DOE awards $134M for fusion research and development
The Department of Energy announced on Wednesday that it has awarded $134 million in funding for two programs designed to secure U.S. leadership in emerging fusion technologies and innovation. The funding was awarded through the DOE’s Fusion Energy Sciences (FES) program in the Office of Science and will support the next round of Fusion Innovation Research Engine (FIRE) collaboratives and the Innovation Network for Fusion Energy (INFUSE) awards.

A high-power neutron-producing spallation source is one option for meeting the mission of a fusion prototypic neutron source (FPNS). The Los Alamos Neutron Science Center at Los Alamos National Laboratory is uniquely suited to host such a source. A target concept has been developed that satisfies the initial goals established for an FPNS, as has a beam transport design that satisfies beam-on-target requirements for the concept. We discuss the potential impact of pulsed beam operation on radiation-induced changes in microstructure, as well as the ingrowth of calcium in steel alloys at a rate well beyond that expected in a fusion reactor first wall. A preliminary thermomechanical assessment shows the need to modify the target design to reduce temperatures and stresses in the tungsten target.
