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 fuel management scheme is proposed for a twofold purpose: incineration of light water reactor waste plutonium and electricity generation. The scheme is based on a fast spectrum core with lead as a coolant. The core is managed in a three-batch mode, 200 days per cycle. Enriched 10B, in B4C pellets, is used as burnable poison, reducing the criticality drop to just 2.8%/cycle. The latter can be handled easily with a few control rods. The core is flat, with a 400-cm diameter and 90-cm height, to ensure that core voiding results in a criticality decrease. Recycled fuel is recharged into the core after the fission products, but not actinides, have been removed. Equilibrium operation is reached within a short period of 2 yr. In a span of 27 yr, the core will incinerate the plutonium at an average rate of 730 kg/yr, while generating 1000 MW(electric).
