Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 1.0 PURPOSE The purpose of Part 5A is to provide sufficient information to ensure the compatibility of the proposed emergency plans (for onsite areas) with facility design features, site layout, and site location. In an effort to maintain consistency throughout the fleet, the content of Part 5A is based on the Tennessee Valley Authoritys (TVA) Nuclear Power Radiological Emergency Plan (NP-REP), Generic Part, which has been approved by the U.S. Nuclear Regulatory Commission (NRC) for use at all of the TVA operating nuclear facilities. Site-specific information is included in Appendix A to this Plan to address emergency planning for the Clinch River Nuclear (CRN) Site. This Plan addresses pertinent requirements and associated guidance contained in NUREG-0654, Revision 1, Supplement 2, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants - Criteria for Planning in an Early Site Permit Application (NUREG-0654 Supplement 2) to provide major features of the Emergency Plan. Information that was not available to TVA during the development of the CRN Site Early Site Permit Application (ESPA) will be addressed in the Combined License Application (COLA). Information to be addressed at COLA includes analysis normally found in a Design Certification Application and not currently available such as specific accident development details, staffing levels, required safety-related equipment.
In accordance with 10 CFR Part 52, Early Site Permits; Standard Design Certifications; and Combined Licenses for Nuclear Power Plants, Part 5A addresses the emergency planning requirements of Appendix E to 10 CFR Part 50, Section III, the Final Safety Analysis Report; Site Safety Analysis Report. Part 50 Appendix E states, The final safety analysis report or the site safety analysis report for an early site permit that includes major features of emergency plans under 10 CFR 52.17(b)(2)(i) of this chapter shall contain the plans for coping with emergencies. In addition, these regulations require that the application must contain the means which the standards of § 50.47(b) will be met.
In the development of this Plan, TVA has considered the applicable guidance provided in the following documents with consideration given to the proposed exemptions contained in Part 6 of the ESPA:
NUREG-0654, Revision 1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants (NUREG-0654).
NUREG-0654, Revision 1, Supplement 2.
Regulatory Guide 1.101, Revision 3, Emergency Planning and Preparedness for Nuclear Power Reactors (RG 1.101).
Section 13.3 of Regulatory Guide 1.70, Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants (LWR Edition) (RG 1.70).
1 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Section 13.3 of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition (NUREG-0800).
As specified in NUREG-0654 and RG 1.101, this Plan provides for the following:
Adequate measures are taken to protect employees and the public that may be located within the Site Boundary.
Individuals having responsibilities during an emergency are properly trained.
Procedures exist to provide the capability to cope with a spectrum of emergencies ranging from those of little consequence to major core melt.
Equipment is available to detect, assess, and mitigate the consequences of such occurrences.
Emergency action levels and procedures are established to assist in making decisions.
This Plan has been developed to respond to potential radiological emergencies at the CRN Site as they may apply to small modular reactors (SMRs). As discussed in Site Safety Analysis Report (SSAR) Section 13.3 of this EPSA, the SMR technologies under consideration do not have postulated design basis accidents that would result in dose consequences that are large enough to require offsite emergency planning, the overall scope of this plan delineates the actions necessary to safeguard onsite personnel (within the site boundary) and minimize damage to property. As discussed in Part 3 of this ESPA, for postulated beyond design basis accidents, analysis has concluded that, because of the slow progression rate, sufficient time is available to initiate appropriate mitigating actions to protect the health and safety of the public beyond the Site Boundary.
The NRC requires a level of emergency preparedness commensurate with the potential consequences to public health, safety, common defense, and security at the CRN Site. This Plan considers the proposed exemptions contained in Part 6 of the ESPA. Implementation of this Plan is not dependent on the comprehensive emergency management plan (CEMP) nor would TVA impose a requirement on offsite agencies to implement this Plan.
As addressed in the Federal Emergency Management Agencys (FEMA) Comprehensive Preparedness Guide 101, Developing and Maintaining Emergency Operations Plans (CPG-101), if determined appropriate, government officials may utilize a CEMP approach to emergency planning to implement ad hoc protective actions to protect the public.
The CRN Site ESPA (Part 5A, Emergency Plan) consists of this Generic Part and a site specific Appendix A.
2 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 2.0 SCOPE This Plan provides information regarding emergency preparedness and response planning for the CRN Site and addresses organizational responsibilities, capabilities, actions, and guidelines for TVA during a radiological emergency. It also describes the centralized emergency management concept which was approved by the NRC Commissioners via COMJA-80-37 (January 21, 1981). Additional guidance regarding the centralized emergency management concept can also be found in NRC SECY-96-170 (August 5, 1996) and NRC SECY-10-0078 (June 16, 2010).
2.1 APPENDICES Additional Radiological Emergency Plan information specific to the CRN Site is included as the CRN Site ESPA (Part 5A, Emergency Plan / Appendix A); referred to in the remainder of this document as Appendix A.
Appendix A details facility features, capabilities, equipment, and responsibilities. The Generic Part together with Appendix A, describes the methods TVA will use to:
- 1. Detect an emergency condition.
- 2. Evaluate the severity of the problems.
- 3. Notify federal, State, and local agencies of the condition.
- 4. Activate emergency organizations.
- 5. Evaluate the possible offsite consequences.
- 6. Mitigate the consequences of the emergency.
Since TVAs authority is limited to TVA-owned and controlled property, the State of Tennessee (State) and local agencies are responsible for ordering and implementing actions offsite to protect the health and safety of the public. If determined appropriate, government officials may utilize a CEMP approach to emergency planning to implement ad hoc protective actions to protect the public.
2.2 IMPLEMENTING PROCEDURES TVA develops specific procedures to ensure that the Plan is implemented as designed. These implementing procedures are designed to ensure that emergencies are properly evaluated, rapid notifications made, and assessment and onsite protective actions performed. These procedures are compiled in the Emergency Plan Implementing Procedures (EPIPs). Site specific procedures for abnormal and emergency operation and control exist but are not included in the EPIPs. These plant operating procedures are designed to ensure the implementation of the EPIPs.
3 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 2.3 STATE RADIOLOGICAL EMERGENCY PLAN The State Radiological Emergency Plan is referenced in Appendix A, Attachment 1. This Plan provides for the coordinated response of the State and affected local governments and defines roles and responsibilities.
As addressed in the Federal Emergency Management Agencys (FEMA) Comprehensive Preparedness Guide 101, Developing and Maintaining Emergency Operations Plans (CPG-101), if determined appropriate, government officials may utilize a CEMP approach to emergency planning to implement ad hoc protective actions to protect the public.
The responsibilities of these major organizations are summarized in Table 2-1.

Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 2.4 NATIONAL RESPONSE FRAMEWORK The National Response Framework (NRF) Nuclear/ Radiological Incident Annex provides for timely, coordinated response by federal agencies to a fixed nuclear power plant facility incident.
The NRF is activated by either the affected State notifying the Department of Homeland Security (DHS), or the utility notifying the NRC of a radiological emergency at a nuclear plant site. The NRF is not included as part of the TVA Radiological Emergency Plan. Should additional radiological monitoring support be required the appropriate State agency will make the request through DHS. The persons authorized to request this assistance, the specific resources expected, and resources available to support the federal response are provided in the respective State plans.
The NRF may be used by federal agencies in radiological emergencies. The NRF primarily concerns offsite federal response in support of State and local governments with jurisdiction for the emergency. The NRF provides the federal government's concept of operations for responding to radiological emergencies, outlines federal policies and planning assumptions, and specifies authorities and responsibilities of each federal agency that may have a significant role in such emergencies. The Central Emergency Control Center (CECC) Director is the TVA representative authorized to request federal assistance. Such a request from TVA will be made to the NRC.
TVA will utilize the CECC in Chattanooga, Tennessee as the Emergency Operations Facility (EOF) for the Clinch River Nuclear Site. The CECC serves as the EOF for the other TVA nuclear plants (Browns Ferry Nuclear Plant (BFN), Sequoyah Nuclear Plant (SQN), and Watts Bar Nuclear Plant (WBN)).This multi-site EOF was previously approved for use by the NRC in COMJA-80-37. Attachment 1 of this Plan provides additional description of and justification for the location of the CECC.
Because of the close proximity of the U.S. Department of Energy (DOE) Oak Ridge Reservation to the CRN Site, DOE response, should assistance be requested, is expected within 1 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
Additional information about the NRF and available support is provided in NRC RIS 2005-13, NRC Incident Response and the National Response Plan (RIS 2005-13), NUREG-0728, Emergency Preparedness and Incident Response Programs (NUREG-0728) or the FEMA website (www.fema.gov) as well as in the Agency Emergency Response Plan (TVA-SPP-35.01).
5 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 3.0 PROCESS 3.1 ROLES AND RESPONSIBILITIES The development, implementation, and maintenance of the NP-REP is the responsibility of the TVA Nuclear organization. The General Manager, Support Services has delegated the authority for overall program control of the NP-REP to the Director, Emergency Preparedness as described below. Appendix A provides detailed staffing and organizational roles and responsibilities for the CRN Site minimum required Onsite Emergency Management Organization positions.
3.1.1 Emergency Management Organization (Concept of Operations)
The CRN Site Emergency Management Organization is divided into two categories; the Onsite Organization and the Offsite Emergency Organization. A block diagram of the Onsite Organization is presented in Appendix A and the Offsite Emergency Organization is presented in Figure 3-1. All designated Emergency Management Organization personnel are required to participate in the Fitness for Duty Program.
The Onsite Organization is comprised of the Site Emergency Director (SED) and technical staff located in the Technical Support Center (TSC), a Control Room staff of Operations personnel, and additional support personnel located in the Operations Support Center (OSC). The Onsite Organization is responsible for the onsite response to an emergency condition. Onsite activities are directed by the SED to include such functions as Control Room operations, technical assessment, emergency mitigation analysis, onsite radiation surveys, and dose tracking for site personnel.
The Offsite Organization is designated as the CECC staff. The CECC staff is comprised of a CECC Director, a supporting group of technical assistants, and representatives of other TVA organizations. The CECC Director and supporting technical assistants report to the CECC during an emergency as required. Other TVA organizations will send representatives to the CECC as requested by the CECC Director.
The CECC is responsible for directing and coordinating the overall TVA response to an emergency condition. Functions such as offsite radiological monitoring and dose assessment, public information, State and local government coordination, and additional plant assessment are handled by the CECC relieving the Onsite Organization of the many peripheral duties necessary for the successful emergency response.
3.2 ONSITE ORGANIZATION Under normal conditions the Site Vice President is in charge of activities at the site and the Plant Manager is responsible for the safe efficient operation of the plant. The person primarily responsible for mitigation of an emergency is the SED. Upon declaration of an emergency the Shift Manager (SM) on duty initially fills the position of SED and directs emergency response from the Control Room. This position is transferred to the TSC when that facility is activated.
Once the TSC is activated, the SED and the TSC can provide technical support to the Control Room as part of their overall response to the emergency.
6 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
The CRN Site is staffed on a continual 24-hour basis. The minimum staffing requirements for plant operations are established in the plant Technical Specifications. The staff responsibilities are as outlined in the SSAR, and are unchanged during an emergency. The on-shift composition listed in Appendix A may be less than the minimum requirements for a period of time in order to accommodate unexpected absences of personnel provided action is taken to restore the composition within established time requirements.
Under emergency conditions, the normal plant staff is supplemented as shown in Appendix A.
Appendix A also provides descriptions of the responsibilities of the personnel who augment the normal plant operating organization. Support personnel will be notified to report as required by the situation. Staffing time for the augmenting forces is indicated in Appendix A. This time could vary slightly, depending upon the time of day, weather conditions, immediate availability of personnel, and radiological conditions.
The Onsite Organization augments the shift operations crew. If members of the Onsite Organization are not present when an emergency occurs, the SM on-duty, or a designated Unit Supervisor when acting as the SM, is designated the SED and acts as such until relieved by the SED assigned to the TSC.
Upon detection of a known or suspected emergency, the SM on-duty refers to a CRN-EPIP to determine the classification of the emergency. After determining the classification of the incident, the SM assumes the responsibilities of SED and initiates the appropriate procedure referenced by the CRN-EPIP. Emergency communications / notifications with State, local and federal agencies, along with staffing instructions for the emergency response facilities are specified in CRN-EPIPs.
CRN-EPIPs designate personnel who staff the Emergency Notification System (ENS) and Health Physics Network (HPN) (NRC FTS 2000 System) Communication Systems. CRN-EPIPs also designate the interface with the NRC during TSC operation.
3.3 OFFSITE ORGANIZATION Figure 3-1 provides a diagram of the Offsite Organization, including those positions that must respond within a prescribed time of an Alert or higher (see Section 4.0, Emergency Conditions) emergency declaration at the CRN Site. The prescribed response times for the Offsite Organization will be addressed in the COLA.
Activation for the CECC is accomplished within a prescribed time following declaration of an Alert or higher (see Section 4.0, Emergency Conditions) emergency classification at the CRN Site, depending upon time of day, weather conditions, or immediate availability of personnel.
The prescribed activation time for the CECC for an event at the CRN Site will be addressed in the COLA.

Figure 3-1 Offsite Emergency Organization 15 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 4.0 EMERGENCY CONDITIONS 4.1 CLASSIFICATION SYSTEM TVA utilizes the following emergency classifications:
Notification of Unusual Event (NOUE)
Alert Site Area Emergency General Emergency This system of classification is consistent with the systems used by State and local emergency organizations. The emergency classifications are graded according to severity and immediate actions are taken to cope with the situation. Escalation to a higher class, or termination, occurs during the course of an emergency if warranted by conditions. Examples of plant conditions and their recommended emergency classes are given in the CRN-EPIPs. These procedures also specify the initial prompt notifications, and information to be provided to State and local emergency organizations. Examples of Initiating Conditions (ICs) and specific instrument readings, if appropriate for the various classifications, are provided in the EPIPs.
NEI 99-01, Rev. 6, Development of Emergency Action Levels for Non-Passive Reactors, provides definitions of the emergency classifications. Not all elements of the definitions apply to SMR technology. These differences are addressed in the following sections.
4.1.1 NOUE This classification provides early and prompt notification of events that are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated. No releases of radioactive material requiring response or monitoring are expected unless further degradation of safety systems occurs.
The purposes of the NOUE are: (1) to ensure that the first steps in activating emergency organizations have been carried out; and (2) to provide current information on the unusual event.
TVA maintains the NOUE classification until closeout or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
16 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 4.1.2 Alert An Alert classification is indicated when events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of Hostile Action. Any releases are expected to be limited to small fractions of the Environmental Protection Agency (EPA) Protective Action Guides (PAG) exposure levels.
The purposes of the Alert classification are: (1) to ensure that emergency personnel are readily available to respond if the situation becomes more serious or to perform confirmatory radiation monitoring, if required; and (2) to provide offsite authorities current status information.
TVA maintains the Alert class until event termination or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.1.3 Site Area Emergency A Site Area Emergency is indicated when events are in process or have occurred which involve an actual or likely major failures of plant functions needed for protection of the public or Hostile Action that results in intentional damage or malicious acts: (1) toward site personnel or equipment that could lead to the likely failure of or; (2) that prevent effective access to equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA PAG exposure levels beyond the site boundary.
The purposes of the Site Area Emergency classification are: (1) to ensure that emergency response centers are staffed; (2) to assure that monitoring teams are dispatched; (3) to assure that personnel required for evacuation of near-site areas are at duty stations if the situation becomes more serious; and (4) to provide current information for, and consultation with, offsite authorities and the public.
TVA maintains the Site Area Emergency classification until event termination or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.1.4 General Emergency A General Emergency is indicated when events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity or Hostile Action that results in an actual loss of physical control of the facility. Due to the SMR design, releases are not expected to exceed EPA PAG exposure levels offsite.
The purposes of the General Emergency classification are: (1) to initiate predetermined protective actions for the public; (2) to provide continuous assessment of information from the site and offsite; and (3) to initiate additional measures as indicated by releases or potential releases of radioactivity.
17 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
TVA maintains the General Emergency until event termination. TVA notifies the State authorities and the NRC. The State notifies local authorities unless the initial classification is General Emergency, in which case TVA initially notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.2 IDENTIFICATION OF EMERGENCY CLASSES TVA uses a variety of methods to identify emergency situations and to categorize them. As indicated in the CRN-EPIPs, emergencies can be caused by natural disasters such as tornadoes or floods, hazards such as aircraft crashes, releases of toxic gases, or breaches of plant security, as well as by conditions involving plant systems directly.
Recognition of the emergency class is primarily a judgment matter for plant personnel. The ICs used for recognizing and declaring the emergency class are based on specific measurable values or observable conditions defined as Emergency Action Levels (EALs). These can be combinations of specific instrument readings (including their rates of change), annunciator warnings, time periods certain conditions exist, etc. The instrument readings and parameters required for determination of these EALs are detailed in the CRN-EPIPs. TVA uses these EALs as thresholds for determining the emergency classifications. The EALs are reviewed annually by the State.
TVA maintains the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indication to plant operators that an emergency action level has been exceeded and to promptly declare the emergency condition upon identification of the appropriate EAL.
18 Revision 1

Figure 8-1 Central Emergency E y Control C Center 30 Revission 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 9.0 ACCIDENT ASSESSMENT 9.1 ONSITE In-plant accident assessment actions are carried out by the plant emergency staff in order to properly characterize and classify the emergency, determine the actual or potential radioactivity releases, and determine the effect on plant personnel.
Assessment methodology consists of actions carried out through plant operating procedures as well as CRN-EPIPs. At the onset of an emergency, plant operating procedures (normal, abnormal, and emergency) assist the plant operator and SED in identifying the cause of the emergency, actions necessary to control the emergency, radioactivity release rate, if any, and in-plant radiation levels. The CRN-EPIPs assist the SED in: (1) identifying and reassessing emergency classification; (2) determining the need for plant area evacuation; (3) initiating activation of onsite emergency organizations; (4) directing the utilization of needed medical and/or decontamination facilities; and (5) implementing predetermined security and access control plans.
Each of the above-mentioned activities is described within the plant operating procedures or CRN-EPIPs, as applicable, for a given situation. The distinct breakdown of assessment actions into operating procedures and implementing procedures is necessary since some assessment actions are necessarily carried out prior to identification or classification of an emergency. The procedures to ensure that emergencies are properly evaluated, timely notifications are made, and assessment and onsite protective actions are performed, are compiled in the CRN-EPIPs.
These procedures are summarized by topic in Appendix A, Attachment 1.
Under severe emergency conditions, and as required by the plant emergency operating procedures, the onsite Emergency Management Organization is responsible for recognition of severe emergency conditions, transition to, and implementation of the Severe Accident Management Guidelines (SAMGs).
9.2 OFFSITE 9.2.1 General Information TVA maintains the capability to assess the consequences of potential or actual releases of radioactivity offsite. If determined appropriate by State and local agencies, protective actions for the protection of the public may be implemented using an all hazards approach to emergency planning.
Implementing procedures have been developed for the CECC to ensure that emergencies are properly evaluated, timely notifications are made, and assessment and onsite protective actions are performed. Once an SMR technology is selected, the details on staffing levels, response times, and accident progression rates will be known and can then be reflected in a set of EPIPs similar to the following list:

Each vehicle has an air sampler, radiation measurement equipment, a generator, radio, and other assorted equipment.
A detailed listing of the minimum required equipment is available in the CECC-EPIPs.
These vehicles are dispatched for environmental monitoring for Site Area Emergency and General Emergency classifications. TVA may deploy these vehicles for the NOUE and Alert classifications, if warranted. One or more vehicles is stationed at the CRN Site.
Each sampling team has the capability to:
Obtain environmental samples for analysis.
Make direct radiation readings.
Collect air samples and analyze them for gross beta-gamma radioactivity over a range of energies.
Collect air samples and analyze them for radioiodine in the field, to concentrations as low as 10-7 microcuries/cc.
CRN-EPIPs describe the composition and activation of sampling teams.
For the Site Area Emergency and General Emergency classifications, teams are dispatched from the nearest location. Teams may be deployed for the NOUE or Alert, if warranted. If necessary, TVA can coordinate team transport via helicopter or fixed-wing aircraft.
The TSC Rad Protection Manager or CECC Environs Assessor can request assistance from a neighboring plant for environmental monitoring, if deemed necessary.
TVA has aquatic monitoring teams located at Chattanooga, Tennessee, and Knoxville, Tennessee. These teams have boats that can be deployed to obtain samples from the river for subsequent analysis for radioactivity in the laboratories.
33 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 9.2.3 Analyzing Environmental Samples The sampling teams may send samples to the WARL for analysis.

9.2.4 Meteorological Information 9.2.4.1 Primary Meteorological Measurements TVA has developed the meteorological measurements program to conform to the intent and guidance of Regulatory Guide 1.23, Meteorological Monitoring Programs for Nuclear Power Plants (RG 1.23). Wind direction, wind speed, and air temperature are measured at two levels.
The temperature difference is used to estimate the Pasquill stability class. Precipitation and dew point temperature are also measured. Hourly and 15-minute average meteorological data from the plant Environmental Data Station are available to the CECC, TSC, State, and LRC. More specific information on the meteorological measurements program can be found in Section 2.3 of the CRN SSAR.
9.2.4.2 Backup Meteorological Data Estimation Procedures TVA has prepared objective backup procedures to provide estimates for missing or garbled data needed to perform dose calculations and to determine transport estimates. They incorporate available onsite data. Each procedure has an accompanying statement of reliability.
9.2.4.3 Real Time and Forecast Meteorological Data The CECC Meteorologist has the responsibility for providing meteorological information to CECC Staff. The dose assessors use this meteorological information to project doses. The meteorological support actions and projection of doses are discussed in detail in CECC-EPIPs.
Meteorological support may be provided in the CECC or from a remote location.

9.2.5 Dose Assessment On-shift dose assessment capability is maintained at the CRN Site, and can be implemented (if needed during the initial phase of an emergency) until the CECC is activated and assumes the dose assessment function.
34 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Doses from emergency-related releases of radioactivity are estimated using a combination of calculations, field measurements, and laboratory analyses of environmental samples. Using plant operational data, field measurements, and effluent monitor readings, actual or potential releases of radioactivity are analyzed by the plant staff, the Radiological Assessment staff, or the CECC Plant Assessment Team to generate or modify a source term for use in the dose assessment.
With this information, the CECC dose assessment team can predict doses through the use of several models and/or methods described in the CECC-EPIPs. These models provide a means of estimating personnel exposures throughout the emergency and recovery period. Environs measurements are used, to the extent possible, to confirm doses projected by modeling.
A preliminary dose projection is performed following receipt of measured effluent release data (the source term) and meteorological data. The preliminary dose projection is followed up by a more detailed assessment using computerized dose models. Manual dose assessment methods are available for use in the event that the computer is unavailable. Input to the detailed calculations includes measured source terms, projected future releases, near real-time and forecast meteorological data, field measurements of exposure rates and/or airborne radioactivity in the environs around the plant, or a combination thereof. Field measurements are used to estimate doses, and (especially in the case of an unmonitored release) source terms, and to verify doses projected using models.
After termination of emergency-related releases to the atmosphere, integrated doses are calculated to assist in recovery/reentry operations.
35 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 10.0 PROTECTIVE RESPONSE 10.1 ONSITE PROTECTIVE ACTIONS FOR RADIOLOGICAL EVENTS In the event of an unplanned significant release of radioactivity or sudden increase in radiation levels, it is the responsibility of the SED to make the decision concerning the necessity for building and area evacuation. In arriving at this decision, the primary consideration is personnel safety. The SED may use the various radiation and airborne radioactivity monitors placed throughout the plant, with readout in the Control Room, to assess the extent of the radiological hazards and to determine the extent of evacuation necessary.
The assembly/accountability alarm is used to initiate the assembly of site personnel. The public address system is used if only specific areas are to be evacuated. Nuclear Security Services personnel patrol the area between the security boundary described in the Physical Security Plan and the Site Boundary, and evacuate any nonessential personnel.
Upon hearing the emergency alarm, persons in the plant areas proceed to their pre-assigned areas to be accounted for and await further instructions from the SED. The pre-assigned areas are designated in approved procedures. Predetermined assembly areas are identified in approved procedures and radiological surveys are completed as required by the TSC. The number of unaccounted individuals should be available within approximately 30 minutes for persons within the security area as defined in the Physical Security Plan.
If only a particular area is cleared, personnel in that area evacuate to a safe area. An accountability report is provided to the SED from Security. Further details of evacuation procedures are described in CRN-EPIPs.
If radiation levels or airborne radioactivity at an assembly point is significantly higher than alternative assemble areas, or the SED deems it necessary, the SED orders relocation to a safe assembly point. Employees are released from this assembly point when the SED determines it is suitable to do so.
Procedures require that all potentially contaminated people and vehicles pass through a Rad Protection check-point for survey prior to being released.
In the event of the evacuation of nonessential site personnel, the SED notifies the CECC Director. If the personnel require transportation and sheltering, the CECC Director coordinates arrangements with the appropriate State agency. If the evacuees require radiological decontamination, they are informed of transportation, sheltering, and decontamination arrangements prior to leaving the plant site. An alternate decontamination facility is specified in a CRN-EPIP.
Contaminated personnel are decontaminated to the limits specified in the CRN Site Radiological Control Instructions (RCIs) by methods described in the instructions before being released by TVA.
36 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Procedures also specify the action to be taken by, and the accountability of, personnel having an emergency assignment. Essential plant personnel remaining onsite are protected by plant systems designed to provide a habitable environment even under the most serious emergency conditions or by precautionary measures such as the use of respiratory protective equipment and protective clothing. Personnel doses are controlled in accordance with Section 11.0.
10.2 ONSITE PROTECTIVE ACTIONS FOR HOSTILE ACTION EVENTS A range of protective actions to protect onsite personnel during a Hostile Action event are developed to ensure the continued ability to safely shut down the reactor(s) and perform the functions of the Emergency Plan. This range of protective actions are contained in the CRN Site abnormal procedures. These procedures are classified security sensitive.
10.3 OFFSITE As addressed in the Federal Emergency Management Agencys (FEMA) Comprehensive Preparedness Guide 101, Developing and Maintaining Emergency Operations Plans (CPG-101), if determined appropriate, government officials may utilize a CEMP approach to emergency planning to implement ad hoc protective actions to protect the public.
37 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 11.0 RADIOLOGICAL PROTECTION The Radiological Protection Section at the CRN Site is responsible for Radiological Protection activities onsite. Its function is to develop instructions to implement the requirements of Title 10 Code of Federal Regulations, Part 20, and other required standards as well as the requirements and policies in TVA radiological control procedures. The Section provides surveillance during normal operation as well as emergency situations. In addition, the Section advises key plant personnel on radiological matters for routine and emergency conditions.
The limiting doses to occupational workers during routine plant operations are found in TVA radiological control procedures. If possible, TVA maintains these limits during emergency operations.
If these standards cannot be met during emergencies, TVA implements the dose guidance described in Table 11-1. A CRN-EPIP describes the methods to use and authorizes the doses outlined in Table 11-1. Table 11-2 describes the health effects of radiation doses greater than 25 RAD.
For individuals entering radiation work permit areas, electronic dosimeters and primary dosimeters are issued and read in accordance with the site TVA radiological control procedures. The electronic dosimeters can be read at any time. Primary dosimetry processing and evaluation is performed by an organization currently accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology for the type or types of radiation that most closely approximates the type of radiation or radiations for which the individual wearing the dosimeter is monitored. Dose records are maintained on each monitored individual by a computer.
TVA radiological control procedures contain the criteria used to establish contamination zones and to release personnel, equipment, and clothing. Onsite facilities are available to decontaminate equipment and personnel.
Procedures for using individual respiratory protection and protective clothing are provided in specific plant operating procedures. Procedures for the use of radioprotective drugs are provided in the EPIPs. Drinking water and eating controls are established by Radiation Protection.
Authorizations for emergency dose limits for TVA personnel is provided by the SED.
TVA implements adequate protective measures so that dose, considering both internal and external pathways, is maintained As Low As Reasonably Achievable (ALARA). Internal dose is minimized by the use of respiratory protection equipment consistent with maintaining the Total Effective Dose Equivalent (TEDE) ALARA, and protective clothing is used to minimize personnel contamination. If a projected dose to a workers thyroid is expected to exceed 10 rem during a radiological emergency, Potassium Iodide (KI) is issued in accordance with applicable implementing procedures.
Personnel shall not enter any area where dose rates are unknown or unmeasurable with either instruments or available dosimetry.
Receipt of emergency exposures in excess of 10 CFR 20.1201 limits shall be on a voluntary basis.
Personnel receiving emergency exposures shall be informed of the risks involved including the numerical levels of dose at which acute effects of radiation will be incurred, and numerical estimates of the risk of delayed effects. Table 11-2 provides information consistent with Environmental Protection Agency Protective Action Guides and Planning Guidance for Radiological Incidents (EPA PAG Manual), Draft for Interim Use and Public Comment, dated March 2013," which may be useful for this briefing purpose.
38 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Personnel receiving emergency doses should be restricted from further occupational exposure pending the outcome of exposure evaluations, and, if necessary, medical surveillance.
Any personnel dose in excess of five (5) rem TEDE shall be handled in accordance with the TVA Nuclear Radiological Protection Plan.
39 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
TABLE 11-1 EMERGENCY WORKER DOSE GUIDANCE TEDE Dose Condition 5 rem All, maintain dose ALARA 10 rem Protection of valuable property when lower dose not practicable.
25 rem Lifesaving or protection of large populations when lower dose not practicable.
Greater than 25 rem Lifesaving or protection of large populations when lower dose not practicable.
Only on a volunteer basis to persons fully aware of the risks involved.
NOTE: Situations may occur in which a dose in excess of regulatory limits (10 CFR 20.1201) would be required for plant and lifesaving operations. It is not possible to prejudge the risk that one person should be allowed to take in these situations. However, persons undertaking an emergency mission in which the dose would exceed regulatory limits should do so only on a voluntary basis and with full awareness of the risks involved (EPA PAG Manual, March 2013).
Guidance for dose to the lens of the eye is three (3) times the listed TEDE value. Dose to any other organ (including skin and body extremities) is ten (10) times the listed TEDE value.

41 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 12.0 MEDICAL SUPPORT 12.1 GENERAL INFORMATION Facilities, equipment, medical supplies, and trained personnel are available for first aid/emergency medical treatment of ill or injured persons onsite.
Guidance for medical assistance is found in a CRN-EPIP. Immediate lifesaving and disability limiting procedures take precedence over noncritical decontamination and dosimetry assessment measures.
When activated, the CECC coordinates the care, disposition, and reporting of injuries known or suspected to be associated with excess levels of radiation exposure or contamination. The purpose of the Medical Emergency Response Team (MERT) (team composition specified in a CRN Site procedure) is to:
Provide first aid/emergency medical treatment for ill or injured persons onsite, including those who may have been exposed to or contaminated with radioactive material.
Minimize injury during the rescue, treatment, and transport of injured persons, while minimizing radiological hazards and exposure to the victim.
Advise and protect attending personnel from unacceptable and unnecessary radiological hazards and exposures.
Identify, document, and control radiation exposure and contamination hazards associated with the emergency.
12.1.1 Classification And Handling Of Medical Emergency Patients 12.1.2 Noncontaminated-Nonirradiated When it is known that the patient is not contaminated and has not been overexposed to radiation, TVA handles the patient according to standard first aid/emergency medical protocol. The patient, ambulance crew, receiving hospital, and attending physician (as applicable) are advised of the absence of radiological complications.
12.1.3 Irradiated-Noncontaminated TVA coordinates the removal of the patient from the source of radiation exposure as soon as medical conditions and essential treatments permit. Continued medical care for physical injuries, including ambulance transport, is provided as indicated. Rad Protection determines and reports radiation exposure levels, including affected body areas. Emergency care for the radiation exposure is governed by the dose assessment and the medical status. Involved personnel are advised of the absence of radiological contamination.
42 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 12.1.4 Contaminated For patients known to be or suspected of being contaminated, TVA coordinates essential first aid and emergency medical care. Decontamination activities are accomplished as the medical status permits.
Involved personnel are advised of the contamination hazard. Continued care and decontamination decisions are made on an individual basis by the responsible medical care provider and Rad Protection.
12.2 TRANSPORTATION OF INJURED PERSONNEL The decision to transport a patient offsite is the responsibility of the emergency medical care provider performing patient assessment, i.e., Emergency Medical Technician (EMT) or Registered Nurse. If conflicting decisions arise, the option which provides the patient with the optimal level of medical care is chosen.
When ambulance transportation is indicated, transport may be provided by either the site Fire Protection EMTs (using a TVA ambulance) or by an agreement ambulance service. The MERT Team Leader coordinates requests for offsite ambulance assistance through the SM. The SM performs initial requests and notifications for assistance.
TVA maintains arrangements for one or more agreement ambulance services for the CRN Site with trained personnel to transport patients, including those who may have been exposed to or contaminated with radioactive material. These services are designated in a CRN-EPIP and letters of agreement for response are maintained. (See Section 16.5.)
12.3 INTERAGENCY ASSISTANCE FROM REAC/TS TVA maintains arrangements with the Radiation Emergency Assistance Center/Training Site (REAC/TS) as the CRN Site receiving hospital. REAC/TS, which is in close proximity to the CRN Site, is a DOE-sponsored facility operated by Oak Ridge Associated Universities Medical and Health Sciences Division in cooperation with the Oak Ridge Methodist Medical Center in Oak Ridge, Tennessee. The University of Tennessee Medical Center in Knoxville, Tennessee serves as a back-up to REAC/TS. Specialized facilities and expert personnel are available at both medical facilities for definitive care for radiation emergency victims. Letters of Agreement for services are maintained. (See Section 16.5.)
43 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 13.0 TERMINATION AND RECOVERY 13.1 TERMINATION The SM/SED is responsible for the decision to terminate an event for which the onsite and offsite emergency response facilities have not been activated.
In the event of an incident requiring activation of onsite and offsite emergency centers, the SED coordinates the decision to terminate the event with the CECC Director after consultation with the plant technical and operations staffs. This decision is based upon a comprehensive review of plant status and system parameters. These considerations include, but are not limited to, the following:
Stability of the reactor shutdown condition, i.e., successful progress toward a cold shutdown condition Integrity of the reactor containment building Operability of engineered safety systems and decontamination facilities Availability and operability of a heat sink Integrity of power supplies and electrical equipment Operability and integrity of instrumentation including radiation monitoring equipment (also including portable equipment assigned during the emergency)
Availability of trained personnel and support services Control of radiological effluent releases Decisions to relax protective measures for the public that may have been implemented will be made by the appropriate State representatives. The CECC Director provides information to the appropriate State agencies to facilitate the decision. The State has the authority and responsibility for offsite recovery efforts. TVA will provide assistance, as requested, through the recovery organization shown in Figure 13-1 (Figure 13-1 lists functions which must be addressed for recovery; the normal organizational titles may be different than what is represented here).
The CECC Director, after consultation with the State, the SED, and discussion with the NRC (if appropriate), announces that the emergency has terminated and the recovery phase is to be initiated, if appropriate. TVA then develops procedures and plans to implement the most expeditious recovery sequence to return the plant to normal operation.

48 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 14.0 DRILLS AND EXERCISES 14.1 DRILLS Drills are conducted to develop and maintain key skills required for emergency response. These drills may be conducted individually or as part of an REP exercise.
The following drills are required:
14.1.1 Medical Emergency Drills A medical emergency drill involving a simulated contaminated/injured individual, with participation by a TVA or agreement ambulance and each agreement hospital (see Section 16.5) is conducted each calendar year for the CRN Site. Scenario development, drill activities, and evaluations are jointly conducted and critiqued by EP and the site.
14.1.2 Radiological Monitoring Drills Environmental monitoring vehicle drills are conducted each calendar year for the CRN Site.
These drills include collection and analyses of sample media (i.e., water, air, grass, and/or soil as may be required by the scenario), direct radiation measurements, operation of vehicles, communication equipment, sampling equipment, and recordkeeping. The scenario is developed and the drills are conducted and critiqued by the site or EP.
14.1.3 Rad Protection Drills Rad Protection drills are conducted twice each calendar year for the CRN Site. These drills involve response to, and analysis of, simulated elevated airborne samples and direct radiation readings in the plant. The scenario is developed and the drills are conducted and critiqued by the site.
14.1.4 Radiochemistry Drills Radiochemistry drills are conducted each calendar year at the CRN Site. These drills involve collecting and analyzing in-plant liquid and gaseous samples containing actual or simulated elevated levels, including use or simulated use of the post-emergency sampling system. The scenario is developed and the drills are conducted and critiqued by the site.
14.1.5 Radiological Dose Assessment Drills Radiological dose assessment drills are conducted at least twice each calendar year to test the procedures, calculation techniques, computer codes, and environmental assessment abilities of the CECC staff and support groups. These scenarios are developed and the drills are conducted and critiqued by EP.
14.1.6 Fire Drills Fire drills are conducted at the CRN Site in accordance with, and as required by, specific procedural requirements.
49 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ) 14.1.7 Communication Drills Communications drills are conducted at least once each calendar year at the CRN Site.
14.2 EXERCISES Exercises are scheduled and conducted such that:
A biennial exercise will be conducted for the CRN Site to test the REP every 2 calendar years.
The CRN Site ensures that adequate emergency response capabilities are maintained during the interval between biennial exercises by conducting drills, including at least one drill involving a combination of some of the principal functional areas of the onsite emergency response capabilities. (The principal functional areas of emergency response include activities such as management and coordination of emergency response, emergency assessment, and plant system repair and corrective actions. During these drills supervised instruction is permitted, and activation of all of the emergency response facilities is not necessary. Sites have the opportunity to consider emergency management strategies, operating staff have the opportunity to resolve problems (success paths) rather than have controllers intervene, and the drills can focus on onsite training objectives. Sites shall enable the states and local authorities to participate in such drills when requested.)
TVA offers State and local authorities and support organizations the opportunity to participate in drills and exercises to the extent their assistance would be expected during an emergency at the CRN Site; however, participation is not required.
Major elements of the emergency plans and organizations are tested within an eight-year period.
The CRN Site initiates an exercise between 6:00 p.m. and 4:00 am at least once every eight years. The exact time of the exercise is unannounced.
14.3 SCENARIOS Drills and exercises are conducted in accordance with scenarios that have been properly planned, researched, and developed.
The drill and exercise scenarios include, but are not limited to, the following:
The basic objectives of each drill or exercise.
The date(s), time period, place(s), and participating organizations.
The simulated events.
A time schedule of real and simulated initiating events.
50 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
A narrative summary describing the conduct of the exercises or drill, including simulated casualties, offsite fire department assistance, rescue of personnel, use of protective clothing, deployment of radiological monitoring teams, and public information activities.
Drill scenario development and implementation is the responsibility of the organization responsible for the specific drill.
Exercise scenario development and implementation is the responsibility of EP. Scenario specifics are not released by those representatives prior to the exercise.
Exercise scenarios will be developed to thoroughly test the REP on an eight year cycle. The exact time of an exercise is not released; however, a time span within which the exercise is to occur may be supplied to appropriate organizations and the news media so that the exercise is not confused with an actual emergency.
In the event a remedial exercise is required, a scenario is developed to demonstrate corrective measures have been taken regarding the described deficiencies.
14.4 CRITIQUES Representatives of Quality Assurance, INPO, NRC, DHS, State/local agencies and others may observe the exercise. Additional evaluators may be requested from other organizations as necessary. Evaluators are provided with sufficient material and a briefing prior to the exercise to become familiar with the Emergency Plan and exercise scenario.
At the conclusion of each exercise, a critique is conducted where the exercise and its participants are evaluated for effectiveness, procedural compliance and good practices. EP evaluates critique comments, develops a formal written report, coordinates corrective actions for deficiencies or items needing improvement, and follows up to ensure completion of corrective actions.
Drill critiques, critique reports, coordination of corrective action and follow-up to ensure completion is the responsibility of the organization administering the drill.
51 Revision 1

64 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Attachment 1 Justification for the Central Emergency Control Center Under 10 CFR Part 50, Appendix E, Section IV.E.8, TVA is required to provide a licensee near-site Emergency Operations Facility (EOF) from which effective direction can be given and effective control can be exercised during an emergency. The NRC provides guidance for design and location of the EOF in NUREG-0696, Functional Criteria for Emergency Response Facilities (NUREG-0696). Since the early 1980s, TVA has used a centralized concept for providing the EOF function for its nuclear sites. Consistent with this approach, the CRN Site Emergency Plan relies on the use of the Central Emergency Control Center (CECC) as the EOF for the CRN Site. The CECC serves as the EOF for the other TVA nuclear plants (Browns Ferry Nuclear Plant (BFN), Sequoyah Nuclear Plant (SQN), and Watts Bar Nuclear Plant (WBN)). The CECC is located in the TVA Chattanooga Office Complex (COC) in Chattanooga, Tennessee, approximately 78 air miles from the CRN Site. The CECC is further than 20 miles from the CRN Site Technical Support Center (TSC), as is the case for BFN, SQN, and WBN, but does not alter the functions of the EOF as described in NUREG-0696.
The use of the CECC as the EOF for the CRN Site allows TVA to continue to operate a standardized program for corporate management and response to radiological emergencies at TVA nuclear facilities. The effectiveness of CECC operations has been demonstrated during numerous drills and exercises. Communications systems, data links, and staffing have been incorporated and tested. Using the CECC for the CRN Site also allows TVA to apply its corporate emergency response structure and experience to the CRN Site Emergency Plan.
TVA has discussed this concept with the Tennessee Emergency Management Agency (TEMA).
TEMA is familiar with the CECC because the facility is used for responding to radiological emergencies at SQN and WBN. Through the letter referenced in SSAR, Section 13.3 of the CRN ESPA, TEMA confirms their support of the TVA emergency response program, included the use of the CECC in Chattanooga.
Access to the station by the NRC site team is accommodated. The CRN Site has a Local Recovery Center (LRC) which is a pre-designated facility dedicated for use by offsite TVA and NRC personnel that may be assigned to the CRN Site for recovery operations. In addition, the LRC may be used by the NRC during the event as an area near the site for assessment and assistance and has the capability to communicate offsite. Additional information regarding the LRC can be found in section 8.1.3 of this Plan and in A.4.8 in Appendix A.
The CECC includes space for State liaisons reporting to the CECC in Chattanooga.
The following discussion provides an evaluation of the CECC against the criteria provided in NUREG-0696.
65 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Evaluation Against NUREG-0696:
The CECC is designed to provide for the effective and timely performance of the following functions:
Management of overall licensee emergency response.
Coordination of radiological and environmental assessment.
The primary role of the CECC is to relieve the plant staff of the functions of keeping the federal, State, and county emergency response organizations informed, for directing dose assessment and field monitoring, for managing the informational needs of the media, interested industry groups, and elected officials, and for supporting the emergency assessment needs of the TSC staff. The NRC will have access to plant data through the CECC computer system and the Emergency Response Data System (ERDS). The NRC also has telephones on the Emergency Telecommunications System (ETS) in Chattanooga.
Equipment exists in the CECC for the acquisition, display, and evaluation of radiological, meteorological, and plant system data. Because a similar set of data currently used for BFN, SQN, and WBN are required for the CRN Site, the plant and effluent data would be provided on as timely a basis at the CECC as it would be at a near-site location.
Normal industrial security is already provided for the CECC and processes are already established to upgrade the security of the facility during an activation.
Location, Structure, and Habitability The CECC is located in the northeast corner of the sixth floor of Lookout Place in the TVA COC in Chattanooga, Tennessee. The CECC has proven to be an effective facility for implementation of the TVA nuclear station emergency plans. The CECC is used for existing TVA nuclear plants at the BFN, SQN, and WBN sites. The facility is more than ten miles from any of the TVA nuclear stations; therefore, there are no specific habitability criteria.
Staffing and Training Incorporation of CRN emergency response functions into the CECC will not adversely affect the ability of TVA to staff the CECC in a timely manner. The CECC is staffed with experienced personnel from the TVA COC and personnel from one or more TVA nuclear plants. The CECC staff has demonstrated their ability to staff the CECC within required time-frames following emergency declaration during previous staff augmentation drills. The CECC staff includes personnel to manage overall licensee emergency response, and coordinate radiological and environmental assessment.
Size The CECC size has proven to be adequate during drills and exercises for the existing TVA nuclear facilities. In addition, the NRC has workspace co-located with the decision makers, radiological assessment, and emergency assessment personnel.
66 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Radiological Monitoring The CECC is beyond 10 miles from any nuclear stations, and therefore does not require radiological monitoring equipment.
Communications The communications systems available in the CECC consist of:
Central Office Trunks.
Tie-lines.
Digital Services.
Privately-owned/maintained microwave systems.
Privately-owned fiber-optic systems.
NRC ETS phones.
EP Radio System.
The emergency communications systems at the CECC are designed to provide a reliable, timely flow of information between the parties having an emergency response role. The single facility results in commonality of communications and interface with offsite officials and liaisons. The EP telephone system continues to be the primary means of communicating changes in event classification. This system operates on a combination of the TVA telecommunications network and leased circuits.
The offsite communications network is used to communicate with federal, State, and other supporting agencies. Access to these agencies is provided through several redundant, diverse routes. This diversity provides offsite routing through more than one type of facility. These facilities include, but are not limited to, commercial facilities such as central office trunks, tie-lines and digital services, plus privately owned and maintained microwave and fiber-optic systems. The offsite telecommunications network is designed to facilitate traffic in the most fail-safe manner to the emergency response organizations.
The Emergency Notification System (ENS) and Health Physics Network (HPN) (NRC FTS 2000 System) communication systems provide communications from each site TSC, Control Room, and the CECC to the NRC Headquarters and regional offices. These telephones are tested on a periodic basis consistent with the CRN Site Emergency Plan.
The EP radio system is a VHF mobile radio system which provides redundant radio coverage of the Plume Exposure Pathway (PEP) Emergency Planning Zone (EPZ) and provides radiological monitoring vehicles with mobile communications to other vehicle(s) and to the following locations: Radiological Control, TSC, Control Room at each TVA plant, and the CECC.
67 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Instrumentation, Data System Equipment, and Power Supplies Various plant parameters are available to the CECC staff via a connection through the TVA CECC computer network. Data available at the CECC provides a snapshot of data from each units integrated set of plant data. Plant data can be displayed at the CECC. These data are sufficient to perform emergency assessment and evaluate the potential environmental consequences of an emergency at the CRN Site. Detailed discussion on CRN Site plant-specific parameters are described in the Emergency Plan. The computers in the dose assessment area are capable of running the dose projection computer programs and accessing plant status data.
Hourly and 15-minute average meteorological data from the plant Environmental Data Station are available to the CECC, TSC, State, and LRC. The CECC computer system provides access to up to the most recent 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> of this data. A meteorologist in the CECC provides meteorological information to the CECC staff in support of offsite dose projections.
The CECC draws its primary power from commercial power. A loss of commercial power should not impact any of the voice or data communications equipment located in the CECC. Common TVA telecommunications infrastructure that supports CECC functions, including, but not limited to fiber optic transmission equipment, telephone switching equipment, and data network routers, is configured to operate from at least one and usually multiple backup power sources in the event of a loss of commercial power. These backup sources include generator, dc battery and uninterruptible power supply systems.
Technical Data and Data Systems As discussed in the previous section, a variety of plant parameters are provided over the TVA communications network to the CECC.
Reports Availability and Management Hard copies of key reference materials are maintained in the CECC. In addition, station design documentation, plant drawings, procedures, etc. are available via Local Area Network connection from the Business Support Library.
The following information is available for the CRN Site at the CECC:
Plant technical specifications.
Plant operating procedures.
Emergency operating procedures.
Final Safety Analysis Report.
Up-to-date licensee, State, and local emergency response plans.
68 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5A, Emergency Plan (Site Boundary EPZ)
Conclusion The CECC meets the functional and design criteria provided in NUREG-0696 for an EOF with the exception that it is located more than 20 miles from the CRN Site. This document describes the TVA approach to assuring that these functional and design criteria are met and maintained.
The consolidation of TVA corporate emergency response functions into a centralized facility provides a timely and effective response to a radiological emergency at the CRN Site.

Appendix A A.1 CLINCH RIVER NUCLEAR SITE AND EMERGENCY PLANNING ZONE DESCRIPTION A.1.1 FACILITY AND SITE CHARACTERISTICS A.1.1.1 Nuclear Power Facility The Clinch River Nuclear (CRN) Site is located on the Clinch River Property and is used as the location to construct and operate Small Modular Reactors (SMRs).
A.1.1.2 Site Location and Description The CRN Site Property covers an area of approximately 1,200 acres located adjacent to the Clinch River in Roane County, Tennessee. The CRN Site lies north of U.S. Interstate 40, approximately midway between the communities of Harriman and Farragut in the eastern portion of Tennessee.
Site Safety Analysis Report (SSAR) Chapter 2 provides additional information regarding the physical characteristics of the proposed site, including the preliminary site layout and potential hazards in the site vicinity. The Environmental Report provides detailed information addressing land use and other features of the proposed site and surrounding area.
A.1.2 EMERGENCY PLANNING ZONES Section 50.47(c)(2) of 10 CFR 50 establishes two Emergency Planning Zones (EPZs) for consideration in nuclear power plant emergency planning. For the CRN Site, the plume exposure pathway (PEP) EPZ encompasses the same area as the CRN site boundary. The ingestion exposure pathway EPZ encompasses an area that is yet to be determined. TVA intends to address this in the CRN Site Combined License Application (COLA). Of particular interest regarding the CRN Site is the overlapping emergency planning zone for the U.S.
Department of Energy (DOE) Oak Ridge Reservation.

SUPPLEMENTAL INFORMATION Evacuation Time Estimate Report vi Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 1.0 PURPOSE The purpose of Part 5B is to provide sufficient information to ensure the compatibility of the proposed emergency plans (for both onsite areas and the plume exposure and ingestion exposure pathway emergency planning zones) with facility design features, site layout, and site location. Part 5B, in conjunction with the Evacuation Time Estimate Report, addresses considerations such as access routes, population distributions, land use, and local jurisdictional boundaries. In an effort to maintain consistency throughout the fleet, the content of Part 5B is based on the Tennessee Valley Authoritys (TVA) Nuclear Power Radiological Emergency Plan (NP-REP), Generic Part, which has been approved by the U.S. Nuclear Regulatory Commission (NRC) for use at all of the TVA operating nuclear facilities. Site-specific information is included in Appendix A to this Plan to address emergency planning for the Clinch River Nuclear (CRN) Site. This Plan addresses pertinent requirements and associated guidance contained in NUREG-0654, Revision 1, Supplement 2, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants - Criteria for Planning in an Early Site Permit Application (NUREG-0654 Supplement 2), to provide major features of the Emergency Plan. Information that was not available to TVA during the development of the CRN Site Early Site Permit Application (ESPA) will be addressed in the Combined License Application (COLA). Information to be addressed at COLA includes analysis normally found in a Design Certification Application and not currently available such as specific accident development details, staffing levels, required safety-related equipment.
In accordance with 10 CFR Part 52, Early Site Permits; Standard Design Certifications; and Combined Licenses for Nuclear Power Plants, Part 5B addresses the emergency planning requirements of Appendix E to 10 CFR Part 50, Section III, the Final Safety Analysis Report; Site Safety Analysis Report. Part 50 Appendix E states, The final safety analysis report or the site safety analysis report for an early site permit that includes major features of emergency plans under 10 CFR 52.17(b)(2)(i) of this chapter shall contain the plans for coping with emergencies. In addition, these regulations require that the application must contain the means which the standards of § 50.47(b) will be met.
In the development of this Plan, TVA has considered the applicable guidance provided in the following documents with consideration given to the proposed exemptions contained in Part 6 of the ESPA:
- NUREG-0654, Revision 1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants (NUREG-0654).
- NUREG-0654, Revision 1, Supplement 2.
- NUREG-0654, Revision 1, Supplement 3, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants - Guidance for Protective Action Strategies (NUREG-0654).
- Regulatory Guide 1.101, Revision 3, Emergency Planning and Preparedness for Nuclear Power Reactors (RG 1.101).
1 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
- Section 13.3 of Regulatory Guide 1.70, Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants (LWR Edition) (RG 1.70).
- Section 13.3 of NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition (NUREG-0800).
As specified in NUREG-0654 and RG 1.101, this Plan provides for the following:
- Adequate measures are taken to protect employees and the public.
- Individuals having responsibilities during an emergency are properly trained.
- Procedures exist to provide the capability to cope with a spectrum of emergencies ranging from those of little consequence to major core melt.
- Equipment is available to detect, assess, and mitigate the consequences of such occurrences.
- Emergency action levels and procedures are established to assist in making decisions.
This Plan has been developed to respond to potential radiological emergencies at the CRN Site as they may apply to small modular reactors (SMRs). As discussed in Site Safety Analysis Report (SSAR) Section 13.3 of this EPSA, the SMR technologies under consideration do not have postulated design basis accidents that would result in dose consequences that are large enough to require offsite emergency planning, the overall scope of this plan delineates the actions necessary to safeguard onsite personnel (within the site boundary) and minimize damage to property. As discussed in Part 3 of this ESPA, for postulated beyond design basis accidents, analysis has concluded that, because of the slow progression rate, sufficient time is available to initiate appropriate mitigating actions to protect the health and safety of the public beyond the Site Boundary.
The NRC requires a level of emergency preparedness commensurate with the potential consequences to public health, safety, common defense, and security at the CRN Site. This Plan considers the proposed exemptions contained in Part 6 of the ESPA. Implementation of this Plan is not dependent on the comprehensive emergency management plan (CEMP) nor would TVA impose a requirement on offsite agencies to implement this Plan.
The CRN Site ESPA (Part 5B, Emergency Plan) consists of this Generic Part and the site specific Appendix A. Appendix A is complementary with the State plan referenced in Appendix A, Attachment 1.
2 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 2.0 SCOPE This Plan provides information regarding emergency preparedness and response planning for the CRN Site and addresses organizational responsibilities, capabilities, actions, and guidelines for TVA during a radiological emergency. It also describes the centralized emergency management concept which was approved by the NRC Commissioners via COMJA-80-37 (January 21, 1981). Additional guidance regarding the centralized emergency management concept can also be found in NRC SECY-96-170 (August 5, 1996) and NRC SECY-10-0078 (June 16, 2010).
2.1 APPENDICES Additional Radiological Emergency Plan information specific to the CRN Site is included as the CRN Site ESPA (Part 5B, Emergency Plan / Appendix A); referred to in the remainder of this document as Appendix A.
Appendix A details facility features, capabilities, equipment, and responsibilities. The Generic Part together with Appendix A, describes the methods TVA will use to:
- 1. Detect an emergency condition.
- 2. Evaluate the severity of the problems.
- 3. Notify federal, State, and local agencies of the condition.
- 4. Activate emergency organizations.
- 5. Evaluate the possible offsite consequences.
- 6. Recommend protective actions for the public.
- 7. Mitigate the consequences of the emergency.
Since TVAs authority is limited to TVA-owned and controlled property, the State of Tennessee (State) and local agencies are responsible for ordering and implementing actions offsite to protect the health and safety of the public. Appendix A, Attachment 1 references the State Plan which supplements this Plan.
2.2 IMPLEMENTING PROCEDURES TVA develops specific procedures to ensure that the Plan is implemented as designed. These implementing procedures are designed to ensure that emergencies are properly evaluated, rapid notifications made, and assessment and protective actions performed. These procedures are compiled in the Emergency Plan Implementing Procedures (EPIPs). Site specific procedures for abnormal and emergency operation and control exist but are not included in the EPIPs. These plant operating procedures are designed to ensure the implementation of the EPIPs.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 2.4 NATIONAL RESPONSE FRAMEWORK The National Response Framework (NRF) Nuclear/ Radiological Incident Annex provides for timely, coordinated response by federal agencies to a fixed nuclear power plant facility incident.
The NRF is activated by either the affected State notifying the Department of Homeland Security (DHS), or the utility notifying the NRC of a radiological emergency at a nuclear plant site. The NRF is not included as part of the TVA Radiological Emergency Plan. Should additional radiological monitoring support be required, the appropriate State agency will make the request through DHS. The persons authorized to request this assistance, the specific resources expected, and resources available to support the federal response are provided in the respective State plans.
The NRF may be used by federal agencies in radiological emergencies. The NRF primarily concerns offsite federal response in support of State and local governments with jurisdiction for the emergency. The NRF provides the federal government's concept of operations for responding to radiological emergencies, outlines federal policies and planning assumptions, and specifies authorities and responsibilities of each federal agency that may have a significant role in such emergencies. The Central Emergency Control Center (CECC) Director is the TVA representative authorized to request federal assistance. Such a request from TVA will be made to the NRC.
TVA will utilize the CECC in Chattanooga Tennessee as the Emergency Operations Facility (EOF) for the Clinch River Nuclear Site. The CECC serves as the EOF for the other TVA nuclear plants (Browns Ferry Nuclear Plant (BFN), Sequoyah Nuclear Plant (SQN), and Watts Bar Nuclear Plant (WBN)). This multi-site EOF was previously approved for use by the NRC in COMJA-80-37. Attachment 1 of this Plan provides additional description of and justification for the location of the CECC.
Because of the close proximity of the U.S. Department of Energy (DOE) Oak Ridge Reservation to the CRN Site, DOE response, should assistance be requested, is expected within 1 to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
Additional information about the NRF and available support is provided in NRC RIS 2005-13, NRC Incident Response and the National Response Plan (RIS 2005-13), NUREG-0728, Emergency Preparedness and Incident Response Programs (NUREG-0728) or the FEMA website (www.fema.gov) as well as in the Agency Emergency Response Plan (TVA-SPP-35.01).
5 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 3.0 PROCESS 3.1 ROLES AND RESPONSIBILITIES The development, implementation, and maintenance of the NP-REP is the responsibility of the TVA Nuclear organization. The General Manager, Support Services has delegated the authority for overall program control of the NP-REP to the Director, Emergency Preparedness as described below. Appendix A provides detailed staffing and organizational roles and responsibilities for the CRN Site minimum required Onsite Emergency Management Organization positions.
3.1.1 Emergency Management Organization (Concept of Operations)
The CRN Site Emergency Management Organization is divided into two categories; the Onsite Organization and the Offsite Emergency Organization. A block diagram of the Onsite Organization is presented in Appendix A and the Offsite Emergency Organization is presented in Figure 3-1. Emergency Management Organization personnel are required to participate in the Fitness for Duty Program.
The Onsite Organization is comprised of the Site Emergency Director (SED) and technical staff located in the Technical Support Center (TSC), a Control Room staff of Operations personnel, and additional support personnel located in the Operations Support Center (OSC). The Onsite Organization is responsible for the onsite response to an emergency condition. Onsite activities are directed by the SED to include such functions as Control Room operations, technical assessment, emergency mitigation analysis, onsite radiation surveys, and dose tracking for site personnel.
The Offsite Organization is designated as the CECC staff. The CECC staff is comprised of a CECC Director, a supporting group of technical assistants, and representatives of other TVA organizations. The CECC Director and supporting technical assistants report to the CECC during an emergency as required. Other TVA organizations will send representatives to the CECC as requested by the CECC Director.
The CECC is responsible for directing and coordinating the overall TVA response to an emergency condition. Functions such as offsite radiological monitoring and dose assessment, public information, State and local government coordination, and additional plant assessment are handled by the CECC relieving the Onsite Organization of the many peripheral duties necessary for the successful emergency response.
3.2 ONSITE ORGANIZATION Under normal conditions the Site Vice President is in charge of activities at the site and the Plant Manager is responsible for the safe efficient operation of the plant. The person primarily responsible for mitigation of an emergency is the SED. Upon declaration of an emergency the Shift Manager (SM) on duty initially fills the position of SED and directs emergency response from the Control Room. This position is transferred to the TSC when that facility is activated.
Once the TSC is activated, the SED and the TSC can provide technical support to the Control Room as part of their overall response to the emergency.
6 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
The CRN Site is staffed on a continual 24-hour basis. The minimum staffing requirements for plant operations are established in the plant Technical Specifications. The staff responsibilities are as outlined in the SSAR, and are unchanged during an emergency. The on-shift composition listed in Appendix A may be less than the minimum requirements for a period of time in order to accommodate unexpected absences of personnel provided action is taken to restore the composition within established time requirements.
Under emergency conditions, the normal plant staff is supplemented as shown in Appendix A.
Appendix A also provides descriptions of the responsibilities of the personnel who augment the normal plant operating organization. Support personnel will be notified to report as required by the situation. Staffing time for the augmenting forces is indicated in Appendix A. This time could vary slightly, depending upon the time of day, weather conditions, immediate availability of personnel, and radiological conditions.
The Onsite Organization augments the shift operations crew. If members of the Onsite Organization are not present when an emergency occurs, the SM on-duty, or a designated Unit Supervisor when acting as the SM, is designated the SED and acts as such until relieved by the SED assigned to the TSC.
Upon detection of a known or suspected emergency, the SM on-duty refers to a CRN-EPIP to determine the classification of the emergency. After determining the classification of the incident, the SM assumes the responsibilities of SED and initiates the appropriate procedure referenced by the CRN-EPIP. Emergency communications / notifications with State, local and federal agencies, along with staffing instructions for the emergency response facilities are specified in CRN-EPIPs.
CRN-EPIPs designate personnel who staff the Emergency Notification System (ENS) and Health Physics Network (HPN) (NRC FTS 2000 System) Communication Systems. CRN-EPIPs also designate the interface with the NRC during TSC operation.
3.3 OFFSITE ORGANIZATION Figure 3-1 provides a diagram of the Offsite Organization, including those positions that must respond within a prescribed time of an Alert or higher (see Section 4.0, Emergency Conditions) emergency declaration at the CRN Site. The prescribed response times for the Offsite Organization will be addressed in the COLA.
Activation for the CECC is accomplished within a prescribed time following declaration of an Alert or higher (see Section 4.0, Emergency Conditions) emergency classification at the CRN Site, depending upon time of day, weather conditions, or immediate availability of personnel.
The prescribed activation time for the CECC for an event at the CRN Site will be addressed in the COLA.

Figure 3-1 Offsite Emergency Organization 15 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 4.0 EMERGENCY CONDITIONS 4.1 CLASSIFICATION SYSTEM TVA utilizes the following emergency classifications:
- Notification of Unusual Event (NOUE)
- Alert
- Site Area Emergency
- General Emergency This system of classification is consistent with the systems used by State and local emergency organizations. The emergency classifications are graded according to severity and immediate actions are taken to cope with the situation. Escalation to a higher class, or termination, occurs during the course of an emergency if warranted by conditions. Examples of plant conditions and their recommended emergency classes are given in the CRN-EPIPs. These procedures also specify the initial prompt notifications, information, and recommendations to be provided to State and local emergency organizations. Examples of Initiating Conditions (ICs) and specific instrument readings, if appropriate for the various classifications, are provided in the EPIPs.
4.1.1 NOUE This classification provides early and prompt notification of events that are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.
The purposes of the NOUE are: (1) to ensure that the first steps in activating emergency organizations have been carried out; and (2) to provide current information on the unusual event.
TVA maintains the NOUE classification until closeout or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.1.2 Alert An Alert classification is indicated when events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of Hostile Action. Any releases are expected to be limited to small fractions of the Environmental Protection Agency (EPA) Protective Action Guides (PAG) exposure levels.
16 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
The purposes of the Alert classification are: (1) to ensure that emergency personnel are readily available to respond if the situation becomes more serious or to perform confirmatory radiation monitoring, if required; and (2) to provide offsite authorities current status information.
TVA maintains the Alert class until event termination or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.1.3 Site Area Emergency A Site Area Emergency is indicated when events are in process or have occurred which involve an actual or likely major failures of plant functions needed for protection of the public or Hostile Action that results in intentional damage or malicious acts: (1) toward site personnel or equipment that could lead to the likely failure of or; (2) that prevent effective access to equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA PAG exposure levels beyond the site boundary.
The purposes of the Site Area Emergency classification are: (1) to ensure that emergency response centers are staffed; (2) to assure that monitoring teams are dispatched; (3) to assure that personnel required for evacuation of near-site areas are at duty stations if the situation becomes more serious; and (4) to provide current information for, and consultation with, offsite authorities and the public.
TVA maintains the Site Area Emergency classification until event termination or escalation to a higher class. TVA notifies the State authorities and the NRC. The State notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.1.4 General Emergency A General Emergency is indicated when events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity or Hostile Action that results in an actual loss of physical control of the facility. Due to the SMR design, releases can be reasonably expected to exceed EPA PAG exposure levels offsite for more than the immediate site area.
The purposes of the General Emergency classification are: (1) to initiate predetermined protective actions for the public; (2) to provide continuous assessment of information from the site and offsite; and (3) to initiate additional measures as indicated by releases or potential releases of radioactivity.
When a General Emergency is declared, TVA recommends that State and local organizations implement protective actions as specified in the EPIPs.
17 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
TVA maintains the General Emergency until event termination. TVA notifies the State authorities and the NRC. The State notifies local authorities unless the initial classification is General Emergency, in which case TVA initially notifies the local authorities. Following closeout, TVA provides a briefing to State authorities. TVA provides a written summary of significant events to the State no later than the next working day.
4.2 IDENTIFICATION OF EMERGENCY CLASSES TVA uses a variety of methods to identify emergency situations and to categorize them. As indicated in the CRN-EPIPs, emergencies can be caused by natural disasters such as tornadoes or floods, hazards such as aircraft crashes, releases of toxic gases, or breaches of plant security, as well as by conditions involving plant systems directly.
Recognition of the emergency class is primarily a judgment matter for plant personnel. The ICs used for recognizing and declaring the emergency class are based on specific measurable values or observable conditions defined as Emergency Action Levels (EALs). These can be combinations of specific instrument readings (including their rates of change), annunciator warnings, time periods certain conditions exist, etc. The instrument readings and parameters required for determination of these EALs are detailed in the CRN-EPIPs. TVA uses these EALs as thresholds for determining the emergency classifications. The EALs are reviewed annually by the State.
TVA maintains the capability to assess, classify, and declare an emergency condition within 15 minutes after the availability of indication to plant operators that an emergency action level has been exceeded and to promptly declare the emergency condition upon identification of the appropriate EAL.
18 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 5.0 EMERGENCY NOTIFICATION AND ACTIVATION OF PLAN Emergency measures are developed to aid in the mitigation of emergency conditions.
Emergency measures begin with the declaration of an emergency class and activation of associated emergency organizations. These measures, which will include actions for assessment, correction, and protection, are described in general terms for each emergency class in the following parts of this section. Details of these emergency measures will be found in the appropriate sections of the CRN-EPIPs.
When the Plan is activated, TVA initiates certain predetermined actions. Notification is carried out as shown in Figure 5-1 to alert emergency staff personnel to handle the emergency situation.
5.1 ONSITE Upon detection of a known or suspected emergency, the SM on-duty will utilize a CRN-EPIP to determine the classification of the emergency. After determining the classification of the emergency, the SED will initiate the appropriate procedures referenced by the CRN-EPIP. Each procedure referenced by the CRN-EPIP gives specific instructions on staffing the TSC and the OSC and for notifying appropriate State authorities, the ODS, and the NRC.
5.2 OFFSITE Implementing procedures are provided to activate TVA and State emergency staffs. Essential emergency positions are covered on a 24-hour-a-day basis by duty personnel. Emergency response facilities are located to ensure rapid and effective response of personnel needed to assess and evaluate offsite conditions.
5.2.1 NOUE Upon declaration of this classification, TVA initiates the following actions:
A. The Control Room notifies and relays the information to the State within 15 minutes of declaration of the event. TVA utilizes a dedicated ring-down phone to make this notification.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 9.0 ACCIDENT ASSESSMENT 9.1 ONSITE In-plant accident assessment actions are carried out by the plant emergency staff in order to properly characterize and classify the emergency, determine the actual or potential radioactivity releases, and determine the effect on plant personnel and the public.
Assessment methodology consists of actions carried out through plant operating procedures as well as CRN-EPIPs. At the onset of an emergency, plant operating procedures (normal, abnormal, and emergency) assist the plant operator and SED in identifying the cause of the emergency, actions necessary to control the emergency, radioactivity release rate, if any, and in-plant radiation levels. The CRN-EPIPs assist the SED in: (1) identifying and reassessing emergency classification; (2) determining the need for offsite protective actions; (3) determining the need for plant area evacuation; (4) initiating activation of onsite and offsite emergency organizations; (5) directing the utilization of needed medical and/or decontamination facilities; and (6) implementing predetermined security and access control plans.
Each of the above-mentioned activities is described within the plant operating procedures or CRN-EPIPs, as applicable, for a given situation. The distinct breakdown of assessment actions into operating procedures and implementing procedures is necessary since some assessment actions are necessarily carried out prior to identification or classification of an emergency. The procedures to ensure that emergencies are properly evaluated, timely notifications are made, and assessment and protective actions are performed, are compiled in the CRN-EPIPs. These procedures are summarized by topic in Appendix A, Attachment 1.
Under severe emergency conditions, and as required by the plant emergency operating procedures, the onsite Emergency Management Organization is responsible for recognition of severe emergency conditions, transition to, and implementation of the Severe Accident Management Guidelines (SAMGs).
9.2 OFFSITE 9.2.1 General Information TVA and State agencies are prepared to assess the consequences of potential or actual releases of radioactivity offsite. State and local agencies implement protective actions for the public. Written messages have been prepared which give the public instructions with regard to specific protective actions to be taken by occupants of affected areas. These messages are included in the State Plan referenced in Appendix A, Attachment 1.
Implementing procedures have been developed for the CECC to ensure that emergencies are properly evaluated, timely notifications are made, and assessment and protective actions are performed. Once an SMR technology is selected, the details on staffing levels, response times, and accident progression rates will be known and can then be reflected in a set of EPIPs similar to the following list:

These vehicles are dispatched for environmental monitoring for Site Area Emergency and General Emergency classifications. TVA may deploy these vehicles for the NOUE and Alert classifications, if warranted. One or more vehicles is stationed at the CRN Site.
Each sampling team has the capability to:
- Obtain environmental samples for analysis.
- Make direct radiation readings.
- Collect air samples and analyze them for gross beta-gamma radioactivity over a range of energies.
- Collect air samples and analyze them for radioiodine in the field, to concentrations as low as 10-7 microcuries/cc.
CRN-EPIPs describe the composition and activation of sampling teams.
For the Site Area Emergency and General Emergency classifications, teams are dispatched from the nearest location. Teams may be deployed for the NOUE or Alert, if warranted. If necessary, TVA can coordinate team transport via helicopter or fixed-wing aircraft.
The TSC Rad Protection Manager or CECC Environs Assessor can request assistance from a neighboring plant for environmental monitoring, if deemed necessary.
TVA has aquatic monitoring teams located at Chattanooga, Tennessee, and Knoxville, Tennessee. These teams have boats that can be deployed to obtain samples from the river for subsequent analysis for radioactivity in the laboratories.
33 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
State agencies have the responsibility to coordinate and evaluate offsite assessment actions.
Environmental monitoring activities are coordinated through the RMCC. State environmental monitoring capabilities and the RMCC operations are referenced in Appendix A, Attachment 1.
TVA personnel are co-located in the RMCC, which provides for coordination of TVA and State monitoring teams. TVA and the State share environmental monitoring data.
Additional environmental monitoring assistance is available from the DOE offices at Oak Ridge, Tennessee, or Aiken, South Carolina. The EPA in Montgomery, Alabama, can also provide assistance. Available support includes environmental monitoring teams and mobile radioanalytical laboratories. The State agencies usually request and coordinate these services.
9.2.3 Analyzing Environmental Samples The sampling teams may send samples to the WARL for analysis. The WARL has the capability to perform further quantitative and qualitative analysis. The WARL is available as needed and can be operated 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day. The WARL can establish a central point for receipt of samples when needed.
9.2.4 Meteorological Information 9.2.4.1 Primary Meteorological Measurements TVA has developed the meteorological measurements program to conform to the intent and guidance of Regulatory Guide 1.23, Meteorological Monitoring Programs for Nuclear Power Plants (RG 1.23). Wind direction, wind speed, and air temperature are measured at two levels.
The temperature difference is used to estimate the Pasquill stability class. Precipitation and dew point temperature are also measured. Hourly and 15-minute average meteorological data from the plant Environmental Data Station are available to the CECC, TSC, State, and LRC. More specific information on the meteorological measurements program can be found in Section 2.3 of the CRN SSAR.
9.2.4.2 Backup Meteorological Data Estimation Procedures TVA has prepared objective backup procedures to provide estimates for missing or garbled data needed to perform dose calculations and to determine transport estimates. They incorporate available onsite and offsite data. Each procedure has an accompanying statement of reliability.
9.2.4.3 Real Time and Forecast Meteorological Data The CECC Meteorologist has the responsibility for providing meteorological information to CECC Staff. The dose assessors use this meteorological information to project offsite doses.
Plume positions are plotted on a site area map. The meteorological support actions and projection of doses are discussed in detail in CECC-EPIPs. Meteorological support may be provided in the CECC or from a remote location.
34 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 9.2.4.4 Remote Access of Meteorological Data Access of up to the most recent 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> of 15-minute and hourly meteorological data is available to authorized users through the CECC computer. The remote access system gathers data from the CRN Site, performs unit conversion, reformats data, and flags questionable values.
9.2.5 Dose Assessment On-shift dose assessment capability is maintained at the CRN Site, and can be implemented (if needed during the initial phase of an emergency) until the CECC is activated and assumes the dose assessment function.
Offsite doses from emergency-related releases of radioactivity are estimated using a combination of calculations, field measurements, and laboratory analyses of environmental samples. Data on meteorological conditions are used in determining offsite dispersion factors.
Using plant operational data, field measurements, and effluent monitor readings, actual or potential releases of radioactivity are analyzed by the plant staff, the Radiological Assessment staff, or the CECC Plant Assessment Team to generate or modify a source term for use in the dose assessment.
With this information, the CECC dose assessment team can predict offsite doses through the use of several models and/or methods described in the CECC-EPIPs. These models provide a means of estimating public exposures throughout the emergency and recovery period. Environs measurements are used, to the extent possible, to confirm doses projected by modeling.
A preliminary dose projection is performed following receipt of measured effluent release data (the source term) and meteorological data. The preliminary dose projection is followed up by a more detailed assessment using computerized dose models. Manual dose assessment methods are available for use in the event that the computer is unavailable. Input to the detailed calculations includes measured source terms, projected future releases, near real-time and forecast meteorological data, field measurements of exposure rates and/or airborne radioactivity in the environs around the plant, or a combination thereof. Field measurements are used to estimate doses, and (especially in the case of an unmonitored release) source terms, and to verify doses projected using models.
After termination of emergency-related releases to the atmosphere, integrated doses are calculated to assist in recovery/reentry operations. A combination of inputs including results from modeling field exposure rate and air concentration measurements and laboratory analyses of soil, vegetation, and water samples are used to assess doses. Recommendations are made regarding evacuation area clearance and reentry based on doses calculated for exposure from ground contamination, inhalation of re-suspended radioactivity, and ingestion of radioactivity in vegetables and milk.
35 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 10.0 PROTECTIVE RESPONSE 10.1 ONSITE PROTECTIVE ACTIONS FOR RADIOLOGICAL EVENTS In the event of an unplanned significant release of radioactivity or sudden increase in radiation levels, it is the responsibility of the SED to make the decision concerning the necessity for building and area evacuation. In arriving at this decision, the primary consideration is personnel safety. The SED may use the various radiation and airborne radioactivity monitors placed throughout the plant, with readout in the Control Room, to assess the extent of the radiological hazards and to determine the extent of evacuation necessary.
The assembly/accountability alarm is used to initiate the assembly of site personnel. The public address system is used if only specific areas are to be evacuated. Nuclear Security Services personnel patrol the area between the security boundary described in the Physical Security Plan and the Site Boundary, and evacuate any nonessential personnel.
Upon hearing the emergency alarm, persons in the plant areas proceed to their pre-assigned areas to be accounted for and await further instructions from the SED. The pre-assigned areas are designated in approved procedures. Predetermined assembly areas are identified in approved procedures and radiological surveys are completed as required by the TSC. The number of unaccounted individuals should be available within approximately 30 minutes for persons within the security area as defined in the Physical Security Plan.
If only a particular area is cleared, personnel in that area evacuate to a safe area. An accountability report is provided to the SED from Security. Further details of evacuation procedures are described in CRN-EPIPs.
If radiation levels or airborne radioactivity at an assembly point is significantly higher than alternative assemble areas, or the SED deems it necessary, the SED orders relocation to a safe assembly point. Employees are released from this assembly point when the SED determines it is suitable to do so.
Procedures require that potentially contaminated people and vehicles pass through a Rad Protection check-point for survey prior to being released.
In the event of the evacuation of nonessential site personnel, the SED notifies the CECC Director. If the personnel require transportation and sheltering, the CECC Director coordinates arrangements with the appropriate State agency. If the evacuees require radiological decontamination, they are informed of transportation, sheltering, and decontamination arrangements prior to leaving the plant site. An alternate decontamination facility is specified in a CRN-EPIP.
Contaminated personnel are decontaminated to the limits specified in the CRN Site Radiological Control Instructions (RCIs) by methods described in the instructions before being released by TVA.
36 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Procedures also specify the action to be taken by, and the accountability of, personnel having an emergency assignment. Essential plant personnel remaining onsite are protected by plant systems designed to provide a habitable environment even under the most serious emergency conditions or by precautionary measures such as the use of respiratory protective equipment and protective clothing. Personnel doses are controlled in accordance with Section 11.0.
10.2 ONSITE PROTECTIVE ACTIONS FOR HOSTILE ACTION EVENTS A range of protective actions to protect onsite personnel during a Hostile Action event are developed to ensure the continued ability to safely shut down the reactor(s) and perform the functions of the Emergency Plan. This range of protective actions are contained in the CRN Site abnormal procedures. These procedures are classified security sensitive.
10.3 OFFSITE Should an event be initially classified as a General Emergency, the SED has the responsibility to determine an initial protective action for recommendation to State and local government agencies. CRN-EPIPs provide a logic diagram as a decisional aid to facilitate this recommendation.
After the CECC is staffed, the responsibility for PARs is transferred to the CECC Director. The CECC Plant Assessment Manager provides an assessment of actual and projected plant conditions. The RAM provides an assessment of actual and/or projected radiological conditions offsite. The RAM also provides a recommendation for a specific protective action. The CECC Director evaluates the recommendation from staff and make a recommendation to the State.
The logic diagram for PEP recommendations is provided in the CECC-EPIPs as a decisional aid to facilitate the recommendation.
The State and local agencies are responsible for implementing actions to protect the health and safety of the public offsite. Although TVA may recommend protective actions to these agencies, the State and local governments are responsible for deciding if any actions are needed and what they should be. The CECC will discuss and provide ingestion exposure pathway recommendations (i.e., agricultural) and recommendations for liquid releases (i.e., closing of public water supplies) with the State as appropriate.
The decision to implement one or more of the above actions is based upon some or all of the following considerations:
- Projected offsite integrated doses.
- Actual measured dose rates.
- Present and future weather conditions.
- Projected improvement or deterioration of plant conditions.
- State protective action guides.
- Levels of airborne radioactivity.
37 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
- Levels of waterborne radioactivity.
- Concentrations of radioactivity in items for human consumption.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 11.0 RADIOLOGICAL PROTECTION The Radiological Protection Section at the CRN Site is responsible for Radiological Protection activities onsite. Its function is to develop instructions to implement the requirements of Title 10 Code of Federal Regulations, Part 20, and other required standards as well as the requirements and policies in TVA radiological control procedures. The Section provides surveillance during normal operation as well as emergency situations. In addition, the Section advises key plant personnel on radiological matters for routine and emergency conditions.
The limiting doses to occupational workers during routine plant operations are found in TVA radiological control procedures. If possible, TVA maintains these limits during emergency operations. If these standards cannot be met during emergencies, TVA implements the dose guidance described in Table 11-1. A CRN-EPIP describes the methods to use and authorizes the doses outlined in Table 11-1. Table 11-2 describes the health effects of radiation doses greater than 25 RAD.
For individuals entering radiation work permit areas, electronic dosimeters and primary dosimeters are issued and read in accordance with the site TVA radiological control procedures.
The electronic dosimeters can be read at any time. Primary dosimetry processing and evaluation is performed by an organization currently accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology for the type or types of radiation that most closely approximates the type of radiation or radiations for which the individual wearing the dosimeter is monitored. Dose records are maintained on each monitored individual by a computer.
TVA radiological control procedures contain the criteria used to establish contamination zones and to release personnel, equipment, and clothing. Onsite facilities are available to decontaminate equipment and personnel.
Procedures for using individual respiratory protection and protective clothing are provided in specific plant operating procedures. Procedures for the use of radioprotective drugs are provided in the EPIPs. Drinking water and eating controls are established by Radiation Protection.
Authorizations for emergency dose limits for onsite personnel is provided by the SED while authorizations for offsite personnel is provided by the CECC Radiological Assessment Manager.
TVA implements adequate protective measures so that dose, considering both internal and external pathways, is maintained As Low As Reasonably Achievable (ALARA). Internal dose is minimized by the use of respiratory protection equipment consistent with maintaining the Total Effective Dose Equivalent (TEDE) ALARA, and protective clothing is used to minimize personnel contamination. If a projected dose to a workers thyroid is expected to exceed 10 rem during a radiological emergency, Potassium Iodide (KI) is issued in accordance with applicable implementing procedures.
Personnel shall not enter any area where dose rates are unknown or unmeasurable with either instruments or available dosimetry.
39 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Receipt of emergency exposures in excess of 10 CFR 20.1201 limits shall be on a voluntary basis. Personnel receiving emergency exposures shall be informed of the risks involved including the numerical levels of dose at which acute effects of radiation will be incurred, and numerical estimates of the risk of delayed effects. Table 11-2 provides information consistent with Environmental Protection Agency Protective Action Guides and Planning Guidance for Radiological Incidents (EPA PAG Manual), Draft for Interim Use and Public Comment, dated March 2013," which may be useful for this briefing purpose.
Personnel receiving emergency doses should be restricted from further occupational exposure pending the outcome of exposure evaluations, and, if necessary, medical surveillance.
Any personnel dose in excess of five (5) rem TEDE shall be handled in accordance with the TVA Nuclear Radiological Protection Plan.

Greater than 25 rem Lifesaving or protection of large populations when lower dose not practicable.
Only on a volunteer basis to persons fully aware of the risks involved.
NOTE: Situations may occur in which a dose in excess of regulatory limits (10 CFR 20.1201) would be required for plant and lifesaving operations. It is not possible to prejudge the risk that one person should be allowed to take in these situations. However, persons undertaking an emergency mission in which the dose would exceed regulatory limits should do so only on a voluntary basis and with full awareness of the risks involved (EPA PAG Manual, March 2013).
Guidance for dose to the lens of the eye is three (3) times the listed TEDE value. Dose to any other organ (including skin and body extremities) is ten (10) times the listed TEDE value.

42 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 12.0 MEDICAL SUPPORT 12.1 GENERAL INFORMATION Facilities, equipment, medical supplies, and trained personnel are available for first aid/emergency medical treatment of ill or injured persons onsite.
Guidance for medical assistance is found in a CRN-EPIP. Immediate lifesaving and disability limiting procedures take precedence over noncritical decontamination and dosimetry assessment measures.
When activated, the CECC coordinates the care, disposition, and reporting of injuries known or suspected to be associated with excess levels of radiation exposure or contamination. The purpose of the Medical Emergency Response Team (MERT) (team composition specified in a CRN Site procedure) is to:
- Provide first aid/emergency medical treatment for ill or injured persons onsite, including those who may have been exposed to or contaminated with radioactive material.
- Minimize injury during the rescue, treatment, and transport of injured persons, while minimizing radiological hazards and exposure to the victim.
- Advise and protect attending personnel from unacceptable and unnecessary radiological hazards and exposures.
- Identify, document, and control radiation exposure and contamination hazards associated with the emergency.
12.2 CLASSIFICATION AND HANDLING OF MEDICAL EMERGENCY PATIENTS 12.2.1 Noncontaminated-Nonirradiated When it is known that the patient is not contaminated and has not been overexposed to radiation, TVA handles the patient according to standard first aid/emergency medical protocol.
The patient, ambulance crew, receiving hospital, and attending physician (as applicable) are advised of the absence of radiological complications.
12.2.2 Irradiated-Noncontaminated TVA coordinates the removal of the patient from the source of radiation exposure as soon as medical conditions and essential treatments permit. Continued medical care for physical injuries, including ambulance transport, is provided as indicated. Rad Protection determines and reports radiation exposure levels, including affected body areas. Emergency care for the radiation exposure is governed by the dose assessment and the medical status. Involved personnel are advised of the absence of radiological contamination.
43 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 12.2.3 Contaminated For patients known to be or suspected of being contaminated, TVA coordinates essential first aid and emergency medical care. Decontamination activities are accomplished as the medical status permits. Involved personnel are advised of the contamination hazard. Continued care and decontamination decisions are made on an individual basis by the responsible medical care provider and Rad Protection.
12.3 TRANSPORTATION OF INJURED PERSONNEL The decision to transport a patient offsite is the responsibility of the emergency medical care provider performing patient assessment, i.e., Emergency Medical Technician (EMT) or Registered Nurse. If conflicting decisions arise, the option which provides the patient with the optimal level of medical care is chosen.
When ambulance transportation is indicated, transport may be provided by either the site Fire Protection EMTs (using a TVA ambulance) or by an agreement ambulance service. The MERT Team Leader coordinates requests for offsite ambulance assistance through the SM. The SM performs initial requests and notifications for assistance.
TVA maintains arrangements for one or more agreement ambulance services for the CRN Site with trained personnel to transport patients, including those who may have been exposed to or contaminated with radioactive material. These services are designated in a CRN-EPIP and letters of agreement for response are maintained. (See Section 16.5.)
12.4 INTERAGENCY ASSISTANCE FROM REAC/TS TVA maintains arrangements with the Radiation Emergency Assistance Center/Training Site (REAC/TS) as the CRN Site receiving hospital. REAC/TS, which is in close proximity to the CRN Site, is a DOE-sponsored facility operated by Oak Ridge Associated Universities Medical and Health Sciences Division in cooperation with the Oak Ridge Methodist Medical Center in Oak Ridge, Tennessee. The University of Tennessee Medical Center in Knoxville, Tennessee serves as a back-up to REAC/TS. Specialized facilities and expert personnel are available at both medical facilities for definitive care for radiation emergency victims. Letters of Agreement for services are maintained. (See Section 16.5.)
44 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 13.0 TERMINATION AND RECOVERY 13.1 TERMINATION The SM/SED is responsible for the decision to terminate an event for which the onsite and offsite emergency response facilities have not been activated.
In the event of an incident requiring activation of onsite and offsite emergency centers, the SED coordinates the decision to terminate the event with the CECC Director after consultation with the plant technical and operations staffs. This decision is based upon a comprehensive review of plant status and system parameters. These considerations include, but are not limited to, the following:
- Stability of the reactor shutdown condition, i.e., successful progress toward a cold shutdown condition.
- Integrity of the reactor containment building.
- Operability of engineered safety systems and decontamination facilities.
- Availability and operability of a heat sink.
- Integrity of power supplies and electrical equipment.
- Operability and integrity of instrumentation including radiation monitoring equipment (also including portable equipment assigned during the emergency).
- Availability of trained personnel and support services.
- Control of radiological effluent releases.
State representatives are responsible for decisions to relax protective actions for the public. The CECC Director provides information to the appropriate State agencies to facilitate the decision.
The State has the authority and responsibility for offsite recovery efforts. TVA will provide assistance, as requested, through the recovery organization shown in Figure 13-1. (Figure 13-1 lists functions which must be addressed for recovery; the normal organizational titles may be different than what is represented here.)
The CECC Director, after consultation with the State, the SED, and discussion with the NRC (if appropriate), announces that the emergency has terminated and the recovery phase is to be initiated, if appropriate. TVA then develops procedures and plans to implement the most expeditious recovery sequence to return the plant to normal operation.

49 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 14.0 DRILLS AND EXERCISES 14.1 DRILLS Drills are conducted to develop and maintain key skills required for emergency response. These drills may be conducted individually or as part of an REP exercise.
The following drills are required:
14.1.1 Medical Emergency Drills A medical emergency drill involving a simulated contaminated/injured individual, with participation by a TVA or agreement ambulance and each agreement hospital (see Section 16.5) is conducted each calendar year for the CRN Site. Scenario development, drill activities, and evaluations will be jointly conducted and critiqued by EP and the site.
14.1.2 Radiological Monitoring Drills Environmental monitoring vehicle drills are conducted each calendar year for the CRN Site.
These drills include collection and analyses of sample media (i.e., water, air, grass, and/or soil as may be required by the scenario), direct radiation measurements, operation of vehicles, communication equipment, sampling equipment, and recordkeeping. The scenario is developed and the drills are conducted and critiqued by the site or EP.
14.1.3 Rad Protection Drills Rad Protection drills are conducted twice each calendar year for the CRN Site. These drills involve response to, and analysis of, simulated elevated airborne samples and direct radiation readings in the plant. The scenario is developed and the drills are conducted and critiqued by the site.
14.1.4 Radio Chemistry Drills Radiochemistry drills are conducted each calendar year at the CRN Site. These drills involve collecting and analyzing in-plant liquid and gaseous samples containing actual or simulated elevated levels, including use or simulated use of the post-emergency sampling system. The scenario is developed and the drills are conducted and critiqued by the site.
14.1.5 Radiological Dose Assessment Radiological dose assessment drills are conducted at least twice each calendar year to test the procedures, calculation techniques, computer codes, and environmental assessment abilities of the CECC staff and support groups. These scenarios are developed and the drills are conducted and critiqued by EP.
14.1.6 Fire Drills Fire drills will be conducted at the CRN Site in accordance with, and as required by, specific procedural requirements.
50 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 14.1.7 Communications Drills Communications drills are conducted at least once each calendar year at the CRN Site.
14.2 EXERCISES Exercises are scheduled and conducted such that:
- A biennial exercise will be conducted for the CRN Site to test the REP every 2 calendar years. State of Tennessee participation in other TVA Exercises within the State determines if there will be full or partial participation by the State during CRN Site Exercises.
- The CRN Site ensures that adequate emergency response capabilities are maintained during the interval between biennial exercises by conducting drills, including at least one drill involving a combination of some of the principal functional areas of the onsite emergency response capabilities. (The principal functional areas of emergency response include activities such as management and coordination of emergency response, emergency assessment, protective action decision making, and plant system repair and corrective actions. During these drills supervised instruction is permitted, and activation of all of the emergency response facilities is not necessary. Sites have the opportunity to consider emergency management strategies, operating staff have the opportunity to resolve problems (success paths) rather than have controllers intervene, and the drills can focus on onsite training objectives. Sites shall enable the states and local authorities to participate in such drills when requested.)
- An exercise is conducted for the CRN Site, with full participation by State and local authorities, every two years. (Where a State has more than one site it shall participate fully every two years at some site and partially participate at the other sites offsite exercises.)
- An exercise is conducted for the CRN Site such that the State may exercise emergency plans related to ingestion exposure pathway measures every eight years. (Where a State has more than one site, this participation should be rotated between sites.)
- Major elements of the emergency plans and organizations are tested within an eight-year period.
- The CRN Site initiates an exercise between 6:00 p.m. and 4:00 am at least once every eight years. The exact time of the exercise is unannounced.
14.3 SCENARIOS Drills and exercises are conducted in accordance with scenarios that have been properly planned, researched, and developed.
The drill and exercise scenarios include, but are not limited to, the following:
- The basic objectives of each drill or exercise.
51 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
- The date(s), time period, place(s), and participating organizations.
- The simulated events.
- A time schedule of real and simulated initiating events.
- A narrative summary describing the conduct of the exercises or drill, including simulated casualties, offsite fire department assistance, rescue of personnel, use of protective clothing, deployment of radiological monitoring teams, and public information activities.
Drill scenario development and implementation is the responsibility of the organization responsible for the specific drill.
Exercise scenario development and implementation is the responsibility of EP. Exercise scenario planning and development is coordinated with representatives of appropriate organizations and State agencies. Scenario specifics are not released by those representatives prior to the exercise.
Exercise scenarios will be developed to thoroughly test the REP on an eight year cycle. The exact time of an exercise is not released; however, a time span within which the exercise is to occur may be supplied to appropriate organizations and the news media so that the exercise is not confused with an actual emergency.
In the event a remedial exercise is required, a scenario is developed to demonstrate corrective measures have been taken regarding the described deficiencies.
14.4 CRITIQUES Representatives of Quality Assurance, INPO, NRC, DHS, State/local agencies and others may observe the exercise. Additional evaluators may be requested from other organizations as necessary. Evaluators are provided with sufficient material and a briefing prior to the exercise to become familiar with the Emergency Plan and exercise scenario.
At the conclusion of each exercise, a critique is conducted where the exercise and its participants are evaluated for effectiveness, procedural compliance and good practices. EP evaluates critique comments, develops a formal written report, coordinates corrective actions for deficiencies or items needing improvement, and follows up to ensure completion of corrective actions.
Drill critiques, critique reports, coordination of corrective action and follow-up to ensure completion is the responsibility of the organization administering the drill.
52 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ) 15.0 TRAINING TVA ensures that personnel with specific duties and responsibilities in the NP-REP receive instruction in the performance of these duties and responsibilities.

65 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Attachment 1 Justification for the Central Emergency Control Center Under 10 CFR Part 50, Appendix E, Section IV.E.8, TVA is required to provide a licensee near-site Emergency Operations Facility (EOF) from which effective direction can be given and effective control can be exercised during an emergency. The NRC provides guidance for design and location of the EOF in NUREG-0696, Functional Criteria for Emergency Response Facilities (NUREG-0696). Since the early 1980s, TVA has used a centralized concept for providing the EOF function for its nuclear sites. Consistent with this approach, the CRN Site Emergency Plan relies on the use of the Central Emergency Control Center (CECC) as the EOF for the CRN Site. The CECC serves as the EOF for the other TVA nuclear plants (Browns Ferry Nuclear Plant (BFN), Sequoyah Nuclear Plant (SQN), and Watts Bar Nuclear Plant (WBN)). The CECC is located in the TVA Chattanooga Office Complex (COC) in Chattanooga, Tennessee, approximately 78 air miles from the CRN Site. The CECC is further than 20 miles from the CRN Site Technical Support Center (TSC), as is the case for BFN, SQN, and WBN, but does not alter the functions of the EOF as described in NUREG-0696.
The use of the CECC as the EOF for the CRN Site allows TVA to continue to operate a standardized program for corporate management and response to radiological emergencies at TVA nuclear facilities. The effectiveness of CECC operations has been demonstrated during numerous drills and exercises. Communications systems, data links, and staffing have been incorporated and tested. Using the CECC for the CRN Site also allows TVA to apply its corporate emergency response structure and experience to the CRN Site Emergency Plan.
TVA has discussed this concept with the Tennessee Emergency Management Agency (TEMA).
TEMA is familiar with the CECC because the facility is used for responding to radiological emergencies at SQN and WBN. Through the letter referenced in SSAR, Section 13.3 of the CRN ESPA, TEMA confirms their support of the TVA emergency response program, included the use of the CECC in Chattanooga.
Access to the station by the NRC site team is accommodated. The CRN Site has a Local Recovery Center (LRC) which is a pre-designated facility dedicated for use by offsite TVA and NRC personnel that may be assigned to the CRN Site for recovery operations. In addition, the LRC may be used by the NRC during the event as an area near the site for assessment and assistance and has the capability to communicate offsite. Additional information regarding the LRC can be found in section 8.1.3 of this Plan and in A.4.8 in Appendix A.
The CECC includes space for State liaisons reporting to the CECC in Chattanooga.
The following discussion provides an evaluation of the CECC against the criteria provided in NUREG-0696.
66 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Evaluation Against NUREG-0696:
The CECC is designed to provide for the effective and timely performance of the following functions:
- Management of overall licensee emergency response.
- Coordination of radiological and environmental assessment.
The primary role of the CECC is to relieve the plant staff of the functions of keeping the federal, State, and county emergency response organizations informed, for directing dose assessment and field monitoring, for managing the informational needs of the media, interested industry groups, and elected officials, and for supporting the emergency assessment needs of the TSC staff. The NRC will have access to plant data through the CECC computer system and the Emergency Response Data System (ERDS). The NRC also has telephones on the Emergency Telecommunications System (ETS) in Chattanooga.
Equipment exists in the CECC for the acquisition, display, and evaluation of radiological, meteorological, and plant system data. Because a similar set of data currently used for BFN, SQN, and WBN are required for the CRN Site, the plant and effluent data would be provided on as timely a basis at the CECC as it would be at a near-site location.
Normal industrial security is already provided for the CECC and processes are already established to upgrade the security of the facility during an activation.
Location, Structure, and Habitability The CECC is located in the northeast corner of the sixth floor of Lookout Place in the TVA COC in Chattanooga, Tennessee. The CECC has proven to be an effective facility for implementation of the TVA nuclear station emergency plans. The CECC is used for existing TVA nuclear plants at the BFN, SQN, and WBN sites. The facility is more than ten miles from any of the TVA nuclear stations; therefore, there are no specific habitability criteria.
Staffing and Training Incorporation of CRN emergency response functions into the CECC will not adversely affect the ability of TVA to staff the CECC in a timely manner. The CECC is staffed with experienced personnel from the TVA COC and personnel from one or more TVA nuclear plants. The CECC staff has demonstrated their ability to staff the CECC within required time-frames following emergency declaration during previous staff augmentation drills. The CECC staff includes personnel to manage overall licensee emergency response, and coordinate radiological and environmental assessment.
Size The CECC size has proven to be adequate during drills and exercises for the existing TVA nuclear facilities. In addition, the NRC has workspace co-located with the decision makers, radiological assessment, and emergency assessment personnel.
67 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Radiological Monitoring The CECC is beyond 10 miles from any nuclear stations, and therefore does not require radiological monitoring equipment.
Communications The communications systems available in the CECC consist of:
- Central Office Trunks.
- Tie-lines.
- Digital Services.
- Privately-owned/maintained microwave systems.
- Privately-owned fiber-optic systems.
- NRC ETS phones.
- EP Radio System.
The emergency communications systems at the CECC are designed to provide a reliable, timely flow of information between the parties having an emergency response role. The single facility results in commonality of communications and interface with offsite officials and liaisons. The EP telephone system continues to be the primary means of communicating changes in event classification. This system operates on a combination of the TVA telecommunications network and leased circuits.
The offsite communications network is used to communicate with federal, State, and other supporting agencies. Access to these agencies is provided through several redundant, diverse routes. This diversity provides offsite routing through more than one type of facility. These facilities include, but are not limited to, commercial facilities such as central office trunks, tie-lines and digital services, plus privately owned and maintained microwave and fiber-optic systems. The offsite telecommunications network is designed to facilitate traffic in the most fail-safe manner to the emergency response organizations.
The Emergency Notification System (ENS) and Health Physics Network (HPN) (NRC FTS 2000 System) communication systems provide communications from each site TSC, Control Room, and the CECC to the NRC Headquarters and regional offices. These telephones are tested on a periodic basis consistent with the CRN Site Emergency Plan.
The EP radio system is a VHF mobile radio system which provides redundant radio coverage of the Plume Exposure Pathway (PEP) Emergency Planning Zone (EPZ) and provides radiological monitoring vehicles with mobile communications to other vehicle(s) and to the following locations: Radiological Control, TSC, Control Room at each TVA plant, and the CECC.
68 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Instrumentation, Data System Equipment, and Power Supplies Various plant parameters are available to the CECC staff via a connection through the TVA CECC computer network. Data available at the CECC provides a snapshot of data from each units integrated set of plant data. Plant data can be displayed at the CECC. These data are sufficient to perform emergency assessment and evaluate the potential environmental consequences of an emergency at the CRN Site. Detailed discussion on CRN Site plant-specific parameters are described in the Emergency Plan. The computers in the dose assessment area are capable of running the dose projection computer programs and accessing plant status data.
Hourly and 15-minute average meteorological data from the plant Environmental Data Station are available to the CECC, TSC, State, and LRC. The CECC computer system provides access to up to the most recent 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> of this data. A meteorologist in the CECC provides meteorological information to the CECC staff in support of offsite dose projections.
The CECC draws its primary power from commercial power. A loss of commercial power should not impact any of the voice or data communications equipment located in the CECC. Common TVA telecommunications infrastructure that supports CECC functions, including, but not limited to fiber optic transmission equipment, telephone switching equipment, and data network routers, is configured to operate from at least one and usually multiple backup power sources in the event of a loss of commercial power. These backup sources include generator, dc battery and uninterruptible power supply systems.
Technical Data and Data Systems As discussed in the previous section, a variety of plant parameters are provided over the TVA communications network to the CECC.
Reports Availability and Management Hard copies of key reference materials are maintained in the CECC. In addition, station design documentation, plant drawings, procedures, etc. are available via Local Area Network connection from the Business Support Library.
The following information is available for the CRN Site at the CECC:
- Plant technical specifications.
- Plant operating procedures.
- Emergency operating procedures.
- Final Safety Analysis Report.
- Up-to-date licensee, State, and local emergency response plans.
69 Revision 1
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Conclusion The CECC meets the functional and design criteria provided in NUREG-0696 for an EOF with the exception that it is located more than 20 miles from the CRN Site. This document describes the TVA approach to assuring that these functional and design criteria are met and maintained.
The consolidation of TVA corporate emergency response functions into a centralized facility provides a timely and effective response to a radiological emergency at the CRN Site.

Appendix A A.1 CLINCH RIVER NUCLEAR SITE AND EMERGENCY PLANNING ZONE DESCRIPTION A.1.1 FACILITY AND SITE CHARACTERISTICS A.1.1.1 Nuclear Power Facility The Clinch River Nuclear (CRN) Site is located on the Clinch River Property and is used as the location to construct and operate Small Modular Reactors (SMRs).
A.1.1.2 Site Location and Description The CRN Site Property covers an area of approximately 1,200 acres located adjacent to the Clinch River in Roane County, Tennessee. The CRN Site lies north of U.S. Interstate 40, approximately midway between the communities of Harriman and Farragut in the eastern portion of Tennessee.
Site Safety Analysis Report (SSAR) Chapter 2 provides additional information regarding the physical characteristics of the proposed site, including the preliminary site layout and potential hazards in the site vicinity. The Environmental Report provides detailed information addressing land use and other features of the proposed site and surrounding area.
The CRN Site Early Site Permit Application (ESPA) includes an Evacuation Time Estimate (ETE) Report, which provides the results of public evacuation analyses conducted in accordance with the guidance provided in NUREG/CR-7002, Criteria for Development of Evacuation Time Estimate Studies. The analyses reflected in the ETE Report did not identify physical characteristics unique to the proposed site that could pose a significant impediment to the development of emergency plans.
A.1.2 EMERGENCY PLANNING ZONES Section 50.47(c)(2) of 10 CFR 50 establishes two Emergency Planning Zones (EPZs) for consideration in nuclear power plant emergency planning. For the CRN Site, the plume exposure pathway (PEP) EPZ encompasses an area approximately 2 miles in radius surrounding the site. The ingestion exposure pathway EPZ encompasses an area that is yet to be determined. TVA intends to address this in the CRN Site Combined License Application (COLA).
In addition to the basic requirements for EPZ radius, development of the EPZs includes consideration of local emergency response needs and capabilities, including considerations of demography, topography, land characteristics, access routes, and jurisdictional boundaries. Of particular interest in the development of the CRN Site PEP EPZ is the overlapping emergency planning zone for the U.S. Department of Energy (DOE) Oak Ridge Reservation.
Figure A.1-1 provides a map of the PEP EPZ for the CRN Site.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan (2-Mile EPZ)
Appendix A A.2 EMERGENCY ACTION LEVELS Part 5B Section 4.2 indicates that recognition of the emergency class is primarily a judgment matter for plant personnel. The initiating conditions (ICs) used for recognizing and declaring the emergency class are based on specific measurable values or observable conditions defined as Emergency Action Levels (EALs). These can be combinations of specific instrument readings (including their rates of change), annunciator warnings, and time periods during which certain conditions exist, etc. CRN Site Emergency Plan Implementing Procedures (CRN-EPIPs) provide details regarding instrument readings and parameters required for determination of these EALs.
Tennessee Valley Authority (TVA) uses these EALs as thresholds for determining the emergency classifications. TVA develops the EALs based on industry guidance, engineering assessments, and insights provided by the reactor plant supplier.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate ABSTRACT The evacuation time estimate (ETE) detailed in this report is an analysis of the time required to evacuate the Plume Exposure Pathway Emergency Planning Zone (EPZ) for the Clinch River Nuclear (CRN) Site. The CRN Site is a proposed Small Modular Reactor (SMR) project on 1200 acres of land adjacent to the Clinch River arm of the Watts Bar Reservoir, south of the U.S. Department of Energy Oak Ridge Reservation (DOE/OR), within the City of Oak Ridge, in Roane County, Tennessee. The CRN Emergency Plan considers the unique plant design and margins to safety afforded by a SMR design, while maintaining emergency preparedness at appropriate levels to protect the health and safety of the public. For the proposed CRN Site, the EPZ is an area encompassing an approximate 2 mile radius around the proposed reactor center point location. NUREG/CR-7002, Criteria for Development of Evacuation Time Estimate Studies (NUREG/CR-7002), provides guidance for the development of ETEs. The guidance provided in NUREG/CR-7002 can be used to demonstrate compliance with the ETE analysis development required by the NRC in Section IV of Appendix E to Title 10 of the Code of Federal Regulation (CFR) Part 50 (10 CFR 50) and serves as a template for the development of this ETE study. Typically, the ETE is used to inform protective action decision-making and may also be used to assist offsite authorities in development of traffic management plans to support an evacuation. For purposes of the CRN Site Early Site Permit Application (ESPA), the ETE also serves to satisfy the requirements of 10 CFR 52.17(b)(1), which states that the site safety analysis report identify physical characteristics of the proposed site, such as egress limitations from the area surrounding the site, that could pose a significant impediment to the development of emergency plans and if physical impediments are identified, the application must identify measures that would, when implemented, mitigate or eliminate the significant impediment..
Consistent with guidance, this ETE has been developed to provide the time to evacuate 90 percent and 100 percent of the total population of the EPZ. The 90 percent ETE provides the evacuation times that would typically be used to support protective action recommendations and decision-making.

SUMMARY
This report describes the analyses undertaken to develop evacuation time estimates (ETE) for the Clinch River Nuclear (CRN) Site, and the associated results. The Clinch River Property consists of 1200 acres adjacent to the Clinch River arm of the Watts Bar Reservoir, south of the U.S. Department of Energy Oak Ridge Reservation (DOE/OR), within the City of Oak Ridge, in Roane County, Tennessee that is proposed to be used as the location to construct and operate a Small Modular Reactor (SMR) project.
Part 5 of the Early Site Permit Application (ESPA) being submitted for the CRN Site includes two (2) Emergency Plans (Part 5A and Part 5B) for review by the NRC. Part 5A will address a site boundary plume exposure pathway Emergency Planning Zone (EPZ) and Part 5B addresses a 2-Mile plume exposure pathway EPZ. The final EPZ size will be determined at the time the Combined License Application (COLA) is submitted. For purposes of the CRN Site ESPA, the ETE serves to satisfy the requirements of 10 CFR 52.17(b)(1), which states that the site safety analysis report identify physical characteristics of the proposed site, such as egress limitations from the area surrounding the site, that could pose a significant impediment to the development of emergency plans and if physical impediments are identified, the application must identify measures that would, when implemented, mitigate or eliminate the significant impediment. This ETE did not identify physical characteristics of the proposed site that could pose a significant impediment to the development of emergency plans.
In the event the site boundary EPZ is selected for the CRN Site, the Tennessee Valley Authority (TVA) has proposed an exemption from the requirements to perform an ETE and an update to this ETE will not be necessary.
The Clinch River Emergency Plan considers the unique plant design and margins to safety afforded by a SMR design, while maintaining emergency preparedness at appropriate levels to protect the health and safety of the public. The ETE are calculations of the time necessary to evacuate the Plume Exposure Pathway Emergency Planning Zone (EPZ), which is an area encompassing an approximate 2 mile radius around the proposed reactor center point location.
The exact size and configuration of the EPZ surrounding the CRN Site was developed in relation to local emergency response needs and capabilities as they are affected by such conditions as demography, topography, land characteristics, access routes and jurisdictional vii Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate boundaries. Of particular interest in the development of CRN Site plume exposure pathway EPZ is the overlapping emergency planning zone for the DOE/OR.
Section IV of Appendix E to Title 10 of the Code of Federal Regulation (CFR) Part 50 (10 CFR
- 50) requires that an analysis of the time required to evacuate be provided for various sectors and distances within the EPZ for transient and permanent residents. Consistent with Supplement 3, Guidance for Protective Action Strategies, of 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 (NUREG-0654), the Protective Action Recommendation for an EPZ encompassing an area of approximately 2 miles surrounding the CRN Site would be consistent throughout the EPZ. Therefore, the use of various sectors and distances within the EPZ is not appropriate for the CRN Site and this ETE only considers an evacuation of the entire EPZ reflecting the effects of seasonal variations, day-of-the-week, and adverse weather conditions. Based on the data obtained from the 2010 U.S. Census, projected to 2015, there are 856 permanent residents within the EPZ of the proposed CRN Site.
The ETE is primarily used to inform protective action decision-making and may also be used to assist in development of traffic management plans to support an evacuation, if deemed necessary by offsite response organizations (OROs). The ETE is used as an information tool, and therefore, no minimum evacuation time must be achieved. The guidance in NUREG-0654 Evaluation Criterion J.10, provides additional information regarding the use of ETE results. ETE are used by OROs when making offsite protective action decisions. This report was prepared based on guidance provided in NUREG/CR-7002, Criteria for Development of Evacuation Time Estimate Studies (NUREG/CR-7002).
This report provides details on the process used for the development of ETEs for two population segments, including:
- 1. Permanent residents and transient population.
- 2. Transit dependent permanent residents.
There are no school populations located within the EPZ.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate This report also provides details on the development of the evacuation demand considered in the ETE, preparation activities associated with development of the ETE, and the use of traffic simulation modeling. Other considerations included in this ETE analysis include:
- A shadow evacuation extending to 15 miles from the CRN Site assumes that 20% of the public outside the boundary of the EPZ to a distance of 15 miles from the CRN Site would spontaneously evacuate.
- Lack of existing emergency preparedness programs and evacuation plans, including:
- The absence of existing registration programs for people with disabilities and those with access and functional needs who do not reside in special facilities.
- The absence of existing evacuation routes.
- The absence of existing traffic control plans.
- Verification of the future commitment of resources, such as buses and ambulances.
- Consideration of the evacuation tail.
- Future ETE updates related to a Combined License Application.
This report includes a discussion of INTEGRATION, the traffic simulation model used in performance of the ETE and a summary of the key inputs, assumptions, outputs, and computational process associated with the simulation. The INTEGRATION software is listed in the U.S. Department of Transportations (DOT) Evacuation Management Operations (EMO)
Modeling Assessment: Transportation Modeling Inventory, developed to support selection of an appropriate model for use in evacuation analyses (Reference 1).
NUREG/CR-7002 establishes the need to include a 20 percent shadow evacuation in the analysis. A shadow evacuation is defined as an evacuation of people from areas outside an officially declared evacuation zone. The shadow population is considered in this analysis to account for any effect of people from the EPZ boundary to 15 miles impeding the evacuation of those under evacuation orders. According to the 2010 U.S. Census data, projected to the year 2015, there are approximately 186,500 permanent residents within 15 miles of the proposed CRN Site.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate
1.0 INTRODUCTION
The Clinch River Nuclear (CRN) Site is the location of a proposed Small Modular Reactor (SMR) nuclear power plant project adjacent to the Clinch River arm of the Watts Bar Reservoir, south of the U.S. Department of Energy Oak Ridge Reservation (DOE/OR), within the City of Oak Ridge, in Roane County, Tennessee. To account for the possibility of an emergency at the CRN Site, a hypothetical, unplanned release of radioactive materials is considered. This report describes the analyses undertaken to develop evacuation time estimates (ETE) for the populace located within the EPZ of the proposed nuclear power plant site, and the associated results.
The ETE analysis is an emergency planning tool that assesses, in an organized and systematic fashion, the feasibility of taking protective measures for the population in the area surrounding a nuclear power plant. For purposes of the CRN Site ESPA, the ETE serves to satisfy the requirements of 10 CFR 52.17(b)(1), which states that the site safety analysis report identify physical characteristics of the proposed site, such as egress limitations from the area surrounding the site, that could pose a significant impediment to the development of emergency plans and if physical impediments are identified, the application must identify measures that would, when implemented, mitigate or eliminate the significant impediment.
The ETE also provides a tool for offsite response organizations (OROs) to use in preplanning as well as protective action decision making should a radiological release requiring offsite protective action decisions occur. The ETE may also be used to assist in development of future traffic management plans to support an evacuation, as deemed appropriate by OROs. The ETE is used as a decision-making tool, and therefore, no minimum evacuation time must be achieved.
Section IV of Appendix E to Title 10 of the Code of Federal Regulation (CFR) Part 50 (10 CFR
- 50) requires that an analysis of the time required to evacuate be provided for various sectors and distances within the EPZ for transient and permanent residents. Consistent with Supplement 3, Guidance for Protective Action Strategies, of 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 (NUREG-0654), the Protective Action Recommendation for an EPZ encompassing an area of approximately 2 miles surrounding the CRN Site is expected to be consistent throughout the EPZ. Therefore, the use of various sectors and distances within the EPZ is not appropriate for the CRN Site and this ETE only 1 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate considers an evacuation of the entire EPZ reflecting the effects of seasonal variations, day-of-the-week, and adverse weather conditions. This report was prepared considering the ETE guidance provided in NUREG/CR-7002, Criteria for Development of Evacuation Time Estimate Studies (NUREG/CR-7002).
Roane County is located in southeastern Tennessee, encompasses 395 square miles, and has a population of approximately 54,000 residents distributed between five incorporated municipalities and its unincorporated areas. Kingston, the County seat, is located approximately 7 miles west-southwest of the proposed CRN Site. The Clinch River surrounds the CRN Site to the east, south and west. The county boundary is closest to the CRN Site approximately 3 miles to the east of the CRN Site.
The CRN Site is a proposed SMR nuclear power plant site. The CRN Emergency Plan considers the unique plant design and margins to safety afforded by a SMR design, while maintaining emergency preparedness at appropriate levels to protect the health and safety of the public. For the proposed CRN Site, the EPZ is an area encompassing an approximate 2 mile radius around the proposed reactor center point location. The EPZ encompasses sparsely populated areas and a portion of the DOE/OR. No major employment areas of the DOE/OR lie within the EPZ.
According to the U.S. Census 2010 data, projected to the year 2015, there are 856 permanent residents within the EPZ of the CRN Site. According to the 2010 U.S. Census data, projected to the year 2015, there are approximately 186,500 permanent residents within 15 miles of the proposed CRN Site. The EPZ is sparsely populated with no major commercial facilities. There are no schools, correctional facilities, licensed day care facilities, nursing home facilities or major retail facilities located in the EPZ.
Interstate 40 (I-40), located in the southeastern portion of the EPZ, is the primary east-west traffic route in the vicinity of the proposed CRN Site. I-40 crosses the EPZ boundary approximately 2 miles east and 2 miles south-southwest of the proposed CRN Site. Tennessee State Route 58 (Highway 58), located in the northwestern portion of the EPZ, is the primary north-south traffic route in the vicinity of the proposed CRN Site. Highway 58 crosses the EPZ boundary approximately 2 miles west and 2 miles north-northwest of the proposed CRN Site.
Numerous local roads are found throughout the EPZ. Figure 1.1 illustrates the area surrounding 2 Revision 0

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate The traffic simulation model INTEGRATION, used in performance of this ETE study, is a microscopic traffic assignment and simulation software that is well-suited for performance of ETEs for nuclear power plants. The INTEGRATION software calculates a number of Measures of Effectiveness (MOEs), which are addressed by NUREG/CR-7002 and it is listed in the U.S.
Department of Transportations (DOT) Evacuation Management Operations (EMO) Modeling Assessment: Transportation Modeling Inventory, (Reference 1) developed to support selection of an appropriate model for use in evacuation analyses.
INTEGRATION performs traffic simulations by tracking the movement of individual vehicles every 1/10 of a second. The INTEGRATION model computes a number of MOEs, including the network efficiency. This model has been validated against state-of-the-art delay estimation procedures using queuing theory and shockwave analysis and against standard traffic flow theory and has been utilized for the evaluation of real-life applications.
The key parameters gathered on the roadway segments include the length of roadway segment, the number of lanes on each segment, type of roadway intersection control (stop sign, yield sign, etc.), lane striping (left turn only, shared through and right turn, etc.), free-flow speed, base saturation flow rate, jam density, and speed-at-capacity. Additional details regarding the traffic simulation model utilized in this study are included in Section 4.2.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 1.1. Approach A meeting regarding the development of the ETE was conducted at the Tennessee Emergency Management Agency (TEMA) in Knoxville, Tennessee on January 9, 2014 and was attended by representatives of state and local emergency management and law enforcement agencies, local elected officials and representatives from various state and local government agencies and private-sector support organizations. The purpose of the meeting was to present the process used for developing the ETE for the proposed CRN Site and outline associated data and information needs that would be used as inputs in the ETE analysis. The meeting included a detailed discussion of the ETE process including the methods used to collect data (roadway survey, telephone survey and data collection forms).
Following the meeting, a detailed field survey of the EPZ roadway network was conducted to validate existing mapping and to obtain characteristics of the primary roadways in the EPZ.
Roadway characteristics obtained during the field survey include:
- Number of lanes
- Lane width
- Intersection configuration
- Lane channelization and striping
- Geometrics (curves and lengths)
- Posted and actual speeds
- Abutting land use
- Traffic control devices
- Unusual characteristics The detailed field survey was video archived for reference purposes during subsequent development of the INTEGRATION model network.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate A random telephone survey of households within the EPZ and surrounding area to 10 miles from the CRN Site was conducted to interview a statistically representative sample of residents.
The telephone survey resulted in interviews with 604 households and was designed to obtain information related to household demographics and the commuting habits of residents. This information was used to identify factors affecting the evacuee trip generation time (mobilization time) as well as other data to be used in the ETE analyses, including average household size, vehicles per household, vehicle occupancy and an estimate of the number of transit-dependent residents. The mobilization time is the major component of the total ETE when the EPZ population density is low and there is minimal traffic congestion, as is the case for the CRN Site.
The telephone survey provides a statistical confidence interval of plus or minus 4% at the 95%
level of confidence and is a sound, documented basis for the trip generation times needed to develop the calculated ETEs.
NUREG/CR-7002 defines the transient population as tourists, shoppers, employees, etc., who do not reside within the EPZ and other people temporarily visiting the EPZ (Reference 4).
Hotel, motel, and campground occupancy rates peak during the summer months and during special events in the area. A survey of the transient facilities was conducted to obtain information regarding the number of transients and vehicles expected at these locations. The survey was designed to obtain information related to the number of units at each facility, average yearly occupancy, average number of persons per occupied unit and average number of vehicles per occupied unit. The survey was used to estimate peak attendance at transient facilities. There are no hotels/motels and 1 campground/RV park within the EPZ. This facility is addressed in greater detail in Section 2.1.2.
One special facility, the Kingston Academy, currently exists within the EPZ. The Kingston Academy is a Psychiatric Residential Treatment Facility with living quarters and a capacity of 52 children between the ages of 5 and 17. The facility provides residential treatment and day treatment services. Special facilities are addressed in Section 2.3.
Data related to major employers (more than 50 total employees) provided in the CRN Site Early Site Permit Application (ESPA) Environmental Report (ER) was evaluated for use in development of this ETE. Major employers within the EPZ are addressed in Section 2.5.
8 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate There are no schools, correctional facilities, licensed day care facilities, nursing home facilities or major commercial or retail facilities located in the EPZ.
1.2. Assumptions According to NUREG/CR-7002, the planning basis for the ETE includes the assumption that a rapidly escalating emergency is underway, an evacuation is ordered promptly by emergency management officials and no early protective actions have been implemented (Reference 4).
A 2-mile EPZ is evaluated in this ETE analysis and is included among the regulatory exemptions requested in the CRN Site ESPA.
Development of potential exemptions for SMRs is based on various design and analysis considerations. Specifically, the SMR licensing basis events (or Design Basis Events, DBEs) are expected to have small and delayed source term releases that will result in predicted on-and off-site radiation doses significantly lower than those considered in the bases for existing nuclear power plant emergency planning requirements. For Beyond DBEs, analyses would need to conclude that the slow progression rate of postulated severe event scenarios provides sufficient time to initiate appropriate mitigating actions to protect the health and safety of the public.
The following table, Table 1.2, General Assumptions, provides assumptions that the NRC included in NUREG/CR-7002 and additional assumptions considered in development of the ETE, as appropriate for the CRN Site. The telephone survey discussed in Section 2.2 of this report provides information on vehicle usage. Those assumptions that are used exclusively within individual sections of this report are addressed and discussed in the applicable section.
Assumptions used, beyond those explicitly accepted by NRC in published guidance, are supported by available technical reports, telephone survey data, documented communications, and other sources. Scenario-specific assumptions are addressed in section 1.3 of this report.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Table 1.2 General Assumptions The ETE is measured from the time that the advisory to evacuate is issued to 1 the public within the EPZ (e.g., initial emergency alert system (EAS) broadcast.
Mobilization of the public begins after initial notification and includes all 2 preparation activities (time for commuters to leave work, time for commuters to travel home, time to prepare the house) 3 Evacuation time ends when the last vehicle has exited the EPZ.
Background traffic is on the roadway when initial notification occurs and stops 4 entering the EPZ upon establishment of Access Control Points at 90 minutes following the advisory to evacuate.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 1.3. Scenario Development As suggested in NUREG/CR-7002, the evacuation scenarios presented in Table 1.3, below, were modeled to reflect the effects of seasonal variations, day-of-the-week, adverse weather, special events, roadway impacts and the peak construction workforce at the proposed CRN site on the ETE (Reference 4). These scenarios were developed to identify combinations of variables and events to provide ETE under varying conditions to support protective action decisions and to provide a range of potential evacuation situations dependent on site-specific considerations.

- See Table 3.1 A description of each scenario used in the study is provided below.
Scenario # 1 - Summer Midweek Daytime (Normal Weather): This scenario represents a typical normal weather daytime period when permanent residents are generally dispersed within the EPZ performing daily activities and major work places are at typical daytime levels. This scenario includes assumptions that schools are closed and hotel and motel facilities are occupied at peak levels. The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. It is further assumed that 1/4 of the multiple 11 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate night transients remain in hotel rooms and/or campgrounds during the day and 3/4 are participating in recreational activities within the EPZ. It is further assumed that 1/2 of the 3/4 (3/8 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 2 - Summer Midweek Daytime (Adverse Weather): This scenario represents an adverse weather daytime period when permanent residents are generally dispersed within the EPZ performing daily activities and major work places are at typical daytime levels. This scenario includes assumptions that permanent residents will evacuate from their place of residence; schools are closed and hotel and motel facilities are occupied at peak levels. The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. Due to adverse weather, it is assumed that 1/2 of multiple night transients remain in hotel rooms and/or campgrounds and 1/2 are participating in recreational activities within the EPZ. Of the 1/2 that are participating in recreational activities within the EPZ, it is assumed that 1/2 (1/4 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 3 - Summer Weekend Daytime (Normal Weather): This scenario represents a typical normal weather weekend period when permanent residents are both at home and dispersed within the EPZ performing typical summer weekend activities. This scenario includes assumptions that permanent residents will evacuate from their place of residence; schools are closed and students are at home or with their families; work places are staffed at typical weekend levels and hotel and motel facilities are occupied at peak summer weekend levels.
The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. It is further assumed that 1/4 of the multiple night transients remain in hotel rooms and/or campgrounds during the day and 3/4 are participating in recreational activities within the EPZ. It is further assumed that 1/2 of the 3/4 (3/8 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 4 - Summer Midweek and Weekend Evening (Normal Weather): This scenario represents a typical normal weather midweek and weekend evening period when permanent residents are generally at home with fewer dispersed within the EPZ performing evening activities. This scenario includes assumptions that permanent residents will evacuate from their place of residence; schools are closed and students are at home; work places are staffed at 12 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate typical evening levels; hotel and motel facilities are occupied at peak summer levels and all transients are at their lodging facilities.
Scenario # 5 - Winter Midweek Daytime (Normal Weather): This scenario represents a typical normal weather weekday period during the winter when school is in session, permanent residents are generally dispersed within the EPZ performing daily activities and major work places are at typical daytime levels. This scenario includes assumptions that students will evacuate directly from the schools and hotel and motel facilities are occupied at 50% of the peak summertime levels. The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. It is further assumed that 1/4 of the multiple night transients remain in hotel rooms and/or campgrounds during the day and 3/4 are participating in recreational activities within the EPZ. It is further assumed that 1/2 of the 3/4 (3/8 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 6 - Winter Midweek Daytime (Adverse Weather): This scenario represents an adverse weather weekday period during the winter when school is in session, permanent residents are generally dispersed within the EPZ performing daily activities and major work places are at typical daytime levels. This scenario includes assumptions that students will evacuate directly from the schools; work places are fully staffed at typical daytime levels and hotel and motel facilities are occupied at average levels. The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. Due to adverse weather, it is assumed that 1/2 of multiple night transients remain in hotel rooms and/or campgrounds and 1/2 are participating in recreational activities within the EPZ. Of the 1/2 that are participating in recreational activities within the EPZ, it is assumed that 1/2 (1/4 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 7 - Winter Weekend Daytime (Normal Weather): This scenario reflects a typical normal weather winter weekend period when permanent residents are both at home and dispersed within the EPZ. This scenario includes assumptions that schools are closed and students are at home; work places are staffed at typical weekend levels; and hotel and motel facilities are occupied at average weekend levels. The scenario assumes that 1/4 of the transients are in the EPZ for a single night and 3/4 are staying multiple nights. It is further assumed that 1/4 of the multiple night transients remain in hotel rooms and/or campgrounds 13 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate during the day and 3/4 are participating in recreational activities within the EPZ. It is further assumed that 1/2 of the 3/4 (3/8 of total transient population within the EPZ) will return to their lodging facilities to retrieve belongings.
Scenario # 8 - Winter Midweek and Weekend Evening (Normal Weather): This scenario reflects a typical normal weather midweek and weekend evening period when permanent residents are home and the work force is at a nighttime level. This scenario includes assumptions that schools are closed and students are at home; work places are staffed at typical nighttime levels; and hotel and motel facilities are occupied at average winter levels and all transients are at their lodging facilities.
Scenario # 9 - Roadway Impact Summer Midweek Daytime (Normal Weather): The intent of this scenario is to represent a variety of conditions that may impact a roadway segment such as construction, flooding, vehicle accidents, etc. The roadway impact scenario assumes that during a summer midweek normal weather daytime scenario, one section of an eastbound lane of I-40 is shut down near the EPZ boundary, resulting in a reduction in capacity. All assumptions included in Scenario #1 are included in this scenario. This analysis is conducted to understand the potential impact of such an event and to support the development of a traffic control plan by identifying areas where OROs may want to consider additional emergency planning such as the pre-positioning of response vehicles (e.g., tow trucks). The ETE for this scenario is not typically used in protective action recommendations or decision-making.
Figure 1.2 illustrates the location of the roadway impact scenario.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Scenario # 10 - Peak Construction Midweek Daytime (Normal): This scenario represents a typical normal weather midweek daytime period when the peak number of construction workers are on-site and permanent residents are generally dispersed within the EPZ performing daily activities and major work places are at typical daytime levels. Up to 2,700 construction workers would be required during the peak phase of construction activities for a Small Modular Reactor plant at the Site. Peak plant staff is expected to be 500 employees. Construction workers and plant staff are expected to commute because there are no provisions for housing at the Site. A site plan detailing road access to the Site has not been finalized. Therefore, it was assumed that driveway access to and from the Site would be along Bear Creek Road. This scenario includes assumptions that schools are closed and hotel and motel facilities are occupied at peak levels. Assumptions related to the transient population are identical to Scenario #1. The existing roadway system was used for this scenario and no roadway improvements were considered. According to the census data in the area, the overall permanent population increasing rate from 2015 to 2024 is estimated to be 2.64%. Permanent resident and shadow populations were extrapolated to 2024 for this scenario.
1.3.1. Staged and Keyhole Evacuation NUREG/CR-7002 addresses the use of staged and traditional keyhole evacuations when making protective action decisions. Evacuation research has shown that implementation of a staged evacuation can be more beneficial to the public health and safety than the traditional keyhole evacuation (Reference 2). However, NUREG/CR-7002 was developed considering an EPZ size of an approximately 10-mile radius, where the benefits of a staged and traditional keyhole evacuations may be realized, given site-specific characteristics.
In a typical (NUREG/CR-7002) staged evacuation, evacuation times for the 0-2 mile and the 2-5 mile portions of a 10-mile EPZ are calculated separately to support a staged evacuation protective action decision (i.e., evacuation of the 0-2 mile zone, followed by subsequent evacuation of the 2-5 mile zone). Because this ETE analysis for the CRN Site considers an EPZ encompassing an approximate 2 mile radius around the proposed reactor center point location, staged and traditional keyhole evacuations are not appropriate for the CRN Site and have not been considered in this analysis. Instead, this analysis considers an evacuation of the entire EPZ for each evacuation scenario. Based on the data obtained from the 2010 U.S.
16 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Census, projected to 2015, there are 856 permanent residents within the EPZ of the proposed CRN site.
1.4. Emergency Response Planning Areas As described in NUREG/CR-7002, conduct of the ETE typically requires consideration of discreet planning areas within the EPZ, referred to as Emergency Response Planning Areas (ERPAs) (Reference 4). ERPAs are defined as local areas within the EPZ for which emergency response information is provided. The establishment of ERPAs within an EPZ enables protective action recommendations and decisions to be made at the ERPA level. With a 2-mile EPZ, during an emergency at the CRN Site, protective actions will be implemented consistently throughout the EPZ. For this reason, development of ERPA within the EPZ are not necessary and ERPA are not considered in this analysis. Based on the characteristics of the EPZ for the proposed CRN Site, ETEs were developed for the complete evacuation of the entire EPZ for each evacuation scenario considered.
The permanent resident and transient populations for the EPZ are discussed in Section 2 of this report.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 2.0 DEMAND ESTIMATION This section of the ETE report details the process for developing an estimate of the number of people to be evacuated from the EPZ. The demand estimation includes permanent residents, transients, individuals with special needs, and any other members of the public in the EPZ at the time an evacuation is ordered. The potential exists for counting individuals in more than one of these groups (i.e., EPZ resident may also be counted as an employee or transient). To avoid double-counting permanent residents, and as a result, overestimating the number of evacuating vehicles, the percent of permanent residents of the EPZ assumed to be at parks, shopping, places of employment or other locations within the EPZ is identified in appropriate sections of this ETE report. Demographic data obtained from the U.S. Census 2010 (projected to 2015), a random telephone survey of permanent residents in the EPZ and surrounding area, and assumptions detailed throughout this ETE report, have been used to estimate the number of people and vehicles considered in the ETE. Demand estimates for the following population groups have been considered separately and account for all of the public in the EPZ:
- Permanent Residents and Transient Population (with access to a vehicle during an evacuation).
- Transit Dependent Permanent Residents (without access to a vehicle or dependent on help from outside the home to evacuate).
- Special Facility Residents (Residents of or those confined to nursing homes, jails, assisted living centers, hospitals, etc.).
- Schools (Public and private educational facilities).
Estimates of the population and number of evacuating vehicles for each of these population groups have been developed separately and are described in the following sections.
2.1. Permanent Residents and Transient Population The permanent resident population has been estimated using Census block data obtained from the U.S. Census 2010 and is projected to 2015 for this analysis. To determine the permanent resident population, the block data was loaded directly into geographic information systems (GIS) software and the permanent resident population and number of households were 18 Revision 0

The EPZ permanent residents, by sector, is presented in Table 2.1. Table 2.1 includes residents in the 2 to EPZ Boundary to reflect those areas where the EPZ extends irregularly beyond a 2-mile radius. The EPZ permanent resident population, the number of households and the number of evacuating vehicles are presented in Table 2.2.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate The transient population is defined as those people temporarily visiting the area and includes tourists, shoppers and employees who work in the EPZ but do not reside in the EPZ.
Estimates of the size of the transient population were obtained and used to determine the associated number of evacuating vehicles. A listing of transient population facilities and special event data was obtained through a combination of internet research and questionnaires, and interviews with facility representatives. Data gathering surveys focused on acquiring the number of hotel/motel rooms and campsites at each transient facility within the EPZ; the typical number of guests in each hotel/motel room and campsite and the average number of vehicles per hotel/motel room/campsite. The number of transients at these facilities was estimated based on the information obtained.
The average EPZ household size of 2.2 persons per household was applied to the transient population to determine the number of transient units. Transients are assumed to evacuate at the same value as the EPZ population, 1.7 people per evacuating vehicle. Section 2.1.2 provides estimates of the peak transient population presented by facility type. The peak transient population is illustrated by sector in Figure 2.2.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 2.1.1. Permanent Residents with Vehicles The estimated number of evacuating vehicles per household (1.3) was adapted from the results of the random telephone survey of the households in the EPZ and surrounding area. These data, along with the estimated number of households in the EPZ were used to calculate the number of evacuating vehicles provided in Table 2.1 in the following manner:
EV = Evacuating Vehicles HH = Household Evacuating Vehicles = HH x EV HH As an example, Evacuating Vehicles:
= 389 x 1.3 HH
= 506 Evacuating Vehicles The actual need for permanent resident vehicles is thereby less than the given estimate.
However, the estimate of permanent resident vehicles is not reduced to account for schoolchildren outside of the EPZ at the time of an evacuation.
2.1.2. Transient Population Transient population groups are defined as those people who are not permanent residents and who enter the EPZ for a specific purpose (camping, recreation, etc.). Transients may spend less than one day in the EPZ or they may stay overnight or longer at camping facilities, hotels and motels. The only transient facility in the EPZ identified during development of the ETE is a campground located approximately one mile south of the CRN Site. Based on information obtained from the facilitys website, the facility has approximately 90 campsites. This facility is discussed in greater detail below.
Hotels and Motels There are no hotels or motels that have been identified within the EPZ.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Campgrounds There is 1 campground/RV park within the EPZ.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate campsite (equivalent to the EPZ persons per household), the peak attendance at the campground is estimated as 197 people evacuating in 116 vehicles (assuming 1.7 persons per evacuating vehicle). Based on the small permanent resident population within the EPZ and the relatively small transient population associated with this single facility, the impact of double counting any permanent EPZ residents that may be at this facility is minimal. Therefore, no permanent EPZ residents are assumed to be at this facility. A summary of the transient facility population is included in Table 2.5.

Schoolchildren would typically be included as a segment of the transit dependent permanent resident population. However, as described in Section 2.4, there are no schools located within the EPZ. The estimated number of transit-dependent permanent residents was adapted from the results of the random telephone survey of the households in the EPZ and surrounding area.
In addition to households that do not own a vehicle, consideration was also given to those households with 1 or 2 vehicles identified by the telephone survey. Calculations related to households with 0, 1 or 2 vehicles available during an evacuation are described below.
0-Vehicle Households The telephone survey indicated that 2% of the households in the EPZ do not own a vehicle. As indicated in Table 2.2, there are an estimated 389 households located in the EPZ; resulting in approximately 8 households without access to a vehicle during an evacuation. The telephone survey also indicates that of those households with no vehicles available for evacuation, the average household size is 1.2 people per household. This translates to approximately 10 29 Revision 0

1-Vehicle Households The results of the telephone survey indicate that approximately 21.8% of the households in the EPZ have 1 vehicle. The telephone survey also indicated that 42% of households in the EPZ have a commuter and 26.4% of commuters would not return home prior to evacuating. The telephone survey also indicates that of those households with 1 vehicle available for evacuation, the average household size is 1.48 people per household. This results in approximately 10 households (389 X 0.218 x 0.42 x 0.264) or 5 people (10 x (1.48 - 1)) (considering the commuter is away with the vehicle) in 1-vehicle households would not have access to a vehicle during an evacuation.
2-Vehicle Households The results of the telephone survey indicate that approximately 43.8% of the households in the EPZ have 2 vehicles. The telephone survey also indicated that 42% of households in the EPZ have a commuter and 26.4% of commuters would not return home prior to evacuating. The telephone survey also indicates that of those households with 2 vehicles available for evacuation, the average household size is 2.18 people per household. This results in approximately 2 households (389 X 0.438 x (0.42 x 0.264)2) or 1 person (2 x (2.18 - 2))
(considering both commuters are away with both vehicles) in 2-vehicle households would not have access to a vehicle during an evacuation.
3 or More-Vehicle Households The telephone survey indicates that of those households with 3 or more vehicles available for evacuation, the average household size is 2.58 people per household. Because the average household size is less than the number of vehicles available to the household, it is assumed that households with 3 or more vehicles will always have a vehicle available at home for evacuation during an emergency.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Transit-Dependent Ridesharing As discussed in NUREG/CR-7002, it is recognized that a portion of the transit-dependent population will rideshare during an evacuation, leaving the area with friends, neighbors, or relatives, and it is acceptable to assume that up to 50 percent of residents without vehicles will rideshare (Reference 4). This value is based on results of a national telephone survey conducted of EPZ residents (Reference 2) which indicate more than 50 percent of residents would offer a ride to individuals waiting for transportation. Empirical data obtained from the widely studied Mississauga, Canada evacuation in 1979 (Reference 3) also supports a value of 50 percent. Roane County emergency management officials agreed that a value of 50 percent was acceptable for this study. As a result, it is estimated that 9 people in 0-, 1-, and 2-vehicle households will require transit assistance during an evacuation. The number of transit-dependent permanent residents in 0, 1, and 2-vehicle households in the EPZ is summarized in Table 2.6.
Homebound Special Needs Population A subset of transit dependent residents includes people with disabilities and those with access and functional needs that live independent of a special facility. During development of the ETE, attempts were made to obtain data from Roane County to determine the demand for transit resources to accommodate homebound special needs individuals. Information on households with residents dependent on specialized transportation, such as wheelchair vans or ambulances, could not be provided by Roane County. However, as described in NUREG/CR-7002, a recent telephone survey of residents living within EPZs in the U.S. found that 6% of respondents said they, or someone in their household, would need assistance to evacuate (Reference 4). NUREG/CR-7002 cited NUREG/CR-6953, Vol. II, SAND2007-4195P, Review of NUREG-0654, Supplement 3, Criteria for Protective Action Recommendations for Severe Accidents - Focus Groups and Telephone Survey, October 2008 (Reference 2), as the source of this information. Because of the absence of information related to households with residents dependent on specialized transportation, it is assumed that 85% of special needs individuals requiring transportation are ambulatory and capable of being transported via buses. It is further assumed that 10% of special needs individuals requiring transportation are wheelchair bound, not capable of walking short distances, and require transportation via wheelchair bus and 5% of special needs individuals requiring transportation are bedridden and require transportation via 31 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate ambulance. It is further assumed that there are no more than 1 special needs individuals per household.
Based on the total permanent resident population of 856 within the EPZ of the CRN Site, it is estimated that approximately 24 households in the EPZ would house a special needs individual requiring assistance during an evacuation. Based on the assumptions above that 85% of special needs individuals are ambulatory (21 persons) 10% are wheelchair bound (3 persons) and 5% are bedridden (2 persons) it is estimated that a total of 26 homebound special needs individuals will be evacuated. Because the locations of these individuals is unknown, it is estimated that 2 buses will service those individuals that are ambulatory. Additionally, 1 wheelchair bus will service the wheelchair bound individuals and 2 ambulances will service the bedridden individuals. The number of transit-dependent permanent residents in a special needs situation is summarized in Table 2.6.
2.3. Special Facility Residents Special facility residents are those who reside in special facilities and are dependent upon facility personnel or emergency medical services vehicles for transportation in an emergency.
This includes, but is not limited to, institutions such as hospitals, nursing homes, and correctional facilities. The presence of special facilities was researched during development of the ETE and it was determined that one facility, the Kingston Academy, currently exists within the EPZ.
The Kingston Academy is a Psychiatric Residential Treatment Facility with living quarters and a capacity of 52 children between the ages of 5 and 17. The facility provides residential treatment and day treatment services. For this ETE, it is assumed the facility is at 90% capacity when an evacuation is ordered and the facility is ready to evacuate 75 minutes (60 minutes to prepare +
15 minutes to load vehicles) after the order to evacuate is issued. This results in an evacuation of approximately 47 residents from this facility. Because of the type of facility, it is assumed that all residents of the Kingston Academy are ambulatory. The number of transit-dependent residents in special facilities is summarized in Table 2.6.

Schools The presence of schools was researched during development of the ETE and it was determined that no schools currently exist within the EPZ.
2.5. Other Demand Estimate Considerations Demand estimates have also been considered for EPZ employees; a peak transients population during a special event just outside the EPZ; a shadow evacuation of 20% of the permanent resident population outside of the EPZ extending to 15 miles from the proposed CRN Site; and for background and pass through traffic within the EPZ. A summary of the shadow evacuation population and vehicles are included in Tables 2.8 and 2.9.
33 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Employees In addition to the demand estimates for permanent resident and transient populations described above, demand estimates were also considered for people who work in the EPZ. There are two categories of people who work in the EPZ:
- 1. Those who live and work in the EPZ.
Those of the first category are already counted as part of the permanent resident population and previously accounted for in the demand estimate. In order to estimate the number of people who live outside the EPZ and commute to jobs within the EPZ, the presence of major employers in the vicinity of the CRN Site (50 or more employees) was researched during development of the ESPA ER and was evaluated for use in development of this ETE report. It was determined that two major employers exist within the EPZ. Information on the major employers is included in Table 2.7.
Table 2.7 Major Employers in the EPZ Distance Facility Employees Evacuating Direction Location Employees (miles) Name per Vehicle Vehicles*
Kingston 0.95 SW Kingston 150 1 36 Academy 0.75 WSW Duratek Kingston 300 1 71 Total 107
- Assume 90% of employees are at work when the order to evacuate is issued and 26.4% of employees evacuate directly from their place of employment (based on the results of the telephone survey). The remainder of the employees return home and are included in the permanent resident EPZ population.
2.5.1. Special Events Special events within an EPZ and can attract large numbers of transients for short periods of time. Special events could include Fourth of July celebrations, holiday parades, professional and amateur sporting events, or any number of activities that bring large populations into the 34 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate EPZ. These events frequently define the peak tourist population that is to be included in the ETE study (Reference 5).
Kingston, Tennessee hosts the Smokin the Water 4th of July Celebration (http://www.kingstonparks.com/Fourth%20of%20July%20-%20Smokin%20the%20Water.htm) each year with activities centered on the Kingston waterfront at Watts Bar Lake, approximately 10 miles west of the CRN Site and 8 miles outside the EPZ. The event is typically a one-day event, and features a floating parade, drag boat and raft races, children's activities, a classic car show, commercial and craft vendors and fireworks. It is assumed that this event will result in peak tourist populations at transient facilities within the EPZ. This peak tourist population is considered in the Scenario #4 described in Section 1.3. Based on the small permanent resident population in the EPZ, it is assumed that all permanent residents remain in the EPZ during this event and no reduction in permanent resident population is considered.
2.5.2. Shadow Evacuation A shadow evacuation is defined as an evacuation of people from areas outside an officially declared evacuation zone. The shadow population is considered in this analysis because the additional traffic generated has the potential to impede the evacuation of those in the EPZ under evacuation orders. Shadow evacuations were considered in developing the demand estimation because of the additional traffic typically generated during an evacuation and its potential to affect the ETE. Consistent with NRC guidance, a shadow evacuation of 20% of the permanent resident population was assumed to occur in areas outside of the EPZ for all cases extending to 15 miles from the CRN Site. Shadow population was determined based on U.S. Census 2010 data, projected to 2015. As noted in Table 1.2, the area outside the EPZ is assumed to have a shadow evacuation of 20% of the permanent resident population.
According to the Census data, projected to 2015, there are 186,500 permanent residents living within 15 miles of the CRN Site. It is assumed that the trip generation times for the shadow evacuation onto the roadway network is consistent with the trip generation times for the permanent resident population within the EPZ.
Figure 2.4 illustrates the permanent resident population by sector, at 1-mile increments from the EPZ boundary to 15 miles from the CRN Site.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Figure 2.4 Population Estimates for the Shadow Evacuation Area 2.5.3. Background and Pass-Through Traffic Background and pass-through traffic will exist within the EPZ at the time an order to evacuate is issued. Background traffic is that traffic on the roadways when the initial notification to evacuate occurs and consists of both permanent residents and transients. Pass-through traffic includes 36 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate vehicles that enter the EPZ roadway network and exit the EPZ prior to the establishment of Access Control Points (ACPs).
QUEENSOD, software developed by Virginia Tech Transportation Institute (VTTI), was used to estimate the background and pass-through traffic. Because origin-destination (O-D) demand data is not readily available and difficult to obtain unless a large scale O-D survey is conducted, a method is needed to estimate demand by readily available data, such as traffic count data.
QUEENSOD is a model for estimating origin-destination traffic demands based on observed link traffic flows, observed link turning movement counts, link travel times and, potentially, additional information on drivers route choices. QUEENSOD iteratively minimizes errors between observed link volumes to estimated link flow using Least Relative Error model and generates an O-D matrix.
Pass-through traffic, used as input data in the ETE simulations, was determined based on the latest published traffic statistics, provided by the Tennessee Department of Transportation (http://www.tdot.state.tn.us/traffichistory). Annual Average Daily Traffic (AADT) on road sections of the State Highways and Local Federal-Aid roads are included on each of the major roadways within the EPZ. The count station, or specific location on a roadway where traffic count surveys are conducted, and the roadway network in the vicinity of the CRN Site are shown in Figure 2.3.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate To validate the results of QUEENSOD, the output of the QUEENSOD, the O-D matrix, is used in INTEGRATION as input demand file. The simulation is then run and the link traffic counts are recorded and calibrated against the observed traffic count data. The figure below shows the relationship between the observed link volumes versus the simulation volume. As evidenced by the following figure, the results from QUEENSOD accurately replicate the known network demands. The coefficient of determination R2 (a statistical measure of how close the data are to the fitted regression line) is very close to 1.
Figure 2.6 Network Demand Validation The background and pass-through traffic volume is estimated, and the calibration verified, for each scenario with consideration given to the effects of seasonal variations, day-of-the-week, adverse weather and other factors.
It is assumed that ACPs would be staffed within approximately 90 minutes of the advisory to evacuate. Activation of ACPs prior to 90 minutes could delay commuters returning from areas outside of the EPZ. Therefore, for purposes of this analysis, it is assumed that ACPs will be 39 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate established at 90 minutes following the advisory to evacuate. It is also assumed that no vehicles will enter the EPZ after ACPs have been established. The establishment of ACPs at 90 minutes following the advisory to evacuate has been confirmed with OROs.
From the time an evacuation order is issued until 90 minutes after the order is issued, background traffic begins to diminish as evacuating traffic begins to exit the EPZ and the establishment of ACPs prevent inbound traffic from entering the EPZ. The evacuating traffic begins to increase at the rate of the time distributions related to the trip generation times (see section 4.1). The background and pass-through traffic stops entering the EPZ 90 minutes after the order to evacuate is issued.
2.6. Summary of Demand Estimation A total of 10 Scenarios were evaluated for an evacuation of the full EPZ. As previously described, the use of various sectors and distances within the EPZ is not appropriate for the CRN Site and this ETE only considers an evacuation of the entire EPZ reflecting the effects of seasonal variations, day-of-the-week, and adverse weather conditions resulting in a total of 10 unique evacuation cases. Each scenario results in a specific population to be evacuated. Table 2.8 provides a summary of the total populations used in the analysis for each scenario for an evacuation of the EPZ. Table 2.9 provides a summary of the total number of vehicles, by population group (permanent residents, transients, transit dependent residents, shadow population, background and pass-through), for each scenario for an evacuation of the EPZ and represents the input values used in the traffic simulation modeling.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 3.0 ROADWAY CAPACITY In conjunction with the development of the traffic network in the vicinity of the CRN Site, an estimate of roadway capacity is required. Roadway capacity is defined as the maximum rate at which vehicles can be expected to traverse a section of roadway during a given time period under prevailing roadway, traffic, weather, and control conditions. The capacity analysis in this study has been performed using the application of processes and equations established in the U.S. Department of Transportations Highway Capacity Manual (HCM) (Reference 6). The (LOS), as defined in the HCM, provides a quality measure of the traffic operational conditions of a roadway and is designated as A for free flow operating conditions through F for congested operating conditions.
The roadway network in the vicinity of the CRN Site consists of the following three primary categories of roads:
- 1. Two-lane Local Roads - Various local and residential streets are located within the city limits of Oak Ridge and Roane County.
- 2. State Roads (Highway 58) - The portion of Highway 58 traversing the EPZ begins at an interchange with I-40 west-southwest of the CRN Site, then heads northeast, crossing the EPZ boundary 2 miles west of the CRN Site. Highway 58 continues northeast, before turning north and exiting the EPZ, 2 miles north-northwest of the CRN Site.
- 3. Freeways (I-40) - I-40 is the primary east-west route through the EPZ and crosses the EPZ boundary 2 miles east and 2 miles south-southwest of the CRN Site.
The following sections discuss the methods used in this study to determine roadway capacity.
3.1. Roadway Characteristics Roadway characteristics were obtained from an ArcGIS network file, which is imbedded in the raw calibrated data obtained from the data provider. Roadway characteristics, such as number of lanes, lengths, and free flow speed were extracted from the network file and exported to simulation input files. Table 3.1 provides the definition of free flow speed based on functional class. There are six functional classes in the CRN Site area according to the definition of the roadway databases. Speed at capacity and jam density were then designed according to 43 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate suggestions from the HCM. Based on field surveys, such roadway characteristics were further adjusted and calibrated to reflect real situations. The roadways included in the ETE analysis are primarily functional class 2 to 5 in the vicinity of the CRN Site.

A link is defined as a segment of roadway between two nodes. A node is an identification designator used to connect links in a roadway network model or to apply input data onto the network. Nodes are at intersections, ramps, etc., and contain characteristics such as traffic control and may be used as input points to assign loading of vehicles. Links are identified using blue text and nodes are identified as boxes with accompanying black text identifiers in Figures 3.1 through 3.4.
Characteristics for the roadways in the roadway network, including nodes, links and loading input information are included in Appendix A.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 3.2. Capacity Analysis Although the majority of the parameters for the road network that are input variables for the simulation are imported from the GIS database providers, local adjustments were conducted to ensure the accuracy of variables. The principles used for adjusting the variables are based on the HCM and the Green Book (A Policy on Geometric Design of Highways and Streets from AASHTO) (Reference 7).
The capacity of a road, according to the HCM, is the maximum sustainable hourly flow rate at which vehicles can reasonably traverse a point during a given time period under prevailing roadway, traffic, and control conditions (Reference 6).
According to the HCM, the factors affecting capacity of a roadway include design speed, number of lanes, the width of the lanes, shoulder, geometrical features (horizontal and vertical curves), traffic compositions as well as some other environment factors, such as weather, visual obstruction of the roadway, etc (Reference 6). These factors need to be incorporated into the simulation environment such that the simulation will be able to reflect the real traffic status, especially during the process of evacuation when congestion is possible in the network.
The capacity of the roadway is defined according to the recommendations by the HCM. The roads in the vicinity of the CRN Site are divided into the six functional classes based on the features of the roads, including hierarchy in the network, traffic load, serving environment, design speed, etc. The capacity of each class is defined in Table 3.1. The capacity in Table 3.1 is the description of network under perfect traffic conditions. As described in Section 3.4, a reduction in capacity is considered for ETE scenarios 2 and 6, considering adverse weather conditions.
3.3. Intersections Control Similar to the roadway capacity, intersection capacity is determined by multiple factors such as roadway geometrics, lane width, and number of lanes, etc. In addition, because intersections are the meeting point of two or more roads and they are usually controlled by traffic lights or other traffic control methodologies (stop signs or yield signs), the capacity at intersections will also be affected by the cycle length of the traffic signal, green time, turning movements, the 49 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate conflicting traffic, and other factors. It is important to reflect the prevailing intersection control treatments in the simulation such that the real traffic conditions should be replicated.
The underlying rules and parameters adopted by INTEGRATION at intersections, such as left and right turn gap acceptance, acceleration rate, discharge headway, and driver behavior during yellow light et al., are constructed in accordance with the recommendations from the HCM and are calibrated in-field.
The intersection traffic control data in the CRN Site area were obtained from two major sources.
Traffic signal timing data, including cycle length and phases, were requested from local town or county traffic agencies. Field survey data provided supplemental information for certain intersections. Stop signs and yield signs controlled intersections are identified from Google street view images. Data are then coded into an input file for INTEGRATION and are calibrated to field observations in terms of travel speeds and counts. Because the data obtained from local transportation agency is incomplete, estimation of cycle lengths and split of the signal is conducted based on the locations of the intersections where the signal data are not available.
The rules for estimation are based on geographic locations and road class resemblance. A similar traffic signal timing plan at an adjacent intersection of the same road class in the area was adopted for intersections where the data are not available. Because it is not uncommon for traffic control personnel to direct traffic and override the existing traffic signal plans resulting in improvement in the capacity of the intersections during an evacuation, the simulation optimizes the cycle lengths and offset times at a frequency of 5 minutes.
Characteristics for the intersections, including control summaries and signal files, are included in Appendix A.
3.4. Adverse Weather According to the HCM, during adverse weather the capacity and free flow speed of the roadway will be impaired (Reference 6). Table 3.2 illustrates the capacity drop and free flow speed reduction on freeways suggested by research conducted during previous studies.

Heavy Snow/Ice 20% - 28% 20% - 35%
The reduction in capacity and speed is calculated based on several factors including pavement condition, terrain, roadway functional class, and other factors. In accordance with the guidance presented in NUREG/CR-7002, the following roadway capacity and speed reduction factors were adopted for use in Scenarios 2 and 6, respectively (Reference 4). The values in Table 3.3 for heavy rain and snow are derived from Chapter 22 of the HCM, Exhibit 22-7 and the Federal Highway Administration (FHWA) study, Identifying and Assessing Key Weather-Related Parameters and Their Impacts on Traffic Operations Using Simulation (Reference 8).
Table 3.3 Weather Capacity Factors Scenario Season Weather Condition Roadway Capacity Speed 2 Summer Heavy Rain 90% 85%
6 Winter Heavy Snow/Ice 85% 65%
Based on the location of Clinch River and data obtained from NOAA (http://www.srh.noaa.gov/mrx/?n=oqtclimate) indicating average annual snowfall of 6.6 inches and 3 days per year with greater than 1 of snow, the winter adverse weather scenario (Scenario 6) considers ice as the limiting winter adverse weather condition and there is no effect on mobilization based on the need for snow removal from roadways or driveways.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 4.0 DEVELOPMENT OF EVACUTION TIMES Evacuation times are estimated for 90% and 100% of the evacuating vehicles to exit the EPZ boundary. A total of 10 scenarios were simulated in various weather, season, time, and network conditions to reflect the traffic conditions when the evacuation order is issued. Development of the evacuation times considered preparation activities, including the time to receive the notification and time to prepare to evacuate.
4.1. Trip Generation Time A random telephone survey of households within the EPZ was used to identify factors affecting the evacuee trip generation time (mobilization time) as well as other data to be used in the ETE analyses. The mobilization time is the major component of the total ETE when the EPZ population density is low and there is minimal traffic congestion, as is the case for the CRN Site.
The telephone survey provides a sound, documented basis for the trip generation times needed to develop the calculated ETEs.
With respect to trip generation time, the telephone survey was used to obtain data related to whether or not commuters would return home or evacuate directly from work; how long it would take commuters to travel home; and how long it would take to complete preparations at home and at work prior to evacuation. The data obtained from the telephone survey related to trip generation time is summarized in Tables 4.4, 4.5, and 4.6.
The evacuation trips consists of a sequence of events and activities. Each event (other than the notification alert) occurs at an instant of time, while activities are accomplished in series or parallel, over a period of time. The relevant events associated with the public's preparation for the evacuation trip are presented in Table 4.1. One or more activities are associated with each sequence of events as shown in Table 4.2.

Factors affecting the trip generation time include, but are not limited to the following:
- A commuter may or may not return home prior to evacuating.
- Households with a vehicle available for evacuation may or may not wait for a commuter to return home prior to evacuating.
- Transients within the EPZ may evacuate immediately without returning to their residence (With respect to transients, residence refers to their hotel, motel or campground.).

The minimum acceptable design objectives for coverage by an ANS is the capability for providing an alert signal and beginning an informational or instructional message to the population in the EPZ within 15 minutes and providing protective action recommendations, if appropriate. The coverage of essentially 100%
of the population in the EPZ who may not have received the initial notification must occur within 45 minutes. Based on the regulatory requirements and guidance in FEMA P-1028, the notification distribution used in this analysis is provided in Table 4.3.

It is assumed following notification and evacuation order, most businesses within the EPZ will shut down and most employees would leave work quickly and that residents dispersed within the EPZ performing daily activities will travel home. Table 4.4 shows the preparation time distribution to leave work/facility (Activity 2) from data obtained by those households that 55 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate responded to the telephone survey. This distribution is applicable for all commuters (those going home prior to evacuating, those evacuating directly from work, or those living outside the EPZ) and for residents to leave stores, restaurant, parks, and other locations within the EPZ.
Notification of the transient population is assumed to occur at the same time distribution as permanent residents. Those transients in campgrounds within the EPZ will receive an alert via the ANS.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Calculation of Trip Generation Time Distribution To compute the trip generation times, new time distributions (A, B, C, and D) are formed by applying a summing algorithm repeatedly to calculate the time distribution of an event that is dependent on two or more sequential activities. Table 4.7 shows the summing procedure and a description of each of the final trip generation distributions.
Table 4.7 Trip Generation Distributions Description Activities Distribution Description Sequence Time distribution of commuters evacuate directly, A employees live outside the EPZ, and transients 1+2 evacuate directly.
Time distribution of commuters/transients arriving B 1+2+3 home/residence.
Time distribution of residents wait for commuters and C transients arriving residence to begin the evacuation 1+2+3+4 trip.
Time distribution of residents without/do not wait for D commuters and transients at residence to begin the 1+4 evacuation trip.
The trip generation distributions describe the activities that take place before the evacuation trips begin. Distribution B is embedded within Distribution C because those residents are awaiting the return of the commuter and transients arriving at their residence before beginning their evacuation.
Statistical Outliers Some of the numeric responses are inconsistent with the overall pattern of results because the response either may be unrealistic or reflects a special population that need to be classified in a different population subgroup. These outliers may be valid responses that must be considered or unrepresentative and has to be dropped from the sample. To eliminate outliers:
a) Mean and standard deviation of the specific activity are estimated from the responses.
b) Median of the same data is estimated, with its position relative to the mean noted.
59 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate c) The histogram of the data is inspected and all values greater than 3.5 standard deviations from the mean are flagged and either considered as a valid response or dropped from the sample.
d) All values greater than 4 standard deviations from the mean are considered outliers and dropped from the sample.
e) Repeat steps "a" to "d".
Mobilization Time Distributions The overall (or total) mobilization distributions are constructed using the different mobilization activities modeled. This is done by using the data sets and distributions under different scenarios (e.g. households with/without commuters, households that wait/dont wait for commuters, commuters/transients evacuate directly, commuters/transients returning to home/residence prior to evacuating) according to the flow chart presented in Figure 4.1. The mobilization times obtained under different scenarios are used as direct inputs to the simulation model that lead to the ETE. Table 4.8 shows the trip generation distributions A, C, and D on the same time scale (elapsed time) and Figure 4.2 presents a comparison for the trip generation time distributions for the daytime scenarios.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 4.1.1. Permanent Residents and Transient Population Permanent residents are household residents, residents in special facilities, residents in medical facilities, employees at work, and children at schools within the EPZ. Census data were used to generate residential population and the population is distributed to zones of the network based on spatial locations. Major employers in the area were also geocoded and spatially associated with zones. The total number of employees is dependent on time of day and time of week. It is assumed that each employee commutes to work separately.
The transient population refers to people staying in a hotel, motel or a campground. According to different scenarios, the total transient population and locations which they are at varies by weather, time of day and time of year. The total number of transient population is divided into three groups: 1) Transients in their residence when the order to evacuate is received and will evacuate directly from hotel/model/campground; 2) Transients away from their residence when the order to evacuate is issued, but will return to their residence prior to evacuating; 3)
Transients away from their residence when the order to evacuate is issued that will evacuate directly from where they are. The first two groups are assigned to the corresponding zones where the hotel/motel/campground are located. The third group of transient population is distributed evenly within the EPZ.
Assumptions regarding transients are scenario-specific and are detailed in each scenario described in Section 1.3.
4.1.2. Transit Dependent Permanent Residents Transit-dependent permanent residents are those residents within the EPZ who do not have access to a vehicle or are dependent on help from outside the home to evacuate. The estimated number of transit-dependent permanent residents was adapted from the results of the random telephone survey of the households in the EPZ and surrounding area and are described in detail in Section 2.2 and Table 2.6. It is estimated that buses would be available to pick up transit dependent residents approximately 120 minutes (obtain drivers, brief drivers and mobilize to bus routes) after the order to evacuate and that would allow individuals to make their way to a bus route.
66 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate A subset of transit dependent residents includes people with disabilities and those with access and functional needs that live independent of a special facility. Information was requested from Roane County regarding residents who need assistance during an evacuation, but none was provided.
Because local emergency management agencies were not able to provide information regarding special needs individuals requiring assistance during an evacuation in the EPZ, the total number of vehicles needed was estimated as described in Section 2.2 and evenly distributed across the EPZ.
It is assumed that ambulances required to evacuate special needs individuals are capable of mobilizing to the home, loading the patient and begin the evacuation within 30 minutes of the evacuation order.

Special Facilities The presence of special facilities was researched during development of the ETE and it was determined that one facility, the Kingston Academy, currently exists within the EPZ. The Kingston Academy is a Psychiatric Residential Treatment Facility with living quarters and a capacity of 52 children between the ages of 5 and 17. The facility provides residential treatment and day treatment services. For this ETE, it is assumed the facility is at 90% capacity when an evacuation is ordered and the facility is ready to evacuate 75 minutes (60 minutes to prepare +
15 minutes to load vehicles) after the order to evacuate is issued. This results in an evacuation of approximately 47 residents from this facility. The number of transit-dependent residents in special facilities is summarized in Table 2.6.
Information on evacuation of the Kingston Academy is provided in Table 4.12.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 4.2. Evacuation Time Estimate Modeling This Section of the report includes a discussion of INTEGRATION, the traffic simulation model used in performance of the ETE and a summary of the key inputs, assumptions, outputs, and computational process associated with the simulation. INTEGRATION is a microscopic traffic assignment and simulation program with broad applicability to traffic simulation activities well-suited for performance of ETEs for nuclear power plants. The INTEGRATION software calculates a number of Measures of Effectiveness (MOEs) which are addressed by NUREG/CR-7002. The INTEGRATION software is listed in the U.S. Department of Transportations (DOT) Evacuation Management Operations (EMO) Modeling Assessment:
Transportation Modeling Inventory, developed to support selection of an appropriate model for use in evacuation analyses (Reference 1).
INTEGRATION is an integrated simulation and traffic assignment model that performs traffic simulations by tracking the movement of individual vehicles every 1/10 of a second. This allows detailed analyses of lane-changing movements and shock wave propagations. It also permits considerable flexibility in representing spatial and temporal variations in traffic conditions. The model also estimates the expected number of vehicle crashes using a time-based crash prediction model.
The INTEGRATION model computes a number of MOEs, including the network efficiency.
Efficiency evaluation of highway alternatives involves computing the average speed and vehicle delay. The average vehicle speed is computed as the average of all vehicle speeds, where the vehicle speed is computed as the trip distance divided by the trip duration. This model has been validated against state-of-the-art delay estimation procedures using queuing theory and shockwave analysis and against standard traffic flow theory and has been utilized for the evaluation of real-life applications.
The calibration of the INTEGRATION software entails two calibration efforts, namely calibration of the traffic demand and calibration of the network supply. The calibration of the traffic demand involves the use of the telephone survey results to construct a time-varying origin-destination (O-D) table. Different O-D demands were constructed for the different scenarios that were identified in Section 1.3. The second calibration effort entails calibrating four roadway parameters: saturation flow rate; free-flow speed; speed-at-capacity; and jam density.
71 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 4.2.1. Traffic Simulation Model Input Input files of INTEGRATION include files defining the topological relationship of the network, traffic control information and traffic demand data. The input files of the simulation include:
- Node File
- Link File
- Demand File
- Signal File
- Incident File
- Other supplemental Files The final network generated includes 1,824 nodes, 252 zones, and 3,312 links. Lane striping file is also included to define turning movements assigned to each lane at intersections.
4.2.2. Traffic Simulation Model Output INTEGRATION is flexible regarding simulation outputs and is capable of providing output files by network link, by vehicle, and by time sequences. At an aggregated level, INTEGRATION is capable of providing output results as: average vehicle stops/delays; total vehicles existing in the network; travel time/distance by vehicle class; volume/capacity ratio; and others. At individual link or vehicle level, INTEGRATION is capable of providing output results as:
Starting/ending time by vehicle and/or by link; link flow; link average travel speed; and queues on link, etc. Because the goal of the ETE is to estimate the time needed for the public to move out of the area of concern, the output file needed includes time and location information for each evacuating vehicle. By setting each evacuation vehicle as a probe vehicle, the appropriate output file records the trajectories of each vehicle. Data recorded in the output file are link and vehicle based. Once a vehicle exits a link, a record is written to the output file documenting time, trip ID, O-D, link ID, and vehicle speed. The data in the output file is then aggregated to calculate the travel time for each evacuating vehicle exiting the EPZ boundary by identifying the link ID at the boundary of the EPZ.
4.3. Evacuation Time Estimates for the General Public The output file provides a vehicle probe listing which chronicles the completion of each link a vehicle probe traverses. Every evacuating vehicle is marked as a probe in the simulation for 72 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate ETE. Two types of records can be produced, namely record type 11 and 21. Record type 11 is produced only once for each link and is generated at the time the vehicle departs the link.
Record type 21, in contrast, is produced every second the vehicle is on the link.
To compute the evacuation time, the following steps are adopted:
- 1. The phone survey asked questions such as whether or not the respondents will be at work, if yes, will they return home before evacuating, and how long will they need to prepare to evacuate. Such data are aggregated to develop trip generation times as described in Section 4.1. Several time distributions are generated to describe the time people need to prepare to evacuate. Such distributions are statistically aggregated to obtain the overall patterns of the time needed to prepare to evacuate.
- 2. The simulation starts with a 45 minute background traffic simulation to ensure equilibration prior to initiating the ETE simulation.
- 3. Following this 45 minute period, the background traffic gradually decreases and traffic volumes start to convert into evacuation traffic as INTEGRATION begins to generate and load vehicles into the network based on the trip generation time distribution.
- 4. At 90 minutes the background traffic will stop entering the network.
- 5. The simulation continues to simulate each vehicles movement and traffic condition in the network.
- 6. The output file records the trajectory of each vehicle and information such as origin, destination, starting time, and arrival time, etc.
- 7. The road links at the boundary of the EPZs are used to identify occurrence of each vehicle on the links. The travel time on such links are divided into 2 parts proportional on the length of the section of that link located within and out of the boundary.
- 8. The time spent traveling is documented and aggregated. The ETE is estimated for 90%
and 100% of the vehicle exiting the EPZs.
The ETE for the evacuation of the general public are provided in Tables 4.13 and 4.14.

Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 5.0 OTHER CONSIDERATIONS The preceding sections describe the methodology and approach to calculating the ETE. In addition to the calculation of an ETE, there are other considerations that need to be addressed in this and future ETE studies. These considerations, as appropriate, are described below.
5.1. Development of Traffic Control Plans In the event of an evacuation of the EPZ, OROs would establish ACPs and Traffic Control Points (TCPs) as necessary to support the evacuation. It is assumed that ACPs can be staffed within approximately 90 minutes of the advisory to evacuate. Activation of ACPs prior to 90 minutes could delay commuters returning from areas outside of the EPZ. Therefore, it is recommended that ACPs be established 90 minutes following an advisory to evacuate to allow commuters sufficient time to return home and prepare for an evacuation.
ACPs should be established as follows to restrict in-bound traffic flow toward the CRN Site:
- 1. Prior to 45 minutes after the evacuation order is issued, background and pass-through traffic is running normally in the network.
- 2. From the time an evacuation order is issued until 90 minutes after the order is issued, background traffic begins to diminish as traffic exits the EPZ and the ACPs begin to prevent inbound traffic from entering the EPZ. The evacuating traffic begins to increase at the rate of the time distribution to get ready (see section 4.1).
- 3. The background and pass-through traffic stops entering the EPZ 90 minutes after the evacuation order is issued.
Based on the low population of the EPZ, the limited number of vehicles involved in the evacuation, the relative simplicity of the roadway network within the EPZ, and the absence of congestion observed during the traffic simulation modeling, the need to develop more detailed traffic control plans to support an evacuation is not considered necessary at this time. As future ETE studies are conducted additional consideration should be given to the need for a more detailed traffic control plan based on future potential changes to the roadway network, the potential for increased populations within the EPZ and the potential for increased congestion observed during traffic simulation modeling.
75 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 5.2. Enhancements in Evacuation Time Guidance presented in NUREG/CR-7002 suggests that an evaluation of potential enhancements that could reduce the evacuation time be limited to those roadways or intersections of the EPZ that impact the ETE the greatest (Reference 4). These evaluations typically include intersections and roadways that experience LOS F conditions for some period of time. Based on the absence of congestion observed during the traffic simulation modeling, the need to develop enhancements that may reduce evacuation times would have little, if any, benefit. As future ETE studies are conducted, additional consideration should be given to the need for enhancements that may reduce evacuation times.
5.3. State and Local Review State and local authorities were involved in the development of the ETE. Interactions began with a kick-off meeting in Knoxville in January 2014 during which the regulatory requirements, the process used to develop the ETE and the associated data and information needs were discussed. The meeting was attended by representatives of the following State and local agencies and private sector support organizations:

- American Red Cross of East Tennessee Following the kick-off meeting, a telephone survey instrument was prepared and provided to the TEMA for review and comment, resulting in several modifications. Each agency approved of the instrument prior to initiating the telephone survey.
TEMA and Roane County provided assistance with completing data collection related to the permanent resident and transient populations, schools, major employers, transportation resources, transit-dependent residents and hotels, motels and campgrounds in the EPZ.
5.4. Reviews and Updates Details related to updating this ETE are included in Sections 5.6 and 5.7 of this report.
5.5. Reception Centers and Congregate Care Centers The specific locations of reception centers have not yet been identified. Because of the absence of a school population and the limited number of transit-dependent permanent residents, it is not anticipated that multiple trips will be necessary to evacuate the transit dependent population. Therefore the location of these facilities and the logistics of offloading passengers will not impact return trips to the EPZ or the evacuation time.
5.6. New Reactors Part 5 of the Early Site Permit Application (ESPA) being submitted for the CRN Site includes two (2) Emergency Plans (Part 5A and Part 5B) for review by the NRC. Part 5A will address a site boundary Emergency Planning Zone (EPZ) and Part 5B addresses a 2-Mile EPZ. The final EPZ size will be determined at the time the Combined License Application (COLA) is submitted.
This ETE is prepared in support of the 2-Mile EPZ Emergency Plan. In the event the site boundary EPZ is selected for the CRN Site, the Tennessee Valley Authority (TVA) has 77 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate proposed an exemption from the requirements to perform an ETE and an update to this ETE will not be necessary.
Because the CRN Site is a greenfield site, as described in NUREG/CR-7002, emergency response plans are not in place, evacuation plans have not been approved and tested by local authorities and the locations of congregate care and reception centers have not been established. These conditions necessitate that the development of the ETE analysis be coordinated with the development of the emergency response program being prepared during the licensing phase (Reference 4). For the CRN Site, development of the offsite emergency response program will occur beginning with the development of the COLA. In the event a 2-mile EPZ is selected, assumptions used in the ETE must be consistent with the assumptions and proposed resources and infrastructure identified within the emergency response plan to provide an accurate ETE. An ETE update for the COLA is expected to be developed based on the most recent decennial census data projected to the year the license application will be submitted.
5.7. Early Site Permits This ETE was developed in support of the CRN Site ESPA. The ETE serves to satisfy the requirements of 10 CFR 52.17(b)(1), which states that the site safety analysis report identify physical characteristics of the proposed site, such as egress limitations from the area surrounding the site, that could pose a significant impediment to the development of emergency plans and if physical impediments are identified, the application must identify measures that would, when implemented, mitigate or eliminate the significant impediment. This ETE did not identify physical characteristics of the proposed site that could pose a significant impediment to the development of emergency plans.
As described in Section 5.6 and in Section 5.7 of NUREG/CR-7002, data and information is expected to be updated, as appropriate, to ensure up-to-date information is used to develop the ETE when the COLA is submitted.
78 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate 6.0 GLOSSARY Count Station - Specific location on a roadway where traffic count surveys are conducted.
Demand Estimation - The total number of evacuees by population group including vehicles.
Emergency Response Planning Areas (ERPAs) - Defined areas that constitute the EPZ and for which emergency response plans have been developed. These areas are typically defined by geographic or political boundaries to support emergency response planning and may also be referred to as subareas, protective action areas, or other local terminology.
Evacuation Tail - A small portion of the population that takes a longer time to evacuate than the rest of the general public and is the last to leave the evacuation area. The tail generally conforms to about the last 10 percent of the population.
Keyhole Evacuation - An evacuation of the 2-mile radius around an NPP and the downwind sectors forming a keyhole configuration.
Link - A segment of roadway between two nodes.
Loading Curve - The rate at which vehicles are entered onto the roadway network.
Measure of Effectiveness (MOE) - Statistics used to describe performance. As applied in this document, these include output data that provide key performance characteristics of the roadway network and the evacuation time.
Node - An identification designator used to connect links in a roadway network model or to apply input data onto the network. Nodes are at intersections, ramps, etc., and contain characteristics such as traffic control and may be used as input points to assign loading of vehicles.
Permanent Resident - All people having a residence in the area.
Roadway Capacity - The maximum rate at which vehicles can be reasonably expected to traverse a point or uniform section of roadway during a given time period under prevailing conditions.
Shadow Evacuation - Evacuation of persons from areas outside any officially declared evacuation zone.
Special Event - An activity where large transient populations are present for a limited period of time.
79 Revision 0
Clinch River Nuclear Site Early Site Permit Application Part 5B, Emergency Plan Evacuation Time Estimate Special Facilities - Facilities where residents are confined or dependent upon facility personnel for transportation, including nursing homes, assisted living centers, hospitals, jails, prisons, and other similar facilities.
Staged Evacuation - A protective action where one area is ordered to evacuate while adjacent areas are ordered to shelter in place until ordered to evacuate.
Transient Population - Tourists, shoppers, employees, etc., who do not reside within the EPZ, and other people temporarily visiting the EPZ.
Trip Generation Time - Time elapsed for each population group from when the evacuation order was disseminated until the time when the evacuation trip actually begins (e.g., when the car leaves the driveway).
