ABSTRACT:
The invention relates to a process for measuring a continuous neutron flux, and to an measuring apparatus for carrying out this process. According to the invention, a probe is disposed in the neutron flux, comprising a first part defining an enclosure and a second part disposed inside the enclosure and separated therefrom by a medium whose heat conductance is known, one of said parts being made at least partially of fissile material, and the difference in temperatures between the two parts is measured at equilibrium, to deduce therefrom the power released by the fissile material, then the neutron flux. The invention is more particularly applicable to measuring the neutron flux, particularly in the core of nuclear reactors.
