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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

A point-kinetics model is used to investigate the effect of the amount of auxiliary power and energy of the injected neutral beam on the dynamics of the International Thermonuclear Experimental Reactor (ITER). Four different confinement scalings are tried. A multigroup slowing-down method is followed to consider the finite thermalization time of the fusion fast alpha particles and the injected neutral beam particles. The analysis shows the ability of the reactor to approach a steady-state operation. An auxiliary heating scenario of 20 MW and 1.3 MeV neutral beam allows steady-state operation without violating the beta limit. The analysis also shows the sensitivity of the reactor dynamics to the confinement scaling. In addition, the analysis shows that the reactor power can be increased by increasing the rate of the injected fuel, but varying the energy of the injected fuel does not affect the reactor power.
