Variance Decomposition Sensitivity Analysis of a Passive Residual Heat Removal System Model

In-containment Refueling Water Storage Tank (IRWST): In-containment passive long-term recirculation means Passive Residual Heat Removal (PRHR) utilizing Passive Residual Heat Removal Heat Exchanger (PRHR HX): Automatic Depressurization System (ADS): Internal IEs: Three major types of IEs

Safety of a nuclear power plant and its related systems are the first key issue to assure experts and the public of the safe operation of the plant. The AP1000 reactor is provided with passive safety systems which require no operator actions due to utilizing only natural forces such as gravity, natural circulation and compressed gas to achieve the safety function. In this paper the core damage ...

Variance decomposition-based sensitivity analysis via neural networks

This paper illustrates a method for efficiently performing multiparametric sensitivity analyses of the reliability model of a given system. These analyses are of great importance for the identification of critical components in highly hazardous plants, such as the nuclear or chemical ones, thus providing significant insights for their risk-based design and management. The technique used to quan...

Sensitivity Analysis of MPSIAC Model

MPSIAC is currently known as an appropriate method to measure sediment ofWatershed basins of the country while there has not been any sensitivity analysis so far forthis method. In this study, required data for MPSIAC model were gathered from six basins;Amame-Kamarkhani, Kand-Golandok, Tang Kenesht (from two different references), Nojian(from three different references), Pegahe sorkh katvand (f...

Monte Carlo simulation-based sensitivity analysis of the model of a thermal-hydraulic passive system

Thermal–Hydraulic (T–H) passive safety systems are potentially more reliable than active systems, and for this reason are expected to improve the safety of nuclear power plants. However, uncertainties are present in the operation and modeling of a T–H passive system and the system may find itself unable to accomplish its function. For the analysis of the system functional failures, a mechanisti...
