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.

Heat transfer performance for high Prandtl number and high temperature molten salt flow in a circular pipe and in sphere-packed pipes are evaluated with modified Tohoku-NIFS Thermofluid Loop (TNT loop) using high-temperature molten salt HTS (KNO3 : NaNO2 : NaNO3 = 53 : 40 : 7), as a stimulant of Flibe (LiF : BeF2 = 66 : 34). The modified TNT loop has much longer entrance region to develop a thermal boundary layer, which enable us to obtain more precise heat transfer data.In the modified TNT loop experiments, the heat transfer characteristics in a circular pipe flow have good agreements with the representative correlations. It is obvious that the analogy for heat and momentum transfer is also valid for high-temperature and high-Prandtl-number molten salt flow. It is also confirmed that the heat transfer performance of sphere-packed pipes increases up to about 4 times higher than that of circular pipe, in case of relatively low flow rate. This can be effective in the Flibe blanket system from the viewpoints of moderating MHD effect and electrolysis.
