Shifting the paradigm of supply chain
Chad Wolf
When I began my nuclear career, I was coached up in the nuclear energy culture of the day to “run silent, run deep,” a mindset rooted in the U.S. Navy’s submarine philosophy. That was the norm—until Fukushima.
The nuclear renaissance that many had envisioned hit a wall. The focus shifted from expansion to survival. Many utility communications efforts pivoted from silence to broadcast, showcasing nuclear energy’s elegance and reliability. Nevertheless, despite being clean baseload 24/7 power that delivered a 90 percent capacity factor or higher, nuclear energy was painted as risky and expensive (alongside energy policies and incentives that favored renewables).
Economics became a driving force threatening to shutter nuclear power. The Delivering the Nuclear Promise initiative launched in 2015 challenged the industry to sustain high performance yet cut costs by up to 30 percent.

Data analytics should be at the center of strategic maintenance decision making. The diversity and quality of data collected provides key intuition that drives effective decisions on complicated topics. Online condition monitoring is used to reduce time based preventive maintenance and to enable predictive maintenance. Effective interpretation of data leads to information that plant operators can turn into decisions and actions that improve operations and maintenance activities. Data analytics is the primary technique used to facilitate effective data interpretation that will generate revolutionary results. The starting point is the data. Patterns in the data are noted and observed. The patterns observed while the plant is operating under preset conditions define process states. These patterns are mathematically manipulated to highlight changes when process changes are detected. The methods that detect state changes usually rely on correlation algorithms. Statistics are used to determine if the changes in the patterns are real or caused by plant noise and uncertainty levels. Integrated tools are used to implement algorithms that form the data analytics process and automate the decision making. Operations research is necessary to understand the operational context of the data. Machine learning algorithms provide dynamic mathematical means that can understand the present state and predict the next state with a degree of certainty. It is this prediction and the associated prediction certainty that allows plant operators to make effective decisions. This paper will discuss the approach to build a roadmap that will migrate data analytic techniques into production facilities.
