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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

A pelletizing mechanism was studied theoretically and experimentally to transform radioactive waste powders into dense and hard pellets in conjunction with the development of a new volume reduction system, a drying and pelletizing system. A pelletizing model was proposed based on plastic deformation of powder particles. Its validity was confirmed by fundamental experiments. From the model, such pellet properties as density and strength can be predicted over a wide compacting pressure range of a pelletizer using one material constant, the shear modulus of the powder, and one experimental value. This led to the proposal of a method to control the pelletizer and to estimate pellet properties. Usefulness of the method was confirmed experimentally from pilot plant tests.
