| Abstract: | The paper summarizes the work on design criteria for liners of Prestressed Concrete Reactor Vessels (PCRVs), which has been carried out by several German institutions from 1984 to 1988 within a future High Temperature Reactor (HTR) research project.The liner is discussed as part of the concept guaranteeing the integrity of the safe enclosure of the cooling medium. Its main function is leak-tightness during the whole lifetime of the power station. On the basis of the minor safety function of the composite liner compared to that of the prestressed concrete structure with its pressure bearing function and its integrity requirements the combined action and its effects between the liner and the concrete structure has been worked out. As it is shown the composite structure ‘steel liner + anchorage + concrete structure’ guarantees a high safety of the liner.The results deal with general and special requirements to the liner-anchor-system with regard to material, design details, analytical methods, fabrication and testing. |
