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.

NEA issues call to action in report on nuclear cost reductions
A new report from the Paris-based OECD Nuclear Energy Agency declares that nuclear power is needed for countries to meet their Paris Agreement decarbonization and energy security policy goals, but that governmental support for a rapid reduction in the cost of new nuclear capacity through the creation of certain policy frameworks is likely necessary.

The characteristics of a two–radio-frequency (RF)–driven dual antenna inductively coupled hydrogen plasma is investigated for the development of a high efficient RF negative hydrogen ion source driver. The two-RF-driven dual antenna system consists of a 2 MHz–driven solenoidal antenna wound around a cylindrical chamber and a 13.56 MHz–driven planar antenna placed on top of it. Compared to the conventional single frequency antenna inductively coupled plasmas, the two-RF-driven dual antenna inductively coupled plasma reveals two distinctive features, i.e., an increase in the power transfer efficiency and the bi-Maxwellization of the electron energy distribution function due to the collisionless heating. These characteristics allow the two-RF-driven dual antenna inductively coupled plasma to accomplish enhanced generation of negative ions and their precursors with a high RF efficiency.
