Currently, qualification tests have been completed to confirm the compliance of the valves with the requirements of K3 RCC-E.
The test results are positive.
The area of application of the valves is controlling the working medium (air) flow in various pneumatic systems and equipment operated at nuclear power plants.
Qualification of valves in accordance with K3, K2, K1 according to RCC-E (French rules for the design and construction of electrical components of nuclear islands).
RCC-E primarily relates to equipment or software, the failure of which may affect the safety of people or nuclear safety of the power plant.
Ki - qualification procedure category
