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.

Solubility measurements of tritium (T) in Pd1−YAgY alloys (Y = 0.00, 0.10, 0.20, 0.30) are reported in the temperature range of 250 K to 733 K, the pressure range below 3 bar, and the concentration range of 0.001 to 0.64 hydrogen to metal atom ratio. To study isotopic effects, the pressure-concentration-temperature relationships of the hydrogen isotopes protium (H) and deuterium (D) have been measured using the same samples and experimental setup and to temperatures as high as 1500 K using a different set up and samples. The experimental data are compared with values for H and D determined by other groups. In the case of T, most of the data presented have not been determined before. From these data the Sieverts' constants were calculated which show a strong temperature and isotope dependence. Analytical expressions, based on models that assume various degrees to which the hydrogen can perceive the alloy composition of individual sites in an alloy, are given for the Sieverts' constants that allow the calculation of the standard Gibbs free energies, enthalpies and entropies of H, D, and T in these alloys.
