PMUC standard compliance: Absolute purity and prevention of stress corrosion cracking
In the nuclear power industry, material integrity is paramount, and there is no room for chemical compromise. Petroseal is proud to offer products fully compliant with the strict PMUC standard, which translates to Products and Materials Usable in Nuclear Power Plants. To meet this rigorous specification, Petroseal developed a highly specialized, ultra-pure nuclear sealing compound engineered to adhere to the draconian chemical restrictions set by nuclear operators.
By drastically limiting halogen (chlorine, fluorine) and sulfur content to trace levels, this proprietary compound eliminates the risk of Stress Corrosion Cracking (SCC) in sensitive stainless steel and nickel-base alloys. Adhering to the PMUC standard is a fundamental guarantee that our materials will never induce chemical degradation in safety-critical systems.
Mitigating nuclear risks with radiation-resistant solutions
Operating within the nuclear island, whether in the primary or secondary cooling circuits, requires auxiliary materials that can withstand extreme thermal profiles and intense ionizing radiation. Standard industrial sealants fail under these conditions due to radiolysis, which causes material breakdown and subsequent system contamination.
Petroseal’s specialized nuclear compounds are specifically formulated to maintain their mechanical properties, elasticity, and sealing performance under continuous radiation exposure. By deploying these advanced, pre-qualified materials, we help operators safeguard the structural integrity of their systems, prevent hazardous fluid leaks, and maintain full compliance with international nuclear safety authorities and rigorous QA standards.

Emergency leak sealing: Maximizing safety
When a steam or fluid leak occurs in a nuclear power plant, a rapid and flawless response is vital to prevent an unplanned reactor shutdown or a forced outage. Petroseal offers specialized, rapid-response online emergency leak sealing services tailored to hot-work and radioactive environments.
Our nuclear-qualified technicians are trained to execute precise interventions under strict protocols, minimizing radiation exposure times for personnel while halting the leak. Using our PMUC-compliant specialized compound injected into custom-engineered enclosures, our team restores absolute containment under live operating pressure and temperature. This allows nuclear operators to maintain grid stability, avoid multimillion-dollar daily losses from unscheduled shutdowns, and defer permanent repairs to scheduled maintenance outages.
