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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

This article is devoted to an extension of Galanin's heterogeneous theory to the tridimensional problems usually met in studies of small reactors. Clearly, this method is also applicable to bidimensional problems. Here also, it brings in several improvements compared with the parent theory, especially concerning the radial reflector, which can here be of finite dimensions. Significant numerical examples are given in the final section. The codes used—for the IBM 7090 computer—lead to times of calculation which are reasonable for small reactors. They may also be used for much bigger reactors provided that they are used to treat bidimensional problems only.
