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.

Finding fusion’s place
Fusion energy is attracting significant interest from governments and private capital markets. The deployment of fusion energy on a timeline that will affect climate change and offer another tool for energy security will require support from stakeholders, regulators, and policymakers around the world. Without broad support, fusion may fail to reach its potential as a “game-changing” technology to make a meaningful difference in addressing the twin challenges of climate change and geopolitical energy security.
The process of developing the necessary policy and regulatory support is already underway around the world. Leaders in the United States, the United Kingdom, the European Union, China, and elsewhere are engaging with the key issues and will lead the way in setting the foundation for a global fusion industry.

This study evaluates convective and boiling heat transfer characteristics of a water impinging jet flow in porous media in order to remove the heat flux of 10 MW/m2 imposed to fusion divertors. The metal porous media with complicated microchannels have large heat transfer surface due to fin effect and superior mixing effect of fluid, which enhances not only the convective heat transfer but also the boiling heat transfer by improving the evaporation rate of the cooling liquid. In a proposed heat removal device called EVAPORON-3-Type3, the cooling water is supplied as an impinging jet flow into the porous medium, which is a two-layered copper particle bed, and the generated vapor is discharged through high porosity gaps on the heat transfer surface. As a result, the convective heat transfer coefficient is improved by 1.6 times compared with that of an impinging jet flow without the copper particle bed. In the boiling heat transfer regime, the critical heat flux is increased by 1.5 times and the heat flux of 8.4 MW/m2 is achieved under low velocity and highly subcooled conditions though it’s not maximum.
