“EDF Chooses Atos Origin to Deploy Power Generation Monitoring System and Maintain It With Operational Readiness Support”
Paris – October 11, 2007
Process modernization will enhance prevention and management of incidents that could impact power generation French national power utility Electricité de France (EDF) is working with Atos Origin, a leading international IT services company, to extend deployment of its monitoring and diagnosis assistance system to France's entire fleet of 900 MW and 1300 MW nuclear power plants (totaling 54 nuclear reactor units1). The system will enable EDF to detect potential failures before they occur, thereby avoiding unplanned shutdowns and reducing maintenance costs, while extending the plants' operating lives.
EDF has long cooperated with Atos Origin to design a prototype for the future monitoring system and to deploy it on around ten nuclear units, with the goal of preventing failures and ensuring uninterrupted power generation. The primary objective is to improve power grid uptime by enhancing the effectiveness of maintenance operations.
With the solution, EDF engineers and operators will be able to collect data from the sites on demand, giving them a comprehensive overview of the condition of plant equipment via an EDF intranet. Power plant maintenance staff will have an information system that provides a complete picture of equipment conditions thanks to in-depth analysis of plant operating data, enabling them to carry out on-condition maintenance. Enhanced preventive maintenance lowers maintenance costs and maximizes power generation because it is performed prior to the occurrence of failures on the components monitored by the integrated monitoring and diagnosis assistance system (known by its French initials as PSAD).
The PSAD2 system monitors all the equipment that plays a critical role in the availability of a nuclear reactor (unit capability factor). Monitoring is based on the acquisition of acoustic and vibratory signals that indicate trouble-free operation.
Atos Origin is providing the following services:
- Integration of the changes needed to upgrade the data acquisition systems, including replacement of PSAD hardware and software.
- Software upgrades based on feedback from the full-scale operation of the target system prototype.
This first phase will stretch from 2006 to 2009. Deployment of the system across the fleet, including operational readiness support services, is scheduled for 2009 to 2014.
“Atos Origin has nurtured a long-standing relationship of mutual trust with EDF as a supplier of systems for all its nuclear plants,” said Jérôme de Parscau, Managing Director of Atos Origin's Grenoble Service Center. “Our ability to provide long-term support for our customer is a major advantage. For example, we began building the prototype for this monitoring and diagnostic assistance system back in 1990, then installed it on around ten nuclear units, with complete deployment scheduled to be completed in 2014. The experience acquired so far has enabled us to develop proficiency in the related processes and to deepen our understanding of the functional requirements of the nuclear industry, nuclear power plant maintenance systems and data acquisition technologies. We are proud to be able to continue working closely with EDF as their nuclear power plant fleet evolves.”
1/ A nuclear unit comprises a nuclear reactor and the associated electricity generation system, primarily a turbine and generator. A nuclear power plant generally comprises several such units.
2/ PSAD technical specifications:
- Operator workstations running on Linux.
- Oracle database (Ada and C++).
- Data acquisition for the monitoring systems uses VXI signal processing boards, with VX Work.
The EDF Group, one of the leaders in the energy market in Europe, is an energy specialist that is active in all the businesses of electricity: production, transport, distribution, energy supply and trading. The Group is the leading electricity producer in Europe. In France, it has mainly nuclear and hydraulic production facilities where 95% of the electricity output involves no CO2 emissions. EDF operates 1,246,000 km of low and medium-voltage overhead and underground electricity lines and around 100,000 km of high and very high voltage networks. The Group is involved in supplying energy and services to more than 40 million customers around the world, including more than 28 million in France. The Group generated consolidated sales of more than €59 billion in 2006, of which 42 % in Europe outside France, while net income from ordinary operations stood at €4.2 billion. EDF is listed on the Paris Stock Exchange and is a member of the CAC 40 index.
In less than 20 years, EDF has developed an unrivaled fleet of nuclear power plants, with 58 reactors providing total installed power of 63.1 GW and accounting for more than 85% of EDF's electricity production. This makes France the world's second largest generator of nuclear power, trailing only the United States.
