Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

In solvent extraction for nuclear fuel reprocessing, a stable emulsion called “crud” is formed at the interface between the organic and aqueous phases. Crud is an emulsion stabilized by finely dispersed solids. Process disturbances are often induced by crud. Accordingly, crud should be eliminated from the interface in the extractors. The eliminated crud is stable and highly radioactive; thus, the treatment of this crud may be difficult. Complexes of zirconium and tributyl phosphate (TBP) degradation products, such as phosphoric acid (H3PO4) and mono-n-butyl phosphate (H2MBP), are one source of the fine particles that stabilize emulsions in the extraction process. A chemical treatment method to demulsify crud stabilized by precipitates of Zr-H3PO4 and Zr-H2MBP is studied. Experimental results indicate that neutralization by an alkaline solution, particularly sodium carbonate, is very effective for the destruction of this crud.
