IEAR1 Renewed Primary System Pump B1B Nozzles Stress Analysis

Abstract

The present report is a summary of the structural analysis of the pump nozzles applying the finite element method by using the ANSYS computer program. The IEA-R1 Research Reactor is an open pool-type moderated and cooled by light water using beryllium/graphite as a reflector. The Reactor can reach up to 5MW heating power and coolant by two systems composed of the primary and secondary systems. The primary coolant system consists of a piping system, a decay tank, two pumps, and two heat exchangers. The pump B1-B presents some failure requiring being refurbishment by a new one. Every pump equipment manufacturer has its own requirements for its specific pump models. The requirements to use a pump in the research reactor must follow some requirements and specific codes, design, and operational requirements of the IEAR1 Reactor, as consequence a structural analysis was performed.
