PROBLEM TO BE SOLVED: To suppress contamination of equipment caused by intrusion into an equipment storage domain, of contaminants generated at the cutting time by a cutting work in the equipment storage pool of a nuclear power plant. SOLUTION: The equipment storage pool 41 of the nuclear power plant is partitioned by double curtains 1, 2, to be thereby divided into a cutting pool 9 and a storage pool 8, and clean water 12 acquired by purifying pool water in the cutting pool by a purification device 6 is injected into a pocket 3 formed between the double curtains 1, 2. As for a gap of the partition generated in a sealing part between the curtains 1, 2 and the pool inner surface, the clean water 12 is run from the pocket 3 into the cutting pool 9 and the storage pool 8 via the gap, to thereby prevent contaminated water generated on the cutting pool 9 side from entering the storage pool 8 side via the gap.
