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.

Combination of liquid lithium with Reduced Activation Feritic/Martensitic Steel (RAFM) is one of the options for Test Blanket Module (TBM) in early ITER period and early DEMO blanket, as well as an intermediate step toward Li/V DEMO blanket. In this paper, characterization of a Li/RAFM blanket was carried out and compared with a Li/V blanket from neutronics and compatibility viewpoints.Although the local Tritium Breeding Ratio (TBR) will be reduced by ∼0.1 by the change from Li/V to Li/RAFM, Li/RAFM seems to be still feasible, with enhanced neutron shield, from the tritium self-sufficiency viewpoint. A similar tritium production rate for the Li/V and the Li/RAFM TBMs suggests that the Li/RAFM TBM simulates well the tritium production of Li/V TBM and thus will be suitable for Li/V DEMO blanket design as well as Li/RAFM blanket.Based on the available data, V-alloys are thought to be highly compatible with Li when the impurity level in the Li is low. New compatibility experiments of RAFM with Li showed transformation of martensitic to ferritic phase in addition to corrosion loss. However, the compatibility issue is estimated to be small for ITER-TBM conditions.The present study showed the significance of starting with a Li/RAFM TBM during the early phase of ITER operation for development of both Li/RAFM and Li/V DEMO blankets.
