Nuclear Power Plants

Meet severe environmental conditions

For more than 50 years, Photonis has supplied proven and high-quality detectors, meeting the most stringent and severe environmental conditions for nuclear instrumentation of more than 300 I&C systems in France and abroad. Photonis provides critical components to I&C systems with ex-core (2) neutron detectors for source range (SR), intermediate range (IR) and power range (PR) but also with in-core or in-vessel (1) neutron detectors.

The Nuclear Instrumentation workforce reports to a Quality Management Program that uses both training and independent inspections. This Quality Management program guarantees that you always get safety class components for your systems. Product and related quality documentation are delivered according to your nuclear manufacturing standards, such as IAEA50-C-G / KTA1401, RCCE (EDF rules), ASME NQA-1, HAF604. Quality management and Safety culture are the core of Photonis Nuclear Instrumentation.
