Ruthenium 106 in the ambient air in France: no risk identified for the population
As part of its duty of radioactivity monitoring nationwide, the French Institute for Radiation Protection and Nuclear Safety (IRSN) measured the presence of ruthenium 106 in south-eastern France, between the end of September and the beginning of October 2017, albeit at very low levels, representing a few microbecquerels per cubic metre (µBq/m3). This detection led to the distribution by IRSN of several information notices on its website.

Flamanville EPR reactor: ASN issues its opinion
On 10th October 2017, ASN issued its opinion on the anomaly in the steel used for the Flamanville EPR reactor pressure vessel lower head and closure head. ASN considers that this anomaly is not such as to compromise the commissioning of the reactor pressure vessel, provided that specific checks are carried out during operation of the installation. As the feasibility of these checks cannot at present be confirmed for the closure head, ASN considers that the current closure head cannot be used beyond 2024.
