dc.description.abstract-translatedThis study investigates pyrex insertion eSects on reactor physics parameters in Westinghouse SMR configurations using OpenMC Monte Carlo simulations. Three core configurations were analyzed: reference core, partial pyrex insertion, and full pyrex insertion. Results demonstrate significant reactivity reduction with progressive pyrex implementation. Flux distributions show enhanced flattening and improved power homogenization with pyrex presence. Temperature coeSicients became increasingly negative, strengthening inherent safety margins, while control rod eSectiveness increased substantially. Spatial neutron flux and fission rate distributions reveal localized absorption eSects in pyrex regions with corresponding redistribution of neutron population. OpenMC simulations accurately captured complex neutron-absorber interactions in heterogeneous SMR core geometries. The findings validate pyrex eSectiveness as a viable solution for reactivity control and flux optimization in small modular reactor applications requiring precise neutron management and enhanced safety characteristics.en
