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.

Recently, pre-ionization experiments using thermal electron emission from LaB6 cathode and electron heating by 2 kW@14.5 GHz Klystron installed at cusp and plug cell respectively have been carried out in Hanbit mirror device. Charge exchange collision between ion and neutral atom has been concerned as an important mechanism of ion energy loss in the Hanbit discharges, hence the high pressure of neutral particles is one of the most reasonable cause of low ion temperature. In this work, we investigate low pressure operation mode with help of the pre-ionization to enhance the ion temperature. The ion temperature and temperature anisotropy are measured and also inferred by ELA(End Loss Analyzer) for central cell plasma. We also characterize RF heating properties for different regimes of /c0i using simulation code for electromagnetic waves.
