1 | Company's PowerYankee (MYAPC) plan This document to for responding describes the Maine emergencies that may ariseAtomic Yankee at the Maine Independent Spent Fuel Storage Installation (ISFSI). The overall purpose of the plan is to delineate the actions necessary to safeguard ISFSI personnel and minimize damage to site property in the event of an incident at the ISFSI. Analyses of the possible design basis events and consequences are presented in the Safety Analysis Report for the UMS Universal Storage System (NAC UMS SAR) used at the ISFSI for dry spent fuiel storage. | ||
The analyses of the potential radiological impact of an accident at the Maine Yankee site indicates that any releases beyond the ISESI Controlled Area boundary are expected to be less than the U.S. Environmental Protection Agency (EPA) protective action guide (PAG) exposure levels, as detailed in EPA-400-R-92-001, Manual of Protective Action Guides and Protective Actions for Nuclear Incidents. Exposure levels which may warrant pre-planned response measures are generally limited to the Controlled Area. For this reason, radiological emergency planning is focused on the Controlled Area. | |||
1.1 REV 7 | |||
2.0 FACILITY DESCRIPTION 2.1 Maine Yankee Site 2.1.1 Overview The Maine Yankee site is located in the town of Wiscasset, Lincoln County, Maine. Site coordinates are approximately 43 degrees 57 minutes 5 seconds north latitude and 69 degrees 41 minutes 45 seconds west longitude. The site is bounded by the Back River on the east, mainland on the north and Bailey Cove on the west. The ISFSI is located on a peninsula known as Bailey Point, which extends south to Montsweag Bay (Figure 2-1). | |||
The ISFSI facility is depicted on Figure 2-2. Spent nuclear fuel is in interim storage within the specified secure fuel storage area and will be monitored by the ISFSJ staff. | |||
2.2 General Area Within 5 miles of the site, land use is largely rural residential, small businesses, summer houses, idle farmland and forest. Housing is scattered along principal roads and is concentrated only in the center of Wiscasset. | |||
The waters of the Back River, Montsweag Bay and associated tributaries are tidal and open to boating, both commercial and recreational. Regulation of boating is the responsibility of the U.S. Coast Guard and the State of Maine. The primary type of boating in the Mon._tswe~ag B~ay - Back River is shallow draft Pleasure boats. With no commercial traffic in the area, there is essentially no hazard to the site from potential accidents with commercial barges or boats carrying hazardous, toxic or explosive materials. | |||
Industrial activity within the general area of the JSFSJ is minimal. The largest industrial facility is the Bath Iron Works, a shipbuilding facility located on the Kennebec River approximately 7 miles southwest in the city of Bath. | |||
The Wiscasset Municipal Airport is the nearest airport to the site and is located approximately one .mile northwest of the site. It consists of one runway (approximately 3,400 feet long by 75 feet wide). This runway is aligned such that takeoffs and landings are on headings of either 070 or 250 (the predominant heading is 250). The majorities of aircraft that are serviced by this facility are privately owned and are similar to the Piper Colt, Cherokee, and Cessna 150 and 172 type craft. The largest aircraftthat typically use the facility are similar to the Lear 25, Citation II and Rockwell Commander type craft. | |||
2.1 REV 7 | |||
2.3 Independent Spent Fuel Storage Installation (ISFSI) | |||
The ISFSI is designed for interim storage of fuel for a minimum of 50 years in a contained shielded system. The ISFSI utilizes the Universal MPC System (UMSTM) developed by NAC International. The UMSTM is a canister-based multi-purpose canister (MPG) system designed for both storage and transportation of spent nuclear fuel. The canister-based spent fuel storage system is a passive system which utilizes an outer concrete cylinder called a Vertical Concrete Cask (VCC) to protect and shield the inner sealed metal canister. The VCC is vented for natural convection cooling and has no moving parts. Decay heat from the loaded fuel storage canister in the VCC is dissipated to the surrounding air by a once through buoyancy driven airflow. The VCC provides radiation shielding, as well as protection from tornado missiles and earthquakes. | |||
The ISFST site consists of a Protected Area (PA) for fuel storage and a Security/Operations Building. The ISFSI has a Controlled Area that extends at least 300 meters from the nuclear fuel storage area. | |||
The PA has sixteen concrete storage pads, and is surrounded by a security fence and a nuisance fence with an isolation zone between the two fences. A partial earthen berm is provided around the facility to reduce the visual impact of the facility. The ISFSI contains a total of 64 storage casks, with one sealed fuel canister per VCC. The types of canisters stored in the storage casks include 60 casks for spent fuel and 4 casks for Greater Than Class C (GTCC) waste. Sixteen storage pads of equal size are provided for uniformity, which allows for storage of 4 casks per storage pad. The ISFSI site is arranged to provide maneuvering room around the storage pads for access with a cask heavy haul tractor-trailer. | |||
The Security/Operations Building provides offices and work space for the operating and maintenance personnel, including the Radiation Controls Checkpoint lunch/conference rooms, restrooms, locker rooms, document control room, spare parts storage, and a diesel generator for emergency power. The Security/Operations Building also houses the ISFSJ security staff, security equipment, and communications equipment. Access to the ISFSI protected area is controlled and monitored by the security staff. | |||
The ISFSI operates under the provisions of a general license utilizing the UJMSTM spent fuel storage/transportation system. The UMSTM system is licensed under a Certificate of Compliance issued by the U.S. Nuclear Regulatory Commission (NRC) in accordance with 10 CFR Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste". | |||

3.0 ISFSI ACCIDENT TYPES. DETECTION AND CONSEQUENCES 3.1 Radiological Events There are no postulated credible ISFSI accident conditions that would impose a radiological hazard to personnel beyond the ISFSI Controlled Area boundary. There are no credible design basis accidents that would exceed the EPA PAGs at the ISESI Controlled Area boundary. In the event of an ISFSI accident condition, the associated radiological hazards are limited to personnel onsite at the time of the event. | |||
The postulated ISFSI accident conditions are described in Chapter 11 of the Safety Analysis Report for the UMS Universal Storage System developed by NAC International (Reference 4). | |||
3.2 Non-Radiological Events The spectrum ofIJSFSI non-radiological events that could necessitate implementation of this Emergency Plan is limited. These events fall into the category of general industrial incidents (e.g. fire, explosion, toxic material release, etc.), natural and destructive phenomena (hurricane, tornado, etc.) or security events. These events are further described in Chapter 11 of the Safety Analysis Report for the UMSUniversal Storage System. The determination of which, events are included is based on the probability of occurrence, the potential severity and the potential impact on the facility of the event. | |||
3.2.1 Tip-Over of Vertical Concrete Cask A hypothetical non-credible accident condition has been postulated involving the non-mechanistic tip-over of a vertical concrete storage cask. Functionally, the cask is not expected to suffer significant adverse consequences due to this event. The concrete cask and canister are expected to continue providing design basis shielding, geometry control of contents, and contents confinement performance. The tipped-over configuration of the concrete cask will be obvious during a Site inspection following the initiating event. | |||
There is an adverse localized radiological consequence due to the hypothetical tip-over event since the bottom end of the concrete cask has significantly less shielding than the sides and top of these same components. The estimated dose rate from the-bottom of a tipped-over cask is calculated to be approximately 34 rem/hr at 1 meter, 4 rem/hr at 4 meters, and < 10Omrem/hr at 100 meters (NAC-SAR). Following a tip-over event, supplemental shielding should be used until the concrete cask can be up-righted. Surface and top and bottom edges of the concrete cask are expected to exhibit cracking and possible loss of concrete down to the layer of reinforcing bar. The increased dose rate due to this cracking is not expected to be significant. There are no credible events expected to result in a cask tip-over. | |||
3.1 REV 7 | |||
3.2.2 Tornado and Tornado Driven Missiles It is not expected that the performance of the UMS storage cask will be significantly affected by a tornado event. It is not anticipated that postulated tornado wind loading and missile impacts are capable of overturning a cask, or penetrating the cask concrete boundary and affecting the fuel storage canister. A tornado event can be visually observed. Advanced warning of a tornado and of tornado sightings may be received from the National Weather Service, local radio and television stations, local law enforcement personnel, and site personnel. An inspection of the cask exterior surface following a tornado event is required. The inspection should be directed at ensuring the inlets and outlets have not become blocked by wind-blown debris and checking for obvious concrete surface damage. Damage to the vertical concrete cask after a design basis tornado is not anticipated to result in radiation exposure at the Controlled Area boundary that would exceed the EPA PAGs exposure guidelines. The penetrating missile impact is estimated to reduce the concrete shielding thickness, locally at the point of impact, by approximately 6 inches. Localized cask surface dose rates for the removal of 6 inches of concrete are estimated to be less than 250 rnrem/hr (NAC SAR Section 11.2.11). | |||
3.2.3 Explosions. | |||
An explosion affecting the Universal Storage System may be caused by industrial accidents or the presence of explosive substances in the vicinity of the ISFSI. It is not anticipated that explosive substances will be stored or used at the JSFSJ. An explosion in the vicinity of the ISFSI would be sensed by on-duty ISFSJ personnel. In the event of a nearby explosion, an inspection of the concrete casks may be required to check cask integrity, to ensure that the air inlets and outlets are free of debris, and to ensure that the monitoring system and screens are intact. There are no anticipated off-site radiological consequences for this event. | |||
3.2.4 Seismic Event The earthquake evaluation shows that the loaded or empty vertical concrete casks are not expected to tip over or slide in the event of an earthquake. Significant earthquakes would be detected by ground motion. Inspection of the vertical concrete casks is required following an earthquake event. The proper positioning of the Concrete casks should be verified to ensure they maintain the established spacing requirements. The temperature monitoring system should be checked for operation. There are no anticipated off-site radiological consequences for earthquake events. | |||
3.2 REV 7 | |||
3.2.5 Fires There are no flammable materials routinely present in the ISFSI cask storage area. A "combustible liquid control zone" shall be established for the ISFSI itself, which shall be a minimum of 10 feet from the outside perimeter of the VCC. The total liquid combustibles allowed within the zone cannot exceed 50 gallons and must be in direct support of ISFSI operations or maintenance. A fire in the vicinity of the ISFSI will be detected by observation of the fire or smoke. Upon detection of a fire, appropriate actions should be taken by site personnel to report andlor extinguish the fire. The concrete cask should be inspected for general deterioration of the concrete, loss of shielding (spalling of concrete), exposed reinforcing bar, and surface discoloration that could affect heat rejection. This inspection serves as the basis for the determination of any repair activities necessary to return the concrete cask to its design basis configuration. There may be local spalling of concrete during the fire event, which could lead to some minor reduction in shielding effectiveness. The principal effect would be local increases in radiation dose rates on the cask surface. There are no off-site radiological consequences anticipated for this event. | |||
3.2.6 Abnormal Cask Outlet Temperature Shift This event involves an abnormal outlet temperature shift caused by a partial or full blockage of the vertical concrete cask air inlets and outlets that could result in the heat up of the fuel cladding, the fuel basket and the concrete, with the temperature potentially reaching the design basis limiting temperature. Full blockage could result in these temperature limits potentially being exceeded after 24 hours. Blockage of the cask air inlets and outlets will be detected by the Cask outlet temperature monitoring system. Any obstruction blocking the air inlets and outlets must be manually removed. There are no significant radiological consequences for this event at the Controlled Area boundary, as the vertical concrete cask is expected to retain its shielding performance (NAC SARL 11.2.13). | |||
3.2.7 Other Conditions 3.2.7.1 Off-Normal Canister Handling Events These events would involve off-normal occurrences during the handling or transfer of a loaded transportable storage canister (TSC), i.e., during the installation or removal of the canister in or from the vertical concrete cask (VCC), or the transfer cask (TFR). | |||
Unintended loads could be applied to the canister due to misalignment or faulty crane operation, or due to inattention of the operator. The event is expected to be obvious to the operators at the time of occurrence. There is no anticipated deterioration of the canister or fuel basket performance due to this event. There are no anticipated off-site radiological consequences associated with this off-normal event. | |||
3.3 REV 7 | |||
3.2.7.2 Drop of Vertical Concrete Cask This event involves dropping a loaded vertical concrete cask during routine handling operations. This event may be due to the failure of one or more of the cask lifting jacks or of the air pad system. The maximum lift height shall be limited to less than 24 inches by administrative controls. The event would be detected by the operators as it occurs. | |||
The damaged cask should be inspected and repaired prior to continued use. There are no anticipated off-site radiological consequences for this event. | |||
3.2.7.3 Flood Event The UMS storage system vertical concrete casks have been evaluated for a design basis flood condition having a 50-foot depth of water and a water velocity of 15 feet per second. This flood depth would frully submerge the vertical concrete casks. The analysis shows that the vertical concrete casks are not expected to slide or overturn during the design basis flood. Small floods may lead to blockage of the concrete cask air inlet vents. | |||
Partial and full blockage of air inlets is described in Section 3.2.6 of this plan. Flooding conditions would be detected by the ISFSI staff or personnel working in the vicinity of the ISFSI. A potential exists for collection of debris or accumulation of silt at the base ofo the cask, which could clog or obstruct the air inlet vents. Operation of the temperature monitoring system should be verified, as flood conditions may have impaired its,* | |||
operation. There are no anticipated off-site radiological consequences associated with the design basis flood event. | |||
3.2.7.4 Lightning Strike Event Since the vertical concrete casks are located on an unsheltered pad, the casks may be subject to a lightning strike. A lightning strike on a concrete cask may be visually detected at the time of the strike, or by visible surface discoloration at the point of entry or exit of the current flow. There are no anticipated off-site radiological consequences due to the lightning event. | |||
3.3 Security Event Events that impact the security of the ISFSI are discussed in the ISESI Security Plan. | |||
These events represent a threat to the level of safety of the ISFSI due to unauthorized access, the introduction of threatening materials, or the use of hostile force in designated security areas. Security event detection and response is described in the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. The Emergency Plan may be implemented if necessary in response to a security event. | |||
Events that fall into these areas will be categorized under the appropriate category in the classification process discussed in Section 4, CLASSIFICATION OF ACCIDENTS. | |||
3.4 REV 7 | |||
4.0 CLASSIFICATION OF ACCIDENTS Based on NUJREG-l1140,"Regulatory Analysis of Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees", the NRC has determined that there are no credible design basis accidents that would exceed the EPA PAGs at an ISFSI Controlled Area boundary. Emergency classification guidance in Appendix F of Nuclear Energy Institute document NEI 99-01 (Final Rev. 4), "Methodology for Development of Emergency Action Levels," states, "The expectations of offsite response to an 'alert' classified under a 10 CFR 72.32 emergency plan are generally consistent with those for a notification of unusual event in a 10 CFR 50.47 emergency plan, i.e., to provide assistance if requested." The NEI 99-01 guidance is utilized in this plan to classify Maine Yankee ISFSI emergency events. The NRC Regulatory Analysis for Rev. 4 of Reg Guide 1.101 (Reference 5) to accept NET199-01 determined that the guidance in NE1 99-01 is appropriate for developing site specific EALs, to meet the intent of 10 CFR 50.47(b) (4) and Appendix F to Part 50. | |||
Accidents and off-normal events that are analyzed for the ISFSI, including some events considered to be non-credible, have been reviewed and assigned a classification. There are no credible design basis accidents that would exceed the EPA PAGs at the ISFSI Controlled Area boundary. Table 4-1 summarizes events that are classified as an Unusual Event. | |||
This plan classifies events based on predetermined Emergency Action Levels (EALs). | |||
This approach provides a simple, predetermined response to an emergency event or accident, allowing a coordinated and phased approach to the eventual mitigation of the conditions and restoring the facility to a safe status. | |||
4.1 Definitions 4.1.1 Unusual Event (U-E) | |||
Events are in process or have occurred which indicate a potential degradation of the level of safety of the facility. No release of radioactive material requiring offsite response or monitoring is expected. | |||
4.2 Categories of Events Per the Emergency Action Levels (EALs) guidance in NE1 99-01 (Reference 2), there are two categories of ISFSI events that can lead to an accident being classified as an Unusual Event (UF). The ISS/ED has the discretion to classify events based on the classification level definition. This discretion should be used when conditions or events are observed and no specific Initiating Condition (IC) / Emergency Action Level (EAL) is apparent. | |||
The UBE classification will heighten awareness of the abnormal condition. Table 4-1 lists the initiating conditions, associated emergency action levels, and the applicable NRC emergency classification levels. | |||
4.1 REV 7 | |||
4.2.1 Damage to a Loaded Vertical Concrete Cask That May Damage the Fuel or GTCC Confinement Boundary UE A UE classification for these IC/EALs is warranted on the basis of the occurrence of an event of sufficient magnitude that a loaded VCC is severely damaged, which may be indicative of potential damage to a cask confinement boundary. This classification includes events involving loss of a loaded fuel storage cask confinement boundary, leading to degradation of the fuel during storage or posing an operational safety problem with respect to removal of the degraded fuel confinement boundary from storage. Natural phenomena events and accident conditions in which a loaded VCC is damaged are classified at the UPE level. Cask seal integrity issues discovered during leakage testing associated with normal canister processing would be addressed in accordance with NAC technical specifications, or SAR* required actions, therefore, classification should not be made based on loss of seal integrity by itself. However, loss or potential loss of seal integrity coincident with an accident condition or natural phenomena that clearly affects the cask would justify a UPE classification. The 1SF SI vertical concrete storage casks are routinely monitored by site personnel such that any degradation would be detected. | |||
Increases in radiation levels may be indicative of degradation of a storage cask. | |||
4.2.2 Confirmed Security Event with Potential Loss of Level of Safety of the ISFSI LYE These IC/EALs provide a UE cl!assification for security events involving a potential loss of the level of safety of the ISFSI based on the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. | |||

5.0 EMERGENCY RESPONSE Emergency In the event ofResponse Overview an accident at the facility, actions will be taken by facility staff to report the event to the ISFSI Shift Supervisor (ISS) and to minimize the impact of the event. The primary objective of the initial responders is to assess the situation and minimize the risk imposed on workers and the general public. This involves initiation of required actions to mitigate a particular hazard. Subsequent actions include notifications, staff accountability, staff augmentation, and implementation of onsite corrective actions as necessary. The ISFSI Shift Supervisor becomes the Emergency Director (IS S/ED) upon classification and declaration of an unusual event. | |||
5.1 Notification and Activation When an emergency condition is recognized, the event is classified and declared by the ISS/ED and mitigating actions are taken to minimize the progression of the event. These actions are initiated by available resources. The IS S/ED will request any offsite assistance that may be necessary due to the nature of the event. Following initial notifications, the Maine State Police (MSP) and the Nuclear Regulatory Commission (NRC) will be notified of the event and mitigating actions in progress or that have been completed. | |||
Figure 5-1 depicts the initial .notification and activation process. | |||
5.1.1 Maine Yankee Emergency Support Staff The ISS/ED or designee will direct ISFSI shift personnel to notify the ISFSI Support Staff of an event, if necessary. This will be accomplished by the commercial telephone system (i.e., land based, cell based, satellite based service). In the event the initiating conditions constitute a Security Event, these notifications will be made by the IS S/ED or designee. [ | |||
Notifications to supplement support positions should be completed within one hour of the event declaration. | |||
5.1.2 Offsite Organizations Following notification of the Maine Yankee ISFSI Support Staff, the Maine State Police (MSP) will be contacted and provided pertinent information regarding the event, actions taken to mitigate the event and notification of any assistance which may be necessary from local organizations (i.e. fire, ambulance, police response). Notification to the MSP shall be comPleted within one hour of event declaration. Depending on the need for immediate outside assistance, these notifications may be initiated in an accelerated manner (i.e. immediate need for fire fighting capabilities or medical assistance). The MSP Headquarters Communications Center is staffed 24 hours a day, 7 days a week. The MSP have the capability to contact State and county emergency response personnel, if needed. | |||
The MSP will initiate notification to appropriate State Officials in the Maine Emergency Management Agency (MEMA), Division of Environmental Health (D)EH) and others as designated in the State's notification protocol, based on the event. | |||
The NRC will be notified after the notification of the MSP and no later than one hour after the emergency was declared. | |||
5.1 REV 7 | |||
5.1.3 Information to be Communicated A pre-scripted format is used to ensure consistent information is provided to the MSP and the NRC. | |||
At a minimum, the following information will be provided during the initial notification of the event: | |||
Event Classification; Date/Time of Classification; Reason or events causing the condition; General description of damage to major structures/areas; Personal injuries; Status of offsite assistance (fire/medical/other); | |||

Company's PowerYankee (MYAPC) plan This document to for responding describes the Maine emergencies that may ariseAtomic Yankee at the Maine Independent Spent Fuel Storage Installation (ISFSI). The overall purpose of the plan is to delineate the actions necessary to safeguard ISFSI personnel and minimize damage to site property in the event of an incident at the ISFSI. Analyses of the possible design basis events and consequences are presented in the Safety Analysis Report for the UMS Universal Storage System (NAC UMS SAR) used at the ISFSI for dry spent fuiel storage. | |||
The analyses of the potential radiological impact of an accident at the Maine Yankee site indicates that any releases beyond the ISESI Controlled Area boundary are expected to be less than the U.S. Environmental Protection Agency (EPA) protective action guide (PAG) exposure levels, as detailed in EPA-400-R-92-001, Manual of Protective Action Guides and Protective Actions for Nuclear Incidents. Exposure levels which may warrant pre-planned response measures are generally limited to the Controlled Area. For this reason, radiological emergency planning is focused on the Controlled Area. | |||

2.0 FACILITY DESCRIPTION 2.1 Maine Yankee Site 2.1.1 Overview The Maine Yankee site is located in the town of Wiscasset, Lincoln County, Maine. Site coordinates are approximately 43 degrees 57 minutes 5 seconds north latitude and 69 degrees 41 minutes 45 seconds west longitude. The site is bounded by the Back River on the east, mainland on the north and Bailey Cove on the west. The ISFSI is located on a peninsula known as Bailey Point, which extends south to Montsweag Bay (Figure 2-1). | |||
The ISFSI facility is depicted on Figure 2-2. Spent nuclear fuel is in interim storage within the specified secure fuel storage area and will be monitored by the ISFSJ staff. | |||
2.2 General Area Within 5 miles of the site, land use is largely rural residential, small businesses, summer houses, idle farmland and forest. Housing is scattered along principal roads and is concentrated only in the center of Wiscasset. | |||
The waters of the Back River, Montsweag Bay and associated tributaries are tidal and open to boating, both commercial and recreational. Regulation of boating is the responsibility of the U.S. Coast Guard and the State of Maine. The primary type of boating in the Mon._tswe~ag B~ay - Back River is shallow draft Pleasure boats. With no commercial traffic in the area, there is essentially no hazard to the site from potential accidents with commercial barges or boats carrying hazardous, toxic or explosive materials. | |||
Industrial activity within the general area of the JSFSJ is minimal. The largest industrial facility is the Bath Iron Works, a shipbuilding facility located on the Kennebec River approximately 7 miles southwest in the city of Bath. | |||
The Wiscasset Municipal Airport is the nearest airport to the site and is located approximately one .mile northwest of the site. It consists of one runway (approximately 3,400 feet long by 75 feet wide). This runway is aligned such that takeoffs and landings are on headings of either 070 or 250 (the predominant heading is 250). The majorities of aircraft that are serviced by this facility are privately owned and are similar to the Piper Colt, Cherokee, and Cessna 150 and 172 type craft. The largest aircraftthat typically use the facility are similar to the Lear 25, Citation II and Rockwell Commander type craft. | |||
2.1 REV 7 | |||
2.3 Independent Spent Fuel Storage Installation (ISFSI) | |||
The ISFSI is designed for interim storage of fuel for a minimum of 50 years in a contained shielded system. The ISFSI utilizes the Universal MPC System (UMSTM) developed by NAC International. The UMSTM is a canister-based multi-purpose canister (MPG) system designed for both storage and transportation of spent nuclear fuel. The canister-based spent fuel storage system is a passive system which utilizes an outer concrete cylinder called a Vertical Concrete Cask (VCC) to protect and shield the inner sealed metal canister. The VCC is vented for natural convection cooling and has no moving parts. Decay heat from the loaded fuel storage canister in the VCC is dissipated to the surrounding air by a once through buoyancy driven airflow. The VCC provides radiation shielding, as well as protection from tornado missiles and earthquakes. | |||
The ISFST site consists of a Protected Area (PA) for fuel storage and a Security/Operations Building. The ISFSI has a Controlled Area that extends at least 300 meters from the nuclear fuel storage area. | |||
The PA has sixteen concrete storage pads, and is surrounded by a security fence and a nuisance fence with an isolation zone between the two fences. A partial earthen berm is provided around the facility to reduce the visual impact of the facility. The ISFSI contains a total of 64 storage casks, with one sealed fuel canister per VCC. The types of canisters stored in the storage casks include 60 casks for spent fuel and 4 casks for Greater Than Class C (GTCC) waste. Sixteen storage pads of equal size are provided for uniformity, which allows for storage of 4 casks per storage pad. The ISFSI site is arranged to provide maneuvering room around the storage pads for access with a cask heavy haul tractor-trailer. | |||
The Security/Operations Building provides offices and work space for the operating and maintenance personnel, including the Radiation Controls Checkpoint lunch/conference rooms, restrooms, locker rooms, document control room, spare parts storage, and a diesel generator for emergency power. The Security/Operations Building also houses the ISFSJ security staff, security equipment, and communications equipment. Access to the ISFSI protected area is controlled and monitored by the security staff. | |||
The ISFSI operates under the provisions of a general license utilizing the UJMSTM spent fuel storage/transportation system. The UMSTM system is licensed under a Certificate of Compliance issued by the U.S. Nuclear Regulatory Commission (NRC) in accordance with 10 CFR Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste". | |||

3.0 ISFSI ACCIDENT TYPES. DETECTION AND CONSEQUENCES 3.1 Radiological Events There are no postulated credible ISFSI accident conditions that would impose a radiological hazard to personnel beyond the ISFSI Controlled Area boundary. There are no credible design basis accidents that would exceed the EPA PAGs at the ISESI Controlled Area boundary. In the event of an ISFSI accident condition, the associated radiological hazards are limited to personnel onsite at the time of the event. | |||
The postulated ISFSI accident conditions are described in Chapter 11 of the Safety Analysis Report for the UMS Universal Storage System developed by NAC International (Reference 4). | |||
3.2 Non-Radiological Events The spectrum ofIJSFSI non-radiological events that could necessitate implementation of this Emergency Plan is limited. These events fall into the category of general industrial incidents (e.g. fire, explosion, toxic material release, etc.), natural and destructive phenomena (hurricane, tornado, etc.) or security events. These events are further described in Chapter 11 of the Safety Analysis Report for the UMSUniversal Storage System. The determination of which, events are included is based on the probability of occurrence, the potential severity and the potential impact on the facility of the event. | |||
3.2.1 Tip-Over of Vertical Concrete Cask A hypothetical non-credible accident condition has been postulated involving the non-mechanistic tip-over of a vertical concrete storage cask. Functionally, the cask is not expected to suffer significant adverse consequences due to this event. The concrete cask and canister are expected to continue providing design basis shielding, geometry control of contents, and contents confinement performance. The tipped-over configuration of the concrete cask will be obvious during a Site inspection following the initiating event. | |||
There is an adverse localized radiological consequence due to the hypothetical tip-over event since the bottom end of the concrete cask has significantly less shielding than the sides and top of these same components. The estimated dose rate from the-bottom of a tipped-over cask is calculated to be approximately 34 rem/hr at 1 meter, 4 rem/hr at 4 meters, and < 10Omrem/hr at 100 meters (NAC-SAR). Following a tip-over event, supplemental shielding should be used until the concrete cask can be up-righted. Surface and top and bottom edges of the concrete cask are expected to exhibit cracking and possible loss of concrete down to the layer of reinforcing bar. The increased dose rate due to this cracking is not expected to be significant. There are no credible events expected to result in a cask tip-over. | |||
3.1 REV 7 | |||
- | |||
3.2.2 Tornado and Tornado Driven Missiles It is not expected that the performance of the UMS storage cask will be significantly affected by a tornado event. It is not anticipated that postulated tornado wind loading and missile impacts are capable of overturning a cask, or penetrating the cask concrete boundary and affecting the fuel storage canister. A tornado event can be visually observed. Advanced warning of a tornado and of tornado sightings may be received from the National Weather Service, local radio and television stations, local law enforcement personnel, and site personnel. An inspection of the cask exterior surface following a tornado event is required. The inspection should be directed at ensuring the inlets and outlets have not become blocked by wind-blown debris and checking for obvious concrete surface damage. Damage to the vertical concrete cask after a design basis tornado is not anticipated to result in radiation exposure at the Controlled Area boundary that would exceed the EPA PAGs exposure guidelines. The penetrating missile impact is estimated to reduce the concrete shielding thickness, locally at the point of impact, by approximately 6 inches. Localized cask surface dose rates for the removal of 6 inches of concrete are estimated to be less than 250 rnrem/hr (NAC SAR Section 11.2.11). | |||
3.2.3 Explosions. | |||
An explosion affecting the Universal Storage System may be caused by industrial accidents or the presence of explosive substances in the vicinity of the ISFSI. It is not anticipated that explosive substances will be stored or used at the JSFSJ. An explosion in the vicinity of the ISFSI would be sensed by on-duty ISFSJ personnel. In the event of a nearby explosion, an inspection of the concrete casks may be required to check cask integrity, to ensure that the air inlets and outlets are free of debris, and to ensure that the monitoring system and screens are intact. There are no anticipated off-site radiological consequences for this event. | |||
3.2.4 Seismic Event The earthquake evaluation shows that the loaded or empty vertical concrete casks are not expected to tip over or slide in the event of an earthquake. Significant earthquakes would be detected by ground motion. Inspection of the vertical concrete casks is required following an earthquake event. The proper positioning of the Concrete casks should be verified to ensure they maintain the established spacing requirements. The temperature monitoring system should be checked for operation. There are no anticipated off-site radiological consequences for earthquake events. | |||
3.2 REV 7 | |||
3.2.5 Fires There are no flammable materials routinely present in the ISFSI cask storage area. A "combustible liquid control zone" shall be established for the ISFSI itself, which shall be a minimum of 10 feet from the outside perimeter of the VCC. The total liquid combustibles allowed within the zone cannot exceed 50 gallons and must be in direct support of ISFSI operations or maintenance. A fire in the vicinity of the ISFSI will be detected by observation of the fire or smoke. Upon detection of a fire, appropriate actions should be taken by site personnel to report andlor extinguish the fire. The concrete cask should be inspected for general deterioration of the concrete, loss of shielding (spalling of concrete), exposed reinforcing bar, and surface discoloration that could affect heat rejection. This inspection serves as the basis for the determination of any repair activities necessary to return the concrete cask to its design basis configuration. There may be local spalling of concrete during the fire event, which could lead to some minor reduction in shielding effectiveness. The principal effect would be local increases in radiation dose rates on the cask surface. There are no off-site radiological consequences anticipated for this event. | |||
3.2.6 Abnormal Cask Outlet Temperature Shift This event involves an abnormal outlet temperature shift caused by a partial or full blockage of the vertical concrete cask air inlets and outlets that could result in the heat up of the fuel cladding, the fuel basket and the concrete, with the temperature potentially reaching the design basis limiting temperature. Full blockage could result in these temperature limits potentially being exceeded after 24 hours. Blockage of the cask air inlets and outlets will be detected by the Cask outlet temperature monitoring system. Any obstruction blocking the air inlets and outlets must be manually removed. There are no significant radiological consequences for this event at the Controlled Area boundary, as the vertical concrete cask is expected to retain its shielding performance (NAC SARL 11.2.13). | |||
3.2.7 Other Conditions 3.2.7.1 Off-Normal Canister Handling Events These events would involve off-normal occurrences during the handling or transfer of a loaded transportable storage canister (TSC), i.e., during the installation or removal of the canister in or from the vertical concrete cask (VCC), or the transfer cask (TFR). | |||
Unintended loads could be applied to the canister due to misalignment or faulty crane operation, or due to inattention of the operator. The event is expected to be obvious to the operators at the time of occurrence. There is no anticipated deterioration of the canister or fuel basket performance due to this event. There are no anticipated off-site radiological consequences associated with this off-normal event. | |||
3.3 REV 7 | |||
3.2.7.2 Drop of Vertical Concrete Cask This event involves dropping a loaded vertical concrete cask during routine handling operations. This event may be due to the failure of one or more of the cask lifting jacks or of the air pad system. The maximum lift height shall be limited to less than 24 inches by administrative controls. The event would be detected by the operators as it occurs. | |||
The damaged cask should be inspected and repaired prior to continued use. There are no anticipated off-site radiological consequences for this event. | |||
3.2.7.3 Flood Event The UMS storage system vertical concrete casks have been evaluated for a design basis flood condition having a 50-foot depth of water and a water velocity of 15 feet per second. This flood depth would frully submerge the vertical concrete casks. The analysis shows that the vertical concrete casks are not expected to slide or overturn during the design basis flood. Small floods may lead to blockage of the concrete cask air inlet vents. | |||
Partial and full blockage of air inlets is described in Section 3.2.6 of this plan. Flooding conditions would be detected by the ISFSI staff or personnel working in the vicinity of the ISFSI. A potential exists for collection of debris or accumulation of silt at the base ofo the cask, which could clog or obstruct the air inlet vents. Operation of the temperature monitoring system should be verified, as flood conditions may have impaired its,* | |||
operation. There are no anticipated off-site radiological consequences associated with the design basis flood event. | |||
3.2.7.4 Lightning Strike Event Since the vertical concrete casks are located on an unsheltered pad, the casks may be subject to a lightning strike. A lightning strike on a concrete cask may be visually detected at the time of the strike, or by visible surface discoloration at the point of entry or exit of the current flow. There are no anticipated off-site radiological consequences due to the lightning event. | |||
3.3 Security Event Events that impact the security of the ISFSI are discussed in the ISESI Security Plan. | |||
These events represent a threat to the level of safety of the ISFSI due to unauthorized access, the introduction of threatening materials, or the use of hostile force in designated security areas. Security event detection and response is described in the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. The Emergency Plan may be implemented if necessary in response to a security event. | |||
Events that fall into these areas will be categorized under the appropriate category in the classification process discussed in Section 4, CLASSIFICATION OF ACCIDENTS. | |||
3.4 REV 7 | |||
4.0 CLASSIFICATION OF ACCIDENTS Based on NUJREG-l1140,"Regulatory Analysis of Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees", the NRC has determined that there are no credible design basis accidents that would exceed the EPA PAGs at an ISFSI Controlled Area boundary. Emergency classification guidance in Appendix F of Nuclear Energy Institute document NEI 99-01 (Final Rev. 4), "Methodology for Development of Emergency Action Levels," states, "The expectations of offsite response to an 'alert' classified under a 10 CFR 72.32 emergency plan are generally consistent with those for a notification of unusual event in a 10 CFR 50.47 emergency plan, i.e., to provide assistance if requested." The NEI 99-01 guidance is utilized in this plan to classify Maine Yankee ISFSI emergency events. The NRC Regulatory Analysis for Rev. 4 of Reg Guide 1.101 (Reference 5) to accept NET199-01 determined that the guidance in NE1 99-01 is appropriate for developing site specific EALs, to meet the intent of 10 CFR 50.47(b) (4) and Appendix F to Part 50. | |||
Accidents and off-normal events that are analyzed for the ISFSI, including some events considered to be non-credible, have been reviewed and assigned a classification. There are no credible design basis accidents that would exceed the EPA PAGs at the ISFSI Controlled Area boundary. Table 4-1 summarizes events that are classified as an Unusual Event. | |||
This plan classifies events based on predetermined Emergency Action Levels (EALs). | |||
This approach provides a simple, predetermined response to an emergency event or accident, allowing a coordinated and phased approach to the eventual mitigation of the conditions and restoring the facility to a safe status. | |||
4.1 Definitions 4.1.1 Unusual Event (U-E) | |||
Events are in process or have occurred which indicate a potential degradation of the level of safety of the facility. No release of radioactive material requiring offsite response or monitoring is expected. | |||
4.2 Categories of Events Per the Emergency Action Levels (EALs) guidance in NE1 99-01 (Reference 2), there are two categories of ISFSI events that can lead to an accident being classified as an Unusual Event (UF). The ISS/ED has the discretion to classify events based on the classification level definition. This discretion should be used when conditions or events are observed and no specific Initiating Condition (IC) / Emergency Action Level (EAL) is apparent. | |||
The UBE classification will heighten awareness of the abnormal condition. Table 4-1 lists the initiating conditions, associated emergency action levels, and the applicable NRC emergency classification levels. | |||
4.1 REV 7 | |||
4.2.1 Damage to a Loaded Vertical Concrete Cask That May Damage the Fuel or GTCC Confinement Boundary UE A UE classification for these IC/EALs is warranted on the basis of the occurrence of an event of sufficient magnitude that a loaded VCC is severely damaged, which may be indicative of potential damage to a cask confinement boundary. This classification includes events involving loss of a loaded fuel storage cask confinement boundary, leading to degradation of the fuel during storage or posing an operational safety problem with respect to removal of the degraded fuel confinement boundary from storage. Natural phenomena events and accident conditions in which a loaded VCC is damaged are classified at the UPE level. Cask seal integrity issues discovered during leakage testing associated with normal canister processing would be addressed in accordance with NAC technical specifications, or SAR* required actions, therefore, classification should not be made based on loss of seal integrity by itself. However, loss or potential loss of seal integrity coincident with an accident condition or natural phenomena that clearly affects the cask would justify a UPE classification. The 1SF SI vertical concrete storage casks are routinely monitored by site personnel such that any degradation would be detected. | |||
Increases in radiation levels may be indicative of degradation of a storage cask. | |||
4.2.2 Confirmed Security Event with Potential Loss of Level of Safety of the ISFSI LYE These IC/EALs provide a UE cl!assification for security events involving a potential loss of the level of safety of the ISFSI based on the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. | |||

5.0 EMERGENCY RESPONSE Emergency In the event ofResponse Overview an accident at the facility, actions will be taken by facility staff to report the event to the ISFSI Shift Supervisor (ISS) and to minimize the impact of the event. The primary objective of the initial responders is to assess the situation and minimize the risk imposed on workers and the general public. This involves initiation of required actions to mitigate a particular hazard. Subsequent actions include notifications, staff accountability, staff augmentation, and implementation of onsite corrective actions as necessary. The ISFSI Shift Supervisor becomes the Emergency Director (IS S/ED) upon classification and declaration of an unusual event. | |||
5.1 Notification and Activation When an emergency condition is recognized, the event is classified and declared by the ISS/ED and mitigating actions are taken to minimize the progression of the event. These actions are initiated by available resources. The IS S/ED will request any offsite assistance that may be necessary due to the nature of the event. Following initial notifications, the Maine State Police (MSP) and the Nuclear Regulatory Commission (NRC) will be notified of the event and mitigating actions in progress or that have been completed. | |||
Figure 5-1 depicts the initial .notification and activation process. | |||
5.1.1 Maine Yankee Emergency Support Staff The ISS/ED or designee will direct ISFSI shift personnel to notify the ISFSI Support Staff of an event, if necessary. This will be accomplished by the commercial telephone system (i.e., land based, cell based, satellite based service). In the event the initiating conditions constitute a Security Event, these notifications will be made by the IS S/ED or designee. [ | |||
Notifications to supplement support positions should be completed within one hour of the event declaration. | |||
5.1.2 Offsite Organizations Following notification of the Maine Yankee ISFSI Support Staff, the Maine State Police (MSP) will be contacted and provided pertinent information regarding the event, actions taken to mitigate the event and notification of any assistance which may be necessary from local organizations (i.e. fire, ambulance, police response). Notification to the MSP shall be comPleted within one hour of event declaration. Depending on the need for immediate outside assistance, these notifications may be initiated in an accelerated manner (i.e. immediate need for fire fighting capabilities or medical assistance). The MSP Headquarters Communications Center is staffed 24 hours a day, 7 days a week. The MSP have the capability to contact State and county emergency response personnel, if needed. | |||
The MSP will initiate notification to appropriate State Officials in the Maine Emergency Management Agency (MEMA), Division of Environmental Health (D)EH) and others as designated in the State's notification protocol, based on the event. | |||
The NRC will be notified after the notification of the MSP and no later than one hour after the emergency was declared. | |||
5.1 REV 7 | |||
5.1.3 Information to be Communicated A pre-scripted format is used to ensure consistent information is provided to the MSP and the NRC. | |||
At a minimum, the following information will be provided during the initial notification of the event: | |||

1.0 INTRODUCTION
Company's PowerYankee (MYAPC) plan This document to for responding describes the Maine emergencies that may ariseAtomic Yankee at the Maine Independent Spent Fuel Storage Installation (ISFSI). The overall purpose of the plan is to delineate the actions necessary to safeguard ISFSI personnel and minimize damage to site property in the event of an incident at the ISFSI. Analyses of the possible design basis events and consequences are presented in the Safety Analysis Report for the UMS Universal Storage System (NAC UMS SAR) used at the ISFSI for dry spent fuiel storage.
The analyses of the potential radiological impact of an accident at the Maine Yankee site indicates that any releases beyond the ISESI Controlled Area boundary are expected to be less than the U.S. Environmental Protection Agency (EPA) protective action guide (PAG) exposure levels, as detailed in EPA-400-R-92-001, Manual of Protective Action Guides and Protective Actions for Nuclear Incidents. Exposure levels which may warrant pre-planned response measures are generally limited to the Controlled Area. For this reason, radiological emergency planning is focused on the Controlled Area.
1.1 REV 7
2.0 FACILITY DESCRIPTION 2.1 Maine Yankee Site 2.1.1 Overview The Maine Yankee site is located in the town of Wiscasset, Lincoln County, Maine. Site coordinates are approximately 43 degrees 57 minutes 5 seconds north latitude and 69 degrees 41 minutes 45 seconds west longitude. The site is bounded by the Back River on the east, mainland on the north and Bailey Cove on the west. The ISFSI is located on a peninsula known as Bailey Point, which extends south to Montsweag Bay (Figure 2-1).
The ISFSI facility is depicted on Figure 2-2. Spent nuclear fuel is in interim storage within the specified secure fuel storage area and will be monitored by the ISFSJ staff.
2.2 General Area Within 5 miles of the site, land use is largely rural residential, small businesses, summer houses, idle farmland and forest. Housing is scattered along principal roads and is concentrated only in the center of Wiscasset.
The waters of the Back River, Montsweag Bay and associated tributaries are tidal and open to boating, both commercial and recreational. Regulation of boating is the responsibility of the U.S. Coast Guard and the State of Maine. The primary type of boating in the Mon._tswe~ag B~ay - Back River is shallow draft Pleasure boats. With no commercial traffic in the area, there is essentially no hazard to the site from potential accidents with commercial barges or boats carrying hazardous, toxic or explosive materials.
Industrial activity within the general area of the JSFSJ is minimal. The largest industrial facility is the Bath Iron Works, a shipbuilding facility located on the Kennebec River approximately 7 miles southwest in the city of Bath.
The Wiscasset Municipal Airport is the nearest airport to the site and is located approximately one .mile northwest of the site. It consists of one runway (approximately 3,400 feet long by 75 feet wide). This runway is aligned such that takeoffs and landings are on headings of either 070 or 250 (the predominant heading is 250). The majorities of aircraft that are serviced by this facility are privately owned and are similar to the Piper Colt, Cherokee, and Cessna 150 and 172 type craft. The largest aircraftthat typically use the facility are similar to the Lear 25, Citation II and Rockwell Commander type craft.
2.1 REV 7
2.3 Independent Spent Fuel Storage Installation (ISFSI)
The ISFSI is designed for interim storage of fuel for a minimum of 50 years in a contained shielded system. The ISFSI utilizes the Universal MPC System (UMSTM) developed by NAC International. The UMSTM is a canister-based multi-purpose canister (MPG) system designed for both storage and transportation of spent nuclear fuel. The canister-based spent fuel storage system is a passive system which utilizes an outer concrete cylinder called a Vertical Concrete Cask (VCC) to protect and shield the inner sealed metal canister. The VCC is vented for natural convection cooling and has no moving parts. Decay heat from the loaded fuel storage canister in the VCC is dissipated to the surrounding air by a once through buoyancy driven airflow. The VCC provides radiation shielding, as well as protection from tornado missiles and earthquakes.
The ISFST site consists of a Protected Area (PA) for fuel storage and a Security/Operations Building. The ISFSI has a Controlled Area that extends at least 300 meters from the nuclear fuel storage area.
The PA has sixteen concrete storage pads, and is surrounded by a security fence and a nuisance fence with an isolation zone between the two fences. A partial earthen berm is provided around the facility to reduce the visual impact of the facility. The ISFSI contains a total of 64 storage casks, with one sealed fuel canister per VCC. The types of canisters stored in the storage casks include 60 casks for spent fuel and 4 casks for Greater Than Class C (GTCC) waste. Sixteen storage pads of equal size are provided for uniformity, which allows for storage of 4 casks per storage pad. The ISFSI site is arranged to provide maneuvering room around the storage pads for access with a cask heavy haul tractor-trailer.
The Security/Operations Building provides offices and work space for the operating and maintenance personnel, including the Radiation Controls Checkpoint lunch/conference rooms, restrooms, locker rooms, document control room, spare parts storage, and a diesel generator for emergency power. The Security/Operations Building also houses the ISFSJ security staff, security equipment, and communications equipment. Access to the ISFSI protected area is controlled and monitored by the security staff.
The ISFSI operates under the provisions of a general license utilizing the UJMSTM spent fuel storage/transportation system. The UMSTM system is licensed under a Certificate of Compliance issued by the U.S. Nuclear Regulatory Commission (NRC) in accordance with 10 CFR Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste".

3.0 ISFSI ACCIDENT TYPES. DETECTION AND CONSEQUENCES 3.1 Radiological Events There are no postulated credible ISFSI accident conditions that would impose a radiological hazard to personnel beyond the ISFSI Controlled Area boundary. There are no credible design basis accidents that would exceed the EPA PAGs at the ISESI Controlled Area boundary. In the event of an ISFSI accident condition, the associated radiological hazards are limited to personnel onsite at the time of the event.
The postulated ISFSI accident conditions are described in Chapter 11 of the Safety Analysis Report for the UMS Universal Storage System developed by NAC International (Reference 4).
3.2 Non-Radiological Events The spectrum ofIJSFSI non-radiological events that could necessitate implementation of this Emergency Plan is limited. These events fall into the category of general industrial incidents (e.g. fire, explosion, toxic material release, etc.), natural and destructive phenomena (hurricane, tornado, etc.) or security events. These events are further described in Chapter 11 of the Safety Analysis Report for the UMSUniversal Storage System. The determination of which, events are included is based on the probability of occurrence, the potential severity and the potential impact on the facility of the event.
3.2.1 Tip-Over of Vertical Concrete Cask A hypothetical non-credible accident condition has been postulated involving the non-mechanistic tip-over of a vertical concrete storage cask. Functionally, the cask is not expected to suffer significant adverse consequences due to this event. The concrete cask and canister are expected to continue providing design basis shielding, geometry control of contents, and contents confinement performance. The tipped-over configuration of the concrete cask will be obvious during a Site inspection following the initiating event.
There is an adverse localized radiological consequence due to the hypothetical tip-over event since the bottom end of the concrete cask has significantly less shielding than the sides and top of these same components. The estimated dose rate from the-bottom of a tipped-over cask is calculated to be approximately 34 rem/hr at 1 meter, 4 rem/hr at 4 meters, and < 10Omrem/hr at 100 meters (NAC-SAR). Following a tip-over event, supplemental shielding should be used until the concrete cask can be up-righted. Surface and top and bottom edges of the concrete cask are expected to exhibit cracking and possible loss of concrete down to the layer of reinforcing bar. The increased dose rate due to this cracking is not expected to be significant. There are no credible events expected to result in a cask tip-over.
3.1 REV 7
3.2.2 Tornado and Tornado Driven Missiles It is not expected that the performance of the UMS storage cask will be significantly affected by a tornado event. It is not anticipated that postulated tornado wind loading and missile impacts are capable of overturning a cask, or penetrating the cask concrete boundary and affecting the fuel storage canister. A tornado event can be visually observed. Advanced warning of a tornado and of tornado sightings may be received from the National Weather Service, local radio and television stations, local law enforcement personnel, and site personnel. An inspection of the cask exterior surface following a tornado event is required. The inspection should be directed at ensuring the inlets and outlets have not become blocked by wind-blown debris and checking for obvious concrete surface damage. Damage to the vertical concrete cask after a design basis tornado is not anticipated to result in radiation exposure at the Controlled Area boundary that would exceed the EPA PAGs exposure guidelines. The penetrating missile impact is estimated to reduce the concrete shielding thickness, locally at the point of impact, by approximately 6 inches. Localized cask surface dose rates for the removal of 6 inches of concrete are estimated to be less than 250 rnrem/hr (NAC SAR Section 11.2.11).
3.2.3 Explosions.
An explosion affecting the Universal Storage System may be caused by industrial accidents or the presence of explosive substances in the vicinity of the ISFSI. It is not anticipated that explosive substances will be stored or used at the JSFSJ. An explosion in the vicinity of the ISFSI would be sensed by on-duty ISFSJ personnel. In the event of a nearby explosion, an inspection of the concrete casks may be required to check cask integrity, to ensure that the air inlets and outlets are free of debris, and to ensure that the monitoring system and screens are intact. There are no anticipated off-site radiological consequences for this event.
3.2.4 Seismic Event The earthquake evaluation shows that the loaded or empty vertical concrete casks are not expected to tip over or slide in the event of an earthquake. Significant earthquakes would be detected by ground motion. Inspection of the vertical concrete casks is required following an earthquake event. The proper positioning of the Concrete casks should be verified to ensure they maintain the established spacing requirements. The temperature monitoring system should be checked for operation. There are no anticipated off-site radiological consequences for earthquake events.
3.2 REV 7
3.2.5 Fires There are no flammable materials routinely present in the ISFSI cask storage area. A "combustible liquid control zone" shall be established for the ISFSI itself, which shall be a minimum of 10 feet from the outside perimeter of the VCC. The total liquid combustibles allowed within the zone cannot exceed 50 gallons and must be in direct support of ISFSI operations or maintenance. A fire in the vicinity of the ISFSI will be detected by observation of the fire or smoke. Upon detection of a fire, appropriate actions should be taken by site personnel to report andlor extinguish the fire. The concrete cask should be inspected for general deterioration of the concrete, loss of shielding (spalling of concrete), exposed reinforcing bar, and surface discoloration that could affect heat rejection. This inspection serves as the basis for the determination of any repair activities necessary to return the concrete cask to its design basis configuration. There may be local spalling of concrete during the fire event, which could lead to some minor reduction in shielding effectiveness. The principal effect would be local increases in radiation dose rates on the cask surface. There are no off-site radiological consequences anticipated for this event.
3.2.6 Abnormal Cask Outlet Temperature Shift This event involves an abnormal outlet temperature shift caused by a partial or full blockage of the vertical concrete cask air inlets and outlets that could result in the heat up of the fuel cladding, the fuel basket and the concrete, with the temperature potentially reaching the design basis limiting temperature. Full blockage could result in these temperature limits potentially being exceeded after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Blockage of the cask air inlets and outlets will be detected by the Cask outlet temperature monitoring system. Any obstruction blocking the air inlets and outlets must be manually removed. There are no significant radiological consequences for this event at the Controlled Area boundary, as the vertical concrete cask is expected to retain its shielding performance (NAC SARL 11.2.13).
3.2.7 Other Conditions 3.2.7.1 Off-Normal Canister Handling Events These events would involve off-normal occurrences during the handling or transfer of a loaded transportable storage canister (TSC), i.e., during the installation or removal of the canister in or from the vertical concrete cask (VCC), or the transfer cask (TFR).
Unintended loads could be applied to the canister due to misalignment or faulty crane operation, or due to inattention of the operator. The event is expected to be obvious to the operators at the time of occurrence. There is no anticipated deterioration of the canister or fuel basket performance due to this event. There are no anticipated off-site radiological consequences associated with this off-normal event.
3.3 REV 7
3.2.7.2 Drop of Vertical Concrete Cask This event involves dropping a loaded vertical concrete cask during routine handling operations. This event may be due to the failure of one or more of the cask lifting jacks or of the air pad system. The maximum lift height shall be limited to less than 24 inches by administrative controls. The event would be detected by the operators as it occurs.
The damaged cask should be inspected and repaired prior to continued use. There are no anticipated off-site radiological consequences for this event.
3.2.7.3 Flood Event The UMS storage system vertical concrete casks have been evaluated for a design basis flood condition having a 50-foot depth of water and a water velocity of 15 feet per second. This flood depth would frully submerge the vertical concrete casks. The analysis shows that the vertical concrete casks are not expected to slide or overturn during the design basis flood. Small floods may lead to blockage of the concrete cask air inlet vents.
Partial and full blockage of air inlets is described in Section 3.2.6 of this plan. Flooding conditions would be detected by the ISFSI staff or personnel working in the vicinity of the ISFSI. A potential exists for collection of debris or accumulation of silt at the base ofo the cask, which could clog or obstruct the air inlet vents. Operation of the temperature monitoring system should be verified, as flood conditions may have impaired its,*
operation. There are no anticipated off-site radiological consequences associated with the design basis flood event.
3.2.7.4 Lightning Strike Event Since the vertical concrete casks are located on an unsheltered pad, the casks may be subject to a lightning strike. A lightning strike on a concrete cask may be visually detected at the time of the strike, or by visible surface discoloration at the point of entry or exit of the current flow. There are no anticipated off-site radiological consequences due to the lightning event.
3.3 Security Event Events that impact the security of the ISFSI are discussed in the ISESI Security Plan.
These events represent a threat to the level of safety of the ISFSI due to unauthorized access, the introduction of threatening materials, or the use of hostile force in designated security areas. Security event detection and response is described in the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. The Emergency Plan may be implemented if necessary in response to a security event.
Events that fall into these areas will be categorized under the appropriate category in the classification process discussed in Section 4, CLASSIFICATION OF ACCIDENTS.
3.4 REV 7
4.0 CLASSIFICATION OF ACCIDENTS Based on NUJREG-l1140,"Regulatory Analysis of Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees", the NRC has determined that there are no credible design basis accidents that would exceed the EPA PAGs at an ISFSI Controlled Area boundary. Emergency classification guidance in Appendix F of Nuclear Energy Institute document NEI 99-01 (Final Rev. 4), "Methodology for Development of Emergency Action Levels," states, "The expectations of offsite response to an 'alert' classified under a 10 CFR 72.32 emergency plan are generally consistent with those for a notification of unusual event in a 10 CFR 50.47 emergency plan, i.e., to provide assistance if requested." The NEI 99-01 guidance is utilized in this plan to classify Maine Yankee ISFSI emergency events. The NRC Regulatory Analysis for Rev. 4 of Reg Guide 1.101 (Reference 5) to accept NET199-01 determined that the guidance in NE1 99-01 is appropriate for developing site specific EALs, to meet the intent of 10 CFR 50.47(b) (4) and Appendix F to Part 50.
Accidents and off-normal events that are analyzed for the ISFSI, including some events considered to be non-credible, have been reviewed and assigned a classification. There are no credible design basis accidents that would exceed the EPA PAGs at the ISFSI Controlled Area boundary. Table 4-1 summarizes events that are classified as an Unusual Event.
This plan classifies events based on predetermined Emergency Action Levels (EALs).
This approach provides a simple, predetermined response to an emergency event or accident, allowing a coordinated and phased approach to the eventual mitigation of the conditions and restoring the facility to a safe status.
4.1 Definitions 4.1.1 Unusual Event (U-E)
Events are in process or have occurred which indicate a potential degradation of the level of safety of the facility. No release of radioactive material requiring offsite response or monitoring is expected.
4.2 Categories of Events Per the Emergency Action Levels (EALs) guidance in NE1 99-01 (Reference 2), there are two categories of ISFSI events that can lead to an accident being classified as an Unusual Event (UF). The ISS/ED has the discretion to classify events based on the classification level definition. This discretion should be used when conditions or events are observed and no specific Initiating Condition (IC) / Emergency Action Level (EAL) is apparent.
The UBE classification will heighten awareness of the abnormal condition. Table 4-1 lists the initiating conditions, associated emergency action levels, and the applicable NRC emergency classification levels.
4.1 REV 7
4.2.1 Damage to a Loaded Vertical Concrete Cask That May Damage the Fuel or GTCC Confinement Boundary UE A UE classification for these IC/EALs is warranted on the basis of the occurrence of an event of sufficient magnitude that a loaded VCC is severely damaged, which may be indicative of potential damage to a cask confinement boundary. This classification includes events involving loss of a loaded fuel storage cask confinement boundary, leading to degradation of the fuel during storage or posing an operational safety problem with respect to removal of the degraded fuel confinement boundary from storage. Natural phenomena events and accident conditions in which a loaded VCC is damaged are classified at the UPE level. Cask seal integrity issues discovered during leakage testing associated with normal canister processing would be addressed in accordance with NAC technical specifications, or SAR* required actions, therefore, classification should not be made based on loss of seal integrity by itself. However, loss or potential loss of seal integrity coincident with an accident condition or natural phenomena that clearly affects the cask would justify a UPE classification. The 1SF SI vertical concrete storage casks are routinely monitored by site personnel such that any degradation would be detected.
Increases in radiation levels may be indicative of degradation of a storage cask.
4.2.2 Confirmed Security Event with Potential Loss of Level of Safety of the ISFSI LYE These IC/EALs provide a UE cl!assification for security events involving a potential loss of the level of safety of the ISFSI based on the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan.

5.0 EMERGENCY RESPONSE Emergency In the event ofResponse Overview an accident at the facility, actions will be taken by facility staff to report the event to the ISFSI Shift Supervisor (ISS) and to minimize the impact of the event. The primary objective of the initial responders is to assess the situation and minimize the risk imposed on workers and the general public. This involves initiation of required actions to mitigate a particular hazard. Subsequent actions include notifications, staff accountability, staff augmentation, and implementation of onsite corrective actions as necessary. The ISFSI Shift Supervisor becomes the Emergency Director (IS S/ED) upon classification and declaration of an unusual event.
5.1 Notification and Activation When an emergency condition is recognized, the event is classified and declared by the ISS/ED and mitigating actions are taken to minimize the progression of the event. These actions are initiated by available resources. The IS S/ED will request any offsite assistance that may be necessary due to the nature of the event. Following initial notifications, the Maine State Police (MSP) and the Nuclear Regulatory Commission (NRC) will be notified of the event and mitigating actions in progress or that have been completed.
Figure 5-1 depicts the initial .notification and activation process.
5.1.1 Maine Yankee Emergency Support Staff The ISS/ED or designee will direct ISFSI shift personnel to notify the ISFSI Support Staff of an event, if necessary. This will be accomplished by the commercial telephone system (i.e., land based, cell based, satellite based service). In the event the initiating conditions constitute a Security Event, these notifications will be made by the IS S/ED or designee. [
Notifications to supplement support positions should be completed within one hour of the event declaration.
5.1.2 Offsite Organizations Following notification of the Maine Yankee ISFSI Support Staff, the Maine State Police (MSP) will be contacted and provided pertinent information regarding the event, actions taken to mitigate the event and notification of any assistance which may be necessary from local organizations (i.e. fire, ambulance, police response). Notification to the MSP shall be comPleted within one hour of event declaration. Depending on the need for immediate outside assistance, these notifications may be initiated in an accelerated manner (i.e. immediate need for fire fighting capabilities or medical assistance). The MSP Headquarters Communications Center is staffed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day, 7 days a week. The MSP have the capability to contact State and county emergency response personnel, if needed.
The MSP will initiate notification to appropriate State Officials in the Maine Emergency Management Agency (MEMA), Division of Environmental Health (D)EH) and others as designated in the State's notification protocol, based on the event.
The NRC will be notified after the notification of the MSP and no later than one hour after the emergency was declared.
5.1 REV 7
5.1.3 Information to be Communicated A pre-scripted format is used to ensure consistent information is provided to the MSP and the NRC.
At a minimum, the following information will be provided during the initial notification of the event:
Event Classification; Date/Time of Classification; Reason or events causing the condition; General description of damage to major structures/areas; Personal injuries; Status of offsite assistance (fire/medical/other);
Name of person making notification; Date and Time of notification.
The information will be verified, via repeat-back, to ensure it was accurately communicated.
5.2 Radiological Assessment Initial response to an event will be to ascertain the cause, mitigate furter progression and determine the potential impact to ISFSI personnel and the general public. Initial assessment will normally consist of an area dose assessment if warranted. Initial dose assessment activities will be directed by the ISS/ED and performed by qualified personnel.
As soon as practical, facility staff should initiate general area radiation surveys to determine the actual extent of any radiological concern. Results of the surveys will' be analyzed by facility staff to formulate an action plan to mitigate the event and restore the facility to a safe condition. Survey data will also be used, as appropriate, in any on-site dose assessment techniques.
Following the termination of the event, environmental surveys (including, but not limited to water, soil, vegetation, etc.) may be required to determine the long-term impact of the event.
5.3 Protective Actions 5.3.1 Relocation and Accountability In an UNUSUAL EVENT declaration, personnel not directly involved with the response may be directed to relocate to an assembly area. Staff will be notified using the on-site paging system or other means. An assembly area may be established, based on the nature of the event, at a location determined by the ISS/ED. The ISFSI shift staff will maintain accountability of personnel and report any missing persons to the ISS/ED. Search and rescue efforts may be performed by shift personnel or local response personnel as necessary.
5.2 REV 7
5.3.2 First Aid/Medical Off-site emergency Response medical responders will be requested to report to the scene and initiate first aid treatment to stabilize the patient and prepare for transport to a medical facility. One or more First Aid kits are located in the facility. Injuries may be complicated by the presence of radiation and/or a contaminating substance (chemical or radiological). Given the design of the fuel/GTCC storage canisters, radiological contamination is unlikely, but should be evaluated. The patient will be assessed to
- determine if a life-threatening condition exists and appropriate actions taken to either contain or remove the contamination. In addition, environmental factors will be taken into account regarding the need to stabilize the patient in place or remove to a safer area (i.e. lower radiation levels, etc.). Maine Yankee maintains a Letter of Agreement with the Wiscasset Ambulance Service for transporting injured/contaminated workers from the site to a receiving hospital. In addition, agreements have been made with the Midcoast Hospital (Brunswick) for treating personnel with various types of injuries/conditions.
5.3.3 Personnel Monitoring Personnel working in known radiation areas will be issued dosimetry in accordance with existing radiation protection procedures. During emergency conditions, they normally retain their dosimetry and report to either their assigned emergency station or the assembly area, if a person suspects they may be contaminated, they will be monitored by Radiation Protection personnel.
Emergency support staff will be issued dosirnetry as required for assigned tasks.
Exposure control will be maintained in accordance with the site Radiation Protection and ALARA programs. Dose extensions may be granted in excess of the limits of 10OCFR20 for special circumstances. These extensions will be in accordance with EPA-400-R 001, Manual of Protective Action Guides and ProtectiveActions for Nuclear Incidents.
Extensions above the I0CFR_20 limits must be approved by the IS S/ED. The anticipated emergency exposures are well within the limits specified in Table 5-1.

equivalent from the internal exposures to non-pregnant adults from exposure and intake during an emergency situation. Dose limits to the eye should be 3 times the listed value.
Dose limits to any other organ (including skin and body extremities) should be 10 times the listed value.
5.3.4 Decontamination Capabilities Survey instrumentation for personnel frisking is available. Personnel contamination identified during the initial survey will require the contaminated individual to remove protective apparel, re-survey, and if skin contamination levels are identified, perform decontamination as directed by radiation protection personnel.
In the event that accident conditions result in a contaminated injured individual, the victim's rescue and medical treatment take precedence over the Victim's radiation exposure due to bodily contamination. Gross decontamination of the victim (generally limited to the removal of contaminated articles of clothing) will be accomplished to the extent that the health of the patient is not affected. Decontamination measures associated with wounds will be performed under the joint supervision of the attending physician at the hospital and the responding radiation protection representative.
5.3.5 Contamination and Hazard Exposure Control Surveys will be conducted to determine which areas contain contamination of either a radiological nature or a hazardous substance. These areas will be identified by either marking with boundary rope or tape and access will be limited and controlled accordingly by the radiation protection personnel. Monitoring of the area will be conducted using appropriate equipment, based on the type of contamination. All personnel required to work in the area will be provided appropriate personnel protective equipment (coveralls, booties, gloves, etc.) by the Radiation Protection contractor. The level of protection will be determined by the IS S/ED or other designated personnel.
5.4 REV"7
5.3.6 Emergency Action This plan permits emergency response personnel to take reasonable action that departs from a license condition or a technical specification in an emergency when this action is ilmmediately needed to protect the public health and safety and no action consistent with license conditions and technical specifications can provide adequate or equivalent protection is immediately apparent.
5.4 Coordination with Offsite Agencies There is no response required from State agencies. State government response is expected to be limited to recording the notification of the emergency, periodically receiving updated information on the emergency, and coordinating public information news releases. Upon request, Local government agencies (i.e. fire, police, ambulance) will respond to the ISFSJ during an emergency, if necessary.
If needed, provisions exist for limiting traffic on roads leading to the Maine Yankee site.
These actions would be coordinated through the Maine State Police or the Lincoln County Sheriffs Office, Wiscasset, Maine.

1.0 INTRODUCTION
Company's PowerYankee (MYAPC) plan This document to for responding describes the Maine emergencies that may ariseAtomic Yankee at the Maine Independent Spent Fuel Storage Installation (ISFSI). The overall purpose of the plan is to delineate the actions necessary to safeguard ISFSI personnel and minimize damage to site property in the event of an incident at the ISFSI. Analyses of the possible design basis events and consequences are presented in the Safety Analysis Report for the UMS Universal Storage System (NAC UMS SAR) used at the ISFSI for dry spent fuiel storage.
The analyses of the potential radiological impact of an accident at the Maine Yankee site indicates that any releases beyond the ISESI Controlled Area boundary are expected to be less than the U.S. Environmental Protection Agency (EPA) protective action guide (PAG) exposure levels, as detailed in EPA-400-R-92-001, Manual of Protective Action Guides and Protective Actions for Nuclear Incidents. Exposure levels which may warrant pre-planned response measures are generally limited to the Controlled Area. For this reason, radiological emergency planning is focused on the Controlled Area.

2.0 FACILITY DESCRIPTION 2.1 Maine Yankee Site 2.1.1 Overview The Maine Yankee site is located in the town of Wiscasset, Lincoln County, Maine. Site coordinates are approximately 43 degrees 57 minutes 5 seconds north latitude and 69 degrees 41 minutes 45 seconds west longitude. The site is bounded by the Back River on the east, mainland on the north and Bailey Cove on the west. The ISFSI is located on a peninsula known as Bailey Point, which extends south to Montsweag Bay (Figure 2-1).
The ISFSI facility is depicted on Figure 2-2. Spent nuclear fuel is in interim storage within the specified secure fuel storage area and will be monitored by the ISFSJ staff.
2.2 General Area Within 5 miles of the site, land use is largely rural residential, small businesses, summer houses, idle farmland and forest. Housing is scattered along principal roads and is concentrated only in the center of Wiscasset.
The waters of the Back River, Montsweag Bay and associated tributaries are tidal and open to boating, both commercial and recreational. Regulation of boating is the responsibility of the U.S. Coast Guard and the State of Maine. The primary type of boating in the Mon._tswe~ag B~ay - Back River is shallow draft Pleasure boats. With no commercial traffic in the area, there is essentially no hazard to the site from potential accidents with commercial barges or boats carrying hazardous, toxic or explosive materials.
Industrial activity within the general area of the JSFSJ is minimal. The largest industrial facility is the Bath Iron Works, a shipbuilding facility located on the Kennebec River approximately 7 miles southwest in the city of Bath.
The Wiscasset Municipal Airport is the nearest airport to the site and is located approximately one .mile northwest of the site. It consists of one runway (approximately 3,400 feet long by 75 feet wide). This runway is aligned such that takeoffs and landings are on headings of either 070 or 250 (the predominant heading is 250). The majorities of aircraft that are serviced by this facility are privately owned and are similar to the Piper Colt, Cherokee, and Cessna 150 and 172 type craft. The largest aircraftthat typically use the facility are similar to the Lear 25, Citation II and Rockwell Commander type craft.

2.3 Independent Spent Fuel Storage Installation (ISFSI)
The ISFSI is designed for interim storage of fuel for a minimum of 50 years in a contained shielded system. The ISFSI utilizes the Universal MPC System (UMSTM) developed by NAC International. The UMSTM is a canister-based multi-purpose canister (MPG) system designed for both storage and transportation of spent nuclear fuel. The canister-based spent fuel storage system is a passive system which utilizes an outer concrete cylinder called a Vertical Concrete Cask (VCC) to protect and shield the inner sealed metal canister. The VCC is vented for natural convection cooling and has no moving parts. Decay heat from the loaded fuel storage canister in the VCC is dissipated to the surrounding air by a once through buoyancy driven airflow. The VCC provides radiation shielding, as well as protection from tornado missiles and earthquakes.
The ISFST site consists of a Protected Area (PA) for fuel storage and a Security/Operations Building. The ISFSI has a Controlled Area that extends at least 300 meters from the nuclear fuel storage area.
The PA has sixteen concrete storage pads, and is surrounded by a security fence and a nuisance fence with an isolation zone between the two fences. A partial earthen berm is provided around the facility to reduce the visual impact of the facility. The ISFSI contains a total of 64 storage casks, with one sealed fuel canister per VCC. The types of canisters stored in the storage casks include 60 casks for spent fuel and 4 casks for Greater Than Class C (GTCC) waste. Sixteen storage pads of equal size are provided for uniformity, which allows for storage of 4 casks per storage pad. The ISFSI site is arranged to provide maneuvering room around the storage pads for access with a cask heavy haul tractor-trailer.
The Security/Operations Building provides offices and work space for the operating and maintenance personnel, including the Radiation Controls Checkpoint lunch/conference rooms, restrooms, locker rooms, document control room, spare parts storage, and a diesel generator for emergency power. The Security/Operations Building also houses the ISFSJ security staff, security equipment, and communications equipment. Access to the ISFSI protected area is controlled and monitored by the security staff.
The ISFSI operates under the provisions of a general license utilizing the UJMSTM spent fuel storage/transportation system. The UMSTM system is licensed under a Certificate of Compliance issued by the U.S. Nuclear Regulatory Commission (NRC) in accordance with 10 CFR Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel and High-Level Radioactive Waste".

3.0 ISFSI ACCIDENT TYPES. DETECTION AND CONSEQUENCES 3.1 Radiological Events There are no postulated credible ISFSI accident conditions that would impose a radiological hazard to personnel beyond the ISFSI Controlled Area boundary. There are no credible design basis accidents that would exceed the EPA PAGs at the ISESI Controlled Area boundary. In the event of an ISFSI accident condition, the associated radiological hazards are limited to personnel onsite at the time of the event.
The postulated ISFSI accident conditions are described in Chapter 11 of the Safety Analysis Report for the UMS Universal Storage System developed by NAC International (Reference 4).
3.2 Non-Radiological Events The spectrum ofIJSFSI non-radiological events that could necessitate implementation of this Emergency Plan is limited. These events fall into the category of general industrial incidents (e.g. fire, explosion, toxic material release, etc.), natural and destructive phenomena (hurricane, tornado, etc.) or security events. These events are further described in Chapter 11 of the Safety Analysis Report for the UMSUniversal Storage System. The determination of which, events are included is based on the probability of occurrence, the potential severity and the potential impact on the facility of the event.
3.2.1 Tip-Over of Vertical Concrete Cask A hypothetical non-credible accident condition has been postulated involving the non-mechanistic tip-over of a vertical concrete storage cask. Functionally, the cask is not expected to suffer significant adverse consequences due to this event. The concrete cask and canister are expected to continue providing design basis shielding, geometry control of contents, and contents confinement performance. The tipped-over configuration of the concrete cask will be obvious during a Site inspection following the initiating event.
There is an adverse localized radiological consequence due to the hypothetical tip-over event since the bottom end of the concrete cask has significantly less shielding than the sides and top of these same components. The estimated dose rate from the-bottom of a tipped-over cask is calculated to be approximately 34 rem/hr at 1 meter, 4 rem/hr at 4 meters, and < 10Omrem/hr at 100 meters (NAC-SAR). Following a tip-over event, supplemental shielding should be used until the concrete cask can be up-righted. Surface and top and bottom edges of the concrete cask are expected to exhibit cracking and possible loss of concrete down to the layer of reinforcing bar. The increased dose rate due to this cracking is not expected to be significant. There are no credible events expected to result in a cask tip-over.
3.1 REV 7
3.2.2 Tornado and Tornado Driven Missiles It is not expected that the performance of the UMS storage cask will be significantly affected by a tornado event. It is not anticipated that postulated tornado wind loading and missile impacts are capable of overturning a cask, or penetrating the cask concrete boundary and affecting the fuel storage canister. A tornado event can be visually observed. Advanced warning of a tornado and of tornado sightings may be received from the National Weather Service, local radio and television stations, local law enforcement personnel, and site personnel. An inspection of the cask exterior surface following a tornado event is required. The inspection should be directed at ensuring the inlets and outlets have not become blocked by wind-blown debris and checking for obvious concrete surface damage. Damage to the vertical concrete cask after a design basis tornado is not anticipated to result in radiation exposure at the Controlled Area boundary that would exceed the EPA PAGs exposure guidelines. The penetrating missile impact is estimated to reduce the concrete shielding thickness, locally at the point of impact, by approximately 6 inches. Localized cask surface dose rates for the removal of 6 inches of concrete are estimated to be less than 250 rnrem/hr (NAC SAR Section 11.2.11).
3.2.3 Explosions.
An explosion affecting the Universal Storage System may be caused by industrial accidents or the presence of explosive substances in the vicinity of the ISFSI. It is not anticipated that explosive substances will be stored or used at the JSFSJ. An explosion in the vicinity of the ISFSI would be sensed by on-duty ISFSJ personnel. In the event of a nearby explosion, an inspection of the concrete casks may be required to check cask integrity, to ensure that the air inlets and outlets are free of debris, and to ensure that the monitoring system and screens are intact. There are no anticipated off-site radiological consequences for this event.
3.2.4 Seismic Event The earthquake evaluation shows that the loaded or empty vertical concrete casks are not expected to tip over or slide in the event of an earthquake. Significant earthquakes would be detected by ground motion. Inspection of the vertical concrete casks is required following an earthquake event. The proper positioning of the Concrete casks should be verified to ensure they maintain the established spacing requirements. The temperature monitoring system should be checked for operation. There are no anticipated off-site radiological consequences for earthquake events.
3.2 REV 7
3.2.5 Fires There are no flammable materials routinely present in the ISFSI cask storage area. A "combustible liquid control zone" shall be established for the ISFSI itself, which shall be a minimum of 10 feet from the outside perimeter of the VCC. The total liquid combustibles allowed within the zone cannot exceed 50 gallons and must be in direct support of ISFSI operations or maintenance. A fire in the vicinity of the ISFSI will be detected by observation of the fire or smoke. Upon detection of a fire, appropriate actions should be taken by site personnel to report andlor extinguish the fire. The concrete cask should be inspected for general deterioration of the concrete, loss of shielding (spalling of concrete), exposed reinforcing bar, and surface discoloration that could affect heat rejection. This inspection serves as the basis for the determination of any repair activities necessary to return the concrete cask to its design basis configuration. There may be local spalling of concrete during the fire event, which could lead to some minor reduction in shielding effectiveness. The principal effect would be local increases in radiation dose rates on the cask surface. There are no off-site radiological consequences anticipated for this event.
3.2.6 Abnormal Cask Outlet Temperature Shift This event involves an abnormal outlet temperature shift caused by a partial or full blockage of the vertical concrete cask air inlets and outlets that could result in the heat up of the fuel cladding, the fuel basket and the concrete, with the temperature potentially reaching the design basis limiting temperature. Full blockage could result in these temperature limits potentially being exceeded after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Blockage of the cask air inlets and outlets will be detected by the Cask outlet temperature monitoring system. Any obstruction blocking the air inlets and outlets must be manually removed. There are no significant radiological consequences for this event at the Controlled Area boundary, as the vertical concrete cask is expected to retain its shielding performance (NAC SARL 11.2.13).
3.2.7 Other Conditions 3.2.7.1 Off-Normal Canister Handling Events These events would involve off-normal occurrences during the handling or transfer of a loaded transportable storage canister (TSC), i.e., during the installation or removal of the canister in or from the vertical concrete cask (VCC), or the transfer cask (TFR).
Unintended loads could be applied to the canister due to misalignment or faulty crane operation, or due to inattention of the operator. The event is expected to be obvious to the operators at the time of occurrence. There is no anticipated deterioration of the canister or fuel basket performance due to this event. There are no anticipated off-site radiological consequences associated with this off-normal event.
3.3 REV 7
3.2.7.2 Drop of Vertical Concrete Cask This event involves dropping a loaded vertical concrete cask during routine handling operations. This event may be due to the failure of one or more of the cask lifting jacks or of the air pad system. The maximum lift height shall be limited to less than 24 inches by administrative controls. The event would be detected by the operators as it occurs.
The damaged cask should be inspected and repaired prior to continued use. There are no anticipated off-site radiological consequences for this event.
3.2.7.3 Flood Event The UMS storage system vertical concrete casks have been evaluated for a design basis flood condition having a 50-foot depth of water and a water velocity of 15 feet per second. This flood depth would frully submerge the vertical concrete casks. The analysis shows that the vertical concrete casks are not expected to slide or overturn during the design basis flood. Small floods may lead to blockage of the concrete cask air inlet vents.
Partial and full blockage of air inlets is described in Section 3.2.6 of this plan. Flooding conditions would be detected by the ISFSI staff or personnel working in the vicinity of the ISFSI. A potential exists for collection of debris or accumulation of silt at the base ofo the cask, which could clog or obstruct the air inlet vents. Operation of the temperature monitoring system should be verified, as flood conditions may have impaired its,*
operation. There are no anticipated off-site radiological consequences associated with the design basis flood event.
3.2.7.4 Lightning Strike Event Since the vertical concrete casks are located on an unsheltered pad, the casks may be subject to a lightning strike. A lightning strike on a concrete cask may be visually detected at the time of the strike, or by visible surface discoloration at the point of entry or exit of the current flow. There are no anticipated off-site radiological consequences due to the lightning event.
3.3 Security Event Events that impact the security of the ISFSI are discussed in the ISESI Security Plan.
These events represent a threat to the level of safety of the ISFSI due to unauthorized access, the introduction of threatening materials, or the use of hostile force in designated security areas. Security event detection and response is described in the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan. The Emergency Plan may be implemented if necessary in response to a security event.
Events that fall into these areas will be categorized under the appropriate category in the classification process discussed in Section 4, CLASSIFICATION OF ACCIDENTS.
3.4 REV 7
4.0 CLASSIFICATION OF ACCIDENTS Based on NUJREG-l1140,"Regulatory Analysis of Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees", the NRC has determined that there are no credible design basis accidents that would exceed the EPA PAGs at an ISFSI Controlled Area boundary. Emergency classification guidance in Appendix F of Nuclear Energy Institute document NEI 99-01 (Final Rev. 4), "Methodology for Development of Emergency Action Levels," states, "The expectations of offsite response to an 'alert' classified under a 10 CFR 72.32 emergency plan are generally consistent with those for a notification of unusual event in a 10 CFR 50.47 emergency plan, i.e., to provide assistance if requested." The NEI 99-01 guidance is utilized in this plan to classify Maine Yankee ISFSI emergency events. The NRC Regulatory Analysis for Rev. 4 of Reg Guide 1.101 (Reference 5) to accept NET199-01 determined that the guidance in NE1 99-01 is appropriate for developing site specific EALs, to meet the intent of 10 CFR 50.47(b) (4) and Appendix F to Part 50.
Accidents and off-normal events that are analyzed for the ISFSI, including some events considered to be non-credible, have been reviewed and assigned a classification. There are no credible design basis accidents that would exceed the EPA PAGs at the ISFSI Controlled Area boundary. Table 4-1 summarizes events that are classified as an Unusual Event.
This plan classifies events based on predetermined Emergency Action Levels (EALs).
This approach provides a simple, predetermined response to an emergency event or accident, allowing a coordinated and phased approach to the eventual mitigation of the conditions and restoring the facility to a safe status.
4.1 Definitions 4.1.1 Unusual Event (U-E)
Events are in process or have occurred which indicate a potential degradation of the level of safety of the facility. No release of radioactive material requiring offsite response or monitoring is expected.
4.2 Categories of Events Per the Emergency Action Levels (EALs) guidance in NE1 99-01 (Reference 2), there are two categories of ISFSI events that can lead to an accident being classified as an Unusual Event (UF). The ISS/ED has the discretion to classify events based on the classification level definition. This discretion should be used when conditions or events are observed and no specific Initiating Condition (IC) / Emergency Action Level (EAL) is apparent.
The UBE classification will heighten awareness of the abnormal condition. Table 4-1 lists the initiating conditions, associated emergency action levels, and the applicable NRC emergency classification levels.
4.1 REV 7
4.2.1 Damage to a Loaded Vertical Concrete Cask That May Damage the Fuel or GTCC Confinement Boundary UE A UE classification for these IC/EALs is warranted on the basis of the occurrence of an event of sufficient magnitude that a loaded VCC is severely damaged, which may be indicative of potential damage to a cask confinement boundary. This classification includes events involving loss of a loaded fuel storage cask confinement boundary, leading to degradation of the fuel during storage or posing an operational safety problem with respect to removal of the degraded fuel confinement boundary from storage. Natural phenomena events and accident conditions in which a loaded VCC is damaged are classified at the UPE level. Cask seal integrity issues discovered during leakage testing associated with normal canister processing would be addressed in accordance with NAC technical specifications, or SAR* required actions, therefore, classification should not be made based on loss of seal integrity by itself. However, loss or potential loss of seal integrity coincident with an accident condition or natural phenomena that clearly affects the cask would justify a UPE classification. The 1SF SI vertical concrete storage casks are routinely monitored by site personnel such that any degradation would be detected.
Increases in radiation levels may be indicative of degradation of a storage cask.
4.2.2 Confirmed Security Event with Potential Loss of Level of Safety of the ISFSI LYE These IC/EALs provide a UE cl!assification for security events involving a potential loss of the level of safety of the ISFSI based on the Maine Yankee Independent Spent Fuel Storage Installation Physical Security Plan.

5.0 EMERGENCY RESPONSE Emergency In the event ofResponse Overview an accident at the facility, actions will be taken by facility staff to report the event to the ISFSI Shift Supervisor (ISS) and to minimize the impact of the event. The primary objective of the initial responders is to assess the situation and minimize the risk imposed on workers and the general public. This involves initiation of required actions to mitigate a particular hazard. Subsequent actions include notifications, staff accountability, staff augmentation, and implementation of onsite corrective actions as necessary. The ISFSI Shift Supervisor becomes the Emergency Director (IS S/ED) upon classification and declaration of an unusual event.
5.1 Notification and Activation When an emergency condition is recognized, the event is classified and declared by the ISS/ED and mitigating actions are taken to minimize the progression of the event. These actions are initiated by available resources. The IS S/ED will request any offsite assistance that may be necessary due to the nature of the event. Following initial notifications, the Maine State Police (MSP) and the Nuclear Regulatory Commission (NRC) will be notified of the event and mitigating actions in progress or that have been completed.
Figure 5-1 depicts the initial .notification and activation process.
5.1.1 Maine Yankee Emergency Support Staff The ISS/ED or designee will direct ISFSI shift personnel to notify the ISFSI Support Staff of an event, if necessary. This will be accomplished by the commercial telephone system (i.e., land based, cell based, satellite based service). In the event the initiating conditions constitute a Security Event, these notifications will be made by the IS S/ED or designee. [
Notifications to supplement support positions should be completed within one hour of the event declaration.
5.1.2 Offsite Organizations Following notification of the Maine Yankee ISFSI Support Staff, the Maine State Police (MSP) will be contacted and provided pertinent information regarding the event, actions taken to mitigate the event and notification of any assistance which may be necessary from local organizations (i.e. fire, ambulance, police response). Notification to the MSP shall be comPleted within one hour of event declaration. Depending on the need for immediate outside assistance, these notifications may be initiated in an accelerated manner (i.e. immediate need for fire fighting capabilities or medical assistance). The MSP Headquarters Communications Center is staffed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day, 7 days a week. The MSP have the capability to contact State and county emergency response personnel, if needed.
The MSP will initiate notification to appropriate State Officials in the Maine Emergency Management Agency (MEMA), Division of Environmental Health (D)EH) and others as designated in the State's notification protocol, based on the event.
The NRC will be notified after the notification of the MSP and no later than one hour after the emergency was declared.
5.1 REV 7
5.1.3 Information to be Communicated A pre-scripted format is used to ensure consistent information is provided to the MSP and the NRC.
At a minimum, the following information will be provided during the initial notification of the event:
Event Classification; Date/Time of Classification; Reason or events causing the condition; General description of damage to major structures/areas; Personal injuries; Status of offsite assistance (fire/medical/other);
Name of person making notification; Date and Time of notification.
The information will be verified, via repeat-back, to ensure it was accurately communicated.
5.2 Radiological Assessment Initial response to an event will be to ascertain the cause, mitigate furter progression and determine the potential impact to ISFSI personnel and the general public. Initial assessment will normally consist of an area dose assessment if warranted. Initial dose assessment activities will be directed by the ISS/ED and performed by qualified personnel.
As soon as practical, facility staff should initiate general area radiation surveys to determine the actual extent of any radiological concern. Results of the surveys will' be analyzed by facility staff to formulate an action plan to mitigate the event and restore the facility to a safe condition. Survey data will also be used, as appropriate, in any on-site dose assessment techniques.
Following the termination of the event, environmental surveys (including, but not limited to water, soil, vegetation, etc.) may be required to determine the long-term impact of the event.
5.3 Protective Actions 5.3.1 Relocation and Accountability In an UNUSUAL EVENT declaration, personnel not directly involved with the response may be directed to relocate to an assembly area. Staff will be notified using the on-site paging system or other means. An assembly area may be established, based on the nature of the event, at a location determined by the ISS/ED. The ISFSI shift staff will maintain accountability of personnel and report any missing persons to the ISS/ED. Search and rescue efforts may be performed by shift personnel or local response personnel as necessary.
5.2 REV 7
5.3.2 First Aid/Medical Off-site emergency Response medical responders will be requested to report to the scene and initiate first aid treatment to stabilize the patient and prepare for transport to a medical facility. One or more First Aid kits are located in the facility. Injuries may be complicated by the presence of radiation and/or a contaminating substance (chemical or radiological). Given the design of the fuel/GTCC storage canisters, radiological contamination is unlikely, but should be evaluated. The patient will be assessed to
- determine if a life-threatening condition exists and appropriate actions taken to either contain or remove the contamination. In addition, environmental factors will be taken into account regarding the need to stabilize the patient in place or remove to a safer area (i.e. lower radiation levels, etc.). Maine Yankee maintains a Letter of Agreement with the Wiscasset Ambulance Service for transporting injured/contaminated workers from the site to a receiving hospital. In addition, agreements have been made with the Midcoast Hospital (Brunswick) for treating personnel with various types of injuries/conditions.
5.3.3 Personnel Monitoring Personnel working in known radiation areas will be issued dosimetry in accordance with existing radiation protection procedures. During emergency conditions, they normally retain their dosimetry and report to either their assigned emergency station or the assembly area, if a person suspects they may be contaminated, they will be monitored by Radiation Protection personnel.
Emergency support staff will be issued dosirnetry as required for assigned tasks.
Exposure control will be maintained in accordance with the site Radiation Protection and ALARA programs. Dose extensions may be granted in excess of the limits of 10OCFR20 for special circumstances. These extensions will be in accordance with EPA-400-R 001, Manual of Protective Action Guides and ProtectiveActions for Nuclear Incidents.
Extensions above the I0CFR_20 limits must be approved by the IS S/ED. The anticipated emergency exposures are well within the limits specified in Table 5-1.

In the event that accident conditions result in a contaminated injured individual, the victim's rescue and medical treatment take precedence over the Victim's radiation exposure due to bodily contamination. Gross decontamination of the victim (generally limited to the removal of contaminated articles of clothing) will be accomplished to the extent that the health of the patient is not affected. Decontamination measures associated with wounds will be performed under the joint supervision of the attending physician at the hospital and the responding radiation protection representative.
5.3.5 Contamination and Hazard Exposure Control Surveys will be conducted to determine which areas contain contamination of either a radiological nature or a hazardous substance. These areas will be identified by either marking with boundary rope or tape and access will be limited and controlled accordingly by the radiation protection personnel. Monitoring of the area will be conducted using appropriate equipment, based on the type of contamination. All personnel required to work in the area will be provided appropriate personnel protective equipment (coveralls, booties, gloves, etc.) by the Radiation Protection contractor. The level of protection will be determined by the IS S/ED or other designated personnel.

5.3.6 Emergency Action This plan permits emergency response personnel to take reasonable action that departs from a license condition or a technical specification in an emergency when this action is ilmmediately needed to protect the public health and safety and no action consistent with license conditions and technical specifications can provide adequate or equivalent protection is immediately apparent.
5.4 Coordination with Offsite Agencies There is no response required from State agencies. State government response is expected to be limited to recording the notification of the emergency, periodically receiving updated information on the emergency, and coordinating public information news releases. Upon request, Local government agencies (i.e. fire, police, ambulance) will respond to the ISFSJ during an emergency, if necessary.
If needed, provisions exist for limiting traffic on roads leading to the Maine Yankee site.
These actions would be coordinated through the Maine State Police or the Lincoln County Sheriffs Office, Wiscasset, Maine.
