Fusion Energy Week begins today
Fusion is riding a surge of attention that began in December 2022 when researchers at Lawrence Livermore National Laboratory’s National Ignition Facility achieved fusion ignition. The organizers of Fusion Energy Week—a group called the U.S. Fusion Outreach Team—on the other hand, trace fusion development back 100 years to the doctoral research of Cecilia Payne-Gaposchkin, who discovered that stars, including our Sun, are mostly made of hydrogen and helium, which in turn led to the understanding that those elements are the “fuel” of potential fusion energy systems on Earth. In recognition of Payne-Gaposchkin’s birthday—May 10—the U.S. Fusion Outreach Team plans to hold a “grassroots celebration of fusion energy” May 6–10, 2024, and annually during the second week of May.

The radiation effects in the fiber, matrix, and interface components of the SiC/SiC composite material are important input for lifetime assessment. Neutronics calculations were performed to determine the radiation damage parameters in the fiber/matrix and the candidate interface materials. The radiation damage parameters were calculated for both the carbon and silicon sublattices. The radiation damage parameters were evaluated for representative candidate breeding blankets. The breeder and/or coolant such as Pb83Li17, Flibe and Li2O affect the radiation damage parameters by impacting the neutron spectrum. The results provide an essential input for SiC/SiC composite lifetime assessment. The impact of the unique features of inertial fusion systems on damage parameters are identified.
