A group condensation program was developed to take a multigroup cross- section library in the format suitable for the Carlson DSN/TDC neutron transport theory programs and produce a similar multigroup library with a reduced number of groups. The energy groups of the original library were combined together without splitting to give the required new energy groups. Weighting spectra were given for averaging cross sections. The program was designed to fit into the Carlson programs so that, when suitable, a standard multigroup library can be used as input although a much reduced liorary is used for the calculation. lf required, the program can be used separately to produce a printed record and/or a punched set of cross sections. The machine space required is approximately 13008 instructions plus the space required by the original library. The program was not designed to apply to cases with anisotropic scattering. (auth)
