本発明は、大型構造物の支持コンクリートの冷却に係り
、特に狭あい部での冷却方法に好適な支持コンクリート
冷却構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to the cooling of supporting concrete for large structures, and particularly to a supporting concrete cooling structure suitable for cooling methods in narrow spaces.

よびダクトを設けたことを特徴とするものである。The present invention is characterized in that the supporting concrete is provided with ventilation holes and ducts in order to cool the supporting concrete to an appropriate temperature in the narrow spaces and hot pool spaces of the supporting concrete of large structures. That is.
不発明を縦型圧力管型原子炉に採用した場合について、
以下述べる。Regarding the case where the invention is adopted in a vertical pressure tube reactor,
I will explain below.
初めに、第１図を使用して原子炉本体と支持コンクリー

冷却する必要がある。As shown in FIG. 1, the reactor main body 1 is supported by a support concrete 7, and since the reactor main body 1 is in close contact with the support concrete 7, a reactor lower space 6 and a reactor side space 3 are supported. Ventilation is blocked. As a result, the lower reactor space 6, where heat is intensely radiated from the reactor body 1, becomes a heat sink, and the supporting concrete 7 may reach a high temperature that exceeds the appropriate operating temperature of the concrete. Therefore, when the temperature becomes high, it is necessary to cool the supporting concrete 7.
次に第１．２．３図を使って支持コンクリートの冷却構
造について説明する。Next, the cooling structure of supporting concrete will be explained using Figures 1.2.3.

収納している部屋の外へ排出される。In order to cool the supporting concrete, it is necessary to connect the furnace lower space 6 and the furnace side space 3 with ventilation holes 2 to circulate air, as shown in FIG. As shown in Fig. 2, when providing ventilation holes 2 in the support concrete, avoid the sole play 1 and 80 portions that are bearing pressure strength members on the support of the reactor body, and The notch was kept small so as not to affect the The air coming out of the ventilation ports is collected at two locations by the duct shown in FIG. 3, and is discharged by a pump through the pipe 9 to the outside of the room housing the reactor body.

出するためのものである。(Air flow is shown by arrows in FIG. 1.) The duct 4 is a welded thin plate structure and is hollow inside. This duct 4 collects and ventilates the air that has passed through the ventilation port 2 from the furnace lower space 6 without wasting it, improving cooling efficiency. (If this duct is not provided, air from the top of the furnace will also be sucked in, reducing the amount of cooling air for the supporting concrete.
Cooling effect decreases. ) The support concrete IJ-to cooling structure of the present invention cools the support concrete 7 by providing ventilation holes 2 to allow air to flow over the surface of the support concrete 7, and further absorbs heat to reduce the temperature. This is for efficiently discharging air by using the duct 4.
