Auxiliary and main control in a BWR-5

Running any kind of power plant leads to the use of simulators for training operators. Simulators are particularly important in the case of nuclear power plants due to the great number of variables that must be controlled and the consequent errors that can be incurred in by the operator. Moreover, the cost of such simulators impels us to seek new and better techniques to implement these didactic tools. Mathematical models that describe the physical components of the plant are the most important part of the simulator. Within these, the control models are particularly important due to the great amount of interactions with the control panels and the other subsystem's models. The control system models for the control room's principal panel are described in this report. The control models are divided in two: principle and auxiliary. The principle models include the recirculation and the feed water control system, while auxiliary mdes are: reactor core isolation cooling system, reactor heat removal system and turbine closed cooling water system
