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.

The purpose of the High Flux Test Module (HFTM) in International Fusion Material Irradiation Facility (IFMIF) is to irradiate material specimens to a very high fluence (DEMO relevant ones) in a very few years. In IFMIF-EVEDA which is selected as one of the broader approach activities, the reference solution for the assemblies is a vertical set-up (EU); an alternative horizontal solution, H-HFTM (Japan), which could become very useful for very high temperature tests, is also part of this work. This paper presents the overview of H-HFTM and reports on the recent Japan activities for H-HFTM in the IFMIF-EVEDA framework.
