Structural Analysis of Fuel Handling System

Abstract

The purpose of this paper has three aspects: (i) to review "why" and "what" types of structural analysis, testing and report are required for the fuel handling systems according to the codes, or needed for design of a product, (ii) to review the input requirements for analysis and the analysis procedures, and (iii) to improve the communication between the analysis and other elements of the product cycle.

The required or needed types of analysis and report may be categorized into three major groups: (i) Certified Stress Reports for design by analysis, (ii) Design Reports not required for certification and registration, but are still required by codes, and (iii) Design Calculations required by codes or needed for design.

Why and what types of analysis and report are required or needed?

As part of the Component Design Document (per CSA N285 series, References 1 to 4) or the Design Output Documents (per ASME Boiler and Pressure Vessel Code, Article NCA-3550, Reference 5), types of analysis, testing and report required for structural integrity achievement for fuel handling components and supports are summarized below: (1) Certified Stress Reports for design by analysis (together with Certified Review of Design Report by the owner or his designee) are required for design registration for the following 'components and supports: (a) Class 1, 1C and 4 components and their supports. Input requirements for structural analysis include: (b) Class 2 and 2C vessels designed to ASME NC-design, code classification, loadings, and 3200. . jurisdictionary boundary. Examples of structural analysis for the fueling machine head and support (c) Class 2 or Class 3 components designed to structure are given. Service Loading greater than design loading.

For improving communication between the structural analysis and the other elements of the product cycle, some areas in the specification of design requirements and load rating are discussed.
