Investigations on the structural integrity assessment of dome shaped roof slab of fast breeder reactor

Abstract

newline The roof slab of a nuclear reactor acts as a thermal and biological shield by preventing radiation to the environment and also, it supports various nuclear components. The massive structure of the roof slab is fabricated through the welding process. The structural integrity assessment of the roof slab is very important for the safe and reliable operation of the nuclear reactor. Structural integrity refers to the condition of a structural system and implies that the structure and its components remain intact over the intended lifetime of a structure. In the present work, systematic integrity evaluation of the roof slab is carried out under four levels by carrying out both experimental and numerical investigations.
