Maintainability Policy for Deteriorating System with Inspection and Common Cause Failure (TECHNICAL NOTE)

A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...

Explicit and implicit methods for probabilistic common-cause failure analysis

The occurrence of a probabilistic common-cause failure (PCCF) in a system results in failures of multiple system components with different probabilities. A PCCF can be caused by external shocks or propagated failures originating from some components within the system. This paper proposes an explicit method and an implicit method to analyze the reliability of systems subject to internal or exter...

Fuzzy Reliability Evaluation of a Repairable System with Imperfect Coverage, Reboot and Common-cause Shock Failure

In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

Heat Structure Coupling of CUPID and MARS for the Passive Auxiliary Feedwater System Analysis

In the present study, the CUPID code was coupled with a system analysis code MARS and the coupled code was applied for the simulation of the PASCAL test facility [1], which is constructed to validate the cooling performance of the Passive Auxiliary Feedwater System (PAFS). The two-phase phenomena in the steam supply system including the condensation in the Passive Condensate Heat Exchanger (PCH...

Physics-based Common Cause Failure Modeling in Probabilistic Risk Analysis: a Mechanistic Perspective

The modeling of dependent failures, specifically Common Cause Failures (CCFs), is one of the most important topics in Probabilistic Risk Analysis (PRA). Currently, CCFs are treated using parametric modeling, which is based on historical failure events. Instead of utilizing the existing data-driven approach, this paper proposes the concept of physics-based CCF modeling, which refers to the incor...
