Numerical modeling and simulation of a prestressed concrete containment vessel
Annals of Nuclear Energy, 2018Abstract This work addresses the numerical modeling and simulation of prestressed concrete containment vessels (PCCVs) using the damaged-plasticity model for concrete and accounting for its interactions with the steel materials (i.e., the steel rebars, liner plate and prestressed tendons).

Mechanical analysis for prestressed concrete containment vessels under loss of coolant accident
Computers and Concrete, 2014LOCA (Loss Of Coolant Accident) is one of the most important utmost accidents for Prestressed Concrete Containment Vessel (PCCV) due to its coupled effect of high temperature and inner pressure. In this paper, heat conduction analysis is used to obtain the LOCA temperature distribution of PCCV.

The containment vessel of a nuclear power plant is the last barrier to prevent nuclear reactor radiation. Aseismic safety analysis is the key to appropriate containment vessel design. A prestressed concrete containment vessel (PCCV) model with a semi-infinite elastic foundation and practical arrangement of tendons has been established to analyze the ...

Abstract The leakage of the internal gas could cause structural expansion and cracking of the containment structures in nuclear power plant (NPP). Predicting the ultimate internal pressure resistant capacity and investigating the failure mechanism for the containment structures above the design-basis accident pressure is of great importance.

After years of operation, the safety of the prestressed concrete containment vessel (PCCV) structure of Nuclear Power Plant (NPP) is an important aspect. In order to detect the strength degradation and the structure deformation, several sensors such as vibrating wire strain gauge, invar wires and pendulums were installed in PCCV.

Analysis and application of prestressed concrete reactor vessels for LMFBR containment
Nuclear Engineering and Design, 1978Abstract An analytical model of a prestressed concrete reactor vessel (PCRV) for LMFBR and the associated finite element computer code, involving an explicit time integration procedure, is described. The model is axisymmetric and includes simulations of the tensile cracking of concrete, the reinforcement, and a prestressing capability.
