Design of an innovative Small Modular Reactor

SMR Programme

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™.

This kind of reactor aims to meet the significant needs for the supply of carbon-free electricity, instead of fossil fuel power plants, while being easier to finance than large reactors, and easier to make fit in the electricity transmission networks

Simplicity and compactness of an integrated design.

Flexibility during the construction and operation phase.

An innovative approach to safety in keeping with the highest global standards.

Main services

  • Design and development of the nuclear steam supply system (reactor).

  • Design of the reactor core.

  • Development of innovative technological blocks to improve product competitiveness.

An innovative reactor:

Easy to build : A simplified design, both in its general architecture and in the design of its components.

Easy to assemble : a compact modular design and an integrated architecture

Easy to operate : The assembly of several modules makes for flexibility in operation and maintenance.

A new approach to safety : With the innovations used in it, the SMR has passive safety mechanisms, meets all the Generation 3 safety requierements and offers additional margins.
