Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

More and more, soft or hard magnetic materials have been used in the magnetic confinement fusion machine, like reduced-activation ferritic-martensitic steel, which may be used in the first wall and breeding blanket structural material of ITER. Twisted coils in the stellarator may be substituted by permanent magnets. ANSYS electromagnetic simulation has two methods: nodal-based formulation or edge-based formulation. Nodal-based formulation has been widely used in past years. This paper will present a modification to the nodal-based element SOLID97 in ANSYS to form the correct normal boundary condition to model ferromagnetic materials and compare the results, e.g., field, eddy current density, and Lorentz force, to edge-based methods using SOLID236.
