Zaijing Sun (Health Physics and Diagnostic Sciences) published “Temporal Data Mining in Nuclear Site Monitoring and In-situ Decommissioning,” a chapter in the book “Nuclear Power Plant Design and Analysis Codes” this month with Elsevier. The author discussed the techniques of temporal data mining (TDM) and how to apply it to nuclear site monitoring and in-situ decommissioning (ISD). The study indicated that TDM techniques and corresponding codes are effective tools to validate ISD performance. The frequent episodes found in the data stream not only showed the daily cycle of the sensor responses but also established the response sequences of different types of sensors, which was verified by the actual experimental setup at the Savannah River Site.
