Nuclear Power Plant Prestressed Concrete Containment Vessel Structure Monitoring during Integrated Leakage Rate Testing Using Fiber Bragg Grating Sensors [PDF]
Applied Sciences, 2017 As the last barrier of nuclear reactor, prestressed concrete containment vessels (PCCVs) play an important role in nuclear power plants (NPPs). To test the mechanical property of PCCV during the integrated leakage rate testing (ILRT), a fiber Bragg ...

ANALYSIS OF PRESTRESSED CONCRETE CONTAINMENT VESSEL (PCCV) UNDER SEVERE ACCIDENT LOADING [PDF]
Nuclear Engineering and Technology, 2008 This paper describes the nonlinear analyses of a 1:4 scale model of a prestressed concrete containment vessel (PCCV) using an axisymmetric model and a three-dimensional model. These two models are refined by comparison of the analysis results and with testing results.
