Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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 the case of a fire accident in a fusion plant, tritiated organic substances will be produced. We have developed a Pd/ZrO2 catalyst applicable for the oxidation of tritiated organic substances. In this study, two different weight ratios of palladium, 5 and 10 g/l, were selected. The overall reaction rate constant of tritiated methane oxidation with the palladium catalysts in a flow-through system were determined as a function of space velocity from 1200 to 7000 h-1 , methane concentration in carrier from 0.004 to 100 ppm, and temperature of catalyst from 323 to 673 K. As-received catalysts showed a large overall reaction rate constant over the whole tested temperature range. However, the constants gradually decreased after a while. The considerable decrease was evaluated especially over the lower temperature range. The decrease has been explained as caused by the layers of produced water that formed on the surface of the catalyst playing the role of obstacle to reactant transport onto the noble metal deposited on the catalyst. The performance of 10 g/l catalyst was superior to that of 5 g/l over the whole tested temperature range. The overall reaction rate constant was dependent on the space velocity and independent of methane concentration in the carrier.
