Operating temperatures for an FBR Original Research Article

Structural mechanics aspects related to operating temperatures of a typical pool type 500 MWe fast breeder reactor are discussed. The critical high temperature components are analysed in detail based on elastic, inelastic and viscoplastic deformation theories, and life is predicted in accordance with the rules of design code RCC-MR 87. Analysis indicates that the control plug is the most critical component in the reactor which limits the reactor outlet temperature to 820 K with a temperature rise of 160 K across the core.
