Safety of the installations: prevention of industrial risks


Producing and supplying energy is a key activity, both from an economic and social point of view. Maintaining the integrity and proper functioning of the industrial as well as the administrative sites of EDF Luminus is thus a necessity. An industrial accident (a gas pipe rupture, for example) could have significant consequences on the health of employees, neighbours and the environment.


NB: EDF Luminus owns 10.2% of four Belgian nuclear power plants, but has no responsibility, direct or indirect, in their operation (see royal decrees of December 19, 2000).


EDF Luminus aims to avoid any serious damage, whether to people or to the environment.

In addition to the permits granted by the authorities, every new site undergoes a systematic industrial risk analysis: during the design phase, when it is put in operation, subsequently every five years, and whenever any modifications are made on all or parts of the installation. The evolution of risks throughout the lifetime of the site must be controlled, both in terms of the installation itself and the operational and maintenance processes.


Residual risks are classified based on their potential consequences and their likelihood to occur, integrating in particular:

  • the information provided by the builder;
  • the analysis of incidents or near-incidents observed in situ, for the entire industry;
  • additional risk studies carried out by multidisciplinary EDF Luminus teams supported by external experts;
  • shared experiences of the sector and the authorities

Monthly reporting on the progress of the actions implemented aims at reducing the risks. The reporting method used helps to secure ISO 14001 and OHSAS 18001 certification.


An innovative system for detecting oil leaks at Ampsin

During the electrical renovation of the Ampsin hydroelectric plant, the Asset Management team developed an oil-sensing system to be installed in the plant’s drainage sumps, in order to avoid any discharge of oil into the Meuse. The prototype was installed by EDF Luminus subsidiary ATS.


The drainage sumps in a hydroelectric plant are shafts dug out to collect water draining from the turbines, to avoid the plant being flooded. The drained water is released downstream from the plant, in automated pumpsystems. This water could be polluted by oil leakage, for example due to a deterioration in the pipe seals.


The new system detects the presence of oil in the sump itself. It automatically stops the pump, sets off an alarm, and starts a pump in another sump. This avoids oil leakage into the Meuse and facilitates human interactions.


After a test period, an implementation plan for this new system will be set up based on the configuration of the various EDF Luminus hydroelectric plants.


EDF Luminus must report to the competent authorities about incidents relating to its installations. All incidents that may cause environmental damage, however small, must be reported.


In 2017, no environmental incident had to be reported to the authorities. To date (Sunday 31 December 2017), EDF Luminus has not yet issued a statement about a serious incident.
