Current nuke recipe is not fun - requre only 2 machines (compressor and generator) and 4 uran to be created.
This allow anyone to undone days of gameplay in 10-30 minutes, with xray - 5-10 minutes.
Since machines not private, griefer may use machines already on map for this.
Suggestion is simple, use "Re-Enriched Uranium Cell" as component of nuke.
Enrichment process takes long time, require reactor and full set of machines to craft everything, most users dont have any enriched cells to steal and craft into, this factors will make griefing with nukes much more harder and time consuming, ever with xray harvesting everything and crafting reactor will take hours, enrichment also will take hours.
Currently only option is disable nukes at all, or drop explosion power, in both cases "legit" usage of nuke is crippled.
Complete suggestion is:
