D&D Support, Facility Closure, Regulatory Support – Idaho National Laboratory

As prime contractor to the Idaho Cleanup Project (ICP) management and operating (M&O) contractors (Bechtel BWXT Idaho and CH2M Hill WGI Idaho), Portage has performed $55 million of program and project management work for the Department of Energy at the Idaho National Laboratory. The work has included support of decontamination and demolition (D&D), development of regulatory closure documentation, nuclear waste facility closure and associated technical writing, “de-construction” activities and construction management oversight of nuclear production and waste processing facilities and systems, and records management.

Idaho National Lab logo Portage has supported the ICP M&O contractors in their environmental cleanup mission since 1998. Our current task orders in support of the ICP range in size from $100,000 to $8,000,000. Our cleanup support has included a full spectrum of regulatory support services, D&D support of a nuclear radiological hot cell liquid waste system, treatment of sodium-bearing waste, removal of transuranic (TRU) waste from subsurface disposal, and general nuclear engineering support for construction demolition of more than 200 structures, including nuclear reactors, spent nuclear fuel storage basins, and laboratories used for radioactive experiments.


  • Support of the nuclear high-level waste subsurface Tank Farm closure addressing the safety management program, regulatory analysis and technical document development, modeling, sampling, and mockup demonstrations.
  • Support for all aspects of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) regulatory process for complex nuclear facilities with multiple waste types, including TRU and high-level waste.
  • Environmental and civil engineering, code analysis/compliance, and remediation services to the buried TRU waste retrieval projects at the Radioactive Waste Management Complex.
  • Regulatory research, technical document writing, records management, and final preparation of a Voluntary Consent Order for Resource Conservation and Recovery Act and CERCLA documentation supporting accelerated nuclear site cleanup.
  • Comprehensive engineering and quality assurance support of remediation for radiological waste disposal to meet waste acceptance criteria for disposal and related regulatory reports.
  • Continuing services in support of radiological control, nuclear and radiological containment/ventilation design, safety analysis, material accountability tracking, government property management, waste management planning (packaging, transportation, facility acceptance criteria, inventory control), and cutting-edge research and development of innovative nuclear facility and systems remediation technologies.
  • Nuclear/civil engineering design and Environmental, Safety, and Health support for D&D of radiological facilities and systems, including associated piping, vessels, and hot waste system.
  • Development and implementation of health and safety management program plans to support complex D&D of systems.
  • Research and completion of the first successful high-level waste Tank Farm closure documents.
