Selecting the best exchange-traded fund (ETF) for nuclear energy exposure depends on an investor's focus between mining operations and clean utility infrastructure. Prominent options heavily favored by sector investors include the Global X Uranium ETF (URA) and the Sprott Uranium Miners ETF (URNM), both of which concentrate heavily on global uranium producers and physical yellowcake trusts. For broader clean energy portfolios encompassing nuclear plant operators and technology developers, alternative clean energy funds provide diversified alternative choices.
