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.

In order to make proof of the recovery of hydrogen isotopes from a liquid lithium (Li) blanket, we experimented the recovery of deuterium (D) dissolved in Li by means of yttrium (Y) metal at 300°C. In the experiment, 160 wppm D dissolved in Li was removed down to 1 wppm by means of the Y trap maintained at 300°C under fluidized Li conditions. The ratio of the final-state D concentration dissolved in Li to the initial one is defined as a removal efficiency, and the removal efficiency was found to be in proportion to the D concentration remained in Li. In addition, judging from its dependence on D concentration remained in Li, it was found that the removal efficiency is well consistent with the secondary-order reaction process and the removal efficiency was correlated to a function of contact time.
