ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Dilute aqueous solutions of two surface active agents (surfactants) were tested for their ability to suppress spontaneous steam explosions in molten tin/water systems. At 800° C, 12 g of tin were dropped into aqueous solutions of a nonionic surfactant (nonylphenol polyethylene glycol ether) and an ionic surfactant (dodecylbenzene sulfonate sodium salt) with concentrations of 5, 10, and 50 wppm. The data indicate that surfactants reduce the severity of steam explosions. On average, the surfactant solutions resulted in a 65% reduction in average peak pressures when compared with the deionized water results. However, very little difference in the mitigating effect of the surfactant solutions was observed as the concentration was increased beyond 5 wppm. Particle-size distribution results also indicated a mitigating effect on steam explosion severity, as a 19% reduction in participating melt mass fraction was observed when the surfactants were used.
