DOE schedules 2026 demolition, cleanup of Los Alamos Ion Beam Facility

The U.S. Department of Energy has scheduled physical demolition of the 60,000-square-foot Ion Beam Facility at Los Alamos National Laboratory to begin in 2026, with the administrative wing and the horizontal accelerator slated for removal in the first half of the year. The facility, built in 1951 and home to two Van de Graaff accelerators, has been deactivated because of contamination, and the project timing and site cleanup sequencing were presented to the Northern New Mexico Citizens Advisory Board.

DOE Los Alamos Field Office leadership framed the work as the transition from deactivation to physical removal. Aptim Federal Services has managed deactivation tasks to date, preparing the building for demolition and the next steps in remediation. The shift to demolition marks a visible phase in addressing a Cold War-era structure that has remained on the LANL footprint for decades.

Local implications are practical and procedural. Demolition and cleanup will generate decisions about classification, handling and disposal of contaminated materials, and where waste will ultimately be shipped. Those decisions will influence truck traffic, scheduling of work near populated areas, and the scale and duration of radiological and environmental monitoring that residents and local governments will expect. For county officials and neighbors, the immediate concern is transparency about sequencing, protective measures for workers and the public, and timely reporting of monitoring results.

Institutionally, the work falls under DOE project management with contractor execution. The Northern New Mexico Citizens Advisory Board served as the forum for DOE to describe timing, underscoring the role of community oversight in tracking progress and raising questions about scope, cost and safeguards. Aptim Federal Services’ role in deactivation positions the contractor for continuity into demolition activities, but the transition will require clear lines of regulatory compliance and public reporting.

Policy implications extend beyond demolition logistics. Funding allocations, federal cleanup priorities and decisions about long-term disposition of contaminated materials will shape both the pace of work and community confidence. Local elected officials and oversight bodies will have leverage through public meetings and advisory channels to press for detailed schedules, independent monitoring data and contingency plans for potential disruptions.

For Los Alamos County residents, the start of physical removal in 2026 is a milestone in addressing a legacy source of contamination and an operational change at the Lab. Expect announcements from DOE Los Alamos Field Office and the Northern New Mexico Citizens Advisory Board about sequencing and monitoring details in coming weeks, and continue to follow advisory board briefings to assess how cleanup choices will affect health, traffic and long-term land use in and around the Lab.
