The Impact of Nuclear Engineering on Technological Improvements in Other Fields

  • D. G. H. Latzko


In over 1,000 power reactor operating-years not a single significant accident has occurred due to structural failure. To a large extent this proud and unique record may be ascribed to the achievements of nuclear structural engineering, characterized by the consistent combination of detailed and refined stress analysis, exhaustive compilation of design, offset, and emergency loads, and evaluation of all relevant modes of failure. Many in the audience will recognize the representation of these ingredients given in Figure 1, whose complete version has for many years adorned the back cover of all SMiRT (Structural Mechanics in Reactor Technology) volumes. Together they form the essence of design by analysis, the continuous success of which, however, would hardly have been possible without concomitant developments in non-destructive examination (NDE), notably with respect to in-service inspection. The combination of continuously improving methods for flaw detection and description with the advanced design precepts just mentioned has led to the first design code intended to ensure the safe operation of flawed structures. This innovation, the importance of which can hardly be overestimated, will figure repeatedly in my presentation.
