Nuclear reactor

The nuclear reactor is a room available in Fallout Shelter.

Overview
The nuclear reactor is the Tier II version of power generation. It produces a moderately larger amount of power, although it is significantly more expensive. Like most other rooms, the Nuclear Reactor can be combined into a 3 wide room, increasing production and allowing more workers.

Power generation
To increase the speed at which power is generated, place dwellers with better Strength in this room.

The nuclear reactor room, like other rooms, gains a production and upgrade cost bonus from being connected to another room of the same type and level. The rooms will gain more than x2 production bonus for each connected room. Upgrade costs will be 25% cheaper for a double room and about 33% cheaper when upgrading a triple room vs upgrading 3 single rooms.

Compared to the power generator, the basic power production room, the nuclear reactor generates more power with a slightly longer production time. The nuclear reactor is overall the more efficient of the two, with a better ratio of production time to production quantity than the power generator. The nuclear reactor is also significantly more expensive to build and upgrade than the power generator room, but also has the benefit of vastly increased power storage capacity, four times as much.
