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.

The method of singular eigenfunction expansions is applied to the time-independent one-speed Milne problem in which there are two half-space media. It is assumed that scattering in each medium is at most linear in the cosine of the scattering angle; closed form expressions are then obtained for the expansion coefficients. Numerical results show the dependence upon the scattering parameters of the extrapolation distance and the discontinuities in the asymptotic densities and currents at the interface. These results give the proper boundary conditions to be applied when using diffusion theory in problems involving two or more plane layers which are thick as compared to the mean-free-paths of the media.
