Abstract

The present method of evaluating the containment structures of nuclear reactors, which is based on empirical experiments and on calculations performed with codes on the consequences of hypothetical catastrophic sequences, is discussed. The trend of basing calculations and experiments on simplified models is criticised because of lack of scientific foundation. Because of their nature (simplified models and empirical procedure) it is hazardous to extrapolate the experiments to conditions which are different to those of the test. insufficient knowledge and subsequent description of the dynamic performance of the materials, especially of materials which are damaged by operating conditions under multiaxial loading insufficient knowledge of the propagation laws of stress waves in solids in both multidimensional and one dimensional conditions difficulty in defining the accuracy of the calculations performed with the codes.
