摘要： PROBLEM TO BE SOLVED: To suppress stress corrosion cracking by lowering corrosion potential of reactor structure material. SOLUTION: Oxide existing on the surface of structure and piping of a BWR contacting reactor water is removed. Then, hydrazine is added to reactor water together with hydrogen in an operation cycle of a boiling water reactor. As hydrazine is added to the reactor water in addition to hydrogen, oxygen and hydrogen peroxide generated in the reactor are made to react with hydrazine to be water and nitrogen so that the concentration of oxygen and hydrogen peroxide in reactor water is efficiently reduced. Since oxide is removed, the effect of hydrazine to directly lower the corrosion potential of materials can be duplicated. As the results, the corrosion potential of the reactor structure materials sufficiently lowers and stress corrosion cracking can be suppressed. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for cleaning a jet pump which makes it possible to shorten a regular inspection period even if the work for cleaning the jet pump is carried out during the regular inspection period.
SOLUTION: An inlet mixer is detached from the jet pump, is moved to a fuel storage pool and is cleaned there. The mixer is moved from the pool and is set up in the jet pump. By the work for removing scale piled up on the inner surface of the jet pump in the fuel pool or a dry separator pool, the work for a regular inspection can be carried out in tandem with that for cleaning the jet pump. This makes it possible to restrain the extension of the regular inspection period.
