Nuclear power and uranium mining are contentious due to the long-term environmental risks, including radioactive waste disposal and potential for catastrophic accidents. Investors might steer clear of the nuclear sector or choose to engage with companies to promote safety and sustainability in operations.

Fund managers adopt a cautious approach towards investments related to nuclear power and uranium mining. Some funds entirely exclude companies involved in nuclear fission electricity generation, uranium mining, or nuclear fuel processing from its investment portfolio. Similarly, other funds enforce strict revenue thresholds, often not investing in companies that derive significant income from the nuclear sector, generally limiting this to 5%. Additionally, some funds permit investments in nuclear medicine due to its medical utility but exclude companies associated with nuclear weapons and uranium mining for energy production.
