“…These SPNDs have a high sensitivity to neutrons, they also have excellent signal linearity, and their production technology is well developed. And yet, on the background of existing trends in increasing the radiation dose and operating temperature of the used in the core materials, the signal delay of the activation SPNDs and their relatively short service life [7][8][9][10] put the question: is it enough to use only inertial detectors from the point of the safety view?…”

The properties of a Compton neutron detector with the emitter of metallic Hf were studying in this work. Using the previously calculated the emitter material nuclide composition during reactor irradiation, the dependence of the emitter signal value on the irradiation time was obtained with a step of 1 year for 5 years. It is shown that the composition modification due to nuclear transmutations changes the rate of an electric charge generation in the emitter.

The work is devoted to substantiating the use of metallic hafnium as the emitter of the Compton (prompt-response) in-core detector of thermal and resonant neutrons. The main trends in the development of nuclear power engineering, which raise the interest in the use of hafnium, are considered. The known data on the behavior of both Compton and βemission self-powered neutron detectors (SPND) are generalized. The Compton SPND signal formation mechanism for the case of the irradiation by reactor-type fluxes of neutrons and gamma quanta is considered. The paper presents the calculation result of the hafnium burning-out degree for the conditions of WWER and RBMK reactors. The influence of the gamma radiation "sources", which provide the largest contribution to the electrons production in the detector is considered.
