この発明は高速増殖炉等の原子炉建屋の構造に関するも
ので、内部の機器および建物の耐震設計の合理化を図っ
たものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the structure of a nuclear reactor building such as a fast breeder reactor, and is intended to rationalize the seismic design of internal equipment and buildings.
高速増殖炉では原子炉支持位置の床応答スペクトルを低
減することは、プラント合理化のため重要な課題となっ
ており、近年新しい開発テーマとしてその実現のために
様々な研究がされている。In fast breeder reactors, reducing the floor response spectrum at the reactor support position is an important issue for plant rationalization, and in recent years various studies have been conducted to realize this as a new development theme.
例えば建物を支持岩盤中に埋め込む方法あるいは建物直
下に免震装置を設置し建物ごと免震構造にする方法など
が研究されている。For example, research is being carried out on methods such as embedding buildings in supporting rock or installing seismic isolation devices directly beneath buildings to create a seismic isolation structure for the entire building.
上述の建物免震構造を採用した場合、建物の地震力は大
幅に減少されるため、上部および外周建物構造を鉄骨造
とすることが可能となる。When the above-mentioned building seismic isolation structure is adopted, the seismic force of the building is significantly reduced, so it becomes possible to use a steel frame structure for the upper and outer building structures.

残ることになる。This increases the degree of freedom in selecting construction methods, and can be a rationalizing factor, such as shortening the construction period and reducing the weight of the building compared to conventional reinforced concrete construction. However, the parts requiring shielding related to radioactive materials will remain as reinforced concrete structures.

果が得られない。Therefore, when a building is made of steel and reinforced concrete, the building sections must be separated to facilitate earthquake behavior and stress transmission. In this way, the floor response spectrum when two structures are erected on one foundation slab (see Figure 1 (a)) is sufficient, as shown in Figure 2 compared to a monolithic building made of reinforced concrete. No significant reduction effect can be obtained.
この発明は上述のような問題点を解決することを目的と

制振ダンパー３で吸収するようにしている。This invention is aimed at streamlining the seismic design of equipment and buildings in nuclear reactor buildings such as fast breeder reactors. A connected vibration damper 3 is installed between the steel frame structure (reinforced concrete structure may also be used; the same shall apply hereinafter) of the building part and the roof and other building outer peripheral parts 2,
Due to the difference in movement between the two, the vibration energy generated during an earthquake is absorbed by the connected vibration damper 3.

つ床応答スペクトルの低減が可能になる。By connecting the reinforced concrete reactor periphery 1 and the steel frame building periphery 2 with a connecting vibration damper 3, the effects of mutual vibrational interference and the vibrational energy absorption effects of various dampers reduce earthquakes in each structure. Forces are reduced and a reduction in the floor response spectrum is possible.
