TECHNICATOME
Business trends
	
 TechnicAtome revenues reached €633 million in 2024 (+15.1% year-on-year), of which approximately 85% 
from defence activities. The group recorded a profitability level of 14% in 2024 and had an order book of 
€1.8  billion at the end of the year, representing nearly three years of sales.
	
 TechnicAtome is a major player in nuclear marine propulsion for French Navy submarines and aircraft carriers. 
The group is also involved in project management assistance for the infrastructures of the Brest and Toulon 
naval bases. In particular, it conceives the programme to adapt the ports’ basins.
	
 In October 2024, TechnicAtome and Onet Technologies jointly acquired TechnoPlus Industries (TPI), a French 
precision engineering company operating in the military and civil nuclear sectors as well as in aeronautics 
(notably with Airbus). TechnicAtome became the majority shareholder in TPI, owning 70% of shares.
	
 At the end of 2024, TechnicAtome withdrew from the French Nuward small modular reactor (SMR) project, led 
by EDF with the CEA and Naval Group.	
	
	
	
 In March 2025, TechnicAtome and Framatome jointly acquired the French company Segault, owned by the 
Canadian group Velan. Segault (80 employees, €11 million in revenue in 2023) specialises in valves for extreme 
applications, intended for the civil and military nuclear industries. Its products are used in particular in the 
nuclear reactors of French nuclear submarines (SSNs and SSBNs) and the Charles de Gaulle aircraft carrier. 
With this acquisition, worth approximately €170 million, TechnicAtome and Framatome aim to secure their 
supplies.
	
 In June 2025, TechnicAtome inaugurated two buildings at its site in Aix-en-Provence (in southeastern France), 
which employs more than 800 people. Covering an area of more than 4,000 m² and intended for engineering 
teams, the new buildings will be able to accommodate nearly 300 people.

 TechnicAtome is involved in the Barracuda programme for the construction of six new-generation Suffren-
class nuclear-powered attack submarines (SSNs) by 2030. The group is in charge of the design, production 
and maintenance of the nuclear reactors, their support system and their fuel. The submarine named Tourville, 
the third unit in the programme, entered active service in July 2025. The launch of the fourth submarine, named 
De Grasse, is scheduled for 2026.
	
 Construction of the first of the four future third-generation SSBNs (SNLE 3G, in French) began in March 2024 
with the first steel cutting. Naval Group is the prime contractor for the overall construction of the submarines, in 
partnership with TechnicAtome, which will build the nuclear reactors.
	
 In April 2024, Naval Group and TechnicAtome received notifications to begin construction of the nuclear 
reactors for the future French aircraft carrier (PA-NG, in French), scheduled to last until 2029. TechnicAtome 
will supply two new-generation K22 reactors, more powerful and with extended autonomy. Commissioning of 
the PA-NG is currently scheduled for 2038.
	
 TechnicAtome and Vanatome (a company acquired in mid-2024 by Framatome and TechnicAtome) signed 
an agreement in November 2024 to cooperate until 2037 in the field of hydraulic valves (R&D, production and 
maintenance) intended in particular for French third-generation SSBNs and future aircraft carrier (PA-NG).
Technology and Innovation
	
 TechnicAtome participates in the Mecanum collaborative R&D project, which aims to develop digital twins for 
nuclear facilities. Part of the France Relance programme, this project is led by EDF and involves Framatome, 
the CEA, Orano (formerly Areva) and Naval Group.
