SPAN-3--A SHIELD DESIGN PROGRAM FOR THE PHILCO-2000 COMPUTER
Technical Report
·
OSTI ID:4796690
SPAN-3 is a shield design program which can be used to calculate fast neutron dose rate, thermal neutron flux, gamma ray flux and dose rate, and energy absorption rate in cylindrical geometry by integrating appropriate exponential kernels over a source distribution. These integrals are estimated by the method of Gauss quadrature. The shield configuration consists of a cylinder composed of annular shields and a contiguous slab region composed of semiinfinite, parallel, slab shields. Regions of integration are defined as sectbrs of annuli contained within a cylindrical sector over which the source is defined in the form S/sub 1/ (r,z)S/sub 2/( theta ). This program can be run only on a 32K Philco2000 computer. (auth)
