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 semi-implicit method for solving the full compressible resistive magnetohydrodynamic equations in three dimensions is presented. The method is designed for use in the modeling of fusion plasmas in magnetic confinement devices. The method is unconditionally stable with respect to the fast compressional modes. The time step is limited instead by the slower shear Alfvén motion. The computing time required for one time step is essentially the same as that for explicit methods. The code is applied to resistive instabilities in cylindrical tokamak equilibria.
