Abstract
The tightly coupled solution of neutronics and thermal-hydraulics play an important role in precise simulation of fuel designs. Fully Ceramic Microencapsulated (FCM) fuel was one of the popular designs for accident tolerant fuel. To simulate advanced fuel types such as FCM fuel, a new method was proposed to couple the Monte Carlo code RMC with multi-physical software COMSOL. The MATLAB interface was adopted for coupling, and the superimposed structured mesh was applied to the mesh mapping and data interpolation between the structured meshes of RMC and unstructured meshes of COMSOL. Then the coupling code was verified by a typical PWR fuel rod and a FCM case. Results show that the calculated power and temperature distributions are reasonable, which can capture the self-shielding effect of thermal neutrons. Comparing with the traditional “cell-to-cell” mapping, the proposed method has advantages of good geometric flexibility and high accuracy, which can be applied to multi-physics simulations of different fuel designs.
