Ryan K. Lighty represents and advises domestic and international businesses and government entities regarding litigation, transactions, and regulatory matters involving nuclear reactors and nuclear materials. Ryan regularly counsels clients on a range of complex issues associated with obtaining, amending, renewing, transferring, and terminating licenses from the US Nuclear Regulatory Commission (NRC). Ryan helps utilities and electric industry clients achieve sustainability, ESG, and climate change goals through nuclear plant license extensions and deployments of new nuclear technologies. He also counsels companies on the use of small modular reactors (SMRs), advanced reactors, and micro-reactors for non-traditional uses, including production of hydrogen, medical isotopes, industrial process heat, and power for data centers and crypotocurrency mining operations.
Ryan has represented NRC licensees as counsel of record before the NRC’s Atomic Safety and Licensing Board (ASLB) and the Commission in more contested adjudicatory proceedings than any other attorney in the past ﬁve years, and has litigated a variety of technical, environmental, and ﬁnancial matters. He also routinely guides clients on multifaceted regulatory compliance issues related to ﬁtness-for-duty and work hour requirements, access authorization, ﬁrearms regulation, physical and cybersecurity, radiological decommissioning, and Controlled Unclassiﬁed Information (CUI). He also holds a Top Secret "Q" clearance and is part of the ﬁrm's Classiﬁed Information Services practice.
Ryan also helps employers navigate government ethics restrictions applicable to current and former federal agency employees, and provides assistance to clients regarding the Freedom of Information Act (FOIA) and protection of trade secrets and confidential commercial information. Additionally, he advises clients regarding energy eﬃciency standards established by the US Department of Energy (DOE). Before joining Morgan Lewis, Ryan was an attorney in the NRC’s Oﬃce of the General Counsel and served as acting regional counsel in the agency's Region III oﬃce.
