It was caused due to a lack of security from Sam's part as he didn't send reinforcements to the power plant, so there was only 3 guards there when Caine attacked the power plant. As the name says, the battle was fought outside the Nuclear Power plant. This battle resulted in the power plant being destroyed because of all the hits it takes during the battle. This was the first-ever battle where Orc really showed his strength, being the one who is responsible for making a hole in the wall of the Power plant to make it possible for Sam and the other defenders to defend the plant its self, and the guards that are already in the plant.
The main soldiers were as following (there's some uncertainty about some of the information):
This group of kids, led by Sam Temple, succeeded in winning the battle and defended the plant. Despite this, the power was still shut off.
This group of kids, led by Caine, failed and lost the battle. They managed to steal a fuel rod from the plant to give to the Gaiaphage.
Events of the Battle for The Nuclear Power PlantEdit
Before the attack on the power plant, Cain had been treated by Diana as described more closer on the Hunger page. Caine immediately starts to plan his revenge on Sam after the painful defeat in Perdido Beach, and soon releases the weak point of Sam and his friends: The power plant. However, it's not Caine's only reason for attacking the plant. He has been affected by the Gaiaphage, and now the Gaiaphage demand food in the form of fuel rods from the plant. He orders Diana, Drake and a few others to attack the Power plant. In the meantime, Sam Temple and his people have been distracted because of the events out on the farm fields, and therefore, Sam only sends out three guards to the power plant. When Drake and Cain arrive at the power plant, they immediately shoot one of the guards, the two remaining guards surrender, even though one of them had a machine gun which would end it short off with Caine and his people.
Immediately after the news of the events on the power plant reaches Sam, he orders all available soldiers to immediately attack the power plant in defense. Sam orders Orc to throw a car into the wall of the power plant, crushing the wall so that they can invade it and attack Caine and the others inside. However, it doesn't help very much. Caine escapes with the fuel rods, while Sam surrenders and is being tortured by Drake on the condition that he should not harm anyone else. However, Astrid and some others arrange an ambush on Drake, and rescue Sam from the power plant.
After the attacks, all the power in the FAYZ was shut down, except from on a small island out on the sea. The fuel rods were damaged during the final battle in the mineshaft, however, the fuel elements inside the fuel rods were spread inside the mine, making it dangerous to walk there. In the book, the radiation from the fuel elements is described as "green and dangerous" light.
