BOËT STOPSON, Un partenaire du projet DUS

BOËT STOPSON, A partner in the DUS project

The DUS programme, Diesel Ultime Secours, was launched following the Fukushima disaster and is part of the “grand carénage” programme (budget 10 billion euros).

A corporate success story for a major project !

One of the main measures is the installation of a 2.7 MW Diesel Emergency Power Unit (DUS) for each reactor in the French nuclear power plant. In extreme situations, this system must provide the power supply for the safety systems and mainly the cooling systems.

It is in this strategic context that BOËT Stopson was chosen as the supplier to carry out the global acoustic study of the building as well as the supply of the 56 intake and exhaust networks for the generators.

More than 6,000 hours of engineering, including CFD, FEA and acoustic studies and simulations, were used to develop and qualify the systems (earthquake, tornado, shock wave).

More than 60,000 hours of manufacturing were carried out in our workshops to transform more than 780 tonnes of certified and controlled materials for complete traceability.
The manufacturing process includes all the operational phases by qualified personnel as well as the control phases in accordance with the applicable standards, codes and specific customer requirements.

In May 2018, the last chimney left our workshops. It thus concludes the four years during which BOËT has worked for the success of the DUS project.
