| Abstract: | A digital computer system was developed for automatic operation of the Toshiba Sodium Test Loops, intended for studying the control system of liquid metal fast breeder reactors. The test installation is controlled by a system of two TOSBAC-40C central processing units, which take care of plant monitoring, data logging, information display, sequence control and closed loop control. The operator console linked to the computers can handle more than 3,000 process input/output signals. The state of the plant and measured data are displayed on two color cathode-ray tube installed on the console. Normal operation of the four loops constituting the installation can be supervised by one single operator. Safety in the case of power failure and other emergencies is assured by a safety protection system that functions independently of the computer system. |
