Design-by-Stress Analysis per ASME BPV Code, Section III, Division 1: Class 1, 2 and 3 Components (Virtual Classroom)

This course provides guidance for applying the requirements of the latest¹ Edition of Mandatory Appendix XIII Design by Stress Analysis of Section III, Division 1 of the ASME Boiler and Pressure Vessel Code for Class 1, 2, and 3 components (vessels, pumps, valves, and piping) for installation in nuclear power facilities.

Participants review the basis for design by stress analysis and how design by stress analysis can be used in conjunction with the design rules for Section III Division 1 Class 1, 2 and 3 components in Subsections NB, NCD² respectively; stress classification and processing finite element analysis results using stress classification cut lines; as well as Class 1 allowable stress intensities per Appendix XIII, and Class 2 and Class 3 allowable principal stresses per Subsection NCD when not referencing Appendix XIII and when referencing Appendix XIII.

Additionally, participants delve into the process of evaluating stresses caused by pressure, mechanical and thermal loading combinations and how those evaluations are performed in accordance with the requirements of the hopper diagram in Appendix XIII; evaluation of Level A and Level B cyclic loadings (shakedown and fatigue); evaluation of special stress limits such as pure shear, torsional shear, shear due to loads near edges, triaxial stresses, compressive stresses, buckling beyond external pressure loading, seismic loads, brittle fracture; and design reports.

By participating in this course, you will learn how to successfully:

• Identify the basis, history and failure modes driving the requirements of Appendix XIII as it applies to Class 1 components and how it selectively applies to Class 2 and Class 3 components.
• Apply ASME BPV Code, Section III, Division 1, Mandatory Appendix XIII: Design by Stress Analysis Hopper Diagram and Stress Classification to the appropriate stress intensity or principal stress criteria in Subsection NCD.
• Determine when to apply Design by Stress Analysis for non-bolts, for bolts, and threaded structural fasteners and when Design-by-Rules takes precedent over Design by Stress Analysis.
• Apply the Appendix XIII Design by Stress Analysis for evaluation of Class 1, 2, and 3 components and the unique aspects for vessels, pumps, valves and piping; and interaction of design rules with fabrication, examination, and testing rules of Subsection NB and Subsection NCD.
• Identify the differences for applying Design by Stress Analysis to Class 1, 2, and 3 components.
• Apply Appendix XIII requirements with solid element and plate-shell element finite element analysis of pressure, mechanical and thermal loadings.
• Apply the process, analysis, and qualification for the Design, Operating Levels A, B, C and D and Test loadings and explain how results are reported in a Section III Division 1 Component Design Report.
• Determine when and how to apply Limit Load and Plastic Analysis
