は少ない方がよい。Conventionally, a nuclear reactor containment vessel, such as an opaque type reactor containment vessel, has been constructed as shown in FIGS. 1 and 2. That is, 1 is the main body of the containment vessel, which is made of, for example, reinforced concrete, and has pressure resistance and radiation shielding ability. A liner 2 is stretched over the inner surface of the containment vessel body 1 to provide airtightness. The inside of the containment vessel main body 1 is divided into upper and lower sections by a diaphragm floor 3, with a dry well 4 formed in the upper part and a sagress chamber chamber 6 formed in the lower part. A pedestal 6 is erected within the containment vessel body 1, and the reactor pressure vessel 1 is installed and swung on the pedestal 6. A heat shielding wall 8 is provided surrounding the reactor pressure vessel. The upper end of this heat shield ms is supported by the containment vessel main body 1 via support members 9...
The heat shielding wall 8 is configured to support the horizontal load applied to the heat shielding wall 8 in the event of an earthquake or the like. By the way, these support members 9 have conventionally been provided in a horizontal direction between the outer periphery of the upper end of the heat shielding wall 8 and the inner peripheral surface of the containment vessel body 1. The rail 1 for running the hoist crane, which is used for rounding, attaching and removing the main steam isolation valve 10, etc., had to be provided below the support member 9. By the way, a certain distance is required from the front rail 11 to equipment such as the main steam isolation valve 10 for hoisting these equipment, rounding the work, and installing air conditioning ducts. However, if the rails 11 were disposed below the support members 9 as described above, the containment vessel body 1 would be correspondingly higher, which was disadvantageous in terms of earthquake-resistant design. In addition, at the attachment part between the support members 9... and the containment vessel main body 1, a relatively large support fitting 12 is embedded in the containment vessel main body 1 as shown in FIG. It is necessary to disperse and support the large horizontal load acting through the containment vessel main body 1. (9) In such a concrete reactor containment vessel, a flange member 14 for attaching the upper cover 13 must be formed separately, and this must be attached to the containment vessel main body IKgIL. By the way, 14 such flange members are subjected to a large upward load when the internal pressure of the reactor containment vessel increases. For this rounding, it is necessary to embed a large fitting 15 in the upper part of the containment vessel body 1 and attach the flange member 14 to this fitting 15. However, embedding such large fittings 15 and support fittings 12 complicates the reinforcement structure of the chest girth, so it is better to have fewer large fittings embedded in the containment vessel main body 1.

によって逃がされるように構成されている。A plurality of support members 115 are provided upwardly from the upper end surface of the heat shield 108, and the upper ends of these support members 115 are connected to the earth wall of the containment vessel main body 101, for example, as described above. It is embossed on the mounting bracket 114. Incidentally, reference numeral 116 is a mounting metal fitting for attaching these supporting members 115 to the upper end of the heat shielding wall 1011, and is embedded in the upper end of the heat shielding wall 10m. As shown in Fig. 5, these support members 115 are arranged in a nine-truss shape continuous in the circumferential direction, and are configured to withstand loads in the circumferential direction. Therefore, the horizontal load acting on the upper heat shielding wall 108 is the support member 115 located at a position perpendicular to the direction of the load.
It is configured to be received by and transmitted to the containment vessel main body 101. In addition, the support member 115...

The applied circumferential load is transmitted to the containment vessel body 101, but the radial load is not transmitted to the containment vessel body 101. Accordingly, the structure is such that thermal deformation of the heat shielding wall 1011 is relieved by sliding these sliders 117b in the radial direction.

が簡単となシ、建築コストを低減することができる。Further, an annular rail 118 is provided at the upper part of the containment vessel main body 101, and a hoist crane (not shown) used for installing and removing equipment such as the main steam isolation valve 111 is attached to this rail 118. An embodiment of the present invention configured as described above is configured to run along the reactor pressure vessel 10fl during an earthquake.
8 is transmitted to and supported by the containment vessel main body 101 by support members 115 located perpendicular to the direction of this load. Since the support members 115 are arranged upward from the upper end of the heat shield wall 108, there is no obstruction between the outer peripheral surface of the heat shield wall 108 and the inner surface of the containment vessel body 101. There are no components. Therefore, the rail 118 is connected to the containment vessel main body 1.
01, the height of the containment vessel body 10 can be lowered by that amount, and this 'containment vessel body 1
The earthquake resistance of 01 is improved. Moreover, in this way, the support member 1
15 are provided protruding from the upper part 7j, so that the upper ends of these support members 115 are positioned around the upper opening of the containment vessel main body 10.1. Therefore, these supporting members 115・
The mounting bracket A114 that receives the load of... is the flange member 11
Since only one such mounting fitting 114 is required, the structure of the containment vessel main body 101 is simplified and the construction cost can be reduced.
なお、本発明は必らずしも上記の一実施例には限定され
ない。Note that the present invention is not necessarily limited to the above embodiment.
たとえば支持部材取付用の取付金具とフランジ部材取付
用の取付金具は必らずしも共用しなくてもよい。For example, the mounting bracket for attaching the support member and the mounting bracket for attaching the flange member do not necessarily have to be used in common.
また、支持部材は必らずしも上記−実施例の如きトラス

。As mentioned above, the present invention includes a containment vessel body made of concrete,
Nine cylindrical heat shielding walls are housed in the containment vessel body and are provided surrounding the nine reactor pressure vessels, and the upper part of this heat shielding wall is connected to the soil wall of the containment vessel body and is continuous in the local direction. It is equipped with a supporting member assembled in a truss shape.

The space between this heat shielding wall and the containment vessel body can be used effectively by installing it at the top of the containment vessel, and the height of the containment vessel body can be reduced by that amount, improving earthquake resistance. The effect is great.
