Abstract: Nuclear magnetic resonance（NMR） technology play an import role in improving nuclear material stockpile circumstances and long-term security management of nuclear waste materials. Based on analyzing the circumstance factor that influence the qualitative change of the nuclear material of uranium and plutonium during their stockpile, nuclear materials detection technology with NMR method was discussed, and at the same time, moisture measurement and the water molecule moving rule in nuclear materials during their stockpile were also studied with the same method in this paper.
