This paper presents the COMPROMIS code developed by Electricite de France (EDF) to optimize the maintenance of PWR steam generator (SG) tube bundles. This model, based on probabilistic fracture mechanics, quantifies the impact of in-service inspections and maintenance actions on the risk of failure of an SG tube, with allowance as random variable for all the relevant parameters (distribution of crack sizes, detection and sizing capability, crack initiation and propagation, critical sizes, leak before break risk). The code is SG-specific and is designed to allow realtime evaluation based on manufacturing and inspection data banks.
