Corrosion at thermal power plants poses safety hazards that may be fatal if a worker is exposed to hot steam gas ash or radioactive materials from a leaky component or welding failure. In addition to driving up maintenance costs if corrosion prevents a plant from starting after scheduled maintenance the operators may face non-delivery fees.
