KENO2; KENO4; Monte Carlo multigroup criticality code. [IBM360; CDC6600; FORTRAN IV and Assembly language (IBM360), FTN FORTRAN with COMPASS subroutine (CDC6600)]
KENO is a multigroup, Monte Carlo criticality code containing a special geometry package which allows easy description of systems composed of cylinders, spheres, and cuboids (rectangular parallelepipeds) arranged in any order with only one restriction. Each geometrical region must be described as completely enclosing all regions interior to it. For systems not describable using this special geometry package, the program can use the generalized geometry package (GEOM) developed for the O5R Monte Carlo code. It allows any system that can be described by a collection of planes and/or quadratic surfaces, arbitrarily oriented and intersecting in arbitrary fashion. Rectangular arrays of fissile units are allowed with or without external reflector regions. Output from KENO consists of keff for the system plus an estimate of its standard deviation and the leakage, absorption, and fissions for each energy group plus the totals for all groups. Flux as a function of energy group and region and fission densities as a function of region are optional output.IBM360;CDC6600; FORTRAN IV and Assembly language (IBM360), FTN FORTRAN with COMPASS subroutine (CDC6600); OS/360 (IBM360) and SCOPE 3.3 (CDC6600); The CDC6600 program requires 64K words of fast core, a disk facility or one or more tape units. The IBM360 version of KENO2 requires approximately 64K words of fast core, a disk facility or one or more tape units. The IBM360 version of KENO4 requires 1 to 6 scratch units besides the standard input/output units and a minimum of about 200K core.
