能源部：Oak Ridge 2026财年清理取得进展 处理逾5,000万磅拆除废料
美国能源部（DOE）10月20日发布，能源部 Oak Ridge 环境管理办公室（OREM）与清理承包商 United Cleanup Oak Ridge（UCOR）表示，在截至9月30日的2026财年里，位于田纳西州 Oak Ridge 的清理工作取得多项里程碑进展，全年累计超过130万个安全工时。
据能源部发布，清理队伍在 Oak Ridge 保留区内处理曼哈顿计划与冷战时期遗留基础设施停用与拆除所产生的废料，全年经手超过5,000万磅废料，涉及 Y-12 国家安全综合体、Oak Ridge 国家实验室（ORNL）与 East Tennessee Technology Park（ETTP）三处地点。
其中，Y-12 一处累计超过30万个安全工时、移除超过4,300万磅废料，完成该地点迄今规模最大的拆除工程 Alpha-2 设施，以及 Old Steam Plant 的拆除；这座老蒸汽厂建于1943年、面积13,454平方英尺。在 Alpha-4 与 Beta-4 采用的新切割与隔离技术降低了作业风险，并节省超过2,000万美元。ORNL 方面，队伍累计375,581个安全工时，在 Isotope Row 推进10座设施的拆除，远程系统在6座老化设施中显著减少了工人辐射暴露。
土地修复方面，ETTP 的队伍累计超过91,810个安全工时、产生超过500万磅废料，工作包括排水修复、排放口管理、多余设备移除与曼哈顿计划历史文物保存；在曾用作冷战受污染设备与碎屑处置场、面积100英亩的 White Wing Scrap Yard，工人通过专门的植被管理计划清理了超过39英亩土地。废料作业队伍累计超过117,000个安全工时，管理超过1,100万加仑来自填埋场的废水；超铀废料处理中心对接触式与远程处理碎屑废料完成超过97%的表征、准备与处理。
OREM 副主管 Teresa Robbins 表示，Oak Ridge 各处的进展说明安全与任务执行可以相互促进，从移除遗留设施、管理数百万磅废料到为土地的下一用途做准备，这些成果在降低风险的同时，也支持 Y-12 与 ORNL 的长期任务。UCOR 执行副总裁兼副项目主管 Sean Dunagan 表示，公司正在加速清理、承担日益复杂的工作，同时始终把人员放在中心。
DOE: Oak Ridge Cleanup Advances in Fiscal 2026, With More Than 50 Million Pounds of Demolition Waste Managed
The U.S. Department of Energy (DOE) reported on October 20 that its Oak Ridge Office of Environmental Management (OREM) and cleanup contractor United Cleanup Oak Ridge (UCOR) achieved major cleanup milestones in fiscal year 2026, which ended September 30, logging more than 1.3 million safe hours at Oak Ridge, Tennessee.
According to the department, crews managed more than 50 million pounds of waste generated during the deactivation and demolition of legacy Manhattan Project and Cold War-era infrastructure across the Oak Ridge Reservation, at the Y-12 National Security Complex, Oak Ridge National Laboratory (ORNL) and the East Tennessee Technology Park (ETTP).
At Y-12, crews tallied more than 300,000 safe hours and removed over 43 million pounds of waste, completing the demolition of the Alpha-2 facility, the site's largest teardown to date, and of the Old Steam Plant, a 13,454-square-foot facility built in 1943. New cutting and isolation technologies used at Alpha-4 and Beta-4 reduced risk and saved more than $20 million. At ORNL, teams completed 375,581 safe hours, advanced demolition on 10 facilities on Isotope Row, and used remote systems that significantly reduced worker radiation exposure across six aging facilities.
At ETTP, crews recorded more than 91,810 safe hours and generated more than 5 million pounds of waste, with work including drainage restoration, outfall management, excess equipment removal and preservation of historic Manhattan Project artifacts. At the White Wing Scrap Yard, a 100-acre former disposal site for contaminated Cold War equipment and debris, workers cleared over 39 acres of land through a specialized Vegetation Management Program. Waste Operations crews recorded more than 117,000 safe hours, managed over 11 million gallons of wastewater from landfills, and the Transuranic Waste Processing Center characterized, prepared and processed more than 97 percent of contact- and remote-handled debris waste.
“The progress across Oak Ridge demonstrates what is possible when safety and mission execution reinforce one another,” OREM Deputy Manager Teresa Robbins said, adding that the work is reducing risk while enabling enduring missions at Y-12 and ORNL. UCOR Executive Vice President and Deputy Program Director Sean Dunagan said the company is accelerating cleanup and taking on increasingly complex work while keeping its people at the center.
