Carbonating in a secondary vessel

[perfection]

If a brewer transfers the green beer after active primary fermentation at an appropriate Plato level to a secondary or conditioning tank where he sets the head pressure and captures the CO2 released by the yeast in their lag phase - is this practice called spunding? Does this meaan that spunding can be carried out in a primary vessel or a secondary tank?

Spunding can be done in either a primary or secondary. It's the process of allowing pressure to build to a set point and venting excess CO2 once that pressure is reached. Unless you're doing it in to free up your primary fermenter, there's no reason to transfer prior to spunding and, unless you do a closed transfer, you're unnecessarily exposing your beer to oxygen and the possibility of contamination.
