LM Visitors Centers Closed to the Public


Updated on 01/27/2021

During this unprecedented COVID-19 crisis, the health and safety of our employees and communities are our highest concerns. To ensure social distancing and comply with direction that nonessential activities be limited, the indoor areas of our centers will remain closed until further notice. 

The closed centers are the Fernald Preserve Visitors Center near Hamilton, Ohio; the Weldon Spring Site Interpretive Center in St. Charles, Missouri; the Atomic Legacy Cabin in Grand Junction, Colorado; and the Window Rock, Arizona, Community Outreach Network Office. Updates will be posted to the LM website.

In response to the Jan. 20, 2021, Executive Order on Protecting the Federal Workforce and Requiring Mask-Wearing, all visitors to our outdoor areas — including trails, gardens, and parking areas — are required to wear a mask when they’re 6 feet or closer to anyone not in their immediate group.

We will continue to update our communications, if anything changes in the status of our interpretive centers, and we look forward to the time when we can safely welcome our visitors back inside. In the meantime, we welcome you to enjoy the available outdoor spaces, trails, and online activities. Stay safe!

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.

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.
