Numerical heat transfer in cylindrical nuclear reactor with reflected layer

The physical properties and the thermal properties of the cylindrical nuclear power reactors with reflected layer(in radical direction,in axial direction and totally reflected) were computed by the finite volume method(FVM) using the unstructured meshes and structured meshes.Firstly,the thermal neutron flux of the core and the reflector were computed by One-group method,the numerical solutions were compared with the exact solutions.The computational results indicated that each other's method have a good credibility,then the same method was used to confirm the temperature distributions in the two section,and the numerical solutions of the thermal power was computed.All results for the reflected reactor were compared with those for bare reactor and these can provide a useful reference for the nuclear engineering design and research.
