PWR advanced-RCC, which increase control rod worth adopting B_4C with enriched ^<10>B as RCC absorber and the B_4C/Ag-In-Cd axially hybrid design, is developed to enhance flexibility of large MOX or high enriched fuel loading capability. And the adoption of a double cladding structure result in improvement of wears resistance and rationalization of inspection. The adoption of the advanced-RCC results in the reduction of the construction costs and the maintenance costs for the significant reduction of the number of the RCCs in PWR. To verify these new designs of the advanced-RCC, some experiments of control rod flow induced vibration, RCC drop characteristics, control rod worth, the irradiation characteristics are performed. It is confirmed the advanced-RCC will be adopted in APWR in the near future.
