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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

A sevenfold integral expression is derived for the absorbed dose rate from the uncollided flux of gamma rays at the center of a spherical shell shield bombarded by an omnidirectional flux spectrum of protons. The general formulation is reduced to a fourfold integral on the basis of simplifying assumptions. This simpler formulation assumes that the gamma rays are produced isotropically by an isotropic proton flux, that protons penetrating the shell are not deflected from their original direction of incidence, that the spectrum and yield of photons are independent of proton bombarding energy, and that both the incident proton spectrum and the range-energy relation for protons in matter have power-law representations. A sixfold intergral expression is derived for the absorbed dose rate from the once-collided flux of gamma rays at the center of a spherical shell shield bombarded by an isotropic flux spectrum of protons. The once-collided differential (in energy) flux of photons at the shell center is given by a fivefold integral expression.
