Abstract

The invention relates to a reactor internals suitable for an ocean nuclear power platform, which comprises a cylinder body, a reactor internals arranged in the cylinder body and supported on the cylinder body; the pressing elastic ring is supported on the top of the reactor internals, the pressing elastic ring is located in the cylinder body, and the pressing elastic ring can be compressed in the axis direction of the cylinder body; and the top cover is installed at the top of the cylinder body, and the bottom of the top cover abuts against the pressing elastic ring, so that the pressing elastic ring generates pre-tightening force in the axis direction of the cylinder body. According to the reactor internals suitable for the ocean nuclear power platform, the pretightening force of the pressing elastic ring can act on the reactor internals, the pressing elastic ring can compensate machining and assembling errors of the reactor internals, and axial displacement of the reactor internals under the temperature difference and additional force possibly generated by hydraulic impact can be compensated; and enough pressing force is provided for reactor internals.

Description

technical field [0001] The invention relates to the technical field of safety facilities of nuclear power plants, in particular to a reactor internal component suitable for marine nuclear power platforms. Background technique [0002] The marine nuclear power platform is an offshore floating nuclear power plant. The marine nuclear power platform can provide long-term, efficient and safe power supply for undeveloped islands, offshore drilling platforms, seabed exploration and deep-sea exploration workstations in vast sea areas. [0003] In related technologies, the marine nuclear power platform has a reactor pressure vessel containing nuclear fuel, and the reactor pressure vessel is generally provided with reactor internals to accommodate and support the core. Equipment such as its related components are combined to realize the reactor function. However, due to processing and assembling errors in the process of manufacturing or assembling the reactor internals, the reactor i...
