3. DESCRIPTION OF PROBLEM OR FUNCTION - ADENA calculates approximately fission-product beta and gamma decay energies and spectra in 19 or fewer energy groups from a mixture of U-235 and Pu-239 fuels. The calculation uses aggregate, adjusted data derived from a combination of several experiments and summation results based on the ENDF/B-V fission product file.


4. METHOD OF SOLUTION - An absorption correction for U-235 and Pu-239 fuel mixtures is applied in the spectra calculation. The energies are calculated for finite, user-defined irradiation times. For long irradiation times, the effect of neutron absorption is accounted for.
