Abstract Pulse filtration technology is widely used in the field of modern engineering （such as petrochemical， metallurgy， environmental protection， etc.）， but its application in the nuclear industry needs to be further developed. Using the sintered metal microporous materials of 316L and 304L stainless steel as filtration medium， and Sr（NO3）2 solution adding Al2O3 particles as simulating feed liquid， the filtration effect of the pulse filtration technology on the fine undissolved substance in the dissolving solution of nuclear power reactor was studied. The results show that the pulse filtration has a high filtration velocity of 3.50 m3/（m2·h） for the simulated material liquid. The content of undissolved substance in the filtrate is only 0.1-1.5 mg/L. The 316L and 304L stainless steel tubes used in the experiments have good filtration performance.
