Abstract
Abstract For automation of routine monitoring and control duties and for retrofitting the aging control and protection system of the 33-year-old swimming-pool reactor SAPHIR at PSI, a digital data aquisition and control system, based on microprocessors with intelligent and remote multiplexing capabilities and strictly cyclic and deterministic signal processing is being developed. The implementation of this functionally and geographically distributed system leads to an improved man/machine interface and is welcomed by the Swiss regulatory authorities as a contribution to the nuclear qualification of digital reactor protection systems for future reactor facilities like district heating reactors or gas-cooled high temperature reactors. The demonstration and testing on an already operating research reactor with a proven, conventional protection system as a backup has the benefit of not being subject to the time critical licensing procedures for new reactors.
