Pebble Bed Micro Model system identification

Abstract

Linear system identification techniques will be applied to obtain mathematical models of a simulation of the Pebble Bed Micro Model (PBMM). The PBMM is a conceptual model of the Pebble Bed Modular Reactor (PBMR), a new high temperature gas nuclear reactor. The basis of the PBMR and PBMM is a three-phase Brayton Power Generation Cycle. The Brayton cycle will in this paper be simulated by the use of Flownex, a general thermal-fluid network analysis code solver. A description of the Brayton Power Generation Cycle, as well as description of the Flownex modelling program, will also be given.
