RICE - a reactor inventory code for calculating actinide and fission product arising using a point source model

The computer code RICE, which can be used to calculate the actinide and/or fission product inventories of irradiated nuclear fuel, is described. The range of actinide and fission product isotopes considered is large enough to permit studies to be made of the effect of decades-long irradiations and of geological cooling times. The actinide and fission product inventories are calculated for burnup periods using numerical methods best suited to each problem while analytical solutions are used for cooling periods. The code can be used to perform a coupled actinide-fission product calculation, a solely actinide calculation or a solely fission product calculation. Output consists of inventories, activities, biological hazards, decay heating, γ spectra and macroscopic cross-sections, among others. A brief description is also given of previous work in this field. (author)
