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.

A laser fusion reactor needs an optical mirror in its final optical system. This optical mirror is exposed to the neutron produced with fusion reaction. It is pointed out that the exposure to neutron will produce hydrogen gas in the mirror and cause swelling deformation of mirror. To avoid this swelling of mirror, a liquid-metal mirror is promising. High energy laser shots on the liquid mirror will cause the surface wave. These waves must be damped to under 1/10 of the laser wavelength in 250 ms or less. In this study, the hydrodynamic behavior of the liquid surface was investigated by experiment with water as surrogate liquid, the computational evaluation for the wave propagation with the MARS (Multi-interface Advection and Reconstruction Solver, 2001) was carried out, and the design window for the optical mirror based on the water experiment was discussed.
