The SARNET network (Severe Accident NETwork of excellence) was co-funded by EC from 2004 to 2013 in FP6-FP7 and then integrated in NUGENIA.

The main network activities are continuing in the NUGENIA Technical Area N°2; one of the three pillars of SNETP Association.

IRSN coordinated SARNET/NUGENIA-TA2 until CIEMAT took over in Dec. 2018.
