For radioactive waste expected to be produced with decommissioning of nuclear power plants in the future, it is assumed there will be cases where it is difficult to apply existing storage containers, such as for sludge-like waste with high water content or waste containing salt. SFPIC (Steel Fiber reinforced Polymer Impregnated Concrete) which is polymer impregnated and polymerized in the pores of the steel fiber reinforced concrete is superior to ordinary concrete in weathertightness and chemical stabilization, so it is expected to be applicable to storage containers material. This paper presents a concept of storage containers of radioactive waste used SFPIC and various properties of SFPIC, mainly involving mechanical properties.
