Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

College students help develop waste measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

A Chinese dual-functional lithium lead test blanket module was proposed for testing in ITER. The flow channel insert (FCI) was inserted in LiPb flow channels to reduce magnetohydrodynamic (MHD) effects and to increase the outlet temperature of coolant LiPb. The FCI has a big influence on the LiPb flow characteristics under the high magnetic field. In this paper, the LiPb MHD flow characteristics both in the gap between the FCI and the channel wall and inside the FCI was numerically calculated using an MHD code named MTC-H 2.0 in a poloidal channel. The influence of the FCI on flow distribution was analyzed. The pressure drop was compared to the case without the FCI, and the pressure equalization was assessed for both sides of the FCI with pressure equalization openings. The impact of electrical conductivity of the FCI material was analyzed.
