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.

The generation of tritium from the 10B(n, 2α)3H reaction involving boric acid in the coolant-moderator of PWRs is studied. First, the total amount of tritium produced by this process during a core cycle is calculated for the case of base load operation assuming separability of the neutron flux into space, energy, and time modes as well as a linear decrease of the boric acid concentration in compensation for burnup effects. Subsequently, analytic solutions to this problem are obtained for square-wave load-following assuming both total and one particular mode of partial compensation of the reactivity transients due to xenon poisoning by boric acid. The limitation to load following due to practical limitation of the dilution rate is observed. The solutions are expressed in terms of commonly available plant parameters and are presented in graphical form as a function of characteristics of the load following program. The significance of the analysis is illustrated by means of a numerical example; details of the xenon-transient analysis are included as an appendix.
