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.

Several emergency plasma shutdown schemes for the International Thermonuclear Experimental Reactor (ITER) have been analyzed. The development of these procedures is critical in order to demonstrate a reliable safety system to respond to accidents resulting from failures in burn control systems, plasma facing components, and thermal conversion facilities. The schemes considered include shutting off the heating and fueling systems, triggering an H-mode to L-mode transition, injecting impurities, and disabling vertical stability control systems. Most of these methods are based on active detection and intervention primarily because the power producing element (the plasma) is not in direct communication with the media undergoing the accident condition (the coolant and blanket material). Time dependent simulations indicate that emergency shutdown time without triggering a disruption from the above schemes is only marginally acceptable.
