Computational Fluid Dynamics (CFD) in Nuclear Reactor Safety (NRS)


Recognising the growing and widespread use of CFD in many branches of engineering, a CNSI action plan was drawn up in 2001 which resulted in the creation of three writing groups (WGs) with mandates to perform the following tasks:

  1. WG1: provide a set of best practice guidelines for the applications of CFD to NRS problems;
  2. WG2 (click here to access): evaluate existing CFD assessment bases and identify gaps that need to be filled;
  3. WG3: summarise the state-of-the-art of extended application of CFD codes to two-phase NRS problems.
