FIGRO is a FORTRAN-IV program for the analysis of fuel volume swelling and the calculation of temperatures in bulk-oxide cylindrical fuel elements. The fuel pellet may be solid, annular, or contain two radial zones. Oxide fuel thermal conductivity is a function of temperature, depletion, and porosity; fuel swelling is a function of temperature, depletion, internal hydrostatic pressure, and fissioning rate. As a boundary condition for the heat conduction equation, either the clad surface flux or the temperature at the inside radius of the fuel may be specified. Two sample problems are presented as test cases for the program deck and to exhibit the features of the input and output. (NSA 21: 14116)
