Liquid metal cooled fast reactors

Stieglitz, R.; Hering, W.; Wetzel, Th.; Tromm, W.

Fast spectrum reactors offer the capability for a better utilization of uranium resources. They are in principle capable to produce (“breed”) but also to transmute (“burn”) fissile materials either by means in a critical or in case of lead alloys even in a sub-critical configuration coupled with an accelerator (ADS).. Associated with the fast spectrum, they require not only a different core design but also many other technological solutions to establish a “safe reactor configuration”. Herein, especially sodium and lead (-alloy) facilitate the option to realize a compact and simple reactor design. While lead in contrast to sodium exhibits a higher neutronic efficiency associated with some often advantageous considered safety coefficients sodium cooled reactors proofed already long term operational experience and material compatibility. Irrespective of the liquid metal reactor concept chosen, liquid metals as coolant formulate new challenges with respect to thermal-hydraulics, material
choice, design and system dynamics. Furthermore, the safety demonstration demands a broad validation/verification and in some cases even a modificatio ... mehr
