The optimum steel fiber reinforcement for prestressed concrete containment under internal pressure

Nuclear Engineering and Technology, 2022
This paper investigates the optimum fiber reinforcement for prestressed concrete containment vessels (PCCVs) under internal pressure. To achieve this aim, steel fiber, which is the most widely used fiber type in current engineering applications, is ...

Failure analysis of prestressed concrete containment vessels under internal pressure considering thermomechanical coupling

Nuclear Engineering and Technology, 2023
After a loss of coolant accident (LOCA) in the prestressed concrete containment vessels (PCCVs) of nuclear power plants, the coupling of temperature and pressure can significantly affect the mechanical properties of the PCCVs.

Benchmark VERCORS 2022: mechanical response of the prestressed concrete containment wall to ambient conditions

Acta Polytechnica CTU Proceedings, 2022
The VERCORS benchmark was developed to provide a solid experimental basis for numerical modeling of concrete containment buildings (CCBs) to extend their lifespan. The goal of the first phase of the third benchmark is to present a blind prediction of CCB’

Instrumentation of a prestressed concrete containment vessel model [PDF]

, 1995
A series of static overpressurization tests of scale models of nuclear containment structures is being conducted by Sandia National Laboratories for the Nuclear Power Engineering Corporation of Japan and the U.S. Nuclear Regulatory Commission. At present, two tests are being planned: a test of a model of a steel containment vessel (SCV) that is ...

Capacity of Prestressed Concrete Containment Vessels with Prestressing Loss [PDF]

, 2001
Reduced prestressing and degradation of prestressing tendons in concrete containment vessels were investigated using finite element analysis of a typical prestressed containment vessel. The containment was analyzed during a loss of coolant accident (LOCA) with varying levels of prestress loss and with reduced tendon area.

Research on Safety Performance of Containment Considering Influence of Prestress Loss

Yuanzineng kexue jishu, 2023
The prestress loss has a great influence on the integrity and tightness of the containment. As the service age of the containment increases, the prestress loss gradually increases. The operating experience of most nuclear power plants shows that the rate
