Lumped Parameter Dynamic Model of 10 MW High-Temperature Gas-Cooled Reactor

Based on the fundamental conservation of mass, energy and momentum, a mathematical dynamic model of the 10 MW High-Temperature Gas-Cooled Reactor (HTR-10) was developed. The reactor was nodalized to a lot of sections which were lumped to display uniform thermal-hydraulic properties. The point kinetics equations with six precursor groups of delayed neutrons were coupled to the developed model. The transient simulation result shows that the model developed is effective to simulate the reactor dynamics.
