Well first of all, there is a requirement to start a nuclear launch, I might be wrong on this one since I haven't played in over half a year but if I remember correctly it's 10 players (out of which 3 must be police jobs), someone correct me if I'm wrong.

You need to acquire a nuke either through crafting using ores, buying it from someone else, crafting via blueprint, etc - After getting the nuclear launch, you simply click on it in your inventory and do "Drop", it will be placed in front of you, after which you simply press E whilst looking at it and clicking "Start nuclear launch".

You need to protect it for 15 minutes (prevent it from being disabled or destroyed), if you succeed in doing so, you will receive an SCU (Super Charged Uranium) which is a very expensive item that is used for crafting various items and weapons (such as the Gluon Gun).
