UCOR crews are using a hybrid excavator to support demolition of the Old Steam Plant, Building 9401-1, at Y-12, resulting in cost savings and more efficient operations.
The equipment uses an electric swing motor that regenerates energy as the excavator rotates, reducing engine demand and fuel consumption by approximately 20%. Its quieter operation improves communication around the equipment, enabling safer cleanup operations.
The technology helps crews efficiently remove the 13,454-square-foot Old Steam Plant, constructed in 1943. Over its more than 80-year life-span, the facility supported uranium operations, fuels testing, maintenance, and storage. Crews completed major deactivation in 2021, removing hazards and isolating utilities to prepare the building for demolition.
Demolition began this summer, a full year ahead of schedule, reducing risks and long-term surveillance and maintenance costs while responsibly managing taxpayer dollars. UCOR is targeting completion of the Old Steam Plant demolition by December.
Beyond this project, the hybrid excavator could provide lasting benefits. With an estimated 20% reduction in fuel use and more efficient debris handling, deploying the equipment across the Oak Ridge Reservation could reduce carbon footprint and create cost savings per demolition project while supporting UCOR’s focus on safety, sustainability, and continuous improvement. On the Old Steam Plant alone, the hybrid excavator will save $2,500. Once larger cleanup campaigns deploy, these cost-savings will be significant.
