    Rotating equipment are replaceable is not that much of an issue they operate on regular steam.

    Buildings are reinforced concrete unlikely to be a concern not in a reasonable timeframe unless rebars corrode for some reason.

    Issue would be items operating with water directly in contact with the reactor, so critical piping, heat exchangers and reactor vessels, which I can’t say I am an expert specifically for nuclear plants.

    I imagine the main concern would be the reactor itself as all reat can be replaced.

      Not to argue minutia, as it doesn’t take away from my correct point, but I was speaking specifically of the reactor and it’s housing and the building around it. A reactor when it’s built has a pre-planned age limit to it.

        We can do calculations to evaluate them. If someone creates a fairly accurate or at least conservative stimulation of the reactor and housing, a mechanical engineer should be able to determine if it’s still good for operation or needs replacement. They use ASME code and tables to do life fraction calculations.
