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.

High flux level reaction rates are measured from the gamma-ray emission analysis of activated foils. These foils are analyzed nondestruc-tively to eliminate error due to dissolution, dilution, and/or chemical separation. Signal-to-noise enhancement is achieved through the exclusive use of lithium-drifted germanium detectors, always with high peak-to-Compton ratios and occasionally with active Compton suppression. The reduction of the gamma-ray spectral data to accurate reaction rates as performed in three independent laboratories is categorized to illustrate the areas of potential pitfalls and the diversity of approaches used in successfully avoiding them. The estimated absolute errors and the range of results among the laboratories have been reduced below the target value of ±10% (2σ) for nonfission foils and is approaching the target value of ±5% (2σ) for fission foils.
