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.

Experiments in a large zero-power graphite reactor indicate that simple-point reactor kinetics adequately describe the neutron fluctuation spectra everywhere except near the edges of the reactor. Near the edges, the break frequencies and rolloff slopes differ significantly, and anomalous irregularities in the distribution are observed. Computations explicitly for the large reactor, based on recently proposed theories, also agree excellently away from the edges, and fail to predict the measured spectra near the boundary.
