Our FAQs

The design of a custom-built nuclear vessel must comply with the strict criteria laid down by international and national standards such as RCCM (Règlement de Construction des Chaudières Électro-nucléaires), NF EN 13445 and ESPN (Équipements sous Pression Nucléaires). These standards ensure that materials, design, manufacture and testing are adapted to the demanding operating conditions of nuclear power plants. It is crucial that manufacturers have a thorough understanding of CODAP (Code de construction des appareils à pression non soumis à la flamme), as well as international standards such as NF EN 13445 for non-nuclear pressure vessels and NF EN 14015 for the storage of flammable liquids.

For DUS (Diesel Ultime Secours) / Diesel tanks required in the nuclear sector, our manufacturing process follows rigorous quality and safety standards. We use exhaustive quality control procedures at every stage of manufacturing, from material selection to final testing. In addition, all our vessels and components, such as filters and balloons, undergo a series of non-destructive tests and certified inspections in line with ESPN guidelines and other relevant regulations to ensure the integrity and performance of this equipment in nuclear environments.

The creation of effluent tanks in a nuclear context must take into account several essential factors to ensure safety and performance. First and foremost, the tank must be designed to resist corrosion and temperature, depending on the specificities of the effluent being treated. Construction codes such as CODAP, NF EN 13445 and NF EN 14015 are key references when designing to guarantee the mechanical strength and integrity of the vessel under various operating conditions. In addition, suitable filtration systems are essential to maintain effluent purity. Finally, all custom-made effluent tanks must be manufactured and tested in compliance with ESPN requirements to guarantee their operational safety within nuclear facilities.
