2009年,中子导管工程组与匈牙利MIRROTRON公司工程人员合作,完成了3根冷中子导管CNGA、CNGB、CNGD的安装工作。冷中子导管系统采用匈牙利MIRROTRON公司制造的m=2超镜冷中子导管,并将其分为3个部分,按照反应堆内,提拉门内和堆外分别进行安装。堆内部分导管安装于2008年完成,CNGA、CNGD与导管中心轴线夹角为7°,CNGB、CNGC与导管中心轴线夹角为4°,安装误差小于0.5%。CNGA,CNGB导管截面34mm×154mm,CNGC、CNGD导管截面50mm×200mm,CNGA、CNGD长度2524.8mm,CNGB、CNGC长度2513mm,导管长度误差小于0.5mm,截面尺寸误差小于0.1mm。使用滚轴推拉方式,安装堆内导管适配器,
In 2009, the Neutron Catheter Engineering Group cooperated with the engineers from MIRROTRON in Hungary to complete the installation of three CNNCs, CNGBs and CNGDs. The cold neutron conduit system uses the M = 2 supercooled neutron tube manufactured by MIRROTRON, Hungary, and is divided into three sections, which are installed separately inside the reactor, inside the lifting door and outside the reactor. The inner part of the reactor was installed in 2008, the angle between CNGA and CNGD was 7 °, the angle between CNG and CNGC was 4 °, and the installation error was less than 0.5%. CNGA, CNGB catheter cross section of 34mm × 154mm, CNGC, CNGD catheter cross section of 50mm × 200mm, CNGA, CNGD length of 2524.8mm, CNGB, CNGC length of 2513mm, duct length error of less than 0.5mm, section size error of less than 0.1mm. Use roller push and pull method, install the heap catheter adapter,
