Development of a Web-Based Design Evaluation Platform for Elevated Temperature Design as per ASME Section III Division 5, ASME CC-2843 and RCC-MRx

An integrated web-based design evaluation platform of HITEP (HIgh Temperature design Evaluation Program) covering the three elevated temperature design rules of ASME BPVC Section III Division 5 Subsection HB (hereafter ‘ASME-HB’), ASME Code Case 2843-2 (hereafter ‘CC-2843’) and RCC-MRx, in addition to light water reactor design rules of ASME BPVC Section III Division 1 Subsection NB (hereafter ‘ASME-NB’) has been developed. CC-2843 is recently published code case of ASME Section VIII Division 2 based on the ASME-HB procedures with explicit consideration of creep. The evaluation module of ASME-NB has been added because the low-temperature design evaluations should be also conducted for a high-temperature component depending on temperature fluctuations. The HITEP platform can be used with high reliability and efficiency for the design of high temperature pressure boundary components or piping systems subjected to high-temperature operation at creep regime in a Generation IV nuclear reactor systems, renewable plants and advanced thermal power plants. In addition to those high-temperature applications, the platform can be applied to design of Generation III+ light water reactor systems. It was shown that the platform can be reliably and efficiently used for the elevated temperature design (hereafter ‘ETD’) of pressure boundary components and piping systems. The HITEP platform has been successfully used for the ETD of pressure boundary components and piping systems of the two large scale sodium test facilities of the STELLA-2 that is currently under operation and the thermal energy storage test facility of the TESET that is under construction at KAERI.
