Advanced Modular Simulation Techniques for Nuclear Power Plants

An advanced technique to simulate nuclear power plants and other complex system was developed. The simulation technique is based on the DSNP (Dynamic Simulator for Nuclear Power-plants) simulation language. The DSNP is a modular modeling technique having several libraries with a large selection of component modules. Several examples are presented on how these modules are brought together to create a simulation program for a specific PWR, IITGR, and LMFBR plants. Results of some transients and accidents simulation are presented to demonstrate the DSNP capability and its versatility.
