) L ('side'): The scaffolding 10 has been moved to a higher position and the above-mentioned 1,000-yield first platform (aisle 4, 1 board) 11 has been temporarily installed, so this corporation 11''1 platform 11 is Reactor I (11-ya 6
The schedule changes daily depending on the progress of the festival, and not only is it not possible to secure a fixed entry platform 11 for a long period of time, but also when the scaffolding 10 is being erected or dismantled, a detour must be taken when the road is temporarily stopped. In addition, when the above-mentioned ridge-leveling vessel 5 is completed and the critical path of the reactor building 6 is moved to construction work, the shoring that supports the upper floor will be damaged. 4 are standing in a forest, the passage to the loading entrance 9 is obstructed, and the upper storage capacity (:t
Various piping and wiring work inside the 5-5 will be interrupted until a new passage is secured, and on the other hand, the time taken to ascend and descend the work passage and detour passages will reduce the storage capacity jjB 5- and the inside of the containment vessel 5. In order to join all the workers engaged in the work, all the actual work time was wasted, and there was a safety issue with the grace period.As a result, the construction period for the reactor room was extended. [Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and is capable of rationally reducing the number of man-hours of work for nuclear reactor engineers, and The present invention provides a method for constructing a nuclear reactor building that aims to shorten the construction process, improve the efficiency of construction work, and improve safety.
