According to the present situation that key nuclides in primary coolant can not be monitored in real-time ,various influencing factors of rapidly measuring nuclides were analyzed ,and the improved key nuclide method was proposed based on the decay prop-erties of nuclides .T he results indicate that the speed and accuracy of measuring short-lived fission nuclides are improved by packet-segmentation measurement with portable γspectrometer .
