World Nuclear Exhibition 2027

7–9 December 2027
Parc des Expositions, Villepinte, Paris, France

World Nuclear Exhibition (WNE) is a professional B2B exhibition for the civil nuclear industry. It covers the supply chain from fuel-cycle activities and reactor construction to power generation, operations, maintenance, waste management and decommissioning. The 2027 edition is scheduled for Paris Nord Villepinte; the organiser’s practical-information page gives the address as ZAC Paris Nord 2, 93420 Villepinte.

WNE is reserved for professionals working for or in the civil nuclear industry. Its 2025 edition brought together more than 1,070 exhibitors and more than 36,000 participants, alongside 24 pavilions and a programme of conferences and business meetings. The next edition’s exhibitor list and detailed programme should be checked as they are released.

Why Paris World Nuclear Exhibition matters

See the breadth of the civil nuclear supply chain

WNE brings together suppliers from across a complex industrial ecosystem. Published activity groups include fuel production and reprocessing, reactor engineering and construction, plant operations and maintenance, industrial equipment, safety services, waste management and decommissioning. The breadth can help visitors connect a technical requirement with adjacent equipment, services or suppliers.

Compare technologies and supplier capabilities

Equipment suppliers, engineering companies and service providers can present their expertise to a professional audience. Buyers and technical teams may compare specifications, documentation, service scope and project fit. A conversation or display is a starting point for due diligence, not a substitute for technical qualification or procurement review.

Put technical discussion beside commercial exchange

The 2025 edition recorded 9,000 business meetings, while the organiser describes pre-arranged meetings as one of WNE’s features. Confirm the 2027 meeting format when details are published. The earlier figure shows the event’s business orientation, but does not guarantee meetings or commercial outcomes for an attendee.

WNE reported more than 1,070 exhibitors, more than 36,000 participants, 45% international exhibitors, 25% international participants and 24 pavilions in 2025. These are previous-edition figures, not forecasts for 2027.

Who should visit Paris World Nuclear Exhibition?

Utility and plant operator teams

Useful if you are responsible for operating, maintaining or upgrading nuclear facilities. Focus on suppliers relevant to plant requirements, including major equipment, instrumentation, maintenance, industrial services and technical support. Prepare the issues to investigate and the documents or qualifications your organisation requires.

Procurement and supply-chain professionals

Use the breadth of the civil nuclear supply chain to compare companies across components, engineering, materials, testing, logistics and specialist services. Record product scope, technical documentation, service coverage, quality credentials and follow-up contact. Confirm company and product qualifications through your own procurement process.

Engineers, technical specialists and R&D teams

Published categories include reactor construction, advanced nuclear technologies, fuel-cycle activities, instrumentation, industrial equipment, operations and maintenance, radiation protection and decommissioning. Technical visitors can compare approaches and discuss interfaces, materials, operating conditions and evidence. Check the 2027 programme before planning around sessions.

Technology suppliers and service companies

Manufacturers, engineering firms and specialist providers may use the exhibition to explain relevant capabilities and understand professional needs. Establish which products or services apply to nuclear settings, prepare concise technical information and identify the organisations you want to meet. The 2025 exhibitor figure indicates scale, not guaranteed buyer access.

What makes Paris World Nuclear Exhibition different?

Its focus is the civil nuclear ecosystem across the value chain, rather than a single component or project stage. WNE’s scope extends from fuel-cycle services and reactor construction to plant operation, industrial supply, safety, waste and decommissioning. This makes cross-sector comparison relevant to professionals whose work depends on several specialised suppliers or interfaces.

The 2025 edition added a dedicated space on applications beyond power generation, including medicine, agriculture and food security, space exploration, low-carbon hydrogen, urban and industrial heat, and desalination. The previous programme also included innovation awards, startup activities, training and employment initiatives, conferences and business meetings. These are examples of 2025, not confirmed 2027 features.

What should you try to achieve at Paris World Nuclear Exhibition?

If you work in operations or maintenance

Define a short list of equipment or service needs to investigate. Note operating conditions, interface requirements, maintenance constraints and the evidence your technical team needs. Identify suppliers able to provide relevant documentation and service scope.

If you are a buyer or procurement professional

Compare a defined group of suppliers against the same criteria. Record technical fit, quality documentation, delivery and service questions, and the internal stakeholder who must review each supplier. Do not make a purchasing decision from a brief exhibition conversation alone.

If you are an engineer or technology specialist

Identify approaches worth a deeper technical review. Compare operating principles, materials, integration needs, maintenance implications and available evidence. Request documentation for formal assessment when a claim affects safety or performance.

If you are exhibiting

Choose the audience and technical question your stand should serve. Prepare clear product scope, application boundaries, supporting documentation and an appropriate next step for qualified enquiries. The organiser’s visitor and exhibitor totals do not guarantee leads.

How to prepare before Paris World Nuclear Exhibition

1. Define your purpose

Choose whether your priority is supplier discovery, equipment comparison, technical learning, partnership development or presenting a capability. Write down the decisions you hope to inform and the questions needed to inform them.

2. Build a target list as information becomes available

The organiser’s website provides exhibitor information for 2025. Check for the 2027 list when published, then identify relevant companies by product scope and activity. Do not assume a previous-edition exhibitor will return.

3. Prioritise conversations

Group companies into A: directly relevant to a defined need; B: useful for comparison or a potential partnership; and C: explore if time allows. If the organiser confirms a 2027 meeting service, request meetings with priority contacts and leave time for unplanned technical discoveries.

4. Prepare nuclear-industry questions

• Which equipment, systems or services are within the supplier’s scope?
• Which operating conditions, materials and interfaces does the solution support?
• What specifications, qualification records or test evidence can be shared?
• How are inspection, maintenance, repair and replacement handled?
• Which safety, radiation-protection or quality requirements apply to the intended use?
• What are the product’s limitations and dependencies on other systems?
• What documentation is available for engineering and procurement review?
• What service coverage, training or technical support is available?
• Which project stage or facility type is the product designed for?
• What information should be exchanged before a technical follow-up?

5. Plan for professional access

WNE states that the exhibition is reserved for civil nuclear industry professionals and that an identity card is required at the entrance. Check current admission and registration requirements before travelling.

How to make the most of Paris World Nuclear Exhibition

Use a consistent record after every supplier or technical conversation: Company → Product or service → Why it is relevant → Evidence requested → Contact → Next action. For example, record a maintenance technology separately from the plant system it interfaces with, note operating conditions discussed, and assign a technical owner to review documentation.

Compare like with like. A component manufacturer, engineering contractor and maintenance provider may address different parts of the same need. Keep their offers distinct and identify interfaces or gaps for follow-up. If meetings or a digital planner are confirmed for 2027, use them to protect time for priority conversations.

Plan your time realistically at Paris World Nuclear Exhibition

WNE spans many civil nuclear activities and the 2025 edition reported more than 1,070 exhibitors. A three-day visit can support distinct objectives rather than an unstructured tour.

• Before the first day: review the exhibitor and programme information, if available, and mark priority companies and sessions.
• Day one: orient yourself to the hall and focus on high-priority suppliers or technical areas.
• Day two: compare alternatives, attend relevant confirmed sessions and use planned meetings for detailed questions.
• Day three: revisit priority contacts, clarify outstanding information and organise follow-up.

Adjust the plan to the 2027 floor plan, opening times and published programme. Check these details with the organiser before the visit.

Beyond the Paris World Nuclear Exhibition floor

The 2025 edition listed 140 conferences, 334 speakers, four conference areas and 11,416 conference participants. It also featured 109 announced innovations, an Innovation Awards ceremony, startup activities and a dedicated space for applications beyond electricity. These examples show the previous edition’s range, not a confirmed 2027 schedule. Use the next programme to select sessions relevant to your technical, policy or project-delivery questions.

Networking at Paris World Nuclear Exhibition

The organiser reported 9,000 business meetings in 2025 and describes pre-organised business meetings as part of WNE’s format. Confirm the 2027 service and eligibility before relying on it. Prepare a short introduction to your role, project or product area, the technical information you need and a realistic next step.

For each conversation, agree what information can be shared and who should follow up. A specific request for a specification, qualification record or service overview is more actionable than a general promise to reconnect. Keep technical, commercial and regulatory questions distinct.

Travelling to Paris World Nuclear Exhibition

The organiser identifies the RER B station “Parc des Expositions” as the direct public-transport stop for the venue and describes RER B access from Paris and Paris-Charles de Gaulle Airport. The venue address published for 2027 is ZAC Paris Nord 2, 93420 Villepinte. Check current transport arrangements, event access information and opening details before travelling.

One day or several days at Paris World Nuclear Exhibition?

• One day may suit you if you have a short, defined supplier list or a small number of sessions. Prioritise meetings and product categories tied to your work.
• Two days may be useful if you need to compare suppliers, combine technical sessions with exhibition visits, or cover more than one supply-chain area.
• Several days may suit a broader objective involving multiple technical areas, meetings and follow-up conversations. Use the published 2027 floor plan and programme to decide whether all three days are relevant.

Paris World Nuclear Exhibition for a project team

If you are exploring a plant upgrade, component replacement, maintenance requirement, engineering service or decommissioning activity, agree on the project stage and information that can be shared. Prepare specifications, interface constraints, operating conditions, technical standards and review responsibilities. Avoid disclosing sensitive facility or security information in an open exhibition conversation. Ask suppliers what documentation they can provide for formal technical and procurement review.

After Paris World Nuclear Exhibition: where the value starts

Sort contacts into three groups: A — immediate technical or procurement follow-up; B — relevant for later comparison or planning; and C — useful market or technology information. For each A contact, assign an owner and date for the next step. Request material needed to assess fit, such as specifications, qualification evidence, maintenance scope or service terms.

Share findings with engineering, safety, operations and procurement stakeholders. Record what remains unverified, compare suppliers against consistent criteria and distinguish an initial discussion from an approved technical or commercial decision.

Who should consider exhibiting at Paris World Nuclear Exhibition?

WNE’s scope includes civil nuclear equipment and services across the fuel cycle, reactor construction, operations and maintenance, industrial supply, testing and certification, safety, radiation protection, waste management and decommissioning. Companies whose products or expertise serve these areas may assess whether the professional audience matches their objectives.

Before committing, define target organisations and roles, the technical questions your team can answer, the documentation you can provide and your follow-up capacity. The 2025 edition reported more than 1,070 exhibitors, 45% international. This demonstrates the previous edition’s international mix, not a 2027 forecast or a promise of buyer access.

Civil nuclear opportunities in France

Market size and demand

France generated 373.0 TWh of nuclear electricity in 2025, according to RTE’s annual electricity review. This actual generation figure indicates the scale of nuclear power in the country’s electricity system; it is not a measure of supplier revenue, procurement demand or future orders.

Regulatory context and commercial implications

The French Authority for Nuclear Safety and Radiation Protection (ASNR) states that it oversees civil nuclear activities in France on behalf of the French State. Product-specific approvals and technical requirements depend on the activity and intended use; companies should verify applicable rules with the relevant authority and project stakeholders. The information reviewed here does not establish a specific market-entry route or supplier qualification.

What this may mean for exhibitors

Suppliers of equipment, engineering, operations and maintenance services, safety technologies or decommissioning solutions may use WNE to explain their capabilities and compare their offer with needs professionals describe. The national generation figure provides context for the sector’s operating scale, but no segment-level supplier demand was identified and participation does not guarantee commercial results.

What this may mean for visitors

Utility, engineering and procurement professionals may use the exhibition to compare technologies and services against operational, technical and qualification requirements. The 2025 generation total is broad market context; buyers should assess each product, supplier and application on documented merits.
