The study of aeroball system for measuring 3D neutron flux distribution in reactor core

The study of aeroball system for measuring 3D neutron flux distribution in reactor core 1 first-author 1 1 Institute of Nuclear Energy Technology, Tsinghua University, Beijing 100084 Institute of Nuclear Energy Technology, Tsinghua University, Beijing 100084 Aeroball system is attractive in several aspects because it can easily transport the map of neutron flux distribution to be measured from incore to outside of a reactor vessel. However, before the aeroball system is put to practical use in the heating reactor, there are four topics that have to be further studied. They are the stability of the activated positions, enhancement of signal/noise (S/N) ratio, distributed control and data-acquisition system and on-line neutron flux distribution reconstruction. Besides describing the reasons for them, this paper gives out the theory, concept and solution about the first two topics and it is helpful to give the possibility to enhance the reactor-power.
