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.

The method of multinodal treatment of nuclear transition and spatial migration of radioactive materials in complex nuclear technological systems is described. The modeling of such processes is established in a very flexible way, enabling the user to investigate a wide range of problems related to nuclear safety, i.e., to predict the radioactive source term in normal operation and under accidental conditions of any nuclear plant. The migration of radioactive material can be connected either with the flow of reactor coolant or with any of the other physicochemical processes (filtration, deposition, etc.). On the basis of this method, a modular code system - TIBSO - has been developed.
