Simulation Research About China Experimental Fast Reactor Steam Turboset Based on Flowmaster Platform

In the third loop of China Experimental Fast Reactor (CEFR), steam turbosets take an important role in converting hear energy into electric energy. However, turbosets have not been operated on the condition of more than 40%P₀（P₀ is full power） since they were installed. Thus it is necessary to make an analogue simulation. Based on the real models of turbosets in CEFR, simulation models were created with the help of Flowmaster platform. By using such simulation models, a steady state result in full power circumstance was got, which is in accordance with design parameters. Meanwhile, a transient state simulation with operating condition ranging from full power to 40% P₀ was accomplished and a result which verifies part of performance and running conditions of turbosets was got. The result of analogue simulation shows that based on Flowmaster platform, the running condition of simulation models can comply with design requirement, and offer reference values to the actual running. Such simulation models can also offer reference values to other simulation models in the third loop of CEFR.
