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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The application in TEXTOR of an externally controlled radial electric field Er, imposed by means of an electrode, has allowed to ascertain many aspects of the physics of the creation of Er and of its effect on radial transport. Radial conductivity was shown to depend on parallel viscosity with the latter's nonlinear response to Er providing the basic ingredient for Er bifurcation, typical for L- to H-mode transitions. Simultaneous time and space resolved measurements of Er and of the plasma flows in the edge by means of a newly developed inclined Mach probe have allowed to further substantiate the role of parallel viscosity and of neutral collisions in the damping of rotation. The causal role of grad Er in bringing about the transport changes has been proven by showing that the field shear is spatially correlated with and temporally leads the density gradient, as well as by comparison with theoretical modeling.
