Title: SHIELDING COMPUTING PROGRAM 20-0

Technical Report ·
OSTI ID:4834952

Program 20-0 was developed to generate and write on tape source-particle parameters to be used as input for Monte Carlo shield program 18-0 designed for analysis of reactor-shield assemblies of interest to GE-ANPD. Source particles are generated in source tubes defined by right circular cylinders with mutually parallel axes of symmetry. A special case arises when the entire reactor is treated as a single source tube. The case of a point source can also be handled. Source particle spatial coordicates are chosen from appropriate power and power density distributions by one of two methods; a random method based on uniformly distrinuted random numbers, and a systematic method that determines the number of source particles to be started from specified volume elements. The systematic method is the only method that can be used for the special case of a single source tube. The energy of each source particle is chosen by a random method from an energy spectral distribution that is space dependent. Provision is made in the program for splitting on region and energy to conform to the demands of Program 18-0. Program 20-0 ls coded for use on an IBM-704 havlng 32,768 magnetic core memory locations. Five magnetic tape units are used by the program. (auth)
