Daniel F. Stenger

A leading advocate for nuclear energy clients, Dan Stenger brings more than 30 years of nuclear energy experience to helping clients obtain licenses and other regulatory approvals from the Nuclear Regulatory Commission (NRC) and Department of Energy (DOE). He represents companies before both agencies as well as before Agreement States and federal courts. Chambers USA (2013) praises Dan as "an excellent nuclear lawyer."

Dan handles the licensing and regulation of nuclear power plants and nuclear fuel cycle facilities under the Atomic Energy Act. He has handled combined license proceedings and design certification for new reactors under the NRC's Part 52 regulations, including for new technologies like small and modular reactors, as well as license renewal to extend the lives of existing nuclear plants.

Dan has also assisted clients on several ground-breaking mergers and acquisitions and restructuring transactions in the nuclear industry. These transactions include NRC license transfers associated with acquisitions of nuclear facilities and utility mergers involving foreign ownership issues. He also handles investigations and NRC enforcement actions, as well as whistleblower cases before the NRC and the U.S. Department of Labor.

As the international nuclear power market has expanded, Dan assists clients in obtaining authorizations from DOE under its Part 810 regulations on nuclear export controls. He also advises clients on nuclear liability and insurance issues under the Price-Anderson Act and international conventions.

Dan litigates in federal court on nuclear matters, including judicial review of NRC and other agency action in the U.S. Courts of Appeals.

"...an excellent nuclear lawyer."
