Abstract: The ICIS at Tianwan Nuclear Power Station is the only first in China to successfully realize reactor protection functions by linear power density and DNBR. As the kernel detectors of ICIS, NTMC plays an extremely important role. And the performance of the detector is very important to the system’s reliability. Based on the experience of TNPS, this study gives an research and development of the service life and replacement strategy for the detector. -
