NUCLEAR MERCHANT SHIP REACTOR PROJECT, DESCRIPTION OF THE REACTOR CONTROL SYSTEM
Semi-automatic reactor control system design maintains a constant average primary coolant temperature during steady-state. This minimizes the size of the pressurizer and allows fast maneuvering rate utilization. Coolant temperature and throttle position variations are detected by sensors and corrective action is taken to the control rods through the coolant system. The corrective signal initiates movement of a rod group with a proportional velocity up to a preset limit which restricts the reactivity insertion rates to a safe value and still permits rapid maneuvering of the plant. The control system prevents excessive transients of the primary coolant temperatures during demand load changes.
