Criticality Research and Neutronics Development Laboratory (LNC) / Reactor Physics Research and Safety Assessment Laboratory (LNR)


The Criticality Research and Neutronics Development Laboratory (LNC) and the Reactor Physics Research and Safety Assessment Laboratory (LNR) arise from the Study, Research, Codes Development and Validation Laboratory (LERD). LNC is managed by Isabelle Duhamel and LNR, managed by Sophie Pignet.



Missions

 

The role of the LNC and of the LNR is to:

  • develop, validate and qualify codes, calculation templates and associated tools required to assess the risks of criticality present in nuclear facilities and the modes of transport and to ensure the coordination of their maintenance;
  • design and monitor experimental programs needed to improve the qualification of the calculation templates used at the IRSN to assess the risk of criticality;
  • carry out applied studies concerning the assessment and prevention of criticality risks.


Furthermore, the laboratories are the reference for the technical fields of applied statistics and neutronics.
