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 shattered pellet injector (SPI) based on in situ technology was developed in the HL-2A tokamak. In this paper, the basic principle of pellet formation is introduced, the mechanism of a SPI is described in detail, and test results are presented. Bench test experimental results show that reliable formation and acceleration of a large nitrogen pellet (diameter of ∼3.5 × 4 mm) were obtained. A double-impact tube was developed and tested for effective and reliable shattering of the pellet.
