PROBLEM TO BE SOLVED: To provide a tense installation method of a safety rope in various facilities, such as, a spent fuel pool in a nuclear power plant capable of safely executing various works by avoiding generation of a state of dropping of an operator by mistake, by keeping at all times a tense state without loosening the safety rope, when arranging the safety rope for a safety countermeasure as an alternative means around various facilities, such as, a nuclear reactor connected to the spent fuel pool or a storage pool, such as, a steam separator in the nuclear power plant in the opened state by removing handrail. SOLUTION: This tense installation method of the safety rope in various facilities, such as, spent fuel pool in the nuclear power plant comprises a combination of processes for erecting poles at each prescribed interval around various facilities, such as, the spent fuel pool in the nuclear power plant; inserting the safety rope into each ring attached to each upper end of the poles; fixing one-end side of the safety rope after insertion; and winding the other-end side of the safety rope on a storage reel via a tensioner for backward-movement prevention.
