Abstract

Verification calculations were performed to provide assurance that the MILDOS-AREA computer code is performing its calculations as intended, that is, the models are properly implemented in the code. MILDOS-AREA is used to estimate the radiological impacts from airborne emissions from uranium milling facilities. It provides the capability to consider both conventional uranium ore operations and operations associated with in situ recovery facilities. The code is used by license applicants and U.S. Nuclear Regulatory Commission staff to perform routine radiological impact estimates for the licensing of various uranium recovery operations. Independent verification of the calculations was performed external to the computer code in spreadsheets using Microsoft Excel®. All major portions of the code were investigated. The verification was conducted on a step-by-step basis and used five sample test cases as templates. Calculations were performed to verify the reported radionuclide release rates, air dispersion results, environmental media concentrations, and human exposure doses.
