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.

Ceramic electrolysis method that had been developed for tokamak exhaust processing can be applied for the process of highly tritiated water. Aiming to enhance the efficiency of ceramic electrolysis method, we developed new electrodes using cerium oxide (Ceria). We prepared electrodes by two manufacturing methods. One is to mix ceria into Pt paste and then electrode was sintering on the Yttria stabilized Zirconia (YSZ). The other is to use Ceria as intermediate layer between YSZ and Pt-YSZ electrode. In addition to this, different ceria concentrations of electrodes, 10%, 20% and 30%, were prepared for Ceria adding electrode. The water decomposition performance of such electrodes and usual electrode using Pt-YSZ was confirmed in different humidity at 1073K. Both electrodes using Ceria showed higher water decomposition performance than that of usual electrode. Especially, 30% ceria adding electrode showed highest performance and the decomposition efficiency was one order magnitude higher than that of usual electrode.
