快堆的二回路也叫中间回路,是为将具有放射性的一回路钠与给水-蒸汽回路隔开,又将一回路的热量传递给给水-蒸汽回路而设置的非放射性的钠循环系统。目前最切实可行的快堆堆型均是钠冷快堆,钠冷快堆的二回路具有如下特点:1)二回路内流动的是液态金属冷却剂钠;2)为保持钠的流动性,需设置配套的电加热系统;3)二回路的钠是高温低压;4)二回路为非放射性的;5)二回

The secondary circuit of the fast reactor, also called the intermediate circuit, is a non-radioactive sodium circulatory system provided to separate the primary radioactive sodium from the feedwater-vapor circuit and to transfer the heat from the primary circuit to the feedwater-vapor circuit. At present, the most feasible fast reactor stacks are all sodium-cooled fast reactors. The second circuit of the sodium-cooled fast reactor has the following characteristics: 1) the liquid metal coolant sodium flows in the second circuit; 2) in order to maintain the flowability of sodium, Need to set supporting electric heating system; 3) the second loop of sodium is high temperature and low pressure; 4) the second loop is non-radioactive;
