Interpretive Centers Now Open

LM interpretive centers in Colorado, Missouri, Ohio now open

Two years ago, the U.S. Department of Energy (DOE) Office of Legacy Management (LM) closed its doors to all three of its interpretive centers because of the COVID-19 pandemic. LM staff quickly adjusted to the closure, offering a variety of virtual programming and events to the public, until federal guidelines for workers allowed opening the interpretive indoor spaces again.

Starting Friday, April 15, LM has reopened its interpretive centers. The Atomic Legacy Cabin in Grand Junction, Colorado; the Fernald Visitors Center near Hamilton, Ohio; and the new Weldon Spring Site Interpretive Center in St. Charles, Missouri, will again welcome visitors indoors. Each of the three centers are open during normal business hours. Staff at the three sites will continue to produce and host virtual programming for audiences. 

Protection of human health and the environment is always LM’s top priority. Visitors are encouraged to continue practicing COVID-19 protocols including social distancing and proper hygiene such as washing hands for at least 20 seconds, covering your mouth and nose when coughing and sneezing, and staying home when feeling ill. Face cover requirements follow the Centers for Disease Control and Prevention (CDC) county transmission levels. You can preview face cover requirements by searching either Hamilton County, Ohio; St. Charles, Missouri; or Mesa County, Colorado, in the CDC’s COVID-19 by County tool. 

Staff will continue to monitor guidance from the federal government, CDC, and state and local health departments. Adjustments to protocols may change with community conditions.

Members of the public are encouraged to celebrate, explore, and discover the various offerings across these three facilities.

Welcome back!


LM has several sites that are regularly open to visitors. It’s important to us that members of the public have access to the information they need to be confident about the safety of our sites. LM’s visitor and interpretive centers provide valuable information to communities about the history of sites, their cleanups, and our ongoing long-term stewardship work. 

LM also collaborates with other organizations at multiple public interpretive centers related to our sites and our mission.

Non-Federally Operated Centers

Dr. Modesto Iriarte Technology Museum, Rincón, Puerto Rico

The Dr. Modesto Iriarte Technology Museum is in the decommissioned Boiling Nuclear Superheater (BONUS) reactor, located northwest of Rincón, Puerto Rico. The reactor was developed as a prototype nuclear power plant using superheated steam. It was the eighth nuclear power plant constructed in the world, and first in Latin America. During operations from 1965 to 1968, 694 scientists and students from 41 foreign counties received training at the BONUS facility. Visitors to the museum can view the intact control room, learn about the history of the BONUS site, as well as the development of electric power and nuclear energy.

Mound, Ohio, Cold War Discovery Center

The Mound Cold War Discovery Center is a collaboration between the Mound Science and Energy Museum Association, a non-profit organization that was established to collect, preserve, and make publicly accessible the heritage of the Mound Laboratory and Dayton History, a private non-profit (501c3) organization established to preserve, share, and celebrate the history of the Dayton, Ohio, region. Visitors to the center can learn about the top-secret, scientific work of the Mound Laboratory that revolutionized Cold War, Nuclear Age, and Space Race history; the subsequent environmental cleanup; and today’s ongoing legacy management.

Manhattan Project National Historical Park

The Manhattan Project National Historical Park (MAPR) is managed through a collaborative partnership by the U.S. National Park Service (NPS) and the U.S. Department of Energy (DOE) to preserve, interpret, and facilitate access to key historical resources associated with the Manhattan Project.
