Abstract: A recent review of the procedures covering the RPII's responsibilities under the National Emergency Plan for Nuclear Accidents has shown the need for a management information system (MIS) to support the organisation's operational plan for emergency preparedness and response. This paper describes the design objectives and the development of a prototype version of this system. Specific functions of the MIS are highlighted along with a description of the motivation behind their development. This very simple MIS has already helped RPII staff members to operate more efficiently. Finally, some ideas for future development are outlined. Â© Proceedings ISCRAM 2004.
