Neutron source storage container

Long life waste radioactive source preparation multi-layer packaging long-term storage container includes: container body, storage cylinder located in the middle of the container body, shielding layer between the container body and the storage cylinder, and shielding pads, shielding rings, and shielding plugs matched with it from bottom to top inside the storage cylinder. The upper and lower parts of the storage cylinder are respectively equipped with shielding covers. The design of this multi-layer packaging long-term storage container takes into account the shape and size of the series of packaging tubes, as well as factors such as domestic regulations, standards, and storage status of waste radioactive sources, and has strong adaptability. The multi-layer packaging long-term storage container for the preparation of long-life waste radioactive sources can be widely used to contain and store long-life waste radioactive sources packaged in a series of packaging tubes, ensuring the long-term storage quality after packaging and reducing the risk of leakage of already packaged long-life waste radioactive sources during long-term storage.

The volume of the container body is 200L, with a wall thickness of 1.2mm or 1.5mm and dimensions of Ø 560 mm × H850 mm; One or two through holes are opened in the center of the shielding ring inside the storage cylinder, and a packaging container or two packaging containers can be placed in the middle. High density polyethylene shielding pads, shielding rings, and shielding plugs can be placed in the storage cylinder from bottom to top; The upper part of the storage cylinder is embedded with a high-density polyethylene shielding cover. The multi-layer packaging storage container is designed to hold 3.7 × 1011Bq241Am Be waste neutron sources and other long-lived waste radioactive sources. The surface dose rate of the container is ≤ 2 mSv/h, which can hold more than one waste neutron source with activity less than 3.7 × 1010 Bq241Am Be, achieving the minimum volume of stored waste radioactive sources. Easy source installation, double-layer stainless steel packaging for long-term storage safety, modular high-density polyethylene shielding to meet container surface dose rate requirements. Used for the preparation and long-term storage of long-lived hit sub sources in nuclear technology application units.
