How long does it take for a VVER-440 nuclear reactor to switch from the external grid to its self produced power after first starting up?

I am wondering both how long the time period is in which a VVER-440 uses the external power grid for electricity after the reactors first start, and how long the then initiated process takes; from start to finish when the reactor is finally reliant on the electricity it itself produces.
