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.

A method for joining Zircaloy-2 with stainless steel, using controlled expansion transition sections, is described. The transition sections consist of nickel-iron elements of the Invar type and range from low expansion rate 43% nickel-iron, at the Zircaloy-2 end, to high expansion rate 60% nickel-iron, at the stainless steel end. Problems encountered in producing suitable mechanical joints between Zircaloy-2 and 43 % nickel-iron and in preparing and welding the various grades of nickel-iron to each other and to stainless steel are discussed.
