Decommissioning of Irradiators

ATOM SPEC specializes in the safe removal and decommissioning of Category I self-contained irradiators and Category II gamma beam irradiators, as well as medical Gamma Knife units. As a licensed provider, we are authorized to perform device removals and support complex projects involving sealed radioactive sources.

We actively assist the Los Alamos National Laboratory Off-Site Source Recovery Program (OSRP), ensuring that disused and excess radioactive materials are recovered, secured, and properly dispositioned.

Our turnkey approach covers every phase—from radiological surveys and regulatory coordination to packaging, transportation, and final disposition—delivering a safe, compliant, and streamlined process for your facility.

Safe, Compliant, and Efficient Decommissioning Solutions

ATOM SPEC provides comprehensive decommissioning services for facilities, equipment, and radiological assets that have reached the end of their operational life. Our team combines structured planning, disciplined execution, and rigorous project closeout to ensure full compliance with regulatory and safety requirements.

We support decommissioning across nuclear, industrial, research, and medical environments, delivering defensible, audit-ready outcomes while minimizing risk and operational disruption. Our scope includes the removal of Category I self-contained irradiators, Category II gamma beam irradiators, and medical Gamma Knife units, performed under appropriate licensing and regulatory authorization.

ATOM SPEC also supports the Los Alamos National Laboratory Off-Site Source Recovery Program (OSRP), facilitating the safe recovery and disposition of disused sealed radioactive sources.

Our work aligns with applicable regulatory frameworks, including U.S. Nuclear Regulatory Commission requirements (10 CFR), Agreement State programs, and international standards such as International Atomic Energy Agency guidance, as applicable to each project.

Decommissioning Capabilities

Planning & Regulatory Support

We establish a clear, compliant path forward before field work begins — reducing uncertainty and aligning all stakeholders early in the process.

  • Feasibility studies and scope definition

  • Development of tailored Decommissioning Plans (DPs)

  • Licensing support and regulatory submissions

  • Coordination with regulators and project stakeholders

Site Characterization & Risk Assessment

A defensible technical baseline is critical. We perform detailed characterization to inform strategy, safety controls, and project execution.

  • Radiological and chemical hazard surveys

  • Environmental and occupational safety assessments

  • Data-driven risk evaluation to define scope and controls

Decontamination & Dismantlement

Execution is performed using controlled, industry-aligned methods that prioritize safety, containment, and efficiency.

  • Decontamination of facilities and equipment

  • Dismantling and segmentation of structures

  • Handling of regulated and hazardous materials

Waste Management & Disposal

We manage waste streams from generation through final disposition, ensuring full traceability and compliance.

  • Packaging and transport of contaminated materials

  • Coordination with licensed disposal facilities

  • Waste tracking, manifests, and documentation

Final Status Surveys & Reporting

We close the loop with clear, defensible documentation that supports regulatory release and long-term confidence.

  • Final status surveys to demonstrate cleanup criteria

  • Regulatory closeout documentation

  • Support for license termination or conditional release

Industries We Serve

  • Nuclear power plants and research reactors

  • Industrial facilities with radiological assets

  • Medical and research laboratories

  • Government and defense facilities

  • University and academic sites

International Project Support

ATOM SPEC supports decommissioning and radiological projects outside the United States through a structured, compliance-focused approach tailored to project location and regulatory requirements.

We understand that international projects require coordination across multiple frameworks, and we work with clients and partners to ensure alignment with applicable national regulations and recognized international standards, including guidance from the International Atomic Energy Agency (IAEA), as applicable.

Our support may include:

  • Coordination with in-country stakeholders, regulators, and technical partners

  • Alignment with local licensing, import/export, and transport requirements

  • Integration with approved transport packages and logistics providers

  • Support for documentation, planning, and execution consistent with international best practices

Where required, ATOM SPEC works alongside qualified local entities to ensure all work is performed in accordance with country-specific requirements and site conditions.

Why Choose ATOM SPEC?

Technical Expertise

ATOM SPEC personnel have experience in radiation safety, engineering, project management, and decommissioning activities. This background supports technically sound planning and execution across a range of facility and equipment types.

Regulatory Experience

We operate within multi-agency regulatory environments and develop documentation aligned with applicable requirements, including U.S. Nuclear Regulatory Commission frameworks and Agreement State programs.

 Safety First

Safety is integrated into all project phases, with emphasis on worker protection, environmental controls, and adherence to established safety programs.

 Project-Specific Approach

Decommissioning activities are planned and executed based on facility conditions, radiological hazards, regulatory context, and project objectives rather than a one-size-fits-all model.
