The paper investigates the ability to learn from an aircraft accident as the opportunities for learning diminish with the decline in the accident rate. A safety compromising case is studied as the processes of aircraft accident intervention and recovery can degrade the ability of an aircraft accident investigation process to enhance aviation safety by revealing accident causation. In the case s...

Work-related accidents as one of the most prominent indicators of safety and health in the industry play an undeniable role in developing and improving the quality of industrial health management. Therefore, their accurate analysis on a large scale is essential. To provide controlling solutions, we aimed to investigate the causes of occupational accidents in Iran for 10 years (2007-2017). At fi...

Understanding a reliable description of the heat transfer in molten pool with three-layer configuration is inevitable for design severe accident mitigation measures research reactors, such as IVR-ERVC. However, investigations on thick lower metallic layer are scarce. Thus, further studies highly required, based previous light water reactors. This study conducts numerical simulation during accid...

Abstract Nuclear power has special safety requirements and must be generated on the premise of nuclear safety. It is necessary to forecast abnormal situation system equipment as soon possible, so we can control accident beforehand prevent risk caused by failure accident. At present, pre-accident method in plant mainly relies subjective experience personnel. In contrast, intelligent forecasting ...

Background: The radionuclides released by the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident 9 years ago are still being monitored various research teams and Japanese government. Comparison of different surveys’ results could help evaluate exposure doses mechanism radiocesium behavior in urban environment area. In this study, we clarified relationship between land use temporal changes a...
