ア床面からほぼ３０．下の位ｍｌ二める。The reactor building of a boiling water nuclear power plant consists of a primary containment trough that is installed outside the primary containment vessel that surrounds the reactor pressure vessel, and a secondary containment trough that also serves as a secondary containment trough outside that. It has reached the livelihood of the living body and the roof, which is composed of the roof, and the tube on the floor of the room on the upper floor of the moths in the bush wall FI reactor building, and the top floor surrounded by the next time -time bush wall. A part of the plug is a concrete S bush plug, which shields radiation from the top of the vessel to the top floor of the reactor.The top floor is used as a shield when stopping and inspecting the reactor. This is the laydown space for plugs, secondary containment vessel lids, Otoshi reactor pressure vessel lids, etc., and is also the place for exchanging fuel, and is called the operation floor.The floor below the operating floor. The floor has a thickness of more than aO,, and I! is thicker than the lower floor 6 due to structural conditions.Fi is the source of radiation on the operating floor 62.During normal operation, the fuel pool is When the reactor is shut down and inspected, the spent fuel in the reactor is added to the steam dryer in the 6-2 core fuel, the steam dryer in the W & No. storage bit, and the radiation from the steam and water separated rice, but this will eventually occur. The water surface is also shielded by a sufficient thickness of water, and the water level is approximately 30 ml below the operating floor floor level.

めにＦｉ。Therefore, under normal conditions, the operation floor I: is a strong radiation l.
Since there is no such thing as IOl, there is no need for the walls and ceiling C2 on the operating floor to have a shielding function. However, if we assume a coolant loss accident, for example,
-Next, rare gas leaking from the containment vessel leads to the lower floor through the openings of the Nth stage, elevator, and train to the operation floor. Therefore, assuming an accident, it is necessary to thicken the walls of the operation floor in order to reduce radiation exposure inside and outside the nuclear couple plant site.
The wall is set between t30 and 70-. Sarazui: Fi to reduce the influence of Sky Kuyain through the ceiling on the side of the site.

度である。The non-invention was made in consideration of the above-mentioned circumstances, and the purpose is to provide a nuclear reactor IIAIjA in which the contribution of radiation from the operation floor to the inside and outside of the site is reduced.0 [Summary of the invention] Nuclear reactor A nuclear reactor IIaJiEl having a structure that allows the top floor of the building to be airtightly isolated from the floor below. 1 m, certain 0 [Example of the Invention] An embodiment of the present invention will be described below with reference to the drawings. Reactor of the present invention The building consists of several floors above ground and underground surrounded by a reinforced concrete floor and a square, with the upper floors serving as operation floors. The floor and wall thickness of each floor is based on the radiation edge from the powder on each floor.
The dimensions are determined so that the equipment can withstand earthquake force, etc. Normally, the floor surface with a light scent is about 300 yen.

比較してきわめて小さい。If we imagine a hypothetical accident, the radioactivity released from the reactor would be distributed from the primary containment vessel! Alternatively, cable noise may leak into the secondary containment vessel from a relatively airtight part that penetrates the living body. On the operation floor, -
Since there is no penetration from the next containment vessel, there is a possibility that radioactivity will enter through the floors below, but in the reactor building of the present invention, it is airtightly isolated from the floors below, so the operation floor can be heard. Second, there is no possibility of radioactivity entering. In this situation, the stairwells and elevator rooms are places that are higher than the floor of the operation floor, but the volumes of these places are extremely small compared to the volume of the operation floor.

The area is 50 m x 50 m, the height is 18 m, and the free space is approximately 4.

Therefore, the radiation wit rate in and around the power plant premises in the event of a hypothetical accident will be approximately. In addition, if you cover the walls of the stairway and elevator room, the dose rate will further decrease.For example, if you cover the walls of these rooms with a wall of 300 wl, the dose rate will be reduced by 11 ’ rate is further reduced.Compared to conventional plants, f11100

上し、さらに資源の節約にもなる。In addition, compared to conventional plants, the thickness of the ceilings and walls of the control room, emergency response room, etc. can be made thinner, and the center of gravity of these buildings can be lowered, making it possible to reduce the risk of complete collapse in the event of an earthquake. This improves the efficiency and also saves resources.
