The roof slab of a nuclear reactor supports all the components and sub-systems. It needs to resist the seismic loads in accordance with load-carrying criteria. The static stress analysis of the reactor roof slab reveals that high-stress concentration was present in the pump penetration shell (PPS) that supports the primary sodium pump. This paper presents an assessment of collapse load and the optimization of the pump penetration shell through the reliability approach, accounting for material non-linearity, geometrical non-linearity and randomness in loading. In addition, the load-carrying capacity of PPS was determined considering two different materials: IS2062 and A48P2. The design of experiments (DoE) was formulated considering the flange angle and flange thickness as parameters. An empirical model for load function was formulated from the results of the collapse load obtained for various combinations of design parameters. The above function was used to perform the reliability-based geometry optimization of the PPS of the roof slab.
