Auslegung und konstruktive Gestaltung eines aus Stahlgusssegmenten aufgebauten Druckbehälters für einen Kugelhaufenhochtemperaturreaktor mit einer thermischen Leistung von 3000 MW

摘要

The prestressed cast vessel is an alternative to the prestressed concrete vessel for big high temperature reactors. In this report different cast steel vessel concepts for an HTR for generation of current with 3ooo MW(th) are compared concerning their realization and economy. The most favourable variant serves as a base for the lay-out of the single vessel components as cast steel segments, bracing, cooling and outer sealing. Hereby the actual available possibilities of production and transport are considered. For the concept worked out possibilities of inspection and repair are suggested. A comparison of costs with adequate proposititons of the industry for a prestressed concrete and a cast iron pressure vessel investigates the economical competition.
