On-site and off-site emergency planning at Cekmece nuclear research and training centre

ABSTRACT

An emergency plan was prepared for minimizing the consequences of any unforeseen radiation accident in Cekmece Nuclear Research and Training Centre (CNAEM) in Istanbul, Turkey. CNAEM is situated near Kücükcekmece Lake, which is about 30 km to the west of Istanbul. It includes two pool-type research reactors of 1 MW(th) and 5 MW(th). The population in the nearest inhabited areas varies from 1000 to 50000. Accidents are classified, according to their severity, into three categories al CNAEM (a)local emergency, (b)on-site emergency, (c)off-site emergency. During local emergency situations evacuation is not necessary. An on-site emergency situation requires the evacuation of personnel from the plant. Personnel hearing the emergency alarm should move directly to the preselected place as soon as possible. An off-site emergency is any accident that leads to widespread contamination outside the boundary. In this situation the Turkish Atomic Energy Authority and governmental authorities are notified immediately. The emergency organization group consists of (a)Plant Superintendent, (b)Emergency Director, (c)Reactor Supervisor, (d)Senior Health Physicist, (e)Reactor Shift Operator, (f)Health Physicists. The administration building will be used as the Emergency Control Centre. The emergency teams working under the direction of the Emergency Director consist of (a)Health Physics, (b)Fire and Rescue, (c) First Aid and Decontamination, (d)Transportation, (e)Security and Patrol. The emergency situation is evaluated in three phases al CNAEM. The first phase is the first few hours after the beginning of the accident. The second phase is between 8-10 hours or more following the first phase. The third phase is the recovery phase. The integrated doses over periods of two hours and two days are calculated according to the situation of the core, i.e. total or patial melting, and weather conditions. The results of the calculated parameters can be adapted to possible accident as reference. (AU)
