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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

The dehydriding reaction between ZrCo and hydrogen is the most important role of delivering hydrogen isotopes for fusion energies. Many researchers experimented in various conditions and estimated the relationship between ZrCo and hydrogen. In this study the kinetic approaches are performed using numerical simulations between ZrCo and hydrogen. Two kinds of parameter estimations are performed for the equilibrium pressure and the kinetics modeling and those are validated by the good agreement between predicted and experimental data. Based on the numerical simulation with obtained parameters, more rapid rates of dehydriding reaction can be achieved with lower pressure and higher temperature.
