CERAP Prevention

What CERAP Prevention does

CERAP Prevention, headquartered in Cherbourg-en-Cotentin, France, and founded in 1988, provides specialist nuclear radiation protection and radiological risk-management services to operators of nuclear power plants, research facilities, naval propulsion programs, and fuel-cycle installations. Its service portfolio spans radiation protection studies, operational radiation protection (with embedded on-site teams), HSE risk prevention, calibration and periodic verification of radiological instrumentation, operational maintenance, delegated management of radiation-protection equipment, waste characterization, delegated laboratory operation, nuclear measurement studies and engineering (including proprietary underwater spectrometry tooling), ventilation-system qualification, and radiological risk training delivered through its SEFC Formation subsidiary. The business is organized as a French société anonyme operating within the CERAP Group, which itself sits inside the diversified ALTRAD industrial conglomerate.

The company serves a concentrated base of French and international nuclear customers, including EDF (the national utility), CEA Cadarache, Orano, Framatome, Naval Group, Westinghouse Electric Company, Laborelec (Engie), and CERN, with international delivery via subsidiaries NUSAM (UAE), CERAP UK & Nordics, and CERAP Switzerland, supported by calibration arm ATRON Metrology and engineering arm Advance Engineering. Revenue is generated through long-term service contracts, multi-year framework agreements, equipment-management mandates, accredited calibration work, and fee-based training programs. Switching costs are high because of regulatory qualifications, on-site integration, and the depth of customer-specific operational know-how accumulated across decades of embedded service delivery.
