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.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

High-energy transport codes for the design of accelerator-driven systems such as the Spallation Neutron Source use nuclear reaction models as the incident particle, and the secondary particles are transported through various materials. These reaction models are computationally fast but are unreliable at energies below ~200 MeV. As a partial remedy, an evaluated cross-section library up to 150 MeV known as LA150 was developed by international cooperation and made available for such design work. In the present project we have been developing a model code suitable for improving LA150 and extending it to higher energies. This new model code combines microscopically the semiclassical results of an intranuclear-cascade model with the spin-dependent counterparts of a preequilibrium Hauser-Feshbach model. To achieve this microscopic combination, an approximation, explained in this paper, is needed to add spin distributions to the semiclassical excitation spectra in every residual nuclide. The initial capability of this code is demonstrated by comparisons with experimental production cross sections of the radioisotopes 56Co, 55Co, 54Mn, 52Mn, 52Fe, 51Cr, 48Cr, 48V, 47Sc, and 46Sc induced by proton projectiles on Fe from reaction thresholds to 3 GeV. The overall agreement of our calculated results with experimental data looks very good in view of the 29 contributions in recent model code intercomparisons with measurements.
