The NRC issues regulatory guides to describe and make available to the public methods that the NRC staff considers acceptable for use in implementing specific parts of the agency

=s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in reviewing applications for permits and licenses. Regulatory guides are not substitutes for regulations, and compliance with them is not required. Methods and solutions that differ from those set forth in regulatory guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.

This guide was issued after consideration of comments received from the public.

Regulatory guides are issued in 10 broad divisions C1, Power Reactors; 2, Research and Test Reactors; 3, Fuels and Materials Facilities; 4, Environmental and Siting; 5, Materials and Plant Protection; 6, Products; 7, Transportation; 8, Occupational Hea lth; 9, Antitrust and Financial Review; and 10, General.

April 2011 Revision 1 REGULATORY GUIDE

OFFICE OF NUCLEAR REGULATORY RESEARCH

REGULATORY GUIDE 3.67 (Draft was issued as DG-3039, dated May 2010) STANDARD FORMAT AND CONTENT FOR EMERGENCY PLANS FOR FUEL CYCLE AND MATERIALS FACILITIES

A. INTRODUCTION

This regulatory guide provides guidance acceptable to the U.S. Nuclear Regulatory Commission (NRC) staff on the information to be included in emergency plans and establishes a format for presenting the information. Use of a standard format will help ensure uniformity and completeness in the preparation of emergency plans. The NRC's regulations in 10 CFR Part 30, "Rules of General Applicability to Domestic Licensing of Byproduct Material" (Ref.1); Part 40, "Domestic Licensing of Source Material" (Ref. 2); Part 63, "Disposal of High-Level Radioactive Wastes in a Geologic Repository at Yucca Mountain, Nevada" (Ref. 3); Part 70, "Domestic Licensing of Special Nuclear Material" (Ref. 4); Part 72, "Licensing Requirements for the Independent Storage of Spent Nuclear Fuel, High-Level Radioactive Waste, and Reactor-Related Greater Than Class C Waste" (Ref. 5); and Part 76, "Certification of Gaseous Diffusion Plants," (Ref. 6) require some fuel cycle and materials licensees to prepare emergency plans. The information specified in this guide should be included in the licensee's emergency plan to comply with the requirements of 10 CFR 30.32(i)(3), 40.31(j)(3), 63.161, 70.22(i)(3), 72.32, and 76.91. An acceptable emergency plan should describe the licensed activities, the facility, and the types of accidents that might occur. It should provide information on classifying postulated accidents and the licensee's procedures for notifying and coordinating with offsite authorities. The plan should provide Rev. 1 of RG 3.67, Page 2 measures that might be necessary, the equipment and facilities available to respond to an emergency, and how the licensee will maintain emergency preparedness capability. It should describe the records and reports that will be maintained. There should also be a section on recovery after an accident, including plans for restoring the facility to a safe condition. Detailed descriptive information on processes, materials storage areas and containers, ventilation, process controls, activity locations, vessels, and confinement of radioactive or other hazardous materials may be necessary for NRC to evaluate the adequacy of the emergency plan. Detailed information that would help response organizations assess accident consequences and estimate releases should be included in the plan. Other detailed information that is needed primarily for the licensing review may be submitted separately as a supplement to the plan or incorporated by reference to other licensing submittals. Regulatory Guide 3.67, Revision 0 superseded the guidance in Revision 1 of NUREG-0762, "Standard Format and Content for Emergency Plans for Fuel-Cycle and Materials Facilities" (Ref. 7). Preparing plans in accordance with this revision of Regulatory Guide 3.67 will facilitate NRC review and approval of applications made pursuant to 10 CFR 30.32, 40.31, 63.21, 70.22, 72.24, and 76.35. An effective response to an emergency comprises WHAT is to be done (procedures), BY WHOM (response personnel), and WITH WHAT (equipment in designated locations). The emergency plan reflects, in general terms, the preplanning done in preparing to cope with an emergency, but the details of the actual response are typically contained in the emergency plan's implementing procedures. The implementing procedures are the heart of the emergency response. They must be clear, precise, and easily understood. Each procedure should pertain to a narrow, specific response action. Throughout this guide, the licensee or applicant will be asked to describe procedures instead of submitting them to NRC for approval. NRC uses this practice to eliminate the need for a license amendment every time the procedures need to be changed. Details contained in the procedures will need to be changed from time to time. If each change in a procedure required NRC approval, frequent and time-consuming license amendments would be required. Therefore, the license is issued on the basis of the descriptions of procedures in the emergency plan. The procedures may be changed within the scope of these descriptions. However, this practice makes it necessary for the licensee or applicant to give close attention to the way the implementing procedures are described. In preparing the implementing procedures, the applicant should be aware that NRC may review them during the licensing process and during inspections, to ensure that the procedures are current and workable and that they conform with the descriptions in the emergency plan. Any changes to the emergency plan that decrease the effectiveness of the plan must have NRC approval before implementation, pursuant to 10 CFR 30.34(f), 40.35(f), 63.44(b), 70.32(i), 72.44(f) and 76.91(o). The licensee may change the emergency plan without prior NRC approval if the changes do not decrease the effectiveness of the plan. These changes should be submitted to the appropriate NRC licensing office and to affected offsite response organizations within 6 months after the changes are made. The submittals should include the date the changes became effective. Guidance on the process for making emergency plan changes is provided in Regulatory Issue Summary (RIS) 2005-02 (Ref. 8). A

copy of the RIS is available at http://www.nrc.gov/reading-rm/doc-collections/gen-comm/. The licensee is encouraged to have a single emergency plan to meet the requirements of State agencies or the Community Right-To-Know Act, as well as to comply with the regulations of NRC. Additional material to meet these other regulations should either be included in the plan or referenced in Rev. 1 of RG 3.67, Page 3 the licensee's emergency plan submitted to NRC. This additional material will be reviewed by NRC only to ensure that it does not diminish compliance with NRC's requirements. Finally, the licensee should certify that it is in compliance with Title III of the Superfund Amendments and Reauthorization Act of 1986, Pub. L.99-499, entitled "Emergency Planning and Community Right-to-Know Act of 1986," with respect to any hazardous materials possessed at the plant site. Any information collection activities mentioned in this regulatory guide are contained as requirements in 10 CFR Parts 30, 40, 63, 70, 72, and 76, which provide the regulatory basis for this guide. The information collection requirements in these regulations have been cleared under Office of Management and Budget (OMB) Clearance Nos. 3150-0017, 3150-0020, 3150-0199, 3150-0009, and 3150-0132 respectively except for Part 76. Part 76 does not have an OMB clearance number since less than 10 facilities would be subject to it. The NRC has determined that this Regulatory Guide is not a major rule as designated by the Congressional Review Act and has verified this determination with the OMB. B. FORMAT Emergency plans may be submitted to NRC in paper form, or electronically, pursuant to 10 CFR 30.6, 40.5, 63.4, 70.5, 72.4, and 76.5. Guidance for making electronic submittals is available at http://www.nrc.gov/site-help/e-submittals.html. Marking and Control of Sensitive Information After the terrorist attacks on September 11, 2001, NRC found it necessary to be more judicious in releasing information that could be useful to an adversary planning an attack. Guidance on the marking and control of such information is provided in RIS 2005-31, "Control of Security-Related Sensitive Unclassified of Non-Safeguards Information Handled by Individuals Firms, and Entities Subject to NRC Regulation of the Use of Source, Byproduct, and Special Nuclear Material " (Ref. 9). A copy of the RIS is available at http://www.nrc.gov/reading-rm/doc-collections/gen-comm/. Detailed information concerning the detection and response to an emergency could be useful to an adversary. Therefore, emergency plans should be marked as security-related information to be withheld under 10 CFR 2.390. Each applicant should note that a general description of the emergency preparedness program which can be released to the public may be required to establish a public record of how the applicant complies with the regulations discussed in this guide. Graphical Presentations Graphical presentations such as drawings, maps, diagrams, sketches, and tables should be employed if the information may be presented more accurately or conveniently by such means. Due concern should be taken to ensure that all information presented is legible, that symbols are defined, and that scales are not reduced to the extent that visual aids are necessary to interpret pertinent items of information. These graphical presentations should be located in the section where they are primarily discussed. References used may appear as footnotes to the page where discussed, or at the end of each chapter.

Rev. 1 of RG 3.67, Page 5 C. EMERGENCY PLANS

1. FACILITY DESCRIPTION The information in this section is to provide perspective about the facility and the licensed activity such that the adequacy and appropriateness of the licensee's emergency planning, emergency organization, and emergency equipment can be evaluated.

1.1 Description of Licensed Activity Present briefly the principal aspects of the overall licensed activity. A general description of licensed and other activities conducted at the facility, the location of the facility, and the type, form, and quantities of radioactive and other hazardous materials normally present should be included. Any radioactive materials authorized under a State license should also be described.

1.2 Description of Facility and Site Provide a detailed drawing of the site for the emergency plan. The detailed drawing should be drawn to scale and show or indicate the following:

1. Onsite and near-site structures with building numbers (if applicable) and descriptive labels.

2. A bar scale in both meters and feet.

3. A compass indicating north.

4. Roads and parking lots onsite and main roads and highways near the site.

5. Site boundaries, showing fences and gates.

6. Exhaust stacks, storage areas, retention ponds, and other major site features.

7. Rivers, lakes, streams, or other ground-water sources onsite and within approximately (1 mile). Provide a concise description of all site features affecting emergency response, including communication and assessment centers, assembly and relocation areas, and process and storage areas.

Identify any additional site features likely to be of interest because they are related to the safety of site operations. The emergency plan should include a list of hazardous chemicals used at the site, typical quantities possessed, locations of use and storage, and the hazardous characteristics (radioactivity, pH, other) of material in sediment and retention ponds. The list may be limited to larger quantities likely to impact emergency response efforts (i.e., bulk storage containers, etc.). The stack heights, typical stack flow rates, and the efficiencies of any emission control devices should be summarized in the emergency plan to help response organizations assess releases.

1.3 Description of Area Near the Site Include a description of the principal characteristics of the area near the site at which licensed activities are conducted. Indicate the site on a general-area map [approximately (10-mile) radius] and on a United States Geological Survey (7.5 minute) topographic map

1 [approximately (1-mile) radius]. Provide a map or aerial photograph indicating onsite structures and near-site structures [about (1-mile)

radius]. On this photograph or map, include the following:

1. Locations of population centers (towns, cities, office buildings, factories, schools, arenas, stadiums, etc.);

1 Topographic maps can be obtained from the U.S. Geological Survey, Map Distribution, Denver Federal Center, P.O. Box 25286, Denver, CO 80225. The telephone number is (303) 236-7477.

Rev. 1 of RG 3.67, Page 6

2. Locations of facilities that could present potential protective action problems (schools, arenas, stadiums, prisons, nursing homes, hospitals);

3. Identification of primary routes for access of emergency equipment or for evacuation, as well as potential impediments to traffic flow (rivers, drawbridges, railroad grade crossings, etc.);

4. Locations of fire stations, police stations, hospitals, and other offsite emergency support organizations (specify whether qualified to handle exposure to radioactive contamination or toxic chemicals);

5. The sites of potential emergency significance [e.g., liquefied petroleum gas (LPG) terminals, chemical plants, pipelines, electrical transformers, and underground cables];

6. Identification of the types of terrain and the land-use patterns around the site.

2. TYPES OF ACCIDENTS Emergency planning is concerned with individual and organizational responses to a range of potential accidents, including those accidents that have been hypothesized but that have a very low probability of occurrence.

2.1 Description of Postulated Accidents Identify and describe each type of radioactive materials accident for which actions may be needed to prevent or minimize exposure of persons offsite to radiation or radioactive materials. Exposure levels at the site boundary should be treated as the levels potentially affecting persons offsite. Describe the accidents in terms of the process and physical location where they could occur. Describe how the accidents could happen (equipment malfunction, instrument failure, human error, etc.), possible complicating factors, and possible onsite and offsite consequences. Accident descriptions should include nonradioactive hazardous material releases that could impact emergency response efforts.

Facilities that can have criticality accidents should evaluate the direct radiation exposure from postulated criticality accidents in addition to the dose from released radioactive materials. For licensees required to perform an Integrated Safety Analysis (ISA), the description should be consistent with the ISA. Guidance for conducting an ISA is provided in NUREG-1513, "Integrated Safety Analysis Guidance Document" (Ref. 10). The guidance is available at http://www.nrc.gov/reading-rm/doc-collections/nuregs/.

2.2 Detection of Accidents Describe the means provided to detect and to alert the licensee's operating staff to any abnormal operating condition or to any other danger to safe operations (e.g., a severe weather warning). For each type of accident identified in the emergency plan, describe the means of detecting the accident, the means of detecting any release of radioactive or other hazardous material, the means of alerting the operating staff, and the anticipated response of the operating staff. Examples are visual observation, radiation monitors, smoke detectors, process alarms, and criticality alarms. Indicate at what stage of the accident it would be detected. Also indicate if the area of the postulated accidents or remote readouts of alarms or detectors located in such areas are under continuous visual observation.

Rev. 1 of RG 3.67, Page 7

3. CLASSIFICATION AND NOTIFICATION OF ACCIDENTS Accidents should be classified as an alert or a site area emergency, according to the definitions in 10 CFR 30.4, 40.4, 70.4, and 76.4. (Part 63 refers to the content requirements in Part 72. Definitions for alert and site area emergency do not exist in Part 72. An acceptable approach would be the use of definitions in Part 70.) In its emergency plan and in coordination meetings with offsite authorities, the licensee should convey the concept that fuel cycle and materials facilities do not present the same degree of hazard (by orders of magnitude) as are presented by nuclear power plants. Thus, the classification scheme for these facilities is different. The licensee should explain to offsite authorities the definitions of accident severity and the expected response actions associated with alert and site area emergency conditions. NUREG-1140, "A Regulatory Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees" (Ref. 11), contains a description of past incidents involving radioactive materials.

3.1 Classification System An alert is defined as an incident that has led or could lead to a release to the environment of radioactive or other hazardous material, but the release is not expected to require a response by an offsite response organization to protect persons offsite. An alert reflects mobilization of the licensee's emergency response organization, either in a standby mode that will activate some portions of the licensee's organization or full mobilization, but does not indicate an expectation of offsite consequences. However, an alert may require offsite response organizations to respond to an onsite condition such as a fire. A site area emergency is defined as an incident that has led or could lead to a significant release to the environment of radioactive or other hazardous material and that could require a response by an offsite organization to protect persons offsite. A site area emergency reflects full mobilization of the licensee's emergency response organization and may result in requests for offsite organizations to respond to the site. Please note that emergency plans submitted under 10 CFR 72.32(a) classify accidents as alerts only. However, plans submitted under 10 CFR 72.32(b) must include a site area emergency classification. In the emergency plan, identify the classification (alert or site area emergency) that is expected for each of the accidents postulated in Section 2.1 of this guide. Relate the classification to the accident description and detection means described in Section 2.2. Identify the emergency action levels (EALs) at which an alert or site area emergency will be declared. EALs are specific conditions that require emergency response measures to be performed. Licensees should establish specific initiating conditions relative to particular events or changes in instrument sensors. Appendix A provides a list of examples of initiating conditions for declaring an alert or site area emergency. Although it is unlikely that a site area emergency requiring offsite actions will occur at a fuel cycle or materials facility, the licensee must be able to recognize potential offsite hazards and make the required notifications in such a manner that offsite response organizations can take appropriate actions, such as sheltering or evacuating persons in the affected area. NRC intends that licensees be allowed to have a single emergency plan that can apply to all licensee needs and regulatory requirements. To this end, it should be understood that a licensee may wish to include in the emergency plan some incidents that do not fall within NRC's jurisdiction. For example, the licensee may wish to include industrial accidents or fires unrelated to the licensee's work with nuclear materials. The licensee may include such incidents in the emergency plan and define special emergency classifications to avoid confusion with alerts and site area emergencies. In addition, licensees should Rev. 1 of RG 3.67, Page 8 note that alert and site area emergency classifications are intended for onsite emergencies only. If licensees ship radioactive material and intend to use the emergency plan to respond to offsite transportation accidents, the licensees should establish a separate transportation emergency classification. This issue was addressed in NRC Information Notice 93-07, "Classification of Transportation Emergencies" (Ref. 12). The notice is available at http://www.nrc.gov/reading-rm/doc-collections/gen-comm/. The classification of emergencies involving potential or actual releases of nonradioactive hazardous materials should be coordinated with the local emergency planning committee established under the provisions of Section 301(c) of the Emergency Planning and Community Right-To-Know Act of 1986 (Title III of the Superfund Amendments and Reauthorization Act of 1986, Pub. L.99-499). The licensee should clearly identify any part of the emergency plan that does not apply to activities licensed by NRC.

3.2 Notification and Coordination

3.2.1 Alert The purpose of declaring an alert is to ensure that (1) emergency personnel are alerted and at their emergency duty stations to mitigate the consequences of the accident, (2) the emergency is properly assessed, (3) offsite officials are notified, and (4) steps can be taken to escalate the response quickly if necessary. The licensee should describe how and by whom the following actions will be taken:

• Decision to declare an alert.

• Activation of onsite emergency response organization.

• Prompt notification of offsite response authorities to inform them that an alert has been declared (normally within 15 minutes of declaring an alert).

• Notification to the NRC Operations Center at 301-816-5100 immediately after notification of offsite authorities, and in any case within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of the declaration of an alert. (See 10 CFR Part 20 (Ref. 13) for additional notification requirements.)

• Decision to initiate any onsite protective actions.

• Decision to escalate to a site area emergency, if appropriate.

• Decision to request support from offsite organizations.

• Decision to terminate the emergency or enter recovery mode.

3.2.2 Site Area Emergency The purpose of declaring a site area emergency is to ensure that offsite officials are informed of potential or actual offsite consequences, that offsite officials are provided with recommended actions to protect persons offsite, and that the licensee's response organization is augmented by additional personnel and equipment. The licensee should describe how and by whom the following actions will be taken:

• Decision to declare a site area emergency.

Rev. 1 of RG 3.67, Page 9

• Activation of onsite emergency response organization.

• Prompt notification of offsite response authorities that a site area emergency has been declared, including the licensee's initial recommendation for offsite protective actions (normally within 15 minutes of declaring a site area emergency).

• Notification to the NRC Operations Center at 301-816-5100 immediately after notification of the appropriate offsite response organizations and not later than 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> after the licensee has declared a site area emergency. (See 10 CFR Part 20 for additional notification requirements.)

• Decision on what onsite protective actions to initiate.

• Decision on what offsite protective actions to recommend.

• Decision to request support from offsite organizations.

• Decision to terminate the emergency or enter recovery mode.

3.3 Information To Be Communicated The licensee should be prepared to provide clear, concise information to offsite response organizations. The communication should avoid technical terms and jargon and should be stated to prevent an under- or over-evaluation of the seriousness of the incident. Describe the types of information that will be communicated with respect to facility status, releases of radioactive or other hazardous materials, and recommendations for protective actions to be implemented by offsite response organizations. The emergency plan should contain the preplanned protective action recommendations the licensee will make to each appropriate offsite organization (including NRC) for each postulated accident. The licensee should try to make protective action recommendations directly to State or local officials responsible for implementing the specific protective actions. The recommendations should specify the size of the area where the actions are to be taken. The licensee should obtain the input of offsite organizations to ensure that they recommend the most practical and efficient protective actions for each postulated accident. A standard reporting checklist should be developed to facilitate timely notification. Provide assurance to NRC that the information has been received by offsite response organizations and that it is periodically reaffirmed and updated with these agencies. The standard reporting checklist should be developed in cooperation with offsite officials, to ensure that it meets their information needs and that their personnel are trained to receive and relay such information. The licensee should provide initial protective action recommendations at the same time it initially notifies offsite authorities of a site area emergency declaration.

4. RESPONSIBILITIES In this section, describe the emergency organization to be activated onsite for possible events, as well as its augmentation and support offsite. Delineate the authorities and responsibilities of key individuals and groups, and identify the communication chain for notifying and mobilizing the necessary personnel during normal and nonworking hours.

4.1 Normal Facility Organization Provide a brief description of the normal (day-to-day) facility organization and identify by position those individuals who have the responsibility and authority to declare an emergency and to Rev. 1 of RG 3.67, Page 10 initiate the appropriate response. In addition, identify by position those individuals responsible for developing, maintaining, and updating the emergency plan.

4.2 Onsite Emergency Response Organization Describe the onsite emergency response organization for the facility, and include the organization for periods such as offshift, holidays, weekends, and extended outages when normal operations are not being conducted. Use organization charts and tables when appropriate. If the organization is activated in phases, describe the basic organization and each additional component that may be activated to augment the organization.

4.2.1 Direction and Coordination Designate the position of the person (and alternates) who has (have) the overall responsibility for implementing and directing the emergency response. Discuss this person's duties and authority, including control of the situation, termination of the emergency condition, coordination of the staff and offsite personnel who augment the staff, communication with parties requesting information about the event, authority to request support from offsite agencies, and authority to delegate responsibilities. Indicate the individuals who may be delegated certain emergency responsibilities.

4.2.2 Onsite Staff Emergency Assignments Specify the organizational group or groups assigned to the functional areas of emergency activity listed below. Indicate the basis for personnel assignment for both working and nonworking time periods.

For each group, describe duties, authority, and interface with other groups and outside assistance. The organizational groups should provide capability in the following areas:

• Facility system operations

• Fire control

• Personnel evacuation and accountability

• Search and rescue operations

• First aid

• Communications

• Radiological survey and assessment (onsite and offsite)

• Personnel decontamination

• Facility decontamination

• Facility security and access control

• Facility repair and damage control

• Post-event assessment Rev. 1 of RG 3.67, Page 11

• Recordkeeping

• Media contact

• Criticality safety assessment

4.3 Local Offsite Assistance to Facility Describe provisions and arrangements for assistance to onsite personnel during and after an emergency. Indicate the location of local assistance with respect to the facility if not previously stated. Ensure that exposure guidelines are clearly communicated to offsite emergency response personnel. Identify the services to be performed, means of communication and notification, and type of agreements that are in place for the following:

• Medical treatment facilities

• First aid personnel

• Fire fighters

• Law enforcement assistance

• Ambulance service Describe the measures that will be taken to ensure that offsite agencies maintain an awareness of their respective roles in an emergency and have the necessary periodic training, equipment, and supplies to carry out their emergency response functions. Discuss any provisions to suspend security or safeguards measures for site access during an emergency.

4.4 Coordination with Participating Government Agencies Identify the principal State agency and other government (local, county, State, and Federal) agencies or organizations having responsibilities for radiological or other hazardous material emergencies at the facility. For each agency or organization, describe:

• Its authority and responsibility in a radiological or hazardous material emergency and its interface with others, if any;

• Its specific response capabilities in terms of personnel and resources available;

• Its location with respect to the facility;

• The rumor control arrangements that have been made with the agency or organization. (The emergency plan should describe where the public and media can obtain information during an emergency.) Typical agencies to be included are the local emergency planning committee established under the Emergency Planning and Community Right-To-Know Act of 1986; State departments of health, environmental protection, and emergency or disaster control; and local fire and police departments. Ensure that the licensee will meet at least annually with each offsite response organization to review items of mutual interest, including relevant changes in the licensee's emergency preparedness program. The Rev. 1 of RG 3.67, Page 12 licensee should discuss the emergency action level scheme, notification procedures, and overall response coordination process during these meetings.

5. EMERGENCY RESPONSE MEASURES Specific emergency response measures should be identified for each class of emergency and related to action levels or criteria that specify when the measures are to be affected. Response measures include assessment actions, mitigating actions, onsite and offsite protective actions, exposure control, authorization of emergency exposures in excess of Part 20 limits, and aid to injured persons.

5.1 Activation of Emergency Response Organization Describe the means used to activate the emergency response organization for each class of emergency during both regular and nonregular hours. Include a description of the method used to authenticate messages. Identify the activation levels for each class and relate them to the responsibilities identified in Chapter 4 of this Regulatory Guide. In this and subsequent sections, describe the specific written procedures to be used. In this and subsequent sections, describe how the response changes when the emergency involves a hostile action. A hostile action is an act towards a facility or its personnel that includes the use of violent force to destroy equipment, take hostages, and/or intimidate the licensee to achieve an end. The description should be general and should reference other documents for details that must be protected as Safeguards Information (10 CFR Part 73 (Ref. 14)) or classified information (10 CFR Parts 25 (Ref. 15) and 95 (Ref. 16)). Guidance on hostile action-based drills is provided in Information Notice 2009-19 (Ref. 18). This notice discusses lessons learned during hostile action-based drills at reactor sites. A non-reactor site can expect similar problems and should address these issues in its plan.

5.2 Assessment Actions For each class of emergency, discuss the actions to be taken to determine the extent of the problem and to decide what corrective actions may be required. Describe the types and methods of onsite and offsite sampling and monitoring that will be done in case of a release of radioactive or other hazardous material. Describe provisions for projection of offsite radiation exposures.

5.3 Mitigating Actions For the events identified in Section 2, briefly describe the means and equipment provided for mitigating the consequences of each type of accident. Include the mitigation of consequences to workers onsite as well as to the public offsite. In the event of a warning of impending danger, describe the criteria that will be used to decide whether a single process or the entire facility will be shut down, the steps that will be taken to ensure a safe orderly shutdown of equipment, and approximate times required to accomplish a safe shutdown of processes. Mitigating actions could include steps to reduce or stop any releases and steps to protect personnel and environment (e.g., evacuation, shelter, decontamination). Means for limiting releases could include:

• Sprinkler systems and other fire-suppression systems

Topics to be addressed during training for offsite emergency response personnel should include exposure guidelines, personnel monitoring devices, and basic contamination-control principles.

7.3 Drills and Exercises Describe provisions for periodic drills and exercises to test the adequacy of implementing procedures, to test emergency equipment and instrumentation, and to ensure that the emergency personnel are familiar with their duties. Applicants should note that 10 CFR 72.32 contains a unique requirement that Radiological/Health Physics, Medical, and Fire Drills shall be conducted annually by Part 72 licensees. Typically, drills are internal tests of specific licensee emergency response functions, related functions are often simulated, and offsite organizations are not invited to participate. Exercises are typically full-scale tests of the licensee's entire emergency response organization, and offsite organizations are invited to participate. It is expected that internal drills will be conducted more often (at least annually) than full-scale exercises. Each applicant should establish a drill frequency that will maintain proficiency in its emergency response organization. Preplanned descriptions of accidents should be used to prepare scenarios appropriate to the objective of each drill and exercise. Scenarios should be developed for the accidents postulated in the plan including hostile-action based events. The procedures should include a requirement for one or more nonparticipating observers to evaluate the effectiveness of the personnel, the procedures, the readiness of equipment and instrumentation, and to recommend needed changes. For those drills and exercises that involve simultaneous activities at more than one location, observers should be provided at each location. Describe how criteria for acceptable performance will be prepared and provided to observers for evaluating the performance of participants.

Rev. 1 of RG 3.67, Page 18

7.3.1 Biennial Exercises Ensure that an exercise will be held biennially and that offsite response organizations will be invited to participate in the biennial exercise, to exercise coordination with offsite assistance organizations, including testing procedures and equipment for notifying and communicating with local and State agencies. Ensure that NRC will be invited to participate or observe if it wishes. Ensure that exercise scenarios are not known by exercise participants and are plausible for the specific site. Discuss any provisions to suspend security or safeguards measures for site access during an exercise. These exercises should be planned so that all emergency response activities are adequately demonstrated. The exercise objectives and scenario should be provided to NRC at least 60 days before the exercise, to obtain NRC comments on how well the exercise will test the licensee's emergency response capabilities.

7.3.2 Quarterly Communications Checks Ensure that checks are conducted with offsite response organizations each quarter to verify and update all necessary telephone numbers.

7.4 Critiques Ensure that a critique will be prepared for each drill and exercise by one or more of the nonparticipating observers and that it will evaluate the appropriateness of the emergency plan, procedures, facilities, equipment, personnel training, and overall effectiveness. The emergency plan and implementing procedures should be reviewed after each exercise, based on the evaluation of the exercise.

The emergency plan should be reviewed and revised, if necessary, whenever changes occur in processes, kinds of material at risk, or plant organization. Describe how deficiencies identified by the critique will be corrected in a timely manner. (See Chapter 8 for records of exercises and exercise critiques.)

7.5 Independent Audit Discuss the program to be used annually to review and audit the licensee's emergency preparedness program, including the emergency plan and its procedures; training activities; emergency facilities, equipment, and supplies; and records associated with offsite support agency interface, to ensure that the overall emergency preparedness program is being adequately maintained. Describe the minimum qualifications of the persons who will perform the annual audit and ensure that the audits will be made by persons not having direct responsibilities for implementing the emergency response program. Describe the provisions for initiating corrective actions based on audit findings and for ensuring completion of these actions.

7.6 Maintenance and Inventory of Emergency Equipment, Instrumentation, and Supplies Describe the plans for ensuring that the equipment and instrumentation are in good working condition and that an adequate stock of supplies is maintained. A quarterly inventory should be made to ensure all emergency equipment and supplies are intact and in good operating condition, including instrumentation for operation and calibration, demand respirators, self-contained breathing apparatus, firefighting equipment and gear, supplemental lighting, and communications equipment. The procedures should include timely corrective actions to be taken when deficiencies are found during these checks.

7.7 Letters of Agreement Changes to the emergency plan should be communicated to the appropriate offsite response organizations; ensure that letters of agreement with offsite agencies are reviewed annually and renewed at Rev. 1 of RG 3.67, Page 19 least every 4 years or more frequently, if needed. Letters of agreement may be included in the emergency plan or maintained separately.

8. RECORDS AND REPORTS

8.1 Records of Incidents Describe the assignment of responsibility for reporting and recording incidents of abnormal operation, equipment failure, and accidents that led to a plant emergency, including permanent retention with the licensee's decommissioning records. Provide a detailed description of the records that will be kept. The records should include the cause of the incident, personnel and equipment involved, extent of injury and damage (onsite and offsite) resulting from the incident, all locations of contamination with the final decontamination survey results, corrective actions taken to terminate the emergency, and the action taken or planned to prevent a recurrence of the incident. The records should also include the onsite and offsite support assistance requested and received, as well as any program changes resulting from the lessons learned from a critique of emergency response activities. The titles of the personnel responsible for maintaining the records should be specified. Those records unique to a radiological emergency, not covered by existing NRC regulations or license conditions, should be retained until the license is terminated.

8.2 Records of Preparedness Assurance Provide a description of the records that will be kept. These should include records of:

• Training and retraining (including lesson plans and test questions)

• Drills, exercises, and related critiques

• Inventory and locations of emergency equipment and supplies

• Agreements with offsite support organizations

• Reviews and updates of the emergency plan

• Notification of all personnel and offsite agencies affected by an update of the plan or its implementing procedures.

9. RECOVERY AND PLANT RESTORATION Describe plans for restoring the facility to a safe status. Although it is not possible to detail specific plans for every type of incident, the plans should include the general requirements for: (1) assessing the damage to, and the status of the facility's capabilities to, control radioactive materials; (2) determining the actions necessary to reduce any ongoing releases of radioactive or other hazardous material and to prevent further incidents; (3) accomplishing the tasks to meet any required restoration action, and; (4) describing in general the key positions in the recovery organization. Specifically, recovery plans should include requirements for checking and restoring to normal operations all safety-related equipment involved in the incident (e.g., criticality alarms, radiation-monitoring instruments, respiratory protection equipment, fire-suppression and fire-fighting equipment, Rev. 1 of RG 3.67, Page 20 containments, and air filters) and assignment of responsibility for compiling, evaluating, and ensuring retention of all records associated with the incident. During any planned restoration operations, personnel exposures to radiation must be maintained within Part 20 limits and maintained as low as reasonably achievable.

10. COMPLIANCE WITH COMMUNITY RIGHT-TO-KNOW ACT Certify compliance with Title III of the Superfund Amendments and Reauthorization Act of 1986, Pub. L.99-499, entitled "Emergency Planning and Community Right-To-Know Act of 1986," with respect to any hazardous materials possessed at the plant site.
