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.

A perturbation method is described for the calculation of the heterogeneity effects on the multiplication factor and on the flux in fast reactors. It differs from the conventional perturbation method in that it uses an adjoint flux that is different from, but simply related to, the conventional adjoint. This new adjoint flux follows from the use of the collision-probability concept in the integral transport equation. The first-order changes in both the multiplication factor and the flux are simply expressed in terms of the conventional flux and adjoint flux obtained from homogeneous calculations. A procedure is described for the computation of higher-order changes. Qualitative results, as well as numerical results, are given. The application of the method to Doppler calculations in heterogeneous reactors is outlined.
