Steptoe advises clients across the full lifecycle of nuclear energy projects, from early‑stage development and licensing through construction, operation, and dispute resolution. The firm represents utilities, developers, investors, engineering, procurement, and construction (EPC) contractors, and technical assistance and information technology service providers on the complex governmental and geopolitical issues that shape nuclear projects in the United States and internationally. Steptoe utilizes regulatory, commercial, dispute resolution, and international trade capabilities to address the full scope of risks facing nuclear projects, providing clients with coordinated legal support for development and operation of such projects.
Steptoe's nuclear team includes lawyers who have clerked at the US Nuclear Regulatory Commission (NRC) and have had extensive dealings with that agency as well as the US Department of Energy (DOE). The firm advises on reactor licensing matters, including applications to the NRC, as well as energy regulatory matters that include capacity uprates, decommissioning, waste management, site selection, and land use permitting. With lawyers who have worked at the NRC and provided legal advice on reactor‑related regulatory and appellate matters, Steptoe brings an insider's understanding of regulatory processes, agency expectations, and how regulatory decisions intersect with enforcement and litigation risk.
A defining feature of Steptoe's nuclear capabilities is the depth of its export and import controls experience before US federal agencies regarding civil nuclear items, combined with the firm's longstanding national security and enforcement practice. Notably, clients seek out Steptoe for its ability to handle nuclear‑related export and import controls and international trade matters related to unenriched uranium alongside core nuclear regulatory work. In light of growing interest in civil nuclear power as a sustainable energy source, international opportunities have increased significantly. The firm counsels US and non‑US companies on compliance with the NRC, DOE's National Nuclear Security Administration (NNSA), US Department of Commerce's Bureau of Industry and Security (BIS), and US Department of the Treasury's Office of Foreign Assets Control (OFAC) obligations and requirements, including Part 810 or Part 110 export or import authorizations, deemed exports and deemed reexports, technology transfers, and cross‑border transfers, transactions, investments, and financings involving civil nuclear technology, commodities, materials, and software. This combination allows Steptoe to advise holistically on issues where nuclear development intersects with national security, foreign investment, and geopolitical risks.
Complementing its regulatory and trade capabilities, Steptoe advises clients on the commercial and project delivery aspects of nuclear facilities and related infrastructure. Most notably, Steptoe has experience in litigating nuclear-related regulatory and commercial disputes in US federal court and in international arbitration. Additionally, the firm represents sponsors, owners, EPC contractors, and lenders in connection with power purchase agreements, EPC contracts, and project financing arrangements. Drawing on extensive experience handling complex EPC and energy disputes in US courts and international arbitration, Steptoe helps clients structure nuclear projects to manage risks, anticipate disputes, and protect value throughout development, construction, and operation.
Representative Matters
Representative Nuclear Regulatory, Dispute, and Transactional Matters
Regulatory
- Advised a US oilfield services company about export control obligations under the NRC and BIS export control regulations relating to nuclear source material, radioactive isotopes and by-products, and radioactive material encapsulated in downhole oil well-logging tools.
- Advised a non-US nuclear research and reactor development organization on the interpretation of Part 810 requirements, including the extraterritorial reach of NNSA jurisdiction to a non-US entity's nuclear activity based on either US person ownership or control of the entity, US person management, or receipt and use of US-origin nuclear technology. The work involved the collection of extensive information from the non-US entity concerning its ownership, management structure, collaboration with US companies, commingling and use of US-origin technical information with indigenous technology, and the further dissemination of its technology inside and outside the host country.
- Advised and assisted a UK company and its US affiliate about Part 810 compliance in connection with a joint venture arrangement with a US company to develop and market small modular reactor (SMR) systems, including guidance on Part 810 reporting requirements, data storage consistent with US law, and deemed exports and reexports involving non-US nationals participating in the project.
- Providing a major US nuclear fuel company ongoing US and EU economic sanctions guidance, including navigating evolving Russia-related restrictions.
- Advised a US nuclear engineering and construction company on its Part 810 reporting obligations in connection with services provided for a nuclear facility outside the United States.
- Advised a US construction and engineering company with regards to export control compliance requirements when supporting a non-US nuclear naval fleet with its nuclear propulsion systems.
- Advised a US company on its export control compliance obligations under Part 810, and prepared reports to be submitted to the NNSA for Generally Authorized Destination (GAD) export activity, including with regards to the deemed export release of controlled technology to a GAD foreign national employed in the United States.
- Advised and assisted a non-US medical device company with export control compliance and the required licenses under either BIS' Export Administration Regulations (EAR) or NRC's Part 110 regulations on the , and/or OFAC's regulations regarding medical equipment and replacement nuclear sources for delivery to a US-embargoed country.
- Advised a US subsidiary about whether contemplated exports of certain components from the US would be considered “specially designed” under the EAR and whether it would require a US government license for export to a plant in Iraq. This representation involved direct communications with BIS, as well as indirect consultations with NNSA, about the appropriate US export commodity jurisdiction and classification of the subject items under the EAR for nuclear non-proliferation reasons of control (corresponding to Annex II of the Nuclear Supplier Group Guidelines).
- Evaluated the appropriate export control classification number and prepared a specific license request to BIS to export technology related to zirconium sponge for producing fuel assemblies in nuclear power plants, to a company in China.
- Undertook external investigations on behalf of non-US headquartered companies on the potential unauthorized export and subsequent transfer of foreign-developed nuclear technology commingled with US-origin nuclear technology and submitted voluntary self-disclosures to NNSA.
- Economic sanctions advice regarding the nuclear energy sector of the Russian Federation economy, as well as the scope of OFAC general licenses that may apply.
- Conducted high-stakes internal investigations for a public power producer within the nuclear energy industry. These included addressing whistleblower claims, allegations of retaliation, and chilled work environments at nuclear power plants.
- Represented various US government contractors on funding and loan agreements for major manufacturing projects in the energy, defense, and life sciences sectors.
- Advised a Korean energy company on participating in a DOE/NNSA manufacturing project involving SMRs.
- Advised a US nuclear safety company on research and development contracts with DOE/NNSA laboratories involving digital twins and clearances to access restricted nuclear data.

Steptoe successfully obtained a dismissal for our clients on the grounds that the plaintiff's effort to enforce the US Atomic Energy Act and Part 810 could not proceed because the complaint lacked a private right of action under US federal law. Steptoe also represented the clients in bringing an arbitration against the other party in the Korean Commercial Arbitration Board.
- Represented a Bulgarian company in an ICC arbitration against a subsidiary of a Russian-headquartered company regarding a civil nuclear energy power plant.
