Nuclear reactor vessel support structure and construction method of nuclear reactor vessel support structure |
摘要 |
A nuclear reactor vessel structure includes an inner peripheral tube-shaped steel plate, an outer peripheral tube-shaped steel plate, and an intermediate tube-shaped steel plate disposed between the inner and outer peripheral tube-shaped steel plates, and is configured to support a nuclear reactor vessel on the inner peripheral side of a tube-shaped structure with concrete placed between the steel plates. The nuclear reactor vessel structure includes a support having a tube-shaped plate disposed on the inner peripheral side of the intermediate tube-shaped steel plate, and an annular plate which protrudes to the inner peripheral side of the tube-shaped plate and to which a connection section is affixed. The support is affixed to the concrete, which is placed between the inner peripheral and the intermediate tube-shaped steel plates, by first bar members, and the support is also affixed to the inner peripheral tube-shaped steel plate by second bar members. |

1. A nuclear reactor vessel support structure which comprises an inner peripheral tube-shaped steel plate, an outer peripheral tube-shaped steel plate, and an intermediate tube-shaped steel plate disposed between the inner and outer peripheral tube-shaped steel plates and is configured to support a nuclear reactor vessel on the inner peripheral side of a cylindrical structure, wherein a space between the inner peripheral tube-shaped steel plate and the intermediate tube-shaped steel plate and a space between the intermediate tube-shaped steel plate and the outer peripheral tube-shaped steel plate are filled with concrete without a gap, the nuclear reactor vessel support structure comprising:
a support member which has a tube-shaped member in which at least a portion of the tube-shaped member is disposed on the inner peripheral side of the intermediate tube-shaped steel plate, and an annular plate which protrudes from the inner peripheral surface of the tube-shaped member to the nuclear reactor vessel and to which a connection part connected to the nuclear reactor vessel is affixed, wherein the annular plate is affixed to the concrete filling the space between the inner peripheral tube-shaped steel plate and the intermediate tube-shaped steel plate by a first bar member extending in a vertical direction and the tube-shaped member is affixed to the inner peripheral tube-shaped steel plate or the intermediate tube-shaped steel plate by a second bar member extending in a radial direction of the cylindrical structure. |
