What this call funds

Expected Outcome:

the project results are expected to contribute to some of the following expected outcomes:

  • research into safety of innovative reactors, small modular reactors (SMRs) – both light water SMRs (LW-SMRs) and Gen-IV-based advanced modular reactors (AMRs); design or demonstration of SMRs and fuel cycles’ viability; and efficient integration within low-carbon and smart energy systems;
  • research support towards a shared and consistent approach among regulators’ TSOs to safety requirements for different advanced energy systems and applications (e.g. industrial heat, district heat and the maritime sector), supported by regular exchanges and reviews and workshops with licensees, SMR developers, and research organisations, thereby further improving safety across the EU;
  • emphasis on innovation in the safety aspects of LW-SMRs and AMRs;
  • establishment of operating rules for specific services for innovative reactors, incorporating emerging instrumentation and digital technologies that offer potential improvements for in-service operation;
  • research into fuel cycles (including their key features: inherently safe design, generation of less high-level waste and improved use of resources), potentially enabling interested Member States to contribute to the energy transition (according to and respecting the EU’s technology neutrality principle) and thus increase Member States’ and EU energy security.

These are Bemzu's estimates from the call's structure (the number of stages and whether a consortium is required) not figures published by the Commission. Only the co-financing share is read from the call itself.

Where these conditions come from

Two kinds of row. Most are the sentence we read the condition from, quoted out of the call itself. Some say plainly that they are not a quotation but the programme's own rule for this type of action, the EU portal publishes a table of contents where the conditions should be, so for a Research and Innovation Action the rate comes from the rulebook rather than from the fiche.

ConditionQuoted from the call, or the rule behind it
Consortium sizeNot quoted from this call — Innovation Actions under the Horizon Europe rules are at least three independent legal entities from three different Member States or Associated Countries, at least one established in a Member State.
Funding rateNot quoted from this call — Innovation Actions under the Horizon Europe rules are funded at 70% of eligible costs for profit-making organisations, and 100% for non-profit legal entities — the rate shown here is the one that applies to a company.
