PROJECT TITLE Support for XFEM component integrity analysis 2.

BACKGROUND Operating experience has shown that dissimilar metal welds using Alloys 82 and182 exposed to primary coolant water (or steam) under the normal operating conditions of pressurized water reactors (PWRs) are susceptible to primary water stress corrosion cracking (PWSCC). This cracking typically initiates at the inside surface of these component welds when exposed to reactor coolant and in the presence of high tensile residual stresses introduced by welding (or weld residual stresses), and can progress through the thickness of the component leading to leakage and even rupture. In response to this potential degradation of the reactor pressure vessel boundary the NRC requires augmented inspections of susceptible components in order to identify PWSCC flaws before they compromise component integrity and allow for repair and replacement. When flaws are identified, licensees must then complete a flaw analysis to verify that the flaw will not grow to failure before the next inspection; otherwise, they must repair or replace the component. If the licensee analysis determines that it is safe to continue operating with the flaw in place, the analysis is then reported to the NRC for approval. When regulatory staff review these flaw analyses, independent confirmatory analyses are often required.

Traditionally this flaw analysis is done by first determining the weld residual stresses (WRS), and then analyzing how the crack would grow through that stress field.

Current practice involves determining the WRS profile of the component using finite element models, and applying it to standard ASME Code empirically based PWSCC growth models to determine the crack growth rate. Currently, NRC is capable of performing this type of analysis accurately and efficiently in order to assist regulatory staff in a timely manner. However, while useful for estimating crack growth in simple components and geometries that can be approximated using two-dimensional models, this generic approach requires excess conservatism in order to ensure broad applicability, and these simple representations begin to lose their meaning when applied to more complicated three-dimensional components with more complex stress states.

As computational power increases and finite element modeling techniques improve, licensees seek to improve their analyses to eliminate unnecessary conservativisms and analyze more complex components where the standard empirical models are not applicable. In order to do so, traditional flaw growth analyses are being replaced by finite element models to predict crack growth rate.

Historically, simulating cracks and crack growth using conventional finite element analysis (FEA) has proven difficult and time consuming especially for modeling realistic multi-directional crack growth. More recently, methods that allow for realistic crack growth to be modeled using straight forward techniques have been developed.

Specifically, the extended finite element method (xFEM) is a FEA tool that allows for

Page 4 mesh-independent analysis of discontinuities and singularities, and can be used to simulate crack growth in complex geometries in a simplified manner [1]. This capability is currently available to NRC through the use of ABAQUS. ABAQUS implementation of xFEM is potentially a powerful tool for representing cracks and simulating crack growth in industry relevant models. With the right choice of elements and meshing parameters, xFEM has proven capable of simulating critical and fatigue crack growth rates in complex systems, with results that closely match classic numerical and experimental results [2]. In some cases, xFEM results have shown to be extremely reliable, and have been used in developing industry standards regarding flaw proximity analysis [3], [4], [5]. Authors have also investigated the ABAQUS implementation of xFEM to calculate stress intensity factors for pre-existing cracks, and found good agreement with stress intensity factors generated with traditional FEA meshes [6]. While the use of crack-conforming meshes and procedural re-meshing allow for crack growth simulations with traditional finite element analysis, it is the ability of xFEM to accomplish such simulations without these cumbersome procedures that make xFEM particularly useful.

NRC currently has developed the capability to perform XFEM based PWSCC crack growth analysis in ABAQUS. Technical assistance in examining the capabilities, limitations and applicability of XFEM is required to develop a sound technical basis for performing these analyses. Additionally, NRC is interested in what other tools can be used for this type of analysis and how they compare in terms of performance and results. Technical basis development involves performing the following activities and reporting the results:

Performing sensitivity analyses to identify important factors in model parameters that can ensure accurate and repeatable XFEM results.

Thoroughly investigate the the applicability of XFEM in complex geometries relevant to commercial nuclear power components Perform study to identify and develop benchmark problems to verify ABAQUS XFEM PWSCC crack growth results.

Identify and investigate alternative, current and modern FEA tools capable of similar XFEM analysis (e.g. ANSYS, MORFEO, GRIZZLY, etc)
