摘　　要：通过合理组合涂硼计数管和γ补偿电离室,在计算机辅助分析和改进涂硼技术的基础上,研制能够覆盖反应堆中子通量的全量程中子核测量探测器。该探测器保持了计数管和电离室的灵敏度,可减少堆外探测孔道和探测器数量,为源区中子测量的准确性和可靠性提供冗余通道,确保反应堆临界安全和核安全。The whole range neutron nuclear measurement detector（NMD） was developed by combining boron coating counter and γ-compensated ionization chamber,under computer assistant analysis and improving boron-loaded technique.The detector has the same sensitivity of counter and ionization chamber,can reduce the number of exploration hole and detector,and gives redundancy for veracity and dependability of source region neutron measurement,and insures reactor critical safety and nuclear safety.
