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.

The potential value of probabilistic risk assessment (PRA) tools to fusion safety and economic issues is discussed. The main results and implications of a systematic examination of these general issues via PRA tools are reported. It is concluded that PRA methodology, tools, and thinking are useful to fusion research in the process of further improving fusion concepts and ideas. The MARS and STARFIRE designs are examined for possible answers to questions posed by using PRA tools. Several general magnetic-fusion design insights result from the study, including the following: 1. possible fault interactions must be minimized by decoupling fault conditions 2. the reliability of the vacuum boundary appears vital to maximizing facility availability and minimizing safety risk 3. economic analyses appear to be incomplete without consideration of potential availability loss from forced outages. A modification to PRA formalism called the “fault interaction matrix” is introduced. The fault interaction matrix contains information concerning what initial fault condition could lead to another fault condition, with what frequency. Thus, the fault interaction matrix represents a way to present and measure the degree to which a designer has decoupled possible fault conditions in his design. Such decoupling is crucial to enhancing fusion safety and facility availability.
