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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

An in-situ tritium-deuterium gas-purification system has been constructed to produce a high-purity D-T target gas for muon catalyzed fusion experiments at the RIKEN-RAL Muon Facility. At the experiment site, the system enables us to purify the D-T target gas by removing 3He component, to adjust the D/T gas mixing ratio and to measure the hydrogen isotope components. The system is specially designed to handle the D-T gas with a negative pressure, and the maximum tritium inventory of 56 TBq (1500 Ci) is operated. The employed combination of a palladium filter and a cryotrap has demonstrated as an efficient device to purify hydrogen gas with a negative pressure. We have completed a series of muon catalyzed d-t fusion experiments at various tritium concentrations, including an experiment with a non-equilibrium D2-T2 target condition. The muon catalyzed t-t fusion process has also been studied using the tritium gas supplied free of 3He by the system.
