Embodiment Construction

[0013] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0014] as attached figure 1 As shown, the present invention provides a nuclear reactor vessel suitable for high-temperature liquid carrying. The nuclear reactor vessel contains high-temperature liquid, and the support method adopts a double-slide rail hanging support system; It can slide independently and freely in two directions in the radial direction to release the thermal expansion deformation of the high-temperature container in the radial and circumferential directions; the double-slide rail hanging support system can select the type and quantity of the slide rails according to the load size, and replace the lug seat slide rails The backing plate 3 enables the container to have the ability to self-adaptively bear loads under different conditions.

[0015] The number of container hanging supports can be designed as 2, 4, 8 or more according to the lo...

Abstract

The invention discloses a nuclear reactor container for loading high-temperature liquid, and belongs to the technical field of nuclear reactor design. A supporting mode of the nuclear reactor container is a double-sliding-rail hanging supporting system, the container freely slides in the ring direction and the radial direction by the aid of a first sliding rail and a second sliding rail between a container supporting lug seat and the concrete ground respectively, and the first sliding rail and the second sliding rail are mutually independent and can be interchanged. Heat expansion freedom degrees of the nuclear reactor container in any directions are released, and safety of the nuclear reactor container is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor design, in particular to a nuclear reactor container suitable for high-temperature liquid carrying. Background technique [0002] The nuclear reactor vessel is an important equipment of the reactor, and as a pressure boundary, it is an important safety barrier of the reactor. The common suspension support of the reactor vessel is to directly connect the vessel lugs to the concrete ground through anchor bolts. However, when the high-temperature liquid-carrying container is in operation, a large temperature load will be generated due to high-temperature thermal expansion, resulting in a large stress concentration on the hanging support ear seat, thereby affecting the stability of the container support and the safety of the container. The coordination of thermal expansion and support of high-temperature liquid-carrying vessels is a key issue affecting the safety of reactor vessels. Content...
