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.

Neutron albedo methods can be used to simplify transport calculations in a wide variety of applications. Their utilization requires a collection of albedo data and a model which makes these results convenient for hand or machine computation. Results are presented here from neutron albedo calculations for incident intermediate-energy neutrons. These results can be explained using our knowledge of neutron interaction physics. Total albedos are directly related to the cross sections for elastic scatter and absorption. Angular distributions of reflected neutrons are approximately cosθr for all incident neutron conditions. The total albedo results are well modeled by an extension of a previously developed fast-neutron albedo model when ∑abs/∑t (the ratio of absorption to total cross section) is small.
