Abstract
In a nuclear facility a round-the clock surveillance of the radiation levels in selected areas is necessary and usually required by the national regulatory institutions. In addition the instrument readings have to be recorded automatically and stored for a longer period, typically 10 years. One problem with such systems is the accumulation of a large amount of radiation data which are very difficult to review and store. Usually only a small fraction of data (i.e. when exceeding preset alarm levels) are of interest while the rest of the data are more or less unnecessary although their storage is required for continuous documentation.
As a compromise between storage of all data but immediate information on important data (i.e. alarms) an area surveillance system has been designed and installed at the TRIGA reactor Vienna using a data logger and a personal computer as a storage facility. In total 16 radiation monitor signals are permanently scanned by a multiplexer for deviation from normal operation values. These data are printed out every full hour while in case of an excess radiation level alarm is triggered optically and acoustically and the relevant monitors are listed together with the radiation levels. All the data are transferred to the institute’s central computer (VAX 11/750) where they are available for further processing in a proper file structure.
