The ECOSENS project includes an assessment of the sustainability performance of the nuclear power for
the entire life cycle considering the current development of nuclear technologies together with the
investigation of the evolutions of the energy market in the transition toward climate neutrality in order to
discuss the role of the nuclear power in the medium and long term.
In this deliverable, a set of scenarios for nuclear power development in the European Union at the horizon
of 2050 was developed, based on the previous ECOSENS investigation of energy demand, existing
policies for decarbonization, and impact of societal and technological changes on the future energy
market. The key steps of the methodology for scenarios’ building are: identification of key drivers,
defining the alternative scenarios, checking the plausibility and consistency, narrative construction. After
that an iterative process involving stakeholders and decision-makers is necessary to strengthen the
scenarios, followed by testing the scenarios, and finally their use in the decision-making process. This
process will be achieved by the exploitation of results and will be based on the transfer of the results to
the potential beneficiaries such as the European and national decision-makers.
After an introduction briefly recalling the present status and historical development of nuclear power
especially in the European Union, the second section is devoted to the methodological considerations for
scenario building. A summarized presentation of Net Zero Emissions energy scenario is included to
understand the elements describing the normative elements of the visions and policies. Some existing
energy scenarios for the Europe Union development are also discussed.
The third section presents the approach used to handle the complexity resulting from the long-term
perspective of the scenarios and the multitude of uncertainties, for example those related to evolutions in
key parameters, and in technological and societal development. For the twelve established key
influencing factors, the first simplification was to reduce to six the number of factors having a broad
spectrum of variation. Six factors (decarbonization, grid modernization, interconnectivity, resilience and
adaptation, global cooperation, and carbon capture) were considered with evolutions described by the
current vision of the climate neutrality or those normative scenarios derived from net zero emissions. The
broad variation of the other six factors (renewable energy, electrification, energy storage, energy
efficiency, behavioral changes, and technological assessment) was considered and detailed in three
scenarios (high, medium, and low).
By considering the most relevant cases of the variation of the previous key factors, a set of four scenarios
for nuclear power development is developed and presented in the fourth section. The scenarios are:
Nuclear Status Quo (unchanged pace of nuclear development, not much influenced by an acceleration of
renewables), Nuclear Phase-Out (no new nuclear project, progressive phase-out), Nuclear and
Renewables Synergy (nuclear to support accelerated implementation of renewables), and Nuclear
Renaissance (nuclear accelerated by the new reactor technologies).
A discussion on the plausibility of these four scenarios is presented in the fifth section, followed by the
construction of the narrative of each scenario. Further steps (an iterative testing process involving
stakeholders) are mentioned, followed in the sixth section by the main conclusions for the whole work.
