The application of a base isolation to nuclear systems should be considered in lots of view points of operation at the stage of design before construction. Those points includes protection and maintenance of isolators for a seismically isolated nuclear power plant. The methodology suggested in this paper is applicable for any type of isolators in which an isolated structure part is easily replaced and confined pressure can be easily controlled with a height-adjustable part. The height-adjustable part being adjusted by suppling or discharging fluid therein or therefrom
