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 set of thermodynamic properties of high-temperature, weakly nonideal Flinabe (LiF-NaF-BeF2) gas is calculated and presented. High-temperature Flinabe gases (plasmas) appear in the inertial fusion energy chamber over a wide range of temperatures and pressures due to the absorption of X-rays and debris, emitted from the target microexplosion, within a very thin surface layer of the Flinabe liquid wall. The equation-of-state (EOS) and ionization equilibrium data of the resulting high-temperature gas were computed and are presented in another paper. In this paper, the set of thermodynamic properties (specific enthalpy, specific heats, adiabatic exponent, and sound speed) that are required, in conjunction with the Flinabe EOS, to perform gas dynamics calculations and the required assessments of many research and development issues in nuclear fusion is modeled and computed consistently with the previously presented EOS and ionization equilibrium data. This set of Flinabe thermodynamic properties is missed in the literature, and the need to model and estimate these properties seems to be immediate rather than justifiable. Computational results for Flinabe thermodynamic properties are presented and discussed. These properties have been presented as a set of isobars that have been validated by obtaining the limiting conditions at very high temperatures for a fully dissociated/fully ionized gas.
