Samaro’s PMUC Articles: Standards and Products for Nuclear Maintenance
Introduction to the PMUC Standard
Safety and reliability are top priorities in the maintenance of nuclear and thermal power plants. This is where PMUC (Produits et Matériaux Utilisés en Centrale Nucléaire) approved products play a crucial role. Instituted by EDF, this standard imposes strict chemical specifications to ensure that the products used pose no risk to sensitive equipment in nuclear power plants. Suppliers, like Samaro, must have each production batch analyzed in approved laboratories to guarantee compliance with this rigorous standard.30
