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.

Effects of anisotropic turbulence, which can develop in the flow of liquid metal in a transverse magnetic field, on the heat transfer-rate and on self-cooled blanket design and performance are investigated using recent experimental evidence and an approximate analytical model. It is found that the anisotropic turbulence might enhance the heat transfer rate by an order of magnitude without affecting the magnetohydrodynamics pressure drop. The enhanced heat transfer rate opens new interesting possibilities for the design of self-cooled liquid metal blankets, including the possibility of:(l)designing simple yet efficient poloidal-flow blankets, (2) reducing the pressure drop, and (3)increasing the exit coolant temperature and, hence, thermal-to-electrical energy conversion efficiency of conventional blanket concepts. A thorough investigation of the anisotropic turbulent flow phenomena is essential for enabling a realistic assessment of their implications. This investigation ought to include large-scale experiments that enable simulation of realistic fusion reactor conditions.
