User's guide for GENII-S: A code for statistical and deterministic simulations of radiation doses to humans from radionuclides in the environment.

摘要

This document describes the GENII-S computer code and is intended to provide the reader with enough information to use the code. GENII-S was developed to use in performance assessment for the Waste Isolation Pilot Plant at Sandia National Laboratories. GENII-S is a successor to a Pacific Northwest Laboratories code, GENII. GENII was developed to estimate potential radiation doses to humans from radionuclides in the environment. The GENII code addresses both routine and accidental releases of radionuclides to air or water as well as other situations, (e.g., residual contamination from spills or decommissioning operations). The GENII code was incorporated into the SUNS software shell at Sandia National Laboratories to form GENII-S. Implementation into SUNS gives the user the capability to perform sensitivity and uncertainty analyses in one calculation, eliminating manual interfaces between the GENII code results and the sensitivity and uncertainty analysis codes. It provides a larger degree of quality assurance and a user-friendly, menu-driven interface for input and output processing.
