Abstract
Power operations for secure performance are investigated using non-linear algorithm. The object of the simulation is to find the safe operation with safeguard for the life-extension of the operations. The network effect of the game theory is used for the quantification which is incorporated with the Monte-Carlo method. The characteristics of the nuclear power plants (NPPs) are analyzed by the designed occurrence value as the refueling factor (RF) and the safeguard measures factor (SMF) which are used for the basic element. The random sampling for the event frequency is used by the characteristics of network effect method like the zero-sum quantification, because it is impossible to expect the time of terror incident exactly. Three kinds of considerations are basic elements as the nuclear fuel, system, and safeguard properties which are organized as an aspect of safeguard considerations. The maximum value of secure operation is the 13.0 in 14th month and the minimum value is 1.0 in several months during 10 years. Hence, the stability of the secure power operation increases 13 times higher than the lowest value in this study. The conclusions give that the secure operation is changeable in the designed NPPs.
