Nuclear waste material storing and transporting barrel based on modified concrete

Abstract

The invention relates to a nuclear waste material storing and transporting barrel based on modified concrete, which comprises a barrel cover (1) and a barrel body (2). The invention is characterized in that both the barrel cover (1) and the barrel body (2) are in concrete structures, special metal wires and modifying agents are added into the concrete structures, a nuclear waste material positioning device (3) is fixed in an inner cavity of the barrel body (2), the lower part of the nuclear waste material positioning device (3) is fixed to the bottom of the inner cavity of the barrel body through a screw thread structure (4), the upper part of the nuclear waste material positioning device (3) is hanged and arranged on a cross beam (9), a lug boss body inserted into the barrel body (2) is arranged on the barrel cover (1), the step surface of the barrel cover (1) and the inner step surface in the position of a barrel opening of the barrel body (2) are matched and positioned, and the barrel cover (1) and the barrel body (2) are connected with connecting screw bolts (8) through a pressing plate (6). The invention has the advantages of simple and reasonable structure, high intensity and good radiation resistance performance.

Description

technical field [0001] The invention relates to a packaging container, in particular to an airtight container used for nuclear waste operation and storage to prevent radiation, in particular to a nuclear waste storage and transportation barrel based on modified concrete. Background technique [0002] As we all know, a large number of dirty filter elements with nuclear radiation hazards will be produced during the operation of nuclear power plants. Since such dirty filter elements will endanger human health, they must be transferred to the weak radioactive waste warehouse for long-term storage in time. In order to prevent radiation during operation and storage, dirty filter elements must be placed in storage barrels for transportation and storage. [0003] Generally speaking, the distance between the nuclear reactor and the weak radioactive waste repository is short, so it is required that the storage barrel can be stored and transported easily, and there will be no damage du...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to design a nuclear waste storage and transportation barrel with high strength and good radiation resistance for the problem that the existing nuclear waste dirty filter element has low strength, poor compactness and easy damage.
