Abstract

With the rise in interest of GEN-IV reactor systems, newer and more accurate thermal neutron scattering nuclear data are needed. Both GEN-IV reactors and current light water reactors applying for license extensions require high fidelity cross sections and uncertainties to better thermal margins and thereby maximizing energy production and improving economics and safety. This talk will outline some of the recent efforts in evaluating new thermal neutron scattering materials of interest for both current reactor systems and advanced reactor technologies, as well as discuss methods for evaluating uncertainties in thermal neutron scattering data and how they propagate to observables in nuclear criticality safety applications.

Biography

Dr. Chris Chapman received his Bachelors of Science in Nuclear Engineering and Physics from Texas A&M University in 2012. He then received both his Masters and Ph.D. degrees in Nuclear Engineering from Georgia Tech in 2015 and 2017 respectively. Since then, he has worked at Oak Ridge National Laboratory first as a post-doc, then as an R&D staff associate. During that time, he worked on multiple aspects of nuclear data evaluation and analysis, ranging from thermal neutron scattering evaluations, resolved resonance region evaluations, and improving the nuclear data processing code AMPX.
