ASN publishes guides in English regarding the decommissioning and remediation

In France, once a basic nuclear installation (BNI) is definitely shut down, it must go through the decommissioning and remediation process, with the end goal of achieving a predetermined final state in which all the hazardous substances have been removed. Accomplishing these decommissioning operations can often present a technical and project management challenge to licensees.

Reactor 2 of the Penly NPP: a significant safety event rated level 2 on the INES scale

On 18 December 2019, EDF reported a significant safety event relating to defective electrical components which put the backup systems of the Penly NPP reactor 2 out of service. The equipment ensuring the safety of each NPP reactor is supplied with electrical power via two redundant electrical panels (channels A and B). These electrical panels supply power to the motors that actuate the valves and pumps of the backup systems and the reactor instrumentation and control panels.

Generic phase of the fourth periodic safety reviews of the 1300 MWe reactors

On 11 December 2019, ASN issued a position statement on the orientations of the generic phase of the fourth periodic safety review of EDF’s 1300 MWe nuclear reactors. ASN considers that the general objectives set by EDF for this review are acceptable in principle. However, it asks EDF to modify or supplement these general objectives for this safety review, to consider certain baseline requirements for reassessment of the safety of its facilities and to add study topics to its review programme. The requests made by ASN are to a large extent based on those made in 2016 for the fourth periodic safety review of the 900 MWe reactors.

ASN takes stock of the earthquake resistance of the French nuclear power plants

In the wake of the Teil earthquake of 11 November 2019, ASN takes stock of the earthquake resistance of the French nuclear power plants. Earthquakes form part of the natural risks that nuclear facilities must be able to withstand. Seismic protection measures are taken at the installation design stage and reviewed every ten years during the periodic safety reviews to take account of developments in knowledge and changes in regulations.
