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.

Silicon Carbide (SiC) has been proposed as a possible candidate material for flow channel inserts for the dual coolant blanket concept. Here, the total electrical resistance of disks of high purity CVD SiC were measured with liquid lead-lithium eutectic (LLE) alloy melts serving as electrodes. From this data, the relative contributions of intrinsic resistivity and surface contact resistance as a function of measurement temperature was deduced. It was shown that after a relatively short period of exposure, once wetting at the interface was achieved, that contact resistance at the SiC/LLE interface was not significant. The contact resistance during initial exposure did not behave in a repeatable consistent way and appears to be affected by small variations in sample preparation. For modeling purposes, the electrical properties of an FCI can be based on the intrinsic electrical conductivity of the material and the dimensions. However, longer term operations and effects of impurities still need to be addressed.
