RSAC VERSION 7

The Radiological Safety Analysis Computer (RSAC) Program Version 7.0 (RSAC-7) is the newest version in RSAC legacy, RSAC 7.2 is the current release. RSAC-7 combines a user friendly interface with a powerful analysis tool. It calculates the dose consequences of a release of radionuclides to the atmosphere. Using a personal computer, a user can generate a fission product inventory from either reactor operating history or a nuclear criticality event. RSAC 7 includes the dose conversion factors from ICRP 68 and ICRP 72. In addition, it includes the analysis tool and conversion factors for generating a 24-hour acute organ dose. Joint frequency meteorological analysis combined with a summary of 50% and 95% conditions allow for an easy check or analysis of the sensitivity of met conditions. Each of its nine subroutines performs a type of calculation and operates together with or independently of the others, depending on the analysis being performed.

RSAC-7 models the effects of high-efficiency particulate air filters or other cleanup systems and calculates the decay and in-growth during transport through processes, facilities, and the environment. Doses are calculated for resuspension, inhalation, air immersion, ground surface, ingestion, and cloud gamma pathways. RSAC-7 can be used as a tool to evaluate accident conditions in emergency response scenarios, radiological sabotage events and to evaluate safety basis accident consequences. It has an internal validation process to assure proper verification of installation parameters. RSAC-7 allows curies, grams, and Becquerel units to be input into the direct input model.

RSAC-7 is fully verified and validated per NQA-1 2000 for Quality Level 1 applications. It has been proposed for inclusion in the Safety Software Toolbox. RSAC-7 can be used as either the primary or secondary dose consequence analysis tool.
