The nuclear propulsion plant of the N.S. Savannah is simplified
and simulated using Digital Simulation Language. The plant is
subjected to an up power transient of sixty-five percent and a
down power transient of eighty percent. Constraints are imposed
to limit power excursions, minimize reactor coolant hot leg temperature
and maximize boiler saturation temperature while maintaining
average coolant temperature constant. Combinations of
control rod movement and changes in reactor coolant flow rate are
studied in order to determine the control systems that best satisfy
the constraints and minimize the time to steady state for each
transient.
