A High Fidelity JTopmeret? Model for Gas-Cooled Reactors
The Jtopmeret? Two-phase thermal-hydraulic code has been widely used to provide high fidelity Balance-of-Plant (BOP) real-time simulator models for conventional Nuclear and Fossil reactors. Recently, several models essential to simulate components of gas reactors were developed and integrated within Jtopmeret?. These models include gas transport medium (Helium and CO2,with real gas thermodynamic properties), large scale gas power turbine and gas compressor (blower), heat exchangers (recuperators and coolers), and a three-dimensional graphite core structure interspersed with gas coolant flows. These models have been presented in earlier papers 1,2,3. This paper shall provide an overview of the models, and demonstrate full modeling capabilities for two major reactor types. One is a conventional Advanced Gas Reactors (AGR), which employs CO2 as the coolant. The other one is a First of a Kind Engineering (FOAKE) PBMR, which uses Helium as the coolant. Both AGR and PBMR have complicated heat structure material in the core as moderators. The discussions include two PBMR design variations: a Demonstration Power Plant at 400 MWth (DPP400) and a Steam Power Cycle System (SPCS) 4 at 250 MWth. The SPCS as described here represents a class of options. Final design parameters and layout of the SPCS system is still under design. The revised Jtopmeret? 5 can be used as an engineering grade Thermal-hydraulic model for full scope gas cooled reactors.
