内部の鋼板が腐蝕するという問題があった。(Problems to be Solved by the Invention) In the pressurized water reactor shown in FIGS. 4 and 5, the steel plate flange surface (3) is removed during fuel removal and loading during periodic inspection (during the cavity filling period). Because it is exposed to the boric acid aqueous solution, red rust occurs on the entire surface, and a portion of this red rust flows into the reactor vessel (1), which is considered a problem in terms of quality control of the nuclear couplant. Further, after the cavity water is drained after the fuel is installed, many workers and many hours of work are required to remove red rust generated on the flange surface (3). In addition, many pinholes occur when applying resin lining, rubber lining, or coating with paint to various chemical storage tanks and piping in chemical plants, and after that, the chemical liquid penetrates through the pinholes.
There was a problem with the internal steel plates corroding.
