ACNGS-PSAR 13.3 EMERGENCY PLANNING 1 13.3.1 ITERODUCTION This section describes the preliminary plans for responding to emergencies at , the Allens Creek Nuclear Generating Station, Unit 1 (ACNGS) in accordance with recently revised 10CFR50 Appendix E. Detailed plans will be provided in the Final Emergency Plan as part of the Final Safety Analysis Report. The purpose of this section is to provide reasonable assurance, by seans of describing preliminary plans, that adequate final emergency plans can be developed and that these preliminary plans are compatible with the ACNGS facility and its location. The overall objective of emergency planning for the ACNGS will be to provide dose savings for a wide spectrum of postulated accidents that could produce offsite doses in excess of Protective Action Guides. Planning vill include a wide range of protective actions designed to prevent or mitigate the potential consequences of an accident. Protective actions will range from simple notification of certain offsite organizations that an Unusual Event is taking place or has occurred to the -full activation of offsite organizations and evacuation of the public in the event of a General Emergency. The ACNGS Final Emergency Plan will be part of an overall coordinated ! emergency response plan involving Federal, State and local emergency response 55 organizations. State and local emergency plans approved by the Naclear Regulatory Commission will be in place prior to operation of the ACNGS. Emergency planning for the ACNGS will include, but not be limited to, the following important elements.

1) The establishment of Emergency Planning Zones (EPZ) for the plume exposure .ind the ingestion pathways.
2) The use of emergency action levels to determine the need for notification and emergency response. These action levels will be based on plant and offsite conditions which would indicate potential or actual hazards.
3) The use of the same event classification system by Federal State and
  • local organizations and the licensee.

l

4) The administrative and physical means to preuptly notify and instruct. the public and appropriate Federal,' State and local emergency response organizations.
5) The ' establishment of emergency facilities and equipment to assess and monitor an accident and to carry out protective sensures and recovery operations.

l l i l l i 13.3-1 . Am. ' No. 55,(1/81)

ACNGS-PSAR

6) A program to disseminate to the public information about how they will be notified in the event of an accident and what protective actions might be taken.
7) A comprehensive program to provide scheduled training to appropriate employees of the licensee and to persons associated with offsite organizations whose assistance may be needed in the event of an emergency.
8) Provisions for conducting drills and exercises to thoroughly test the preparedness of Federal, State and local organizations and Houston Lighting & Power Company (HL&P).
9) Agreements with of fsite organizations to provide a wide range of services tnat may be needed to augment the HL&P organization.

Emergency planning for the ACNGS will include detailed planning for evacuation of the public within the plume exposure EPZ (i.e., within about 10 miles). Adequate egress routes which will facilitate timely evacuation of the plume exposure EPZ in the event such action is deemed necessary have already been identified. A preliminary study has been performed which verifies the feasibility of conducting timely evacuation of the public within all sectors of the plume exposure EPZ. This study, which is provided as Appendix 13.3B to this section, takes into consideration present and projected populations, adverse weather conditions, transient populations and special facilities. 13.3.2 EMERGENCY ORGANIZATION 55 The organization for responding to emergencies at the ACNGS will initially consist of the on-duty operating staf f, will be augmented by of f-duty plant and other designated EL&P personnel and Federal, State and local response organizations. This organization may also be augmented by additional offsite resources and support. A major objective of emergency planning for the ACNGS will be to ensure that responsibilities are unambiguously defined, that adequate staffing is maintained, and that timely augmentation of response and recovery capabilities is available. The final ACNGS Emergency Plan will describe in detail the emergency response and recovery organization, its functions, responsibilities and authority. 13.3.2.1 Onsite Emergency organization The ACNGS plant organization for normal operations will be trained and qualified to adequately respond to a wide spectrum of emergency conditions. The minimum shif t crew will consist of a sufficient number of qualified personnel to perform at least the following functions: t Plant system operations Accident assessment ~ Notifying and communicating with offsite organizations l l l 13.3-2 Am.

       -       Record keeping Houston Lighting '&' Power Company will establish an onsite emergency response organization, under thi direction of "a'n Emergency Director, capable of responding to an emergency situation. The personnel comprising the onsite emergency organization may be from the plant or site staffs, from the HL&P corporate organization, or from outside organizations with whom HL&P has made prior arrangements. These personnel and their alternates will be either onsite or on call continuously for the duration of the emergency.

The ACNGS emergency organization under the direction of an Emergency Director will consist, as a minimum, of persons capable of functioning in the following areas: Plant operations -

        -       Technical support Operations support
        -       Radiation protection Public affairs                                                             55
        -       Administrative and logistics support l         The functions are discussed further in the following sections. In addition, personnel in such areas as maintenance, security, quality assurance, engineering and construction may be called upon by the Emergency Director to respond. The offsite personnel can be available at the ACNGS within eight hours following the initiation of response activities. The final ACNGS Emergency Plan will describe in detail the onsite emergency orgsnization.

l 13.3.2.1.1 Emergency Director The Emergency Director is the designated individual in charge of all accident mitigation efforts at the site. Other individuals will be designated as alternates to provide relief for the Emergency Director. l An Operating Supervisor, who is on duty in the plant at all times, is the individual in the immediate position'of authority who has responsibility for safe plant operation. The Operating Supervisor is responsible for the initial evaluation of abnormal or emergency conditions and for initiating response e f forts. Upon the occurrence of an event which indicates an actual or potential emergency situation, the Operating Supervisor will immediately l l l I ' 13.3-3 Am. No. 55, (1/81)

ACNGS-ESAR assume the role of Emergency Director. The Emergency Director will classify the event, initiate appropriate emergency actions, implement emergency procedures as necessary, and notify appropriate organizations and personnel. Emergency procedures will detail the specific actions to be taken by the Emergency Director. In the event that the Operating Supervisor is incapacitated, the immediate role of the Emergency Director will assumed by the Watch Supervisor Nuclear. The Operating Supervisor will fill the role of Emergency Director until properly relieved by that individual designated to serve as Emergency Director through the remainder of accident response activities. HL&P presently anticipates that this individual will be the Plant Superintendent. 13.3.2.1.2 Plant Operations The control of plant systems during an accident will be performed in the control room. During an accident, full shif ts of appropriately trained and licensed personnel will occupy the control room. 13.3.2.1.3 Technical Support An onsite Technical Support Center (TSC) will be established at the ACNGS to provide technical support and recommendations regarding emergency actions. The TSC will be staffed with personnel qualified in the areas of reactor engineering, thermal hydraulics, mechanical engineering, instrumentation and control, chemistry, radiochemistry, overall plant design and engineering, and electrical systems. A TSC Supervisor will be designated to direct the 55 activities of the TSC staff. The TSC staff will be available to occupy the TSC within two hours of notification. H.&P anticipates that NRC representatives will be present in the TSC during the course of an accident. 13.3.2.1.4 Operations Support An onsite Operations Sapport Center (OSC) will be established at the ACNGS as an assembly area for plant support personnel. Personnel assigned to the OSC i will have expertise in at least the areas of plant chemistry, electrical systems, mechanical systems, instrumentation and control and health physics. An OSC coordinator will be designated to coordinate the activities of the individuals assembled at the OSC. 13.3.2.1.5 Radiation Protection A Radiation Protection Manager (RPM) will have responsibility for directing the activities of plant and near-site radiation monitoring teams, performing radiological assessments and reviewing results and findings. The RPM will communicate with and coordinate activities with the offsite Radiological Emergency Manager. 13.3-4 Am. No. 55, (1/81) l

The Radiological Emergency Manager (REM) will be responsible for directing the activities of of fsite radiological monitoring teams, performing offsite dose calculations and projected dose estimates and reviewing results and findings. The REM will represent Houston Lighting & Power Company in interfacing with other agencies performing of fsite monitoring. The REM will communicate with and coordinate activities with the onsite Radiation Protection Manager and operations personnel in order to be kept knowledgeable of the plant status. 13.3.2.1.6 Public Affairs Houston Lighting & Power Company will designate a spokesperson to interf ace with news media personnel, release public information and interface with spokespersons of other response organizations. The HL&P spokesperson and alternates will be trained in conducting news media briefings and public speaking. Public Af fairs personnel will have direct communications with the plant in order to be kept knowledgeable of the plant status. 13.3.2.1.7 Admi.nistrative and Logistics Suppore If requested by the Emergency Director, designated HL&P personnel will be called into service, to perform activities in the areas of purchasing, stores, insurance claims, accommodation and commissary needs, clerical help, transportation, finance, human resources, communications and other logistics requirements. Furthermore, the entire HL&P organization will provide, at the request of the ACNGS Emergency Director, all available manpower, equipment and facilities to assist in responding to the emergency. 55 13.3.2.2 Recovery Organization As plant systems become stabilized and any consequences of an accident are mitigated, accident response gradually changes to accident recovery. Activities associated with recovery could take place over a long period of time and could involve a wide range of support and resources. Furthensore , recovery activities could very well begia before emergency response has terminated. 13.3.2.2.1 Recovery Manager In the event recovery activities are required following an accident at the ACNGS, a designated HL&P individual, with alternates, will assume the role of Recovery Manager who will be in overall charge of these activities.

13.3.2.3 Of fsite Government Agencies A major element of ACNGS emergency planning will be the mutually supportive role of Federal, State and local response organizations. A wide range of support and resources are available from each of these levels of government to assist ML&P in ACNGS emergency response and recovery operations.

13.1.2.3.1 Federal Agencies 55 The following Federal agencies are available to provide support to HL&P in the event of a serious accident at the ACNGS: a) Nuclear Regulatory Co:enission (NRC) If called upon to support eiergency response at the ACNGS, NRC operations ic and around the plant will be managed by the Regional Director of the NRC's Region IV office in Arlington, Texas. The NRC's role will include monitoring the event, independently evaluating the emergency and providing technical ! advice and assistance to RL&P if requested or required. The Regional Director will be supported by the NRC 3perations Center in Bethesda, Maryland. A letter of agreement / understanding with NRC Region IV is provided in Appendix 13.3A. l l b) Department of Energy (DPE) The DOE will provide radiological environmental surveying and monitoring support through its Radiological Assistance Program (RAP) and the Federal Interagency Radiological Assistance Plan (IRAP). A letter of agreement / understanding with DOE is provided in Appendix 13.3A. 13.3-7 Am. No. 55, (1/81)

l e ACNGS-PSAR c) Other Agencies A variety of emergency resources are available from such agencies as the Environmental Protection Agency, the Department of Health and Human Services, the Federal Emergency Management Agency (FEMA), the Bureau of Radiation Health and national laboratories. The role of Federal agencies is to be defined in a national contingency plan presently under development by FEMA. In the final ACNGS Emergency Plan, HL&P will provide a detailed description of the role of Federal agencies, as well as any necessary letters o f agreement / understanding. 13.3.2.3.2 State Agencies In the State of Texas, State-level response to any type of emergency is the responsibility of the Governor's Division of Disaster Emergency Services. These responsibilities are carried out by the Disaster Emergency Services Council (DESC), which is presently composed of representatives from 33 major l State agencies. By gubernatorial appointment, the Director of the Texas Department of Public Safety (DPS), an agency represented on the DESC, chairs the DESC. The DPS operates several district offices throughout the State. In the event of an emergency in a district, State response would be managed from the district of fice through its District Disaster Committee (DDC). The DDC is composed of field representatives from each of the State agencies represented on the State's DESC. The DPS District Commander chairs and directs the DDC. 55 In the event of an emergency at the ACNGS requiring the notification of State agencies, the DPS District Of fice in Houston, Texas will be the first agency l contacted and the DOC will be activated if necessary. If greater State response were required, the DESC in Austin, Texas will be activated. The DESC operates from the State Emergency Operations Center (EOC) in the DPS headquarters in Austin, Texas. Although as many as 33 State agencies could be l called upon to respond to an emergency, the primary agencies with respect to ! the ACNGS are the Texas Department of Health, the Department of Public Safety, and the Texas Parks and Wildlife Department. The response of State agencies will be detailed in the State Emergency Plan and Standard Operating Procedures which will be approved by the NRC and FEMA prior to commercial operation of the ACNGS. a) Texas Department of Health f The Texas Department of Health, Division of Occupational Health and Radiation ! Control (OH & RC), is the lead State agency for coordination of State response to a radiological emergency. Support activities of the OR & RC include environmental surveying and monitoring, dose assessment, dose projections, health physics, State public affairs onsite, and recommending protective actions. Representatives from OH & RC will operate onsite in the event of a i i l 13.3 Am. No. 55, (1/81) i l i

ACNGS-PSAR serious accident at the ACNGS. The OH & RC is also responsible for preparation of State emergency plans for fixed nuclear facilities and for coordinating th& State's involvesent in exercises, drills and radiological training. A letter of agreement / understanding from the OH & RC is provided in Appendix 13.3A. Other divisions within the Texas Department of Health are available to provide such services as the coordination of medical services and the control of foodstuffs, milk and crops. b) Texas Department of Public Safety l The Texas Department of Pub?.tc Safety (DPS), through its district offices and headquarters, is responsibl' for the overall management of the State's response to emergencies. In addition, the DPS is responsible for coordinating State communications, public information (offsite), law enforcement, traffic control and transportation. c) Texas Parks and Wildlife Department The Allens Creek Lake and State Park will be operated by the Texas Parks and Wildlife Department (TP & WD). Two TP & WD attendants will be assigned to the park, with at least one of them present in the park at all times. During the day, collgate attendants and maintenance and groundskeeping personnel will also be present in the park. The on-duty park attendants will receive all emergency notifications from the plant and are responsible for directing park 55 i evacuation. 13.3.2.3.3 Local Agencies I In the State of Texas, the County Judge has the ultimate authority for emergency operations within each county. The County Judge is the local official responsible f or authorizing emergency response and protective actions. EmerFency response and pro *ec tive actions are implemented under the direction of the County Sheriff. The ACNGS is located in Austin County, Texas with the plume exposure Emergency Planning Zone (about 10 miles) extending into portions of Fort Bend, Wharton, Colorado and Waller Counties. The Austin County Sheriff's Department is the primary local response agency for the ACNGS and will provide, as a minimum the following support services: l

                 -  A major communications link between the ACNGS and participating l                    State and local organizations l
                 -  Receive initial emergency notification (a dispatcher is on duty 24 hour s)

                - Implement protective actions Traffic control and law enforcement Letters of agreement /understandig with the five County Sheriff's Departments of the counties affected by the plume exposure EPZ are provided in Appendix 13.3A.
Approximately four miles from the site of the ACNGS is the city of Wallis, Texas. Due to their proximity to the site, it is quite likely that the first on-scene response personnel will be the resident Deputy Sherif f in Wallis, the Wallis police or Wallis Volunteer firemen who will have been notified by the County Sheriff. These personnel would most like'.f be the first to implement offsite protective measures. Letters of agreecant/ understanding with the Wallis Police Department and Wallis Volunteer Fire Deyartment are provided in Appendix 13.3A.

Other services available at the local level include rescue, ambulance service, medical treatment, shelter and transportation. Local emergency plans detailing specific local response activities will be prepared and approved by the NRC before the ACNGS begins :ommercial operation. 13.3.2.4 Additional Support and Resources 55 HL&P will make arrangements with other organizations and individuals which can be relied upon to provide assistance in an emergency. These may include, but are not limited to, the following:

                  -   Laboratories - e.g. , analytical ar alysis of monitoring samples

    .' 3. 3. 2. 5       Planning Resoonsibiliev Bouston Lighting & Power Company, the State of Texas and local counties presently have qualified personnel assigned responsibility for the development of fixed nuclear facility emergency plans. The final ACNGS Emergency Plan, and the State and local plans approved by the NRC and FEMA, will describe those persons responsible for maintaining, reviewing, distributing and updating applicable energency plans. HL&P will , ensure that these responsibilities are executed.

4 13.3.3 EMERGENCY CLASSIFICATION SYSTEM Emergency conditions at hCNGS will be classified into four categories which will cover the entire spectrum of probable and postulated accidents. The four class-- will be: Unusual Event Alert Site Area Emergency General Emergency The Unusual Event and Alert categories are intended to provide early and prompt notification to the onsite and offsite emergency response organizations (see 3ection 13.3.2) that minor events have occurred or are in progress which could lead to more serious consequences if the plant status is in some way further complicated or which might be indicative of more serious conditions 55 which are not yet fully realized. The Site and General Emergency categories are intended for more severe situations, which indicate that significant of fsite ef fects are likely and require immediate action from both onsite and of f site enargency response organi:ations. The identification of a Site or General energency should be assessed as quickly as possible and steps taken to mitigate the event and its effects and returning the plant to a safe status. The decision to declare a particular emergency class is the responsibility of the Operating Supervisor at ACNGS, as Emergency Director. His decision will be based, to the extent feasible, on readiy available information about plant l and offsite conditions which would indicate potential or actual hazards. The final ACNGS Emergency Plan will specify the criteria for declaring each emergency classification, as well as the previsions for upgrading the classification level and the corresponding response in the event of change of-l severity of the emergency condition. f- 13.3.3.1 Unususi Event . Events within the Unusual Event class will represent of f-normal conditions in and around the plant. These events will not, by themselves,_ constitute r I l 1 t 13;3-11 Am. No. 55, (1/81)

ACNGS-PSAR

   -;gnificanc emergency conditions and will have no of fsite radiological consequences. Some of these events could, however, indicate a potential degradation in the level of plant safety and/or could escalate to a more severe condition if appropriate onsite action is not taken.

The primary purpose of notifying offsite agencias of an Unusual Event is to put the of fsite response organization on standby, provide them with current information and provide unscheduled testing of the of fsite communication link. An Unusual Event classification would initiate the augmentation of the onsite response resources to assist in the assessment and mitigation of the event. Recommendations will specify that no offsite actions are necessary. 13.3.3.2 Alert Events within the Alert class will indicate an actual or potential degradation in the level of plant safety. The purpose of declaring this emergency class will be to assure that of fsite emergency personnel and monitoring teams are ready to respond if needed. This class may also serve as an unscheduled test of the activation of the onsite and of fsite emergency response facilities and the related communication systems. The response of offsite agencies will be to bring key elements of the emergency response organization into standby status, including offsite monitoring teams. This class of emergency will also initiate the activation of the Technical Support Center and the Operations Support Center. The near-site Emergency Operations Facility will be brought to standby status. 55 In addition to the manning of the onsite response facilities, this emergency class might require that radiological and meteorological assessments be made and reported to the offsite agencies. No public action would be recommended in this emergency class. As a precautionary measure, visitors to the Allens Creek Lake and State Park will be evacuated. 13.3.3.3 Site Area Emergency Events within the Site Area Emergency class involve actual or probable major failures of plant functions needed for protection of the public. The purpose of declaring the Site Area Emergency class is to assure the manning of all emergency response facilities, the dispatching of monitoring teams and the assembling of personnel required for evacuation if such action becomes necessary. Declaration of this emergency class will also be used as a means of informing the offsite agencies and the public that significant events are taking place. The response of offsite agencies following such a declaration will be to consider implementing protective actions and to assess information 13.3-12 Am. No. 55, (1/81)

ACNGS-PSAR from ACNGS and of fsite monitoring teams. Protective action might include notification of the public withir *he 10-mile EPZ and instructions to seek shelter or evacuate. Meteoro',gicat conditions and dose estimates will be made and provided to the offsste agencies. Assessment of plant safety and release projections will be c mpiled for use in consultation with offsite a ge ncie s. 13.3.3.4 General Emergency Events within the General Emergency class involve actual or imminent substantial core degradation or melting, with potential loss of containment integrity and/or releases of large quantities of radioactive material to the environment. The purpose of declaring the General Emergency class is to initiate predetermined protective actions for the public and additional measures as indicated by event releases or potential releases and to provide continuous assessment and information on events to of fsite agencies. Upon declaration of this emergency class, all local, State and Federal response organizations will be fully activated. These agencies will use onsite assessments and dose estimates, in addition to offsite monitoring data, to implement the necessary protective actions. Public notification will be recommended. Protective actions might include instructions to seek shelter, the evacuation of persons within the 10-mile EPZ, and/or the distribution of thyroid protective drugs. The declaration of the General Emergency class will require that all of the 55 ACNGS emergency rer?cuse facilities be manned, appropriate onsite protsetive actions be taken and monitoring teams be dispatched. Meteorological conditions and dose estimates will be provided to the offsite agencies. Assessments of plant safety and release projections will be compiled for use in consultation with offsite agencies. i 13.3.4 NOTIFICATION AND COMMUNICATION 7 Notification is the initial contact of response organizations and/or the l public by the ACNGS, either directly or through another organization, which alerts these organizations and/or the public that an event has occurred at the plant which indicates an actual or potential emergency condition. The notification process proceeds promptly, is of short duration and transmits a brief, but essential, amount of information. Notification is followed by massages providing more information, instructions to the public and/or specific recommendations. Emergency planning for the ACNGS will include provisions for the prompt notification of appropriate HL&P, State, local and Federal response pe; nel and organizations by the ACNGS. Sufficient communie4t .on capabilities, i including backup systems, will be in place to effec; prompt notification of all response organizations. Plans and procedures will be established with l' respect to primary contact within response organizations and means of contact, i backup communications, the content of initial and follow-up messages and 1 13.3-13 Am.

T l ACNGS-PSAR 13.3.6 ACCIDENT ASSESSMENT The ACNGS will have adequate systems, equipment, facilities and procedures to pronptly identify and monitor actual or potential consequences of an emergency condition within and outside the site boundary. Emergency action levels will be utilized to determine the event classification and need for protective actions. The final ACNGS Emergency Plan and implementing procedures will describe in detail accident assessment methods and criteria. 13.3.6.1 Emergency Action Levels The ACNGS will utilize a system of Emergency Action Levels (EAL's) for l accident assessment. EAL's are particular in plant conditions, instrument readings and onsite and offsite monitoring results that indicate an roergency event has occurred. The EAL's provide a basis for categorizing the event into one of the following classifications: Unusual Event, Alert. Site or General Emergency. The EAL's also provide the basis for determining the need for notification and participation of offsite organizations and for determining when and what type of protective measures should be implemented. The EAL's for the ACNGS will be agreed upon by EL&P and State and local response organizations and approved by the NRC. EAL's will be presented in the final ACNGS Emergency Plan. 55 13.3.6.2 Assessment Capability The ACNGS will have the capability and resources to provide initial evaluation and continuing assessment of an emergency event throughout the course of an accident. This capability will include post-accident sampling capability, radiation and effluent monitors, in plant iodine instrumentation and containment radiation monitoring. Assessment of in-plant conditions will be coordinated in the Control Room with the assistance of the Technical Support l Center. Information provided by the Safety Parameter Display System (see Section 13.3.5.6) and the real-time meteorological instrumentation will be major tools in the accident assessment process. This information will be available in the Control Room and Technical Support Center, as well as in other emergency facilities. The ACNGS will have the capability to monitor the area within and outside the site boundary and to estimate and project radiation doses. Under the ! direction of the Radiological Emergency Manager (see Section 13.3.2.1.5) I operating out of the Emergency Operations Facility (see Section 13.3.5.3), radiological monitoring teams will be dispatched within the plume exposure-EPZ. The data gathered by the monitoring teams will aid in determining the severity of the accident. The EOF, as well as other emergency facilities, will have available data from real-time meteorological monitoring instrumentation for use in computerized dose projection. The capability to l manually project doses will be provided. l l I i l l 13.3-21 Am. No. 55, (1/81)

ACNGS-PSAR 13.3.7 PROTECTIVE MEASURES Protective actions will 5e taken as appropriate to prevent or mitigate the potential consequences to individuals during or following a radiological incident a t ACNGS . Measures taken within the ACNGS site boundary will be the responsibility of HL&P, but may include some assistance by offsite organizations. The implementation of protective measures outside the ACNGS site boundary will be primarily the responsibility of State and local emergency organizations. Those offsite protective actions may be dependent upon receipt by the of fsite organizations of applicable meteorological and radiological data and recommendations from ACNGS. The type and extent of onsite and of fsite protective actions will be based on the severity of the emergency and will be related to the event classifications presented in Section 13.3.3. 13.3.7.1 Onsite Protective Measures The implementation of all oneita prot 3ctive measures will be the responsibility of the J.CNGS Emergency Director. The decisions made by the Emergency Director will reflect the severity of the emergency as it relates to the health and safety of those persons inside the ACNGS site boundary. His 55 decision in some cases may also relate to the health and safety of individuals outside the site boundary, such as during the removal of radioactive material. The specific criteria and detailed protective actions for onsite personnel will be specified in the final ACNGS Emergency Plan and implementing procedures. The criteria for developing protective measure includes exposure control, contamination control and personnel accountability. During emergency conditions, measures will be taken to keep exposures within 10CFR20 limits. Such measures might involve respiratory protective equipment, protective clothing, radioprotective drugs or any other health physics procedures which would apply to exposure control in emergency situations. The primary protective measure for onsite personnel not engaged in emergency functions will be prompt evacuation from areas which may be affected by j significant radiation, contamination or airborne radioactivity. Fer personnel ! who are engaged in emergency functions, it may be necessary in special cases to use the Environmental Protection Agency Protective Action Guide 1, which allow emergency workers to incur exposures greater than those during normal conditions. The decision to allow the use of these emergency exposure levels is the responsibility of the Emergency Director. The control of radioactive contamination within the site boundary will- be i maintained to the extent feasible through the use of measures delineated in L the ACNGS Health Physics procedures. These measures may include the restriction of access to areas within the plant, as well as the monitoring and

                                                                 ~

decontamination, as needed, of personnel and equipment which are moved from those areas. In the event of significant radioactive contamination outside i the fenced security area, but within the ACNGS ' exclusion area, access to the exclusion area will be strictly controlled by HL&P. There.will be no 13.3-22 Am. No. 55, (1/81)

Onsite evacuation procedures will include provisions for reliable personnel accountability. The evacuation of local areas within the site will be initiated by either area radiation monitor alarms or the in plant public address system. 'Through the use of assembly areas, non-essential personnel will be accounted for to assure . that all are removed from areas of significant exposure oor contamination hazard. Provisions will be made for the control of visitors or contract

personnel throughout the course of the emergency.

13.3.7.2 Offsite Protective Measures i 13.3.7.2.1 Protective Measures for the Plume Exposure Pathway Emergency Planning Zone i The plume exposure EPZ is an area about 10 miles in radius around the ACNGS. The principal exposure sources in this EPZ are: (1)'whole body external exposure from the plume and deposited material, and (2) inhalation. The principal protective actions are notification and shelter and/or evacuation. Use of the thyroid blocking agent, potassium iodide, will be censidered.

The Austin County Sheriff's Department will initiate the implementation of 55.
protective measures within the 10-mile plume exposure EPZ. Specific actions to be taken will be described in the Emergency Operations Plans and procedures for each of the counties. The actual implementation of protective measures in each of the counties with portions in the 10-mile EPZ will be carried.out by -

the respective County Sherif f's Departments. Protective measures will be implemented initially in' the areas directly af fected by the plume from the plant as well as areas which would be affected if the plume changed direction. ML&P envisions an area of roughly a 'teyhole" i shape, consisting of an area immediately around the plant ranging from about 1-3 miles, plus a sector encompassing the lplume and extending radially outward - from the plant to a distance determined from-dose projections. The area immediately around the plant in which actions.might be taken includes the Allena Creek Lake and State Park. The only applicable protective measures for the lake and park areas are notification and evacuation. .For al1 events

                                                                                         ~

in the four classifications (Section 13.3.3), th'e Texas Parks & WildlifeE Department attendants on duty in the Park. will be notified. For events in the Alert, Site Area and Generst Emergency classes, the Emergency Director will recommend the Lake .and State Park be evacuated; if' only as -a precautionary: measure. ' The Texas Parks & Wildlife Department attendants are. responsible' for - notifying and evacuating the public from lake and park. areas.' The park attendants will have the assistance of coll gate attendants and maintenance [ and groundskeeping personnel during the day when the park is most occupied.

ACNGS-PSAR in addition, personnel from the Texas Department of Public Safety, the County Sheriff's Department, the Wallis Police and Volunteer Fire Departments could be called by the park attendants to assist in evacuating the public from the lake and park. After these areas have been cleared, the park attendants, being duly-appointed peace officers of the State, would be available to assist in the implementation of other of fsite protective measures. The protective measures for the public will include notification of affected individuals in the 10-mile EPZ. As described in Section 13.3.4.4, the County Sheriff's department will have the capability to notify and instruct the public of emergency conditions at ACNGS. Instructions may include the usage r of radioprotective drugs, seeking of shelter, such as remaining indoors with windows and doors closed, or, under severe conditions, evacuation. If evacuation is deemed necessary it will be carried out in accordance with detailed evacuation plans which will be contained in the Austin, Waller, Fort Bend, Colorado and Wharton County Emergency Operations Plans. These plans will include the identification of evacuation routes, traffic control points, relocation centers, mass care centers and the individuals and groups responsible for performing evacuation-related functions. A preliminary analysis has been conducted of the time which required to evacuate various, keyhole-shaped sectors within the ACNGS 10-mile plume exposure EPZ for transient and permanent populations. The analysis, provided in Appendix 13.3B, considered evacuation under a variety of circumstances. The analysis considered good and adverse weather conditions, transient populations, special facilities, such as schools and nursing homes, and projected populations. The study estimates a minimum evacuation time of 15 minutes was estimated for an area of about 2-miles in radius around the ACNGS, assuming good weather conditions and the permanent population. A =a x-imum evacuation time of 2 hours and 15 minutes was estimated in a 10-mile radius around the ACNGS, assuming heavy rain or foggy weather conditions and 8 the end-of-life permanent popula tion. The analysis demonstrated that there are no significant impediments to evacuation in the 10-mile area around the ACNGS. 55 Recommendations to the local governments regarding of fsite protective measures will be provided by the Texas Department of Health working closely with the ACNGS. The Texas Department of Health will perform independent evaluations of l radiological consequences, conduct environmental monitoring, and provide recommendations for offsite protective actions. As the lead State agency, the [ l Iexas Department of Health will also ensure the activation of appropriate member agencies of the State of Texas Disaster Emergency Services Council. 13.3.7.2.2 Protective Measures for the Ingestion Pathway Emergency Planning Zone i

The ingestion EPZ is an area about 50 miles in radius around the ACNGS. The l principal exposure ' source is from ingestion of contaminated water or food.

l ACNGS-PSAR Radiological releaves, prevailing meteorological data, and projected of fsite doses will be provided to the Texas Department of Health from ACNGS. This information will include, as applicable, estimated concentrations of radioactive material at various locations within the 50-mile ingestion Tschway EPZ. The Texas Department of Health, as the lead agency for protective measures in the ingestion pathway EPZ, will specify the appropriate protective measure, which may be based on ACNGS data, independent calculations and/or field sampling and analysis. These measures will include, as necessary, controlling drinking water supplies, impounding of milk, crops and other human or animal foodstuf fs, and establishing criteria for continuing consumption of these items. Implementation of protective measures within the 50-mile ingestion pathway EPZ will be carried out by the appropriate member agencies of the State of Texas Disaster Emergency Services Council and the responsible agencies, including agricultural agencies, within the affected counties. The counties, all or part of which are within the ACNGS 50-mile EPZ, are: Austin Brazoria Brazos Colorado Fayette Fort Bend Grimes 55 Harris Jackson Lavaca Matagorda Montgomery Waller Washington Wharton Tne communication links among the county sheriff departments will ensure i timely response to Texas Department of Health protective action recommendations. l 13.3.7.3 Recovery and Reentry Recovery operations will be carried out by the organization described in Section 13.3.2. Closely related to recovery is the reentry into damaged or contaminated areas of the plant or site. Recovery and reentry operations will be conducted in such a manner as to minimize exposure to workers and with total regard for the health and safety of the public. Plans for recovery and

reentry activities will be described in detail in the final ACNGS Emergency Plan.

[ 13.3.10.3 Public Education I HL&P will establish, in conjunction with Federal, State andL local' organizations, a program for the dissemination of informatica to the public in i i l 13.3-28 Am. No. 55, (1/81):

ACNGS-PSAR the plume exposure EPZ regarding how they will be notified and what their actions should be in the event of an emergency. This information will include, radiation, respiratory protection, sheltering, evacuation routes and the sources of additional information. HL&P will also establish a program to regularly acquaint news media personnel with emergency plans, radiation and sources of public information in an emergency. The programs and means of implementation will be desciibed in the final ACNGS Emergency Plan. 13.3.11 COMPAIIBILITY I In conjunction with the preparation of the foregoing preliminary plans for responding to emergencies and the attached preliminary evacuation analysis, HL&P has examined the compatibility of emergency plans with the Allens Creek site layout, site location and facility design features. No factors have been identified which would indicate that the Allens Creek project will be incompatible with emergency planning. With respect to access routes the preliminary evacuation analysis demonstrates that they are sufficient to carry out a timely evacuation of the population within the plume exposure EPZ. The population density and distribution in the site vicinity pose no problem with respect to carrying out a timely evacuation or other lesser emergency action. Similarly, land use and local jurisdictional boundarios do not present any unique or difficult problems for carrying out emergency response plans. Special facilities within the plume exposure EPZ have been identified, and these also pose no serious problems for emergency response planning. Finally, as Section 13.3.12 demonstrates, the ACNGS will satisfy the emergency planning standards of 10CFR50.47(b). 13.3.12 COHPLIANCE WITH 10CFR50 APPENDIX E PART II 10CFR50 Appendix E, Part II requires a description of the acans by which the standards of Part 50.47(b) will be met.

This letter is being sent in response to your letter dated Septenter 30 , 1980, regarding the participation of the Nuclear Regulatory Comission in the event of an emergency at the Allens Creek Nuclear Generating Station. The primary role of the NRC during a radiation emergency involving the potential or the unplanned release of radioactivity to the off-site environs is that of monitoring the licensees activities associated with the incident. The NRC will provide technical advice to the licensee if requested or required. The Federal Notice that you referenced in your letter defines the NRC's responsibility as the lead agency for emergency planning for federal and ~; local governments, which no longer applies. By Executive Order 12127 of March 1979 the President created the Federal Emergency Management Agency. The Presidents letter of December 7,1978 gave FEMA the lead agency role for the state and local emergency planning review and approval. For complete guidance as to the role of the NRC for incident response you l should review, Report to Congress: NRC Incident Response Plan NUREG-0728, and Criteria for Preparation and Evaluation of Radiological Emergency l Response Plans and Nuclear Power Plants NUREG-0654/ FEMA REP-1. If you have any questions or I rra/ be of further assistance please do not l hesitate to contact me. Sincerely, f g ; l a[

Dear Mr. Oprea:

In response to yotir letter of September 30, 1980, assurance is hereby given that the Department of Energy (DOE) will respond to requests for radiological assistance from licensees, federal, state and local agencies, private organi-zations or individuals involved in c; cognizant of an incident believed to involve source, by-product or special nuclear material as defined by the Atomic Energy Act of 1954, as amended, or other ionizing radiation sources. Assistance as indicated would be made available to the Allens Creek Nuclear Generating Station upon request and provided in consonance with response activities conducted by state, local and private industry preparedness personnel. Unless the DOE or a DOE contractor is responsible for the activity, ioniz-ing radiation source or radioactive material involved in an incident, the DOE radiological assistance will be limited to advice and emergency action essential for the control of the incediate hazards to health and safety. Radiological emergency assistance will be terminated as soon as the emer- , gency situatien is under control. Therefore, responsibility for postin- ! cident recovery, including further action for the protection of individuals and the public health and safety, should be assumed by the appropriate responsible federal, state or local government, or private authority as soon as the emergency conditions are stabilized. Requests for DOE emergency radiological assistance may be made on a twenty-four hour basis to the Joint Nuclear Accident Coordinating Center (JNACC), telephone: 505-844-4667. Sinc rely, 4 k R.

Dear Mr. McGuire:

The Texas Department of Health (TDH) hereby reaffirms its intention to provide radio Mgical emergency response and support for the Allens Creek Nuclear Generating Station. I The Texas Department of Health, Division of Occupational Health and l Radiation Control, Radiation Control Branch (RCB) is the governmental agency responsible for responding to radiological emergencies and fur l the development of final emergency procedures for the State, in l conjunction with the Disaster Emergency Services Division (DF.S) of the Department of Public Safety. The authority for the RCB is derived from the State of Texas Disaster Plan of 1980, Annex L, which was issued by the Disaster Emergency Services Council under the provisions of the Texas Disaster Act of 1975. 1 Prior to the initial fuel loading of the Allens Creek facility, the I RCB will work with Houston Lighting and Power Company, the DES and other state and local agencies to develop final site specific emer- ! gency procedures for the plume exposure zone (about 10 miles) and the ingestion pathway zone (about 50 miles) . 1 i l 13.3A-4 Am. No. 55, (1/81)

l Mr. W. F. McGuire, Manager July 1, 1980 Page 2 l It is the intention of the RCB that detailed emergency procedures will be developed and implemented for a wide range of emergency conditions classified according to their actual or potential severity. Emergency classifications and protective action criteria cor.sistent with those of Houston Lighting and Power Company and Federal and local agencies will be used. The RCB will participate in drills and exercises required at the Allens Creek faci *iity. The RCB and L35 are currently reviewing comnonications systems and methods to determine the most appropriate system for prompt notifica-tion to the RCB of any radiological emergency. A system will be operational and tested before the Allens Creek facility becomes operational. The Texas Department of Health looks forward to working with Houston Lighting and Power Company, other State agencies, and Federal and local agencies toward development of adequate emergency procedures for the Allen Creek Nuclear Generating Station. Yours truly,

Dear Mr. McCuistion:

This letter confitus discussions I have had with HL&P representatives concerning emergency planning by the Austin County Sheirff's Department in support of the Allens Creek Nuclear Generating Station. The Sheriff's Department is the primary organization for providing protection for the public in Austin County and will help to coordinate the emergency planning activities of local organizations within the county. We understood that detailed emergency planning is required to a distance of about ten miles from the nuclear plant. This area would encompass portions of Fort Bend, Waller, Wharton and Colorado Counties, as well as Austin County. We have discussed this matter with the Sheriff's Departments of these other counties and stand ready to coordinate emergency planning with them.. We understand that the primary State organization for radiological emergency planning is the Texas Department of Health and we look forward to working with them in further development of our emergency plans. The main center of emergency communications ;n the county is operated by the Austin County Sheriff's Department. Telephone, radio and teletype cocununica-tions systems are available to ensure that communications can be established to local agencies, surrounding counties and State emergency organizacirns. We understand that direct ec-c.unications will be provided between the Allens Creek station and the Austin County Sheriff's Deparment. We understand that the Allens Creek Emergency Plan will cover a wide range of emergency conditions classified according to their actual or potential severity. Our offsite emergency plan will relate to the same classifications as contained in the Allens Creek plan. We understand that the Texas Depart-ment of Health will also have those same emergency classifications. The emergency actions which we will implement will be cosusensurate with the emergency classification and will be based on reconumendations received from HLSP and/or the Texas Department of Health. The actions for which we will plan range from simple acknowledgment that we have been notified of an unusual event, up to and including evacuation _of the public. We vill cooperate with HLSP, local orgaisations and surrounding counties in the development of detailed evacuation planst 13.3A-6 km. No. 55, (1/81) l

l e We presently have the capability to :nake prompt notification to the population of Austin County in the event of an emergency. We understand that additional notification criteria are being evaluated. We will cooperate with HL&P in specific plans for public notification. We will participate in the radiological emergency training pro.ided by HL&P as well as emer rney drills and exercises that may be required. This Sheriff's Department stands ready to work with HL&P, the State of Texas and other response agencies in the development and implementation of our emergency plans relative to the Allens Creek facility, Very truly yours, s

1. INTRODUCTION l

In a letter dated December 26, 1979, the Nuclear l Regulatory Commission (NRC) issued a request for information regarding estimates of evacuation times for various areas around nuclear power plants. The NRC request was sent to all applicants for construction permits and licensees for plants under construction. Requirements for similar information are included in the NRC Final Regulations on Emergency Planning (Federal Register, 8/19/80) and NUREG-0654. The Final Regulations require that a CP applicant shall ...

                 " perform a preliminary analysis of the time required to evacuate various sectors and distances within the Plume Exposure Pathway EPZ for transient and permanent populations, noting major impediments to the evacuation or taking of protective actions."

The submission of evacuation data is being requested to provide useful evacuation planning data to local officials. The NRC also seeks suf ficient information to ensure the compatibility of proposed emergency plans with facility design features, site layout and site location, taking into account considerations such as population, access routes, land use and jurisdictional boundaries. One of the purposes of this report is to satisfy the Final Rule and NRC requests for information. The NRC request relates primarily to the actu11 evacuation f l time for both " normal" and " adverse" weathe,* conditions. In ( addition, NRC has requested ancillary information on four topics.

1) Total time to evacuate special facilities, such as I hospitals.
2) Time required to notify the population at risk.

l

3) Time required .for confirmation that evacuation has been completed.

Am. No. 55, (1/81)

4) Identification of alternative protective actions, such as sheltering, which may be implemented where "special evacuation problems" are identified.

As a response to this request, Houston Lighting & Power Company sponsored a study to calculate evacuation times associated with several evacuation scenarios. These calcula-tions were undertaken by HMM Associates, Inc. , of Waltham, Massachusetts. Tnese analyses were conducted using available f population data and a computer-based venicle traffic simulation model (see description of the NETSIM model in Appendix C) . The ancillary evacuation data were obtained from Allens Creek Project licensing documents and from interviews with local law enforcement officials. These included the Sherif fs of Austin County, Waller County, Cole 2do County, Fort Bend County, and' Wharton County. The County Sherif f of fices are the primary local agencies responsiole for emergency response. This report has been compiled to document the responses to the NRC requests. In subsequent sections, the report describes: o Population and Automobile Data Used for Evacuation Time Estimates (Section 2); o The Evacuation Network (Section 3); o Evacuation Model Areas, Cases and Scenarios (Section 4); o- Estimates of Evacuation Times (Section 5); o Ancillary Evacuation Data (Section 6); and o Conclusions (Section 7). Appendix 8 includes an explanation of the terminology and definitions used in this report. Am. No. 55, (1/81)

2. POPULATIO:4 AND AUTOMOBILE DATA USED FOR EVACUATION TIME ESTIMATES In order to estimate the evacuation times, several sets of population estimate data were required. The first set of population data identified was the 1990 permaner.t population within the 10-mile plume exposure emergency planning zone (EPZ). ,is included residents and non-essential workers at the ACNGd site. The second set was the peak 1990 population, defined as the total of permanent population, seasonal population, certain workers, public school students, and daily transients (recreational visitors). The third set of population data was the permanent population for the year 2020.

2.1 Sources of Data The data used for the various 1990 and 2020 population estimates come from HL&P's most recent population er,timates. A description of the data used in the preparation of this report is presented in Appendix A. 2.2 Data Derived for Use in Computer Model Analyses Three population cases were identified. Two 10-mile radius population distributions were derived from the best l I available 1990 population data. These were delineated for the 1990 permanent population and the 1990 peak population. The l tnird population distribution was the 2020 permanent population. The process used to derive these populations is described in Appendix A. l Am. No. - 55, (1/81)

ACNGS-PSAE It is assumed that evacuation of the area would be accomplished by automobile. In order to estimate evacuation times, the three sets of population data were converted to corresponding numbers of automobiles. It was assumed that permanent residents would evacuate with 2.5 people per automobile. Workers were assumed to occupy one person per automobile. These are conservative assumptions. Other population groups included in the peak population were handled on a case-by-case basis. The resultant roses displaying the numbers of automobiles to be evacuated from the EPZ are shown in Figures 2-1, 2-2, and 2-3 for the 1990 permanent, 1990 peak and 2020 permanent populations, respectively, i l i l i l Am.

3. EVACUATION NETWORK 3.1 Study Area One vital element in assessing the compatibility of proposed plans with facility design features, site layout and site location is consideration of access routes and jurisdictional boundaries. An evaluation was made of the road l system likely to be used by departing persons during an evacuation. Key roadways within a radius of 10 miles from the Allens Creek Project were examined. The 10-mile study area was selected to reflect the suggested size of tne NRC plume expo-sure emergency planning zone (EPZ). The 10-mile EPZ used as the study area is shown in Figure 3-1. The area includes portions of five counties. The closest concentration of population is Wallis, Texas. It is located four miles southeast of the plant. The Town of Sealy, Texas is located approximately eight miles north of the plant. The 10-mile EPZ comports with the NRC's emergency planning regulations which generally require protection from exposure to a radioactive plume released during a hypothetical accident out to a distance-of about 10 miles. There are no characteristics in the vicinity of ACNGS which would call for expanding or contracting the size of the plume exposure EPZ.

i Six sources of information were used in compiling descriptions of the evacuation network: 1) county road maps compiled by the State of Texas, 2) USGS Quadrangle maps, 3) Preliminary Safety Analysis Report (PSAR) and Environmental l Report (ER) for Allens Creek, 4) discussions with local law l enforcement officials, 5) Flood Prone Area maps developed by the National Flood Insurance Program, and 6) datr.-from a 10-mile area field survey conducted by HMM in February 1980. These sources of information provided data suitable for calculating times for evacuation of areas within the 10-mile . EPZ through use of a computer model for simulation of various vehicle evacuation scenarios. Am. No. 55,(1/81)

IGURE 3 lO-MILE RADIUS STUDY AREA Am. No. 55 (1/81)

l ACNGS-PSAR For all time estimates, HMM used the road network as it exists in 1980. This was done because the exact conformation of the road network in future years (1990 and 2020) is unknown at this time. This results in a conservative assumption, since it l's probable that occasional road network improvements will be made during the next 10 to 40 years. 3.2 Network Definition for Use in the Computer Model The system of access rointes considered in the evacuation modeling consists of major streets and intersections witnin the 10-mile EPZ. The major streets included roadways of the following classifications.

1) Arterial Streets are enaracterized by continuity of travel. They connect business, population, or major recreation areas. They are characterized by traffic controls and geometric designs wnich ennance traffic flow and safety. In the vicinity of Allens Creek, these are generally heavy duty two lane roads capaole of carrying significant traffic at high speed.
2) Connector Streets are links between business or residential areas (served by local roads) and arterial streets.

Most vehicles enter the evacuation network via the smaller local residential and business roadways. Because these local roads are " upstream" of the major streets which make up the I evacuaticq network, the movement of traffic on these smaller roads was r.9t evaluated as part of the computer model l simulation. The methodology used for movement of autos onto the network is discussed in Section 4.4. In addition to the major roadways, the evacuation network' included the intersections of major streets. The intersections l are particularly important, since the ability of intersections to handle traf fic.can be the major capacity constraint during an evacuation. Am. No. 55, (1/81) l L

  .' l ACNGS-PSAR The network of major streets and intersections considered in the evacuation analysis is shown in Figure 3-2. Figure 3-2 also indicates traffic flow likely to be used during evacuations.

Major roads wnich would service the Allens Creek EPZ during an evacuation would include: Route 36, wnien lies'in an approximate north to southeast direction, connecting the ACNGS site to Sealy and wallis; Interstate Hignway 10 leading east and west from Sealy; Route 1093 radiating east and west from Wallis; anc Routes 36 rnd 60 heading southeast and south from Wallis. Table 3-1 is a list identifying the access routes in the network. For the purposes of calculating evacuation times, this evacuation network was computer coded into a system of " nodes" and " links". The nodes correspond to network intersections, and the links correspond to *.ne individual roadway segments between the nodes. Figure 3-3 is a diagram of the types of nodes and links discussed in tne following sections. 3.3 Internal Links and Nodes A total of 99 internal links,. representing actual road cagments, are included in the network. A total of 75 internal-nodes, representing actual and representative intersections within the model, were included in the network. Representative nodes were required in the evacuation simulation in two instances: wnere a number of local roads -join the model's network, and in cases where it was deemed desirable to measure traffic flow past a certain point. Tne internal nodes and links used in the Allens Creek road network are shown in Figure 3-Aa. 3.4 Entry and Exit Nodes and Links Entry links and nodes were the mecnanisms used in the computer model to move automobiles onto the network for

       . evacuation. For modeling purposes, the estimated number of automobiles (identified in Section 2.2) were assumed to enter tne network at entry nodes. Entry nodes were used as surrogates for all the parking lots, driveways, smaller streets, etc., from anien the evacuating automoniles originate.

From tne entry nodes, the cars were simulated to travel along the 35 entry links where they entered the internal network, on a stochastic basis, at appropriate internal nodes. Tne venicles were advanced through subsequent internal nodes on the basis o f precetermined turning movements. Tne travel speed of venicles was determined by the simulation model according to the amount of traf fic carried by links and nodes. Maximum speed of veni-cles was controlled by operators of the model. Once carried through t,1e internal network by tne simulation process, the venicles were simulated to leave the internal network at the exit nodes. Exit nodes were designated nodes lying outside tne area being evacuated. For example, for the full 10-mile radius evacuation, exit nodes were placed on major streets beyond the radius of the 10-mile study area and by the entrances to Inter-state Route 10. For the full 10-mile radius evacuation, tne internal links and nodes and the entry and exit nodes are snown in Figure 3-Aa and 3-Ab. The time required to evacuate a given area was the time required for all traf fic to pass by the exit nodea designated for that area. 3.5 Initialization Process For purposes of conservatism, a vehicle loading initiali-zation process was employed. Thit: involvud placing a certain amount of background traf fic on the roFJ network prior to the ! start of the evacuation process. This group of automobiles was distinct from the automobiles identified in Section 2.2 (resi-dents, students, workers, etc.). Thus, the evacuation time estimates ultimately developed were based on evacuation of both background _ traffic and the subject population-groups for the years 1990 and 2020. Initialization involved approxicately 700' I automobiles for scenarios involving 'the permanent population and 1400 auto nobiles for scenarios involving tne peak population. Am.

ACNGS-PSAR 4 EVACUATION MODEL AREAS, CASES AND SCENARIOS The NRC letter of December 26, 1979 indicates a need for evacuation time estimates for several scenarios. The following excerpt from the letter outlines the data requirements of NRC: The areas for wnich evacuation estimates are required must encompass the entire area within a circle of about 10 miles radius, and have outer boundaries cor-responding to the plume exposure E07 These areas are as follows: Distance Area 2 miles two 180 0 sectors 7 miles four 90 sectors about 10 miles f;ar 90 sectors Estimates for the outer sectors should assume that the inner adjacent sectors are being evacuated simul-taneously. To the extent practical, the sector boundaries should not divide densely populated areas... Two estimates are requested in each of the areas defined in item 1 for a general evacuation of the~ population (not including special facilities). A best estimate is required and an adverse wratner estimate is required for movement of the population. The Final Rule on emergency planning includes more general language, but it appears to require approximately the same thing. To respond to the NRC requests, HMM defined a series of areas, cases and scenarios. Areas were defined as geographic areas. Cases were assumed combinations of weather and popula-tion conditions. Time-estimates were-developed for scenarios, and each scenario was made up of one case and one or .more areas. 4.1 Areas Eleven geographic areas were identified for the evacuation

time analysis. These were identified on the -basis of

( meteorological and jurisdictional considerations. On the basis Am. No. 55, (1/81) -

r ACNGS-PSAR of meteorological considerations, four quadrants of approximately 90 degrees centered at the site were identified. On the basis of jurisdictional and geograpnical considerations, conspicuous natural and man-made boundaries were cnosen for these quaorants wnien coulo be readily identified by residents and gsvernment o f ficials. The principal coundaries identified were county boundaries and Rt. 36. Three radial lines connecting the plant and three tri-county intersections were also used. The outer bounoaries o f the eleven areas are primarily defined by circles having radii of 2-miles, 5-miles and 10-miles. None of tne eleven areas overlap. See Figure 4-1. Area 1 includes all land within 2 miles of the plant plus all area included in the lake and tne two parks. Inis area corresponds approximately to the 2-mile radius area of interest to the NRC. This area was not divided into two sectors of 180 U each, because it consists largely of site and park-property. Areas 2, 3, 4 and 5 correspond approximately to 90 0 quadrants located from 2 to 5 miles from the plant. Area 2 lies approximately southwest of the plant between the 2-mile and 5-mile circles. Specifically, it is bounded cy: the 2-mile circle on the northeast; on the northwest by a radial between the plant and tne intersection point of Austin, Colorado and Wharton Counties; on the southwest by the 5-mile circle; and by a radial line between the plant and boundaries of Austin, Fort Bend and Wnarton Counties. Area 2 might be evacuated in the event of a northeast wind. Area 3 lies southeast of the plant. It is bounded by: l the 2-mile circle and the site on the west; on the soutnwest by l the radial from the plant to the intersection point of Austin, Fort Bend and wharton Counties; the 5-mile circle on the southeast; and the radial from the plant to the intersection-point of Austin, Fort Bend,-and Waller Counties. Area 3 mignt l De evacuated in the event of a northwest wind. Area 4 lies northeast of the site. It is bounded by: tne

2-mile circle on the southwest; on the southeast by the radial from the plant to the intersection point of Austin, Fort Bend,

AQCS-PSAR Area 10 lies northwest of the site. It is bounded by: the 5-mile circle and Route 36 on the east; Interstate 10 and Little Bernard Creek on the north; the 10-mile circle on the west; and the Austin-Colorado County line on tne soutn. Area 10 might be evacuated in the event of a southeast wind. Area 11 lies west of the site. It incluoes all portions o f Colorado County within 10 miles of the plant. It might be ! evacuated in the event of an east wind. 4.2 Cases Cases were defined according to population and weather conditions. Four base cases were analyzed. In c der to identify a range of times for evacuation, estimates were developed for a "best estimate" case as well as several conservative cases. Case A involved evacuation of tne 1990 permanent population via the 1980 road network during good weatner. This was intended to correspond to the NRC request for a "best estimate". Since population roses developed in the most recent HL&P population estimates locate persons in their residences, the evacuating population.was assumed to originate from residences. Since most people spend more time at home than any i other specific place, it is reasonable to evaluate at least one case in which an evacuation is initiated while people are at i home, with all schools and workplaces closed. The permanent population was also assumed to include 100 non-essential workers at the Allens Creek site, which will operate 24 hours per day. Good weather was defined to be clear weather, day or night, with no fog, precipitation, or other weather conditions j to limit vehicle speed or visibility. Target speeds used were posted speed limits, with occasional variations depending on l l road design or capacity. l l Am. No. 55, (1/81)

 . -                              ACNGS-PSAR Case a was intended to be a very conservative estimate, as compared to the Case A best estimate. Case B was based on evacuation of 1990 peak population via the 1980 road network during adverse weather. The peak population for Case B was defined to include the total of the following:

o permanent population included in Case A (i.e., assume all residents are at home); o senool popu]ncion (i.e., assume all schools are full); o seasonal population (i.e., assume all seasonal resort homes are occupied); o recreational population (i.e, assume the typical peak number of recreational visitors is in the EPZ); and a certain occupational groups (i.e., assume tnat all teachers are at scnool, and tnat 400 extra workers are at Allens Creek for a refueling). Note that the peak population above is overly Conservative. For example, it has been assumed that all residents, .some of whom are students and workers, are in their homes. Meanwhile, it has also been assumed that all students are at school and certain workers are at work. Obviously, they cannot be.in two olaces at the same_ time. This is double counting, and it generally leads to overly conservative results (i.e.,' overly long time estimates). Adverse weather was defined as bad

      *eatner, not worst possiole weatner. Specifically, adverse weather was defined as a severe storm or fog, summer or winter, wnicn would suostantially reduce visiollity and driving.

ACNGS-PSAR speeds. Travel speeds for adverse weatner were targeted at approximately one-half of posted s,'ed limits, with occasional variations depending on the road design and capacity. Adverse weatner conditions could occur during a time of peak population. Case C is similar to Case A. Case C involved evacuation o f tne year 2020 permanent population during good weather via the 1980 road network. This is a conservative case. It assumes that 40 years of population growtn will occur with no accompanying exoansion of tne capacity of tne road system. In fact, it is unlikely tnat tne road system would not ce upgraded during forty years of population growtn. Examination of Case C is useful as a test of tne sensitivity of evacuation times to increases in population. Case D is more conservative than Case C. It involved using tne 1980 road system to evacuate tne year 2020 permanent population during adverse weather. Cases C and 0 snould provide some indication of tne sensitivity of evacuation times to adverse weatner. Case C and Case O cid not attempt to evaluate evacuation of the peak 2020 population. It was felt that development of a year 2020 peak population estimate analogous to tne 2020 permanent pooulation would not be-meaningful at tnis time. 4.3 Scenarios A scenario was defined as the evacuation of a specified population, during specified weatner conditions, from a specified area _ or group of areas. inus, scenarios include one case and one or more areas. Most scenarios involve more than one area because inner adjacent areas are also included in estimates. Evacuation time estimates nave been developed for-AS scenarios. Eacn of tne areas either individually or in comoinations were evaluated according to Cases A, B, C, and D. In Table 4-1, Roman numerals' nave been used to denote the

ACNGS-PSAR venicle estimates for eacn of tne eleven geograonic areas were included in the simulation model. This wa accomplisned by a ssigning automobiles, shown in Figures 2-1, 2-2, and 2-3, on a sector-by-sector basis, to designated entry nodes. In general, venicles oricinating in a sector were assigned to one or more of the entry nodes closest by road to that particular sector. Loading of tne network witn venicles was initiated simultaneously at each entry node witnin the model area to be evacuated. Inis means tnat eacn car to be evacuated was out into a queue, or line, at the appropriate entry node. Asi. No. 55, (1/81)

5. ESTIMATES OF EVACUATION TIMES The results of the evacuation time calculations by HMM are summarized in Table 5-1. The table outlines the applicable evacuation times for each of the scenarios suggested by NRC, as well as several other scenarios of interest. These estimates represent tne elapsed time from notification of the public to the time when all autos have left the area. As such, tney represent maximum values of evacuation time for eacn scenario.

Use of dif ferent population and weather conditions is intended to provide a range of values for evacuation times, witn Cases A and B intended to Oracket tne range for 1990 scenarios. Tnus, the maximum time for an evacuation during average conditions of population and weather would fall between tne estimates for Case A and Case B. Four scenarios were examined for Area 1. It was determined that Area 1, the 2-mile radius area, could be evacuated in 15 minutes during good weather (Scenario IA). This time estimate included evacuation of 100 non-essential plant workers and any residents within two miles. For Scenario IB, the peak population, adverse weather case, evacuation time was estimated to De 70 minutes. With the exception of the 102 automobiles assigneo to tne small recreation area in Scenario IB, all ACNGS and park traffic was assumed to leave the site using only one exit, the proposed bridge over Route 36. Time estimates for Scenarios IA, IS, IC, and ID are shown in Taole 5-1. For the 5-mile radius area, Scenarios II tnrough VI are relevant. As indicated in Table 4-1, estimates were made for each of the four 2-5 mile areas plus the inner adjacent 2-mile area. Evacuation time estimates were also made for the entire 5 mile area (Scenarios VI A, B,C, and 0) . Thus, in connection with the 5-mile radius, a total of 20 evacuation scenarios were examined. The shortest evacuation time, 30 minutes, was associated witn Scenarios IIA, IVA and VA. Tne longest evacuation time for the 5-mile area was associated with the 2020 permanent population during adverse weather (Scenario VIO). Am. No. 55, (1/81)

l ACNGS-PSAR In connection witn the 10-mile radius, 24 evacuation scenarios were examined. As indicated in Taole 4-1, these include Scenarios VII, VIII, IX, X, XI, and XII witn Cases A, 8, C, and O. The shortest evacuation time, 40 minutes, was associated with Scenario VIIIA. The longest evacuation time for the 10-mile area was associated with Scenario XIIO. It should be noted that during most of the year, the size of the oopulation at risk is closer to the permanent population than the peak population condition. Also, adverse weatner occurs only a minority of tne time. It can, tnerefore, be in ferred *..la t the most probable maximum evacuation times for 1990 will De closer to those for Case A than Case 8. Tne calculations nave intentionally incorporated many conservative assumptions which teno to increase estimates of evacuation times. A few examples are as follows:

1) Douole counting of some population groups, as discussed in Section 4.2, leads to conservative estimates for Case B.
2) The initial; ation process places approximately 700 cars on the road prior to the ceginning of evacuation for Cases A, C and D. Approximately 1400 cars are involved in initialization for Case B.

Tnis assumption is probably conservative, especially for periods late at night when Dackground traffic would be minimal.

3) It is assumed tnat all stop signs, traffic lights and traffic control measures would be obeyed. It is assumed that local officials do nothing to expedita traffic movement.
4) The evacuation analysis considered only one exit from the ACNGS site and park areas, the proposed bridge over Route 36. Had grade level emergency and service road exits also been used, evacuation times would nave been significantly; reduced for Case B.

6. ANCILLARY EVACUATION DATA In response to the NRC request, several ancillary evacua-tion topics nave been discussed with tne Snerif f of Austin County. Tne following subsections document the conclusions of those discussions.

6.1 Soecial Facilities inere are a total of eignt facilities which qualify as "special facilities" for evacuation purposes. Detailed plans for evacuation of these facilities will be included in the FSAR. Estimates of evacuation times would require the use of sucn plans. The analysis by HMM assumed that all persons from special facilities would be evacuated simultaneously with tne general population. As of now, tne following information has been developed and used in the HMM analysis.

1) Allens Creek site recreation areas, located along State Highway 36 and FM 1458 cetween two to four r miles from the site in a soutneasterly direction, nave provision for 2,100 visitors (ref. ACNGS-ER Supplement and subsequent information from HL&P).

For purposes of the evacuation analysis, it was assumed that one car for eacn of tne 519 parking spaces at the two recreation areas would be involved in-tne. evacuation. I I

For purposes of the HMM analysis, it was assumed that evacuation would require 140 cars, with respect to special facilities, no major impediments to the evacuation or taking of protective actions was identified by HMM during the study. 6.2 Notification and Confirmation Times Notification of the population to take some emergency action is an important element of emergency plans. In a real emergency, notification would take many forms. For example, radio, television, cable TV, telephone and word of mouth would all play a part in spreading the ilert. However, for purposes of planning for nuclear emergencies, it is necessary to identify a primary method of notification. This must be some method of notification wnich is under government control and which is specifically intended to reach virtually every member of the population at risk. It must be available 24 hours per day. Effective methods to rapidly notify the public within this area in the event of an emergency have long ceen established. The final ACNGS Emergency Plan will describe the specific methods wnich will be utilized to ensure that the capacility exists to notify the public in the 10-mile EPZ within 15 minutes of notification to of f-site authorities. If necessary, additional notification systems will be installed. Another important element of emergency planning is confirmation. Tnis is a process by which officials confirm that all people have evacuated the area. Several methods are l possible. At this time, it is assumed that the confirmation process would be accompli 1ned cy law enforcement vehicles traveling house-to-house. Confirmation times are included in Table 6-1. These estimates were developed on the basis of Am. No. 55, (1/81)

ACNGS-PSAR It should be noted that in a real evacuation, the total time for notification, evacuation and confirmation steps is not equal to the sum of the estimates for eacn of the three steps. This is because the processes of notification, evacuation, and confirmation would overlap significantly. In many cases, evacuation of the population would begin before notification was complete. Confirmation would also begin oefore the evacuation was completed. Therefore, the total time to carry out the process of notifying the population, implementing an evacuation, and confirming the evacuation would be less than the total of the times estimated for each step alone. I 6.3 Soecial Evacuatio.1 Problems Past evacuations during emergencies were discussed with the Snerif f of Austin County. He indicated that no insurmountacle problems have been encountered. Sealy was once placed on alert during an accidental gas line shut-of f. Notification took only 20 minutes. Police and fire personnel were used. Officials from other counties commented that there would be no special evacuation problems in their areas. l Am. No. 55, (1/81)

SUMMARY

AND CONCLUSIONS Pursuant to NRC's Final Rule on Emergency Planning, and in response to a request contained in a 12/26/80 letter from NRC, an analysis of evacuation times was conducted for the 10-mile radius Emergency Planning Zone around Allens Creek Nuclear Generating Station. Input information was derived from ACNGS licensing documents, from field inspections, from local officials and from other sources. A computer model method was used to simulate several evacuation scenarios. For each scenario an estimate of time to conduct evacuation was developed. The analysis included evacuation of population in various sectors at various distances witnin the plume exposure Emergency Planning Zone. The analysis included evacuation of permanent and transient populations. Various weather conditions were considered. The analysis considered site layout and location with respect to access routes, surrounding population distributions, land use and local jurisdictional boundaries. Throughout the analysis, ef forts were made to identify major impediments to evacuation or taking of protective action. A total of forty eight time estimates were developed in consideration of various weatner conditions, population groupings and geographical areas. These estimates are shown in Table 5-1. The range of values corresponds to a range of assumptions regarding population and weather. For the site and all areas within 2 miles of the plant, evacuation of the 1990 l permanent population during good weather'would be completed within 15 minutes, while evacuation of the peak population during adverse weather would be completed within 70 minutes. For the 5-mile radius portion of the EPZ, evacuation of the permanent population during good weather would oe completed within 65 minutes, while evacuation of the peak population during adverse weather would be completed within 80 minutes. For the 10-mile radius EPZ, evacuation of the permanent population during good weather would be competed within i Am. No. 55, (1/81)

APPENDIX A POPULATION AND AUTOMOBILE DATA USED FOR CLEAR TIME ESTIMATES The number and location of 1990 permanent, 1990 peak, and 2020 permanent population data for the area witnin a 10-mile radius of Allens Creek Nuclear Generating Station were obtained from HL&P's most recent population estimates. Additional information was obtained from HL&P. Permanent population estimates for 1990 and 2020 we
e furtner disaggregated fo r sectors between five and ten miles. Also included in evacuation of the permanent population were 100 non-essential plant workers at ACNGS. Peak population estimater for 1990 include the permanent population, 400 refueling workers at tne plant, a full compliment of recreational visitors at parks adjacent to the site, recreational visitors at other parks within ten miles of ACNGS, students and faculties at schools, seasonal residents and persons at medical facilities. Special facilities are discussed in Section 6.1.

The associated number of automobiles for 1990 permanent, 1990 peak and 2020 permanent populations are shown in Figures 2-1, 2-2, and 2-3. Average venicle occupancy rates used for the study included: 2.5 persons per car for permanent population, 1.0 persons per car for workers, 3.0 persons per car for general recreational population, and approximately 4.0 persons per car for the parks adjacent to the site. Buses were estimated to carry 30 school children. A-1 Am. No. 55, (1/at)

i M2CS-PSMR ine NETSIM Model NETSIM is a traffic netnorx simulation mocel. It was originally designea for tne traffic engineer to evaluate alternative network control and traffic management strategies for improving urban traf fic flow. NETSIM was developed for the Feceral Hignway Administration (FHWA) by the consulting firms of Peat, Marwick & Mitchell and General Applied Science Lacoratory (GASL). NETSIM nas been valtaated enrough an extensive program of field testing and witn fielo cata collected in the Washington, DC area. Further validation was ootainec by test programs in San Jose, California, as well as in New Jersey. Tne mocel uses microscopic inspection. This means tnat NETSIM uses a detailed representation of the road network, following individual venicles, and updating tneir status and position in short-term intervals. Tne road network representation includes: tne link geometry (i.e., right-turn, thru, left-turn or diagonal), link length, numoer of moving lanes, grace, intersection signalization, and entry and exit points. The model emits venicles onto tne network at entry points and follows.each venicle individually as it travels along tne network until it reacnes an exit noce. At this point, tne vehicle is taken of f tne network and statistics upaated. The NETSIM model follows vehicles.by comouting the location and status of eacn vehicle every second. NETSIM simulates venicle cenavior by calculating speed and status using car following, queueing _benavior, lane enange, venicle neacways, and acceptacle lag for lane changes. These distributions were empirically derived by the validation stuales. To keep track of network performance, tne madei uodates statistics on the full network ana on eacn link at the end of each time step (one secona). .NETSIM calculates cumulative statistics for the entire network and for eacn link'at tne ena

of each subinterval, and wnenever requested. It also keeos a running total of instantaneous link-oerformance statistics wnich can be reported at any time during the simulation. Tne NETSIM mocel requires very cetailed and extensive data-inputs. There are two basic types of inputs: network data (or exogenous) and embedded data. Tne network data is mandatory and includes line geometry, intersection signalization, link turning movements, link ooeration, entry link volume, anc tne time of simulation. Link geometry inputs include: link-tengtn, tvoe of turn and receiving noce, and grace of tne link. Link operation inputs include: number of moving lanes, target speed, neadway, ana lane enannelization. Link turning movements include: percent of venicles turning to each destination. Tne intersection signalization inputs are tne types of control wnicn include sign, fixec time signal, or actuated

         -signat. The entry link volume inputs include tne flow rate anc percent trucks. The length of sumintervals and the total simulation can be selected.

Tne emcecded cata inouts include the calibration _ data which are embeddea in the model algorithms. These data inputs are optional and the model uses- default values if they are not specified. These inputs can change the distribution for-acceptacle gap for turning venicles, venicle soeed, neadways, and amber phase response. The acceptable lag for lane change and mean' effective venicle lengths can also be' changed with embecced inputs. The NETSIM model recorts on system performance cy cisplaying cumulative and instantaneous statistics for both the full network and inoiviaual links. 'The cumulative statistics incluce: occupancy, number _of venicles discharged, queue lengtn,-delay time, average speed ano signal code. _Tne time is ' also reported for any' statistical output. These statistics provide tne information neeced.to determine wnen tne network is cleared and the effectiveness of tne traf fic contro1 ' strategies. _ '.C - 2 Am. No. 55. (1/81) L}}
