Description

Expected Outcome:

Project results are expected to contribute to all the following expected outcomes:

• Drafting of a R&I roadmap towards deploying nuclear power in commercial shipping, including small modular reactors (SMRs) and other advanced nuclear technologies (e.g. complementing the latest European Industrial Alliance on SMRs technology roadmap[1]), including identification of research gaps, infrastructures and future innovation needs

• Mapping of relevant regulatory regimes nationally, regionally and internationally for the use of nuclear-powered shipping, including recommendations on regulatory frameworks and international cooperation.

• Development of scenarios for the use of the technology, including potential damage scenarios.

• The implications for National Energy and Climate Plans and National Air Pollution Control Programmes as well as water pollution policies required by EU legislative framework.

• Assessment of total cost of ownership for the deployment of current and potential technologies.

• Development of safety, training and operational guidelines for nuclear-powered ships.

Scope:

Nuclear propulsion has the potential to reduce emissions of air pollutants and to decarbonize the shipping sector, producing zero GHG tank-to-wake emissions and low upstream well-to-tank emissions. A coordinated effort among various stakeholders including industry partners, research performing organisations, NGOs, the European Commission, the International Atomic Energy Agency (IAEA), and the International Maritime Organisation (IMO) should help evaluate such prospective potential. It should benefit from the latest Research and Innovation (R&I) results, technical, socio-economic and environment studies, or initiatives being capitalised at EU and international level, to ensure a comprehensive assessment.

The main objectives are to assess the feasibility, safety, and environmental impact of using nuclear power for shipping to achieve zero-emission of GHG, air and water pollutants in maritime transport. Following a preliminary assessment and literature review, as well as detailed technical and economic studies regulatory and technical recommendations should be developed, along with a review of on-going pilot projects aimed at demonstrating the feasibility of nuclear-powered vessels.

The project should help evaluate the technical, economic, regulatory, environmental and social aspects of deploying nuclear power in commercial shipping, including small modular reactors (SMRs) and other advanced nuclear technologies.

Actions should address all the following aspects:

• Technical Feasibility: a) To assess the suitability of SMRs and other nuclear technologies for maritime use; b) To evaluate any integration challenges with existing and potential new ship designs, including modular designs.; c) To study the lifecycle of nuclear-powered vessels, including construction, operation, and decommissioning.

• Economic Viability: a) To conduct cost-benefit analyses comparing nuclear-powered shipping to conventional and renewable low and zero-carbon fuel options, taking into account the long-term availability of fuel and the cost of disposal of residues; b) To evaluate infrastructure requirements in the EU, such as port facilities for nuclear vessels; c) Mapping full costs for a nuclear propelled ship on a life cycle basis.

• Safety and Security: a) To develop safety protocols for nuclear-powered ships, including emergency response and accident mitigation; b) To address cybersecurity risks, external threats and proliferation concerns and safety in ports. c) Assessing long-term crew training requirements for nuclear operations, safety and security and their implementation in international training and certification regulations.

• Environmental Impact: a) To analyze the potential reduction of greenhouse gas emissions, air and water pollutants caused by mining, refining, use and disposal of spent nuclear fuel; b) To assess the impact of nuclear waste management, disposal as part of implementation of a circular economy approach; c) To assess the impact of nuclear-powered ships on marine ecosystems addressing in particular water pollutions and by contaminants; d) To analyze possible damage scenarios with a view to liability issues and mitigation of damages.

• Regulatory and Legal Framework: a) To identify gaps in international maritime law and IAEA nuclear regulations; and b) To propose recommendations related to the International Convention for the Safety of Life at Sea (SOLAS)[2] and other relevant treaties

• The implications for National Energy and Climate Plans and National Air Pollution Control Programmes required by EU legislative framework.

• Additionally, a strategy for skills development should be presented, associating social partners and civil society where relevant.

Proposals are expected to demonstrate how their objectives contribute to EU added value and long-term competitiveness in nuclear-powered vessel technologies. This includes enhancing the EU’s R&I capacity, safeguarding critical technological know-how, developing skilled human capital, and reinforcing the resilience of the EU’s industrial and manufacturing base in this strategic sector.

This topic implements the co-programmed European Partnership on ‘Zero Emission Waterborne Transport’ (ZEWT). As such, projects resulting from this topic will be expected to report on results to the European Partnership ‘Zero Emission Waterborne Transport’ (ZEWT) in support of the monitoring of its KPIs.

Conditions6

Typed facts extracted from the source documents by Scindu's grant-data review. Each value keeps its own conditions. Unknown means unstated, not zero or unlimited.

Applicant restriction
Participation is subject to restrictions for protection of European communication networks; the reviewed topic clause does not itself enumerate the detailed restricted entities.
Applicant type
This topic is a Coordination and Support Action. General Annex B states that proposals for Coordination and Support actions may be submitted by one or more legal entities (with Member State or Associated Country establishment, except the specified third-country exception). The standard three-independent-beneficiary rule does not apply to this action type.
Application restriction
The MOBILITY call is scheduled to open 15 December 2026 and close 14 April 2027; the Work Programme states deadlines are 17:00 Brussels local time. This call window is scheduled, not evidence that applications are currently accepted.
Consortium required
No
Eligible project scope
Coordination/support study of nuclear power potential for commercial shipping, including technical, economic, regulatory, environmental and social assessment, roadmap/research gaps and safety/training guidance; it is an assessment and roadmap action, not a vessel-build grant.
Other condition
The call overview indicates around 1 project(s) expected to be funded for this topic. This is a planning estimate, not guaranteed awards or a binding consortium/project-count condition.
Amounts and costs7
Indicative budget

Topic budget as stated in the portal's budget table. Lump-sum and per-project limits are in the call conditions.

Call allocation
€131,000,000

Overall indicative CL5-2027-03 call-pool budget, not a per-project or per-beneficiary award; subject to availability of EU appropriations.

Eligible cost
If a project uses satellite-based Earth observation, positioning, navigation and/or related timing data/services, beneficiaries must use Copernicus and/or Galileo/EGNOS; other data/services may also be used.
Eligible cost
Personnel may be included as estimated cost categories in the lump-sum proposal budget, not separately reimbursed as actual payroll. Cost estimates must approximate actual costs, follow beneficiaries’ normal practices, be reasonable/non-excessive, align with proposed activities, and satisfy Horizon Europe basic eligibility rules.
