Based on the correlation between the nuclear pump laser intensity and the incident neutron fluence rate, the theoretical feasibility of the nuclear pump laser neutron detector in the active region of the reactor is discussed. Starting from the nuclear pump laser mechanism, - nuclear pump laser 3He Ar Xe gas system energy deposition density and the intrinsic efficiency of the laser in-depth theoretical study. A more complete theoretical model is proposed to discuss the system of neutron flux rate response function and The detection sensitivity changes with working hours, demonstrating the theoretical feasibility of the neutron detection system
