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 real advantage of the laser driver as compared to other drivers is its ability to provide a high quality focal spot on target. Heat generation in solid-state media has always been recognized as a limiting feature because at high repetition rate, the quality of this focal spot depends on the beam wave-front distortions. It is not easy to design the driver baseline because there are too many different parameters to deal with. In this paper, we introduce two figures of merit that show that Yb doped ceramics (either garnets or sesquioxides) are promising laser materials opening new fields during the research phase to demonstrate ignition and fusion gain (including the fast ignitor concept). When driven at low temperature (cryogenic cooling), all of the operational features of the laser amplifier can be demonstrated at an aperture scale of only 10-15 cm.
