The third generation of the remote monitoring system for nuclear reactors in Bavaria

The first remote monitoring system for nuclear reactors (KFU) world-wide wa s commissioned in Bavaria in 1978. The purpose of remote monitoring of nucl ear reactors is to continuously monitor, independent of the operator import ant parameters to control the plant operation, the discharges of radioactiv e effluents, the meteorological conditions at the site and the radiological situation in the vicinity of the plant and to transmit these data to the s upervisory authority. Progress in computer technology has stimulated improv ements in the structure of the KFU and will continue to no so. Modern high- performance servers ave linked in a local area network (LAN) in the Bavaria n KFU of the third generation, having started operating recently. A Lagrang ian atmospheric dispersion model has been implemented for the diagnosis of the actual radiological situation in the vicinity and the prognosis of the further development of this situation. Data exchange with the Federal autho rities is possible, in principle. KFU data from off-sire monitoring are als o made available to the public.
