Abstract

Abstract

In order to realize the effective acquisition of data required for deep subcritical rod worth calculation, the overall architecture and key modules of deep subcritical rod worth measurement electronics have been researched and designed. The characteristics of the key modules have been tested through reactor test. The results show that the designed deep subcritical rod worth measurement electronics can effectively measure the detector signal transmitted through about 200 m cable. The pulse signal has a stable waveform width and a proper signal-to-noise ratio. The measured high voltage plateau characteristic curve can provide an effective reference for the high voltage selection of the detector. The measured discrimination characteristic curve is stable, from which the neutron component in the detector signal can be effectively obtained.
