Abstract

China Advanced Research Reactor introduced the first critical test of the theory, methods and procedures. Without reference to the heap, not the physical simulation of zero-power case, the main advantage of numerical methods to simulate the first critical analysis of the experiment, the number of fuel assemblies have been extrapolated and the control gate height Bang Bang simulation curve extrapolated data to predict the critical number of fuel assemblies and critical rod gate height. Critical for the upcoming first experiment provides the necessary reference data. The theory and method of China Advanced Research Reactor first critical experiment were briefly introduced. Without referenced reactor and zero-power device, the theoretical calculation was used to simulate the whole process of CARR first critical experiment. The simulative extrapolate graph of fuel assembly number and control rods height were given, which predicted the critical fuel number and control rod height. This work provides necessary referenced data for the first critical experiment which will be carried out soon
