Full textMaintenance strategies based on RCM method are difficult to assess, due to some methodological difficulties whose resolution is the scientific scope of this PhD Thesis: - the systems considered are composed of numerous dependent components with different degradation and failure phenomena, - maintenance strategies are complex, based on different tasks and without a simple structure. The objective of this PhD Thesis is to propose a method to quantify maintained systems performances. We propose a modelling framework which takes into account all the phenomena that describe multi-component system behaviour and complex maintenance strategy impact. A two-level structure allows a detailed description of components degradation/failure behaviour, all the possible maintenance tasks realisation and the consequences on the system. A global cost criteria based on system unavailability and maintenance costs renders possible to compare different strategies. The approach is implemented by using Petri nets and Monte Carlo simulation. The method is validated through its application on two systems from EDF nuclear power plants: - system AGR study presents the possible utilisations and the results obtained, - system TPA study illustrates the application on a real system and helps to define some further developments on data integration

Full textDegradation is an unavoidable phenomenon that affects engineering components and systems, and which may lead to their failures with potentially catastrophic consequences depending on the application. The motivation of this Thesis is trying to model, analyze and predict failures with prognostic methods that can enable a predictive management of asset maintenance. This would allow decision makers to improve maintenance planning, thus increasing system availability and safety by minimizing unexpected shutdowns. To this aim, research during the Thesis has been devoted to the tailoring and use of both model-based and data-driven approaches to treat the degradation processes that can lead to different failure modes in industrial components, making use of different information and data sources for performing predictions on the degradation evolution and estimating the Remaining Useful Life (RUL).The Ph.D. work has addressed two specific prognostic applications: model-based prognostics for fatigue crack growth prediction and data-driven prognostics for multi-step ahead predictions of time series data of Nuclear Power Plant (NPP) components.Model-based prognostics relies on the choice of the adopted Physics-of-Failure (PoF) models. However, each degradation model is appropriate only to certain degradation process under certain operating conditions, which are often not precisely known. To generalize this, ensembles of multiple degradation models have been embedded in the model-based prognostic method in order to take advantage of the different accuracies of the models specific to different degradations and conditions. The main contributions of the proposed ensemble of models-based prognostic approaches are the integration of filtering approaches, including recursive Bayesian filtering and Particle Filtering (PF), and novel weighted ensemble strategies considering the accuracies of the individual models in the ensemble at the previous time steps of prediction. The proposed methods have been validated by case studies of fatigue crack growth simulated with time-varying operating conditions.As for multi-step ahead prediction, it remains a difficult task of Prognostics and Health Management (PHM) because prediction uncertainty tends to increase with the time horizon of the prediction. Large prediction uncertainty has limited the development of multi-step ahead prognostics in applications. To address the problem, novel multi-step ahead prediction models based on Long Short- Term Memory (LSTM), a deep neural network developed for dealing with the long-term dependencies in the time series data have been developed in this Thesis. For realistic practical applications, the proposed methods also address the additional issues of anomaly detection, automatic hyperparameter optimization and prediction uncertainty quantification. Practical case studies have been considered, concerning time series data collected from Steam Generators (SGs) and Reactor Coolant Pumps (RCPs) of NPPs

Full textThis thesis deals with the conception of diagnosis systems using the data collected on identical machines working under different conditions. We are interested in the fault diagnosis method without a priori model and in modelling a fleet of machines using the data collected on all the machines. Hence, the problem can be formulated as a multi-task learning problem where models of the different machines are constructed simultaneously. These models are supposed to share some common parts. In the second chapter, we first consider linear models of type multiple-input/single-output. A first approach consists in analyzing the linear regression models generated using the data of each machine independently from the others in order to identify their common parts. Using this knowledge, new models for the machines are generated. The second approach consists in identifying simultaneously the coefficients of the models and their common parts. Secondly, the redundancy models are searched for using PCA. This way, no hypothesis on the knowledge of the structures of models describing the normal behavior of each machine is needed. In addition, this method allows to take into consideration the errors existing on all the variables since it does not differentiate between input or output variables. In the third chapter, a study on the discernibility of the outputs of the models is realized. The problem consists in identifying the range of variation of the input variables leading to discernible outputs of the models. This problem is solved using either the confined pavements to the different domains or a pavement method. Finally, the multi-task modelling approaches are applied on simulators of heat exchangers

Full textGiven the stringent requirements of high levels of safety in nuclear components, stakeholders of the French nuclear industry must anticipate the presence of residual surface imperfections in these components. Such imperfections could be introduced during manufacturing or maintenance operations. The incidence of surface irregularities on the fatigue strength of metallic components has tobe considered. Meanwhile, nuclear components can be loaded under low-cycle fatigue and large-scale plasticity conditions. The first objective of this work isthento assess to what extent the fatigue life of typical nuclear materials may be affected by the presence of such surface irregularities. In parallel, thisstudy aims at describing, qualitativelyand quantitatively, the crack initiation and propagation from these imperfections. In order to meet these objectives, a uni-axial fatigue test campaign, conducted under fully-reversed total axial strain control, in the air at room temperature, has been carried out on the cylindrical specimens (Φ 9 mm). Surface imperfections were artificially introduced onto the specimens. The electric potential trackingmethod has been mainly usedto monitor the crack initiation, micro and macro propagation phases from surface imperfections. Additional experimental and numerical actions have been carried out to calibrate the potential monitoring. The results of thetest campaigndemonstrate a significant influence of the presence of imperfections on the9 mm specimensfatigue strength. The useof electrical methodhas allowedto determine crackinitiation and growth ratesfrom surface imperfections. The identification of a representative parameter of the propagation driving force,in the context of generalized plasticity associated with the tests carried out,has also allowed to analysedata relating to propagation kinetics in a predictive perspective

Full textThe design of an advanced SFR demonstrator, the ASTRID reactor (Advanced Sodium Technological Reactor for Industrial Demonstration) at CEA implies the development and validation of scientific calculation tools, in order to create a safety dossier. Notably, the use of neutronic codes aims at defining the characteristics of reactor cores with well-mastered accuracies. Nuclear data, the input parameters of these codes, constitute the main source of uncertainty in neutronic calculations. The purpose of this PhD is to reduce uncertainties associated to nuclear data, and hence better predict the characteristics of the ASTRID core, using Integral Data Assimilation. This method, based on Bayesian-Laplace Inference, consists in using integral data C/E (calculation-to-experiment ratio) to perform adjustments on the central value and uncertainties of nuclear data. The modifications on nuclear data suggested by assimilation results have been used to quantify the bias and the reduced uncertainties associated to the ASTRID core main characteristics
