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.

The possibility of obtaining ignition in the Tokamak Fusion Test Reactor (TFTR) by means of very centrally peaked density profiles is examined. It is shown that local central alpha heating can be made to exceed local central energy losses (“central ignition”) under global conditions for which Q 1. Time-dependent one-dimensional transport simulations with a simplified transport model show that the normal global ignition requirements are substantially relaxed for plasmas with peaked density profiles. More realistic simulations with recently developed profile-consistent microinstability based models for electron and ion confinement show that TFTR may form a small centrally ignited region if peaked central density can be maintained.
