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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

We introduce a concept of laser-generated neutrons to transmute transuranic elements separated from spent nuclear fuel (SNF) and dissolved in a molten salt to form a subcritical core whose liquid state allows and facilitates safety, laser irradiation, and monitoring of chemical and physical properties. In this transmutation concept (the transmutator), the neutrons are generated via beam-target fusion whereas the beam is created by laser irradiation of nanometric foils through the Coherent Acceleration of Ions by Laser (CAIL) process. This relatively low deuteron energy is catapulted by fusion and eventually by secondary fission processes. The combination of the use of molten salt and laser allows us to introduce rapid feedback control of the system’s operation. The transmutator is an integral part of the partitioning and transmutation concept whereby the radiotoxicity of SNF is significantly reduced together with the required storage duration and volume. To enable this transmutator, we introduce integrated ideas and processes in the areas of lasers, neutronics, first-wall material, and chemistry.
