Recommendations for the analysis and development of fire safety systems in nuclear power plants

With the population growing in our country and in the world, the need for energy is constantly increasing and, as in the whole world, our country is in search of different solutions to meet the increasing energy needs. The use of renewable energy sources in electricity networks in recent years; they have shown a rapid increase thanks to their clean, environmentally friendly nature and, most importantly, the supportive policies of the countries. The most common form of renewable energy comes from the sun. Solar energy generation has emerged as one of the fastest growing renewable sources in the world. Around 40 countries around the world have implemented the pricing law for energy production from the sun, and the growth in the energy market has increased significantly. The installation and plans of the new NPPs continue throughout the world despite the Fukushima accident in 2011. When the data were analyzed, it was seen that the reactors increased periodically from 1965 to 2010 but it was detected that there was a decrease for the first time in 2010. This is due to the reactions against nuclear energy and the efforts to improve nuclear power plants. Although the event at Fukushima Daiichi NGS was known by the public that the tsunami waves were more than predictions, but the results of calculations shows that apart from the predictions and the calculations, by causing the hydrolysis of H2O molecules it caused the release of H2 gas causing explosion. As ventilation systems designed to prevent explosion was not sufficient due to incorrect predictions, the H2 gas ,quite lighter than the air, accumulated in the upper parts, all the conditions necessary for the explosion occurred. After the explosion the security systems were damaged and they lost their function so fuel rods continued to overheat and radiation spread out to the environment, national and international security problems that can not be prevented its consequences were faced. In this study, it was revealed with the grafic and the calculations that the situation was actually a preventable accident, the calculation errors in the installation stage caused these results.
