SPAR1; shielding with analytic ray-tracing. [CDC6600,7600; FORTRAN IV]

Technical Report ·
OSTI ID:6232834
SPAR1 calculates exact gamma-ray fluxes from uniform sources with the shapes of slabs, disks, lines, cylinders, truncated cones, toroids, and spheres. Gamma-ray dose rates and energy absorption rates can also be obtained by including in the program input data gamma-ray buildup factors expressed in Taylor Exponential Coefficient form. Furthermore, SPAR1 will calculate fast-neutron dose rates and thermal-neutron fluxes in those cases where the use of neutron-removal cross sections is valid. In general, all three-dimensional sources having curved surfaces (cylinders, spheres, and toroids) may have both curved and slab shields intervening between the source and the detector point. Slab shields are allowed in all cases. Both slab and curved shields are assumed to be laminar. Source self-attenuation is always included in flux calculations, and multiple energy levels may be considered. Both interior and exterior detector points are allowed for cylindrical, slab, and spherical sources, and line sources may be tilted with respect to their slab shields. The detector point associated with a cylindrical volume source may be arbitrarily located, and a finite cylindrical shield may be considered. A cylindrical surface source is also available.CDC6600,7600; FORTRAN IV; SCOPE 3.1 (CDC6600); 50K central memory and one system disk (CDC6600).
