PROBLEM TO BE SOLVED: To provide a method for maintaining a suppression chamber (SC) which makes it possible to maintain painted surfaces of the SC, without having to implement partial repair painting work repeatedly, year after year. SOLUTION: This invention makes the method for maintaining the SC, where a submerged face of it is repaired and painted with pool water staying includes a precipitate and deposit removal process for removing the precipitate in the SC and the deposit adhering to the wall surface, a water jet cleaning process for sucking and pressurizing the pool water and spraying it over the wall surface, after the precipitate and deposit removal process and a painting process for applying paint to the wall surface, after the water jet cleaning process. Accordingly, significant decrease in the frequency of refinishing repair is obtained, and the preservative maintenance cost for the wall surface painting of the SC is restrained.
