Systems Engineering approach to Reliability Centered Maintenance of Containment Spray Pump

Abstract

: This paper introduces a systems engineering approach to reliability centered maintenance to address some of the weaknesses. Reliability centered maintenance is a systematic, disciplined process that produces an efficient equipment management strategy to reduce the probability of failure [1]. The study identifies the need for RCM, requirements analysis, design for RCM implementation. Value modeling is used to evaluate the value measures of RCM. The system boundary for the study has been selected as containment spray pump and its motor drive. Failure Mode and Criticality Effects analysis is applied to evaluate the failure modes while the logic tree diagram used to determine the optimum maintenance strategy. It is concluded that condition based maintenance tasks should be enhanced to reduce component degradation and thus improve reliability and availability of the component. It is recommended to apply time directed tasks to age related failures and failure finding tasks to hidden failures.

Concept definition of Small-Medium Reactor Coolant System using System Engineering

“…If there is any over stated operational requirement, then it is fed back or retreat to the operational analysis for re-evaluation since strategies may not be able to meet the operation requirements [4].…”
