Abstract: Taiwan is located in an active seismicity region with more than thousands of events occurring every year in average. On the other hand, this small inland is a home of around 23-million people, and nearly 20% of the daily activity is powered by the three existing nuclear power plants (NPPs), with a new one under construction located in Northeastern Taiwan, which is officially referred to as the Longman nuclear power plant, also known as the "fourth NPP" or the "NPP 4" locally. However, when seeing the seismicity in the last 110 years, one can not help but wonder how the decision-making process finalizes such a location for such a critical structure. As a result, the underlying scope of this study is to discuss the site selection with the fundamentals of engineering decision-making given three prior objectives: maximizing the design safety, minimizing the construction cost, and minimizing the risk. Given the NPP 4 following the same earthquake-resistant design in Taiwan, the construction cost is very likely the same as building other NPPs, but owing to the high earthquake potential in Northeastern Taiwan, the risk should be higher than those located in North Taiwan and South Taiwan. Therefore, without further information, possibly confidential, being available at this moment, we must conclude that the NPP 4 site in Taiwan is not an optimal location with a scientific, engineering decision-making analysis given the earthquake activity and seismic hazard. We hope and believe that such a decision was made with a condition that the NPP 4 was constructed with a strict standard to compensate the high seismicity around the site. Under the circumstance, the location would be a logical option with the risk being minimized to an acceptable level, regardless of the construction cost.
