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?

Extensive exploitation of nuclear raw materials requires the use of “nuclear breeding”, which is a phenomenon that can be attained in fast reactors. However, those reactors have had a complex history with some drawbacks and some important nuclear-policy attacks, as the INFCE initiative launched inside IAEA in 1978. Two points were very relevant in that context: the extensive use of plutonium recycling and an inherent property of fast reactors that could induce positive feedback between reactivity and thermal-hydraulics. In fact, a partial or total loss of coolant could convey a tremendous injection of reactivity, which could produce a catastrophe. An alternative to breeding in critical fast reactors is presented by hybrids, which are subcritical reactors which need an external neutron source for keeping their neutron population alive. Besides that, design and natural responses of the reactor systems against accidental initiating events have to be considered for arriving to the concept of Residual Safety beyond Design Limits. Such a final safety level will depend quite a lot on the type of coolant and the way the fuel is conformed into elements of a given geometry.
