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.

Requirements for Attendees: General knowledge of MCNP6
Summary Paragraph: This tutorial focuses on using MCNP6.3 to perform criticality calculations for criticality safety and reactor physics applications and promoting use of MCNP version 6.3 at DOE sites. Lectures provide an overview of Monte Carlo simulation methods and highlight state-of-the-art in criticality simulations, eigenvalue calculations, convergence analysis and bias in k-effective. New features and physics improvements in MCNP6.3 will be covered including adaptive meshing, fission-matrix, accelerated fission convergence of neutron distribution, and new statistical tests for convergence. Sensitivity and uncertainty analysis using Whisper-1.1 will be discussed and calculation examples demonstrated.
