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.

Differential cross sections have been measured at the University of Lowell for the ground and first two excited states of 232Th via the neutron time-of-flight technique. The following results are presented for neutron scattering cross sections: (a) excitation functions of 232Th in the incident energy range from 185 to 2400 keV for the 0+ ground state and the 2+, 49-keV state, and in the 480-to 2400-keV range for the 4+, 162-keV state; (b) angular distributions for the 0+ and 2+ states at 185 keV and for the 0+, 2+, and 4+ states at 550 keV. Level cross sections were obtained using these and previously measured angular distributions. The University of Lowell 5.5-MV pulsed Van de Graaff accelerator with a Mobley bunching system was employed to generate neutrons via the 7Li(p, n)7Be reaction. Metallic lithium targets were 8 to 10 keV thick, enabling an overall resolution of 15 to 20 keV to be maintained throughout the measurements. The scatterer was disk shaped. Details of data reduction and finite scatterer size effects are discussed. The experimental results are compared with theoretical results and ENDF/B-V.
