Status of technical exchanges on reactor projects

The table below sets out the framework for technical exchanges between ASNR and SMR project sponsors as of 1st january 2025 :

 
PREPARATORY PHASE

 
Stage 1: Screening phase
 
Stage 2: Project preparatory review
  • HEXANA
     
  • STELLARIA
     
  • BLUE CAPSULE
  • NEWCLEO
    Preparatory review completed
  • NAAREA
    Preparatory review completed
  • THORIZON
    Preparatory review in progress  
  • OTRERA
    Awaiting 1st preparatory review meeting

 
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 ASNR has completed its analysis of the admissibility of the file. The follow-up to this analysis is currently being examined by the MSNR.

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.

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.
