ICONE23-1216 Simulation on Reactor Boron and Water Makeup System based on GSE

Abstract

Reactor Boron and Water Makeup System (REA) is one of the most important auxiliary systems of PWR nuclear power plant, whose normal operating modes involve auto-filling, manual-filling, rapid dilution, slow-footed dilution and boronization. The realtime simulation on REA fluid network with high accuracy can be used to train operators. The analysis of dynamic response simulation results can provide theoretical basis for REA design and control strategy optimization. GSE Systems, Inc. is a great simulation platform, which develops and markets software-based simulation and training products. Jtopmeret is the two - phase dynamic simulation tool of GSE, which provides the graphics modeling simulation industry with high fidelity dynamic models. Moreover, models can be developed and improved manually using Compaq Visual Fortran language on the GSE platform. In this paper, we introduce the function, composition, operating conditions and control theories of REA. Furthermore, the REA model of Daya Bay nuclear power plant is built using Jtopmeret and FORTRAN language. The results indicate that the steady errors of the main parameters are less than 2% under design conditions, which verifies the availability and reliability of GSE and Jtopmeret. The dynamic response results are reasonable under various transient operating conditions.
