APTIM-AMENTUM ALASKA DECOMMISSIONING LLC

APTIM-AMENTUM ALASKA DECOMMISSIONING LLC specializes in the safe, regulatory-compliant decommissioning and dismantlement of legacy nuclear and defense facilities, with demonstrated expertise in radiological remediation, nuclear facility deactivation, and hazardous material management. The contractor’s core capabilities center on the end-of-life closure of complex military infrastructure, including reactor systems, containment structures, and associated utilities, adhering to DOE, NRC, and DOD environmental standards. Their technical proficiency includes radiological characterization, decontamination and decommissioning (D&D) planning, waste packaging and transport, and site restoration to meet unrestricted use criteria. Specialization in Arctic and remote-site operations enables execution in extreme environmental conditions, with rigorous protocols for worker safety, contamination control, and environmental monitoring. The contractor has delivered services exclusively to the Department of Defense, specifically supporting the decommissioning of nuclear-powered infrastructure at military installations. Their work involves complex coordination with military engineering, environmental compliance, and nuclear safety teams to ensure mission continuity during facility closure. Their primary industry focus is remediation services under NAICS 562910, which in practice means managing the full lifecycle of nuclear and radiological facility closure—from planning and characterization to dismantlement, waste disposal, and final site certification. This positions them as a niche provider in the defense nuclear infrastructure retirement market, serving high-consequence, low-volume projects requiring specialized regulatory and technical knowledge. As a 2L entity headquartered in Baton Rouge, Louisiana, the company operates as a specialized subsidiary focused on mission-critical federal decommissioning tasks. While no federal certifications are currently listed, their operational model reflects deep compliance with federal environmental and nuclear safety regulations. Their geographic presence is defined by project location rather than permanent offices, with active engagement in remote Alaskan defense sites, reinforcing their capacity to execute high-risk, logistically complex federal missions in austere environments.
