Abstract

The design of a physical model of the PBMR with the aid of the code Flownet is discussed in this paper. The purpose of the physical model is to test the control strategies and operating procedures of the PBMR and also to demonstrate the accuracy of Flownet. Flownet is first used to do component matching and to determine the detail 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 model of the PBMR can be designed with the aid of a powerful simulation tool in a relatively short period of time and at low cost using commercially available turbochargers.
