Abstract
The invention relates to an anti-vibration device for a nuclear power plant reactor. The anti-vibration device comprises a reactor shell, a reactor containment, balanced balls and a support frame; the anti-vibration device is characterized in that the support frame used for holding the reactor is arranged at the bottom of the tumbler reactor containment on a basin in the reactor shell; a suppression pool is arranged at the bottom of the containment; and at least three balanced balls are evenly distributed around the inner side wall of the containment on the suppression pool. The housing of the reactor shell is composed of a lining of a steel shell and a concrete layer tightly attached outside the steel shell. In the invention, as the reactor is arranged in the tumbler reactor containment and at least three balanced balls are evenly distributed around the inner side wall of the containment, the vibration can be effectively prevented and weakened. The anti-vibration device for the nuclear power plant reactor has the advantages of novel design, reasonable and simple structure and low cost.
Description
Technical field
The present invention relates to a kind of vibration abatement that is used for nuclear power plant reactor.
Technical background
Nuclear reactor is uranium element 235 neutron bombardment heavy nucleus, and fission heavy nucleus neutron continues the bombardment fission and releases energy, and takes heat energy out of with chilled water, produces high pressure steam, the pushing turbine generating.The energy of 1 kilogram of uranium fission release equals 2700 tons of coal combustions.But can produce a large amount of radiating matters in the fission, Fukushima nuclear power station generation earthquake, cooling system is ruined in shake, and residual heat of nuclear core is more and more warmmer, blasts.The present sees that No. 1 unit of Japan shatters, and reveals objectionable impurities, the harm environment.Therefore nuclear reactor being placed in the containment of shockproof damping effectively is the most urgent demands of people.
Content of the present invention
The present invention seeks to people provide a kind of not only can shockproof effectively damping, and novel in design, rational in infrastructure, simple, the vibration abatement that is used for nuclear power plant reactor that cost is low.
The present invention includes pile envelope, containment vessel, balance roller, bracing frame; It is characterized in that: place the bracing frame of putting reactor is housed bottom the roly-poly type containment vessel on the Bao Penchi in the pile envelope; The containment bottom is constrain pond, and one week of containment madial wall on the constrain pond evenly is placed with at least three balance rollers.
The housing of described pile envelope is made up of the box hat internal layer concrete layer outer with being close to box hat, and the housing inner bottom part is constrain pond.
The housing of containment vessel is made up of the box hat internal layer concrete layer outer with being close to box hat.
Effect of the present invention
1, the present invention is because of placing reactor in the roly-poly type containment vessel, again because of one week of containment madial wall evenly is placed with at least three balance rollers, and therefore can shockproof effectively damping.
2, the present invention is novel in design, and rational in infrastructure, simple, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment 1:
