Reliability-Based Design Optimization of Pump Penetration Shell Accounting for Material and Geometric Non-Linearity

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