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 hydrodynamic characteristics of pulsed columns fitted with perforated sieve or baffle-plate internals are investigated experimentally using a Purex H2O-HNO3-U(VI)-30% tri-n-butylphosphate/dodecane liquid system. A set of semiempirical equations for axial mixing, mean diameter, and settling velocity of the droplets is derived from the experimental results and incorporated into the DYNAC computer simulation program to predict fluid flow behavior in pulsed columns. Various hydrodynamic parameters are studied in detail, and the code is demonstrated to be satisfactory in analyzing the residence behavior of fluids and the extractive mass transfer of uranium in normal and transient operations.
