Delivering new nuclear on time, the first time
Mark Rinehart
The nuclear industry is entering a period of renewed urgency, driven by the need for stable baseload power, heightened energy security concerns, and expanded defense infrastructure. Now more than ever, we must deliver new nuclear projects on time and on budget to maintain public trust and industry momentum.
The importance of execution certainty cannot be overstated—public trust, industry investment, and future deployment all hinge on our ability to deliver these projects successfully. However, history has shown that cost overruns and schedule delays have eroded confidence in the industry’s ability to deliver nuclear construction. As we embark on many first-of-a-kind (FOAK) reactor builds, fuel cycle infrastructure projects, and extensive defense-related nuclear projects, we must ensure that execution certainty is no longer an aspiration—it is an expectation.

Development of Water Cooled Solid Breeder (WCSB) TBM, the primary candidate of ITER Test Blanket Module (TBM), has been performed in Japan, according to the TBM milestones, which are necessary for acceptance of the TBM in ITER for testing from the first day of plasma operation. The TBM milestones consist of milestones on safety assessment, module qualification and design integration in ITER. For the safety milestones, essential source terms were evaluated, and failure modes and effect analysis (FMEA) was performed. Based on the results of FMEA, safety assessment was performed. For the milestones of the design integration, detailed structural design of the TBM and the interface structure with the ITER test port were performed. Based on the design, performance analysis such as thermo-mechanical analysis in over-pressurization was performed. For the milestones of the qualification of fabrication technology, essential fabrication technology was developed and near full size first wall of the TBM was successfully fabricated and demonstration of the integrity in heat flux equivalent to ITER. The development of the WCSB TBM is showing steady progress toward the installation in ITER.
