DOE opens pilot program to authorize test reactors outside national labs
Details of the plan to test new reactor concepts under the Department of Energy’s authority but outside national laboratory boundaries—first outlined in one of the four executive orders on nuclear energy released on May 23—were just released in a request for applications issued by the DOE.

Areal mass densities of carbon dust collected in the baffle and divertor regions of JT-60U were investigated. On the plasma-facing surface, large areal density of 610 mg/m2 is found at the upper tile of the inner divertor, which is much larger than other areas due to the soft deposition. On the other hand, as for the plasma-shadowed area, largest areal density of 5,100 mg/m2 was found underneath the dome structure. The total dust weights at the plasma-facing surface and the shadowed areas were estimated to be 1.3 g and 22.2 g, respectively, assuming the toroidal symmetry. Count-based size distributions were also investigated. The average dust size of the main population is less than 20 m for both the plasma-facing surface and the shadowed area.
