“The disappearance of a domestically owned capability would not only undermine U.S. leadership in a highly consequential arena of global commerce and security, it would render us dependent on foreign-controlled sources of uranium enrichment. This could increase the vulnerability not only of America’s commercial nuclear industry but of our national nuclear arsenal. Tritium, produced using enriched uranium, is necessary to maintain and modernize our nuclear weapons. Relying on foreign suppliers for material essential for maintaining the safety, security and reliability of our nuclear capability is unacceptable. It is critical that the federal government continue to invest in the research and development of technologies necessary to sustain modern and commercially viable domestic enrichment capability.”
