２．２中国实验快堆蒸汽发生器的安全特征胡颂德在设计中国实验快堆蒸汽发生器的过程中，采取了许多有效的安全措施，使它具有良好的安全特征。它有足够的换热面；取消了换热管－管板连接结构产生的薄弱部位，改进为换热管端部直接穿过壳体并在连接处带热屏套筒的结构；采... 2.2 Safety Features of China Experimental Fast Reactor Steam Generator Hu Songde adopted many effective safety measures during the design of China Experimental Fast Reactor steam generator to make it have good safety features. It has enough heat transfer surface; cancel the heat pipe - the weak part of the tube plate connection structure, improved for the end of the heat transfer tube directly through the shell and at the junction with a thermal screen sleeve structure; .
