本発明は、復水器に係)、特に、原子力設備に新設する
のに好適な復水器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a condenser, and particularly to a condenser suitable for new installation in nuclear power facilities.

成されている。In the condenser in conventional nuclear power facilities, as shown in Figure 1, the upper body IK inside the turbine condenser is welded with a plurality of boat members 2 in consideration of vacuum strength, and the heater 3
.. The pipe 4 and the heater support member 5 are incorporated into the structure.
このような従来の復水器において、抽気管、給水加熱器

の足場を使用して作業を実施している。In such conventional condensers, when performing periodic inspections and inspections of bleed pipes, feed water heaters, etc., scaffolding materials (usually
Scaffolding was constructed by assembling multiple layers of Alken pipes, and the work was carried out using this scaffolding.
しかしながら、このような従来の足場構築方法にあって
は、足場材の取付不具合およびサポート部材の追加等で
、復水器内部での作業時間が長くなり、必要以上の放射
能被爆が起ってしまう危惧があるという欠点があった。However, with this conventional method of constructing scaffolding, work time inside the condenser becomes longer due to improper installation of scaffolding materials and the addition of support members, leading to unnecessary radiation exposure. The drawback was that there was a risk of it being lost.
また、復水器内部への機材搬入についてはマンホールの
サイズが基準となり、足場材の搬入寸法にも制限が発生
することになるため、工期は一層長期化する。In addition, the size of the manhole will be the standard for bringing equipment into the condenser, and there will be restrictions on the dimensions of scaffolding materials, which will lengthen the construction period even further.
本発明の目的は、前記従来技術の欠点を解消し、復水器

本発明は、前記目的を達成するため、復水器内部に設け

ように構築し九本のである。In order to achieve the above-mentioned object, the present invention is constructed so that a support member provided inside the condenser can be used as a scaffold in advance.
以下図面に即して本発明の詳細な説明する。The present invention will be described in detail below with reference to the drawings.

いる。2 and 3 show an embodiment of the present invention, in which a large number of support pipes 2 as support members are welded to the upper body 1 of the condenser, and A heater 3 is installed via a support member 5, and a pipe 4 is connected to the heater 3. As shown in FIG. 3, the multiple support pipes 2 are arranged in a lattice shape when viewed from above, and are assembled in multiple stages as shown in FIG. is building.
本実施例によれば、JIS規格標準サイズの足場があら

It can be applied not only to condensers for nuclear power facilities, but also to condensers for thermal power facilities.
以上説明するように、本発明によれば、復水器の停止期
間を短縮化することができる。As described above, according to the present invention, the condenser stop period can be shortened.
