Abstract A probabilistic structural integrity assessment framework utilizing a two-loop Monte Carlo simulation process is proposed. The process and interpretation of the results are demonstrated using an example of Steam Generator (SG) tubing with fretting flaws. Acceptance standards established using a 95/90/90 criterion (which represents 95% probability at 90th percentile with 90% one-sided confidence) is proposed and compared with the generally accepted deterministic and traditional probabilistic acceptance standards.

The sources and characters of uncertainties in engineering modeling for risk and reliability analyses are discussed. While many sources of uncertainty may exist, they are generally categorized as either aleatory or epistemic. Uncertainties are characterized as epistemic, if the modeler sees a possibility to reduce them by gathering more data or by refining models. Uncertainties are categorized as aleatory if the modeler does not foresee the possibility of reducing them. From a pragmatic standpoi...

Abstract This paper presents a Monte Carlo uncertainty/variability analysis applied to assessment of salmonid embryo survival affected by the deposition of fine sand in the spawning gravel riverbed. For the system being modeled, the uncertainty originates from the lack of perfect knowledge about the spawning habitat, while the variability arises from the natural diversity in the amount of sand deposit. A second-order Monte Carlo simulation (MCS) procedure consisting of multiple realizations of m...

Abstract Probabilistic fracture mechanics (PFM) simulates the behavior of cracked structures and propagates uncertainties from input parameters to a failure probability or its uncertain estimate. In nuclear technology, this approach supports the assessment of the rupture probability of highly reliable pipes, which is an important parameter for the safety analysis of a nuclear power plant. For the appropriate probabilistic modelling of a structure with consideration of uncertainties, but also for...
Abstract In this study, a systematic three-dimensional finite element analyses (3D FEA) are performed to evaluate the Mode II stress intensity factor (SIF) for circumferential through-wall cracked pipe under torsion moment. A wide range of crack lengths and pipe radius over thickness ratios are considered. Empirical solution of the mid-thickness Mode II SIF is developed as functions of crack lengths and pipe sizes. The deviating angle and the effective SIF regarding a through-wall crack (TWC) un...

Ultrasonic testing is a useful approach for quantifying the flaws in mechanical components. The height of the flaws in ultrasonic angle beam testing is closely related to the calibration value of the probe refraction angle. In order to reduce the calibration error, some ignored data during the traditional calibration process are reanalyzed and fused to determine the refraction angle. Both arithmetical measurement fusion method and weighted measurement fusion method are applied and compared. Mont...

Abstract This paper presents the first output of the International Atomic Energy Agency (IAEA) Coordinated Research Project (CRP), titled Methodology for Assessing Pipe Failure Rates in Advanced Water-Cooled Reactors (AWCRs), launched in 2018. This IAEA CRP is aimed at developing a good-practices document for estimating the probabilistic failure metrics of piping in AWCRs. The reliability of piping that comprise the Reactor Coolant Pressure Boundary (RCPB) is important for maintaining safe and s...

Abstract Steam generator is one of the major components in a nuclear power plant, and it consists of thousands of thin-walled tubes. The operating record of the steam generators has indicated that a number of axial cracks due to stress corrosion have been frequently detected in the tubes. Since the tubes are closely related to the safety and also the efficiency of a nuclear power plant, an establishment of the appropriate repair criterion for the defected tubes and its applications are necessary...

Abstract The objective of this paper is to demonstrate how the process of uncertainty designation (aleatory vs. epistemic) and subsequent separation in a two-staged nested Monte Carlo simulation approach may lead to misinterpretation of the study results, particularly with respect to the confidence (i.e., lower and upper bounds) in the estimated probabilities. Using simple examples, a critical distinction is made between first- and second-order random variable problems, which has a direct bearin...
