DOE-EM issues draft RFP for Hanford lab work, awards WIPP monitoring grant
The Department of Energy’s Office of Environmental Management issued a draft request for proposals on June 25 for the Hanford Site’s 222-S Laboratory contract. The 222-S Laboratory is the primary on-site laboratory for analysis of highly radioactive samples in support of all projects at the DOE’s Hanford Site in Washington state.

A simple, yet comprehensive, model of the divertor region is presented. The model is based on the two-point approach described by Galambos and Peng but has been enhanced to include the key processes of remote radiative cooling, neutral recycling, particle convection, ash effects, and the effects of divertor geometry and plate material. Neutral particle effects are represented using a wedge-shaped section of plasma overlying the divertor plate and a slab attenuation model. The results of benchmarking against four other divertor models demonstrate the applicability of the proposed model. System sensitivities to key parameters are discussed and several general observations regarding divertor design are presented.
