methodology are as follows:

  • Diesel Generators and 4 KV Safeguard Buses: The fire disables multiple Diesel Generators or 4 KV Safeguard Buses so that the number of emergency power systems available would be lowered to below what would be required to mitigate an accident under the current operating conditions. For 100% power, this could be conservatively interpreted as at least two Diesel Generators or 4 KV Buses disabled.
  • RHR - LPCI Mode: The fire disables multiple loops of LPCI so that adequate core submergence could not be assured following a DBA LOCA. For 100% power, this could also be conservatively interpreted as at least two loops disabled.

The EAL includes the condition that the fire must make "TWO OR MORE" subsystems (as defined by Tec. Specs.) or "TWO OR MORE" systems inoperable. In those cases where it is believed that the fire may have caused damage to Safety Systems, then an Alert declaration is warranted, since the full extent of the damage may not be known. For Plant Vital Structure damage, classification is required under this EAL if the structure houses or otherwise supports Safety Systems required for the present Operational Condition.

Degraded system performance or observation of damage that could degrade system performance is used as the indicator that the safe shutdown system was actually affected or made inoperable. A report of damage should not be interpreted as mandating a lengthy damage assessment prior to classification. No attempt is made in this EAL to assess the actual magnitude of damage. The occurrence of the fire or explosion with reports of damage (e.g., deformation, scorching) is sufficient for declaration.

Verification - Determination is made that the fire alarm is not spurious.

Explosion - A rapid, violent, unconfined combustion, or a catastrophic failure of pressurized equipment, that potentially imparts significant energy to nearby structures or equipment.

The purpose of this IC is to address the magnitude and extent of fires that may be potentially significant precursors to damage to safety systems. This excludes such items as fires within administration buildings, wastebasket fires, and other small fires of no safety consequence. This IC applies to buildings and areas contiguous to plant vital areas or other significant buildings or areas. The intent of this IC is not to include buildings (e.g., warehouses) or areas that are not contiguous or immediately adjacent to plant vital areas.

MS XS Verification of the alarm in this context means those actions taken in the control room to determine that the control room alarm is not spurious.

This EAL addresses fires in Plant Vital Structures that house safety systems. These fires may be precursors to damage to safety systems contained in these structures. There are no areas/buildings contiguous to Plant Vital Structures, which could affect a safety system in one of the listed Plant Vital Structures except for those already on the list Therefore, no additional areas/buildings are considered for this EAL.

Verification that a fire exists is by operator actions to confirm that fire alarms received in the Control Room are not spurious or by any verbal notification by plant personnel. Fifteen minutes has been established to allow plant staff to respond and control small fires or to verify that no fire exists.

This event will be escalated to an Alert if the fire damages redundant trains of plant safety systems required for the current operating condition.

Gases within the site boundary that are above life-threatening or flammable concentrations, and have exceeded those concentrations within a Plant Vital Structure (as defined under Table H-i), should be declared as an Alert.

This IC is based on gases that have entered a plant structure affecting the safe operation of the plant.

This IC applies to buildings and areas contiguous to plant Vital Areas or other significant buildings or areas. The intent of this IC is not to include buildings (e.g., warehouses) or other areas that are not contiguous or immediately adjacent to Plant Vital Areas. It is appropriate that increased monitoring be done to ascertain whether consequential damage has occurred.

Concentrations above life-threatening or flammable concentrations that result from planned maintenance or repair activities on-site, where planned contingency measures are identified to monitor and control gas(es), do not require classification.

Threshold #1: Toxic gas concentration results in an atmosphere that is immediately harmful to unprotected personnel, and would preclude access to any such affected area However, access into the affected area does not have to be required for classification purposes.

ALL Gases within the site boundary that are above life-threatening or flammable concentrations, and have not exceeded those concentrations within a Plant Vital Structure (as defined under Table H-I in IC HAI), should be declared as an Unusual Event.

A toxic/flammable gas is considered to be any substance that is dangerous to life or limb by reason of inhalation or skin contact. It should not be construed to include confined spaces that must be ventilated prior to entry.

This IC is based on releases in concentrations within the site boundary that will affect the health of plant personnel or the safe operation of the plant with the plant being within the evacuation area of an offsite event (e.g., tanker truck accident releasing toxic gases, etc.). The evacuation area is determined from the DOT Evacuation Tables for Selected Hazardous Materials in the DOT Emergency Response Guide for Hazardous Materials.

Concentrations above life-threatening or flammable concentrations that result from planned maintenance or repair activities on-site, where planned contingency measures are identified to monitor and control gas(es), do not require classification.

Multi-unit stations with shared safety functions should further consider how this IC may affect more than one unit and how this may be a factor in escalating the emergency class.

This EAL allows the Emergency Director to declare an Alert upon the determination that the level of safety of the plant has substantially degraded but is not explicitly addressed by other EALs. This includes a deternination by Shift Management that the TSC and OSC should be activated and command and control functions should be transferred for the event to be effectively mitigated. Transfer of command and control functions is used as an initiator since an event significant to warrant transfer is a substantial reduction in the level of safety of the plant. Other examples are:

.....a : ; .. .. .0 0...0 This EAL is intended to address unanticipated conditions not addressed explicitly elsewhere but warrant declaration of an emergency because conditions exist which are believed by the Emergency Director to fall under the Unusual Event emergency class.

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

From a broad perspective, one area that may warrant Emergency Director judgment is related to likely or actual breakdown of site-specific event mitigating actions. Examples to consider include inadequate emergency response procedures, transient response either unexpected or not understood, failure or unavailability of emergency systems during an accident in excess of that assumed in accident analysis, or insufficient availability of equipment and/or support.

It is also intended that the Emergency Director's judgment not be limited by any list of events as defined here or as augmented by the site. This list is provided solely as examples for consideration and it is recognized that actual events may not always follow a pre-conceived description May 2003 PBAPS 3-116 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex Exelon Nuclear Section 4: Emergency Measures 4.1 Notification of the Emergency Organization Notifications for the Peach Bottom Atomic Power Station are made to the following additional State and local agencies in accordance with Section E.3 of the Exelon Nuclear Standardized Radiological Emergency Plan:

  • Cecil County Emergency Management & Civil Defense Agency
  • Chester County Department of Emergency Services
  • Harford County Division of Emergency Operations
  • York County Emergency Services Notification of PEMA and the risk counties will be directed by the Emergency Director within 15 minutes of initial event classification, reclassification, or a change in a protective action recommendation (PAR) due to plant conditions or meteorological changes per Section E.3 of the Exelon Nuclear Standardized Radiological Emergency Plan. In addition, once the EOF is activated, the Corporate Emergency Director will contact the Senior Pennsylvania State Official as designated by PEMA following the decision to recommend a protective action for the general public.

Upon notification of an emergency at Peach Bottom Atomic Power Station, the Pennsylvania Bureau of Radiation Protection (BRP) and Maryland Department of the Environment (MDE) will contact the appropriate station to verify that an emergency exists and to obtain technical information, and then makes recommendations to PEMA and MEMA respectively, regarding protective actions for the public. The BRP/ MDE Support Plan For Fixed Nuclear Facility Incidents utilizes the Protective Action Guidelines in the U.S. Environmental Protection Agency (EPA) 400-R-92-001, "Manual of Protective Action Guides and Protective Actions for Nuclear Incidents".

Exelon Nuclear will provide follow-up information to the BRP/MDE or other off-site authorities. The follow-up information will keep these authorities apprised of existing or potential radiological releases, meteorological conditions, projected doses and contamination levels, licensee actions, recommend protective actions and other information pertinent to the authorities responsibilities. The information may be provided over open communication paths or in person to BRP/MDE personnel.

May 2003 PBAPS 4-1 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex Exelon Nuclear 4.2 Assessment Actions The effluent radiation monitoring system provides indications of gross releases of gaseous and liquid radioactivity. By applying calibration factors, meteorological data, or river flow, the gross indications are used to calculate approximate release rates in i+/-Ci/sec and dose rates at specific distances along the release pathways. Particulate and iodine analysis depends on collecting installed filter papers and charcoal cartridges for analysis in the counting room.

Similar calculation procedures are applied to approximate release rates and dose rates due to iodine.

Detectors are strategically located throughout the plant. These detectors indicate and alarm locally and in the Control Room. They serve the purpose of indicating current dose rates in those areas and are used for local evacuation action levels and re-entry operations.

Certain plant operating systems contain radiation monitors. These systems are described in the PBAPS UFSAR.

Portable monitoring instruments and sampling equipment consist of such items that are utilized and maintained on-site by the Chemistry and Health Physics sections for normal day-to-day plant operations and are thus available for emergency operations.

4.2.1 Assessment Without Instrumentation Should the effluent radiation monitors be off-scale or otherwise inoperable, assessment of releases and off-site exposure would be made using the containment monitor readings, point of release grab samples, and pathway samples.

a. Containment Monitors -- These Containment Radiation Monitor Dose Rate Curves have been developed to indicate the quantity of airborne activity released from the fuel and from the primary coolant system to the containment in a design basis accident (DBA), like a loss of coolant accident (LOCA). This activity is theoretically available for leakage or release to the environment.

The theoretical curves of gross gamma dose rate vs. time for seven potential source terms are provided in Figures PBAPS 4-la&b.

These figures correlate the containment high range radiation monitor readings (R/hr) to the percent of fuel inventory released to the containment atmosphere as a function of time after plant shutdown (Figure PBAPS 4-la&b). The percentage of fuel inventory released can be converted to radioactivity (Curies) available for release by multiplying by a noble gas isotopic spectrum determined by the Post-Accident Sampling System (PASS). For periods when the PASS isotopic spectrum is not available, and for other than noble gas isotopes, a default core activity spectrum can be used. Isotopic releases distributions can be entered into Dose Assessment and Protective Action Recommendation (DAPAR) dose model to project doses.

The set points on this monitor could be used to indicate to the operator that the Emergency Action Levels (EALs) were reached under the Fission Product Barrier loss matrix provided in Section 3.

b. Grab Samples - Particulate, iodine, and noble gas grab samples can be obtained from the effluent monitors located at the release points. Analyses of the samples are performed in the counting room facilities to determine isotopic breakdown release rates. The data can be entered into the DAPAR dose model to determine off-site doses.
c. Point of Release Samples - Point of release samples (i.e., top of stacks or at vent) are obtained using available equipment and procedures. Analyses of the samples are performed at the counting room facilities, and release rates can be determined. Release rates are then used to calculate off-site dose projections.
d. Pathway Samples -- Off-site samples in the plume pathway are obtained by using available equipment and procedures. Analysis data can be back-calculated to the point of release, and projected dose rates at locations of interest can be evaluated.

4.3 Protective Actions for the Offsite Public For incidents at PBAPS, PEMA coordinates with MEMA and contacts York, Lancaster and Chester County Emergency Management Agencies to assure that local plans have been implemented. MEMA likewise contacts Cecil and Harford Counties in the event of emergency at PBAPS to assure that all plans have been implemented. County and local governments have primary responsibilities for implementing protective measures for the public following a nuclear incident.

The BRP and MDE serve as lead State agency, in Pennsylvania and Maryland respectively, for technical assistance to other state agencies, county, and local governments regarding radiological health and accident assessment. In the absence of communications with the state, recommendations for protective actions shall be made directly to county emergency operations centers from the station.

4.3.1 Alert and Notification System (ANS) Sirens Annex E of the Commonwealth of Pennsylvania Emergency Operations Plan and Annex Q of the Maryland Radiological Emergency Plan address notification to the general public and others regarding protective actions. An Alert Notification System, which is intended for use by the counties, in conjunction with the Emergency Alert System (EAS) to provide notification to the general public, has been installed.

Alerting of the EPZ population is provided by a siren system that was installed and is maintained by Exelon Nuclear. The system consists of high-powered rotating electro-mechanical sirens mounted on Class 1 utility poles throughout the Plume Exposure Pathway (10-Mile EPZ). Personnel at the risk county communication centers operate the sirens. The Pennsylvania Emergency Management Agency (PEMA), in conjunction with Maryland and the risk counties, coordinates the activation of the siren system for Peach Bottom Atomic Power Station.

The siren system meets or exceeds the acoustic coverage requirements outlined in NUREG-0654/FEMA-REP-1 and FEMA-REP-10. The location of each siren site was determined by a computer-based sound propagation model.

May 2003 PBAPS 4-3 EP-AA-1007 (Revision 7)

Peach Bottom Atomic Power Station Annex FYelnn Nuelpar L The sirens are controlled by digitally encoded radio signals transmitted by a transceiver at the station. Each risk county has control of the sirens that are physically located in that county. The sirens can be activated on an individual, municipal, county, or EPZ-wide basis. A controller located at the station serves as a backup to the county controllers. After the system is activated, each siren reports the result of its activation back to the respective county controller and the controller at the station.

The siren system is tested regularly to ensure its operability.

Annex E (to the PA Emergency Operations Plan) and Annex Q (to the Maryland REP) delineate risk counties as responsible to:

  • Develop a system for rapid notification (in priority order) of county and local government heads, key staff, emergency forces, volunteer organizations, schools, hospitals, nursing homes, business, and industry;
  • Ensure that the alert and notification system is operable on an around-the-clock basis;
  • Prepare and disseminate public information material on protective actions to provide clear instructions to the population at risk;
  • Prepare and maintain material current for dissemination through the EAS; and
  • Include provisions in the alert plan for notification of transients.

PEMA/MEMA will notify other states within the Ingestion Pathway EPZ should such action be necessary.

Annex E (to the PA Emergency Operations Plan) and Annex Q (to the Maryland REP) also call for each risk county to promptly activate their alert notification system, when appropriate. EAS radio stations will be activated and instructed as to which prepared message to use. Detailed messages with specific instructions to the public will be provided to the EAS stations by state and county public information officers on a timely basis. Various state agencies will assist the counties in assuring notifications of transients.

4.3.2 Evacuation Time Estimates The evacuation time estimates (ETE) were developed in coordination with the Commonwealth of Pennsylvania and State of Maryland to assess the relative feasibility of an evacuation of the 10-Mile EPZ for the Peach Bottom Atomic Power Station. The evacuation times are based on a detailed consideration of the EPZ roadway network and population distribution. The ETE Study, maintained separately by Emergency Preparedness, presents representative evacuation times for daytime and nighttime scenarios under various weather conditions for the evacuation of various areas around the Peach Bottom Atomic Power Station, once a decision has been made to evacuate.

4.3.3 Potassium Iodide (KI)

The Department of Health, Commonwealth of Pennsylvania, is responsible for providing advice to PEMA on the planning for the use, stockpiling and distribution of Potassium Iodide (I) or other thyroid blocking agents and such other radiological health materials as may be required for the protection of the general public. Their decision shall also be based on U.S. FDA guidance.

The use of KI in the State of Maryland will be in accordance with state health laws and under the direction of State and County Medical Officials.

Based on agreement with the Maryland Department of the Environment (MDE), the PBAPS will recommend to Maryland government officials that the general public be notified to take KI at a General Emergency classification in those sectors were an evacuation has been recommended. This notification will be approved by the Emergency Director in Command and Control of PAR decision-making and off-site notifications, and performed as part of the State / local notifications described under Sections II.B.4 and II.E.3 of the Exelon Nuclear Standardized Radiological Emergency Plan.

4.3.4 Public Information a Publications Public information on protective actions is prepared and disseminated annually to provide clear instructions to the population-at-risk. Exelon Nuclear assists PEMA/MEMA and risk counties in the preparation and distribution of their respective public information..

Pamphlets outlining public education response actions are readily available for transients in the 10-Mile EPZ. In addition, emergency information is provided to the operators of other recreational areas in the 10-Mile EPZ.

These public information publications (including telephone book emergency information, etc.) instruct the public to go indoor and turn on their radios when they hear the ANS sirens operating. These publications identify the local radio stations to which the public should tune in for information related to the emergency. Additional materials (e.g., such as rumor control numbers, evacuation routes, information on inadvertent siren soundings, etc.) may also be included in these publications based on agreements with responsible State and risk county agencies.

b. News Media Education Information kits are available to news media personnel. These kits include information on a variety of nuclear power plant related subjects.

4.3.5 Protective Action Recommendations (PARs) for the General Public Figure PBAPS 4-2, "PAR Flowchart", illustrates affected downwind sectors based on wind direction, using the generic plant-based event logic as outlined in Figure J-1 of the Exelon Nuclear Standardized Radiological Emergency Plan.

4.4 Protective Actions for Onsite Personnel 4.4.1 Plant Evacuation Exelon Nuclear personnel and contractors filling emergency response organization positions are considered essential personnel. As such, they will report to their emergency response locations. They will not evacuate unless specifically directed by the Emergency Director. All other personnel are considered non-essential.

In-plant evacuation is initiated primarily by area radiation monitor alarms and continuous air monitor alarms, but is also applicable for fire alarms, explosions, toxic material conditions, as well as radiation, contamination, and airborne radioactivity surveys which indicate conditions above applicable limits. Notification for personnel to proceed with in-plant evacuation will be via a local alarm or an announcement on the plant PA system. The affected area and evacuation assembly areas (if appropriate) will be announced. The immediate response by individuals in the vicinity of such an alarm or announcement is evacuation to an unaffected area or designed assembly area.

In the absence of readily available radiological survey information or other logical assessment of conditions, evacuation will be, at least, to a point where other area radiation monitors, continuous air monitors, or observation of local conditions show that the area is not affected.

Assigned plant personnel report to the scene to evaluate conditions, to provide information to the Control Room, and to perform other emergency functions such as personnel accountability, decontamination, medical assistance, and control of the hazard.

Notification of a Site Evacuation is accomplished by activating the Evacuation Alarm System followed by an announcement over the plant PA system. The evacuation assembly area(s) are announced. Evacuation assembly areas are illustrated in Figure PBAPS 4-3. Non-essential personnel will exit via the security exit points and will proceed to the parking lot for transportation. Evacuees are expected to use their personal vehicles in evacuating to the designated evacuation assembly area(s).

Designated evacuation assembly areas are located out side the protected area. Plant access roads are maintained clear during the winter months, travel on these roads is expected to be possible at all times.

Plant visitors who have not completed the required training program are escorted at all times. This ensures proper response under emergency conditions. Visitors at the station shall follow the lead of their escorts to the assembly areas.

4.4.2 Personnel Accountability The Security personnel shall follow security procedures for personnel accountability.

For evacuations, information from evacuees is an important means of accounting for plant personnel. For Site Evacuations, non-essential personnel and those ERO members whose facility is located outside the Protected Area are accounted for at the security exit point. Emergency response personnel responding to the OSC within the Protected Area are accounted for by badging into designated card readers.

Necessary personnel and vehicle decontamination efforts are initiated at the evacuation assembly area using in-plant equipment or emergency kit supplies. Priority for decontamination shall be given to personnel found to have the highest levels of contamination. Any personnel suspected, or known, to have ingested or inhaled radioactive material shall be given a whole body count, as soon as conditions permit, to assess their internal exposure.

4.5 Severe Accident Management Accident management consists of those actions taken during the course of an accident, by the Emergency Response Organization (ERO), specifically: plant operations, technical support, and plant management staff in order to:

  • Prevent the accident from progressing to core damage;
  • Terminate core damage once it begins;
  • Maintain the capability of the containment as long as possible; and
  • Minimize on-site and off-site releases and their effects.

The later three actions constitute a subset of accident management, referred to as Severe Accident Management (SAM) or severe accident mitigation. The Severe Accident Management Plan (SAMP) procedures provide sound technical strategies for maximizing the effectiveness of equipment and personnel in preventing, mitigating and terminating severe accidents.

Implementation of SAMP procedures is a collaborative effort between the Shift Manager and the Station Emergency Director in the TSC (once activated). The Station Emergency Director maintains ultimate responsibility for direction of mitigating strategies. Designated TSC Technical and Operations Support personnel are also trained to assist with decision-making by evaluating plant conditions using the SAM Technical Support Guidelines (TSG).

5.2 Assessment Resources 5.2.1 Geophysical Monitors

a. Onsite Meteorological Monitoring Program The Onsite Meteorological Monitoring Program is covered in the contractor specification and vendor procedures of the meteorological monitoring contractor. These data are used to generate wind roses and to provide estimates of airborne concentrations of gaseous effluents. Meteorological data is provided to the station Control Room from Meteorological Towers. Data include wind speed, wind direction, and temperature. Meteorological monitoring is described in the PBAPS UFSAR.
b. Seismic Monitoring Seismic instrumentation includes time-history strong motion pressure triaxial seismic monitor accelerographs located in secondary containment. Peak recording accelerographs, and seismic switches are discussed in the PBAPS UFSAR.

5.2.2 Radiation Monitoring Equipment For radiological assessments, instrumentation includes area radiation monitors (ARMs), ventilation effluent radiation monitors, liquid effluent radiation monitors, stack effluent monitors, primary containment radiation monitors and miscellaneous process radiation monitors (Refer to PBAPS UFSAR Section 7 for additional information). Data from these sources would be augmented by plant and field surveys for radiation and airborne levels.

a Post-Accident Sampling Capability The Post Accident Sampling System (PASS) is designed to obtain representative liquid and gas samples from within the primary containment for radiological analysis in the event of a loss-of-coolant accident. PASS gaseous samples are analyzed for noble gas only.

Post-accident monitoring equipment includes noble gas effluent monitors and iodine and particulate filters on the Main Stack for Peach Bottom. The equipment is located to permit access for retrieval of samples under accident conditions. High range radiation monitors are provided in the primary containment. This equipment is more fully described in the PBAPS UFSAR.

b. Radiological Effluent Gaseous Monitoring PBAPS has five points of release of radioactive material to the atmosphere.

These are the Main Off-Gas Stack, Units 2 and 3 Roof Vents and Torus Hardened Vents. Sample systems are installed for three pathways, Main Stack and two Roof Vents. The sample systems consist of isokinetic sample lines containing particulate/iodine filters, and separate sample lines to shielded gas chambers. Detector outputs associated with the gas chambers are recorded in the Control Room. Roof Vent and Main Stack flow rates are also recorded in the Control Room.

The roof vent radiation monitoring system continuously monitors the noble gas being discharged from the Peach Bottom Unit 2 and Unit 3 roof vents. Each unit has two independent monitoring stations. The monitoring stations use scintillation detectors, which read out digitally in the Control Room.

A representative sample of the Torus Hardened Vent (THV) effluent can be obtained by utilizing the Post Accident Sampling System (PASS). The PASS is capable of sampling containment atmosphere prior to and during the use of the Torus Hardened Vent. The THV radiation monitoring system consists of GM type radiation detectors. One monitor is externally mounted to the vent.

Both monitors readout in cpm, and are displayed on a digital monitor in the Control Room.

The refuel floor exhaust is combined with other building exhaust streams and is monitored by the Ventilation Stack Radiation Monitoring system for each unit. All alarm functions and readouts are in the Main Control Room. There are also several Area Radiation Monitors on the refuel floors that provide both local and Main Control Room alarm and readout.

Peach Bottoms' gas chamber detector recorder readouts are converted to uCi/sec of noble gas using calibration data and effluent flow rates for each point of release. The uCi/sec Iodine and particulates are determined from the filter and charcoal cartridge samples. The dose projection system then relates meteorological and radiological data to project dose rates along the plume pathway for selected distances. Appropriate atmospheric distribution coefficients are selected for distances of interest from the point of release.

Dose rates at these distances are calculated using this data.

c. Radiological Effluent Liquid Monitoring Liquid releases are made on a batch basis from waste sample tanks. The contents of these tanks are circulated prior to sampling and analysis and release in the discharge canal. Release forms are prepared to authorize releases to the discharge canal. Potentially, plant system leaks could cause discharge to the canal directly. Radiation monitors are located on certain process water systems that indicate abnormal radioactivity levels. A point of release sampling system is located at the end of the discharge canal.

d. Laboratory Facilities Chemical laboratories are in the Plant Entrance and Radiochemistry Laboratory (PEARL) at PBAPS. A radiochemistry section is provided. The laboratories are adjacent to the counting room for convenience in transporting prepared samples for counting.

5.2.3 Data Acquisition Methods

a. Plant Monitoring System (PMS)

The PBAPS Main Control Room (MCR) and Technical Support Center (TSC) use an emergency facility data system to aid in assessing plant response and status during emergencies. PMS is a computer-based real-time data acquisition and display system, which gathers and records, selected plant parameters for display.

The system displays are designed to aid the Control Room operator in the performance of emergency response procedures. These displays provide information pertinent to reactor core cooling, reactor coolant system integrity, reactivity control, containment integrity, and power system status. These displays are also available to personnel in the TSC.

PMS also provides concise displays of parameters selected for post-accident monitoring. These displays are designed to aid TSC personnel in assessing plant conditions and in assisting Main Control Room personnel in recovering from abnormal or accident conditions and in mitigating their consequences.

The displays include parameter versus time and parameter versus parameter trending.

PMS utilizes high-speed data recording, long-term data storage and a transient analysis program package to aid the Technical Support Center staff in reconstructing the accident sequence as well as tracking the plant steady state and dynamic behavior prior to and through the course of an event. PMS displays are available in the Main Control Room and TSC, and EOF through EPDS interactive color graphic display consoles. Hardcopy output devices are available at each location. Provisions have been made to share data with State Liaisons located in the EOF.

b. Emergency Preparedness Data System (EPDS)
