Energy and Nuclear Apprenticeships 2027: Who's Hiring

There is one sector where the word "revival" isn't a communications slogan but a budget line: energy. Between the new EPR2 reactor programme, the major refurbishment of the existing fleet, the reinforcement of electricity grids to absorb wind and solar power, and the replacement of a generation of technicians reaching retirement age, the French energy sector needs tens of thousands of professionals by 2035. The Université des métiers du nucléaire (UMN), created by the industry's manufacturers, regularly puts forward the figure of 100,000 hires to be made over ten years for the nuclear sector alone. And unlike many sectors that recruit "experienced profiles", this one trains massively through apprenticeships, because its skills cannot be learned in a classroom.

In short: for the 2027 intake, the energy sector is recruiting apprentices at every level. Levels 3-4: CAP Électricien (electrician certificate), CAP Monteur en installations thermiques (thermal installation fitter), bac pro MELEC (electrical trades and connected environments), bac pro MSPC (maintenance of connected production systems), bac pro TMSEC (energy and climate systems maintenance technician), bac pro Métiers du froid (refrigeration trades), professional certificates in pipefitting, welding and scaffolding. Level 5: BTS Électrotechnique, BTS CIRA (industrial control and automatic regulation), BTS Maintenance des systèmes, BTS FED (fluids, energy, home automation), BTS Environnement nucléaire, BUT GEII, BUT GTE (thermal and energy engineering), BUT Mesures physiques, BUT HSE. Levels 6-7: professional bachelor's degrees in energy management and electrical grids, engineering schools offering apprenticeship tracks (ITII, Arts et Métiers, CESI, Polytech, INSTN for nuclear), master's degrees in energy. Employers: EDF (nuclear, hydro and thermal generation, R&D), Enedis, RTE, Orano, Framatome, CEA, Engie and its subsidiaries, GRTgaz and GRDF, Dalkia, Vinci Energies, Eiffage Énergie Systèmes, Spie, Onet Technologies, Nuvia, Assystem, Bouygues Energies, plus local electricity utilities and wind and solar developers. Campaigns mainly open from November 2026 to May 2027, with peaks in January-February and possible start dates right up to October 2027.

Why the energy sector is a favourable market for apprentices

Three dynamics are converging, and all of them work in candidates' favour.

The age pyramid. France's nuclear fleet was built between 1977 and 1999: the teams operating it were hired in waves and are leaving in waves. The same logic applies at Enedis and RTE, where the trades of line erector and grid operations technician are passed on through mentoring.

The projects. Flamanville, the six announced EPR2 units (Penly, Gravelines, Bugey), the major refurbishment extending the life of existing reactors, the decommissioning of shut-down facilities, the connection of offshore wind farms: each of these programmes mobilises thousands of maintenance technicians, welders, valve specialists, contract managers, site planners and quality inspectors.

Electrification. Heat pumps, charging points, data centres, industry switching from gas to electricity: distribution grids must be reinforced everywhere. Enedis announces several thousand hires every year, a significant share of them apprentices.

One principle to keep in mind before applying: in this sector, geographical mobility is your best argument. A candidate willing to move to Chinon, Golfech, Cattenom, Tricastin, Paluel or Civaux statistically has far better odds than one who insists on Paris or Lyon. Power plants are located in rural or peri-urban areas, and that is precisely where positions stay open the longest.

The major employers and their campaigns

EDF and the generation fleet

The group is, by a wide margin, the sector's leading trainer of apprentices: several thousand contracts in progress, spread across nuclear generation (the CNPE sites), hydro, thermal, engineering (Edvance, DIPDE), R&D, sales and support functions. Every plant publicises its "new apprentice intake" at the start of the academic year — Cattenom did so again in September 2026 — which gives a useful signal: volumes are renewed from one year to the next.

The timeline is stable. Offers for a September start are posted from November-December onwards, with a large volume in January and February, and campaigns closing gradually in April-May. Applying in July for September means picking over the leftovers.

The roles most widely open to apprenticeships: mechanical, electrical, automation and valve maintenance technician, surveillance officer, site logistics and operations, radiation protection, water chemistry and environment, safety and quality, and on the office side human resources, procurement, management control and communications.

The grids: Enedis, RTE, GRTgaz, GRDF

Enedis mainly recruits bac pro MELEC and BTS Électrotechnique holders for roles as grid intervention technician, connection fitter, customer service technician and connection project manager. RTE, the high-voltage transmission grid operator, targets BTS/BUT electrical engineering and engineering profiles (grid studies, substations, lines, control systems). GRTgaz and GRDF train gas maintenance technicians and grid customer advisers.

One specific point to know: these employers belong to the electricity and gas industries (IEG) branch, with its own collective agreement rules and its own training centres. Their campaigns are also aligned with January-March.

The fuel cycle and decommissioning: Orano, Framatome, CEA

Orano (mining, conversion, enrichment, recycling, decommissioning) recruits at its La Hague, Tricastin, Malvési, Melox and Bessines sites: chemists, process technicians, mechanics, nuclear logistics specialists, HSE staff. Framatome manufactures components and fuel: Le Creusot, Saint-Marcel, Jeumont, Romans-sur-Isère, Ugine. Welding, boilermaking, machining and non-destructive testing (NDT) trades are in especially high demand there, and very hard to fill. The CEA, for its part, trains apprentices at its centres (Saclay, Cadarache, Marcoule, Grenoble) and runs the INSTN, which awards specialised qualifications in nuclear engineering and radiation protection.

Contractors: the real pool of vacancies

This is candidates' blind spot. For every position at EDF, there are several at the contracting companies that carry out maintenance and refuelling outages: Onet Technologies, Nuvia (Vinci), Assystem, Spie Nucléaire, Eiffage Énergie Systèmes, Endel, Ponticelli, Clemessy, Bouygues Energies & Services, Dalkia. They recruit apprentices at the same levels, with selection processes that are often shorter and less competitive. Their vacancies are posted on their own careers sites and, for the nuclear sector, on the platforms run by GIFEN (the French nuclear industry association) and the UMN.

The qualifications that genuinely open doors

Two qualifications deserve a separate mention. The BTS Environnement nucléaire trains specifically for work in controlled areas: nuclear logistics, decontamination, decommissioning, intervention planning. It is taught at a limited number of institutions (notably Cherbourg, Bagnols-sur-Cèze, Montalieu and Chinon) and its graduates are highly sought after. The BTS CIRA is the other safe bet: instrumentation and process control are just as useful in nuclear as in chemicals, food processing or water treatment.

For candidates aiming at laboratory, measurement or testing roles, the article on laboratory apprenticeships in 2027 details neighbouring qualifications (chemistry, physical measurement) and employers that partly overlap with this sector.

The 2026-2027 timeline, month by month

• November-December 2026: first offers from EDF, RTE, Enedis and Orano for the 2027 intake. Low volume, but little competition. This is also the season for careers fairs and open days at industrial apprentice training centres.
• January-February 2027: the peak. Most large groups publish their apprenticeship offers. Engineering schools with apprenticeship tracks (the ITII network) open registration for their entrance exams, often with an application to submit before the end of March.
• March-April 2027: interviews, medical fitness examinations and, for nuclear, the launch of site access requests (administrative background checks). Allow several weeks: this is the main reason employers in the sector recruit early.
• May-June 2027: second wind. Unfilled positions are reposted, often at the most remote sites. Contractors do a lot of hiring at this point.
• July-October 2027: staggered start dates and replacements for withdrawals. The three-month window to find an employer after enrolling at a training centre applies here as elsewhere — our article on starting an apprenticeship without an employer explains the rules.

The three selection filters specific to this sector

1. Medical fitness and certification

Jobs in nuclear areas require an enhanced medical fitness examination (category A or B in radiation protection terms) and dosimetric monitoring. Electrical roles require electrical safety certifications (B1V, B2V, BR, H0V) awarded after training. These steps are non-negotiable: build them into your timeline. Our article on the apprentice medical examination sets out the applicable deadlines.

2. Site access

For nuclear power plants, Orano sites and classified installations, access is subject to an administrative background check. An incomplete file delays hiring, sometimes by several weeks. Respond quickly and in full to requests for documents.

3. Technical tests

Expect tests of logic, blueprint reading, arithmetic and sometimes electrical schematics. An electrical engineering textbook and a workbook of wiring-diagram exercises are more than enough to brush up before an interview: recruiters aren't looking for an expert, they're looking for someone who hasn't forgotten Ohm's law and can read a schematic diagram. For site-based roles, a pocket tape measure and a notebook remain the two items every mentor notices on day one.

Preparing your application: what makes the difference

Energy-sector recruiters read hundreds of identical CVs. Three concrete levers:

Document your mobility. State in black and white, in your cover letter, the sites you are willing to move to. A driving licence, even one in progress, is a genuine asset when the plant is 20 km from the station. On the housing side, the article on housing support for apprentices covers the schemes available when you relocate for a contract.

Show that you know the vocabulary. "Refuelling outage", "controlled area", "lockout", "operational feedback", "safety": using the right terms in a letter proves you've read more than the home page. An accessible book on nuclear energy or the public reports of the French nuclear safety and radiation protection authority (ASNR) are enough to build that foundation.

Sort out the practical side. Industrial sites require S3-rated safety shoes and PPE that the employer is in principle meant to supply; check this before the start date, and look into the first-equipment grant available in your region. For days at the training centre, a spiral-bound notebook remains more practical than a screen in a workshop.

Finally, prepare for the interview as you would for an industrial one: safety first, rigour second, and enthusiasm for hands-on work throughout. Our general advice on succeeding at your apprenticeship interview applies, provided you add the safety dimension, which is the first question asked in this sector.

And after the contract?

This is the sector's strongest argument: the conversion rate into permanent employment is high, because the training investment is heavy (certifications, site access, mentoring) and employers have no interest in letting a trained apprentice walk away. Classic career paths: maintenance technician → surveillance officer → team leader; or grid technician → project manager → activity management. Many apprentices continue internally all the way to an engineering degree through an apprenticeship track.

To compare with other industrial sectors on similar timelines, see aerospace apprenticeships 2027: same qualification levels, same shortages in welding and NDT, but very different employment hubs.

Key takeaways

• The energy sector recruits from vocational certificate to engineering degree level, with acute shortages in maintenance, electrical engineering, welding, boilermaking and inspection.
• The 2027 campaigns open as early as November 2026 and peak in January-February 2027: applying late means missing out on the best positions.
• Beyond EDF, Enedis, RTE and Orano, maintenance contractors concentrate a volume of vacancies that candidates under-exploit.
• Plan ahead for certifications, medical fitness and site access: these are the sector's real lead times.
• Geographical mobility is, in this sector more than any other, the leading differentiating criterion.
