- Tortoise Nuclear Renaissance ETF (TNUK) is an actively managed exchange-traded fund that provides pure-play exposure to the global nuclear ecosystem, spanning the full value chain from mining and fuel cycles to reactor development, operators, and supporting services. The fund seeks to capitalize on the anticipated secular growth of nuclear energy as a reliable, low-carbon baseload power source amid rising electricity demand from digital infrastructure, electrification, and decarbonization initiatives. Headquartered in Overland Park, Kansas, Tortoise Capital Advisors manages the ETF as part of its energy and infrastructure investment platform, with a focus on selecting and weighting companies based on revenue ties to the nuclear industry and asset exposure. Founding and launch date reflect a strategic expansion into thematically driven, outcomes-focused exposure for institutional and sophisticated investors seeking diversified participation across the nuclear supply chain.
