Title: CRRIS: a computerized system to assess atmospheric radionuclide releases

Journal Article · · Nucl. Saf.; (United States)
OSTI ID:6896527

The Computerized Radiological Risk Investigation System (CRRIS) consists of six integrated computer codes that stand alone or are run as a system to calculate environmental transport, doses, and risks from atmospheric radionuclide releases. PRIMUS output provides to other CRRIS codes the capability to handle radionuclide decay chains. ANEMOS and RETADD-II calculate atmospheric dispersion for local (less than or equal to 80 km) and regional (> 80 km) distances, respectively, and output annual-average air concentrations and ground deposition rates. Multiple ANEMOS Runs for sources within a small area are combined on a master grid by SUMIT. TERRA calculates food-chain transport, and ANDROS calculates individual or population exposures, doses, and risks. Integral to CRRIS are computerized upper-air wind, climatological, agricultural, land use, demographic, decay, and dosimetric data bases. It is expected that CRRIS may be used by the Environmental Protection Agency in determining compliance with the Clean Air Act for radionuclides released from Department of Energy facilities and facilities licensed by the Nuclear Regulatory Commission.
