SMR projects

Nearly eighty small modular reactor (SMR) projects are currently being developed around the world, including around ten in France.

Overview of current projects

The SMR projects monitored by the ASN and the Institut de Radioprotection et de Sûreté Nucléaire (IRSN) are as follows:

Nota: the Nuward SMR project, developed by an EDF subsidiary, is part of the continuity of the pressurised water reactor system currently used in French nuclear power plants. As such, it is monitored by the Nuclear Power Plants Division (DCN). The other SMR projects are monitored by the Innovative Reactors Mission (MRI).

Status of technical exchanges on reactor projects

The table below sets out the framework for technical exchanges between ASN and IRSN and SMR project sponsors as of 1st november 2024:

 
PREPARATORY PHASE

 
Stage 1: Screening phase
 
Stage 2: Project preparatory review
  • HEXANA
     
  • OTRERA
     
  • STELLARIA
  • NEWCLEO
    Cycle of meetings completed
  • NAAREA
    Cycle of meetings completed 
  • THORIZON
    Preparatory review in progress  

 
REGULATORY PHASE

 
Stage 3: Pre-licensing
 
Stage 4: Assessment of the application
  • CALOGENA
    On 31 October 2024, CALOGENA submitted a pre-license application to ASN on a selection of safety topics related to  its CAL30 small modular reactor project
  • JIMMY
    On 3 May 2024, Jimmy transmitted its application file for the creation autorisation of a reactor to supply industrial heat to a Cristal Union Group industrial facility located on the Bazancourt site (51). The ASN has been analysing the admissibility of the application since 6 May 2024.

Dialogue and assessment procedures

In order to optimise preparations for any creation authorisation applications for these various innovative reactor projects, and in order to mobilise resources proportionate to the level of development maturity of each project, a four-phase framework of incremental technical exchanges was set up.

 

In 2023, two SMR project developers also initiated technical discussions with ASN and IRSN in 2023 on projects to develop fabrication plants for their fuel:

  • JIMMY, concerning a project for a TRISO fuel fabrication plant;
  • NEWCLEO, concerning a project for a MOX fuel fabrication plant for a lead cooled fast neutron reactors (RNR).

ASN Report on the State of Nuclear Safety and Radiation Protection in France in 2023

On May 16, ASN presented its Report on the State of Nuclear Safety and Radiation Protection in France in 2023 to the parliamentarians of the Parliamentary Office for the Evaluation of Scientific and Technical Choices (OPECST). On this occasion, ASN presented the subjects on which it was being particularly vigilant with regard to the new nuclear ambitions.

Bilateral meeting with the Indian safety regulator in Mumbai

An ASN delegation, led by its Chairman Bernard Doroszczuk, travelled to Mumbai on 5 March 2024 to meet its Indian counterpart, the Atomic Energy Regulatory Board (AERB) and its Chairman Shri Dinesh Kumar Shukla. This meeting was organised as part of the cooperation agreement that has linked the two safety regulators for nearly 25 years now.
