Examples of successful LTO support projects

NRG PALLAS helped Borssele NPP in the Netherlands and Ringhals NPP in Sweden to set up and go through an operating time extension process. IAEA guidance was used as a basis and was performed using NPPs initial ageing management and maintenance approaches. Read more about how both processes led to regulatory approval.
