合い部の構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the basic structure of a nuclear reactor body made of steel, and in particular,
This invention relates to the structure of the connecting part between the top of the reactor body foundation and the reactor body support skirt.
１製型の原子炉本体の基礎において、頂部にコンクリー
ト層を持つ構造の問題点を図面に基づき説明する。We will explain the problems of the structure with a concrete layer on top of the foundation of the reactor body made in Type 1 based on drawings.

締付固定されている。The foundation l of the reactor body has a structure in which cylindrical steel plates 1a and Ib are arranged inside and outside, and a vertical lip (not shown) is provided inside. The top of the steel reactor main body foundation 1 is fastened to the skirt 3 of the reactor pressure vessel 2, a bearing plate 4, and a concrete layer 5 by means of foundation bolts 6 and nuts 6'.
現状の構造では、ＦＬＰＶスカートに加わる水平力は、
アンカボルトを介し、コンクリートに伝達されるのであ
るが、コンクリートがアンカボルトの支圧に対し圧壊し
てしまう可能性がある。In the current structure, the horizontal force applied to the FLPV skirt is
The force is transmitted to the concrete via the anchor bolts, but there is a possibility that the concrete will collapse under the bearing pressure of the anchor bolts.
本発明の目的は、原子炉本体の基礎頂部における、ＲＰ
Ｖスカートから、原子炉本体基礎への水平力の伝達を信
頼性のあるものとし、現地での据付、加工全容易なもの
とすることにある。The object of the present invention is to
The objective is to ensure reliable transmission of horizontal force from the V-skirt to the foundation of the reactor body, and to facilitate installation and processing on site.
本発明の特徴は、原子炉本体の基礎頂部にコンクリート

頂部への水平力の伝達をコンクリートに期待せず、リン
グ状のトラス構造を設けることによって、その伝達を信
頼性の高いものにすると同時にトラス構造採用により、
現場据付、加工を容易にしたことである。The feature of the present invention is that when a concrete layer is provided on the top of the foundation of the reactor body, a ring-shaped truss structure is provided instead of expecting the concrete to transmit horizontal force from the RPV skirt to the top of the foundation of the reactor body. This makes the transmission highly reliable, and at the same time, by adopting a truss structure,
This makes on-site installation and processing easier.
以下本発明の実施例を図面に基づいて説明する。Embodiments of the present invention will be described below based on the drawings.
第１図において、原子炉圧力容器は、原子炉本体の基礎
ｌ上に、基礎ボルト５によって支持され、その廻りに原
子炉じゃへい壁７が配置されている。In FIG. 1, the reactor pressure vessel is supported by foundation bolts 5 on a foundation l of the reactor body, and a reactor barrier wall 7 is arranged around it.
原子炉本体の基礎頂部は、第４図に示すようにコンクリ
ート層５があり、その上に、原子炉圧力容器のスカート
３が支持されている。また、原子炉圧力容器のスカート
３は、トラス８によって、原子炉じゃへい壁基部と接合
されている。At the top of the foundation of the reactor body, as shown in FIG. 4, there is a concrete layer 5, on which the skirt 3 of the reactor pressure vessel is supported. Further, the skirt 3 of the reactor pressure vessel is joined to the base of the reactor wall by a truss 8.

ラスの全体配置を第３図に示す。This top part is fixed to the top steel plate IC by the foundation bolt 6 with a nut 6', and the bearing plate 4 is fixed to the top steel plate IC by the foundation bolt 6'.
After adjusting the level, weld it to the base of the truss 8'fr bearing plate 4 and the reactor wall 7,
After pouring the concrete, the reactor pressure vessel 2 is set up. The overall arrangement of the truss is shown in Figure 3.
このように構成される原子炉本体の基礎頂部は、原子炉
圧力容器のスカートより伝達される荷重のうち、水平力

。従って、アンカボルトの水平力伝達時にコンクリート
に加わる支圧により、コンクリートが圧壊することがふ
せげる。The top of the base of the reactor body configured in this way transfers the load due to horizontal force, which is transmitted from the skirt of the reactor pressure vessel, directly to the reactor pressure vessel from the skirt of the reactor pressure vessel, without passing through the anchor bolts 6. It is transmitted to the furnace wall 7. Therefore, the concrete is prevented from being crushed by the bearing pressure applied to the concrete when the horizontal force is transmitted by the anchor bolt.
