【 摘 要 】

The components of the intermediate heat transfer loop will be subjected to conditions that may produce time dependent deformation, corrosion and erosion. High temperature strength may also be an issue with many components. A stress analysis will be performed on the intermediate heat exchanger of the PCHE type and the implications on material requirements will be determined. Potential materials of construction will be identified and evaluated in light of the stress analysis and the available creep data. A concentric or annular pipe design for carrying both the hot and cold fluid streams in the intermediate loop will be modeled to determine the temperature drop between the NGNP and the hydrogen production facility. This design will be compared to separate piping for the hot and cold fluid streams. Finally two designs for the process heat exchangers will be evaluated for catalytic and thermal effectiveness. All the evaluations mentioned above will be performed for both high pressure helium and liquid salt as the heat transport media. Also, materials and materials issue swill be discussed with regard to the evaluations.
