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.

In a fusion reactor of high safety and acceptability, safe confinement of tritium is one of key issues for the fusion reactor. Tritium should be well-controlled and not excessively released to the environment and to prevent workers from excess exposure. Especially, the hot cell and tritium facilities of ITER will use various construction materials such as the organic materials. The hot cell is maintained in the dry atmosphere very much, and the maintenance of the apparatus contaminated by high concentration tritium is assumed. Therefore, the hot cell may be contaminated by high concentration tritium. Since the epoxy paint which will be used as a paint on the wall of the hot cell was contaminated by tritium compared with metal material, it is very important to study the efficient decontamination of the epoxy paint from a viewpoint of the protection the excess exposure of the workers. For tritium decontamination processes, so-called 'soaking' effect is important. This effect is based on sorption of tritiated water vapor on the materials and subsequent desorption from them. Therefore, in order to develop for the optimal decontamination technique, the decontamination experiment was carried out as a function of water vapor concentration in the purge gas (N2) for epoxy paint, acrylic resin and butyl rubber. As the result, the desorption rate for the organic materials was evaluated by purging gas of N2, and then furthermore, the residual tritium on the organic materials was quickly removed by adding water vapor in purging gas. The effect of adding water vapor was found on the decontamination for the organic materials.
