Annual Conference opening plenary: Full speed ahead
The 2024 American Nuclear Society Annual Conference opened with a bang yesterday as 1,200 attendees gathered in Las Vegas to network, collaborate, and socialize. Honors and awards were presented to several recipients, and ANS welcomed twelve new Fellows.
The plenary opened with an address from ANS Executive Director/Chief Executive Officer Craig Piercy that brought this year’s theme to the fore straight away: The time is now to deploy new nuclear projects—and not acting at this moment is simply not an option.

In this study, deposition of I2(g) on stainless steel tubing was investigated. The purpose was to quantify the rate of iodine deposition and desorption, as well as to elucidate the underlying mechanisms. The parameters included I2 gas phase concentration (10-7 to 10-11 M), relative humidity (<25 to 100%), tube surface temperature (23 to 90°C), and steel type (SS-304L and SS-316L). Gaseous I2 was found to deposit through both physical and chemical adsorption with deposition velocities ranging from 5 × 10-3 to 1.0 cm/s. At concentrations below 10-9 M, I2 rapidly deposited and was easily desorbed, consistent with physical adsorption. At concentrations above 10-9 M and low relative humidity (<25%), both adsorption and desorption were slow, consistent with a slow chemisorption process. At high relative humidity (>75%), rapid chemisorption with pitting corrosion occurred. Under some conditions, adsorption became inhibited resulting in an apparent maximum surface loading. At high iodine concentration, high relative humidity, and tube temperatures of 40 or 60°C, no such inhibition occurred, resulting in rapid and continuous iodine adsorption.
