AP1000和C系列棒位探测器优劣分析

Merit and Defect Analysis Between AP1000 and C Series Rod Position Detector

目前较多压水堆核电站中采用电感式棒位探测器,由于其处于反应堆压力容器顶部,环境较为苛刻,经过长时间的运行其故障率较高,对反应堆运行的经济性有着较大的影响。最新的非能动压水堆AP1000核电站中的棒位探测器虽然也是电感式,但因其设计原理和方案的截然不同,表现出了极其的优越性,从本质上大大提高了棒位探测器的可靠性。本文将对目前较多核电站中使用的典型电感式棒位探测器与AP1000棒位探测器的差异进行比较和分析,深入挖掘其优越性的根源。

Majority of PWR nuclear power plants use the inductive rod position detectors. Since the rod position detectors are on the top of reactor vessel which is in serious environment, the failure rate is relative high after long operation, which will reduce the economy of the reactor operation. Although the rod position detector of latest passive PWR AP1000 nuclear power plant is also inductive, the design principle and scheme is different entirely and have a lot superiority, which promote greatlythe reliability of the rod position detector. The paper will compare and analysis the differences between the typical inductive rod position detector in the majority of nuclear power plants and APIO00 rod position detector to find out the base of the APIO00 rod position detector superiority.
