Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

This technical note describes the use of graphene as a way to protect plasma facing components from erosion, sputtering and diminished plasma performance and to extend component lifetimes in experimental plasma devices. In this work, 30 keV ionized helium is used as a projectile on graphene covered tungsten over a range of fluences. Graphene’s vacancy yield (ID) and natural resonance (IG) are found at ~1350 cm−1 and ~1550 cm−1, respectively. Damage of each sample is quantified using the ID/IG ratio via Raman spectroscopy (RS) at the aforementioned wave numbers. The surface morphology is studied using Scanning Electron Microscopy (SEM) and the mass losses are recorded using a high-precision scale. The results from this study are of considerable importance since they indicate that a graphene coating could be an effective candidate for reducing erosion in different PFC materials.
