Abstract
Reactivity-initiated accidents (RIAs), such as the control rod drop accident (CRDA), are classified as design-basis accidents (DBAs) in the final safety analysis report (FSAR) of a nuclear power plant (NPP), and investigating these events is crucial. Therefore, point kinetics (PK) and two-point kinetics (2PK) models of a real VVER-1000 reactor have been simulated and evaluated to assess their ability to reproduce CRDA dynamics. Additionally, the simulation results of these two models have been validated against the FSAR data for a rapid-transient CRDA to examine various dynamic parameters. The reactor model was simulated in MATLAB Simulink. The model results show small deviations compared to the FSAR. Therefore, a PK model provides a reasonable degree of accuracy in the evaluation of such fast-paced incidents.
期刊介绍：
The International Journal of Energy Research (IJER) is dedicated to providing a multidisciplinary, unique platform for researchers, scientists, engineers, technology developers, planners, and policy makers to present their research results and findings in a compelling manner on novel energy systems and applications. IJER covers the entire spectrum of energy from production to conversion, conservation, management, systems, technologies, etc. We encourage papers submissions aiming at better efficiency, cost improvements, more effective resource use, improved design and analysis, reduced environmental impact, and hence leading to better sustainability.
IJER is concerned with the development and exploitation of both advanced traditional and new energy sources, systems, technologies and applications. Interdisciplinary subjects in the area of novel energy systems and applications are also encouraged. High-quality research papers are solicited in, but are not limited to, the following areas with innovative and novel contents:
-Biofuels and alternatives
-Carbon capturing and storage technologies
-Clean coal technologies
-Energy conversion, conservation and management
-Energy storage
-Energy systems
-Hybrid/combined/integrated energy systems for multi-generation
-Hydrogen energy and fuel cells
-Hydrogen production technologies
-Micro- and nano-energy systems and technologies
-Nuclear energy
-Renewable energies (e.g. geothermal, solar, wind, hydro, tidal, wave, biomass)
-Smart energy system
