ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

The ADREA-I code is a three-dimensional transient analytical tool that can provide atmospheric boundary layer and dispersion analysis at the mesoscale and microscale levels, under any atmospheric stability conditions and with any ground complexity, and it is particularly suitable for large topographical disturbances and consequently large atmospheric altitudes. The code, in response to the need to treat large topographical disturbances with the highest spatial and temporal numerical resolution possible, introduces new features in the description of anomalous topography, turbulent diffusion coefficients, and numerical approach. Applications carried out within the framework of validation and demonstration studies of ADREA-I give reasonable results.
