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.

Components that make up the central column of a tokamak have a strong impact on the overall sizing of the reactor. In most of the next generation tokamaks being considered at PPPL, the vessel is separate from the blanket support structures. A substantial structure is provided as nuclear and electromagnetic shielding to protect the inner legs of the TF and the vessel pressure boundary. The K-DEMO reactor uses a version of this concept.
This technical note addresses the structural adequacy of the K-DEMO vacuum vessel design as of November 2015. The vessel surrounds the internal vacuum components of the reactor and its primary purpose is only to provide the vacuum boundary for the rest of the internals. Static vacuum pressure stresses, stresses due to static magnetic loads, and approximate disruption stresses have been evaluated.
