Abstract

The invention discloses a nuclear radiation resistant self-healing concrete containment vessel. The containment vessel body is composed of a first steel deck, a first structural adhesive layer, a first compound fabric layer, a leaded steel capsule concrete layer, a second compound fabric layer, a second structural adhesive layer and a second steel deck successively from inside out, wherein the leaded steel capsule concrete layer is prepared by mixing concrete and leaded steel capsules. The product can effectively absorb rays so as to raise radiation resistance of the containment vessel. In addition, leakage of radioactive substances can be prevented, and strength and toughness of the product are also enhanced so as to further raise anti-seismic property.

Description

technical field [0001] The invention belongs to the technical field of anti-nuclear radiation, in particular to a self-healing concrete containment for anti-nuclear radiation. Background technique [0002] The containment vessel is the last barrier of the nuclear reactor, and its safety performance is very important. At present, according to the different constituent materials, containment can be divided into three types: steel containment, reinforced concrete containment and prestressed containment. [0003] The earliest application of containment is steel containment. However, the steel structure containment needs to use very thick steel plates, and the welding must be carried out on site, which is difficult in terms of construction period and construction technology, and the anti-nuclear radiation effect is not good, so the application is restricted. [0004] The other is reinforced concrete containment, which is: the main body is made of reinforced concrete, but steel ...
