Abstract
The code COSMOS-3 has been developed at Chalk River Laboratories as part of the safety assessment methodology for the disposal of low-level radioactive waste (LLRW). Radiation dose equivalents as a consequence of the escape and migration of radionuclei from near surface disposal facilities are predicted. This report describes the features available in the present Version 3 of COSMOS. The physical processes represented by each major submodel are described, with references to other documents containing more details. Changes in the vault model of an earlier version of COSMOS resulting in version 3, including a change in emphasis from nuclide concentration to nuclide flux as the simulation variable, have provided an improved ability to model the behavior of the engineered system of the disposal facility. As a consequence of increased computer time necessary for such modelling, however, the use of COSMOS-3 as a stochastic or probabilistic systems assessment code is limited.
