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.

A tritium imaging plate technique (TIPT) was used to measure the hydrogen solubility and diffusivity of a proton-conducting material, Zr-doped BaInO2.5. After being exposured to tritiated water vapor, the specimen was cut into halves and photo-stimulated luminescence (PSL) images of the cross-section of the cut specimen were obtained. Based on the PSL distribution profiles and intensities, hydrogen diffusivity and solubility in the specimens were determined. The hydrogen solubility and diffusivity in Zr-doped BaInO2.5 clearly depended on the content of Zr. This characteristic of the Zr content is in agreement with the Zr-content dependency of its proton conductivity, which was measured by an alternating current (AC) impedance method.
