REACTOR SYSTEM WITH A LEAD-COOLED FAST REACTOR

摘要

Steam generators in the form of tubular heat exchangers in which molten leadcoolant flowswithin the pipes, while the water-steam flows in a space between the pipes.The steamgenerators are arranged in separate boxes and communicate with the reactorcavity by meansof circulation conduits for raising and discharging the lead coolant. Thesteam generators andmost of the circulation conduits are arranged higher than the level of thelead coolant withinthe reactor cavity. The circulation pumps are arranged within the reactorcavity on thecirculation conduits for raising the "hot" lead coolant. Technical means isprovided forensuring intrinsic circulation of the lead coolant through the active zonewhen the circulationpumps are switched off. The specific volume of lead coolant per unit of powerof the reactoris reduced and the safety of the reactor is increased.
