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 Divertor Interferometer Diagnostics is located inside the 8th lower port plug of ITER and consists of 16 laser beam channels. The beam channels start from windows at the rear vacuum enclosure door of the port and pass through a shield block mounted on a structural sled. The cassette box of the laser beams is mounted on the central divertor cassette and the branching beams pass through the 20-mm gaps between the divertor cassette. Nuclear heating and damage (DPA and helium production) rats are calculated in structure of the divertor components and at the sensitive mirrors that direct the laser beams. Personnel dose rates are also calculated inside the port and at the inter space behind the port enclosure. The Distributed Memory Parallel (DMP) version of ATTILA code, SEVERIAN, is used in assessing the heating and damage rate while the dose rate analysis is performed using the serial ATTILA. A 40-degrees CAD model was constructed based on ALITE03 and ALITE04 MCNP CATIA model. About 1.88M cells were used with Sn32P3 approximation along with a 46n-21 cross section library based on FENDL2.1.
