Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

Until the recent experimental campaign in 2006, all the neutral beam systems on the DIII-D tokamak injected power with the momentum in the same direction as the usual plasma current ("co-injection"). A major modification made during the April 2005-March 2006 shutdown period rotated one of the two-source beamlines to allow injecting power with the momentum opposite that of the plasma current ("counter-injection"). This modification provides the capability of injecting up to 10 MW of neutral beam power with zero net momentum input to the plasma. Decoupling the injected momentum and power opens a previously inaccessible parameter space for experiments that study the effect of rotation on various plasma instabilities, transport, and operational scenarios.Rotating the 5 MW neutral beamline presented significant technical challenges. The beamline and several major subsystems required extensive dismantling and rebuilding, and a careful alignment of the ion sources was required to document the new injection paths. We present a summary of the tasks required for the beamline rotation, describe major technical issues addressed, and discuss the advantages of the new configuration.
