SCALE: a modular code system for performing standardized computer analyses for licensing evaluation

This manual provides documentation for a new, multi faceted computational system called SCALE (Standardized Computer Analyses for Licensing Evaluation) that has been developed to provide a standard analysis tool for use by the NRC staff and licensees in evaluating nuclear fuel facility and package designs. The SCALE system consists of several automated analytical sequences (control modules) which perform criticality, shielding, and/or heat transfer calculations with a minimum of user-required input. The computer codes (functional modules) used within each analytical sequence can also be run in a stand-alone fashion or coupled together in a sequence determined by the user. Volume 2 contains documentations for the following functional modules used in the SCALE system: KENO-V which is an improved Monte Carlo criticality program; and JUNEBUG, a three-dimensional geometry plotting code
