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.

Article considers incorporation of AI into nuclear power plant operations
The potential application of artificial intelligence to the operation of nuclear power plants is explored in an article published in late December in the Washington Examiner. The article, written by energy and environment reporter Callie Patteson, presents the views of a number of experts, including Yavuz Arik, a strategic energy consultant.

The use of induced time-dependent 222Rn behavior to determine source rate magnitudes, ventilation rates (air change rates), and other parameters that affect 222Rn and progeny levels and exposure to building occupants is investigated. When the subject space is purged and the buildup (seepage) back into the space is measured, theoretical, normalized equations show a unique, one-to-one correspondence of the 222Rn and particulate progeny temporal levels to the air change rate in the space. The Bateman equations have been solved in closed form for 222Rn and progeny in air and trapped on a filter under these conditions. A total of 28 measurements of the time-dependent behavior of radon progeny for two test facilities [one with a constant air change rate and one with a constant National Institute of Standards and Technology (NIST)-calibrated source] and four residential dwellings were made. The results were compared with theory and with air change rate measurements made by anemometer flow rates and by the conventional method (SF6 decay). For a factor of 2 range in air change rates in the NIST constant source case, the agreement with the SF6 method air change rate was within ±10.6% standard deviation and agreement with the NIST source magnitude of 37.0 ± 1 kBq was within ±4.9% standard deviation. Agreement to within ±17.7% standard deviation was obtained on determination of air change rates for the residential dwellings. Based on the airborne concentrations and air change rates, source emanation rate magnitudes were obtained. Analyses of the results are presented in detail, and factors affecting the accuracy and feasibility of the method are identified.
