Abstract

PURPOSE:To shorten the work period needed for the construction of a scaffold for the inspection and examination of a bleeding pipe, a feed water heater, etc., and to lower the exposure amount, by constructing support members to be provided in a condenser of nuclear facilities in such a way that the support members cab also be used as a scaffold. CONSTITUTION:A plurality of supporting pipes 2 as the support members are welded to an upper drum 1 of the condenser, a heater 3 is installed in the lower part through supporting members 5, and a piping 4 is united to the heater 3. A plurality of the supporting pipes 2 are constructed in a form of a latticework when viewed from the top, and are also arranged one above another so that a scaffold conforming to the size stipulated in JIS is constructed. Therefore in case when periodic inspection is performed, examination or the like is carried out with respect to the bleeding pipe, the feed water heater, etc., the work for the construction of a scaffold can be omitted or simplified.

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.

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.
