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.

A process for separating transcurium elements from americium and curium was developed and tested in laboratory scale experiments. This separation is based on preferential extraction of the transcurium elements into 2-ethylhexylphenylphosphonic acid [2-EH(P)A] from dilute hydrochloric acid solutions. Single-stage separation factors between californium and curium are as great as 100. Extraction positions of the transplutonium elements are americium < curium ≪ berkelium < californium < einsteinium < fermium. Distribution coefficients are directly proportional to the cube of the extractant concentration in the solvent and inversely proportional to the cube of the acid concentration in the aqueous phase over the range from 1 to 4 N.
