We are very proud to announce that the CEA has chosen the ONET Technologies and EGIS Industries consortium to oversee the design and implementation of the nuclear waste recovery and conditioning project in the northern zone of the Marcoule site. The project, scheduled to last 10 years, will recover and condition historic waste packages from the Marcoule site, and store them in a new interim storage facility before transfer to ANDRA for final disposal.

What is the RCD-ZN Project?  

The CEA has entrusted GMEC Onet Technologies - EGIS with the project management of the installations required for the RCD ZN Phase 1 project.

This project for the recovery and conditioning of stored waste from the northern zone of the CEA Marcoule site consists of building 3 facilities:

• a storage area for waste packages extracted from pits: Entreposage EI-ZN
• and two waste recovery and conditioning facilities, one for high-level waste (USR Fosse HA) and the second for medium-level waste ( USR Fosse STEL).

A project combining technical challenges with respect for costs, deadlines and safety, and scheduled to run from 2021 to 2031.

How did we respond to the customer's request?

Onet Technologies offered the customer a complete package, combining technical expertise with all the professional skills required for the project.

 The tasks entrusted to GME ONET Technologies EGIS are divided into several phases:

Design studies (APS-APD missions) for buildings, and preparation of associated safety reports and notes.

The GMEC assists the CEA with the awarding of works contracts (DCE - ACT), verifies execution studies (VISA), and provides site management (OPC) and works supervision (DET). Following this approach, particular attention is also paid to monitoring the testing of the various work packages in the factory and on site (Mission ESS), as well as the acceptance of contracts (Mission AOR).

The final phase of construction will involve the commissioning of the buildings and their assets (MSI and MSA missions), followed by feedback (REX mission) and reversibility (REV mission).

Why did CEA choose GMEC Onet Technologies and Egis Industries?

In the past, the two companies have already worked together on large-scale projects, demonstrating their skills in very distinct areas: Egis Industries for civil engineering and Onet Technologies for the design and supervision of specialized projects in the decommissioning sector.

Acting as partners on this project, Onet Technologies and Egis Industries once again confirm their commitment by working together on the design and construction of new facilities.

The start has been made for the study phase, which will already involve twenty people over the next two years.
