An open letter to Chris Wright
Craig Piercycpiercy@ans.org
Dear Secretary Wright:
On behalf of the U.S. nuclear professional community, I offer our sincere congratulations to you on your becoming the secretary of energy.
By now, I’m sure you have figured out that “Department of Energy” is a misnomer. If the Department of Government Efficiency ever requires truth in advertising, the DOE should be renamed the “Department of Nuclear Weapons, Security, Cleanup, and Sundry Energy and Science Programs.” That’s because more than 60 percent of the DOE’s budget is dedicated to “atomic energy defense activities”—making sure our nuclear bombs work, our aircraft carriers and submarines sail, and our Cold War messes get cleaned up.
