Spoiler warning! This article contains plot details about events that occur later in the game.
Nuclear Plant Zeta is one of three nuclear plants in the Tandor Region. It is accessible by travelling north of the Hazard Zone.
The second nuclear plant in West Tandor. It is located to the northeast of Vinoville Town.
Harsh radioactivity by the nuclear fallout from Zeta has made the surrounding environment teeming with Nuclear Pokémon.
This event is part of the main storyline and cannot be skipped.
After receiving orders from Kellyn to subdue CURIE and Urayne, you and Theo are sent to Nuclear Plant Zeta. You will face off against many Nuclear Hordes with Theo whilst chasing down an unknown Pokémon.
Upon entering a small gap in the trees, you find a group of Hazma and discover that they have the ability to nullify the radioactivity in the air. You should catch at least one of them and then talk to Theo to leave the area.
Once in the power plant, you must find a way to go deeper into the plant. Finding a note, it will tell you that the combination to turn on the power is to pull the green, red, then blue levers before disengaging the main lever.
Before you can enter the North sector, you need to restore power to the West, East, and South sectors of the power plant. The East sector has the Power Cell, which is required to proceed further into the plant. Obtaining the Power Cell will allow you to use Strength as a function of your Hazard Suit, without needing a Pokémon that knows Strength.
Once in the deeper part of the plant, you have five minutes to reach CURIE and Urayne. Should you fail to reach them in that time, the Hazard Suit's emergency protocol will evacuate you back to the healing machine in the southern sector, and you will have 10 minutes to reach CURIE and Urayne the next time you enter the northern sector.

Attempting to retry the northern sector after time runs out will result in your suit immediately returning you to the healing machine as you enter. However, re-entering the northern sector afterwards will allow you to proceed as normal. Click here for more info on known bugs.
