A nuclear instrumentation system of a nuclear power plant and positioning method therefor. The system comprises: a source range (SR) channel, an intermediate range (IR) channel, and a power range (PR) channel. Each channel comprises a detector disposed on the periphery of a pressure vessel. Each of the detectors of the PR channel and the IR channel comprises several fission chambers, and the detectors of the PR channel and the IR channel share some of the several fission chambers. Some detectors choose to use fission chambers, and therefore have improved anti-Gamma radiation capability, anti-noise performance, and anti-electromagnetic interference performance. Moreover, sharing fission chambers decreases the number of detectors and reduces subsequent workload for detector installation and positioning. Furthermore, increasing the redundancy of some channels improves system reliability. "Bucket-suspending type" installation allows easy detector installation and pull-out operations and protects ...
