Liquid metal fast breeder reactor structural materials design considerations
In summary, this paper has attempted to give a brief overview of the LMFBR, to describe its key components, to address two key structural problems, to review high-temperature materials utilized, and finally, to attempt to place bounds on expected operating conditions. The current status of materials utilization in the LMFBR might be summarized as follows: (1) With the exception of the reactor upper internals, design needs for the LMFBR can be met with currently approved Code materials. (2) Inconel 718 can potentially solve the thermal striping problems in the reactor upper internals. (3) Temperature, stress-strain levels, and design lifetime of the LMFBR push currently approved Code materials toward their limits of usefulness.
