Pressurizer Heater Repair/Replacement

Leader in U.S. for stuck or damaged heater removal

With more than four decades of emergent repair experience, Framatome can safely and effectively replace or repair your damaged pressurizer heaters — and protect the integrity of your plant.

Utilities seek to mitigate their schedule and risk associated with failed heater damage by implementing contingency plans to address long-lead tasks. These plans include engineering, hardware, and tooling. A proactive approach maintains outage predictability and addresses TB-11-8 recommendations for removal and replacement of non-functioning pressurizer heaters. We offer an “a la carte” approach to contingency planning and implementation for customers based on risk and cost.
