Pressurizer Heater Repair & Replacement

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

Pressurizer Heater Repair/Replacement

With more than four decades of emergent repair experience, AREVA 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. AREVA offers an “a la carte” approach to contingency planning and implementation for customers based on risk and cost.
