GAO: Grouting Hanford tank waste could cost more than $1.1B

Grouting Hanford’s low-level radioactive liquid tank waste could cost between $480 million and $1.1 billion, according to a report by the Government Accountability Office, which has repeatedly found that grouting (immobilizing waste in a concrete-like mixture) can accelerate cleanup at the Hanford Site and save billions of dollars when compared to mixing the waste with molten glass through the vitrification process.

The Current Issues in Computational Methods Roundtable will present five researchers who will give talks on several aspects of upcoming developments and challenges in code development and entertain audience questions. Points of emphasis will be the opportunities and demands of new machine architectures for Monte Carlo and Deterministic transport, applications of AI to high energy density science, and computational challenges for the nuclear sector. Speakers and titles: Erin Davis (LANL) "PARTISN: Enabling a 20th century Fortran transport code to meet 21st century" Kelli Humbird (LLNL) “Cognitive simulations for inertial confinement fusion” Alicia Klinvex (NNL) “Accelerating Transport Codes on Newer Architectures” Rachel Slaybaugh (UCB) “Optimal Operations of Advanced Reactors: how do we get there?” John Tramm (ANL) "More than a port: challenges in GPU-based MC and MOC particle transport"
