Abstract: The safety of spent fuel pools in nuclear power plants is a very important safety issue for nuclear power plants, and the performance of neutron absorbing materials is related to the safety of spent fuel pools. The hanging piece of the same kind of neutron absorbing material is placed in the spent fuel pool, and the reliability of the neutron absorbing material in the spent fuel pool can be evaluated by periodically checking the performance of the hanging piece. The development of our B4C_Al alloy coupon testing equipment is expected to play an important role in assessing the safety of spent fuel pools in nuclear power plants. The test equipment firstly establishes a standard curve by using the standard samples with known surface density of 10B, and then the surface density of the sample would be calculated according to the neutron transmittance, thereby reflecting the neutron absorption capacity of the spent fuel pool storage material, and providing a technical means for the safety inspection of reactor spent fuel pools. The equipment is the first boron aluminum alloy coupon testing equipment in China. The development of this equipment lays the experimental foundation for the future non-destructive inspection of domestic boron-containing neutron absorption materials.
