Vault-Tec super-reactor

The Vault-Tec super reactor is a craftable and scrap-able settlement object in the Fallout 4 add-on Vault-Tec Workshop.

Scrap-able
You can find pieces of a super-reactor in the main cavern in Vault 88. They are scrap-able and non-usable.

Charactereristics
The Vault-Tec super reactor is a generator that produces 500 power to settlements. It greatly surpasses the previous highest generator, the fusion generator, as the greatest source of energy available. It is virtually silent as well; these advantages come at a cost, however. The reactor takes up a large amount of space and requires many parts to build.
