Computer Simulation of Radiation Effects in Zircon
EMSL Project ID
3534a
Abstract
Zircon is an extremely durable mineral proposed as a crystalline host for the disposal of high actinide waste forms. In order to minimize the release of actinides to the environment, it is essential to understand the production of defects by radiation, the subsequent migration of these defects, and basic diffusion mechanisms in zircon. In order to obtain such an understanding, molecular dynamics computer simulations employing nearly a million atoms are needed. These simulations will help in the interpretation of experimental results and in tailoring the waste isolation hosts to minimize actinide release.
