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.

Data for the dryout heat fluxes in deep beds of volumetrically heated particles are obtained when the overlying liquid is subcooled or a certain prescribed cooling condition is applied at the bottom of the particulate bed. Semitheoretical correlations proposed earlier for saturated boiling in the particulate beds with insulated bottom have been extended to correlate the data with cooling at the bottom. Visual observation of the particulate bed after dryout indicates that initial size and growth of the dryout patch significantly depends on the magnitude of the heat generation rate at the time of dryout.
