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 main three subsystems of the ITER Tritium Fuel Processing Plant, the Tokamak Exhaust Processing (TEP) System, the Isotope Separation System (ISS) and the Storage and Delivery System (SDS), are equipped with enough instrumentation to control the various processes. In addition to this system-dedicated instrumentation, a central facility called Analytical System (ANS) has been designed for i) verification and determination of the composition of the various gas mixtures processed in the Tritium Fuel Processing Plant and ii) checking and monitoring the local equipment. The analytical requirements of the subsystems of the ITER tritium plant are summarised. A comparison of various analytical techniques revealed that gas chromatography is the most suitable method. The design of the Analytical System comprising three micro and two conventional gas chromatographs and its safe operation are discussed in detail.
