Created at the same time as Electricité de France, DTG was part of the Hydropower Plant Department
in charge of managing the operation, maintenance and modernization of the main hydroelectric shemes of EDF.
Over the following decades, DTG adapted to the evolution of the plants in operation by developing new techniques
to guarantee the safety, performance and optimization of nuclear, thermal and hydropower production.
Today, DTG, with over 60 years of experience, provides its know-how, expertise and assessment
skills in the field of measurement to the EDF Group's power plants in France and in its subsidiaries,
as well as to numerous French and foreign customers.
About FAC
| The Flow Accelerated Corrosion (FAC) of carbon steels is a form of corrosion that is accelerated by a flow of water or wet steam. It is responsible for numerous degradations on steam / water circuits of fossil and nuclear power plants (NPPs). FAC causes wall thinning on the inside surface of components and can lead to leaks or ruptures if wear is not detected in time. |
Due to the stakes of personnel safety and plant availability associated to the FAC phenomenon, EDF has developed
a software called BRT-CICERO™ for the surveillance of the secondary piping system of its Pressurized Water
Reactors (PWRs). The software enables the operator to calculate the wear rates taking into account all the influencing parameters such as : pipe isometrics, chromium content of the steel, chemical conditioning and operating parameters of the secondary circuit (temperature, pressure, etc.).
