2.Approach for specifying Equipment

X Global Safety Approach

  • Careful selection of Materials

  • Optimized System and Equipment design

  • Low probability of Defect

  • Careful Non-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 be

considered (Finland).

X Classification 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
