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.

Triethylenediamine (TEDA) impregnated charcoals, used in nuclear reactors to safeguard against the release of airborne radioiodine, show high efficiency under various reactor operation and accident conditions when they are new. However, during normal operation, charcoal filters are continuously degraded (or weathered) due to the adsorption of moisture and other air contaminants. The effect of weathering on the efficiency of charcoal for removing radioiodine is of great interest. The results of a study on the adsorption behavior of various contaminants {NO2, SO2, 2-butanone [methyl-ethyl ketone (MEK)], and NH3} on TEDA charcoal are presented. This study is an attempt to characterize and quantify the weathering process of TEDA charcoal by these contaminants. The adsorption and desorption of characteristics of these contaminants range from completely irreversible (NO2) to completely reversible (NH3). The effect of adsorbed water (or humidity) on adsorption is different for each contaminant. Adsorbed water increases the adsorption rate and capacity of TEDA charcoal for NO2, while it does not significantly change those for SO2. However, it appears that SO2 is adsorbed as H2SO4 on the wet charcoal. Adsorbed water slightly reduces the adsorption capacity of the charcoal for MEK, but does not affect the adsorption of NH3.
