North American construction is back—smaller and faster—at OPG’s Darlington
“The nuclear renaissance is real here,” said Ontario Power Generation’s Subo Sinnathamby on May 8, one year to the day after OPG secured a final investment decision to build the first of four planned BWRX-300 reactors at its Darlington nuclear power plant, and shortly after the new reactor’s foundation was lifted into place. “We got our license to construct in April and our [final investment decision] in May, and we’ve been off to the races since.”

Director of Fuel Cycle Technology
Oklo
Dr. Christina Leggett is the Director of Fuel Cycle Technology at Oklo Inc. In this role, she oversees the team that is designing Oklo’s Fuel Recycling Facility, which will be sited in Oak Ridge, TN. Prior to working at Oklo, she was a lead engineer at Booz Allen Hamilton, where she worked as a nuclear technology advisor for the Department of Energy’s (DOE’s) Advanced Research Projects Agency-Energy (ARPA-E). In this role, she served as the lead technical advisor for the ARPA-E CURIE program, which focused on enabling the economic and secure recycling of the Nation’s existing used nuclear fuel (UNF); supported the development and implementation of several ARPA-E nuclear programs, most notably the ONWARDS and NEWTON programs focused on reducing advanced reactor and fission product waste; and provided technical oversight for approximately two dozen ARPA-E-funded nuclear fission and fusion projects. Dr. Leggett also worked as a federal program manager in the DOE Office of Nuclear Energy and as a nuclear engineer and reactor systems engineer at the U.S. Nuclear Regulatory Commission. She holds a Ph.D. in nuclear engineering from the University of California-Berkeley and is very passionate about UNF recycling coupled with advanced reactors as an integral part of a sustainable nuclear future and mentoring the next generation of nuclear professionals. She is also very active in the American Nuclear Society (ANS), having served on the ANS Board of Directors and as Chair of the Fuel Cycle and Waste Management Division.
