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.

Neutral beam attenuation has been investigated by the beam emission diagnostic system at LHD which consists of a quartz optical fiber, leading to a spectrometer and an ICCD detector. The spectral resolution and the reciprocal dispersion are 0.21 nm and 1.4 nm/mm, respectively. The behavior of the beam-stopping cross-section derived from the beam emission is consistent with that of the cross-section from the Atomic Data and Analysis Structure (ADAS) database. The intensity of the beam emission decreases with increasing stopping cross-section from the use of heavy ions in a discharge. We have also observed that the measured cross-section of the hydrogen is larger than that of the ADAS calculation.
