When the Nether Reactor is built and the core activated, it generates a room of obsidian (7x17x17)with some openings, around the reactor. The reactor itself will turn into a new block called "Glowing Obsidian" resembling netherrack, and it will start spawning various items and blocks, such as gold, melon seeds, paintings, glowstone dust, doors, mushrooms, bones, cactus's, arrows, feathers, bowls, surgarcane etc, as well as Zombie Pigmen. The Zombie Pigman texture is different however.

NOTE: The Reactor does function in Creative Mode; this is intended.

Zombie Pigmen do not spawn in peaceful mode, but you still get the items.

This lasts around 45 seconds. After it is over. There will be a massive obsidian structure with multiple floors.
