REDESIGNING INTERLOCK SYSTEMS FOR THE UPGRADE OF MINIATURE NEUTRON SOURCE REACTORS (MNSRS): A CONCEPTUAL APPROACH

Interlock systems are vital safety components integral to the secure functioning of safety-critical industrial plants. They play a crucial role in preventing or minimizing potential hazards by automatically triggering shutdowns or other protective measures when specific predefined conditions are detected. These systems are an essential part of the safety architecture, contributing to the overall risk mitigation in industrial settings. This paper underscores the successfulconceptual redesign and validation through simulation of the proposed interlock system for the upgrade of miniature neutron source reactor (MNSR) safety. Emphasizing its robust functionality, precise timing control, and strategic incorporation of on-delay functions. The comprehensive assessment of different operational conditions highlights the system's responsiveness and crucial role in ensuring safety, stability, and efficiency across a diverse range of scenarios. This is to introducea higher safety margin for MNSR operation.
