Abstract
An integrated software platform of elevated temperature design evaluation for pressure boundary components and piping subjected to high-temperature operation in the creep range has been developed. The software of ‘HITEP’ platform is capable of performing high-reliability design evaluations according to two nuclear grade design rules of ASME BPVC Section III Subsection HB and RCC-MRx, and one non-nuclear grade the Section VIII Division 2 Code Case 2843-2. The program modules were verified with a number of example problems. The HITTEP platform can be used for a reliable and efficient elevated temperature design of pressure boundary components and piping systems in generation IV nuclear systems, supercritical thermal power plants and oil refinery plants subjected to high-temperature operation in the creep range.
