Finite element structural analysis of a P.C.P.V. for a B.W.R

An interactive method has been adopted at I.S.M.E.S. in undertaking a design of a Prestressed Concrete Pressure Vessel for a Boiling Water Reactor. By means of an immediate and continuous reading of automatic graphic outputs (displacements, stresses, local safety factors etc.,), such a procedure has made it possible to identify the necessary improvements for the optimization of the structure under consideration. The structure involved consists mainly of a cylinder of constant thickness closed at the lower end with a bottom slab, and at the upper end with a removable lid slab. (Auth.)
