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.

Recognizing that differential quantities are sometimes not of practical interest, a simple method for projecting integral quantities is presented. The technique uses only the measured moments of the differential quantity to predict other moments and does not require an explicit a priori knowledge of the differential spectrum. The particular application discussed involves prediction of integral quantities from multiple-foil neutron activations, including integral fast fluxes and activities. In energy regions with good response function coverage, the technique is shown to yield reasonably accurate predictions of the integral fluxes (within ∼15%) and other activities (within ∼30%) using a limited set of measured activities. The methods presented for predicting errors, however, were not as effective in providing reliable quantitative error estimates in all cases.
