Multipurpose modelling complexes as a basis for investigating heavy accidents, designing and improving control system of NPP

The simulators being developed and introduced in design-construction, scientific-research organizations and at NPPs, which combine capabilities of simulating complexes, training facilities, emergency situation analyzers and operator assistance system (process predictors), are discussed. The simplified variant of full-scale engineering simulators is designed on the base of using the main principles of the system functional-algorithmic structure construction. 5 refs., 1 tab
