SHIELDING COMPUTER PROGRAM 04-1, REACTOR SHIELD ANALYSIS
Shielding Computer Program 04-1 is available for computing reactor- shield weight and fast neutron and gamma ray dose rates in and around complex reactor-shield assemblies. Reactor and shleld geometries are described by combinations of regions formed by rotating rectangles or trapezoids about the reactor axis or by translating rectangles parallel to the reactor axis. Compositions are expressed as volume fractions for each material in the reactor- shield assembly. A rectangular coordinate system is used to describe the location and dimensions of volume, surface, line, or point sources. Source densities are described by tables containing values ior each of the source region nodal points. A modification of the AlbertWelton theory of neutron attenuation is used for fast neutron dose rate calculations. Combination of buildup factors by empirical expressions is used with exponential attenuation to compute gamma ray dose rates. The program uses two magnetic tape units and eight frames of magnetic core memory on an IBM-704. Magnetic drum memory is not required. (auth)
