A physical and thermohydraulic general estimate for the core of 25MW Lead Cooled Fast Breeder Reactor (LCFBR) has been carried out. The estimated result was compared with that of Sodium Cooled Fast Breeder Reactor (SCFBR) at the same power.

• 对25 MW电功率铅冷快增殖堆堆芯进行了物理和热工水力概算,并将计算结果与相同功率的钠冷快增 殖堆的结果进行了分析比较。
