In concrete reactor vessels of high temperature reactors many cavities with different diameters are arranged. The design of the closures for such cavities is an important problem in the detail engineering. A draft based on using prestressed concrete as a material is presented for closures with high diameter values. The influence of tendon forces, creep and shrinkage, pressure, etc, on stresses, stress distribution, and deformation are proved by a finite element analysis and the results are pointed out. A short outlook of further development is given. 12 refs.
