Zuverlässigkeit & Sicherheit
Neue technologische Ansätze müssen, bevor sie im Kraftwerksmarkt eingesetzt werden können, einen Grad von Zuverlässigkeit besitzen, der gleich oder sogar besser als der Stand der Technik ist. Im Zuge der Entwicklungen neuer Verbrennungstechnologie zur Erweiterung der Brennstoffflexibilität, für die CO2 Abscheidung sowie für regenerative Stromerzeugung auf der Basis von Wasserstoffspeichern werden grundlegendes Verständnis, verbesserte Auslegungsregeln und schärfere Berechnungswerkzeuge benötigt, um die Herausforderungen hoch-reaktiver Brennstoffe zu meistern. Ungeachtet der politischen Diskussion über Kernkraftwerke werden weltweit stetig neue Anlagen errichtet. Die fortlaufende Verbesserung der Risikoforschung und der Unfallvermeidungsstrategien in Verbindung mit internationalem Austausch wird deshalb immer noch als essentiell erachtet, um das Schadenspotenzial einer steigenden Zahl an kerntechnischen Anlagen zu minimieren. Am Lehrstuhl wurde über 30 Jahre experimentelle und numerische Kompetenz in den Gebieten der Thermohydraulik und der Detonationsforschung aufgebaut, die erforderliche Grundlagendaten und Modelle an die öffentliche Hand liefert.
