PROBLEM TO BE SOLVED: To provide a method that does not require that work space on an operation floor in a reactor building and installation space of a device or tool are moved to a turbine building or another building during periodical inspection work. SOLUTION: A work floor is installed above the drier separator pool of the operation floor in the reactor building. In that case, the work floor is installed and removed without using a ceiling crane. Space above the drier separator pool can be effectively utilized as work space and installation space of the device or tool, and the workability on the operating floor in the reactor building can be improved. Since no ceiling crane is used for the installation and removal of the work floor, the process adjustment with other work is not required, and the working amount of a pursuer can be reduced. Therefore, the work floor greatly contributes to the improvement in availability of the plant. COPYRIGHT: (C)2008,JPO&INPIT
