12 March 2026

CLEARSY is assisting the CEA Marcoule in modernising the control system for the Basic Nuclear Installation (INB): Multipurpose Intermediate Storage Facility (EIP).

The EIP, located at the Marcoule centre, is a facility dedicated to the recovery, conditioning, storage and monitoring of radioactive nuclear waste prior to its final disposal.

To meet the high demands of this strategic market, CLEARSY has partnered with the French company D3E.

CLEARSY is an engineering firm specialising in critical control systems and complements D3E, a specialist in nuclear electricity and automation.

This Functional In-Depth Study (EAF) focuses on classified nuclear facilities, which are subject to the highest levels of safety and radiation protection requirements.
