Streamlining unit outage time

Men during unit outage at Gravelines 3

Producers of electricity aim to reduce unit outage time to a minimum. AREVA assists them in the organization of this period in order to optimize how this takes place.

The service aims to plan and organize the unfolding of all activities associated with a unit outage in order to reduce the power plant's downtime to a minimum.  This preparatory stage begins 8 to 12 months before the unit outage. 

The programs, designed on a case-by-case basis, take all the aspects of a shutdown into consideration: quality of operations, safety and security, costs.

Our range of products and services is based on international teams of specialists. These teams boast several decades of experience in management of unit outages. Every year our teams take part in more than one hundred unit outages around the world.
