ROP Optimization Modules in ROVER-F

Abstract

To maximize reactor operating margin, interest has focused on optimizing the regional overpower protection (ROP) in-core detector systems. Two potential means of accomplishing this task are using fuel-management techniques to increase ROP margins (REFORM), and detector-layout optimization (DLO), which selects assembly and detector locations where they are of maximum benefit. ROVER-F is the design and analysis ROP code that AECL uses to perform probabilistic assessments of the ROP systems. It has recently been expanded to address REFORM and DLO tasks.
