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.

The capabilities of new methods of fusion alpha-particle diagnostics based on nuclear reactions are discussed. Particularly, the resonant capture reactions between confined fast alpha particles and low-Z artificial impurities in the plasma is examined. In this case, the intensity of the decay gamma rays is proportional to the alpha-particle concentration at resonance energy. Another method is based on Doppler shape analysis of the 4.44-MeV gamma-ray spectra from the 9Be(α, n1γ)12C reaction. Results of an in-beam study of this diagnostic reaction are given. Some questions concerning the gamma spectrometer, a collimator, and a radiation shield are discussed. Estimates of the reaction rates and signal values in the Tokamak Fusion Test Reactor, T-14, Compact Ignition Tokamak (CIT), and International Thermonuclear Experimental Reactor (ITER) are presented. In conclusion, the use of gamma spectroscopy in the diagnostics fusion protons in deuterium-deuterium plasma is examined.
