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.

Tritium instrumentation is required for the protection of personnel in any facility handling significant quantities of tritium. In such facilities, in a chronic or accidental tritium release situation, tritium may be present in the air as tritiated hydrogen gas (HT, DT, T2) or tritiated water vapour (HTO, T2O, DTO). For health protection purposes, the airborne tritium concentration of each species should be determined separately since the two species represent very different radiological hazards. This paper describes a tritium monitor that is capable of measuring the airborne concentration of tritium species in the range from 0.037 MBq/m3 (1 µCi/m3) to 7.4×104 MBq/m3 (2.0×106 µCi/m3) with a resolution of 0.074 MBq/m3 (2 µCi/m3) in the lowest range. The measurement principle is based on the separation of tritium species by a permeable membrane and the measurement of sample air activities by conventional ion chamber based tritium monitors.
