The IBM-704 program RE-147 is used to calculate the time and space- dependent temperature distribution in a solid cylindrical fuel pin, cooled on the surface, with internal heat generation. The fuel pin may be bare or clad, and its boundary may be cooled by either flowing or staagnat coolant. The heat generatlon source may also be time and space dependent. Specifically, the program considers the fuel pin to be composed of two regions and then solves, by the usual finite difference methods, the heat conduction partial differential equation in the two regions. Simultaneously, the axial and time variation of the coolant temperature is calculated by a finite difference approximate solution of the energy equation for the coolant. An approximate method is included to allow for the effects of solid-state phase changes. In conjunction with the phase- changing procedure, the material properties are permitted to vary from one phase to the next. (auth
