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.

Temperature parallel simulated annealing (TPSA) was applied to in-core fuel management optimizations, and the optimization performance was evaluated by comparing TPSA with traditional simulated annealing (SA). The TPSA method is an optimization algorithm that is based on SA, but has several distinguishing features: an automatic temperature annealing schedule, time homogeneity, and a significant affinity with parallel execution. The calculation results of a test problem revealed that TPSA was superior to traditional SA in terms of detailed loading pattern optimizations. The reason for this is that the TPSA temperature annealing schedule can effectively avoid local optima by repeating a cooling and heating cycle automatically.
