Damper-free support system for modular high temperature air-cooled pile pressure casing

Abstract

The invention relates to a non-damper supporting system of module-type high temperature air-cooled reactor pressure vessel that is belonged to device technology field. The invention is used to solve the antimony between the unreliability of big damper and the high reliability of actor. The invention supplies a safe and reliable machine to take place of damper supporting system. It includes the first main bearing bracing, the second main bearing bracing, the first side direction bracing and the second side direction. Using the invention, the effective bearing and earthquake-resistant behavior would be ensured, and the fabrication cost is low.

Description

technical field [0001] The invention relates to a support system for a pressure shell of a modular high-temperature gas-cooled reactor, and belongs to the technical field of nuclear equipment. Background technique [0002] Since both the reactor pressure vessel and the steam generator pressure vessel are very tall and heavy devices, large dampers are used in the design of the supporting structure to allow thermal expansion between components and to relieve the seismic load zone by the dampers during an earthquake coming shock. [0003] The disadvantage of the support system using the damper is that the damper is prone to failure and requires high operation and maintenance, and once the damper fails, the reactor pressure vessel and the steam generator pressure vessel may tilt, stretch or compress The middle part connecting the two pressure shells—the hot gas conduit pressure shell, causes excessive compressive stress or tensile stress, which endangers the safety of the press...

[0003] The disadvantage of the support system using the damper is that the damper is prone to failure and requires high operation and maintenance, and once the damper fails, the reactor pressure vessel and the steam generator pressure vessel may tilt, stretch or compress The middle part connecting the two pressure shells—the hot gas conduit pressure shell, causes excessive compressive stress or tensile stress, which endangers the safety of the pressure boundary and affects the safe operation of the reactor

Also, large dampers are expensive
