Steel containments for nuclear reactor plants

Creators

Description

In order to secure even in extreme cases, steel containments for nuclear reactor plants based on a concrete foundation but partly standing free, a suggestion is made to connect the built in parts and pipelines inside the containment via numerous straining screws to the concrete foundation. The straining screws should be at right angles to the surface of the containment and a distance be kept to the concrete by a flexible packing. The invention is described taking the example for PWR.

Abstract (German)

Um Stahlsicherheitsbehaelter fuer Kernreaktoranlagen, die auf einem Betonfundament aufliegen, aber z.T. freistehen, auch in Extremfaellen zu sichern, wird vorgeschlagen, die Einbauten und Leitungen im Innern des Behaelters ueber eine Vielzahl von Spannschrauben mit dem Betonfundament zu verbinden. Die Spannschrauben sollen rechtwinklig zur Oberflaeche des Sicherheitsbehaelters orientiert sein und durch eine nachgiebige Packung gegenueber dem Beton distanziert sein. Am Beispiel eines DWR wird die Erfindung beschrieben. (HP)
