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.

A Iarge-aspect-ratio(LAR), midsize, diverted tokamak KT-2 with intense RF heating(5–7 MW) is under conceptual design process at KAERI. The machine parameters are: R/a(m) = 1.4/0.25 (reduceable to 0.20), Bt = 3 Tesla, Ip = 500+ kA, current flat-top 4.5 sec at maximum field and current (OH-only). The PF system concept design resulted in five KT-2 operation modes, and allows extended discharges for >30sec at 2T/200kA in the “5MW HiBS” mode. Construction will start in 1995, and the machine will start operation in 1998.
