Closing the PWR fuel cycle with a molten-salt incinerator

摘要

We present a detailed study of a non-moderated Molten-Salt (MS) reactor, when operated asrna transuranium elements burner, closing the nuclear fuel cycle of a PWR reactor. We evaluaternits neutronic characteristics and main safety parameters, both in the first years of operation andrnin equilibrium fuel cycle. Influence of the carrier salt composition, neutron flux and feed compositionrnon the burner performance are also studied. Our results show, that non-moderated MSrnburner can be operated as a critical burner reactor without fertile support in an acceptable rangernof parameters. The temperature feedback coefficients are relatively low, but we show that theirrnfurther optimization is possible.
