Primary water stress corrosion cracking (PWSCC) phenomena affect Alloy 600 base material as well as Alloy 182 / 82 welds. Periodic safety reviews and license renewal processes require assessment of the condition of Alloy zones with respect to PWSCC. Adequate aging management programs (AMP) must be implemented to manage these Alloy 600 issues.


The Alloy 600 and Alloy 182 / 82 Management analyses the risk of PWSCC and optimizes your AMP. AREVA NP can propose solutions for every step of the AMP, in line with the regulatory framework:

  • Evaluation of risks and life prediction
  • In-service inspections
  • Repair, replacement or mitigation strategies.


Your benefits

  • Competencies to assess the condition of your reactor pressure vessel (RPV) alloy 600 zones, predict their evolution, and propose repair solutions
  • Support to help you select the optimized scenario adapted to your constraints
  • Engineering, non-destructive examination (NDE) mitigation, repair and replacement
