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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Tungsten and tungsten carbide were damaged in ambient air with varying incident angles (0, 30, 45, and 60 deg) for approximately 5000 shots. The goal of these experiments was to observe the macroscopic surface modification in tungsten and tungsten carbide surfaces in harsh environments. At low pulse numbers (one to eight laser pulses on the same spot), tungsten aerial surface damage was less than tungsten carbide damage; however, at very high pulse numbers (5000), the opposite was true. Surface damage was mostly in the form of craters that were near circular at low impact angles and became more elongated at higher laser pulse impact angles. On the tungsten surface, a cluster of tungsten oxide debris formed. During laser exposure, laser-induced periodic surface structures and grooves were formed, and their geometries varied with laser intensity and laser impact angle. The period of laser-induced surface changes increased as the incident angle increased for both tungsten and tungsten carbide surfaces. More mass was lost in tungsten than tungsten carbide, which agrees with the morphological responses.
