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.

Session Chair:
Eva E. Davidson
Session Organizer:
With increased high-performance computing (HPC) capabilities, multiphysics codes for reactor applications can be powerful in simulating complex reactor behavior for advanced reactors and the current fleet of light water reactors. There are many advantages to simulating reactor behavior with multiphysics codes, and they can aid in the design and licensing of reactor concepts. However, there are challenges to coupling codes simulating various physical phenomena including working with different time scales, meshes, units etc. which will be discussed. In addition, the panel discussions will include additional issues such as verification and validation of multiphysics codes and software usability by analysts who are not subject matter experts in all physical phenomena being simulated.
