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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

A new experimental method has been used to determine the isomeric ratio (IR) in neutron capture of 241Am in a differential experiment. Thin 241Am samples have been activated with subthermal monoenergetic neutrons of 14.75 meV and quasi-monoenergetic neutrons of ∼30 keV. The decay of the 242Am nuclei produced has been determined by observing the emitted beta spectrum in a mini-orange spectrometer. The measurements have been performed relative to gold. The ratio R1 = σγ (241Am→ 242gAm)/σγ(Au) was found to be R1 = 5.79 ± 0.33 at 14.75 meV and R1 = 2.73 ± 0.16 at ∼30 keV. The corresponding IRs, σγ(241Am→ 242gAm)/σγ(Am), are 0.92. ± 0.06 at 14.75 meV and 0.65 ± 0.05 at ∼30 keV. Detailed theoretical calculations of the total capture cross section, the IR, and the capture gamma-ray spectra were performed in the energy range from 1 to 1000 keV taking advantage of recently available information on the discrete level scheme of 242Am. With the present knowledge on the level scheme of 242Am, it seems to be difficult to reproduce the strong energy dependence of IR as indicated by the experimental results.
