Monitoring of Prestressed Concrete Containment Vessel at Temelin Nuclear Power Station, Unit 1

摘要

The state of stress and deformation of the prestressed concrete containment vessel (PCCV) at the Temelin NPP was monitored by various systems of measurement. A comprehensive analysis of the PCCV was performed, including seismic analysis. The concrete of the PCCV was also monitored long-term in the laboratory. The measurement results were compared with the results of computer modelling and laboratory tests. This paper describes the PCCV structure, specifically the secondary tensioning; the structural integrity test; the system of measurement and comparisons; and the analysis of PCCV.
