No acceptance level for “robustness”
The European “Stress test“ shall demonstrate how robust the European nuclear power plants are.25 In the current discussion after the Fukushima accident the term “robustness” is used as the key expression for that what should be required. If you are robust you will never get ill even in bad weather and insufficient clothes. Robustness is meant as something that guarantees a certain kind of additional safety. But there is no definition in the international framework of safety rules or in the “Stress test” specifications, as to what additional level of safety should be achieved, what level of safety would justify saying that a plant is robust or should be backfitted considering the new requirements of the Fukushima accident or should be shut down. Therefore room will be given for incomprehensible and arbitrary assessments of the results of the “Stress test”. A transparent method must provide criteria defining what level of safety for a required basic level has to be achieved and what perhaps might be a level that justifies saying “it’s a robust plant” with additional safety features.
