Abstract
The utility model belongs to the technical field of a reactor loop system, concretely relates to reactor pressure vessel support structure. The carrying cylinder is the conical shell structure, is in the same place with the reactor pressure vessel welding in its upper end, and its lower extreme is piled the chamber through rag bolt, fastening nut and reactor and is linked together. The reactor pressure vessel top be provided with 3~6 attenuators. The utility model is suitable for a condition that the position is located pressure vessel focus below is imported and exported to the pressure vessel trunk line, and the carrying cylinder has effectively born reactor body load, and the attenuator has avoided pressure vessel to take place to topple.
Description
Technical field
This utility model belongs to reactor-loop systems technology field, is specifically related to a kind of reactor pressure vessel supporting structure.
Background technology
Reactor pressure vessel is one of key equipment of whole nuclear power plant reactor and primary Ioops system, is the important component part of pressure boundary.In nuclear power station, in-pile component, core components, CRDM, heap roof construction etc. are fixed and supported to reactor pressure vessel；In containment, in order to effectively fix reactor pressure vessel, it is ensured that the safe operation of whole reactor, it is necessary to arrange the supporting structure of reactor pressure vessel.Conventional pressure vessel main pipeline is imported and exported position and is above pressure vessel center of gravity, and when pressure vessel is not tumbled, supporting form all adopts pedestal to support.
Summary of the invention
The purpose of this utility model is in that to provide a kind of reactor pressure vessel supporting structure, the problem that can not support main pipeline import and export position lower than the pressure vessel of pressure vessel center of gravity to solve tradition pedestal to support.
For reaching above-mentioned purpose, technical solution adopted in the utility model is:
A kind of reactor pressure vessel supporting structure, supporting cylinder is conical shell structure, and its upper end and reactor pressure vessel weld together, and its lower end is linked together by foundation bolt, clamp nut and reactor cavity.
Described reactor pressure vessel top is provided with 3～6 antivibrators.
Having the beneficial effect that acquired by this utility model
The present invention is applicable to pressure vessel main pipeline import and export position and is positioned at the situation below pressure vessel center of gravity, and supporting cylinder effectively carries reactor body load, and antivibrator avoids pressure vessel and topples.The present invention supports cylinder at lower end bearing pressure vessel, meanwhile, in order to prevent pressure vessel from toppling over, is provided with 3～6 antivibrators on pressure vessel top, retrains its radial displacement.
