Background:

Emergency Classification Table 3-1 (Revision 34 of the Emergency Plan)was reviewed to identify sections where the descriptive instruction to licensed operators and Plant management could be improved.Specifically, the review addressed areas where clarification could be provided to emergency action levels without changing the intent of the classification criteria.Regulatory guidance and industry standards have been consulted as part of this review.The following changes are proposed: Event/Class E Plan Rev.34 Current E Plan Rev.DRAFT Pro osed Reason for Chan e 1.A Abnormal Primaiy Leak No CAUTION statement Rate CAUTION: THIS SECTION SHOULD NOT BE USED FOR STEAM GENERATOR TUBE LEAK/RUPTURE.

Clarify difference between classification criteria for primary/secondary leakage.UNUSUAL EVENT 2.Indication of leaking RCS safety or relief valve which causes RCS pressure to drop below~1600 sia.UNUSUAL EVENT 2.Indication of leaking RCS safety or relief valve which causes RCS pressure to drop below: Unit 1-1600 sia Unit 2-1736 sla Relief valve settings different for Units 1 and 2.ALERT 1.Charging/letdown mismatch or measured RCS leakage indicates greater than 50 gpm but less than 132 gpm.ALERT 1.Charging/letdown mismatch or measured RCS leakage indicates greater than 50 gpm but less than available char in ca gelt.Current section does not recognize loss of charging capacity and conflicts with Site Area Emergency section.

Event/Class 1.A Abnormal Primary Leak Rate (continued) 1.B Abnormal Primary to Secondary Leak Rate E Plan Rev.34 Current SITE AREA EMERGENCY 1.RCS leakage greater than 132 gpm occurring with RCS pressure above HPSI shutoffhead.

OR 2.RCS leakage greater than available makeup occurring with RCS pressure below HPSI shutoff head.OR 3.Loss of RCS subcooled margin due to RCS leakage (saturated conditions).

OR 4.Containment High Range Radiation Monitors indicate 7.3 x 10'/hr (if CHRRM inoperable, Post-LOCA monitors indicate between 100 and 1000 mR/hr).SITE AREA EMERGENCY Ra id failure of steam enerator tube s GREATER THAN char in um ca aci with steamrelease in ro ress E Plan, Rev.DRAFT Pro osed SITE AREA EMERGENCY 1.RCS leakage greater than 50 gpm and greater than available charging capacity.OR 2.Loss of RCS subcooled margin due to RCS leakage (saturated conditions).

SITE AREA EMERGENCY Ra idfailureofsteam eneratortube s GREATER THAN char in um ca acit withsteamreleasein ro ress Reason for Chan e Current revision does not recognize loss of charging capability in some cases where leakage is less than 132 gpm.Current revision does not clarify credit for normal makeup (charging) only or any makeup.~Proposed revision provides for clear classification criteria for LOCA greater than 50 gpm and greater than (normal)charging capacity, which is consistent with NUREG guidance and industry examples.Criteria for radiation monitor readings are identified in Event/Class 2.A (Uncontrolled Effluent Release).Current revision caused confusion to users, specifically concerning"unisolable status of slight release potential from equipment (such as steam driven AFW).3.Secondary steam release in progress from affected generator (i.e., ADVs, Steam Safety(s), or Unisolable.)

3.Secondary steam release in progress fromaffecled generatorieeAADDVVas stuck steam safe s unisolable

~leak Proposed revision provides additional clarification to user on types of secondary steam releases to be considered when classifying event.

Event/Class 2.A Uncontrolled Effluent Release 3.Fire Explosion E Plan Rev.34 Current SITE AREA EMERGENCY 2.Measured Dose Rates or Offsite Dose Calculation (EPIP-09)worksheet values at one mile in excess of: A.50 mrem/hr (total dose TEDE)or 250 mrem/hr (thyroid dose CDE)for~/i hour.OR B.500 mrem/hr (total dose TEDE)or 2500 mrem/hr (thyroid dose CDE)for two minutes at one mile.UNUSUAL EVENT Uncontrolled fire within the plant lasting more than 10 minutes.No NOTE in section.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY 2.Measured Dose Rates or Offsite Dose Calculation (EPIP-09)worksheet values at one mile in excess of: A.50 mrem/hr (total dose~rate or 250 mrem/hr (thyroid dose~rate for/g hour.OR B.500 mrem/hr (total dose~rate or 2500 mrem/hr (thyroid dose~rate for two minutes at one mile.UNUSUAL EVENT Uncontrolled fire within the gower block lasting more than 10 minutes.NOTE: EXPLOSION IS DEFINED AS A RAPID CHEMICAL REACTION RESULTING IN NOISE HEAT AND THE RAPID EXPANSION OF GAS.Reason for Chan e Confusion by users on dose rates versus total dose.Proposed revision provides clear criteria based on dose rate.Use of"power block provides clear description of structures of equipment that should be considered in this classification."Power block" is specifically defined in EPIP-01.NOTE provides clear definition of explosion event.

Event/Class E Plan Rev.34 Current 3.Explosion (continued)

ALERT SITE AREA EMERGENCY Severe damage to safe shutdown equipment from explosion.

Damage to facility by explosion which affects plant operation.

E Plan Rev.DRAFT Pro osed ALERT Damage to structures/com onents within the Protected Area by explosion which affects plant operation.

SITE AREA EMERGENCY Severe damage to safe shutdown equipment from explosion Ji.e.both trains rendered ino erable.Reason for Chan e Proposed revision provides clear identification of the location (Protected Area)where consideration for ciassiTieation of explosions occur.Proposed revision provides clear criteria for the meaning of severe damage to safe shutdown equipment, which applies regulatory guidance definition for loss of equipment functions.

4.B Fuel Handling Accident SITE AREA EMERGENCY Major damage to irradiated fuel in Containment or Fuel Handling Building 1.Step increase in the reading of radiation monitors in the plant vent and/or in the Fuel Handling Building AND 2.Damage to more than one irradiated fuel assembly.OR 3.Uncovering of one or more irradiated fuel assemblies in the Spent Fuel Pool.SITE AREA EMERGENCY Major damage to irradiated fuel in Containment or Fuel Handling Building 1.Affected area radiation monitor levels reater than 1000 mr/hr.AND~2.Ma or Damage to one or more irradiated fuel assemblies OR 3.Ma or dama e resultin from uncovering of one or more irradiated fuel assemblies in the Spent Fuel Pool Current revision does not provide specific radiation dose rate threshold.

Current revision criteria requires knowledge of extent of damage ("more than one irradiated fuel assembly")which will likely not be known.Proposed revision provides specific radiation dose rate threshold (consistent with other classification criteria)and does not limit classification based on unknown extent of damage.

Event/Class 5.A Earthquake E Plan Rev.34 Current UNUSUAL EVENT 2.An earthquake is detected by plant seismic monitor instruments.

ALERT A confirmed earthquake occurs which registers GREATER THAN 0.05 g.E Plan Rev.DRAFT Pro osed UNUSUAL EVENT 2.An earthquake is detected by plant seismic monitor instruments or other means.ALERT A confirmed earth uake has occurred 1.A confirmed earthquake occurs which registers GREATER THAN 0.05 g within the Owner Controlled Area.OR 2.A confirmed earth uake has occurred that could cause or has caused a tri of the turbine enerator or reactor.Reason for Chan e Current classification does not provide for classification based on information received by other (non-plant) seismic monitors, such as from other nuclear sites, colleges, or scientific monitoring equipment.

The current revision does not consistently identify the location of the increased seismic activity (within the Owner Controlled Area, as in UNUSUAL EVENT).The proposed revision relates the measurement of seismic activity to the Owner Controlled Area and provides for direct indications for effects of the earthquake on plant conditions (turbine or reactor trip).

Class/Event 5.A Earthquake (continued)

E Plan Rev.34 Current SITE AREA EMERGENCY A confirmed earthquake occurs which registers GREATER THAN 0.1 g.with plant not in cold shutdown.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY A confirmed earth uake has occurred 1.A confirmed earth uake occurs which re isters GREATER THAM 0.1.within the Owner Controlled Area and the lant is not in cold shutdown.OR Reason for Chan e The current revision does not consistently identify the location of the increased seismic activity (within the Owner Controlled Area, as in UNUSUAL EVENT).The proposed revision relates the measurement of seismic activity to the Owner Controlled Area and provides for direct indications for effects of the earthquake on plant conditions (loss of safety related functions).

2.A confirmed earth uake has occurred that has caused loss of an safet related s stem function i.e.both 5.C Tornado ALERT Any tornado striking facility.ALERT Any tomario striking~the ower block.The current revision did not identify specific affected areas of the plant to be considered for a tornado strike.Use of"power block" provides clear description of structures of equipment that should be considered in this classification.

'Power block" is specifically defined in EPIP-01.

Event/Class 6.A Increased Awareness or Potential Core Melt E Plan Rev.34 Current ALERT Emergency Coordinator's judgement that plant conditions exist which warrant: 1.Increased awareness and activation of Emergency Response personnel.

E Plan Rev.DRAFT Current ALERT Emergency Coordinator's judgement that plant conditions exist which have a otential to de rade the level of safet at the plant.Reason for Chan e The current revision causes confusion to whether use of emergency response facilities or activation of any emergency response personnel in its self justifies ALERT classification.

Proposed revision makes judgement criteria clear that degradation of plant conditions justify classification of an ALERT.1.Emergency Coordinator's judgement that plant conditions exist which are si nificantl uncontrollable manner.1.Activation of emergency response facilities and monitoring teams or a precautionary notification of the public near the site.SITE AREA EMERGENCY SITE AREA EMERGENCY Emergency Coordinator's judgement that plant conditions exist which warrant: The current revision causes confusion to whether use of emergency response facilities in~ifs self ustifies SITE AREA EMERGENCY classification.(Classification of SITE AREA EMERGENCY always results in notification of the public.)Proposed revision makes judgement criteria clear that degradation of plant conditions justify classification of a SITE AREAEMERGENCY.

GENERALEMERGENCY 2.LOCA with initially successful ECCS and subsequent failure of containment hear removal systems for several hours.GENERAL EMERGENCY 2.LOCA with initially successful ECCS and subsequent failure of containment heat removal hours.Current revision does not contain specific time criteria in classification considerations.

Proposed revision provides specific time span, after which a GENERALEMERGENCY classification is warranted.

Event/Class 6.A Increased Awareness or Potential Core Melt (continued)

E Plan, Rev.34 Current GENERAL EMERGENCY 4.Failure of off-site and on-site power along with loss of emergency feedwater makeup capability for several hours.E Plan, Rev.DRAFT Pro osed GENERALEMERGENCY 4.Failure of off-site and on-site power along with loss of ave:gemy feedwater makeup capability for P-" Reason for Chan e The current revision causes confusion with user in regard to what is"emergency feedwater".

The plant does not designate any equipment as'emergency feedwater.

Current revision does not contain specific time criteria in classification considerations.

The proposed revision provides clear indication that if there is no feedwater for'greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, then a GENERAL EMERGENCY classification is warranted.

7.A Loss of Power ALERT 2.Failure of both emergency diesel generators to start or synchronize.

SITE AREA EMERGENCY 2.Sustained failure of both emergency diesel generators to start or synchronize.

ALERT 2.Failure of both emergency diesel generators to start or load.SITE AREA EMERGENCY 2.Sustained failure of both emergency diesel generators to start or load.Current revision does not address ability of diesel generator to perform its intended function (load t onto emergency buses)Proposed revision provides clear indication that if the diesel is not loaded, then classification is warranted.

Event/Class 8.8 Loss of Alarms/Communication/

Monitoring 9.A Aircraft/Missile E Plan, Rev.34 Current UNUSUAL EVENT 3.Unplanned loss of most or all Safety System annunciators for greater than 15 minutes.SITE AREA EMERGENCY 1.Inability to monitor a significant transient in progress.ALERT 1.Aircraft crash in the Owner Controlle'd Area damaging plant structures.

E Plan, Rev.DRAFT Current UNUSUAL EVENT 1.Unplanned loss of most ig rester~than 75%or alt Safety System annunciators for greater than 15 minutes.SITE AREA EMERGENCY 1.Inability to~effecttvet monitor a significant transient in progress.NOTE: Si nificant transient exam les include: reactor tri turbine runback reater than 25%and thermal oscillations reater than 10%.ALERT 1.Aircraft crash in the ower block.Reason for Chan e Current revision does not provide for a quantitative value for loss of"most'nnunciators.

Proposed revision indicates a specific percentage of annunciators lost needed to classify an UNUSUAL~EVENT.Current revision does not provide guidance on degree of ability in which a transient can be monitored in classifying the event.Current revision does not provide definition of significant transient.

Proposed revision provides additional guidance for the user to determine that, if a transient can not be effectively monitored, then a SITE AREA EMERGENCY is warranted.

Additionally, examples of significant transients are provided.Current revision does not provide reference to crash or missile impact to specific plant structures.

OR 2.Visual or audible indication of missile impact on plant structures.

OR 2.Visual or audible indication of Proposed revision provides clear indication (i.e., the power block)where a crash or missile impact would warrant classification of ALERT.

Event/Class 9.A Aircraft/Missile (continued)

E Plan Rev.34 Current SITE AREA EMERGENCY 1.Aircraft crash in the Owner Controlled Area damaging vital plant systems.OR 2.Damage to safe shutdown equipment from any missile.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY 1.Aircrah crash~in the ower block damaging vital plant systems.OR 2.Damage resultin in loss of safe shutdown equipment from any missile.Reason for Chan e Current revision does not provide reference to crash or missile impact on specific plant structures.

Proposed revision defines specific area of the plant where damage is considered classifiable.

Proposed revision identifies effect on safe shutdown equipment as criteria for determining classification of SITE AREA EMERGENCY.

Use of"power block" provides clear description of structures of equipment that should be considered in this classification."Power block" is specifically defined in procedure.

9.C Toxic or Flammable Gas SITE AREA EMERGENCY Toxic or flammable gas has diffused into vital areas affecting access to or the operation of safe shutdown equipment.

SITE AREA EMERGENCY Toxic or flammable gas has diffused into vital areas compromising the function of safety related equipment (i.e., both trains rendered inoperable)

Current revision caused confusion with user differentiating between ALERT and SITE AREA EMERGENCY.

Current revision does not consistently relate loss of safety system function with other classification criteria.Proposed revision provides clear difference between ALERT and SITE AREA EMERGENCY.

Attachment 1 Explanation of Proposed Changes to St.Lucie Radiological Emergency Plan Table 3-1;Emergency Classification Table

Background:

Emergency Classification Table 3-1 (Revision 34 of the Emergency Plan)was reviewed to identify sections where the descriptive

, instruction to licensed operators and Plant management could be improved.SpeciTically, the review addressed areas where clarification could be provided to emergency action levels without changing the intent of the classiTication criteria.Regulatory guidance and industry standards have been consulted as part of this review.The following changes are proposed: Event/Class E Plan Rev.34 Current EPlan Rev.DRAFT Pro osed ReasonforChan e 1.A Abnormal Primary Leak Rate No CAUTION statement UNUSUAL EVENT 2.Indication of leaking RCS safety or relief valve which causes RCS pressure to drop below~1600 ele.CAUTION: THIS SECTION SHOULD NOT BE USED FOR STEAM GENERATOR TUBE LEAK/RUPTURE.

UNUSUAL EVENT 2.Indication of leaking RCS safety or relief valve which causes RCS pressure to drop below: Unit 1-1600 sia Unit 2-1736 sia Clarify difference between classification criteria for primary/secondary leakage.Relief valve settings different for Units 1 and 2.ALERT.1.Charging/letdown mismatch or measured RCS leakage indicates greater than 50 gpm but less than 132 gpm.ALERT 1.Charging/letdown mismatch or measured RCS leakage indicates greater than 50 gpm but less than available char in ca aci Current section does not recognize loss of charging capacity and conflicts with Site Area Emergency section.

Event/Class E Plan, Rev.34 Current E Plan, Rev.DRAFT Pro osed 1.A Abnormal Primary Leak Rate (continued) 1.8 Abnormal Primary to Secondary Leak Rate SITE AREA EMERGENCY 1.RCS leakage greater than 132 gpm occurring with RCS pressure above HPSI shutoff head.OR 2.RCS leakage greater than available makeup occurring with RCS pressure below HPSI shutoff head.OR 3.Loss of RCS subcooled margin due to RCS leakage (saturated conditions).

OR 4.Containment High Range Radiation Monitors indicate 7.3 x 10'/hr (if CHRRM inoperable, Post-LOCA monitors indicate.between 100 and 1000 mR/hr).SITE AREA EMERGENCY Ra id failure of steam enerator tube s GREATERTHAN char in um ca aci with steam release in ro ress 3.Secondary steam release in progress from affected generator (i.e., ADVs, Steam Safety(s), or Unisoiable.)

SITE AREA EMERGENCY Ra ldfailureofsteam eneratortube s GREATER THAN char in um ca aci with steam release in ro ress 3.Secondary steam release in progress from affed ed generator~e..ADVs stuck steam safe s unlsolable

~leak Current revision does not recognize loss of charging capability in some cases where leakage is less than 132 gpm.Current revision does not ctadfy credit for normal makeup (charging) only or any makeup.Proposed revision provides for clear classification criteria for LOCA greater than 50 gpm and greater than (normal)charging capacity, which is consistent with NUREG guidance and industry examples.Criteria for radiation monitor readings are identified in-Event/Class 2.A (Uncontrolled Effluent Release).Current revision caused confusion to users, specifically concerning"unisolable status of slight-release potential from equipment (such as steam driven AFW).Proposed revision provides additional clarification to user on types of secondary steam releases to be considered when classifying event.

Event/Class 2.A Uncontrolled Effluent Release.3.Fire E Plan Rev.34 Current SITE AREA EMERGENCY 2.Measured Dose Rates or Offsite Dose Calculation (EPIP-09)worksheet values at one mile in excess of: A.50mrem/hr(totaldose TEDE)or250 mrem/hr (thyroid dose CDE)for I*hour.OR B.500 mrem/hr (total dose TEDE)or 2500 mrem/hr (thyroid dose CDE)for two minutes at one mile.UNUSUAL EVENT Uncontrolled fire within the plant lasting more than 10 minutes.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY 2.Measured Dose Rates or Offsite Dose Calculation (EPIP-09)worksheet values at one mile in excess of: A.50 mrem/hr (total dose~rate or 250 mrem/hr (thyroid dose~rate for/~hour.OR B.500 mrem/hr (total dose~rate or 2500 mrem/hr (thyroid dose~rate for two minutes at one mile.UNUSUAL EVENT Uncontrolled fire within the power block lasting more than 10 minutes.Reason for Chan e Confusion by users on dose rates versus total dose.Proposed revision provides clear criteria based on dose rate.Use of"power block provides clear description of structures of equipment that should be considered in this classification.

Power block" is specifically defined in EPIP-01.Explosion No NOTE in section.NOTE'XPLOSION IS DEFINED AS A RAPID CHEMICAL REACTION RESULTING IN NOISE HEAT AND THE RAPID EXPANSION OF GAS.NOTE provides clear definition of explosion event.

Event/Class E Plan Rev.34 Current E Plan Rev.DRAFT Pro osed Reason for Chan e 3.Explosion (continued)

ALERT Damage to facility by explosion which affects plant operation.

SITE AREA EMERGENCY Severe damage to safe shutdown equipment from explosion.

ALERT Damage to structures/com onents within the Protected Area by explosion which affects plant operation.

SITE AREA EMERGENCY Severe damage to safe shutdown equipment from explosion~i.e.both trains rendered ino erable.Proposed revision provides clear identification of the location (Protected Area)where consideration for classification of explosions occur.Proposed revision provides clear criteria for the meaning of severe damage to safe shutdown equipment, which applies regulatory guidance definition for loss of equipment functions.

4.B Fuel Handling Accident SITE AREA EMERGENCY Major damage to irradiated fuel in Containment or Fuel Handling Building 1.Step increase in the reading of radiation monitors in the plant vent and/or in the Fuel Handling Building AND 2.Damage to more than one irradiated fuel assembly.OR 3.Uncovering of one or more irradiated fuel assemblies in the Spent Fuel Pool.SITE AREA EMERGENCY Major damage to irradiated fuel in Containment or Fuel Handling Building Affected area radiation monitor levels reater than 1000 mr/hr.AND~2.Ma or Damage to one or more irradiated fuel assemblies OR 3.Ma or dama e resultin from uncovering of one or more irradiated fuel assemblies in the Spent Fuel Pool Current revision does not provide specific radiation dose rate threshold.

Current revisiori criteria requires knowledge of extent of damage ("more than one irradiated fuel assembly")which will likely not be known.Proposed revision provides specific radiation dose rate threshold (consistent with other classification criteria)and does not limit classification based on unknown extent of damage.

Event/Class 5.A Earthquake E Plan Rev.34 Current UNUSUAL EVENT 2.An earthquake is detected by plant seismic monitor instruments.

ALERT A confirmed earthquake occurs which registers GREATER THAN 0.05 g.E Plan Rev.DRAFT Pro osed UNUSUAL EVENT 2 An earthquake is detected by plant seismic monitor instruments or other means.ALERT A confirmed earth uake has occurred 1.A confirmed earthquake occurs which registers GREATER THAN 0.05 g within the Owner Controlled Area.OR 2.A confirmed earth uake has occurred that could cause or has caused a tri of the turbine enerator or reactor.Reason for Chan e Current classification does not provide for classification based on information received by other (non-plant) seismic monitors, such as from other nuclear sites, colleges, or scientiTic monitoring equipment.

The current revision does not consistently identify the location of the increased seismic activity (within the Owner Controlled Area, as in UNUSUAL EVENT).The proposed revision relates the measurement of seismic activity to the Owner Controlled Area and provides for direct indications for effects of the earthquake on plant conditions (turbine or reactor trip).

Class/Event 5.A Earthquake (continued)

E Plan Rev.34 Current SITE AREA EMERGENCY A confirmed earthquake occurs which registers GREATER THAN 0.1 g.with plant not in cold shutdown.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY A confirmed earth uake has occurred 1.A confirmed earth uake occurs which re isters GREATER THAN 0.1.within the Owner Controlled Area and the lant is not in cold shutdown.OR Reason for Chan e The current revision does not consistently identify the location of the increased seismic activity (within the Owner Controlled Area, as in UNUSUAL EVENT).The proposed revision relates the measurement of seismic activity to the Owner Controlled Area and provides for direct indications for effects of the earthquake on plant conditions (loss of safety related functions).

2.A confirmed earth uake has occurred that has caused loss of an safet related s stem function i.e.both 5.C Tornado ALERT Any tornado striking facility.ALERT, Any tomedo striking tahe ower block.The current revision did not identify specific affected areas of the plant to be considered for a tornado strike.Use of"power block" provides clear description of structures of equipment that should be considered in this classification.

Power block is specifically defined in EPIP-01.

Event/Class 6.A Increased Awareness or Potential Core Melt E Plan Rev.34 Current ALERT Emergency Coordinator's judgement that plant conditions exist which warrant: 1.Increased awareness and activation of Emergency Response personnel.

E Plan Rev.DRAFT Current ALERT Emergency Coordinator's judgement that plant conditions exist which have a otential to de rade the level of safe at the plant.Reason for Chan e The current revision causes confusion to whether use of emergency response facilities or activation of any emergency response personnel in its self justifies ALERT classification.

Proposed revision makes judgement criteria clear that degradation of plant conditions justify classification of an ALERT.SITE AREA EMERGENCY Emergency Coordinator's judgement that plant conditions exist which warrant: 1.Activation of emergency response facilities and monitoring teams or a precautionary notification of the public near the site.SITE AREA EMERGENCY 1.Emergency Coordinator's judgement that plant conditions uncontrollable manner.The current revision causes confusion to whether use of emergency response facilities in its se)f justifies SITE AREA EMERGENCY classification.(Classification of SITE AREA EMERGENCY always results in notification of the public.)Proposed revision makes judgement criteria clear that degradation of plant conditions justify classification of a SITE AREAEMERGENCY.

GENERAL EMERGENCY 2.LOCA with initially successful ECCS and subsequent failure of containment hear removal systems for several hours.GENERALEMERGENCY 2.LOCA with initially successful ECCS and subsequent failure of containment heat removal hours.Current revision does not contain specific time criteria in classification considerations.

Proposed revision provides specific time span, after which a GENERAL EMERGENCY classification is warranted.

Event/Class 6.A Increased Awareness or Potential Core Melt (continued)

E Plan, Rev.34 Current GENERAL EMERGENCY 4.Failure of off-site and on-site power along with loss of emergency feedwater makeup capability for several hours.E Plan, Rev.DRAFT Pro osed GENERALEMERGENCY 4.Failure of off-site and on-site power along with loss of emergency feedwater makeup capability for 8-'""'Reason for Chan e The current revision causes confusion with user in regard to what is"emergency feedwater".

The plant does not designate any equipment as'emergency feedwater.

Current revision does not contain specific time criteria in classification considerations.

The proposed revision provides clear indication that if there is no feedwater for greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, then a GENERAL EMERGENCY cIassification is warranted.

7.A Loss of Power ALERT 2.Failure of both emergency diesel generators to start or synchronize.

SITE AREA EMERGENCY 2.Sustained failure of both emergency diesel generators to start or synchronize.

ALERT 2.Failure of both emergency diesel generators to start or load.SITE AREA EMERGENCY 2.Sustained failure of both emergency diesel generators to start or load.Current revision does not address ability of diesel generator to perform its intended function (load onto emergency buses)Proposed revision provides clear indication that if the diesel is not loaded, then classification is warranted.

Event/Class 8.8 Loss of Alarms/Communication/

Monitoring 9.A Aircraft/Missile E Plan, Rev.34 Current UNUSUAL EVENT 3.Unplanned loss of most or all Safety System annunciators for greater than 15 minutes.SITE AREA EMERGENCY 1.Inability to monitor a significant transient in progress.ALERT 1.Aircraft crash in the Owner Controlled Area damaging plant structures.

OR 2.Visual or audible indication of missile impact on plant structures.

E Plan Rev.DRAFT Current UNUSUALEVENT 1.Unplanned lossofmostigreater t~han 75%or atl Safety System annunciators for greater than 15 minutes.SITE AREA EMERGENCY 1.Inability to e~ffeottvet monitor a significant transient in progress.NOTE: Si nificant transient exam les include: reactor tri turbine runback reater than 25%and thermal oscillations reater than 10%.ALERT block.OR 2.Visual or audible indication of Reason for Chan e Current revision does not provide for a quantitative value for loss of"most annunciators.

Proposed revision indicates a specific percentage of annunciators lost needed to classify an UNUSUAL EVENT.Current revision does not provide guidance on degree of ability in which a transient can be monitored in classifying the event.Current revision does not provide definition of significant transient.

Proposed revision provides additional guidance for the user to determine that, if a transient can not be effectively monitored, then a SITE AREA EMERGENCY is warranted.

Additionally, examples of significant transients are provided.Current revision does not provide reference to crash or missile impact to specific plant structures.

Proposed revision provides clear indication (i.e., the power block)where a crash or missile impact would warrant classificatio of ALERT.

Event/Class 9.A Aircraft/Missile (continued)

E Plan Rev.34 Current SITE AREA EMERGENCY 1.Aircraft crash in the Owner Controlled Area damaging vital plant systems.OR 2.Damage to safe shutdown equipment from any missile.E Plan Rev.DRAFT Pro osed SITE AREA EMERGENCY 1.Aircraft crash~to the ower block damaging vital plant systems.OR 2.Damage resultin in loss of safe shutdown equipment from any missile.Reason for Chan e Current revision does not provide reference to crash or missile impact on specific plant structures.

Proposed revision defines specific area of the plant where damage is considered classifiable.

Proposed revision identifies effect on safe shutdown equipment as criteria for determining classification of SITE AREA EMERGENCY.

Use of power block provides clear description of structures of equipment that should be considered in this classification."Power block is specifically defined in procedure.

9.C Toxic or Flammable Gas SITE AREA EMERGENCY Toxic or flammable gas has diffused into vital areas affecting access to or the operation of safe shutdown equipment.

SITE AREA EMERGENCY Toxic or flammable gas has diffused into vital areas compromising the function of safety related equipment (i.e., both trains rendered inoperable)

Current revision caused confusion with user differentiating between ALERT and SITE AREA EMERGENCY.

Current revision does not consistently relate loss of safety system function with other classification criteria.Proposed revision provides clear difference between ALERT and SITE AREA EMERGENCY.
