From operator to entrepreneur: David Garcia applies outage management lessons
David Garcia
If ComEd’s Zion plant in northern Illinois hadn’t closed in 1998, David Garcia might still be there, where he got his start in nuclear power as an operator at age 24.
But in his ninth year working there, Zion closed, and Garcia moved on to a series of new roles—including at Wisconsin’s Point Beach plant, the corporate offices of Minnesota’s Xcel Energy, and on the supplier side at PaR Nuclear—into an on-the-job education that he augmented with degrees in business and divinity that he sought later in life.
Garcia started his own company—Waymaker Resource Group—in 2014. Recently, Waymaker has been supporting Holtec’s restart project at the Palisades plant with staffing and analysis. Palisades sits almost exactly due east of the fully decommissioned Zion site on the other side of Lake Michigan and is poised to operate again after what amounts to an extended outage of more than three years. Holtec also plans to build more reactors at the same site.
For Garcia, the takeaway is clear: “This industry is not going away. Nuclear power and the adjacent industries that support nuclear power—and clean energy, period—are going to be needed for decades upon decades.”
In July, Garcia talked with Nuclear News staff writer Susan Gallier about his career and what he has learned about running successful outages and other projects.

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.
