The stability of low temperature nuclear heating reactor with various subcoolings of reactor core inlet has been studied by means of simulating experiments. The thermal-hydranlic system and the data acquisition and processing system are presented. Especially, the process of realizing the simulating nuclear feedback is introduced in detail. Finally, the experimental results are discussed in the opinions of nuclear reactor physics and thermal-hydraulics. The conclusion is that the nuclear reactor can operate stably only when the subcooling of reactor core inlet is high enough.
