Title:

Recognition & Classification of Emergency Conditions EN-EP-305 R008 Part I. Description of Proposed Change:

1.

Change 1 was screened out and will not be evaluated.

2.

In Attachment 7.1, under AA1 EAL #2, Table A2: Changed the values given for PRM-IRE-0627 and PRM-IRE-0647 from 5.38E-01 uCi/ml to 8.55E-02 uCi/ml, AND added PRM-IRE-6775, PRM-IRE-6776, PRM-IRE-6778, PRM-IRE1900, and PRM-IRE-0648, and their associated maximum operating range values. Relocated Table A2 from part b of the EAL to part a.

3.

In Attachment 7.2, under AA1 EAL #2, Table A2: Changed the values given for PRM-IRE-0627 and PRM-IRE-0647 from 5.38E-01 uCi/ml to 8.55E-02 uCi/ml, AND added PRM-IRE-6775, PRM-IRE-6776, PRM-IRE-6778, PRM-IRE1900, and PRM-IRE-0648, and their associated maximum operating range values. Relocated Table A2 from part b of the EAL to part a.

4.

In Attachment 7.2, under AU1 EAL #2: Added the statement, Historical release permits indicate that the NOUE value of 2 times the radiation monitor setpoint established by the current permit may exceed the operating range of the monitor in some instances. For release permit monitors that have an associated WRGM (plant stack and Fuel Handling Building exhaust), the WRGM mid or high range uCi/cc channel may be used to determine whether or not the EAL value is exceeded. Other potentially affected monitors are listed in Table A2 with a corresponding value for the top of their digital indicating range. If the monitor is at or exceeds the top of its indicated range, then refer to AA1.

5.

Change 5 was screened out and will not be evaluated.

NOTE: A before and after view of changes 2-4 is provided on page 6 of this document.

Part II. Description and Review of Licensing Basis Affected by the Proposed Change:

An electronic search of the Emergency Plan, EAL document (EP-001-001 Recognition & Classification of Emergency Conditions), the On-Shift Staffing Analysis, the Evacuation Time Estimate, and the Alert and Notification System Design Report was performed using keywords emergency classification 48 hits, none relevant; emergency action level 13 hits, none relevant; effluent 34 hits, none relevant, radiation monitor 19 hits, none relevant, overrange, 0 hits and off-scale 1 hit, not relevant.

Additionally, a manual review of the entire Emergency Plan was performed. The search of potentially affected Emergency Plan sections specifically focused on Emergency Plan Section 4.1 Waterford 3 Classification, Emergency Plan Table 4-1 Summary of Initiating Conditions, Emergency Plan Section 7.4 Assessment Facilities and Equipment, and Emergency Plan Table 7-2 Process and Effluent Radiological Monitors/Samplers.

A historical review of EP-001-001 Recognition & Classification of Emergency Conditions was performed to the last NRC Approved revision which was Revision 29 with the migration to NEI 99-01 Rev 5 EALs. This approval was provided in a letter dated July 18, 2011, with the subject WATERFORD STEAM ELECTRIC STATION, UNIT 3 - APPROVAL OF CONVERSION OF THE EMERGENCY ACTION LEVEL SCHEME TO SCHEME BASED ON NUCLEAR ENERGY INSTITUTE (NEI) 99-01, REVISION 5 (TAC NO. ME4726) with ADAMS Accession No. ML111380558. Additional historical review was performed to Revision 28 in which the table containing the maximum operating limit of the effluent radiation monitors was added.

The Initiating Conditions listed in Table 4-1 of the Emergency Plan are not changed by this procedure revision. Because this activity is only changing EP-001-001 Recognition & Classification of Emergency Conditions, and not changing the Waterford 3 Emergency Plan, a historical review of the Emergency Plan was not performed.

The proposed changes do not change any Initiating Condition described in the Emergency Plan. The proposed changes do affect EAL entry criteria detailed in EP-001-001 Recognition & Classification of Emergency Conditions for selected Unusual Event and Alert EALs in cases where a monitor reading based on a multiple of the release permit monitor setpoint results in an off-scale high value.

The proposed changes do affect effluent radiation monitor operating range values contained in Emergency Plan Table 7-2 Process and Effluent Radiological Monitors/Samplers. Emergency Plan Table 7-2 references tables in sections 11 and 12 of the FSAR. A change to the Emergency Plan will need to be processed upon a revision to the FSAR to correct the maximum operating limit values of the effluent radiation monitors as detailed in the engineering report provided with CR-WF3-2020-6312. This change to the Emergency Plan will be tracked by WT-WTWF3-2018-00166 CA-00043.

Page 2 of 6 10CFR50.54(Q)(3) Evaluation Procedure/Document Number: EP-001-001 Revision: Revision 34 Equipment/Facility/Other: Waterford 3

Title:

Recognition & Classification of Emergency Conditions EN-EP-305 R008 Part Ill. Describe How the Proposed Change Complies with Relevant Emergency Preparedness Regulation(s) and Previous Commitment(s) Made to the NRC:

10 CFR 50.47(b)(4) - A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures Site Compliance - A standard emergency classification and action level scheme based on NEI 99-01 Revision 5 remains in effect with this change. The change addresses the potential for a missed or untimely classification when a radiological release permit radiation monitor may be over ranged by the occurrence of an off-normal event associated with the release.

NRC Commitments - A Waterford 3 Licensing System search was performed using the Implementing Procedure query with an additional field to search for EP-001-001. A second search was performed using the Emergency Plan Query (EMPL) with additional fields added to specifically search commitment text. A search of commitments was performed with the following criteria EP-001-001, emergency classification, emergency action level, and initiating condition.

The proposed changes do not affect any commitments made to the NRC.

Part IV. Description of Emergency Plan Planning Standards, Functions and Program Elements Affected by the Proposed Change:

10 CFR 50.47(b)(4) - Emergency Classification System A standard scheme of emergency classification and action levels is in use.

Sections IV.B and IV.C of Appendix E to 10 CFR 50 provide supporting requirements. Informing criteria appear in Section II.D of NUREG-0654 and the licensees emergency plan.

Page 3 of 6 10CFR50.54(Q)(3) Evaluation Procedure/Document Number: EP-001-001 Revision: Revision 34 Equipment/Facility/Other: Waterford 3

Title:

Recognition & Classification of Emergency Conditions EN-EP-305 R008 Part V. Description of Impact of the Proposed Change on the Effectiveness of Emergency Plan Functions:

An engineering analysis of the maximum operating ranges for WF3 effluent radiation monitors and their relationship to EALs for radiological effluents - documented in CR-WF3-2020-06312 and validated by EC-88621 - has determined that under certain conditions 7 radiation monitors may be over ranged when the Unusual Event multiple (2) and/or Alert multiple (200) is applied to the alarm setpoint established for a discharge permit.

Changes 2 and 3:

CR-WF3 2019-01975 and CR-WF3-2020-06312 identified a condition where the maximum operating range of effluent radiation monitors used for evaluation of EAL AA1 could in some cases be lower than 200 times the established alarm setpoint for a radioactivity discharge permit. Under certain circumstances, the maximum operating range may also be lower than the Unusual Event limit for the discharge permit of 2 times the alarm setpoint. This issue is addressed in change 4. Using the maximum operating range values provided in the engineering report associated with CR-WF3-2020-06312, Table A2 was revised in EAL AA1 in Attachment 7.1 and the AA1 basis in attachment 7.2 to correct the values for the effluent radiation monitors already contained in the table, and to include additional effluent radiation monitors identified in the CR and their associated maximum operating values. The Emergency Director will use the most limiting condition of either the value listed in Table A2 or a valid reading of >200 times the alarm setpoint of the current discharge permit in making an Alert classification as specified in EAL AA1.2. In addition, the table was relocated from EAL 2.b to 2.a for ease of use and reference.

Continuous release permits are processed by the Chemistry Department for the Plant Stack, Main Condenser Exhaust, Fuel Handling Building Exhaust, Circulating Water (downstream of Steam Generator Blowdown cooling), Dry Cooling Tower Sumps, and the Turbine Building Industrial Waste Sump effluent pathways. The Chemistry technicians are able to access and change the alarm setpoint values for these associated effluent radiation monitors as directed by established procedural guidance. The Chemistry Department also establishes and sets alarm setpoints in accordance with established procedures and batch-discharge permits for the Boron Management, Liquid Waste Management, and Gaseous Waste Management effluent pathways. These effluent radiation monitor alarm setpoints are available to the Emergency Director for evaluation of entry criteria for emergency classifications.

These changes are much like changes made in EP-001-001 Revision 28 and evaluated under 10CFR50.54(q) where a similar condition was identified. These changes correct information added in Revision 28 for current conditions and add additional clarifying information.

Change 4:

This change provides for the event where the Unusual Event multiple of 2 times the monitor alarm setpoint for EAL 2 of AU1 may result in a value beyond the maximum operating range of the monitor. Information is provided in the basis to describe this condition that is aligned with information provided in the basis for AA1.

The AU1 basis information directs the user to AA1. In a condition where a discharge is ongoing that exceeds the maximum range of the monitor and isolation of the release is not successful in 15 minutes, an Alert is the applicable classification.

(Continued Next Page)

Page 4 of 6 10CFR50.54(Q)(3) Evaluation Procedure/Document Number: EP-001-001 Revision: Revision 34 Equipment/Facility/Other: Waterford 3

Title:

Recognition & Classification of Emergency Conditions EN-EP-305 R008 EALs:

Changes 2-4 address the condition where the actual magnitude of a radiological release is unknown because an ongoing release has exceeded the setpoint established by a discharge permit, has not been isolated, has exceeded the maximum range of the monitor and the Unusual Event and/or Alert threshold for the release is also greater than the maximum range of the monitor. The actual magnitude of the release may be determined by grab sampling and analysis (AU1 EAL #3/AA1 EAL #3). A minimum of 34 minutes is required to analyze the sample without consideration for the time taken to take the sample, prepare it and begin the analysis, while indication of an off-normal condition is present because the applicable radiation monitor is at the top of its range. Because the top of the range monitor reading cannot discriminate between the Unusual Event multiple of 2 and the Alert multiple of 200 and presents an unknown condition, the Alert classification is applicable. Use of this top of monitor range EAL threshold in this circumstance ensures a timely classification of the event at the maximum classification level that could be exceeded where the actual conditions are unknown. Six of the seven affected radiation monitors are liquid monitors. There is no Site Area Emergency or General Emergency classification applicable to a liquid release. For the last monitor, gaseous waste management, a downstream monitor is provided on the plant stack that would provide indication of Site Area Emergency or General Emergency conditions under AS1 or AG1 EAL 1. Therefore, the Alert classification is appropriate for the condition. A Site Area Emergency or General Emergency classification is not warranted or appropriate. Note that the choice of either 200 times the high alarm setpoint for the release, or off-scale high (top of range), meets the intent of the radiological effluent initiating conditions/emergency action levels of providing classification thresholds for UNPLANNED and/or uncontrolled releases of radioactivity to the environment.

EMERGENCY PLAN:

These changes do not affect any process detailed in the Emergency Plan. This change does, however, establish lower maximum operating limit values than what is shown in Table 7-2 of the Emergency Plan. The effectiveness of the Emergency Plan is not reduced because these operating limits have been determined to be different for some of the monitors through an engineering evaluation. The Emergency Plan reflects the operating limits that are in the FSAR. These Emergency Plan operating limits are provided for information based on FSAR content. The Emergency Plan does not direct emergency response based on the specific values for the operating range limits of the monitors. The EALs in EP-001-001 are being revised to reflect information that is based on specific values for the operating range of selected effluent monitors and to correct information already present for two of the monitors. The Emergency Plan should be revised upon a revision to the FSAR to correct the upper range values of the affected effluent radiation monitors. WT-WTWF3-2018-00166 CA-00043 has been initiated to track the needed change to the Emergency Plan.

This change does not affect any information (other than FSAR-sourced information in Table 7-2) or process detailed in the Emergency Plan.

CONCLUSION:

The proposed changes ensure that the operating ranges of the effluent radiation monitors will not be exceeded without entering into an emergency classification when the threshold for EAL entry is greater than the top of that range. These changes correct an identified adverse condition and therefore the effectiveness of the Emergency Plan has not been degraded or lost, but restored since it provides the Emergency Director with additional clarifying information to ensure a classification is not overlooked or masked by an EAL threshold for a radiation monitor indication that is beyond the operating range of the monitor, presenting an unknown condition to the decision maker. In addition, the proposed changes do not result in a change to the underlying NEI 99-01 Revision 5 scheme for the site specific EALs.

The proposed changes to the EP-001-001 Recognition & Classification of Emergency Conditions continue to meet the planning standards outlined in 10CFR50.47(b)(4) Emergency Classification System. The effectiveness of the emergency plan is not reduced. These changes can be incorporated without prior NRC approval.

3.0 RESPONSIBILITIES 3.1 The Emergency Director (ED) is responsible for implementation of this procedure 3.2 The Emergency Director (ED) is responsible for declaration of the appropriate emergency classification whenever, in his judgment, the station status warrants such a declaration.

3.3 The Shift Manager shall assume the responsibility and authority of the Emergency Director (ED) until such time that he is properly relieved of this duty by the EOF Duty Emergency Director 3.4 If the Shift Manager cannot immediately assume the duty of Emergency Director, then the Control Room Supervisor (CRS) shall assume the duty of Emergency Director until properly relieved by the EOF Duty Emergency Director or Shift Manager.

3.5 When the EOF is activated and responsibilities are transferred, then the EOF Emergency Director is responsible for implementation of this procedure and declaration of the appropriate emergency classification whenever, in his judgment, the station status warrants such a declaration.

3.6 The assessment, classification, and declaration of an emergency condition is expected to be completed within 15 minutes after the availability of indications (i.e. plant instrumentation, plant alarms, computer displays, or incoming verbal reports) to plant operators that an EAL has been exceeded.

3.6.1 The 15-minute criterion is not to be construed as a grace period to restore plant conditions to avoid declaring the event.

3.6.2 The emergency declaration should be made promptly without waiting for the 15 minute period to elapse once the EAL is recognized as being exceeded.

3.6.3 For EALs that specify duration of the off-normal condition, such as fire lasting 15 minutes, loss of power for 15 minutes, etc.:

The Emergency Director shall make the declaration at the first available opportunity when the time has elapsed (not after an additional 15 minutes)

The declaration should be made before the EAL is met (time duration has elapsed) when the Emergency Director has information that the off-normal condition will not be corrected within the specified time duration.

4.0 INITIATING CONDITIONS 4.1 An off-normal event has occurred, or is in progress.

NOTE This instruction does not replace any plant operating procedure. Ensure that any immediate actions (for example, use of Emergency Procedures) are taken for the proper operation of the plant. During an emergency condition, continue to use the appropriate plant procedures in parallel with this instruction.

4.2 An action step in a plant procedure refers to this instruction for classification of the indicated plant conditions.

Emergency Plan Implementing Instruction Recognition and Classification of Emergency Conditions EP-001-001 Revision 034 4

5.0 PROCEDURE 5.1 Definitions 5.1.1 Emergency Class - One of a minimum set of names or titles, established by the Nuclear Regulatory Commission (NRC), for grouping off-normal nuclear power plant conditions according to (1) their relative radiological seriousness, and (2) the time-sensitive onsite and offsite radiological emergency preparedness actions necessary to respond to such conditions. The existing radiological emergency classes, in ascending order of seriousness, are called: Notification of Unusual Event (Unusual Event),

Alert, Site Area Emergency, and General Emergency.

5.1.2 Initiating Condition (IC) - One of a predetermined subset of nuclear power plant conditions where either the potential exists for a radiological emergency, or such an emergency has occurred.

5.1.3 Emergency Action Level (EAL) - A pre-determined, site-specific, observable threshold for a plant Initiating Condition that places the plant in a given emergency class. An EAL can be: an instrument reading; an equipment status indicator; a measurable parameter (onsite or offsite); a discrete, observable event; results of analyses; entry into specific emergency operating procedures; or another phenomenon which, if it occurs, indicates entry into a particular emergency class.

5.2 Classification 5.2.1 Verify the off-normal event to ensure that the event is real.

5.2.2 Match the off-normal event with one of the following six emergency categories:

5.2.2.1 Abnormal Radiation Levels/Radiological Effluents TAB A 5.2.2.2 Cold Shutdown/Refueling System Malfunction TAB C 5.2.2.3 ISFSI Malfunction TAB E 5.2.2.4 Fission Product Barrier Degradation TAB F 5.2.2.5 Hazards and Other Conditions Affecting Plant Safety TAB H 5.2.2.6 System Malfunction TAB S 5.2.3 Refer to Attachment 7.1, Emergency Categories, under the category TAB selected in step 5.2.2 above, match the off-normal condition with the appropriate IC to determine the emergency classification.

5.2.4 If an event or condition existed which met or exceeded an IC but no emergency was declared and the basis for the emergency classification no longer exists at the time of the discovery (rapidly concluded event, missed classification or misclassified event), then do not classify the emergency or make offsite notifications.

5.2.4.1 Notify the NRC within one hour of the discovery of the undeclared or misclassified event in accordance with UNT-006-010.

Emergency Plan Implementing Instruction Recognition and Classification of Emergency Conditions EP-001-001 Revision 034 5

NOTE The effects of combinations of initiating conditions that individually constitute a lower classification may be considered as a possibly higher emergency classification.

5.2.5 Declare the highest emergency classification for which an IC has been met or exceeded.

5.2.6 Perform the emergency actions in accordance with the appropriate Emergency Plan Implementing Instruction, one of which is provided for each classification, as follows:

5.2.6.1 Unusual Event - EP-001-010 5.2.6.2 Alert - EP-001-020 5.2.6.3 Site Area Emergency - EP-001-030 5.2.6.4 General Emergency - EP-001-040 5.2.7 Assessment actions shall be continued, and if necessary, the emergency classification escalated (or downgraded) as more definitive information becomes available or if the plant conditions change.

6.0 FINAL CONDITIONS 6.1 The plant conditions which activated this instruction have been declassified to non-emergency status.

This is not an operating mode designation by Technical Specifications.

This basis document serves two basic functions:

It provides background and explanatory information based on NEI 99-01 to present a basis for the origination of the Waterford 3 EALs for reviewers and users.

The second function this basis document may provide is an aid to decision makers when making a determination to classify an emergency event. It is intended that decision makers have all the information in Attachment 7.1 of this procedure that they need to make a sound classification decision.

Information that may be useful to a decision maker in classifying emergency events is also contained in the Basis section for each IC in the Basis Document.

The expectation is that emergency classifications are to be made as soon as conditions are present and recognizable for the classification, but within 15 minutes or less in all cases of conditions present. A decision makers use of this Basis Document for assistance is not intended to delay the classification.

DEFINITIONS EP-001-001 Revision 034 30.2 (6 of 135)

The following definitions are taken from NEI 99-01 and the Waterford 3 Emergency Plan and applicable to the Waterford 3 emergency classification system:

AFFECTING SAFE SHUTDOWN: Event in progress has adversely affected functions that are necessary to bring the plant to and maintain it in the applicable HOT or COLD SHUTDOWN condition. Plant condition applicability is determined by Technical Specification LCOs in effect.

Example 1: Event causes damage that results in entry into an LCO that requires the plant to be placed in HOT SHUTDOWN. HOT SHUTDOWN is achievable, but COLD SHUTDOWN is not. This event is not AFFECTING SAFE SHUTDOWN.

Example 2: Event causes damage that results in entry into an LCO that requires the plant to be placed in COLD SHUTDOWN. HOT SHUTDOWN is achievable, but COLD SHUTDOWN is not. This event is AFFECTING SAFE SHUTDOWN.

BOMB: Refers to an explosive device suspected of having sufficient force to damage plant systems or structures.

CIVIL DISTURBANCE: A group of persons violently protesting station operations or activities at the site.

CONFINEMENT BOUNDARY: The barrier(s) between areas containing radioactive substances and the environment.

CONTAINMENT CLOSURE: The site specific procedurally defined actions taken to secure containment and its associated structures, systems, and components as a functional barrier to fission product release under existing plant conditions. Reference OP-901-131, Shutdown Cooling Malfunction, Attachment 7.1.

EXCLUSION AREA BOUNDARY (EAB): For Waterford 3 EALs, the Emergency Plan Exclusion Area Boundary is the site boundary. The term Exclusion Area Boundary or EAB" is used throughout the Waterford 3 EALs as the site boundary. The Emergency Plan defines the Exclusion Area Boundary (EAB) as The border of the EXCLUSION AREA or an area corresponding to a distance of 914 meters from the Waterford 3 reactor.

EXPLOSION: A rapid, violent, unconfined combustion, or catastrophic failure of pressurized/energized equipment that imparts energy of sufficient force to potentially damage permanent structures, systems, or components.

EXTORTION: An attempt to cause an action at the station by threat of force.

DEFINITIONS EP-001-001 Revision 034 31.2 (7 of 135)

FAULTED: in a steam generator, the existence of secondary side leakage that results in an uncontrolled drop in steam generator pressure or the steam generator being completely depressurized.

FIRE: Combustion characterized by heat and light. Sources of smoke such as slipping drive belts or overheated electrical equipment do not constitute FIREs.

The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

This IC addresses a potential reduction in the level of safety of the plant as indicated by a radiological release that exceeds regulatory commitments for an extended period of time.

ABNORMAL RADIATION LEVELS/RADIOLOGICAL EFFLUENTS EP-001-001 Revision 034 37.2 (13 of 135)

AU1 Waterford 3 incorporates features intended to control the release of radioactive effluents to the environment. Further, there are administrative controls established to prevent unintentional releases, or control and monitor intentional releases. The occurrence of extended, uncontrolled radioactive releases to the environment is indicative of degradation in these features and/or controls.

The ODCM multiples are specified in AU1 and AA1 only to distinguish between non-emergency conditions, and from each other. While these multiples obviously correspond to an offsite dose or dose rate, the emphasis in classifying these events is the degradation in the level of safety of the plant, NOT the magnitude of the associated dose or dose rate.

Releases should not be prorated or averaged over 60 minutes. For example, a release exceeding 4 times ODCM limits for 30 minutes does not meet the threshold for this IC.

This Initiating Condition includes any release for which a radioactivity release permit was not prepared, or a release that exceeds the conditions (e.g.,

minimum dilution flow, maximum discharge flow, alarm setpoints, etc.) on the applicable permit.

EAL #1 CAUTION The Emergency Director shall make the declaration no later than 60 minutes (EAL time limit) after an initial VALID reading on any of the applicable radiation monitors.

This EAL addresses radioactivity releases, that for whatever reason, cause effluent radiation monitor readings to exceed the threshold identified in the EAL.

This EAL is intended for sites that have established effluent monitoring on non-routine release pathways for which a release permit would not normally be prepared.

The values used on the Dry Cooling Tower and Turbine Building sump discharge are based on the release pathway being aligned to the Storm Water System or Discharge Canal vice the circulating water system and are not applicable if the pathway is aligned to the circulating water system. Grab sample analysis of the circulation water discharge, IAW EAL #3, would be necessary to determine the appropriate action.

This value may be associated with a planned batch release, or a continuous release path.

Continuous release permits are processed and retained by Chemistry for the plant stack, main condenser exhaust, Fuel Handling Building exhaust, dry cooling tower sumps and the Turbine Building industrial waste sump. The setpoints for these continuous release permits are the RM-11 high alarm setpoint for the monitor. The Chemistry shift technician can access these release permits (and setpoint values) as needed.

Historical release permits indicate that the NOUE value of 2 times the radiation monitor setpoint established by the current permit may exceed the operating range of the monitor in some instances. For release permit monitors that have an associated WRGM (plant stack and Fuel Handling Building exhaust), the WRGM mid or high range uCi/cc channel may be used to determine whether or not the EAL value is exceeded. Other potentially affected monitors are listed in Table A2 with a corresponding value for the top of their digital indicating range. If the monitor is at or exceeds the top of its indicated range, then refer to AA1.

ABNORMAL RADIATION LEVELS/RADIOLOGICAL EFFLUENTS EP-001-001 Revision 034 41.2 (17of 135)

AU2 Basis:

This IC addresses increased radiation levels as a result of water level decreases above irradiated fuel or events that have resulted, or may result, in UNPLANNED increases in radiation dose rates within plant buildings. These radiation increases represent a loss of control over radioactive material and may represent a potential degradation in the level of safety of the plant.

EAL #1 CAUTION NRC Information Notice 97-045 Supplement 1 identifies the potential for erratic indications from the Containment High Range Radiation Monitors (CHRRMs) as a result of Thermally Induced Currents (TIC) which may cause the CHRRM to read falsely high on a rapid thermal increase, and fail low intermittently on a rapid temperature decrease. The TICs induced in the Waterford CHRRM signal cable are anticipated to be negligible within 5 minutes. Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

The refueling pathway is a site specific combination of cavities, tubes, canals and pools. While a radiation monitor could detect an increase in dose rate due to a drop in the water level, it might not be a reliable indication of whether or not the fuel is covered.

For example, a refueling bridge ARM reading may increase due to planned evolutions such as head lift, or even a fuel assembly being raised in the manipulator mast. Also, a monitor could in fact be properly responding to a known event involving transfer or relocation of a source, stored in or near the fuel pool or responding to a planned evolution such as removal of the reactor head.

Generally, increased radiation monitor indications will need to combined with another indicator (or personnel report) of water loss.

For refueling events where the water level drops below the reactor vessel flange, classification would be via CU2. This event escalates to an Alert per AA2 if irradiated fuel outside the reactor vessel is uncovered. For events involving irradiated fuel in the reactor vessel, escalation would be via the Fission Product Barrier Matrix for events in operating modes 1-4.

AU2 EAL #2 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after an initial VALID full scale indication for area radiation monitors incapable of measuring 1000 times normal levels.

This EAL addresses increases in plant radiation levels that represent a loss of control of radioactive material resulting in a potential degradation in the level of safety of the plant.

This EAL excludes radiation level increases that result from planned activities such as use of radiographic sources and movement of radioactive waste materials. A specific list of ARMs is not required as it would restrict the applicability of the Threshold. The intent is to identify loss of control of radioactive material in any monitored area.

The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

This IC addresses an actual or substantial potential reduction in the level of safety of the plant as indicated by a radiological release that exceeds regulatory commitments for an extended period of time. Waterford 3 incorporates features intended to control the release of radioactive effluents to the environment.

Further, there are administrative controls established to prevent unintentional releases, or control and monitor intentional releases. The occurrence of extended, uncontrolled radioactive releases to the environment is indicative of degradation in these features and/or controls.

The ODCM multiples are specified in AU1 and AA1 only to distinguish between non-emergency conditions, and from each other. While these multiples obviously correspond to an offsite dose or dose rate, the emphasis in classifying these events is the degradation in the level of safety of the plant, NOT the magnitude of the associated dose or dose rate.

Releases should not be prorated or averaged. For example, a release exceeding 600 times ODCM limits for 5 minutes does not meet the threshold for this IC.

This Initiating Condition includes any release for which a release permit was not prepared, or a release that exceeds the conditions (e.g., minimum dilution flow, maximum discharge flow, alarm setpoints, etc.) on the applicable permit.

AA2 These events escalate from AU2 in that fuel activity has been released, or is anticipated due to fuel heatup. This IC applies to spent fuel requiring water coverage and is not intended to address spent fuel which is licensed for dry storage.

EAL #1 Indications may include instrumentation such as water level and local area radiation monitors, and personnel (e.g., refueling crew) reports. Depending on available level indication, the declaration may be based on indications of water makeup rate or decrease in Refueling Water Storage Pool level. Video cameras (Security or outage-related) may allow remote observation of level.

EAL #2 This EAL addresses radiation monitor indications of fuel uncovery and/or fuel damage.

Increased ventilation monitor readings may be indication of a radioactivity release from the fuel, confirming that damage has occurred. Increased background at the ventilation monitor due to water level decrease may mask increased ventilation exhaust airborne activity and needs to be considered.

While a radiation monitor could detect an increase in dose rate due to a drop in the water level, it might not be a reliable indication of whether or not the fuel is covered.

For example, a refueling bridge ARM reading may increase due to planned evolutions such as head lift, or even a fuel assembly being raised in the manipulator mast. Also, a monitor could in fact be properly responding to a known event involving transfer or relocation of a source, stored in or near the fuel pool or responding to a planned evolution such as removal of the reactor head.

Generally, increased radiation monitor indications will need to combined with another indicator (or personnel report) of water loss.

Escalation of this emergency classification level, if appropriate, would be based on AS1 or AG1.

AS1 Basis:

This IC addresses radioactivity releases that result in doses at or beyond the site boundary that exceed 10% of the EPA Protective Action Guides (PAGs).

Releases of this magnitude are associated with the failure of plant systems needed for the protection of the public.

EAL #1 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after an initial VALID reading > the reading shown for radiation monitors listed in EAL #1.

The monitor list in EAL #1 includes monitors on all potential release pathways (plant stack, primary-secondary leak, fuel handling accident).

EAL #2 Since dose assessment in EAL #2 is based on actual meteorology, whereas the monitor readings in EAL #1 are not, the results from these assessments may indicate that the classification is not warranted, or may indicate that a higher classification is warranted. For this reason, emergency implementing procedures should call for the timely performance of dose assessments using actual meteorology and release information. If the results of these dose assessments are available when the classification is made (e.g., initiated at a lower classification level), the dose assessment results override the monitor reading EALs.

EAL #3 CAUTION The Emergency Director shall make the declaration no later than 60 minutes (EAL time limit) after initial field survey results indicate closed window dose rates > 100 mR/hr and dose rates have not decreased below 100 mR/hr at or beyond the EAB.

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time. If dose assessment results are available, the classification should be based on EAL #2 instead of EAL #1.

Do not delay declaration awaiting dose assessment results.

AG1 Basis:

This IC addresses radioactivity releases that result in doses at or beyond the site boundary that exceed the EPA Protective Action Guides (PAGs). Public protective actions will be necessary. Releases of this magnitude are associated with the failure of plant systems needed for the protection of the public and likely involve fuel damage.

EAL #1 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after an initial VALID reading > the reading shown for radiation monitors listed in EAL #1.

CU1 Initiating Condition - NOTIFICATION OF UNUSUAL EVENT RCS leakage.

Operating Mode Applicability: Cold Shutdown (Mode 5)

Emergency Action Level(s):

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

1. RCS leakage results in the inability to maintain or restore level within Pressurizer or RCS level target band for > 15 minutes.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after RCS leakage results in the inability to maintain or restore level within Pressurizer or RCS level target band.

This IC is considered to be a potential degradation of the level of safety of the plant. The inability to maintain or restore level is indicative of loss of RCS inventory.

Relief valve normal operation should be excluded from this IC. However, a relief valve that operates and fails to close per design should be considered applicable to this IC if the relief valve cannot be isolated.

Prolonged loss of RCS Inventory may result in escalation to the Alert emergency classification level via either CA1 or CA3.

CU2 Initiating Condition - NOTIFICATION OF UNUSUAL EVENT UNPLANNED loss of RCS/reactor vessel inventory.

Operating Mode Applicability: Refueling (Mode 6)

Emergency Action Level(s): (1 or 2)

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

1. UNPLANNED RCS/reactor vessel level drop as indicated by either of the following:

a. RCS/reactor vessel water level drop below the reactor vessel flange for

> 15 minutes when the RCS/reactor vessel level band is established above the reactor vessel flange.

OR

b. RCS/reactor vessel water level drop below the RCS/reactor vessel level band for > 15 minutes when the RCS/reactor vessel level band is established below the reactor vessel flange.

OR

2. RCS/reactor vessel level cannot be monitored with a loss of RCS/reactor vessel inventory as indicated by an unexplained level rise in the containment sump or reactor drain tank.

Basis:

This IC is a precursor of more serious conditions and considered to be a potential degradation of the level of safety of the plant.

Refueling evolutions that decrease RCS water level below the reactor vessel flange are carefully planned and procedurally controlled. An UNPLANNED event that results in water level decreasing below the reactor vessel flange, or below the planned RCS water level for the given evolution (if the planned RCS water level is already below the reactor vessel flange), warrants declaration of a NOUE due to the reduced RCS inventory that is available to keep the core covered.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 58.2 (34 of 135)

CU2 The allowance of 15 minutes was chosen because it is reasonable to assume that level can be restored within this time frame using one or more of the redundant means of refill that should be available. If level cannot be restored in this time frame then it may indicate a more serious condition exists.

Continued loss of RCS Inventory will result in escalation to the Alert emergency classification level via either CA1 or CA3.

EAL #1 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) following either:

a. Initial RCS/reactor vessel water level drop below the reactor vessel flange when RCS/reactor vessel level band is established above the reactor vessel flange.

b. Initial RCS/reactor vessel water level drop below the RCS/reactor vessel level band when the RCS/reactor vessel level band is established below the reactor vessel flange.

This EAL involves a decrease in RCS level below the top of the reactor vessel flange that continues for 15 minutes due to an UNPLANNED event. This EAL is not applicable to decreases in flooded reactor cavity level, which is addressed by AU2 EAL1, until such time as the level decreases to the level of the vessel flange.

If reactor vessel level continues to decrease and reaches the Bottom ID of the RCS Loop (12 ft. MSL for these ICs) then escalation to CA1 would be appropriate.

EAL #2 This EAL addresses conditions in the refueling mode when normal means of core temperature indication and RCS level indication may not be available. Redundant means of reactor vessel level indication will normally be installed (including the ability to monitor level visually) to assure that the ability to monitor level will not be interrupted. However, if all level indication were to be lost during a loss of RCS inventory event, the operators would need to determine that reactor vessel inventory loss was occurring by observing sump and tank level changes. Sump and tank level increases must be evaluated against other

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 59.2 (35 of 135)

CU2 potential sources of leakage such as cooling water sources inside the containment to ensure they are indicative of RCS leakage.

Escalation to the Alert emergency classification level would be via either CA1 or CA3.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 60.2 (36 of 135)

CU3 Initiating Condition - NOTIFICATION OF UNUSUAL EVENT UNPLANNED loss of decay heat removal capability with irradiated fuel in the reactor vessel.

Operating Mode Applicability: Cold Shutdown (Mode 5)

Refueling (Mode 6)

Emergency Action Level(s): (1 or 2)

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

1. UNPLANNED event results in RCS temperature exceeding the Technical Specification cold shutdown temperature limit OR

2. Loss of all RCS temperature and RCS/reactor vessel level indication for > 15 minutes.

Basis:

This IC is a precursor of more serious conditions and, as a result, is considered to be a potential degradation of the level of safety of the plant. In cold shutdown the ability to remove decay heat relies primarily on forced cooling flow. Operation of the systems that provide this forced cooling may be jeopardized due to the unlikely loss of electrical power or RCS inventory. Since the RCS usually remains intact in the cold shutdown mode a large inventory of water is available to keep the core covered.

During refueling the level in the reactor vessel will normally be maintained above the reactor vessel flange. Refueling evolutions that decrease water level below the reactor vessel flange are carefully planned and procedurally controlled. Loss of forced decay heat removal at reduced inventory may result in more rapid increases in RCS/reactor vessel temperatures depending on the time since shutdown.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 61.2 (37 of 135)

CU3 CAUTION Using EAL #2 the Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after a loss of all RCS temperature and RCS/reactor vessel level indication.

Normal means of core temperature indication and RCS level indication may not be available in the refueling mode. Redundant means of reactor vessel level indication are therefore procedurally installed to assure that the ability to monitor level will not be interrupted. However, if all level and temperature indication were to be lost in either the cold shutdown of refueling modes, EAL 2 would result in declaration of an Unusual Event if both temperature and level indication cannot be restored within 15 minutes from the loss of both means of indication.

Escalation to Alert would be via CA1 based on an inventory loss or CA3 based on exceeding its temperature criteria.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 62.2 (38 of 135)

CU5 Initiating Condition - NOTIFICATION OF UNUSUAL EVENT

1. a. AC power capability to safety busses reduced to a single power source

> 15 minutes AND

b. Any additional single power source failure will result in station blackout.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after AC power capability to safety busses has been reduced to a single power source and any additional single power source failure will result in a station blackout.

The condition indicated by this IC is the degradation of the offsite and onsite AC power systems such that any additional single failure would result in a station blackout. This condition could occur due to a loss of offsite power with a concurrent failure of all but one emergency generator to supply power to its emergency busses. The subsequent loss of this single power source would escalate the event to an Alert in accordance with CA5.

Fifteen minutes was selected as a threshold to exclude transient or momentary losses of power.

When temporary emergency diesels (TEDs) are used to supplement onsite AC power for safety busses in the event diesels are lost, they are credited in this EAL. The EAL condition does not apply unless the TED also failed.

AC power capability to safety busses reduced to a single power source > 15 minutes such that any additional single failure would result in station blackout.

Operating Mode Applicability: Cold Shutdown (Mode 5)

Refueling (Mode 6)

Emergency Action Level(s):

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after indication of less than 108 volts on required vital DC bus.

This IC refers to loss of vital DC power from the 3A-DC, 3B-DC or 3AB-DC busses dependant upon designated protected train operability status.

The purpose of this IC and its associated 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.

It is intended that the loss of the operating (operable) train is to be considered. If this loss results in the inability to maintain cold shutdown, the escalation to an Alert will be in accordance with CA3.

Fifteen minutes was selected as a threshold to exclude transient or momentary power losses.

1. < 108 volts on required vital DC bus > 15 minutes.

Operating Mode Applicability: Cold Shutdown (Mode 5)

Refueling (Mode 6)

Emergency Action Level(s):

1. UNPLANNED sustained positive startup rate observed on nuclear instrumentation.

Basis:

This IC addresses criticality events that occur in Cold Shutdown or Refueling modes such as fuel mis-loading events and inadvertent dilution events. This IC indicates a potential degradation of the level of safety of the plant, warranting a NOUE classification.

This condition can be identified using the startup rate meter. The term sustained is used in order to allow exclusion of expected short term positive startup rates from planned fuel bundle or control rod movements during core alteration. These short term positive startup rates are the result of the increase in neutron population due to subcritical multiplication.

Escalation would be by Emergency Director judgment.

1. Loss of all Table C2 onsite communication methods affecting the ability to perform routine operations.

OR

2. Loss of all Table C3 offsite communication methods affecting the ability to perform offsite notifications.

Basis:

The purpose of this IC and its associated EALs is to recognize a loss of communications capability that either defeats the plant operations staff ability to perform routine tasks necessary for plant operations or the ability to communicate issues with offsite authorities. The loss of offsite communications ability is expected to be significantly more comprehensive than the condition addressed by 10 CFR 50.72.

The availability of one method of ordinary offsite communications is sufficient to inform federal, state, and local authorities of plant issues. This EAL is intended to be used only when extraordinary means (e.g., relaying of information from radio transmissions, individuals being sent to offsite locations, etc.) are being utilized to make communications possible.

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

OR

2. RCS/reactor vessel level cannot be monitored for > 15 minutes with a loss of RCS/reactor vessel inventory as indicated by an unexplained level rise in containment sump or reactor drain tank.

Basis:

These EALs serve as precursors to a loss of ability to adequately cool the fuel.

The magnitude of this loss of water indicates that makeup systems have not been effective and may not be capable of preventing further reactor vessel level decrease and potential core uncovery. This condition will result in a minimum emergency classification level of an Alert.

EAL #1 The inability to restore and maintain level after reaching this setpoint would be indicative of a failure of the RCS barrier.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 67.2 (43 of 135)

CA1 EAL #2 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after the RCS/reactor vessel level is unable to be monitored with a loss of RCS/reactor vessel inventory as indicated by an unexplained level rise in containment sump or reactor drain tank.

In the cold shutdown mode, normal RCS level and reactor vessel level instrumentation systems will usually be available. In the refueling mode, normal means of reactor vessel level indication may not be available. Redundant means of reactor vessel level indication will usually be installed (including the ability to monitor level visually) to assure that the ability to monitor level will not be interrupted. However, if all level indication were to be lost during a loss of RCS inventory event, the operators would need to determine that reactor vessel inventory loss was occurring by observing sump and tank level changes. Sump and tank level increases must be evaluated against other potential sources of leakage such as cooling water sources inside the containment to ensure they are indic ative of RCS leakage.

If reactor vessel level continues to lower then escalation to Site Area Emergency will be via CS1.

If an RCS heat removal system is in operation within this time frame and RCS temperature is being reduced, the EAL is not applicable.

OR Note: EAL #2 does not apply in solid plant conditions.

2. An UNPLANNED event results in RCS pressure increase > 10 psi due to a loss of RCS cooling.

Basis:

EAL #1 CAUTION The Emergency Director shall make the declaration no later than the time durations listed in Table C1 (EAL time limit) for an unplanned event resulting in RCS temperature > Technical Specification cold shutdown temperature limit.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 69.2 (45 of 135)

CA3 The RCS Reheat Duration Threshold table addresses complete loss of functions required for core cooling for greater than 60 minutes during refueling and cold shutdown modes when RCS integrity is established. RCS integrity should be considered to be in place when the RCS pressure boundary is in its normal condition for the cold shutdown mode of operation (e.g., no freeze seals or nozzle dams). The 60 minute time frame should allow sufficient time to restore cooling without there being a substantial degradation in plant safety.

The RCS Reheat Duration Threshold table also addresses the complete loss of functions required for core cooling for greater than 20 minutes during refueling and cold shutdown modes when CONTAINMENT CLOSURE is established but RCS integrity is not established or RCS inventory is reduced (e.g., mid-loop operation). As discussed above, RCS integrity should be assumed to be in place when the RCS pressure boundary is in its normal condition for the cold shutdown mode of operation (e.g., no freeze seals or nozzle dams). The allowed 20 minute time frame was included to allow operator action to restore the heat removal function, if possible.

Finally, the EAL addresses complete loss of functions required for core cooling during refueling and cold shutdown modes when neither CONTAINMENT CLOSURE nor RCS integrity are established.

The (*) indicates that this EAL is not applicable if actions are successful in restoring an RCS heat removal system to operation and RCS temperature is being reduced within the specified time frame.

EAL #2 The 10 psi pressure increase addresses situations where, due to high decay heat loads, the time provided to restore temperature control, should be less than 60 minutes. The RCS pressure setpoint chosen should be 10 psi or the lowest pressure that the site can read on installed Control Board instrumentation that is equal to or greater than 10 psi.

Escalation to Site Area Emergency would be via CS1 should boiling result in significant reactor vessel level loss leading to core uncovery.

A loss of Technical Specification components alone is not intended to constitute an Alert. The same is true of a momentary UNPLANNED excursion above the Technical Specification cold shutdown temperature limit when the heat removal function is available.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 70.2 (46 of 135)

CA3 The Emergency Director must remain alert to events or conditions that lead to the conclusion that exceeding the EAL is IMMINENT. If, in the judgment of the Emergency Director, an IMMINENT situation is at hand, the classification should be made as if the threshold has been exceeded.

CA5 Initiating Condition - ALERT Loss of all offsite and all onsite AC power to safety busses > 15 minutes.

Operating Mode Applicability: Cold Shutdown (Mode 5)

Refueling (Mode 6)

Defueled Emergency Action Level(s):

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition will likely exceed the applicable time.

1. Loss of all offsite and all onsite AC power to safety busses > 15 minutes.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after a loss of all offsite and all onsite AC power to safety busses.

Loss of all AC power compromises all plant safety systems requiring electric power including Shutdown Cooling, ECCS, Containment Heat Removal, Spent Fuel Heat Removal and the Ultimate Heat Sink.

The event can be classified as an Alert when in cold shutdown, refueling, or defueled mode because of the significantly reduced decay heat and lower temperature and pressure, increasing the time to restore one of the emergency busses, relative to that specified for the Site Area Emergency EAL.

When temporary emergency diesels (TEDs) are used to supplement onsite AC power for safety busses in the event diesels are lost, they are credited in this EAL. The EAL condition does not apply unless the TED also failed.

Escalating to Site Area Emergency, if appropriate, is by Abnormal Radiation Levels / Radiological Effluent (Tab A) ICs.

Basis:

Under the conditions specified by this IC, continued decrease in RCS/reactor vessel level is indicative of a loss of inventory control. Inventory loss may be due to an RCS breach, pressure boundary leakage, or continued boiling in the reactor vessel. Thus, declaration of a Site Area Emergency is warranted.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 73.2 (49 of 135)

CS1 Escalation to a General Emergency is via CG1 or AG1.

EAL #3 CAUTION The Emergency Director shall make the declaration no later than 30 minutes (EAL time limit) of the RCS/reactor vessel level being unable to be monitored with a loss of RCS/reactor vessel inventory as indicated in EAL #3.

In the cold shutdown mode, normal RCS level and reactor vessel level instrumentation systems will usually be available. In the refueling mode, normal means of reactor vessel level indication may not be available. Redundant means of reactor vessel level indication will usually be installed (including the ability to monitor level visually) to assure that the ability to monitor level will not be interrupted. However, if all level indication were to be lost during a loss of RCS inventory event, the operators would need to determine that reactor vessel inventory loss was occurring by observing sump and tank level changes. Sump and tank level increases must be evaluated against other potential sources of leakage such as cooling water sources inside the containment to ensure they are indicative of RCS leakage.

The 30-minute duration allows sufficient time for actions to be performed to recover inventory control equipment.

CAUTION NRC Information Notice 97-045 Supplement 1 identifies the potential for erratic indications from the Containment High Range Radiation Monitors (CHRRMs) as a result of Thermally Induced Currents (TIC) which may cause the CHRRM to read falsely high on a rapid thermal increase, and fail low intermittently on a rapid temperature decrease. The TICs induced in the Waterford CHRRM signal cable are anticipated to be negligible within 5 minutes. Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

As water level in the reactor vessel lowers, the dose rate above the core will increase. The dose rate due to this core shine should result in site specific monitor indication and possible alarm.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 75.2 (51 of 135)

CG1 Basis:

CAUTION The Emergency Director shall make the declaration no later than 30 minutes (EAL time limit) after Core Exit Thermocouples initially indicated superheat and EAL 1.b. is met.

This IC represents the inability to restore and maintain reactor vessel level to above the top of active fuel with containment challenged. Fuel damage is probable if reactor vessel level cannot be restored, as available decay heat will cause boiling, further reducing the reactor vessel level. With the CONTAINMENT breached or challenged then the potential for unmonitored fission product release to the environment is high. This represents a direct path for radioactive inventory to be released to the environment. This is consistent with the definition of a GE.

The GE is declared on the occurrence of the loss or IMMINENT loss of function of all three barriers.

A number of variables can have a significant impact on heat removal capability challenging the fuel clad barrier. Examples include: mid-loop, reduced level/flange level, head in place, cavity flooded, RCS venting strategy, decay heat removal system design, vortexing pre-disposition, steam generator U-tube draining.

Analysis indicates that core damage may occur within an hour following continued core uncovery therefore, 30 minutes was conservatively chosen.

If CONTAINMENT CLOSURE is re-established prior to exceeding the 30 minute core uncovery time limit then escalation to GE would not occur.

In the early stages of a core uncovery event, it is unlikely that hydrogen buildup due to a core uncovery could result in an explosive mixture of dissolved gasses in Containment. However, Containment monitoring and/or sampling should be performed to verify this assumption and a General Emergency declared if it is determined that an explosive mixture exists.

EAL #2 CAUTION The Emergency Director shall make the declaration no later than 30 minutes (EAL time limit) from the loss of the ability to monitor RCS/reactor vessel level with core uncovery indicated by any parameter listed in EAL 2.a. and a containment challenge as identified by any EAL 2.b indication.

COLD SHUTDOWN/REFUELING SYSTEM MALFUNCTION EP-001-001 Revision 034 76.2 (52 of 135)

CG1 Sump and tank level increases must be evaluated against other potential sources of leakage such as cooling water sources inside the containment to ensure they are indicative of RCS leakage.

In the cold shutdown mode, normal RCS level and reactor vessel level instrumentation systems will usually be available. In the refueling mode, normal means of reactor vessel level indication may not be available. Redundant means of reactor vessel level indication will usually be installed (including the ability to monitor level visually) to assure that the ability to monitor level will not be interrupted. However, if all level indication were to be lost during a loss of RCS inventory event, the operators would need to determine that reactor vessel inventory loss was occurring by observing sump and tank level changes. Sump and tank level increases must be evaluated against other potential sources of leakage such as cooling water sources inside the containment to ensure they are indicative of RCS leakage.

CAUTION NRC Information Notice 97-045 Supplement 1 identifies the potential for erratic indications from the Containment High Range Radiation Monitors (CHRRMs) as a result of Thermally Induced Currents (TIC) which may cause the CHRRM to read falsely high on a rapid thermal increase, and fail low intermittently on a rapid temperature decrease. The TICs induced in the Waterford CHRRM signal cable are anticipated to be negligible within 5 minutes. Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

As water level in the reactor vessel lowers, the dose rate above the core will increase. The dose rate due to this core shine should result in site specific monitor indication and possible alarm.

General Bases:

The logic used for these Initiating Conditions reflects the following considerations:

The Fuel Clad Barrier and the RCS Barrier are weighted more heavily than the Containment Barrier. Unusual Event ICs associated with RCS and Fuel Clad Barriers are addressed under System Malfunction (S) ICs.

At the Site Area Emergency level, there must be some ability to dynamically assess how far present conditions are from the threshold for a General Emergency. For example, if Fuel Clad and RCS Barrier Loss EALs existed, that, in addition to offsite dose assessments, would require continual assessments of radioactive inventory and containment integrity.

Alternatively, if both Fuel Clad and RCS 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 deteriorates must be maintained. For example, RCS leakage steadily increasing would represent an increasing risk to public health and safety.

The Containment Barrier should not be declared lost or potentially lost based on exceeding Technical Specification action statement criteria, unless there is an event in progress requiring mitigation by the Containment barrier. When no event is in progress (Loss or Potential Loss of either Fuel Clad and/or RCS) the Containment Barrier status is addressed by Technical Specifications.

The radiation monitor values given are assumed valid when the primary sample panel valves are open receiving flow from the RCS.

The site specific value corresponds to 300 Ci/gm I-131 equivalent. Assessment by the EAL Task Force indicates that this amount of coolant activity is well above that expected for iodine spikes and corresponds to less than 5% fuel clad damage. This amount of radioactivity indicates significant clad damage and thus the Fuel Clad Barrier is considered lost.

CAUTION NRC Information Notice 97-045 Supplement 1 identifies the potential for erratic indications from the Containment High Range Radiation Monitors (CHRRMs) as a result of Thermally Induced Currents (TIC) which may cause the CHRRM to read falsely high on a rapid thermal increase, and fail low intermittently on a rapid temperature decrease. The TICs induced in the Waterford CHRRM signal cable are anticipated to be negligible within 5 minutes. Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

This reading is a value which indicates the release of reactor coolant, with elevated activity indicative of fuel damage, into the containment.

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 radiation monitor value is higher than that specified for RCS barrier Loss EAL RCB3. Thus, this EAL indicates a loss of both the fuel clad barrier and RCS barrier that appropriately escalates the emergency classification to a Site Area Emergency.

RCS Leak Rate (RCB2)

Loss: RCS leak rate > available makeup capacity as indicated by RCS subcooling < 28º F.

Potential Loss: UNISOLABLE RCS leak > 44 gpm.

Basis:

Loss This EAL addresses conditions where leakage from the RCS is greater than available inventory control capacity such that a loss of subcooling has occurred. The loss of subcooling is the fundamental indication that the inventory control systems are inadequate in maintaining RCS pressure and inventory against the mass loss through the leak.

Potential Loss This EAL is based on the apparent inability to maintain normal liquid inventory within the RCS by normal operation of the Chemical and Volume Control System which is considered to be the flow rate equivalent to one charging pump discharging to the charging header. Isolating letdown is a standard abnormal operating procedure action and may prevent unnecessary classifications when a non-RCS leakage path such as a CVCS leak exists. The intent of this condition is met if attempts to isolate Letdown are NOT successful. Additional charging pumps being required is indicative of a substantial RCS leak.

This EAL addresses the full spectrum of Steam Generator (SG) tube rupture events in conjunction with Containment barrier Loss EALs. It addresses RUPTURED SG(s) for which the leakage is large enough to cause actuation (either automatic or manual) of ECCS (SI). This is consistent to the RCS leak rate barrier Potential Loss EAL.

By itself, this EAL will result in the declaration of an Alert. However, if the SG is also FAULTED (i.e., two barriers failed), the declaration escalates to a Site Area Emergency in accordance with Containment barrier Loss EAL CNB3.

Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

The radiation monitor reading is a value which indicates the release of reactor coolant to the containment.

This reading is less than that specified for Fuel Clad barrier EAL FCB4. Thus, this EAL is indicative of a RCS leak only. If the radiation monitor reading increased to that specified by Fuel Clad barrier EAL, fuel damage would also be indicated.

Loss: Not Applicable Potential Loss: RCS pressure dropping due to primary relief not reseating Basis:

There is no Loss EAL associated with this item.

The setpoint for the pressurizer code safety valves is 2500 psia +/- 3%. Their purpose is to provide RCS overpressure protection. The safety valves pass sufficient pressurizer steam to limit the RCS pressure to 2750 psia (110 % of design) following a complete loss of turbine generator load without simultaneous reactor trip. In the event of a primary relief valve lifting and not reseating the loss of mass inventory of the RCS is large enough to uncover the core in a short period of time.

Basis:

This EAL addresses any other factors that are to be used by the Emergency Director in determining whether the RCS barrier is lost or potentially lost. In addition, the inability to monitor the barrier should also be incorporated in this EAL as a factor in Emergency Director judgment that the barrier may be considered lost or potentially lost.

The Containment Barrier includes the containment building and connections up to and including the outermost containment isolation valves. This barrier also includes the main steam, feedwater, and blowdown line extensions outside the containment building up to and including the outermost secondary side isolation valve.

Safety Function Status (CNB1)

Loss: Not Applicable Potential Loss:

Containment Temperature and Pressure Control Safety Function NOT met Basis:

There is no Loss EAL associated with this item.

Containment Temperature and Pressure Control Safety Function not met indicates an extreme challenge to the safety function derived from appropriate instrument readings and/or sampling results, and thus represents a potential loss of containment.

Conditions leading to a Containment Temperature and Pressure Control Safety Function not met condition result from RCS barrier and/or Fuel Clad Barrier Loss. Thus, this threshold is primarily a discriminator between Site Area Emergency and General Emergency representing a potential loss of the third barrier.

b. Explosive mixture exists inside containment OR

c. 1. Containment pressure > 17.7 PSIA AND

2. LESS THAN one full train of Containment Spray operating (1750 gpm)

Basis:

Loss Rapid unexplained loss of pressure (i.e., not attributable to containment spray or condensation effects) following an initial pressure increase from a primary or secondary high energy line break indicates a loss of containment integrity.

Containment pressure and sump levels should increase as a result of mass and

FISSION PRODUCT BARRIER DEGRADATION EP-001-001 Revision 034 102.2 (78 of 135)

Containment Barrier Emergency Action Levels:

energy release into containment from a LOCA. Thus, sump level or pressure not increasing indicates containment bypass and a loss of containment integrity.

This indicator relies on operator recognition of an unexpected response for the condition and therefore does not have a specific value associated with it. The unexpected response is important because it is the indicator for a containment bypass condition.

Potential Loss a.

The site specific pressure is based on the containment design pressure.

Potential Loss b.

Existence of an explosive mixture means a hydrogen and oxygen concentration of at least the lower deflagration limit curve exists (refer to Severe Accident Management Guidelines Calculation Aid #7, Containment Challenge due to Hydrogen Combustion).

Potential Loss c.

This EAL represents a potential loss of containment in that the containment heat removal/depressurization system (e.g., containment sprays, ice condenser fans, etc., but not including containment venting strategies) are either lost or performing in a degraded manner, as indicated by containment pressure greater than the setpoint at which the equipment was supposed to have actuated or Containment Spray pump providing LESS THAN 1750 gpm flow. Credit is not taken for Containment Fan Coolers in this EAL as mitigating Containment Spray losses.

There is no Loss EAL associated with this item.

The conditions in these EALs represent an IMMINENT core melt sequence which, if not corrected, could lead to vessel failure and an increased potential for containment failure. In conjunction with the Core Cooling and RCS Leakage criteria in the Fuel and RCS barrier columns, this threshold would result in the declaration of a General Emergency -- loss of two barriers and the potential loss of a third. If the function restoration procedures are ineffective, there is no "success" path.

FISSION PRODUCT BARRIER DEGRADATION EP-001-001 Revision 034 104.2 (80 of 135)

Containment Barrier Emergency Action Levels:

The function restoration procedures are those emergency operating procedures that address the recovery of the core cooling critical safety functions. The procedure is considered effective if the temperature is decreasing or if the vessel water level is increasing.

Whether or not the procedures will be effective should be apparent within 15 minutes. The Emergency Director should make the declaration as soon as it is determined that the procedures have been, or will be ineffective.

SG Secondary Side Release With Primary to Secondary Leakage (CNB4)

Loss:

a.

RUPTURED SG is also FAULTED outside of containment OR

b.

1. Primary-to-Secondary leakrate >10 gpm AND

2. UNISOLABLE steam release from affected SG to the environment Potential Loss: Not Applicable Basis:

This loss EAL recognizes that SG tube leakage can represent a bypass of the Containment barrier as well as a loss of the RCS barrier.

Users should realize that the two loss thresholds could be considered redundant.

This was recognized during the development process. The inclusion of an EAL that uses Emergency Procedure commonly used terms like RUPTURED and FAULTED adds to the ease of the classification process and has been included based on this human factor concern.

This EAL results in an Unusual Event for smaller breaks that; (1) do not exceed the normal charging capacity EAL in RCS leak rate barrier Potential Loss, or (2) do not result in ECCS actuation in RCS SG tube rupture barrier Loss. For larger breaks, RCS barrier criteria would result in an Alert. For SG tube ruptures which may involve multiple steam generators or UNISOLABLE secondary line breaks, this condition would exist in conjunction with RCS barrier conditions and would result in a Site Area Emergency. Escalation to General Emergency would be based on "Potential Loss" of the Fuel Clad Barrier.

Loss a.

This EAL addresses the condition in which a RUPTURED steam generator is also FAULTED. This condition represents a bypass of the RCS and containment barriers and is a subset of the second EAL. In conjunction with RCS leak rate barrier loss EAL RCB2, this would always result in the declaration of a Site Area Emergency.

FISSION PRODUCT BARRIER DEGRADATION EP-001-001 Revision 034 106.2 (82 of 135)

Loss b.

This EAL addresses SG tube leaks that exceed 10 gpm in conjunction with an UNISOLABLE release path to the environment from the affected steam generator. The threshold for establishing the UNISOLABLE secondary side release is intended to be a prolonged release of radioactivity from the RUPTURED steam generator directly to the environment. This could be expected to occur when the main condenser is unavailable to accept the contaminated steam (i.e., SG tube rupture with concurrent loss of off-site power and the RUPTURED steam generator is required for plant cooldown or a stuck open relief valve or failed open atmospheric dump valve). If the main condenser is available, there may be releases via air ejectors, gland seal exhausters, and other similar controlled, and often monitored, pathways. Also, releases from the Steam Driven Emergency Feedwater Pump Turbine result in a very small minor release that can be isolated with the MS-401A and B valves. These pathways do not meet the intent of an UNISOLABLE release path to the environment. These minor releases are assessed using Abnormal Radiation Levels / Radiological Effluent ICs (TAB A).

Containment Barrier Emergency Action Levels:

Containment Isolation Failure or Bypass (CNB5)

Loss:

i.

UNISOLABLE breach of containment AND

b. Direct downstream pathway to the environment exists after containment isolation signal Potential Loss: Not Applicable Basis:

This EAL addresses incomplete containment isolation that allows a direct release to the environment.

The use of the modifier direct in defining the release path discriminates against release paths through interfacing liquid systems. The existence of an in-line charcoal filter does not make a release path indirect since the filter is not effective at removing fission product noble gases. Typical filters have an efficiency of 95-99% removal of iodine. Given the magnitude of the core inventory of iodine, significant releases could still occur. In addition, since the fission product release would be driven by boiling in the reactor vessel, the high humidity in the release stream can be expected to render the filters ineffective in a short period. Therefore, a failure of a containment penetration in the annulus with frequent cycling of the shield building ventilation system (a filtered release path) meets the loss criteria of this EAL and constitutes a loss of the containment barrier.

There is no Potential Loss EAL associated with this item.

FISSION PRODUCT BARRIER DEGRADATION EP-001-001 Revision 034 108.2 (84 of 135)

Containment Barrier Emergency Action Levels:

Significant Radioactive Inventory in Containment (CNB6)

Loss: Not Applicable Potential Loss: Containment High Range Radiation Monitor (ARM-IRE-5400AS or ARM-IRE-5400BS) > 4000 R/hr.

Basis:

There is no Loss EAL associated with this item.

CAUTION NRC Information Notice 97-045 Supplement 1 identifies the potential for erratic indications from the Containment High Range Radiation Monitors (CHRRMs) as a result of Thermally Induced Currents (TIC) which may cause the CHRRM to read falsely high on a rapid thermal increase, and fail low intermittently on a rapid temperature decrease. The TICs induced in the Waterford CHRRM signal cable are anticipated to be negligible within 5 minutes. Because of this phenomenon, any trends or alarms on the CHRRMs should be validated by comparison to the containment low range/area radiation monitors and Air Monitoring Systems trends before actions are taken.

The containment high range radiation monitor reading is a value which indicates significant fuel damage well in excess of the EALs associated with both loss of Fuel Clad and loss of RCS barriers. A major release of radioactivity requiring off-site 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.

Because the monitor reading exceeds the readings for Fuel Clad Barrier loss in FCB4 and RCS Barrier loss in RCB3, the Emergency Director should declare a General Emergency when this value on the Containment High Range Radiation Monitor is exceeded as a loss of two barriers (fuel clad and RCS) and potential loss of the third (containment).

FISSION PRODUCT BARRIER DEGRADATION EP-001-001 Revision 034 109.2 (85 of 135)

Containment Barrier Emergency Action Levels:

Emergency Director Judgment (CNB7)

Any condition in the opinion of the Emergency Director that indicates Loss or Potential Loss of the Containment Barrier.

Basis:

This EAL addresses any other factors that are to be used by the Emergency Director in determining whether the Containment barrier is lost or potentially lost.

In addition, the inability to monitor the barrier should also be incorporated in this EAL as a factor in Emergency Director judgment that the barrier may be considered lost or potentially lost.

The Containment barrier should not be declared lost or potentially lost based on exceeding Technical Specification action statement criteria, unless there is an event in progress requiring mitigation by the Containment barrier. When no event is in progress (Loss or Potential Loss of either Fuel Clad and/or RCS) the Containment barrier status is addressed by Technical Specifications.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 111.2 (87 of 135)

HU1 Confirmed SECURITY CONDITION or threat which indicates a potential degradation in the level of safety of the plant.

Operating Mode Applicability: All Emergency Action Level(s): (1 or 2 or 3)

1. A SECURITY CONDITION that does not involve a HOSTILE ACTION as reported by the Waterford 3 Security Shift Supervision OR

2. A credible site specific security threat notification OR

3. A validated notification from NRC providing information of an aircraft threat.

Basis:

NOTE: Timely and accurate communication between Security Shift Supervision and the Control Room is crucial for the implementation of effective Security EALs.

Security events which do not represent a potential degradation in the level of safety of the plant are reported under 10 CFR 73.71 or in some cases under 10 CFR 50.72. Security events assessed as HOSTILE ACTIONS are classifiable under HA1, HS1 and HG1.

A higher initial classification could be made based upon the nature and timing of the security threat and potential consequences. Consideration shall be given to upgrading the emergency response status and emergency classification in accordance with the Safeguards Contingency Plan and Emergency Plan.

EAL #1 The Security Shift Supervisor is the designated individual on-site qualified and trained to confirm that a security event is occurring or has occurred. Training on security event classification confirmation is closely controlled due to the strict secrecy controls placed on the plant Safeguards Contingency Plan.

This EAL is based on the Safeguards Contingency Plan. The Safeguards Contingency Plan is based on guidance provided in NEI 03-12.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 112.2 (88 of 135)

HU1 EAL #2 This EAL is included to ensure that appropriate notifications for the security threat are made in a timely manner. This includes information of a credible threat.

Only the plant to which the specific threat is made need declare the Notification of Unusual Event.

The determination of credible is made through use of information found in the Safeguards Contingency Plan.

EAL #3 The intent of this EAL is to ensure that notifications for the aircraft threat are made in a timely manner and that Offsite Response Organizations and plant personnel are at a state of heightened awareness regarding the credible threat. It is not the intent of this EAL to replace existing non-hostile related EALs involving aircraft.

This EAL is met when a plant receives information regarding an aircraft threat from NRC. Validation is performed by calling the NRC or by other approved methods of authentication. Only the plant to which the specific threat is made need declare the Unusual Event.

The NRC Headquarters Operations Officer (HOO) will communicate to the licensee if the threat involves an airliner (airliner is meant to be a large aircraft with the potential for causing significant damage to the plant). The status and size of the plane may be provided by NORAD through the NRC.

Escalation to Alert via HA1 would be appropriate if the threat involves an airliner within 30 minutes of the plant.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 113.2 (89 of 135)

HU2 Other conditions exist which in the judgment of the Emergency Director warrant declaration of an Unusual Event.

Operating Mode Applicability: All Emergency Action Level(s):

1.

Other conditions exist which in the judgment of the Emergency Director indicate that events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.

Basis:

This EAL addresses unanticipated conditions not addressed explicitly elsewhere but that warrant declaration of an emergency because conditions exist which are believed by the Emergency Director to fall under the Unusual Event emergency classification level.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 114.2 (90 of 135)

HU4 FIRE within the PROTECTED AREA not extinguished within 15 minutes of detection or EXPLOSION within the PROTECTED AREA.

Operating Mode Applicability: All Emergency Action Level(s): (1 or 2)

Note: The Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the duration has exceeded, or will likely exceed, the applicable time.

1. FIRE not extinguished within 15 minutes of Control Room notification or verification of a Control Room FIRE alarm in any of the following areas:

Containment Fuel Handling Building Reactor Auxiliary Building Cooling Tower Areas OR

2. EXPLOSION within the PROTECTED AREA.

Basis:

This IC addresses the magnitude and extent of FIRES or EXPLOSIONS that may be potentially significant precursors of damage to safety systems. It addresses the FIRE / EXPLOSION, and not the degradation in performance of affected systems that may result.

As used here, detection is visual observation and report by plant personnel or sensor alarm indication.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 115.2 (91 of 135)

HU4 EAL #1 CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after a fire not extinguished in any of the areas identified in the EAL.

The 15 minute time period begins with a credible notification that a FIRE is occurring, or indication of a fire detection system alarm/actuation. Verification of a fire detection system alarm/actuation includes actions that can be taken within the Control Room or other nearby site specific location to ensure that it is not spurious. An alarm is assumed to be an indication of a FIRE unless it is disproved within the 15 minute period by personnel dispatched to the scene. In other words, a personnel report from the scene may be used to disprove a sensor alarm if received within 15 minutes of the alarm, but shall not be required to verify the alarm.

The intent of this 15 minute duration is to size the FIRE and to discriminate against small FIRES that are readily extinguished (e.g., smoldering waste paper basket).

EAL #2 This EAL addresses only those EXPLOSIONS of sufficient force to damage permanent structures or equipment within the PROTECTED AREA.

No attempt is made to assess the actual magnitude of the damage. The occurrence of the EXPLOSION is sufficient for declaration.

The Emergency Director also needs to consider any security aspects of the EXPLOSION, if applicable.

Escalation of this emergency classification level, if appropriate, would be based on HA4.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 116.2 (92 of 135)

HU5 Release of toxic, corrosive, asphyxiant, or flammable gases deemed detrimental to NORMAL PLANT OPERATIONS.

Operating Mode Applicability: All Emergency Action Level(s): (1 or 2)

1. Toxic, corrosive, asphyxiant or flammable gases in amounts that have or could adversely affect NORMAL PLANT OPERATIONS.

OR

1. Report by St. Charles Parish for evacuation or sheltering of site personnel based on an offsite event.

Basis:

This IC is based on the release of toxic, corrosive, asphyxiant or flammable gases of sufficient quantity to affect NORMAL PLANT OPERATIONS.

The fact that SCBAs may be worn does not eliminate the need to declare the event.

This IC is not intended to require significant assessment or quantification. It assumes an uncontrolled process that has the potential to affect plant operations.

This would preclude small or incidental releases, or releases that do not impact structures needed for plant operation.

An asphyxiant is a gas capable of reducing the level of oxygen in the body to dangerous levels. Most commonly, asphyxiants work by merely displacing air in an enclosed environment. This reduces the concentration of oxygen below the normal level of around 19%, which can lead to breathing difficulties, unconsciousness or even death.

Escalation of this emergency classification level, if appropriate, would be based on HA5.

1. Seismic event identified by any 2 of the following:

Seismic event confirmed by station seismic instrumentation Earthquake felt in plant National Earthquake Center.

OR

2. Tornado striking within PROTECTED AREA boundary or high winds > 100 mph.

OR

3. Internal flooding that has the potential to affect safety related equipment required by Technical Specifications for the current operating mode in any Table H1 area..

TABLE H1: Structures/Areas for HU6 and HA6 Containment Fuel Handling Building Reactor Auxiliary Building Cooling Tower Areas OR

4. Turbine failure resulting in casing penetration or damage to turbine or generator seals.

OR

5. Hurricane force winds (> 74 mph) expected to arrive on site in <12 hours as projected by the National Weather Service for a hurricane event.

OR

6. River water level at the intake structure > +27 FT MSL.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 118.2 (94 of 135)

HU6 Basis:

These EALs are categorized on the basis of the occurrence of an event of sufficient magnitude to be of concern to plant operators.

EAL #1 Damage may be caused to some portions of the site, but should not affect ability of safety functions to operate.

For plants with operable seismic instrumentation, an earthquake of sufficient intensity such that the seismic switches of the plant are activated is an indication of a classifiable earthquake.

As defined in the EPRI-sponsored Guidelines for Nuclear Plant Response to an Earthquake, dated October 1989, a "felt earthquake is an earthquake of sufficient intensity such that the vibratory ground motion is felt at the nuclear plant site and recognized as an earthquake based on a consensus of control room operators on duty at the time.

The National Earthquake Center can confirm if an earthquake has occurred in the area of the plant.

EAL #2 This EAL is based on a tornado striking (touching down) or high winds within the PROTECTED AREA.

Escalation of this emergency classification level, if appropriate, would be based on VISIBLE DAMAGE, or by other in plant conditions, via HA6.

EAL #3 This EAL addresses the effect of internal flooding caused by events such as component failures, equipment misalignment, or outage activity mishaps.

Escalation of this emergency classification level, if appropriate, would be via HA6, or by other plant conditions.

EAL #4 This EAL addresses main turbine rotating component failures of sufficient magnitude to cause observable damage to the turbine casing or to the seals of the turbine generator. Generator seal damage observed after generator purge does not meet the intent of this EAL because it did not impact normal operation of the plant.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 119.2 (95 of 135)

HU6 Of major concern is the potential for leakage of combustible fluids (lubricating oils) and gases (hydrogen cooling) to the plant environs. Actual FIRES and flammable gas build up are appropriately classified via HU4 and HU5.

This EAL is consistent with the definition of an Unusual Event while maintaining the anticipatory nature desired and recognizing the risk to non-safety related equipment.

Escalation of this emergency classification level, if appropriate, would be to HA6 based on damage done by PROJECTILES generated by the failure or in conjunction with a steam generator tube rupture. These latter events would be classified by the radiological (A) ICs or Fission Product Barrier (F) ICs.

EAL #5 This EAL addresses the potential for the site to experience high level (hurricane force) winds and associated flooding and storm surge over an extended period of time (usually several hours). This EAL is selected because it will generally be associated with significant levels of site severe weather response such as a potential precautionary shutdown, diesel testing, staff call-outs, etc. The site experiencing a hurricane can also be a precursor of more serious events. It is not necessary to declare this event based on issuance of a Hurricane Warning for St. Charles Parish alone.

EAL #6 This EAL addresses Mississippi River flooding. The levee system is designed to protect people and property from the most severe effects of river flooding.

The Waterford 3 UFSAR section 2.4 indicates that a flood less severe than the Probable Maximum Flood (PMF) but more severe than the Project Design Flood (PDF) may pose the greatest threat to the site in the event of a nearby levee failure. The UFSAR refers to Mississippi River water level of +27 ft. MSL as that corresponding level for such an event that includes appropriate conservatism.

Therefore, this level of flooding can also be a precursor of more serious events and is used as an EAL here.

HA1 Initiating Condition -- ALERT HOSTILE ACTION within the OWNER CONTROLLED AREA or airborne attack threat.

Operating Mode Applicability: All Emergency Action Level(s):

1. A HOSTILE ACTION is occurring or has occurred within the OWNER CONTROLLED AREA as reported by the Waterford 3 Security Shift Supervision.

OR

2. A validated notification from NRC of an airliner attack threat within 30 minutes of the site.

Basis:

NOTE: Timely and accurate communication between Security Shift Supervision and the Control Room is crucial for the implementation of effective Security EALs.

These EALs address the contingency for a very rapid progression of events, such as that experienced on September 11, 2001. They are not premised solely on the potential for a radiological release. Rather the issue includes the need for rapid assistance due to the possibility for significant and indeterminate damage from additional air, land or water attack elements.

The fact that the site is under serious attack or is an identified attack target with minimal time available for further preparation or additional assistance to arrive requires a heightened state of readiness and implementation of protective measures that can be effective (such as on-site evacuation, dispersal or sheltering).

EAL #1 This EAL addresses the potential for a very rapid progression of events due to a HOSTILE ACTION. It is not intended to address incidents that are accidental events or acts of civil disobedience, such as small aircraft impact, hunters, or physical disputes between employees within the OWNER CONTROLLED AREA.

Those events are adequately addressed by other EALs.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 121.2 (97 of 135)

HA1 Note that this EAL is applicable for any HOSTILE ACTION occurring, or that has occurred, in the OWNER CONTROLLED AREA. This includes Independent Spent Fuel Storage Installations that may be outside the PROTECTED AREA but still in the OWNER CONTROLLED AREA.

EAL #2 This EAL addresses the immediacy of an expected threat arrival or impact on the site within a relatively short time.

The intent of this EAL is to ensure that notifications for the airliner attack threat are made in a timely manner and that Offsite Response Organzations and plant personnel are at a state of heightened awareness regarding the credible threat.

Airliner is meant to be a large aircraft with the potential for causing significant damage to the plant.

This EAL is met when a plant receives information regarding an airliner attack threat from NRC and the airliner is within 30 minutes of the plant. Only the plant to which the specific threat is made need declare the Alert.

The NRC Headquarters Operations Officer (HOO) will communicate to the licensee if the threat involves an airliner (airliner is meant to be a large aircraft with the potential for causing significant damage to the plant). The status and size of the plane may be provided by NORAD through the NRC.

HA2 Initiating Condition -- ALERT Other conditions exist which in the judgment of the Emergency Director warrant declaration of an Alert Operating Mode Applicability: All Emergency Action Level(s):

1. Other conditions exist which in the judgment of the Emergency Director indicate that events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION. Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.

Basis:

This EAL addresses unanticipated conditions not addressed explicitly elsewhere but that warrant declaration of an emergency because conditions exist which are believed by the Emergency Director to fall under the Alert emergency classification level.

1. OP-901-502, Evacuation of Control Room & Subsequent Plant Shutdown requires Control Room evacuation.

Basis:

With the Control Room evacuated, additional support, monitoring and direction through the Technical Support Center and/or other emergency response facilities may be necessary.

Inability to establish plant control from outside the Control Room will escalate this event to a Site Area Emergency.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 124.2 (100 of 135)

HA4 Initiating Condition -- ALERT FIRE or EXPLOSION affecting the operability of plant safety systems required to establish or maintain safe shutdown.

Operating Mode Applicability: All Emergency Action Level(s):

Cooling Tower Areas Basis:

VISIBLE DAMAGE is used to identify the magnitude of the FIRE or EXPLOSION and to discriminate against minor FIRES and EXPLOSIONS.

The reference to structures containing safety systems or components is included to discriminate against FIRES or EXPLOSIONS in areas having a low probability of affecting safe operation. The significance here is not that a safety system was degraded but the fact that the FIRE or EXPLOSION was large enough to cause damage to these systems.

The use of VISIBLE DAMAGE should not be interpreted as mandating a lengthy damage assessment prior to classification. The declaration of an Alert and the activation of the Technical Support Center will provide the Emergency Director with the resources needed to perform detailed damage assessments.

The Emergency Director also needs to consider any security aspects of the EXPLOSION.

Escalation of this emergency classification level, if appropriate, will be based on System Malfunction (S), Fission Product Barrier Degradation (F) or Abnormal Radiation Levels/Radiological Effluent (A) ICs.

1. FIRE or EXPLOSION resulting in VISIBLE DAMAGE to any of the following structures containing safety systems or components or Control Room indication of degraded performance of those safety systems:

Operating Mode Applicability: All Emergency Action Level(s):

Note: If the equipment in the stated area was already inoperable, or out of service, before the event occurred, then this EAL should not be declared as it will have no adverse impact on the ability of the plant to safely operate or safely shutdown beyond that already allowed by Technical Specifications at the time of the event.

1. Access to a VITAL AREA is prohibited due to toxic, corrosive, asphyxiant or flammable gases which jeopardize operation of systems required to maintain safe operations or safely shutdown the reactor.

Basis:

Gases in a VITAL AREA can affect the ability to safely operate or safely shutdown the reactor.

The fact that SCBAs may be worn does not eliminate the need to declare the event.

Declaration should not be delayed for confirmation from atmospheric testing if the atmosphere poses an immediate threat to life and health or an immediate threat of severe exposure to gases. This could be based upon documented analysis, indication of personal ill effects from exposure, or operating experience with the hazards.

If the equipment in the stated area was already inoperable, or out of service, before the event occurred, then this EAL should not be declared as it will have no adverse impact on the ability of the plant to safely operate or safely shutdown beyond that already allowed by Technical Specifications at the time of the event.

An asphyxiant is a gas capable of reducing the level of oxygen in the body to dangerous levels. Most commonly, asphyxiants work by merely displacing air in an enclosed environment.

HA5 An uncontrolled release of flammable gasses within a facility structure has the potential to affect safe operation of the plant by limiting either operator or equipment operations due to the potential for ignition and resulting equipment damage/personnel injury.

Flammable gasses, such as hydrogen and acetylene, are routinely used to maintain plant systems (hydrogen) or to repair equipment/components (acetylene - used in welding). This EAL assumes concentrations of flammable gasses which can ignite/support combustion.

Escalation of this emergency classification level, if appropriate, will be based on System Malfunction (S), Fission Product Barrier Degradation (F) or Abnormal Radiation Levels / Radioactive Effluent (A) ICs.

5. Vehicle crash resulting in VISIBLE DAMAGE to any of the table H1 structures containing safety systems or components or Control Room indication of degraded performance of those safety systems.

TABLE H1: Structures/Areas for HU6 and HA6 Containment Fuel Handling Building Reactor Auxiliary Building Cooling Tower Areas Basis:

These EALs escalate from HU6 in that the occurrence of the event has resulted in VISIBLE DAMAGE to plant structures or areas containing equipment necessary for a safe shutdown, or has caused damage to the safety systems in those structures evidenced by Control Room indications of degraded system response or performance. The occurrence of VISIBLE DAMAGE and/or degraded system response is intended to discriminate against lesser events. The initial report should not be interpreted as mandating a lengthy damage assessment prior to classification. No attempt is made in these EALs to assess the actual magnitude of the damage. The significance here is not that a particular system or structure was damaged, but rather, that the event was of sufficient magnitude to cause this degradation.

Escalation of this emergency classification level, if appropriate, would be based on System Malfunction (S) ICs.

EAL #1 Seismic events of this magnitude can result in a VITAL AREA being subjected to forces beyond design limits, and thus damage may be assumed to have occurred to plant safety systems.

The National Earthquake Center can confirm if an earthquake has occurred in the area of the plant.

EAL #2 This EAL is based on a tornado striking (touching down) or high winds that have caused VISIBLE DAMAGE to structures containing functions or systems required for safe shutdown of the plant.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 129.2 (105 of 135)

HA6 EAL #3 This EAL addresses the effect of internal flooding caused by events such as component failures, equipment misalignment, or outage activity mishaps OR external flooding that is of such magnitude that it affects the Containment, Fuel Handling Building, Reactor Auxiliary Building or Cooling Tower Areas. It is based on the degraded performance of systems, or has created industrial safety hazards (e.g., electrical shock) that preclude necessary access to operate or monitor safety equipment. The inability to access, operate or monitor safety equipment represents an actual or substantial potential degradation of the level of safety of the plant.

Flooding as used in this EAL describes a condition where water is entering the room faster than installed equipment is capable of removal, resulting in a rise of water level within the room. Classification of this EAL should not be delayed while corrective actions are being taken to isolate the water source.

EAL #4 This EAL addresses the threat to safety related equipment imposed by PROJECTILEs generated by main turbine rotating component failures.

Therefore, this EAL is consistent with the definition of an ALERT in that the potential exists for actual or substantial potential degradation of the level of safety of the plant.

EAL #5 This EAL addresses vehicle crashes within the PROTECTED AREA that result in VISIBLE DAMAGE to VITAL AREAS or indication of damage to safety structures, systems, or components containing functions and systems required for safe shutdown of the plant.

HS1 Initiating Condition - SITE AREA EMERGENCY HOSTILE ACTION within the PROTECTED AREA.

Operating Mode Applicability: All Emergency Action Level(s):

1. A HOSTILE ACTION is occurring or has occurred within the PROTECTED AREA as reported by the Waterford 3 Security Shift Supervision.

Basis:

This condition represents an escalated threat to plant safety above that contained in the Alert in that a HOSTILE FORCE has progressed from the OWNER CONTROLLED AREA to the PROTECTED AREA.

This EAL addresses the contingency for a very rapid progression of events, such as that experienced on September 11, 2001. It is not premised solely on the potential for a radiological release. Rather the issue includes the need for rapid assistance due to the possibility for significant and indeterminate damage from additional air, land or water attack elements.

The fact that the site is under serious attack with minimal time available for further preparation or additional assistance to arrive requires Offsite Response Organization readiness and preparation for the implementation of protective measures.

This EAL addresses the potential for a very rapid progression of events due to a HOSTILE ACTION. It is not intended to address incidents that are accidental events or acts of civil disobedience, such as small aircraft impact, hunters, or physical disputes between employees within the PROTECTED AREA. Those events are adequately addressed by other EALs.

The intent of this IC is to capture those events where control of the plant cannot be reestablished in a timely manner. In this case, expeditious transfer of control of safety systems has not occurred (although fission product barrier damage may not yet be indicated).

The intent of the EAL is to establish control of important plant equipment and knowledge of important plant parameters in a timely manner. Primary emphasis should be placed on those components and instruments that supply protection for and information about safety functions such as reactivity control (ability to shutdown the reactor and maintain it shutdown), RCS inventory (ability to cool the core), and secondary heat removal (ability to maintain a heat sink).

The determination of whether or not control is established at the remote shutdown panel is based on Emergency Director judgment. The Emergency Director is expected to make a reasonable, informed judgment within 15 minutes that the plant staff has control of the plant from the remote shutdown panel.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 134.2 (110 of 135)

HG1 Initiating Condition - GENERAL EMERGENCY HOSTILE ACTION resulting in loss of physical control of the facility.

Operating Mode Applicability: All Emergency Action Level(s): (1 or 2)

1. A HOSTILE ACTION has occurred such that plant personnel are unable to operate equipment required to maintain safety functions.

OR

2. A HOSTILE ACTION has caused failure of Spent Fuel Cooling Systems and IMMINENT fuel damage is likely for a freshly off-loaded reactor core in pool.

Basis:

EAL #1:

This EAL encompasses conditions under which a HOSTILE ACTION has resulted in a loss of physical control of VITAL AREAs (containing vital equipment or controls of vital equipment) required to maintain safety functions and control of that equipment can not be transferred to and operated from another location. These safety functions are reactivity control (ability to shut down the reactor and keep it shutdown) RCS inventory (ability to cool the core), and secondary heat removal (ability to maintain a heat sink).

Loss of physical control of the Control Room or LCP-43 (remote shutdown panel) capability alone may not prevent the ability to maintain safety functions per se.

Design of the remote shutdown capability and the location of the transfer switches should be taken into account. Primary emphasis should be placed on those components and instruments that supply protection for and information about safety functions.

If control of the plant equipment necessary to maintain safety functions can be transferred to another location, then the above initiating condition is not met.

EAL #2:

This EAL addresses failure of spent fuel cooling systems as a result of HOSTILE ACTION if IMMINENT fuel damage is likely, such as when a freshly off-loaded reactor core is in the spent fuel pool. At Waterford 3, the term freshly off-loaded reactor core refers to fuel that has been discharged from the core and stored in the spent fuel pool for a period of LESS THAN one year.

HAZARDS AND OTHER CONDITIONS AFFECTING PLANT SAFETY EP-001-001 Revision 034 135.2 (111 of 135)

HG2 Initiating Condition - GENERAL EMERGENCY Other conditions exist which in the judgment of the Emergency Director warrant declaration of a General Emergency.

Operating Mode Applicability: All Emergency Action Level(s):

1. Other conditions exist which in the judgment of the Emergency Director indicate that events are in progress or have occurred which involve actual or IMMINENT substantial core degradation or melting with potential for loss of containment integrity or HOSTILE ACTION that results in an actual loss of physical control of the facility. Releases can be reasonably expected to exceed EPA Protective Action Guideline exposure levels offsite for more than the immediate site area.

Basis:

This EAL addresses unanticipated conditions not addressed explicitly elsewhere but that warrant declaration of an emergency because conditions exist which are believed by the Emergency Director to fall under the emergency classification level description for General Emergency.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after loss of all offsite AC power to safety busses.

Prolonged loss of offsite 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 to safety busses.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after an unplanned loss of > approximately 75% of the annunciators listed in the EAL or Control Room safety system indication.

This IC and its associated EAL are intended to recognize the difficulty associated with monitoring changing plant conditions without the use of a major portion of the annunciation or indication equipment.

Recognition of the availability of computer based indication equipment is considered (e.g., SPDS, plant computer, etc.).

"Planned" loss of annunciators or indicators includes scheduled maintenance and testing activities.

Emergency Action Level(s):

SYSTEM MALFUNCTION EP-001-001 Revision 034 139.2 (115 of 135)

SU6 Quantification is arbitrary, however, it is estimated that if approximately 75% of the safety system annunciators or indicators are lost, there is an increased risk that a degraded plant condition could go undetected. It is not intended that plant personnel perform a detailed count of the instrumentation lost but use the value as a judgment threshold for determining the severity of the plant conditions.

It is further recognized that most plant designs provide redundant safety system indication powered from separate uninterruptible power supplies. While failure of a large portion of annunciators is more likely than a failure of a large portion of indications, the concern is included in this EAL due to difficulty associated with assessment of plant conditions. The loss of specific, or several, safety system indicators should remain a function of that specific system or component operability status. This will be addressed by the specific Technical Specification.

The initiation of a Technical Specification imposed plant shutdown related to the instrument loss will be reported via 10 CFR 50.72. If the shutdown is not in compliance with the Technical Specification action, the Unusual Event is based on SU11 "Inability to reach required operating mode within Technical Specification limits."

Indicators associated with safety systems are those indicators for reactivity control, core cooling, maintaining reactor coolant system integrity or maintaining containment integrity.

Fifteen minutes was selected as a threshold to exclude transient or momentary power losses.

This Unusual Event will be escalated to an Alert based on a concurrent loss of compensatory indications or if a SIGNIFICANT TRANSIENT is in progress during the loss of annunciation or indication.

Operating Mode Applicability: Power Operations (Mode 1)

Startup (Mode 2)

Hot Standby (Mode 3)

Hot Shutdown (Mode 4)

Emergency Action Level(s): (1 or 2)

1.

Unidentified or pressure boundary leakage > 10 gpm OR

2.

Identified leakage > 25 gpm.

Basis:

This IC is included as an Unusual Event because it may be a precursor of more serious conditions and, as result, is considered to be a potential degradation of the level of safety of the plant. The 10 gpm value for the unidentified or pressure boundary leakage was selected as it is observable with normal Control Room indications. Lesser values must generally be determined through time-consuming surveillance tests (e.g., mass balances).

Relief valve normal operation should be excluded from this IC. However, a relief valve that operates and fails to close per design should be considered applicable to this IC if the relief valve cannot be isolated.

The EAL for identified leakage is set at a higher value due to the lesser significance of identified leakage in comparison to unidentified or pressure boundary leakage. Steam generator tube leakage is identified leakage. In either case, escalation of this IC to the Alert level is via Fission Product Barrier Degradation (F) ICs.

The purpose of this IC and its associated EALs is to recognize a loss of communications capability that either defeats the plant operations staff ability to perform routine tasks necessary for plant operations or the ability to communicate issues with offsite authorities.

The availability of one method of ordinary offsite communications is sufficient to inform federal, state, and local authorities of plant problems. This EAL is intended to be used only when extraordinary means (e.g., relaying of information from non-routine radio transmissions, individuals being sent to off-site locations, etc.) are being used to make communications possible.

Operating Mode Applicability: Hot Standby (Mode 3)

Hot Shutdown (Mode 4)

Emergency Action Level(s):

1. UNPLANNED sustained positive startup rate observed on nuclear instrumentation.

Basis:

This IC addresses inadvertent criticality events. This IC indicates a potential degradation of the level of safety of the plant, warranting an Unusual Event classification. This IC excludes inadvertent criticalities that occur during planned reactivity changes associated with reactor startups (e.g., criticality earlier than estimated).

This condition can be identified using the startup rate meter. The term sustained is used in order to allow exclusion of expected short term positive startup rates from planned control rod movements (such as shutdown bank withdrawal). These short term positive startup rates are the result of the increase in neutron population due to subcritical multiplication.

Escalation would be by the Fission Product Barrier Table (F), as appropriate to the operating mode at the time of the event.

Startup (Mode 2)

Hot Standby (Mode 3)

Hot Shutdown (Mode 4)

Emergency Action Level(s):

1. Plant is not brought to required operating mode within Technical Specifications LCO Action Statement time Basis:

Limiting Conditions of Operation (LCOs) require the plant to be brought to a required operating mode when the Technical Specification required configuration cannot be restored. Depending on the circumstances, this may or may not be an emergency or precursor to a more severe condition. In any case, the initiation of plant shutdown required by the site Technical Specifications requires a four hour report under 10 CFR 50.72 (b) Non-emergency events. The plant is within its safety envelope when being shut down within the allowable action statement time in the Technical Specifications. An immediate Unusual Event is required when the plant is not brought to the required operating mode within the allowable action statement time in the Technical Specifications. Declaration of an Unusual Event is based on the time at which the LCO-specified action statement time period elapses under the site Technical Specifications and is not related to how long a condition may have existed.

b. Any additional single power source failure will result in station blackout.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after AC power capability to safety busses has been reduced to a single power source such that any additional single failure would result in a station blackout.

The condition indicated by this IC is the degradation of the offsite and onsite AC power systems such that any additional single failure would result in a station blackout. This condition could occur due to a loss of offsite power with a concurrent failure of all but one emergency diesel generator to supply power to its safety busses. Another related condition could be the loss of all offsite power and loss of onsite emergency diesel generators with only one train of safety busses being backfed from the unit main generator, or the loss of onsite emergency diesel generators with only one train of safety busses being backfed from offsite power. The subsequent loss of this single power source would escalate the event to a Site Area Emergency in accordance with SS1.

Fifteen minutes was selected as a threshold to exclude transient or momentary losses of power.

SA3 Initiating Condition -- ALERT Automatic trip fails to shutdown the reactor and the manual actions taken from the reactor control console are successful in shutting down the reactor.

Operating Mode Applicability: Power Operations (Mode 1)

Startup (Mode 2)

Emergency Action Level(s):

1. a. An automatic trip failed to shutdown the reactor as indicated by reactor power > 5%

AND

b. Manual actions taken at the reactor control console successfully shutdown the reactor as indicated by reactor power < 5%.

Basis:

Manual trip actions taken at the reactor control console are any set of actions by the Reactor Operator(s) which causes or should cause control rods to be rapidly inserted into the core and shuts down the reactor.

This condition indicates failure of the automatic protection system to trip the reactor. This condition is more than a potential degradation of a safety system in that a front line automatic protection system did not function in response to a plant transient. Thus the plant safety has been compromised because design limits of the fuel may have been exceeded. An Alert is indicated because conditions may exist that lead to potential loss of fuel clad or RCS and because of the failure of the Reactor Protection System to automatically shutdown the plant.

Opening the A32 and B32 Bus Feeders to facilitate insertion of all CEAs requires declaration of a Site Area Emergency under SS3.

If manual actions taken at the reactor control console fail to shutdown the reactor, the event would escalate to a Site Area Emergency.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after a loss of all offsite and all onsite AC power to safety busses.

Loss of all AC power to safety busses compromises all plant safety systems requiring electric power including Shutdown Cooling, ECCS, Containment Heat Removal and the Ultimate Heat Sink. Prolonged loss of all AC power to emergency busses will lead to loss of Fuel Clad, RCS, and Containment, thus this event can escalate to a General Emergency.

Fifteen minutes was selected as a threshold to exclude transient or momentary losses of offsite power.

When temporary emergency diesels (TEDs) are used to supplement onsite AC power for safety busses in the event diesels are lost, they are credited in this EAL. The EAL condition does not apply unless the TED also failed.

SS3 Initiating Condition -- SITE AREA EMERGENCY Automatic trip fails to shutdown the reactor and manual actions taken from the reactor control console are not successful in shutting down the reactor.

Operating Mode Applicability: Power Operations (Mode 1)

Startup (Mode 2)

Emergency Action Level(s):

1. a. An automatic trip failed to shutdown the reactor AND

b. Manual actions taken at the reactor control console do not shutdown the reactor as indicated by reactor power > 5%.

Basis:

Under these conditions, the reactor is producing more heat than the maximum decay heat load for which the safety systems are designed and efforts to bring the reactor subcritical are unsuccessful. A Site Area Emergency is warranted because conditions exist that lead to IMMINENT loss or potential loss of both fuel clad and RCS.

Manual trip actions taken at the reactor control console are any set of actions by the Reactor Operator(s) which causes or should cause control rods to be rapidly inserted into the core and shuts down the reactor.

Manual trip actions are not considered successful if action away from the reactor control console is required to trip the reactor. For example, opening the A32 and B32 Bus Feeders to facilitate insertion of all CEAs requires declaration of a Site Area Emergency. This EAL is still applicable even if actions taken away from the reactor control console are successful in shutting the reactor down because the design limits of the fuel may have been exceeded or because of the gross failure of the Reactor Protection System to shutdown the plant.

Escalation of this event to a General Emergency would be due to a prolonged condition leading to an extreme challenge to either core-cooling or heat removal.

Basis:

CAUTION The Emergency Director shall make the declaration no later than 15 minutes (EAL time limit) after indication of less than 108 volts on all vital DC busses.

Loss of all DC power compromises ability to monitor and control plant safety functions. Prolonged loss of all DC power will cause core uncovering and loss of containment integrity when there is significant decay heat and sensible heat in the reactor system.

Fifteen minutes was selected as a threshold to exclude transient or momentary power losses.

SYSTEM MALFUNCTION EP-001-001 Revision 034 155.2 (131 of 135)

SS6 "Planned" and UNPLANNED actions are not differentiated since the loss of instrumentation of this magnitude is of such significance during a transient that the cause of the loss is not an ameliorating factor.

Quantification is arbitrary, however, it is estimated that if approximately 75% of the safety system annunciators or indicators are lost, there is an increased risk that a degraded plant condition could go undetected. It is not intended that plant personnel perform a detailed count of the instrumentation lost but use the value as a judgment threshold for determining the severity of the plant conditions. It is also not intended that the Shift Manager be tasked with making a judgment decision as to whether additional personnel are required to provide increased monitoring of system operation.

A Site Area Emergency is considered to exist if the Control Room staff cannot monitor safety functions needed for protection of the public while a significant transient is in progress.

Site specific indications needed to monitor safety functions necessary for protection of the public must include Control Room indications, computer generated indications and dedicated annunciation capability.

Indicators associated with safety systems are those indicators for reactivity control, core cooling, maintaining reactor coolant system integrity or maintaining containment integrity.

"Compensatory indications" in this context includes computer based information such as SPDS, QSPDS, COLSS, etc. This should include all computer systems available for this use depending on specific plant design and subsequent retrofits.

CAUTION If making the declaration based on the restoration of at least one safety bus, then the Emergency Director shall make the declaration no later than 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months (EAL time limit) after the loss of all offsite and onsite AC power to safety busses.

Loss of all AC power to safety busses compromises all plant safety systems requiring electric power including Shutdown Cooling, ECCS, Containment Heat Removal and the Ultimate Heat Sink. Prolonged loss of all AC power to safety busses will lead to loss of fuel clad, RCS, and containment, thus warranting declaration of a General Emergency.

This IC is specified to assure that in the unlikely event of a prolonged station blackout, timely recognition of the seriousness of the event occurs and that declaration of a General Emergency occurs as early as is appropriate, based on a reasonable assessment of the event trajectory.

SYSTEM MALFUNCTION EP-001-001 Revision 034 158.2 (134 of 135)

SG1 The likelihood of restoring at least one safety bus should be based on a realistic appraisal of the situation since a delay in an upgrade decision based on only a chance of mitigating the event could result in a loss of valuable time in preparing and implementing public protective actions.

When temporary emergency diesels (TEDs) are used to supplement onsite AC power for safety busses in the event diesels are lost, they are credited in this EAL.

In addition, under these conditions, fission product barrier monitoring capability may be degraded.

Although it may be difficult to predict when power can be restored, it is necessary to give the Emergency Director a reasonable idea of how quickly (s)he may need to declare a General Emergency based on two major considerations:

1. Are there any present indications that core cooling is already degraded to the point that loss or potential loss of Fission Product Barriers is IMMINENT?

2. If there are no present indications of such core cooling degradation, how likely is it that power can be restored in time to assure that a loss of two barriers with a potential loss of the third barrier can be prevented?

Thus, indication of continuing core cooling degradation must be based on Fission Product Barrier monitoring with particular emphasis on Emergency Director judgment as it relates to IMMINENT loss or potential loss of fission product barriers and degraded ability to monitor fission product barriers.

SYSTEM MALFUNCTION EP-001-001 Revision 034 159 (LAST PAGE).2 (135 of 135)

SG3 Initiating Condition -- GENERAL EMERGENCY Automatic trip and all manual actions fail to shutdown the reactor and indication of an extreme challenge to the ability to cool the core exists.

Operating Mode Applicability: Power Operations (Mode 1)

Startup (Mode 2)

Emergency Action Level(s):

Basis:

Under these conditions, the reactor is producing more heat than the maximum decay heat load for which the safety systems are designed and efforts to bring the reactor subcritical are unsuccessful.

In the event either of these challenges exists at a time that the reactor has not been brought below the power associated with the safety system design a core melt sequence exists. In this situation, core degradation can occur rapidly. For this reason, the General Emergency declaration is intended to be anticipatory of the fission product barrier table declaration to permit maximum off-site intervention time.

1. a. An automatic trip failed to shutdown the reactor AND

b. All manual actions do not shutdown the reactor as indicated by reactor power > 5%

AND

c. Either of the following exist or have occurred due to continued power generation:

CET temperatures at or approaching 1200° F OR Inability to maintain at least one steam generator level > 36.3% wide range.
