Development of a Program for High-Temperature Design Analysis and Defect Assessment According to RCC-MRx

Abstract

A program for a high-temperature design analysis and defect assessment has been developed for an elevated temperature evaluation according to the RCC-MRx for Generation IV and fusion reactor systems. The program, called ‘HITEP_RCC-MRx,’ consists of three modules: ‘HITEP_RCC-DBA,’ which computerizes the design-by-analysis (DBA) for class 1 components such as the pressure vessel and heat exchangers according to RB-3200 procedures, ‘HITEP_RCC-PIPE,’ which computerizes the design-by-rule (DBR) analysis for class 1 piping according to RB-3600 procedures and ‘HITEP_RCC-A16,’ which computerizes high-temperature defect assessment according to the A16 procedures. It is a web-based program, and thus can operate on a smartphone as well as on a personal computer once it is connected to the URL. The program has been verified with a number of relevant example problems on DBA, Pipe, and A16. It was shown from the verification works that HITEP_RCC-MRx with the three modules conducts a design evaluation and a defect assessment in an efficient and reliable way.

Design and construction rules for mechanical components of high-temperature, experimental and fusion nuclear installations: the RCC-MRx Code last edition

“…1. Development of rules to answer to the projects needs from the three communities: high temperature reactors (Lee et al, 2018) with initiation of adapting the RCC-MRx Code to be applicable for all GEN IV reactors (Pétesch et al, 2018b), research reactors and fusion reactors (Pétesch et al, 2017). As an example, improvement of rules to take into account irradiation, new organization of chapters addressing fast fracture and progressive deformation, completion of A3 appendix dealing with Eurofer (Muñoz .…”
