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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Digital computers have been chosen in the implementation of safety critical systems in newly constructed nuclear facilities. These safety critical systems are designed to operate in a secure manner so that their failure should not prompt any serious damage or catastrophic effects. Due to the security significance of critical systems, there is a need to ensure the secrecy of systems at an early stage. Existing work focused on evaluating security by considering at the requirement phase only integrity, confidentiality, access control, and availability attributes. However, many essential critical attributes have not been taken into consideration, like deadlock, liveness, etc. To improve the security of software systems, this paper introduces a threat-driven modeling framework. It predicts security threats, it figures out which threats require mitigation and how to alleviate these threats, and it incorporates the essential missing attributes. We specify the functionality of the system with a Petri net, and we analyze the behavioral and structural properties of the system and threat mitigation. Aspect-oriented stochastic Petri nets are used as a formal amplified model. The technique has been validated on 11 safety critical systems of a nuclear power plant and it is shown for one case study in this paper.
