I just finished an AoVash challenge and a lucky invulnerability or two let me go on a nuking spree. After checking the morterm to try to count actually how many nukes went off, I discovered two things. Using the angel arm doesn't add an entry for nuking the level in the mortem and it does count as clearing the vaults. The mortem lists 4 visited special levels, 1 completed and there is no way I completed either the CC, City of Skulls or the Lava pits but I did nuke the Vaults to raise the nuke count, so that one must be it. Here is the mortem:
--------------------------------------------------------------
DoomRL (v.0.9.9.3) roguelike post-mortem character dump

Adrian Carmack, level 10 Arch-Vile Blade, nuked the Cyberdemon.

He played for 10 minutes and 57 seconds.
He didn't like it too rough.

Who gave him the ticket to hell, anyway?

-- General ---------------------------------------------------
Before him 1136 brave souls have ventured into Phobos:
955 of those were killed.
16 of those were killed by something unknown.
60 didn't read the thermonuclear bomb manual.
And 29 couldn't handle the stress and committed a stupid suicide.
Some rumours though, say that the Cyberdemon was killed already!
Is he immortal? 76 souls claim to have killed him...
35 sacrificed itself for the good of mankind.
41 killed the bastard and survived.

A nuke went off every regular floor from 18-26, then another in the Vaults. I used the Angel Arm eight times, one encountered nuke and my initial nuke (on floor 23) for a total of 10 nukes, but only the encountered and my initial made it to the mortem. I did get the Fallout platinum, though. I'm assuming nuking the Vaults is bad since it'd make the scavenger diamond a lot easier.
Wait, I found both the Trigun and GCB? Damn, too bad it wasn't an AoMr game...
