4 Principles for Code selectionXPrinciples applied as a function of safety classification: Safety Report of the Owner is the baseXNeeds High level of Safety High availability factor during 60 years Reasonable equipment and maintenance costs Low radiation exposure of workers Standardization to benefit from experienceXIndustrial context Equipment requirements from Contractor Engineering departments Consideration of Suppliers experience: market opening EvolutionaryPressurized Water Reactorfirst developed in a French-German context. Today ready for US and deploymentanywhere in the Code for implementation in EPR asme Semina in RSA r October 7th, for specifying EquipmentXGlobal Safety Approach Carefulselection of Materials Optimized System and Equipment design Low probability of Defect CarefulNon-Destructive Examinations Implementation of QA System (Regulation RD 0034 in RSA) When needed (regulations), measures allowing a "break preclusion concept" to be used When needed (regulations), severe accidental conditions to beconsidered (Finland).

5 XClassification of Equipment As a function of Safety class (SC1, SC2, SC3) As a function of Nuclear Pressure Equipment Regulations( N1, N2, N3 in the context of the French Regulation)As a result, equipment are classified in "Quality Classes" Q1, Q2, Q3 asme Code for implementation in EPR asme Semina in RSA r October 7th, 2008882.
