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.

Several methods of decontamination, such as melting, heating with flame, isotopic exchange with gaseous hydrogen, replacement with hydrogen, and thermal desorption under moist gas, were tested on stainless steel, INCONEL®, beryllium, copper, and aluminum bronze contaminated with tritium. The detritiation methods were assessed with respect to the fraction of the tritium inventory removed, the residual tritium concentration remaining, and the reduction in the rate of tritium outgassing. Potential applications of these decontamination methods include detritiation of the Joint European Torus (JET) vacuum vessel and the tritium plant prior to dismantling for decommissioning and subsequent processing of the intermediate-level waste this has generated.
