Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

This paper reports the results of the second phase evaluation of the EVOLVE W-alloy first wall and blanket design cooled by vaporizing lithium. For the transpiration-cooled first wall and blanket concept, we identify the need to further quantify the data of lithium superheat from W-alloy heated surface and bulk lithium slabs. For the boiling lithium blanket, we identify the need to elucidate the impacts of magnetic field on various stable-boiling regimes. We also find that this FW/blanket concept should have no problem in achieving adequate nuclear performance. With the addition of passive cooling loops, the concept has a strong possibility of achieving the safety requirement of not needing a public evacuation plan under the loss of power accident conditions. Even though the irradiated W-alloy may be subject to embrittlement, due to the relatively low system pressure of the design, it is shown to be able to withstand a large number of cracks. The fundamental issues of W-alloy properties under high neutron fluence irradiation and the components fabrication technique remain. Preliminary investigations of W-alloy fabrication and heat flux removal through SBIR programs have begun and the initial results arc encouraging. We recommend that the investigation of critical issues of the EVOLVE concept continue since this innovative design has a good possibility of showing a way to achieve high performance and passively safe designs that are necessary for the utilization of fusion power.
