ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

Experimental researches of the shear flows influence on the confinement in the mirror trap of the dense nonequilibrium helium and nitrogen plasma created under conditions of the electron cyclotron resonance (ECR) gas breakdown were made.Limiter with electric potential relative to the vacuum chamber was set inside the mirror trap.During the increasing of the value of limiter potential over Ucrit = 70-100 V the considerable increasing of the full ion flux from the trap was obtained (about of 3-4 times) that is apparently indicates that the plasma density and may be electron temperature increased in the trap that can be interpreted as the transversal losses decrease that is the result of “vortex confinement” regime realization. Pointed effect was obtained in the helium and nitrogen plasma both. Azimuthal modes with m = 1, m = 2 dominated in spatial spectrum of plasma oscillations.This method of “vortex confinement” regime realization for non-equilibrium heavy ions plasmas seems to be perspective for new generation of ECR heavy multicharged ion sources creation.
