Small Modular Reactor (SMR)

With its wealth of experience in compact nuclear reactors, TechnicAtome innovates with the design of a small modular power reactor.

TechnicAtome, within a French partnership supported by the State, is developing a small modular reactor (340 MWe), which will be based on a pair of nuclear steam supply systems (NSSSs) with an equivalent power of 170 MWe each. Together with French nuclear power industry leader, EDF, TechnicAtome, the CEA and Naval Group are working on the development of this French initiative named NUWARD™.

An innovative reactor:

Easy to build

Thanks to a simplified design, both in its general architecture and in the design of its components.

Easy to assemble

By virtue of its modular design, its compactness and its integrated architecture.

Allowing a new approach to safety

With the innovations used in it, the SMR has passive safety mechanisms, meets all the Generation 3 safety requirements and offers additional margins.

Easy to operate

The assembly of several modules makes for flexibility in operation and maintenance.
