eddylab's portfolio includes sensors that can be qualified according to RCC-E or IEEE standards for use inside or outside the containment. eddylab follows a holistic approach, providing the complete measurement chain up to the control room outside the containment. The design of each component is tailored for robustness and durability. Inside the containment, all products are consistently designed to be inorganic and hermetically sealed. The nuclear product range of eddylab withstands all environmental challenges regarding thermal and seismic stress as well as radiation exposure. For power plant applications, eddylab offers a complete solution: from sensors and cabling to electronics housed in a dedicated control cabinet.

eddylab's system solution
In addition to development, eddylab also offers product qualifications in accordance with the RCC-E or IEEE standard, thereby ensuring that the measurement systems function reliably even under extreme operating conditions. The aim of the qualification is to prove suitability for the specific safety-related application. The qualification includes extensive testing under realistic operating and accident scenarios, including temperature, radiation, vibration, humidity, EMC, seismic, and LOCA tests. This ensures the long-term usability and safety of the products. To ensure full qualification, eddylab collaborates with a wide range of renowned testing laboratories to carry out all necessary tests.
