れによって構築する方法もある。(Prior art) In nuclear power plants, lead shields are installed as radiation shielding measures, and the conventional construction method for the shields is to stack lead blocks at desired times and locations each time. In addition, in order to reduce the weight of the shield, which is a large and heavy object (seismic countermeasures), there is a method of constructing the shield by inserting and removing spherical shielding material. There is also.

As a result, the structure becomes larger, which has a huge impact on economics and plant layout planning.
Limited in scale. Furthermore, in order to reduce the weight of the lotus shield (earthquake resistance), the construction method that allows spherical shielding materials to be moved in and out as needed creates space between each sphere, reducing the average density and reducing the shielding effect. When the shielding material is attached and removed, a portion of it cannot be discharged due to deformation and loss tS<lower sphere) and remains, and the structure becomes large and complicated, which has a huge impact on economics and plant layout planning.
There are problems such as limited installation locations and scale.
