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 equations and boundary conditions that constitute the P1 approximation to the space-time-energy transport equation and its adjoint can be obtained from a variational expression that admits trial functions discontinuous in space and energy. This expression can then be used to derive all the standard forms of the few-group diffusion equations—equations using flux averaged constants, over-lapping group equations, parallel group equations—as well as many more hitherto unexamined. Such a procedure is carried out in the present paper. All the standard few-group results, as well as formally exact few-group equations and multigroup equations, are shown to be special cases of a single general form derived from the variational expression. Internal boundary conditions are obtained automatically, and it is shown that in some cases discontinuities in fluxes and currents ought to be imposed across internal boundaries.
