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.

Cryogenic adsorption is effective for the separative recovery of hydrogen isotopes of small concentrations from the bulk helium gas. Thus, the cryogenic adsorption method is considered to be applied to the recovery of tritium from the blanket sweep gas which recovers tritium from ceramic breeder materials, the cleanup system of the helium discharge exhaust gas of the fusion reactor and so forth. The authors performed a screening test to find more suitable adsorbents for the recovery of hydrogen isotopes from the bulk helium gas at liquid nitrogen temperature. The authors tested various adsorbents, and the screening test indicates that a natural mordenite adsorbent has a quite high adsorption capacity for hydrogen under the helium atmosphere. For the adsorption of deuterium, it was found that the natural mordenite adsorbent have a high adsorption capacity even at lower pressure range of deuterium. The adsorption rate of hydrogen isotopes was quantified by analyzing breakthrough curves obtained in the experiments. Evaluated effective pore diffusivities of hydrogen isotopes in the mordenite adsorbents are comparable to that in MS5A adsorbents. Thus, it can be said that mordenite adsorbents are also suitable for adsorption of hydrogen isotopes from the viewpoint of adsorption rates. The results mentioned above suggest that the mordenite-type of adsorbents is promising for the recovery of low-concentration hydrogen isotopes from the helium bulk gas.
