Large components at their maximum capacity
By maintaining the major components in optimal working condition, AREVA helps its customers to sustain or increase the performance and safety of their facilities. These services also aim to increase their service life.
Field Report #7: Fleet Safety
Experience shows that very unlikely events occur and that plant operators need efficient systems to safely shutdown their plants and to remain in control in case of an unexpectedly complex sequence of events.
Find out how AREVA is helping utilities demonstrate the safety of their nuclear fleets, while reinforcing public confidence.
Our maintenance solutions for major components aim to protect them from damage, to repair them or to replace them so that they are in optimum working condition at all times. It is also possible to install improved components at the customer's request.
Our services relate to:
- Steam generators
- Reactor vessel caps
- internal vessel equipment
- Pressurizers
- Pipes in the reactor coolant system
- Primary pumps
Large components at their maximum capacity
- Synergies with design/manufacturing units: they enable us to provide a global component replacement service for all phases, from design up to manufacture of new components and to install them in the reactor.
- Trained, qualified teams, constantly learning about the best nuclear techniques in our specialist centers. We also benefit from expertise in the management of large-scale projects. Controlled worksites, thanks to solid international experience. We have performed over forty steam generator replacement operations and around 90 reactor vessel cap replacements around the world.
- Managed sites: we have acquired solid international experience through more than forty steam generator replacement operations and around 90 reactor vessel cap replacements around the world.
- Off-site repairs for certain components (pumps, control rod drive mechanisms, etc.). Carried out in our specialist workshops, the advantage of these operations is that they do not impact unit outages.
A set of high technology tools
We have developed a set of high technology tools suited to component repair and inspection initiatives:
- Robotic carriers and remote control for steam generators.
- In-pipe manipulators for piping (machines traveling within the pipes).
- Operation masts in internal vessel equipment.
- etc.
