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.

The Cs2LiYCl6:Ce3+ (CLYC) scintillator is being widely employed in nuclear physics, planetary science, radiation environmental monitoring, nuclear security, and nonproliferation communities. The time resolution of a 1 × 1-in. CLYC scintillation detector is reported in this paper. It was measured by the use of a high sampling rate DRS4 waveform digitizer and an EJ-309 liquid scintillation detector. The digitizer was first characterized with regard to its intrinsic time resolution and then the time resolution of the EJ-309 detector was investigated. It served as a reference detector in the time resolution measurements for the CLYC detector. The time pick-off techniques used were the constant fraction discrimination and leading edge discrimination methods. In addition, the Savitzky-Golay filter was used to further improve the measured time resolutions. This filter was shown to be an effective approach to improving time resolution when the signal-to-noise ratio is low.
