Abstract

Integrating a (Zr3Si2) Composite Neutron Reflector and Concrete-Lead Alloy Bio shield in a Boiling Water SMR. This research demonstrates the potential of a dual-layered system to enhance safety in nuclear reactors, showcasing synergistic performance in neutron reflection and radiation absorption. The thick concrete-lead bio shield effectively contains neutrons formed during fission, maintaining optimal neutron economy. The study evaluates various composites for neutron reflection and supports the use of Zirconium-Silicon alloy due to its proven efficacy. The selected (Zr3Si2) composite-based neutron reflector ensures the containment and reflection of electrons during the fission process. The research delves into microstructure and phase diagrams of the alloys, emphasizing a meticulous rolling procedure in manufacturing for a uniformly integrated structure. Real-world applicability is highlighted within BWRX-300 SMR reactors. This work represents a significant step in fortifying safety standards and explores innovative solutions for neutron reflection in nuclear reactors.
