Optimal repair solution for reactor
DC-303 required detailed stress and strain analysis by applying the finite
element method. The calculation has been performed step by step, i.e. by
gradually increasing the complexity of the model as based on previous results.
All relevant effects are taken into account. Besides the optimal repairing
solution, the experimental verification of strains and stresses during the hydro
test has been suggested.
