Automated system of in-service diagnostics for Temelin nuclear power plant

The diagnostic system of the Temelin nuclear power plant primary coolant circuit of unit 1 is described with respect to the concept of a decentralized structure consisting of autonomous diagnostic subsystems based on microcomputers, to the frequency band of diagnostic signals, the number and location of the pick-ups, the method of evaluating pick-up signals, and to computer operators. The possibility is discussed of linking the in-service diagnostics system to the reactor (power plant) inspection and control system. (author)
