ABSTRACT
An analog simulator with specially designed electromechanical equipment was developed to simulate one of three loops of the Enrico Fermi Atomic Power Plant, including all elements except the steam turbine; i.e., the reactor, intermediate heat exchanger, steam generator, mixing and transport delay phenomena, and steam system hydraulics.
A philosophy of plant control was evolved on the basis of plant operating characteristics, as determined by the simulator and supported by a steady-state digital analysis of the plant. Conceptual control hardware designs were then tested on the simulator and an optimum design was selected and tuned. Actual hardware of the automatic control system was simulated, and this simulation circuitry incorporated in the computer.
Control consoles exactly duplicating the control panel layout in the actual plant were connected to the analog simulator to adapt it for power plant operator training. Trainees thus get the "feel" of plant operating characteristics, learn to meet emergencies, and practice standard operating procedures, using both manual and automatic controls.
The facility has already proved valuable in studying normal and abnormal operating conditions and remains available for any future systems analysis needs; meanwhile it is in continuing service for operator training.
