CANDLE fusion power system

The CANDLE fusion power system is a generator located inside the Hidden Valley bunker that supplies power to the Brotherhood of Steel inside of it.

During the quest Still in the Dark, you are asked to retrieve parts from Vault 22 to repair the generator.

Background
While the CANDLE power system was exceeded by many other current designs, it will supply the Hidden Valley bunker systems with power for an estimated 752 years.

Information on the CANDLE can be found on Brother Hood of Steel terminals after doing the virus part of the still in the dark quest.
