DOE announces awards for three university nuclear education outreach programs
The Department of Energy’s Office of Nuclear Energy has announced more than $590,000 in funding awards to help three universities enhance their outreach in nuclear energy education. The awards, which are part of the DOE Nuclear Energy University Program (NEUP) University Reactor Sharing and Outreach Program, are primarily designed to provide students in K-12, vocational schools, and colleges with access to university research reactors in order to increase awareness of nuclear science, engineering, and technology and to foster early interest in nuclear energy-related careers.

A new daily as-run thermal analysis was performed at the Idaho National Laboratory for the advanced gas cooled reactor (AGR) test experiment number two (AGR-2) in the Advanced Test Reactor (ATR). This thermal analysis incorporates gas gaps changing with time during the irradiation experiment due to graphite shrinkage resulting from neutron damage. The purpose of this analysis was to calculate the daily average temperatures of each TRISO (tristructural isotropic)–particle fuel compact. A steady-state thermal analysis was performed daily for each capsule with the commercial finite element heat transfer code ABAQUS. These new thermal predictions show the compact fuel temperature dependence on the variable gas gap method. Comparison between measured and calculated temperatures is discussed.
