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.

One of the tasks of the Tritium Laboratory Karlsruhe (TLK) is the development of a fuel clean-up system for future fusion reactors. The current reference process for the Tokamak Exhaust Process (TEP) system of ITER is called CAPER and consists of three different steps; the third step is based on counter current isotopic swamping to recover trace amounts of tritium in the so called PERMCAT. For testing the efficiency of the PERMCAT tritium concentrations below 3.7*1010 Bqm-3 need to be measured in a process gas, challenging real time measurement, a wide measurement range of at least 4 orders of magnitude and low memory effects. The sampling technique used at TLK to measure the tritium concentration at the outlet of the PERMCAT is discussed in details with regards to memory effects.
