Nathaniel Read, Ph.D.

Chief Safety Case Engineer

Dr. Read’s present work is concerned with detecting the early signs of nuclear power station decline, whether technical or organizational, that could lead to an accident. Following the Chernobyl accident, it was recognized that a single incident can have global consequences, leading to the establishment of the World Association of Nuclear Operators (WANO). This organization conducts periodic reviews of the global nuclear power station fleet and collects data on operational incidents, including those that are relatively minor. Dr Read’s current postdoctoral work seeks to apply modern machine learning techniques to this dataset to attempt to detect early signs of station decline that could lead to an accident. This vein of thinking emerged after the Three Mile Island incident, after which it became clear that focusing on seemingly small operational details can greatly reduce the probability of large accidents as well improving plant reliability and economics. His research continues in the same philosophy but with the modern advantages of large datasets and the tools to understand them.
