What Numark Associates does

NUMARK Associates, Inc. is a Bethesda, Maryland-based energy and environmental consulting firm founded in 1991 that delivers technical support, research, and management services to U.S. and international government and private-sector clients. The firm operates principally as a Technical Support Organization (TSO) to nuclear safety regulators, with established TSO roles for the U.S. NRC since 2007, UAE FANR since 2010 (supporting the Barakah Nuclear Power Plant across all four units), and Poland's PAA since 2023. Its service lines are Nuclear Regulatory and Research Services, Nuclear Facilities Support, Sustainable Energy and Energy Efficiency, and Support to U.S. Government Energy Assistance Programs.

NUMARK's underlying technical assets include the FAVOR probabilistic fracture mechanics code for reactor pressure vessel integrity assessment (refactored to the Fortran 2018 standard) and the public REAP radiation embrittlement archive database, both maintained and deployed on behalf of the NRC. The firm additionally supports high-temperature and advanced non-light water reactor materials analysis, digital instrumentation and control regulatory risk-informing, advanced reactor inspection program frameworks, and Environmental Impact Statement review for fuel fabrication facilities.

The firm generates revenue through task-order awards under multi-year IDIQ contracts with agencies including the NRC, USAID, USTDA, and international regulators such as UAE FANR. Disclosed IDIQ ceilings range from $8M (NMSS) to $200M (NRC Enterprise-Wide unrestricted), with specific task orders such as the Laos Energy Security Activity ($13.2M, 5 years) and Pakistan Power Sector Improvement Activity ($23.5M, 4 years). Customer concentration is materially skewed to a small set of federal and foreign-government clients, supplemented by selected advanced reactor developers such as Nuclea Energy.

Core offering

NUMARK Associates provides multidisciplinary nuclear safety and energy consulting services under Technical Support Organization (TSO) arrangements for government regulatory authorities. Core offerings include technical support for nuclear regulator reviews and licensing, nuclear facility safety and decommissioning support, sustainable energy and clean technology policy advisory, and USAID-funded international energy development assistance in countries such as Laos and Pakistan.

Product overview

NUMARK Associates is a consulting firm providing technical support, research, and management services rather than a product-based company. Their offerings consist of five interconnected service areas: Nuclear Regulatory and Research Services (providing technical support to nuclear regulators including NRC, FANR, and international authorities); Nuclear Facilities Support (consulting for nuclear facility operators on safety, operations, and decommissioning); Sustainable Energy and Energy Efficiency (policy and market research for clean energy technologies); and USAID Energy Assistance Programs (international development support in developing countries). The company operates as a Technical Support Organization (TSO) assembling multidisciplinary nuclear safety experts, combining licensing perspectives from North American and European regulators. Their services are delivered through integrated teams including partners such as VTT Technical Research Centre (Finland), TÜV NORD EnSys GmbH (Germany), and Lightbridge Corporation (USA), supporting nuclear industry activities since 2007.
