ISSUE TITLE Need for effective off-site communications during events (EP 1) 

A reliable communication system is definitely needed between a nuclear power plant and the relevant offices, including the regulatory body located outside the plant site during and after an accident. Special consideration has to be given in maintaining the system function for internal and external events such as fire and earthquake. The preparation of appropriate procedures and the training of the plant staff for communication in the emergency is necessary. 

The loss of off-site communication during and after an accident can prevent a stematic approach to technical assistance in an emergency from relevant organizations outside the plant and appropriate response actions by public authorities. It also impairs communication flow from a plant to the public and sometimes distorts information on progression and consequences of an accident. 

Experience with voice and emergency communications links has demonstrated that excessive amounts of time are needed for the routine transmission of data and that verification or correction of data appear questionable. Incorrect data may cause a response to offsite officials with inaccurate or outdated advice that results in inappropriate actions. 

The setting up and the effectiveness of such a management system depends on rapid mobilization of the teams involved and multiple telecommunication resources.
