After decades, Hanford’s WTP begins vitrifying tank waste
The Department of Energy’s Office of Environmental Management and its contractor Bechtel announced on October 15 the start of nuclear vitrification operations at the Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant, at the Hanford Site in Washington state.

Using a central-force model, with experimentally determined force constants, the lattice vibrational spectrum of beryllium has been determined from a sampling of 2413 points in the first Brillouin zone. The specific heat derived from this spectrum agrees well with measured values. This vibrational spectrum has been used to compute the inelastic scattering of slow neutrons from beryllium in the incoherent approximation. Agreement with experiment is good in the region of high momentum transfer where this approximation applies. The coherent elastic scattering depends on the vibrational spectrum, and this has also been computed.
