Domestic reactor in Texas moves toward US-made medical isotopes

A newly constructed low-power reactor outside Lockhart, Texas, became critical in August, marking a milestone toward domestic production of medical radioisotopes. Although the plant will not supply power to the Texas grid, its primary purpose is to create short-lived isotopes used in cancer imaging and other medical procedures. Currently, the United States imports the majority of these materials, leaving patients vulnerable to supply chain interruptions and geopolitical pressures that can shorten the usable window of the isotopes.

By locating production closer to hospitals and research facilities, the reactor could ensure more reliable access and reduce treatment delays. The development highlights growing concerns over dependence on foreign sources for critical healthcare supplies. If successful, the project may serve as a model for similar facilities serving other sectors that require radioactive materials.
