A Three Dimensional Two Energy Group Coupled Reactor Physics and Thermal Hydraulics Code (M32) - A Tool for Student Design Studies

This paper describes a new code M32 that has been developed to perform coupled reactor physics and thermal hydraulic calculations undertaken in student reactor design studies. M32 is a general three-dimensional, two-energy group code that couples a diffusion theory representation of the core with a thermal hydraulic description that accounts for the heat flux and coolant enthalpy rise. A sample a pplication examining the feasibility of a high temperature helium cooled reactor based on the General Atomics GT-MHR design for marine applications is described. M32 has been demonstrated to be a useful addition to the portfolio of computational tools for education and training in reactor design methodologies.
