Problems solved by technology

[0006] In view of this, the present invention aims to propose a reactor pressure vessel support plate structure, which solves the problem that the reactor pressure vessel will sway and sway due to external factors.
In order to improve the anti-seismic capability of the reactor pressure vessel, it is necessary to increase the thickness, support and other protective measures to increase the cost of the equipment. A

Abstract

The invention provides a reactor pressure vessel support plate structure. The structure comprises a support plate and a cylindrical pipe capable of being welded with a reactor pressure vessel. The support plate is in sliding connection with the upper end surface of the cylindrical pipe, the upper end surface of the support plate is provided with a lubricating structure with a lubricating materialembedded in the structure, and the cylindrical pipe is arranged on the lubricating structure in the sliding mode. Less seismic acceleration or ocean sway impact load is transferred to the pressure vessel according to the connection structure between the support plate and the cylindrical pipe and the principle of sliding shock absorption, so that the acceleration of the pressure vessel is greatly reduced, seismic auxiliary facilities for the pressure vessel can be reduced, the cost of the pressure vessel can be greatly reduced, and the seismic capacity of the reactor pressure vessel can be improved.
