FIGRO calculates the one-dimensional steady-state temperature distribution and total fuel swelling for metal-clad, axisymmetric, 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. Fuel-clad gap conductance is a function of gas composition, temperature, and gap thickness at operating conditions. Either the clad surface flux or the temperature at the inside radius of the fuel may be specified as a boundary condition for the heat conduction equation. Thermal expansion of the fuel and cladding is accounted for. Transient temperature calculations can then be performed starting from the steady-state solution with user-specified heat generation and water temperature tables.CDC6600; FORTRAN IV; SCOPE 3.1.
