13.A.1 Appendix 13.A E'!ERGENCY PLANS FOR Tile MIT REACTOR 13.A.1 Introduction In a facility with as many varied activities as are carried out around the FET Reactor, it is desirable to have plans for action in the event of emergencies.

Although the real need for such plans is believed to be remote, the existence of the plans will serve two purposes. First, it will provide assurance of planned preparedness for emergencies as a part of the nornal facility operations. Second, the occasional testing of the plans will remind all concerned of the real individual responsibilitics that are connected with the various activities to uhich they are assigned.

The MITR energency plans are divided into four separate parts:

a) Radiation Energency Plan b) Medical Emergency Plan c) Reactor Evacuation Plan d) Reactor Operating Energency Plan.

13.A.2 FETR Emergency Plans 13.A.2.1 General The following information applies to all four energency plans.

13.A.2.1.1 Responsibility and Authority Normal operating authority is described in Section 13.1 of the SAR. In the event of an emergency the normal reactor staff can be rapidly supplemented by out-side assistance.

The senior NRC-licensed staff member on shift ~ (Senior Reactor Operator or above) is responsible for decisions and coordination of all immediate actions in an emergency.

lie will be responsible for all on-site and off-site actions. When additional super-visory personnel become available, the senior member of the operations group present shall have overall responsibility and, in particular, shall arrange to relieve the on-site shif t supervisor of responsibility for the handling of of f-site operations.

SR#-0-75-41 April 4, 1975

SAR 13.A.2-1 Both the Reactor Operations Of fice (Bldg. NW12), the Environrental Medical Service Office (Bldg. 20), and the Campus Patrol Headquarters (Bldg. W31) will be equipped to act as energency centers for off-site activity. The Reactor Control Room, if habitable, will serve as the center for on-site operations; otherwise these activities will be directed from the appropriate designated emergency center.

The designated emergency center will be determined by meteorological conditions.

The off-site supervisor will take charge of off-site operations upon being briefed by the reactor supervisor on duty.

The Radiation Protection group shall assist the senior staf f menber from Reactor Operations responsible in evaluating the potential radiation hazards encountered and possible neans of protection for the public and the personnel involved in the emergency action. This is an advisory function and does not fit into the chain of command structure.

The ultimate responsibility remains with the Director of Reactor Operations or his designated alternate.

The of f-site supervisor will be responsible for and direct all off-site operations involving MIT personnel and for maintaining the liaison between MIT and assisting agencies (i.e., Cambridge Police and Fire).

The chain of command is shown in Figure 13.A.2.1.1-1. The flow of information and lines of command with off-site agencies and radiation survey teams are outlined in Figure 13.A.2.1.1-2.

Cambridge Police and Fire Departments have the authority to limit access and evacuate areas in Cambridge and will do so on the advice of the MIT Reactor Supervisor.

IET Campus Patrol has the authority to limit access and evacuate areas on the MIT canpus and will do so on the advice of the tRT Reactor Supervisor.

SR#-0-79-13 June 8, 1979

SAR 11.A.2-2 The energency plan and associated procedures and all significant nodifica-tions thereto shall be approved by the MIT Reactor Safeguards Connittee before implementation. Periodic revleus of the Emergency Plan and Proceduces shall be performed by the Committee.

13.A.2.1.2 Personnel The Reactor Operations licensed staf f normally consists of: the Director of Reactor Operations, the Superintendent, Senior Shift Supervisors (who are normally graduate students in the MIT Nuclear Engineering Department), Shif t Supervisors and Reactor Operators. For three shift operation, the above staff normally consists of approximately 11 personnel. There are, in addition, 10 to 15 mechanics, technicians and machinists who are familiar with reactor procedures.

During the day shif t, personnel are availabic on-site to supplement the operating crew in an emergency.

The MIT Radiation Protection Office has a Radiation Protection Officer (a trained health physicist) and three Radiation Protection Technicians assigned to the reactor. As a result of the large amount of research which is being conducted at other MIT labs and which involves radiation, there are several Radiation Pro-tection perscnnel available who are familiar with radiation protection procedures.

These peopic are trained health physicists and all are experienced in the use of radiation monitoring equipment.

In addition to the Operations and Radiation Protection staff, approximately 100 persons are issued film badges and are f amiliar with the reactor and basic radiation protection. All persons issued film badges are given a guide entitled

" Required Procedures for Radiation Protection" and a lecture on procedures to be followed at the MITR. In addition many students who are issued film badges have taken laboratory or other classes in the use of radiation monitoring equipment.

Students are encouraged and helped in daveloping skill with monitoring equipment.

Film badge holders can be called on a voluntary basis for service in an coorgency.

SRO-0-79-13 June 8, 1979

SAR 13.A.2-3 The MIT Campus Patrol will do the initial monitoring under certain emergency conditions. Therefore they are trained by the MITR staff in the use of monitoring equipment and procedures. Many of the Campus Patrol have had prior experience with radiation equipment and the training session is in p.rt to acquaint and familiarize them with the MITR and its equipment. The Campus PsD21 will coordinate communica-tions with local off-site agencies (i.e., Cambridge Fire and Police).

13.A.2.1.3 Trainin g All licensed employees receive detailed instruction and testing of emergency procedures during license training. All other employees and experimenters receive nanuals and lectures by the Radiation Protection Of ficer and the Reactor Operations Superintendent before being issued a film hadge.

Since the MITR is a research reactor many of the experimenters are students who have been instructed in the use of monitoring equipment and procedures.

The staf f of the Radiation Protection Of fice is composed of health physicists and trained technicians. They are continually using radiation nonitoring equipment in their daily work routine. In addition, as a result of the large number of facilities at MIT which use radioactivity the RPO staff has had the opnortunity to develop expertise in handling radioactivity in energency situations.

The MIT Campus Patrol in addition to its training and familiarity with monitoring equipment is also trained and f amiliar with breathing devices and other protective measures. The MIT Campus Patrol is given a tour of the MIT Reactor and made familiar with the facility, the operations staff, and the emergency procedures annually.

Communications are an integral part of the daily campus patrol uork and no additional training is necessary.

The Cambridge Fire Department receives training in the control of fires involving toxic materials. The training is similar to what is needed for a fire containing radioactive materials. The Fire Department personnel are trained in the use of self-contained breathing apparatus and monitoring for radioactivity. The Fire Departnent can provide additional monitoring capability if requested. Firemen who may respend S R#-0-76-31 October 8, 1976

SAR 13.A.2-4 to a call from the MITR either for a fire or a radiation emergency are given a tour of the reactor and a lecture on procedures.

13.A.2.1.4 _ Testing and Evaluation Periodic tests and drills of the Emergency Procedures are done in accordance with a schedule maintained by the Reactor Operations Superintendent. In particular, testing of the Radiation Emergency Procedure, Action IX, described in Section

13. A.2.4.1 including participation by the MIT Campus Patrol and communication with the Canbridge Police and Fire Departments, but not including active participation by either, is done at least once every year.

Each test or drill is conducted under the supervision of a member of the Reactor Operations group who is assigned responsibility for evaluating the results of the test or drill. Ile prepares a written report of his evaluation including reconmenda-tions for improving and up-dating the Plan, the Procedures, or both.

13. A.2.1.5 Priorities and Guidi.1g Linit of Exposure In the event that the reactor building is evacuated or it becomes necessary to 1 cave the control room to perforn certain tasks, an exposure guideline becomes necessary.

In the follouing table the various types of possibic recovery tasks are classi-fled with respect to priority and maximum exposure.

Guideline For Maximum Recovery Tasks Priority Exposure A. Saving a human life high 100 rem B. Establishing the nuclear safety of the reactor (only if immediate action is required to protect the general public) high 25 rem C. Safety or protection of major equipment not vital for the nuclear safety of the reactor low 3 rem D.

13.A.2.2.4 Escape of Airborne Radioactive Material From the Reactor Containment The procedure to deal with abnormal escape of airborne radioactive naterial from the reactor containment is divided into two separate action categories that depend on the amount of radioactive material that escapes the containment (as measured by the duration of the escape and the dose rate at the point of escape) weighted by the permissible concentration of the escaping material. Guides con-tained in the procedure will assist operations personnel in making the necessary decisions. These decisions will be based on readings available from the control SR#-0-79-13 June 8,1979

13.A.2-8 room instrumentation, from the Reactor Radiation Protection Office (RRPO) environ-nental monitors, or the results of outside radiation surveys. The control room and RPO instrumentation used for measurements are described in Section 12.3.2.4 of the SAR. The ranges, sensitivities and response times of both this instrumen-tation and the survey tean instruments are adequate to conservatively assess the need for the action below.

The decision for implementation of the Emergency Procedures will be made on the basis of the reactor effluent monitors, which read inside and outside the containment, coupled with a very conservative dilution factor of 1000 and assuming until proven differently, that the isotope released is one with the minimum possible KPC.

Decisions for evacuation or other protective action involving the surrounding population will be based on the survey team results of measurenents made in the field.

The reactor effluent monitors are calibrated on a frequency given by Technical Specifications, while the environmental nonitors and the survey tean instrunents are calibrated at least annually.

13.A.2.2.4.1 Action IX Action IX will be put into effect if there is danger that people in the path of the effluent might receive an integrated internal dose of more than 10 rem from airborne radioactive materials as a result of exposure to the effluent for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

This is twice the pernissible yearly occupational doses and is a level which has been determined af ter due consideration of the potential risks associated with evacu-ation or other protective action involving the surrounding population. MIT Campus Patrol and Cambridge Police and Fire Departnents will be called innediately so that people in the path of the effluent radioactive material vny be advised to take cover as quickly as possible, or evacuate if necessary.

SR#-0-79-13 June 8, 1979

SAR 13.A.2-8a 13.A.2.2.4.2 Action 2X Action 2X will be taken if the escape of the effluent is small and/or momentary such that there is expected to be at least one hour available to monitor the path of the effluent prior to deciding on the required action.

Tne main difference between this action and action IX is that initially only the Campus Patrol will be called. If integrated exposures are expected to exceed 5 rem, the following civil authorities will be immediately notified:

1. Cambridge Police and Fire Departments

2. Massachusetts Department of Public Health

3. USNRC, Office of Inspection and Enforcement, Region 1.
