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.

Three-dimensional (3D) correction factors designed to take into account the heterogeneity effects of the missing dimension in two-dimensional (2D) reactor computation are rigorously defined. An approximate method for computing the 3D correction factors is proposed by introducing simplified model cores. For verification of the proposed method, 2D and 3D ROCS code computations are performed for the first three cycles of the Yonggwang Unit 2 pressurized water reactor. The utility of the proposed method is then discussed by demonstrating that the 2D ROCS results with the use of the approximate 3D correction factors agree well with the 3D ROCS results in the letdown behavior of the critical soluble boron concentration and the core power distribution.
