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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Polystyrene and poly(α–methylstyrene) (PAMS) shells made by microencapsulation are prone to having vacuoles in the walls and a concommitant surface roughness. These defects can be detrimental to the implosion required for ICF shots. We have found that adding sufficient salt (typically CaCl2 or NH4Cl) to the exterior polyvinylalcohol (PVA) solution during the drying phase inhibits the formation of vacuoles and decreases the surface roughness of the shells. The use of such salts does affect other shell specifications, for which other process variables must be adjusted.
