Abstract: Abstract In the nuclear power plants (NPPs), the earthquake could make a critical result because of its catastrophe risk. It is important to maintain the stability of the system without the radiation material leak from the reactor. The system dynamics (SD) is used in analysis by the random sampling quantification of the earthquake happening due to unexpected characteristics, which is one of non-linear algorithms. There is a dynamical quantification which is incorporated with the loop sequence of the time step procedures by the feedback simulations. The Power Plant Analysis has the highest value among three values including Disaster Analysis and Earthquake Analysis. For Disaster Analysis, there is the highest value on 2015. For Earthquake Analysis, there is the highest value on 2047. The highest value of summation for three values is in the year 2050, which shows the value of 28.45 times (=626/22) higher than the initial value and highest than any other value. Using SD method, the easy and logical analysis for the safety assessment is constructed by a computer code.
