As opening reinforced part of SCCV receives in-plane tensile force in case of SA, stress concentration is expected to be found at its periphery. To evaluate construction feasibility under the condition that design and construction standard of nuclear power facility is applied as its reinforcing method in SCCV, scale model test was implemented simulating the reinforced part. Deformation state or stress state was inspected.
