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.

Neutron transport calculations need an accurate treatment of cross sections. Two methods (multigroup and pointwise) are usually used. A third one, the probability table (PT) method, has been developed to produce a set of cross-section libraries, well adapted to describe the neutron interaction in the unresolved resonance energy range. Its advantage is to present properly the neutron cross-section fluctuation within a given energy group, allowing correct calculation of the self-shielding effect. Also, this PT cross-section representation is suitable for simulation of neutron propagation by the Monte Carlo method. The implementation of PTs in the TRIPOLI-3 three-dimensional general Monte Carlo transport code, developed at Commissariat à l'Energie Atomique, and several validation calculations are presented. The PT method is proved to be valid not only in the unresolved resonance range but also in all the other energy ranges.
