Structural response of large penetrations and closures for containment vessels subjected to loadings beyond design basis
The Reactor Analysis and Safety Division (RAS) and the Components Technology Division (CT) of Argonne National Laboratory (ANL) are performing analytical/numerical simulations of the response of selected large penetrations and closures, which use some type of seal or gasketed joint, for containment vessels subject to pressure and thermal loads that are beyond the design basis (BDB). The objectives of this task were to identify the methodology required to simulate the structural response of selected penetrations/closures to BDB loadings and to apply this methodology to representative penetrations/closures. Section II discusses a detailed study conducted to determine the structural response of an equipment hatch for a PWR with a steel containment vessel. The macro-deformations of the gasketed joint were computed and then used in a leakage analysis. In Section III, the methodology used to assess the structural integrity of a BWR Mark II containment head is presented. Section IV describes the approach used to obtain upper and lower bounds for the maximum allowable internal pressure and deflection for a representative bellows connection.
