Design of a physical model of the PBMR with the aid of Flownet

The design of a physical model of the power conversion cycle of the pebble bed modular reactor (PBMR) with the aid of the code Flownet is discussed in this paper. The purpose of the physical model is to demonstrate the control strategies and operating procedures of the PBMR and also to demonstrate the accuracy of the simulation code Flownet. Flownet is first used to do component matching and to determine the detailed steady-state performance of the system. It is then demonstrated how the code was used to simulate the start-up procedure as well as a load following and a load rejection scenario. The study demonstrates how a micro turbine system can be designed with the aid of a powerful simulation tool in a relatively short period of time at low Cost using commercially available turbochargers.
