A steam-tube dispersion model has been adapted to real-time simulation of heat dispersion in a 7-mile reach of the Des Plaines River below Joliet Power Station. Direct feedback control to comply with environmental temperature standards is not possible because the control point is located 7 miles downstram of the Station. A compliance strategy based on real-time simulation is being developed to identify the amount and scheduling of Station derating required to respect the compliance standard.
