Excessive gamma rays will be emitted when a nuclear power plant is under the refueling overhaul, leading to a certain number of hotspots. To meet the shielding requirements of these hotspots, a new type of flexible shielding material with a “sandwich structure” was developed. This kind of material has been adopted in a mega-kilowatt pressurized water reactor (PWR) nuclear power plant as the first demonstration project. Based on the characteristics of the new flexible shielding material, the process design program of the product application was founded, and the new material was compared with the traditional lead shielding material. At last, the installation and removal time together with the shielding effect were analyzed according to the first demonstration application.
