Problems solved by technology

[0004] The existing land test platforms are unable to simulate the offshore environment firstly, and secondly, most of them are aimed at medium-sized and large-scale reactors and primary circuit simulation devices. In addition, the technical scheme of combining active and passive methods makes the design more complicated and the cost is lower. more expensive
If this type of scheme is applied to offshore nuclear power facilities, when there is a loss of energy, it is difficult for offshore nuclear power facilities to obtain other emergency energy as quickly as land facilities, and its active mode is more likely to fail, which will cause the entire protection scheme to fail

Embodiment Construction

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] See figure 1 As shown, the embodiment of the present invention provides a marine nuclear power stress suppression test platform, which includes a test device 1 and a rocking table 2 fixed below the test device.

[0030] The test device 1 includes a first housing 11 with a reactor and a primary circuit simulation device 10 inside, and a second housing 12 at least partially filled with a liquid 13 inside. The first housing 11 and the second housing 12 are connected by at least one The pipe 14 is communicated, and one end of the communicating pipe 14 located in the second housing 12 extends into the liquid 13 filled in the second housing 12.

[0031] The rocking table 2 preferably includes a pitch axis and a roll axis. When the pitch axis rolls, the test device 1 shakes perpendicular to the pitch axis; when the roll axis rolls, the test device ...

Abstract

The invention discloses a suppression test platform for ocean nuclear power, and relates to the technical field of special safety facilities for ocean small modular reactors and containments. The suppression test platform includes an experimental apparatus and a swinging table. The test apparatus includes a first shell and a second shell, a simulated reactor and a circuit simulation device with asteam generator are arranged in the first shell, and the second shell is at least partially filled with a liquid. The first shell is communicated with the second shell through at least one communication tube, and one end, positioned in the second shell, of the communication tube extends into the liquid. The test apparatus is fixed on the swinging table, and can simulate the running state under ocean conditions. When the main coolant or main steam pipeline of the ocean nuclear power platform breaks and loses water, the suppression test platform can timely suppress the pressure generated by theaccident and absorb radioactive substances, and also can suppress the pressure peak of the first shell and record the parameters of the accident to provide reference for people.

Description

Technical field [0001] The invention relates to the technical field of special safety facilities for marine small modular reactors and containment vessels, in particular to a marine nuclear power suppression test platform. Background technique [0002] The offshore nuclear power platform is a small-scale mobile nuclear power station on the sea. It is a product of the organic combination of ship engineering and nuclear power engineering. Its main goal is to supply power to offshore oil drilling platforms and islands. [0003] The offshore nuclear power platform is China's first technology, which is still in the development stage, with space constraints and pressure constraints. To improve the technology and provide data parameter support for the marine nuclear power platform, in addition to a lot of theoretical work, a lot of scientific experiments are required. Because nuclear power itself is very dangerous, its related experimental platform must be able to play a role of safety p...
