1 Historical recall
► First French 900 MW and 1300 MW were manufactured under
Westinghouse licence
Design based on ASME III Code Construction based EDF specifications Issuing of the 1974 Order on Main Primary Systems • Safety margins defined so as to be globally compatible with ASME III provisions Technical specifications issued with adaptations and FRA + EDF approval needed
Nuclear Island Components Materials Examination methods Welding Fabrication

1 Why a construction code ?
► To take into account :
Pressure risks Safety concerns
► For a economical interest ► To integrate feed-back experience
Construction code and associated standards (European, ASTM, national standards ) Regulatory requirements Equipment specification

Organizations
► ZU 400: service instruction ► ZU 500: identification of equipment items ► ZU 600: equipment items and assemblies ► ZU 700: materials ► ZU 800: small components
► In 1978
30 nuclear plants in operation or under construction
Practices well established and technical performances known
Decision to write the rules corresponding to these practices
►
General approach
Three barriers • • • Fuel enveloppe Integrity of the cooling system containment
