DESIGN STUDY OF Pb-Bi- AND NaK-COOLED SMALL DEEP SEA FAST REACTORS

摘要

The liquid lead-bismuth eutectic (Pb-Bi) has good compatibility with water, which is different from sodium. It is expected that the Pb-Bi could be used as a coolant of the deep sea fast reactor (DSFR). Physics analysis of the Pb-Bi-cooled small reactor cores with and without inner control rods performed using the computer program of a neutronics code system (SRAC95) shows that Pb-Bi is suitable for the coolant of small reactors as well as NaK.
