Abstract: When a glove box is used for centralized sampling of liquids and gases in a nuclear power plant, the sampling pipelines filled with radioactive liquid become radiation hotspots. Due to the complicated structure of the glove box pipeline and high internal humidity, the lead or flexible lead shield will be hardened due to oxidation, affecting the operability of the glove box pipeline. Adding micron-level metal powder to the silicone rubber matrix can form a new type of shielding material that takes into account both softness and protective effect, and will not oxidize and harden for a long time in high humidity air. This paper compares the calculated and tested values of the shielding effect of tungsten rubber in the reference radiation field to verify the reliability of the calculation method. In this paper, a shielding device suitable for hotspots in complex pipelines is designed, using tungsten rubber as the shielding material. The effect of different thickness tungsten rubber shielding devices on the dose rate in the personnel operating space is simulated and analyzed, so as to give a recommended plan.
