本発明は、大型構造物の据付方法に関し、特にタンク型
高速増殖炉の原子炉容器の据付方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a large structure, and particularly to a method for installing a reactor vessel of a tank-type fast breeder reactor.
高速増殖炉は、一般に液体ナトリウム等の液体金属を冷
却材とし、液体金属が循環する冷却系は一次冷却系と二
次冷却系とに分れている。Fast breeder reactors generally use liquid metal such as liquid sodium as a coolant, and the cooling system in which the liquid metal circulates is divided into a primary cooling system and a secondary cooling system.
そして−次冷却系と二次冷却系の液体金属は。And - the liquid metal in the secondary cooling system and the secondary cooling system.
中間熱交換器において熱交換関係にあるいわゆるタンク

炉容器の中に収納するものであり、それなりの特長を有
するものであるが、原子炉容器が非常に大形なものにな
る。A so-called tank-type fast breeder reactor, which has a heat exchange relationship in an intermediate heat exchanger, has a core in which fuel is loaded, as well as a circulation pump and an intermediate heat exchanger that constitute the primary cooling system, all in one reactor vessel. Although it has certain features, the reactor vessel becomes extremely large.
更に評言すればタンク型高速増殖炉の原子炉容器は、実

その重量も千トンに近くなるのでその据付にも特別の工
夫を要する。Furthermore, the reactor vessel of a tank-type fast breeder reactor, in a practical or demonstration reactor, has a diameter of more than 20 meters and weighs nearly 1,000 tons, so special measures must be taken to install it. It takes.
加えて、原子炉容１ｉ（はゾ椀状をなす。）の外側には
、万一の冷却材洩れに備えて原子炉容器を取り囲むはゾ
同形の保護容器が設けられ。In addition, on the outside of the reactor vessel 1i (which is bowl-shaped), a protective vessel with the same shape as the reactor vessel is provided to surround the reactor vessel in case of coolant leakage.
更に両容器共遮蔽璧に囲まれた格納室内に垂下支持され
ることから、前記据付工事の困難さは甚だしいものとな
る。Furthermore, since both containers are suspended and supported within a storage chamber surrounded by a shielding wall, the installation work becomes extremely difficult.
例えば、原子炉容器の底部を複数の仮ジヤツキで持上げ
ようとすると２Ｍ子炉容器の支持反力が局部的になって
その部分を予め補強しておく必要が生じ、その重量や製
作費を更に増加させる問題がある。For example, if you try to lift the bottom of the reactor vessel with multiple temporary jacks, the support reaction force of the 2M sub-vessel will be localized, making it necessary to reinforce that area in advance, which will further increase the weight and manufacturing cost. There is a problem of increasing
又、仮ジャックを保護容器上には設置できないから、保
護容器に穴を設け、最後にその穴を塞く゛必要があり、
その作業や検査に多大の時間を要する。Also, since the temporary jack cannot be installed on the protective container, it is necessary to make a hole in the protective container and then plug the hole.
The work and inspection require a lot of time.
本発明は、前記した事情に鑑みなされたもので、外側の
保護容器を設置した後、保護容器の底部に膨張袋を仮置

法を提供するものである。The present invention was made in view of the above-mentioned circumstances, and after installing an outer protective container, an expansion bag is temporarily placed at the bottom of the protective container, a reactor vessel is placed on top of the expansion bag, and the expansion bag is then inflated. It provides a method for lifting, positioning, and installing a nuclear reactor vessel.
以下２本発明を実施列に基づいて説明する。The following two aspects of the present invention will be explained based on the implementation series.
図において、コンクリート遮蔽壁１，２及び床８は既に
打設され、格納室６が形成されている。In the figure, concrete shielding walls 1 and 2 and a floor 8 have already been cast, and a storage room 6 has been formed.
遮蔽壁１．２の上部には、又内向きの棚７が形成されて
いる。別の場所例えば工場内で製作された椀状の保護容
器Ｓは、クレーン等の運搬て吊り降され、上部開口外縁
のフランジ１１が棚７の上に置かれる。An inwardly directed shelf 7 is also formed in the upper part of the shielding wall 1.2. A bowl-shaped protective container S manufactured at another location, for example, in a factory, is transported by a crane or the like and suspended, and the flange 11 at the outer edge of the upper opening is placed on the shelf 7.
次いで流体すなわち空気の供給ホース１８の先についた
膨張袋すなわちエアバッグ１Ｂをしぼんだま５保護容器
９の底に置（。その際、ホース１８の先端は外へ出して
おく。Next, the inflatable bag or air bag 1B attached to the end of the fluid or air supply hose 18 is deflated and placed on the bottom of the protective container 9 (at this time, the end of the hose 18 is left outside).
次いで、椀状の原子炉容器１７（保護容器９と同様別の

を支持すると共に原子炉容器１７を蓋するものである。Next, a bowl-shaped reactor vessel 17 (fabricated at a different location like the protective vessel 9) is temporarily placed in the protective vessel 9, and the roof slag 19 is carried into the upper part of the containment chamber 5, and its outer edge is Place it on shelf 7. The roof slag 19 is connected to a circulation pump of the primary cooling system and an intermediate heat exchanger (none of which are shown).
It supports the reactor vessel 17 and covers the reactor vessel 17.
そして最後にホース１８からエアバック１６に加圧空気
を送給して膨らませ、容器ｔｙを持ち−Ｅげ、容器１７
の上縁とルーフスラグ１９のＴ−縁とを整列させ、溶接
により両者を結合する。Finally, pressurized air is supplied from the hose 18 to the air bag 16 to inflate it, and the container ty is held -E and the container 17
The upper edge of the roof slug 19 is aligned with the T-edge of the roof slug 19, and the two are joined by welding.
この作業により、原子炉容器１７はルーフスラグ１９を
介して遮蔽壁１，２の棚７から垂下支持されたこととな
り、据付が完了する。エアーバック１５より空気を抜き
、除去する。With this operation, the reactor vessel 17 is suspended and supported from the shelves 7 of the shielding walls 1 and 2 via the roof slag 19, and the installation is completed. Let the air out of the air bag 15 and remove it.

つ短時間に据え付けることができる。As explained above, according to the present invention, the reactor vessel is lifted by inflating an expansion bag such as an air bag, so that excessive local stress is not generated in the reactor vessel or the protective vessel, and special processing is not required for these. Since the expansion bag can be deflated and easily removed, a large reactor vessel can be installed easily and in a short time.
