Circé Engineering Goes Nuclear

Circé Engineering are experts in complex and critical systems for the Aeronautical, Nuclear, and Transport Industries. Circé has recently performed an Analysis for a French Nuclear Installation for the CEA (French Nuclear Ministry).

Confronted with problems of significant availability of its ventilation and electrical distribution systems, Circé Engineering has modelled all the failure modes and their consequences, as well as the scenarios that were causing the appearances of critical events, within the ITEM ToolKit™ FMECA module.

Around 1,000 failure modes and 200 events have been created for this analysis.

ITEM ToolKit's fault tree functionalities have also allowed a clear identification of the functional state points by:

Using different colours for every functional sub-group,
Inserting symbols for the main components,
The use of the various maintenance times bringing an accurate modelling of the installation operational state,
A0 printing format facility allowed the visualisation of the full project.
Thereafter, the action plan implemented following this study made it possible to notably improve the availability of the installation, by eliminating the weak points and improving the redundancy.
