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.

Nuclear electrical production share projections in Europe 2024-2050, by scenario
Nuclear power's share of electricity generation in Northern, Western and Southern Europe stood at almost ** percent in 2024. Nuclear energy's contribution to electricity generation is forecast to decrease in the coming decade, declining to about ** percent by 2050 in a high case scenario. In the opposite scenario, this percentage would decrease to approximately ** percent. Similar projections for the nuclear share of electricity generation in North America show figures as low as *** percent if nuclear power is not promoted.
