Report on the results of stress tests
The European Nuclear Safety Regulators Group (ENSREG) and the European Commission have adopted, on April 26 2012, the report on the results of the stress tests on European nuclear power plants.
This report responds to the request from the European Council on 25 march 2011 asking for the launch of stress tests on the European nuclear power plants to take account of the first lessons learned from the Fukushima accident.

I&C architecture of the Flamanville 3 EPR
ASN considers that the changes EDF has made to the instrumentation and control (I&C) architecture of the Flamanville 3 EPR are satisfactory and enable it to lift the reservations it expressed in October 2009. This position is based on the analysis by its technical support organisation, IRSN, and the opinion of the Advisory Committee for nuclear reactors.

Traces of iodine-131 detected again in several European countries
ASN has been informed by its European counterparts of new cases of iodine-131 being detected in several countries in northern and eastern Europe. IRSN, the French Institute for Radiological Protection and Nuclear Safety, responded to the presence of this isotope in atmospheric aerosols by stepping up the frequency of its environmental radioactivity measurements to detect whether the phenomenon also affected France.

ATMEA1 reactor project
Following a review process lasting 18 months, ASN issues a positive opinion on the safety options for the ATMEA1 reactor project.
With the technical support of the Institute for Radiation Protection and Nuclear Safety (IRSN), ASN reviewed the safety options for the ATMEA1 pressurised water reactor. This medium-power reactor (1100 MWe) is designed by the ATMEA company, an AREVA and Mitsubishi Heavy Industries (MHI) joint venture.

Pipe nonconformity in two Cattenom NPP fuel storage pools
On 18th January 2012, EDF notified ASN that the absence of a "siphon breaker" orifice on the fuel storage pools of reactors 2 and 3 had been detected during an internal inspection.
In every reactor, a pool is provided for the storage of fuel assemblies pending their use in the reactor core or pending disposal. The fuel assemblies are kept under water and permanently cooled. A significant drop in the water level would lead to an exposure of the fuel assemblies and to their damage. Alarms indicate any drop in this level, with the necessary action being triggered.
