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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

In order to investigate working characteristics of traveling wave direct energy converter (TWDEC) to flux with wide energy spread, the second-phase experiments of the research project using end-loss flux of GAMMA 10 were performed. The end-loss flux of the normal operation and that of the one-side plugging operation of GAMMA 10 were introduced to a bias-type TWDEC. The variation of effect of TWDEC operation was examined on relative phase difference between the modulator and the decelerator voltages. Both deceleration and acceleration effect were found according to the relative phase difference for the end-loss flux of both normal and one-side plugging operations.
