Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The CERES collaborative program between the French Atomic Energy Commission (CEA) and the United Kingdom Atomic Energy Agency (UKAEA) was performed in the MINERVE and DIMPLE reactors at Cadarache and Winfrith, respectively. CERES Phase II was devoted to the validation of fission product (FP) poisoning through the reactivity worth measurements of FP samples. This paper describes the oscillation experiment at the center of the MINERVE pressurized water reactor–type test lattice. This experiment is strongly representative of the FP poisoning in light water reactor spent fuels because the separated FP isotope is introduced into real UO2 pellets where 238U/iFP resonance overlap occurs. In order to preserve the experimental results within the International Reactor Physics Experiment Evaluation international database, slight corrections to define a two-dimensional benchmark are presented. The evaluation of experimental uncertainties is detailed. Therefore, the accurate APOLLO2.8 analysis of this benchmark is described, using recent JEFF-3.1.1 and ENDF/B-VII.0 nuclear data files. JEFF-3.1.1 FP worth is particularly satisfactory, except for 153Eu, which is underestimated by 8.1% + 2.6%. The CERES integral measurement data also suggest improvements to 99Tc and 145Nd evaluations in the ENDF/B-VII.0 library.
