【摘要】 在钠冷快堆的余热排出设计中,通常采用独立热交换器放置热池的非贯穿独立余热排出系统。本文提出将独立热交换器贯穿冷热钠池的贯穿式余热排出系统设计方案,在全厂断电事故下,对两种布置方式下的余热排出特性进行了对比计算。结果表明两种方案均能有效导出堆芯余热,但贯穿式设计对堆芯的冷却效果更好。更多还原

【Abstract】 In the decay heat removal design of sodium-cooled fast reactors,the direct reactor auxiliary cooling system(DRACS) with direct heat exchangers(DHX) placing in the hot pool is usually adopted.In this paper,a DRACS design with DHX arranged penetrating through hot pool to cold pool is proposed.Under a station blackout accident,the characteristics of decay heat removal of two DRACS designs were calculated and compared.The results show that two designs can remove the residual heat effectively,while the penetrating design can cooling the core better.更多还原
