Plant Upgrade

Extending the lifespan of nuclear power plants

We make sure power plants continue to operate under optimum safety and performance parameters beyond their designed operational life.

Generally, the designed lifespan of a reactor is around 40 years. After 10 years of operation they begin to deteriorate, mainly due to irradiation, thermal and mechanical loads, and corrosive and abrasive processes. 

Plant life management (PLiM) helps to ensure that the plant continues to operate under optimum safety and performance parameters by repairing and correcting these aging processes. 

Plant Life Extension procedures in various countries across the world follow a relatively similar process, barring minor variations based on regulatory and other requirements.

Typical areas of support:

  • Environmental due diligence assessment
  • Modernisation of systems (e.g. I&C)
  • Process engineering
  • Test preparation and implementation
  • Verification and validation
  • Commissioning
