Problems solved by technology

[0004] (1) The structural strength of the container is low, and it is easy to deform in accident conditions, resulting in the leakage of radioactive substances
[0005] (2) The space that can be used to store the liquid material is small, and the space utilization rate is low, so it is difficult to meet the storage or transfer of a large volume of radioactive material liquid

Embodiment 1

[0033] This embodiment discloses a split-type tube bundle trough, which adopts a split-type structure design, that is, includes an inner container and an outer frame, and the inner container and the outer frame are two mutually independent structures. The inner container is used to store reflections that are prone to critical reactions (critical reactions refer to the release of new neutrons during the nuclear fission process, too many neutrons will cause criticality, resulting in unstable operation of the nuclear reactor, and even the danger of explosion in severe cases) The outer frame is sleeved outside the inner container to support the inner container.

[0034] Specifically, the inner container includes a container body 1 , a tube bundle 2 and a top cover 4 . The container body 1 is preferably a cylindrical container, the top cover 4 is set on the container body 1, and the top cover 4 is provided with a through hole, the shape and size of the through hole match the shape ...

Abstract

The invention discloses a split-type tube bundle tank. The split-type tube bundle tank comprises an inner container and an outer frame, wherein the inner container comprises a container body and tubebundles, and the container body is used for storing radioactive material liquid; the plurality of tube bundles are arranged in the container body, and a neutron poison unit is arranged in the tube bundles; and the outer frame is arranged outside the container body and is used for supporting the inner container. The split-type tube bundle tank provided by the invention is high in structural strength and high in storage volume utilization rate, and storage safety of the radioactive material liquid can be improved.

Description

technical field [0001] The invention belongs to the technical field of radioactive material processing, and in particular relates to a split tube bundle groove. Background technique [0002] Nuclear facilities such as nuclear power plants and reprocessing plants produce a large amount of radioactive substances during operation or maintenance, especially plutonium-containing feed liquid, which is highly radioactive and prone to critical reactions. The storage safety of plutonium-containing feed liquid is related to the safe and stable operation of the entire nuclear power plant or spent fuel reprocessing plant. At present, the storage method for this kind of radioactive material prone to critical reaction is generally to place neutron poison in the storage container to prevent critical reaction. [0003] At this stage, the container used to store radioactive materials that are prone to critical reactions adopts an annular groove structure design, that is, the outer annular s...
