Advanced Gas Cooled Nuclear Reactor Materials Evaluation and Development Program: Program Work Plan

摘要

Economics, availability and deployment strategy have focused FY1982-1983 HTGR Process Heat/Reformer (PH/R) evaluation efforts on modular reactor systems up to 250 to 300 MW/sub t/ in size and monolithic reactor systems up to 2240 MW/sub t/ in size; both types of reactor systems are of the 950 exp 0 C direct cycle (DC) configuration. Because of economic considerations, the modular reactor is expected to permit major-component replacement at 50,000 hours to 100,000 hours operation, whereas a longer duration of service will be required for component replacement for the monolithic reactor. The materials test program will be geared to obtaining essential design data for one alloy (Alloy 800H) for the near-term and shorter-life applications to 850 exp 0 C in the modular reactor, continued studies of Inconel 617 for use at temperatures to 950 exp 0 C, and continued screening of US, European and Japanese alloys to select additional candidate materials for the longer-term long-lived modular reactor components or monolithic reactors. It is absolutely necessary that the material test program not only provide data related to manufacture and structural design but also data which ensures component reliability. (ERA citation 08:009843)
