Abstract
A method and system of simulating the dynamic real-time operation of a nuclear power plant wherein a plurality of manually operable devices provide input data to a digital computer to calculate physical values corresponding to plant operation to operate indicating devices for monitoring the operation of the plant. It includes the simulation of a feedwater system comprising a number of parallel and series connected feedwater heaters. The simulation of the feedwater heating system is effected by lumping the feedwater heaters into single equivalent heaters for purposes of calculation. Non-linearity of the system is simulated by using a piecewise cubic polynominal or spline fit function of the physical properties of steam and water at saturation. The node-points of the spline curve are obtained by using a second derivative of the physical variable to determine iteratively the optimum node positions.
