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.

According to the recent low gas-puff experiments in Hanbit magnetic mirror device, the achievable ion temperature is limited largely by neutral content. For discharges with the low gas-puff with the pre-ionization technique, higher ion temperature is estimated compared to the high gas-puff case. Neutral transport and corresponding particle balance in this low gas-puff discharges in Hanbit are analyzed with the two dimensional Monte-Carlo simulation code coupled with a simple parallel plasma confinement formula. The radial ion temperature and power loss profiles are also derived. The global particle balance is between the plasma pumping and the recycling processes, hence the initially puffed amount of gas has negligible contribution to the total particle source.
