ATTACHMENT 1 10 CFR 50.54(g)(5) Procedure Change Summary Analysis Docket Nos. 50-289 and 50-320 Page 1 of 2 Attachment 1 10 CFR 50.54(g}(5) Procedure Change Summary Analysis Document Title The following Exelon Generation Company, LLC (EGC) Emergency Plan Annex revision is provided for Three Mile Island Nuclear Station {TMI):

• EP-AA-1009, Revision 27, "Exelon Nuclear Radiological Emergency Plan Annex for Three Mile Island (TM/) Station" Description of Procedure The TMI Emergency Plan Annex (i.e., EP-AA-1009) contains emergency planning information and guidance unique to the station. This includes facility geography, emergency response facility locations, and process and radiation monitoring instrumentation that provides a description of the station's emergency response capabilities, as well as any station unique commitments.

In conjunction with EP-AA-1009, EGC maintains a Nuclear Standardized Radiological Emergency Plan (i.e., EP-M-1000) that outlines the basis for the response actions that would be implemented during an emergency. The planning efforts common to all EGC nuclear stations are encompassed within the Standard Plan.

Description of Changes This revision to EP-AA-1009 addresses the transition of the TMI Nuclear Accident Reporting System (NARS) lines to the EMnet system. The regulatory guidance described in NUREG-0654 requires that licensees establish reliable primary and backup means of communication.

Additionally, NUREG-0696 requires that licensees provide a means for Emergency Response Facilities (ERFs) to have telephone access to commercial telephone common-carrier services that bypass any onsite or local offsite telephone switching facilities that may be susceptible to a loss of power during emergencies.

The TMI Emergency Plan Annex (EP-AA-1009) describes the station's telephone systems in Section 5.5.2. The communications systems described include the Emergency Preparedness (EP) Private Branch Exchange (PBX) system for emergency communications, the Site (OPX)

PBX systems, the Corporate PBX system for NRC telephones, and the Maintenance and Instrumentation telephone system.

Specifically, the EP PBX NARS system is used in the Main Control Room (MCR), Technical Support Center {TSC), and Emergency Operations Facility (EOF) to support communication to the States and counties that are required to be notified during a nuclear emergency. The NARS system links together the station's MCR, EOF, TSC, and State and local authorities as appropriate.

Docket Nos. 50-289 and 50-320 Page 2 of 2 Description of How the Changes Still Comply with Regulations The existing NARS system for TMI utilizes copper wiring leaving each phone and traveling to a plant PBX Room and through a switch that is separate and redundant from the switch used for normal PBX communications. The calls are also similarly routed to each required agency in the multi-call ring.

TMI is transitioning the current dedicated NARS phone system to the EMnet system, a Voice over Internet Protocol (VoIP) system with satellite telephone back-up. The VoIP system utilizes phones with two separate network paths to access the call managers at the service provider's data centers. The primary network connection for communications will be through the business Local Area Network (LAN) and out to the internet. The LAN path used by the EMnet system is separate and redundant from the commercial phone system switch used to route normal phone communications. Additionally, to ensure the security of the system, all network sockets must be registered with the call managers at service provider's facilities. This allows for firewall rules that are outbound only. In the event of a network failure, the system will automatically fail over to the secondary network connection on an established and dedicated satellite network link to achieve a communications path with the designated emergency facilities and agencies. This second communication path utilizes the same security features and is also protected by a firewall device. The EMnet system (both the LAN and satellite portions) are continuously and remotely analyzed to determine operational status. The current system/technology for the NARS phone system will be decommissioned, but a back-up notification path for notifications will remain available through the commercial phone system.

Description of Why the Changes are Not a Reduction in Effectiveness (RIE)

The Emergency Plan in this revision continues to satisfy the applicable regulatory requirements established in 10 CFR 50.47, 10 CFR 50, Appendix E, and the guidance described in NUREG-0654 and NUREG-0696. Regulatory commitments continue to be met as a result of the changes. The changes do not alter the capability of the Emergency Response Organization (ERO) to implement required Emergency Plan functions, and do not affect the timeliness of the performance of these functions. Therefore, the changes made to EP-AA-1009 in Revision 27 do not constitute a reduction in effectiveness of the Emergency Plan for TMI.

Three Mile Island Station Annex Exelon Nuclear Section 1: Introduction

• As required in the conditions set forth by the Nuclear Regulatory Commission (NRC) for the operating licenses for the Exelon Nuclear Stations, the management of Exelon recognizes its responsibility and authority to operate and maintain the nuclear power stations in such a manner as to provide for the safety of the general public.

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

This document serves as the Three Mile Island Station (TMI) Annex and contains information and guidance that is unique to the station. This includes on-shift staffing and augmentation, and facility geography and location which may differ from that contained under the Standard Plan. The Station Annex is subject to the same review and audit requirements as the Standard Plan.

1.1 Facility Description TMI Unit 1 is operated by Exelon Nuclear. The TMI Unit #1 is an 870 Mwe, pressurized water-type, nuclear steam supply system supplied by Babcock &

Wilcox Company .

• TMI Unit 2 is owned by First Energy Corporation. The TMI Unit 2 reactor was damaged during an accident in 1979 and is currently defueled and the plant maintained in long-term monitored storage. Monitoring of this facility is performed by Exelon Nuclear through a service agreement with First Energy Corporation.

The arrangement of the major TMl-1 and TMl-2 facilities is shown in Figures TMI 1-1 and TMI 1-2.

TMI Station is located in an area of low population density about 12 miles southeast of Harrisburg, Pennsylvania.

The area is in Londonderry Township, Dauphin County, about 2.5 miles from the southern tip of Dauphin County, where the county is coterminous with York and Lancaster Counties.

The TMI site is part of an 814-acre tract consisting of TMI and several adjacent islands, which were purchased by a predecessor. The island, *which is situated about 900 feet from the east bank and approximately one mile from the west bank of the Susquehanna River, is elongated parallel to the flow of the river with its longest axis oriented approximately due north and south. The north and south ends of the island have access bridges, which connect the island to State Highway Route 441. The north access bridge is used daily.* Route 441 is a two-lane highway, which runs parallel to TMI on the east bank of the Susquehanna River and is more than 2,000 feet from the TMI reactors at the closest point.

November 2017 TMI 1-1 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear A Norfolk Southern one-track line runs adjacent and parallel to Route 441 on the east bank of the river. On the west bank of the river, there is a multi-track Norfolk Southern line at the river's edge about 1.25 miles west of the site and a black top, two lane road that runs parallel to it. There is a one-track railroad spur across the bridge on the north end of the island, which is used for site-related activities. A general area map showing the relative location of the TMI sites is shown as Figure TMI 1-2.

In addition to the information listed above, specific details concerning the TMI Site are included in the Updated Final Safety Analysis Report (UFSAR).

1.2 Emergency Planning Zones TMI has taken into consideration the information and data presented above, guidance provided by the Environmental Protection Agency (EPA), NRG and the Pennsylvania Emergency Management Agency (PEMA), as well as other important factors such as organizational capabilities, availability of emergency facilities and equipment, and the methods for implementing the Emergency Plan in defining the Emergency Planning Zones (EPZs) for the TMI. As a result, an EPZ having an approximate radial distance of 10 miles from the site has been. defined as the "Plume Exposure Pathway". An EPZ having a radial distance of 50 miles from the site has been defined as the "Ingestion Exposure Pathway".

Figure TMI 1-4 illustrates the respective boundaries of for the Plume Exposure and Ingestion Pathways .

• 1.2.1 Owner Controlled Area, Exclusion Area and Low Population Zone

1. The Owner Controlled Area for the TMI site includes all areas within the perimeter security fence. The minimum distance to the owner controlled area boundary is measured from the centerline of the Fuel Handling Building to the western shoreline of the island, which is approximately 675 feet.

2. The Exclusion Area for the TMI site is a 2,000 foot radius that includes a portion of TMI, the river surface around it, and a portion of Shelly Island. The minimum distance of 2,000 feet occurs on the shore of the mainland in a due easterly direction. The TMl-1 licensee retains complete authority to determine and maintain sufficient control of all activities including the authority to exclude or remove personnel and property for all land areas within the exclusion area. A map showing the exclusion area boundary is included as Figure TMI 1-3. For the purposes of Emergency Planning, the exclusion area boundary and the site boundary are considered the same.

3. The Low Population Zone (LPZ) has a minimum distance of 2 miles to its outer boundary. The area of the Low Population Zone is also shown in Figure TMI 1-3 .

November 2017 TMI 1-2 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear 1.2.2 Population and Population Distribution

• • As previously discussed, LPZ has been defined with a minimum distance of 2 miles from its outer boundary to the TMI site. The nearest major population center is Harrisburg, Pennsylvania which is located approximately 12 miles northwest of TMI. This distance satisfies the requirements of 10 CFR 100 with respect to population center distance.

The population of residential areas, typical enrollment in various schools, and the hospital patient capacity in the surrounding area can be found in the TMI Evacuation Time Estimate (ETE) Study.

Within the two-mile LPZ, there are no schools. There are several recreational areas (Falmouth Fish Commission Access Area, Tri-County Boat Club and Canal Lock Boat Launch Area). There is some seasonal shift in population within a 5-mile radius of TMI since there are over 100 summer cabins on the islands within the area. Additional transients participate in boating activities in the vicinity of TMI.

1.2.3 Local Industrial and Military Facilities The TMI site is currently surrounded by farmlands within a 10-mile radius.

Lands are used for dairy cattle, tobacco, poultry, vegetables, fruit, corn, wheat, and other products. A summary of land use for the risk counties is provided in Table 1 and the FSAR. The Susquehanna River is used for sport fishing and boating but is not used for commercial fishing.

• Manufacturing industries in the region produce clothing, wood products, shoes, electrical wiring devices, steel products, packed meat and other food. These activities, within a 10-mile radius of the site, are confined chiefly to the communities of Harrisburg, New Cumberland, Steelton, and Middletown. A listing of typical industries within 10 miles of TMI can be found in the site Updated Final Safety Analysis Report (UFSAR). There are gas and oil transmission lines located at a minimum distance of approximately 2 miles from TMI .

• November 2017 TMI 1-3 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear Approximately 3 miles downstream from the site is the York Haven hydro-electric project. The York Haven Station is operated . on a "run-of-the-river" basis, and its power output is dependent primarily upon the water available. The reservoir is used for peaking operation during periods of low river flow. Brunner Island Station, a large steam-electric generating plant owned by the Pennsylvania Power & Light Company is located on the Susquehanna River approximately one mile downstream from the York Haven project. This station uses water from the river on a "once-through" basis for cooling water. Three other hydroelectric generating stations are also locat~d downstream from TMI, with each project having a dam and reservoir on the Susquehanna River. The three stations are Safe Harbor, Holtwood, and Conowingo Hydroelectric Projects, located approximately 25, 31, and 47 miles south of TMI, respectively.

There is also a coal fired, steam electric plant at Holtwood, and the Muddy Run Pumped Storage Project is associated with Conowingo Station. The Peach Bottom Atomic Power Station (PBAPS) is located along the west bank of the Susquehanna River, about 41 miles downstream of TMI, just north of the Maryland-Pennsylvania border and is the only nuclear plant within a 50-mile radius of TMI.

There are two airports within 10 miles of the TMI sites. Harrisburg International Airport- (formerly Olmsted Air Force Base) is located on the east bank of the Susquehanna River approximately 2.5 miles northwest of the site. The Capital City Airport is located approximately 8 miles west-northwest of TMI. The vital areas of the TMI sites are designed to withstand a hypothetical aircraft accident.

Norfolk Southern lines are located on both sides of the Susquehanna River, the closest being the east bank, approximately 2,000 feet from the TMI Reactor Buildings. Routine traffic in liquified petroleum gas was identified on the railroad line, which passes along the east shore of the river.

Analyses indicate that any missiles generated by this traffic would be less damaging than the postulated aircraft strike against which the plant is protected and that flammable gases would dissipate before reaching the TMI Nuclear Units.

The closest military installation to the site is the Air National Guard facility at Harrisburg International Airport. There are no military firing ranges or missile facilities within a 10-mile radius of TMI. Other military facilities, however, are Army and Navy depots located at New Cumberland and Mechanicsburg, Pennsylvania, respectively .

Three Mile Island Station Annex Exelon Nuclear 1.3 Participating Governmental Agencies The Exelon Nuclear Radiological Emergency Plan (REP) Annex for TMI Station TMI Emergency Plan was developed in coordination with the Commonwealth of Pennsylvania Emergency plan. In addition, specific State requirements for reporting of emergencies, providing information and data, and recommending protective actions, have been integrated directly into the Emergency Plan Implementing Procedures. In considering the Plume Expo~ure Pathway, there are also county plans that have been considered in the development of the REP Annex for TMI Station. The State Plan designates PEMA as the lead state agency for radiological emergency response planning and the state agency through which the Governor will exercise coordination and control during emergency. The State Plan is an integrated document setting forth the resources and responsibilities of all relevant state agencies. Significant plans from the State Departments of Agriculture, Environmental Resources, Bureau of Radiation Protection (BRP) are included in the State Plan.

1.3.1 Federal Agencies A summary of Federal response agencies, responsibilities and activities, as described under the National Response Framework (NRF), is contained in the Standard Plan. Specifics related to support for TMI Station are listed below.

1. The Department of the Army (local Ordinance Detachment) will

• provide an Explosive Ordinance Disposal capability in response to requests for assistance in the event of a bomb threat.

2. The Federal Aviation Administration (FAA) will ensure air traffic is diverted in the event of an emergency situation with a potential for radioactive release.

3. National Weather Service (NWS) will provide backup meteorological information upon request.

1.3.2 State Agencies The planning for, and response to a radiological emergency at the TMI site is the joint responsibility of TMI and the state/county/local governmental agencies. TMI is responsible for onsite emergency response. In order to fulfill this responsibility, TMI relies on various offsite agencies, both governmental and private, to provide assistance beyond that available onsite. The Commonwealth of Pennsylvania, through the various state, county and local agencies, is responsible for offsite emergency response.

In order to fulfill this responsibility, the state relies on TMI to provide necessary information on plant status and radiation releases. Recognizing the joint nature of their responsibilities, TMI and the relevant governmental agencies have coordinated their emergency planning and have provided for adequate and redundant communication systems to coordinate their response during an emergency event.

Three Mile Island Station Annex Exelon Nuclear

1. Pennsylvania Emergency Management Agency (PEMA)

PEMA is responsible to coordinate emergency services in the Commonwealth of Pennsylvania. Should a radiological emergency occur at the TMI site that requires the implementation of state, county, and local government radiological emergency response plans, the state agency through which the Governor will exercise coordination/control will be PEMA. However, as in all emergencies, the Governor retains directional control. The State role is further defined in the State Disaster Operations Plan - Annex E.

PEMA exercises authority over all non-licensee offsite organizations, who are a part of the emergency response team in the TMI Plume Exposure and Ingestion Pathways. This authority is based on the provisions of Section 7313 of the State of Pennsylvania Emergency Management Services Code 35 PA (C.S.A. Sections 7101-7707) also referred to as Pamphlet Law 1332. By law, PEMA is authorized to:

• Provide emergency direction and control of Commonwealth of Pennsylvania and local disaster emergency operations.

• Accept aid and coordinate assistance provided by Federal Agencies under provisions of the Federal Disaster Relief Act of 1974.

2. Department of Environmental Protection

• The Department of Environmental Protection (DEP), under the administration and technical direction of the Secretary, is responsible for gathering and evaluating technical information and for supplying such information and technical advice and recommendations to PEMA and the Pennsylvania Emergency Management Council.

Within the DEP, the Bureau of Radiation Protection (BRP) has been delegated responsibility for radiological emergencies. Specific responsibilities assigned to the DEP/BRP that are appropriate to radiological emergencies are defined in the State Plan. To provide for emergency response capability, the BRP has made provisions for 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day interface with PEMA.

• November 2017 TMI 1-6 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear 1.3.3 County Agencies Pamphlet Law 1332 states that, "each political subdivision of this Commonwealth is directed and authorized to establish a local emergency management organization in accordance with the plan and program of the PEMA. Each local organization shall have responsibility for emergency management, response and recovery within the territorial limits of the political subdivision within which it is organized and, in addition, shall conduct such services outside of its jurisdictional limits as may be required under this part." Therefore, each County and Local Emergency Management Coordinator in the State is responsible for establishing an emergency management organization within their respective jurisdiction, developing plans and preparing for emergency operations ..

With respect to the TMI Plume Exposure Pathway, Dauphin, York, Cumberland, Lancaster and Lebanon Counties have prepared Radiological Emergency Response Plans that are coordinated with both the State's Disaster Operations Plan and the REP Annex for TMI Station. Local government plans are either included directly within the respective County plan or are maintained as separate, but coordinated documents. The county Emergency Operations Centers (EOCs) are the location of the County dispatcher for police, fire, rescue and emergency medical services and is manned by dispatchers on a 24-hour basis. In the event of a PEMA communications breakdown, Dauphin County will act as the primary Communicator with PEMA, BRP, and the other four risk counties .

1.3.4 Additional Support Agencies The nature of an emergency may require augmenting the emergency organizations with assistance from additional personnel and organizations.

In order to ensure that support from local law enforcement, fire departments, hospitals, ambulance services and other organizations will be available on relatively short notice, agreements have been established with personnel and organizations. Agreements from offsite individuals, groups and agencies that support Three Mile Island may take one of the following forms:

• Contracts

• Letters of Agreement

• Memoranda of Understanding

• Formal Emergency Plans Refer to Appendix 2 for a listing of offsite support organizations .

As such, the State Environs Communicator position, listed under the Standard Plan, is not staffed at the Coatesville EOF. Rather the EOF Environmental Coordinator will interface directly with State representatives present in the EOF.

An Operations Assistant has been added to augment EOF staffing and provide TMI specific Operations knowledge in support of the existing

• Technical Support Manager and Operations Advisor positions .

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

No changes in augmentation positions or staffing levels for the Joint Information Center (JIC)) and Emergency News Center (ENC) from that specified in the Exelon Nuclear Standardized Radiological Emergency Plan.

2.3 Emergency Response Organization (ERO) Training Training is conducted in accordance with Section 0.5 of the -Exelon Nuclear Radiological Emergency Plan per TQ-AA-113, "ERO Training and Qualification."

Retraining is performed on an annual basis, which is defined as once per calendar year not to exceed 18 months between training sessions.

TMI will offer training for hospital personnel, and ambulance and rescue, police and fire departments required to* support implementation of the TMI Emergency Plan. This training shall include the procedures for notification, basic radiation protection and their expected roles. For those support organizations that must enter the site, training shall also include site access procedures and the identity (by ,title) of the individual in the site emergency organization who will control the organization's support activities .

Three Mile Island Station Annex Exelon Nuclear 2.4 Non-Exelon Nuclear Support Groups The nature of an emergency may require augmenting the emergency

• organizations with assistance from additional personnel and organizations. In order to ensure that support from local law enforcement, fire departments, hospitals, ambulance services and other organizations will be available on relatively short notice, agreements have been established with personnel and organizations. Agreements from offsite individuals, groups and agencies that support TMI may take one of the following forms:

• Contracts

• Letters of Agreement

• Memoranda of Understanding

• Formal Emergency Plans Refer to Appendix 2 for a listing of these support organizations.

2.4.1 Miscellaneous Organizations

• Other utilities

• Institute for Nuclear Power Operations (INPO)

• American Nuclear Insurers (ANI)

• AREVA

• Aviation services

• 2.4.2 Norfolk Southern Railroad Company The Norfolk Southern Railway track crosses the access to the facility, and impeding site access could impact the implementation of time sensitive emergency actions. Theses emergency actions include augmentation of the Emergency Response Organization, use of off-site assistance, and evacuation of non-essential personnel. Therefore, a Memorandum Of Understanding (MOU) has been established with Norfolk Southern Railway Company. The purpose of the MOU is to ensure that stopped or disabled train traffic does not impede access to the island across the North Bridge for the duration of the emergency. This will provide reasonable assurances that there is sufficient time to allow implementation of emergency actions at TMI in the event of a declared emergency. The MOU with Norfolk Southern Railway Company will be reviewed every five years .

• November 2017 TMI 4-2 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear 4.2 Assessment Actions

• The effluent radiation monitoring system provides indications of gross releases of gaseous and liquid radioactivity. .By applying C!3libration factors, meteorological data, or river flow, the gross indications are used to calculate

• approximate release rates in µCi/sec and dose rates at specific distances along the release pathways. Particulate and iodine analysis depends on collecting installed filter papers and charcoal cartridges for analysis in the counting room.

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

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

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

Portable monitoring instruments and sampling equipment consist of such items that are utilized and maintained on-site for normal day-to-day plant operations and are thus available for emergency use.

Refer to Section 5.2 of the REP Annex for TMI Station for a listing of assessment resources.

4.2.1 Radiological Assessment and Offsite Monitoring For the emergency assessment of gaseous releases, refer to the description of the dose projection model contained in Part II, Section 1.4 of the Standard Plan.

For liquid releases, the radionuclide concentration at any downstream location is determined by taking liquid effluent concentrations and applying the effluent flow rate and volumetric flow rate of the receiving water. Downstream users will be notified to curtail intake if the projected concentration is above the level specified in the procedures.

4.2.2 Source Term Determination Should the effluent radiation monitors be off-scale or otherwise inoperable, assessment of releases and off-site exposure would be made using the containment monitor readings, point of release grab samples, and pathway samples .

• November 2017 TMI 4-3 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear A detailed core damage assessment methodology has been established under Section 6.0 of the TMI Technical Support Center Calculation Guides. The process used is based on measured physical and chemical parameters that occur in the plant when the core is damaged. Three (3) methods have been developed under Section 6.0 of the TMI Technical Support Center Calculation Guides (per TOR 431) to determine core damage estimates:

1. In-core thermocouple temperature correlations to fuel conditions;

2. Radiation monitor and hydrogen production correlations based on fuel and plant system conditions; and

3. Chemical measurement correlations based on radionuclide inventory released into reactor coolant during core damage.

Throughout each emergency situation, continuing assessment will occur.

Assessment actions at Three Mile Island Station may include an evaluation of plant conditions; in-plant, onsite, and initial offsite radiological measurements; and initial estimates of offsite doses. Core damage information is used to refine dose assessments and confirm or extend initial protective action recommendations. Three Mile Island Station utilizes WCAP-14696-A, Revision 1, (1999) as the basis for this methodology of post-accident core damage assessment. This

• 4.3 methodology utilizes real-time plant indications. In addition, Three Mile Island Station may use samples of plant fluids and atmospheres as inputs to the CDAM (Core Damage Assessment Methodology) program for core damage estimation.

Protective Actions for the Offsite Public The responsibility for actions to protect persons in offsite areas rests *with the State and is described in detail in the State Emergency Plan and implemented in conjunction with the county emergency plans.

DEP/BRP is the specific agency responsible for evaluating information from the TMI staff. and all other sources and recommending to PEMA that protective actions be taken. The BRP has sheltering and evacuation as protective action options. The most appropriate protective action for a particular situation will depend on the magnitude of the release, duration of the release, wind speed,

. wind direction, time of day and transportation constraints. In the case of a General Emergency, circumstances may indicate the immediate need to initiate some precautionary protective action. This judgment is the responsibility of the BRP and should be based on an evaluation of the current plant conditions, dose projections relative to the PAG's and expected subsequent plant operations/evaluations.

• Off-site it is the responsibility of the State Department of Agriculture, in conjunction with the Department of Environmental .Protection, to issue guidance and coordinate actions to control contaminated agricultural products.

November 2017 TMI 4-4 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear The means to warn or advise involved persons is a responsibility of the risk county. The risk county, in coordination with the State, is also responsible for the preparation and dissemination of information material for the general public on protective actions including necessary information (evacuation routes, maps, etc.) for the implementation of protective measures in the Plume Exposure Pathway.

The population within the 10-Mile Emergency Planning Zone (Plume Exposure Pathway) will be provided, on a periodic basis, information describing the methods by which they will be notified of an emergency and specific instructions, that should be followed upon receipt of such notification.

4.3.1 Alert and Notification System (ANS) Sirens ANS is comprised of sirens distributed throughout the 5 risk counties that fall within the TMI Plume Exposure EPZ. A complete description of the siren system to include siren ratings, siren coverage, and location is located with the Emergency Preparedness Department. The TMI Station ANS meets the guidelines of Appendix 3 to NUREG-0654-FEMA-Rep. 1 Rev-1 Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants as identified in each site specific siren acoustical evaluation.

After State authorities have been notified, the ANS (sirens) and Emergency Alert System (EAS) are the primary means of notifying the population within the Plume Exposure Pathway (10-Mile EPZ). The risk counties can activate the sirens located in their portion of the county that falls within the same Plume Exposure Pathway EPZ. The signal is a three to five minute steady tone that alerts the population to tune their radios or television to the local EAS station. PEMA and risk counties will then broadcast emergency information messages advising the population of what actions should be taken, if any.

Backup means of notification is achieved through Route Alerting, which is contained within the State and respective counties' Radiological Emergency Response Plans and procedures. The means consists of utilizing vehicles with public address (PA) systems in the event the primary method of alerting and notification is unavailable. The backup method has the capability to alert and notify the public within the plume exposure pathway EPZ within a reasonable time, but does not need to meet the 15-minute design objective for the primary prompt public alert and notification system.

4.3.2 Evacuation Time Estimates The ETE study used population data from the 2010 census which includes parts of five Pennsylvania counties: Cumberland, Dauphin,

• November 2017 Lancaster, Lebanon and York. The evacuation times are based on a detailed consideration of the EPZ roadway network and population distribution. The ETE Study, contained in EP-AA-1009 Addendum 2, Evacuation Time Estimates for the Three Mile Island Plume Exposure TMI 4-5 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear Pathway Emergency Planning Zone, -presents evacuation times for daytime and nighttime scenarios under various weather conditions for the

• evacuation of various areas around the TMI Station, once a decision has been made to evacuate.

4.3.3 Potassium Iodide (Kl)

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

Based on the criteria established under the Appendix E of the Commonwealth of Pennsylvania Operations Plan, the TMI Station will recommend to government officials that the general public be notified to take Kl at a General Emergency classification in those areas were an evacuation or shelter has been recommended. Th is notification will be approved by the Emergency Director in Command and Control of PAR decision-making and off-site notifications, and performed as part of the State/ local notifications described under Sections 11.B.4 and 11.E.3 of the Exelon Nuclear Standardized Radiological Emergency Plan.

4.3.4 Public Information

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

Pamphlets outlining public education response actions are readily available for transients in the 10-Mile EPZ. In addition, emergency information is provided to the operators of other recreational areas in the 10-Mile EPZ, as defined by the Commonwealth of Pennsylvania and risk counties.

These public information publications (including telephone book emergency information, etc.) instruct the public to go indoors and turn on their radios when they hear the ANS sirens operating.

These publications identify the local radio stations to which the public should tune in for information related to the emergency.

Additional materials (e.g., such as rumor control numbers, evacuation routes, information on inadvertent siren soundings, etc.)

• November 2017 may also be included in these publications based on agreements with responsible State and risk county agencies.

b. News Media Education

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

4.3.5 Protective Action Recomm*endations (PARs) for the General Public To aid the Emergency Response Organization during a developing emergency situation, EP-AA-111, "Emergency Classification and Protective Action Recommendations" has been developed based on Section J.10.m of the Emergency Plan.

4.4 Protective Actions for Onsite Personnel During an emergency, personnel may* be required to temporarily relocate to prevent or minimize exposure to radiation and radioactive materials. The following subsections discuss the policies applying to sheltering, evacuation and personnel accountability during emergencies at the TMI site.

At the time an emergency is declared, an announcement is made on the site public address system to all personnel within the Owner Controlled area. The announcement will include the classifications of the event, a brief description of the event, and actions taken by site personnel. Shift personnel will proceed to their emergency assignments .

The TMl-1 licensee retains complete authority to determine and maintain sufficient control of all activities including the authority to exclude or remove personnel and property for land areas within the exclusion area and contamination will, thereby, be controlled. In addition, there are no areas for producing agricultural products within the exclusion area. In-plant contamination control will be in accordance with approved Radiological Controls procedures.

The primary protective measures for onsite personnel during an emergency is prompt evacuation from areas, which are affected by significant radiation, contamination, airborne radioactivity or other personnel hazards. All persons onsite at the time an emergency is declared shall be notified by means of the plant page supplemented by designated personnel providing notification in areas that the page does not cover .

• November 2017 TMI 4-7 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear 4.4.1 Emergency Personnel Exposure

• Exposure to personnel remaining onsite as or in support of ERO activities will be monitored. This may be accomplished through continuous monitoring for habitability at designated emergency and support facilities.

Dosimetry will be issued to personnel leaving or working outside a monitored facility, and will be available to ERO personnel located inside a site emergency facility, in the event of a radiological release or elevated plant radiation levels, as applicable, per approved procedures. Additional provisions have been made for dosimetry issue at the site entrance gates or other locations, if required. Dosimetry will be periodically read and recorded in accordance with approved RP procedures.

Emergency personnel, including those involved in the removal of injured persons, undertaking corrective actions, performing assessment or personnel decontamination, and providing first aid and support to ambulance services will have their radiation dose controlled in accordance with approved procedures and normal RP practices.

When offsite emergency personnel are called to respond to TMI, station RP support is provided to support these activities, which include the monitoring and control of radiation exposure and evaluation of radiological hazards.

4.4.2 Radiological Monitoring and Decontamination Personnel and equipment decontamination will be initially accomplished at the Radiation Protection Access Control Point where specialized equipment and supplies are available. Procedures are written with specific details for decontamination. For personnel within the Protected Area, emergency situations, which require decontamination will be handled in accordance with these procedures.

All personnel leaving a Radiological Controlled Area (RCA) will be monitored for contamination. Any individual found to have contamination levels in excess of thresholds established in Radiation Protection (RP) procedures will be considered contaminated.

Personnel found to be contaminated will undergo decontamination by radiological controls personnel (or other designated personnel as specified in Radiation Protection Procedures). Measures will be taken to prevent the spread of contamination: Such measures may include isolating affected areas, placing contaminated personnel in "clean" protective clothing before moving, and decontaminating affected personnel, their clothing and equipment prior to release, in accordance with applicable station Radiation Protection Procedures .

• November 2017 TMI 4-8 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear In the event that a release of contaminants has occurred or is occurring, in-plant potable water systems will be secured

• to prevent possible contamination. If food and water supplies are brought in for emergency personnel who remain on-site these supplies will be packaged in sealed containers and will be monitored by Radiation Protection personnel (using standard Rad Con practices and procedures) prior to use or consumption and on a normal routine basis. Any food or water supplies discovered as contaminated will immediately be disposed of as waste and will not be used.

Upon receipt of information that the emergency has entered recovery phase, in-plant facilities and areas will be surveyed, sampled, and cleared for use, or controlled as necessary, in accordance with *applicable Radiation Protection practices.

4.4.3 Personnel Accountability/ Site Evacuation Upon declaration of a Site Area Emergency, General Emergency and/or at the discretion of the Station Emergency Director, essential personnel within the Protected Area will be accounted for at the Control Room, TSC and OSC unless other factors (e.g., security events) advise against it.

Non-essential personnel will be directed to proceed to their vehicles directly and to evacuate to designated Remote Assembly Areas or dismissed to their homes. The Station Emergency Director based on the prevailing radiological conditions will determine evacuation routes. This evacuation will be accomplished using private vehicles.

In support of these operations, a sweep of buildings, trailers, and other areas of the Owner Controlled area will commence to ensure that all persons have assembled and/or evacuated the site.

Refer to Section J of the Standard Plan for specific requirements for the initiation and completion of personnel accountability and the evacuation of non-essential personnel from the site. Search and rescue operations will

• be implemented to locate any missing persons.

4.4.4 Monitoring of Evacuees At the Remote Assembly Areas (Figures TMI 4-1 and TMI 4-2), personnel and vehicles from the TMI site will be monitored for radioactive contamination, if necessary. Individuals found to be contaminated will be decontaminated in accordance with applicable Radiation Protection Procedures. Vehicles found to be contaminated will be impounded until they can be decontaminated. Inclement weather will not affect the direction of the traffic flow, but may increase evacuation times .

• November 2017 TMI 4-9 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear If anyone is found to be contaminated, showers, sinks and decontaminating supplies are available in close proximity to the plant.

Equipment for decontamination personnel will be stored in Emergency Supply Lockers. Portable survey instruments are available and routinely calibrated for use in decontamination operations. All skin contamination problems will be treated using accepted Radiation Protection practices.

For contaminated personnel inside the Protected Area, the preferred decontamination facility will be those onsite at the TMI Site Laboratory, if accessible; otherwise offsite facilities will be used.

The registering and monitoring of the general public evacuating from the Plume Exposure Pathway EPZ, as described in Section 11.J.12 of the Exelon Nuclear Standardized Radiological Emergency Plan, will occur at designated facilities per the respective State and County Radiological Emergency Response Plans.

4.5 Severe Accident Management Accident management consists of those actions taken during the course of an accident, by the Emergency response Organization (ERO), specifically: plant

• operations, technical support, and plant management staff in order to:

• Prevent the accident from progressing to core damage;

• Terminate core damage once it begins;

• Maintain the capability of the containment as long as possible; and

• Minimize on-site and off-site releases and their effects.

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

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

AR 1362747.44) 5.2 Assessment Resources 5.2.1 Radiation Monitoring System The onsite Radiation Monitoring System contributes to personnel protection, equipment monitoring, data gathering, and accident assessment by measuring and recording radiation levels and concentrations of radioactive material at selected locations within the plant. The Radiation Monitoring System alarms and initiates required emergency actions when radiation levels or radionuclide concentrations exceed predetermined levels. Area, liquid, and atmospheric monitoring subsystems are required to perform these functions. Specific details regarding radiation monitoring and effluent monitoring systems can be found in system design descriptions (SDDs ), site Final Safety Analysis Reports, and the TMI Radiation Monitoring Setpoint Procedures.

• November 2017 The data from these subsystems are displayed by readout in the Control Room. Selected channels are recorded by recorders and/or the plant process computer, which are also located in the Control Room.

TMI 5-3 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear In general the radiation monitoring equipment is designed in accordance with the following:

• Each monitoring station has adjustable alarm, alert, and power supply failure alarms.

• Solid-state circuitry is used except for primary detectors.

• Most AC operated radiation monitoring equipment, except for the pump assemblies, is provided with power from the battery-backed, inverter-fed vital power supply bus.

• Each radiation monitor is capable of being checked periodically with solenoid actuated check sources.

• A pulse generator or solid sources are used for electrically checking each monitor or subsystem.

• The modules are designed so that an alarm and/or indication is initiated when failure occurs anywhere in the channel.

1. Area Radiation Monitoring The TMl-1 area radiation monitoring subsystem is comprised of channels, which utilize an ion chamber detector hous~d in a weatherproof container.

2. Containment Radiation Monitors Post accident radiation levels in containment are monitored by two channels of fully qualified high range area monitors. These monitors are ion chamber detectors and are designed to withstand a LOCA.

Readout modules are located for these detectors on the radiation monitoring panel in the cont~ol room.

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

3. Atmospheric Radiation Monitoring Each installed atmospheric monitor (except the condenser off-gas, ESF ventilation exhaust and waste gas monitor) is comprised of a particulate measuring channel, iodine measuring channel, and a gaseous measuring channel. The atmospheric radiation monitor subsystem is comprised of monitors with fixed and movable particulate filters, and fixed radioiodine filters. Representative samples are obtained by means of a sampling head placed in a ventilation duct.

Movable airborne monitors are typically used in the spent fuel handling area during refueling operations and in the radiochemical laboratory during laboratory sample preparation operations. These monitors are supplemented with various other portable radiation monitors. Each monitor contains three channels for particulate, iodine, and gaseous monitoring, respectively.

November 2017 TMI 5-4 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear

4. Liquid Radiation Monitoring

• The liquid radiation monitoring subsystem is comprised of monitors, each of which has a sampler, detector, and Control Room ratemeter module (exceptions are the IWTS/IWFS

• discharge monitor, waste treatment system discharge monitor and the turbine building sump pump). The monitors provide visual indications in the Control Room.

The TMl-1 Primary Coolant Letdown monitor also contains a high range channel.

5. Post Accident Sampling System (PASS)

Liquid Reactor Coolant System Post Accident Sample System {PASS) samples may be taken from the pressurizer and decay heat and reactor coolant letdown systems. Liquid samples may be analyzed for isotopic concentration, boron concentration, chloride concentration and dissolved gases.

The Containment Atmosphere Post Accident Sampling System (CATPASS) is used to sampling isotopic concentration in the containment atmosphere. MAP-5 microprocessor stations sample iodine and particulates in condenser off-gas and auxiliary and reactor building exhausts.

5.2.2 Fire Protection Devices TMI has implemented and maintains a Fire Protection Program as described in the updated FSAR for TMl-1. The Fire Protection Program is controlled under TMl-1 license conditions.

5.2.3 Seismic Monitoring Strong motion recording systems at TMI measures ground motion and structural vibrating response caused by an earthquake occurring in the vicinity of the site. Cassette magnetic tape recorders located in the TMl-1 Control Room receive information supplied by triaxial sensor units which are firmly mounted on the Reactor Building. One triaxial sensor unit is attached immediately outside of the containment wall at the base of the Reactor Building. A second triaxial sensor is situated along the same Reactor Building axis, but is attached to the Reactor Building ring girder.

The triaxial sensor units begin to supply seismic data to the magnetic tape recorder after a signal is sent to the sensors by a remote starter unit. A remote starter unit attached to the base of the Reactor Building provides a signal for its systems sensor units when the starter unit detects a ground acceleration greater than a present threshold level. The remote starter also actuates an annunciator in the TMl-1 control room labeled "Threshold Seismic Condition". If the ground acceleration exceeds the horizontal or

• November 2017 vertical setpoints, a seismic trigger, also mounted on the base of the Reactor Building, will cause a TMl-1 annunciator labeled "Operating Basis Earthquake" to actuate.

TMI 5-5 EP-AA-1009 (Revision 27)

Three Mile Island Station Annex Exelon Nuclear The time history of a ground motion and resulting vibrating response can be displayed by using magnetic tape cassettes containing the recorded data, and the magnetic tape playback system in the control rooms. The magnetic tape playback system produces visual playouts of selected magnetically recorded data. This is accomplished with a strip chart recorder built into the playback system. A visual playout allows quick analysis of the earthquake. The magnetic tapes are available also for detailed analysis.

Peak reading accelerographs are anchored to Class 1 selected items.

These accelerographs will produce a permanent record of the peak amplitude of the low frequency accelerations caused by seismic disturbances.

This record is in the form of magnetic erasure clips which must be developed using the magnetic developer kit. After developing, these clips can be examined to verify seismic response which had been determined analytically.

5.2.4 Onsite Meteorological.Monitors At TMI, basic meteorological information is obtained from a weather tower maintained at the north end of the Island. Real time information can .be obtained from the plant process computer .

• The meteorological measurement system is deployed on a 150 ft. tower.

It measures wind speed and wind direction at 98 ft. and 145 ft. above grade. There are redundant speed and direction sensors at the 98 ft.

level. Temperature is measured at both 31 ft. and 145 ft. from two sets of platinum sensors. Temperature difference (~T) is also derived and recorded. A recorder located inside the meteorological building adjacent to the weather tower records all of the above information. The Control Room also has a recorder with wind speed, direction, temperature, and differential temperature which is an indication of atmospheric stability.

Meteorological data can be remotely interrogated by telephone by NRC and Commonwealth of Pennsylvania.

Protective Measures personnel are capable of making real-time offsite estimates of atmospheric effluent transport and diffusion following an accidental airborne radioactive release from the plant. Real time meteorological information is obtained from the plant process computer.

The recorder at the meteorological building located at the north end of TMI has a storage capacity of several months of data. Beyond that time period the meteorological data is permanently stored in a history file.

Back-up meteorological information is available from the National Weather Service directly and indirectly from other sources that collect National Weather Service information ..

Three Mile Island Station Annex Exelon Nuclear 5.2.5 Process Monitors

• Process monitors measure appropriate parameters that are indicative of the status of various plant systems and the reactors. These parameters are displayed and recorded in the Control Room, or at local panels in the plant 5.2.6 Laboratory Facilities The TMI laboratory facility is equipped to provide the water chemistry and radiochemical analysis support required during normal plant operations and emergencies.

5.3 Protective Facilities and Equipment Personnel protective action is a function of the nature of the hazard (e.g.,

preparing for a hurricane is somewhat different from preparing for radiological hazards). Preplanned responses to basic hazards, high wind, flooding, earthquakes, and radiation exposure, are an integral part of the Emergency Plan.

A fundamental concept in personnel protection is the evacuation of all individuals not essential to the operation, safety, security, and damage control of the plant. Obviously some hazards can occur before significant protective action can be applied (e.g., earthquake). When the situation permits positive action, the appropriate alarms are sounded and all personnel on the site either assume assigned emergency responsibilities or prepare for evacuation .

Provision has been made for adequate supplies and protective equipment for all personnel who may be required to perform emergency activities. Specific quantities of each type are detailed in station procedures and include equipment for personnel monitoring, determining the magnitude and continuously assessing the impact of the release of radioactive material, decontaminating personnel and providing emergency first aid. Additionally, a current prescription and adequate supplies of potassium iodide are maintained for issue to personnel exposed or suspected of exposure to radioactive iodine.

Onsite locations have been designated as emergency assembly points or areas where emergency teams will be assembled in accordance with the Emergency Plan Implementing Procedures or as directed by the Station Emergency Director.

. Major locations for onsite protective equipment and supplies are the Control Room, access control point, and processing center. Additional information regarding protective facilities can be obtained by consulting the UFSAR.
