Thomas Newton, Daniel J. Flynn, Robert Williams
The National Bureau of Standards Reactor at the NIST Center for Neutron Research (NCNR) is a 20 MW reactor using 93% enriched UO 2 plate-type fuel with D 2O coolant, moderator, and reflector, and is used for a variety of neutron science applications. 23 of

Neutronics and Safety Studies on a Research Reactor Concept for Advanced Neutron Sources

July 17, 2017
Author(s)
Zeyun NMN Wu, Robert E. Williams, J. Michael Rowe, Thomas Henderson Newton, Sean O'Kelly
This paper presents the neutronics and thermal-hydraulics safety analysis results for an LEU-fueled research reactor concept being designed and studied at NIST. The main goal of the research reactor is to provide advanced neutron sources for scientific
