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.

Latest electricity cost estimates get new details on nuclear
Every year, the National Renewable Energy Laboratory (NREL) puts out a set of technology-specific cost and performance parameters for electricity generation. Now in its 10th year, the Electricity Annual Technology Baseline (ATB) has nearly 100,000 users from 144 countries, according to NREL. Utility planners and grid operators who look to the ATB to assess their investment options in a changing market require complete and accurate information and will be glad to know that the 2024 Electricity ATB, released June 24, includes—for the first time—a range of data on nuclear energy.

This paper presents a program to simulate performance of a liquid phase catalytic exchange (LPCE) column of a water detritiation facility based on combined electrolysis and catalytic exchange (CECE) technology over a wide range of deuterium contents in a feed stream. The program uses rate constants of the chemical isotopic exchange reactions between gaseous hydrogen and water vapor occurring on a hydrophobic catalyst and the mass transfer rate between water vapor and the film of liquid water on packing material in the LPCE column, which have been measured experimentally using a specially developed method and at a low concentration of deuterium in a three-isotope mixture. The effect of the deuterium presence on the kinetics of isotopic exchange reactions and the performance of the LPCE column are taken into account considering several possible mechanisms that can control the overall rate of reaction. Selection of the most suitable mechanism was carried out by comparing the simulations with the results of an experimental test with a large deuterium content.The simulation program allows calculation of isotope profiles in streams of liquid water, water vapor, and gaseous hydrogen along the LPCE column over a very wide range of isotopic compositions and for CECE facilities of several different layouts.
