SCAP; point kernel single or albedo scatter. [CDC7600,CYBER175; FORTRAN (99%) and COMPASS (1%)]
SCAP solves for radiation transport in complex geometries using the single- or albedo-scatter point kernel method. The program is designed to calculate the neutron or gamma-ray radiation level at detector points located within or outside a complex radiation scatter source geometry or a user-specified discrete scattering volume. The geometry is described by zones bounded by intersecting quadratic surfaces with an arbitrary maximum number of boundary surfaces per zone. The anisotropic point sources are described as point-wise energy dependent distributions of polar angles on a meridian; isotropic point sources may be specified also. The attenuation function for gamma rays is an exponential function on the primary source leg and the scatter leg with a buildup factor approximation to account for multiple scatter on the scatter leg. The neutron attenuation function is an exponential function using neutron removal cross sections on the primary source leg and scatter leg. Line or volumetric sources can be represented as distributions of isotropic point sources, with uncollided line-of-sight attenuation and buildup calculated between each source point and the detector point.CDC7600,CYBER175; FORTRAN (99%) and COMPASS (1%); SCOPE 2.1 (CDC7600), NOS 1.3 (CDC CYBER175); 55,000 (octal) words of memory are needed to execute the SCAP program on the CDC CYBER175.

- Resource Relation:
- Other Information: The geometric zone description is restricted to zones defined by boundary surfaces defined by the general quadratic equation or one of its degenerate forms. Due to flexible dimensioning in SCAP, there are no restrictions on the number of energy groups or geometric zones
