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.

An approximation to the transport equation is presented, which is capable of arbitrary accuracy and yields the exact transport-theory asymptotic behavior in all orders for any geometry. Anisotropic scattering is treated explicitly, and the inclusion of energy and time dependences is straightforward. The approximation, which is very similar to the usual spherical-harmonic (PN) method, is derived by introducing a new truncation scheme into the infinite set spherical-harmonic equations. This truncation method consists of assuming that the higher spherical-harmonic components, equated to zero in the PN method, can be related to lower components by assuming the angular distribution to be in an asymptotic distribution. The resulting approximation is very similar in structure to the PN approximation (in particular, it is no more complex) but has the added advantage of yielding exact asymptotic behavior.
