Official description:

Counter-Terrorists: A silent alarm has been tripped by the guard shack at the MAC Nuclear Power Plant. We will enter from the back side of the plant and secure the area.

Terrorists: Our target is a recently decommissioned nuclear power plant that still contains spent fuel rods. Security is at an all time low since the plant's closure and the fuel rods are scheduled for removal next week. Plant the C4 in the fuel rod room, or the room directly above it to destroy the cooling pools and melt down the reactor.
