Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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 FIRE experiment1 will present a net electric power demand approaching 1000MW for 10's of seconds, repeated once every 2 hours, delivered to the load via thyristor AC/DC converters which exhibit a widely varying power factor. The issues associated with the supply of such a load from the utility grid can be divided into two categories:
▪transmission line power flow vs. capacity▪voltage deviation within the grid vs. limits▪frequency deviation within the grid vs. limits▪loading of electrical equipment (e.g. generators)▪control of power generation (e.g. steam turbines)
