Precision sealing
for Nuclear power
Your Primary Circuits Leave No Room for Error
Whether in the primary or secondary circuit, sealing integrity is a critical safety requirement. Equipment operating in radiation-exposed environments faces conditions that accelerate the ageing of conventional elastomers far beyond what is encountered in standard industrial applications. A seal that has not been specifically qualified for nuclear environments can compromise the safety of the entire installation, regardless of its apparent performance under normal operating conditions.

Our Nuclear Sealing Solutions
O-Rings and Rubber-to-Metal Bonded Seals
These sealing solutions are used in heat exchangers and throughout primary and secondary circuit systems. They also contribute to the protection of uranium enrichment processes.
Available in a wide range of elastomer families, including compounds specifically qualified for nuclear applications, they provide reliable sealing across all fixed interfaces, from piping connections to heat exchanger housings.
Inflatable Seals
Inflatable seals provide an effective solution for installations incorporating moving components or large dimensional tolerances between mating parts.
Widely used in the nuclear industry, they ensure sealing integrity for airlock doors and other access points requiring airtight containment. They are also used on reactor pool stop logs, where absolute reliability is essential.
Diaphragms and Bellows
Diaphragms enable pressure transfer between chambers within the installation and can be reinforced with textile or metallic inserts according to operating conditions.
Bellows complement these solutions by protecting moving mechanical components from external contamination and environmental exposure.
Together, these technologies safeguard some of the most critical and exposed elements of nuclear systems while allowing the freedom of movement required for reliable operation.
