According to the source, the low case scenario assumes that current market, technology, and resource trends will continue; few additional changes in laws, policies, and regulations concerning nuclear power will be made. No assumptions concerning targets for nuclear power are made.
The high case scenario takes into account existing policies as well as publicized intentions of individual countries regarding expansion of nuclear power use. While more ambitious, the high case projections are still plausible and technically feasible.

Global nuclear energy share in power production mix forecast 2024-2050, by scenario
The share of nuclear power in global electricity generation stood at *** percent in 2024. In a scenario in which countries pursue policies of nuclear power expansion, the share of nuclear power in the global power mix is forecast to reach almost ** percent by 2040. On the contrary, in a scenario where no policies for the expansion of nuclear power are implemented, the nuclear share of electricity generation would decrease by around ** percent between 2024 and 2050.
