VAPL-84 Power Station

The  is located north of the RobCo Facility and southeast of Evergreen Mills.

A fenced-in power station with a tractor trailer next to it. The tractor trailer contains various ammunition chests and miscellaneous items. 1 Mini Nuke is the significant item of interest. It's also possible to find Stealth Boys, missiles, and assorted custom weapon parts in and around the boxes.

There seems to be a Scavenger post near to the station next to the burning barrel. The barrel is a spot which will spawn various types of NPC encounters upon entering the boundaries of the spawn zone, the scavenger encounter simply being the most common, or perhaps simply the first default iteration of the encounter routine. See Fallout 3 random encounters.

There is also a group of respawning raiders here, but they usually fight with (and are killed by) a Yao Guai in the vicinity.

-Go straight north from the RobCo Facility until you come upon some power lines. -Turn Left and folow the powerlines and you will find the station.
