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.

As a part of design study of candidate DEMO blanket in Japan, evaluations of tritium permeation in solid breeder blankets cooled by supercritical water was performed. The evaluations were performed under detail design of the blankets with nuclear and thermal analyses. F82H was selected as the structural material and the temperature of cooling tubes in the tritium breeder zone was evaluated between 673K and 783K. In this temperature range, tritium permeation rate through the cooling tubes in tritium breeder zone was evaluated and also tritium permeation into the first wall cooling water by the implantation of tritium particle was evaluated. In addition, requirements for preventing tritium permeation into the cooling water have been examined.
