A BWR Power Plant Simulator for Barsebäck

A computer simulator of a Barseback power plant unit has been developed in cooperation between Sydkraft AB, Lund Institute of Technology, and Risø National Laboratory. The simulator is of the kind often referred to as a compact simulator, because it involves only a computer with display screens and other input/output devices plus the software needed for calculation and presentation of the plant state as a function of time, and no sort of model of the control room as in large reactor simulators for operator training. The purpose of training courses with the compact simulator is to give students a better understanding of the behaviour of the power plant under transient conditions by displaying variables, e.g. pressures, temperatures, reactivity, nuclear power, as functions of time, thereby showing the interactions between different parts of the plant during the transient and the influence of a number of possible operator actions. The present paper describes the Barseback compact simulator with the emphasis on the software developed at Risø National Laboratory. The Risø work comprises the programming of the dynamic plant model, in the form of a number of Fortran subroutines containing the physical description of the power plant.
