Abstract

Abstract: The excore nuclear instrumentation system (NIS) is an important means of reactor power monitoring. However, during the commission and operation phases, it is deeply troubled by noise interference problems due to the weak signal and long-distance transmission. For the NIS noises, there are various reasons but few related studies, which brings great difficulties for troubleshooting and solving work. During the commissioning process of the AP1000 excore NIS, the noise problem is more prominent, and the means of investigation and disposal are typical. Based on the experience in engineering and commissioning, the common noise sources of NIS are concluded, and the general fault location and suppression methods are summarized. Finally, the maintenance recommendations for the excore NIS of subsequent units are proposed.

Key words: nuclear instrumentation system (NIS); electromagnetic compatibility (EMC); neutron flux measurement; distributed control system (DCS)
