摘　　要：高通量工程试验堆在运行期间,由于核功率保护仪探测器失效将直接影响反应堆的运行安全与运行质量。为此,提出了在不停堆和不影响运行需求的状态下,核功率测量仪与核功率保护仪共用一支中子探测器的使用对策。本文就此方法对核功率测量仪的电流进行研究分析,研制出一种信号适配器,经试验验证,满足反应堆运行需求,大大提高了反应堆的可运行性与经济性。During the operation of High Flux Engineering Test Reactor(HFETR),the detector failure of nuclear power protection instrument will directly affect the safety of reactor operation and operation quality of the reactor. Therefore,a strategy of sharing neutron detector of nuclear power measuring instrument with nuclear power protection instrument is put forward under the no shutdown and no influence on operation are required. In this paper,the current nuclear power measuring instrument has been studied and analyzed,and a signal adapter has been developed,which has been tested and verified to meet the needs of reactor operation requirement,and greatly improves the operation and economy of the reactor.
