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 Systems Usability Case (SUC) approach enables a requirement-based human factors (HF) evaluation of complex technical systems that may cover the entire verification and validation process. SUC is based on the Safety Case approach and on the Systems Usability (SU) construct. One of the main aims of establishing a Safety Case is to bring the arguments and evidence for safety to the front in such a way that the reasoning supports the work of a regulator or licensing organization. In the end, the approach enables evaluating the SU of a system and making a reasonable solid argument about the acceptance of the system for use. The question is how the conclusions are reached through a reasoning process in which the arguments are made about the evidence [i.e., identified human engineering discrepancies (HEDs)] to approve or reject the claim concerning the quality of the system. The paper presents an application of SUC to real data from an integrated system validation of the modernized control room (CR) of the Loviisa nuclear power plant. The results of the validation are discussed from the point of view of how the SUC approach enables forming a statement about the acceptance of the CR. Moreover, practical examples are given to demonstrate the identified HF issues and how they were handled in the validation process. The paper provides a general framework for handling of HEDs and for their resolution that can be used in the consolidation of validation test results in a real-world validation project.
