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.

In solving photon transport problems by the Monte Carlo method, parallel-type computers are not well suited to the use of the customary rejection technique for selecting photon wavelength upon scattering. Two techniques of determined length and therefore greater suitability have been studied, with particular application to a machine having 64 processing elements, such as ILLIAC IV. The method involving solutions by Newton’s method of the exact equation derived from the Klein-Nishina formula is found to be still more time-consuming than the rejection technique on both sequential and parallel computers. However, newly devised approximation formulas, corrected by weight adjustment factors, have been found to be much quicker on a parallel computer than the rejection technique, and even competitive on a sequential computer.
