After this meeting, ASN held its annual steering committee meeting with the USNuclear Regulatory Commission(NRC), its American counterpart. Among the issues discussed was the problem of carbon segregation, which affects a number of pressurized equipment in French facilities. In a more general way, the NRC explained the manner in which it oversees the operating reactors as well as the reactors in construction in the United States with the respective Reactor Oversight Process (ROP2) and Construction Reactor Oversight Process (cROP3). Both authorities discussed several cooperation topics such as the decommissioning of nuclear facilities and the oversight of nuclear installations’ environmental impact. They also confirmed their determination to carry on with their foreign assignees’ program, which helps reinforcing mutual understanding and sharing respective knowledge and preoccupations.

The next bilateral meeting between ASN and the NRC is scheduled for June 2018 in Paris.
