Abstract

Part I - Review of Current Experience on Intermediate Heat Exchanger This part will review the different concepts of intermediate heat exchanger (IHX) that could be envisioned for HTR/VHTR applications in a range of temperatures from 850 to 950°C. This will cover shell-and-tube and compact designs (including the plate-fin concept). The review will then discuss the maturity of the concepts in terms of design, fabricability and component testing. This part will also discuss material candidates for IHX applications and will discuss specific issues that will have to be addressed in the context of the HTR design. Part II - Recommended Code Approach for Intermediate Heat Exchanger This part provides recommendations in terms of Code approach for the Intermediate Heat Exchangers envisioned for High Temperature Gas-Cooled Reactors. It will address the following: ? Recommend key features of a construction code needed to address the unique issues associated with the VHTR IHX and associated equipment ? Identify the tests which should be required to establish cyclic life or to calibrate design methods ? Identify required in-service inspection and associated NDE ? Review the adequacy of existing ASTM specifications for materials, testing, examination, etc. to determine if any new standards will need to be developed to support IHX design, fabrication, operation or inspection. ? Provide recommendations in terms of Code infrastructure.
