3.
DESCRIPTION OF PROGRAM OR FUNCTION - CHAINS computes the atom density of members of a single radioactive decay chain. The linearity of the Bateman equations allows tracing of interconnecting chains by manually accumulating results from separate calculations of single chains. Re-entrant loops can be treated as extensions of a single chain. Losses from the chain are also tallied.
4.
METHOD OF SOLUTION - The Bateman equations are solved analytically using double-precision arithmetic. Poles are avoided by small alterations of the loss terms. Multigroup fluxes, cross sections, and self-shielding factors entered as input are used to compute the effective specific reaction rates. The atom densities are computed at any specified times.
5.
RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Maxima of 100 energy groups, 100 time values, 50 members in a chain.
6.
TYPICAL RUNNING TIME - RSIC executed the sample problem in 2 seconds on a PC 486, running 33 Megahertz.
