U-bend cracking at Doel 2

  • 1. Laborelec, Rhode-St. Genese, Belgium

Description

Two Westinghouse 390 MWe PWR have been in operation since 1975 (units 1 and 2). The accident happened in June 1979, during a re-start of Unit 2. The pressure in the primary loop began suddenly to drop (about 0.2 MPa/min, i.e. 28 psi/min). In the secondary loop, the level of the water increased quickly in SG B and the activity of the blow-down reached the maximum indication. A primary-to-secondary leak in the steam generator was indicated and later estimated at 50 m3/h or 40 metric tons per hour. Examination of the leaking tube is described
