Reactor Coolant Port

The Reactor Coolant Port provides an interface for pumping coolant into a multi-block reactor, and for pumping superheated steam out. Putting one or more of these on a reactor will change it from producing energy to producing steam. This is called Active Cooling Mode.

A Coolant Port is not required to complete a reactor. An actively cooled reactor requires at least two Coolant Ports: one each for input and output. Coolant Ports do not have a limit to their flow rate.

Any number of Coolant Ports may be placed in a reactor. They must be on vertical faces, inside the outer frame.

Active Cooling Mode
When one or more Coolant Ports are present, the reactor will be placed into active cooling mode.

An actively cooled reactor will not generate any RF energy on its own. Water must be pumped in, and the resulting steam pumped out. The steam can be used in a Steam Dynamo or in the multiblock turbine.

While this is more complex, it provides a way to increase the efficiency and output of a reactor without expanding the reactor itself.

Inputs and Outputs
Coolant Ports come in two flavours, Inlet and Outlet. Inlet ports can be recognized by light blue, inward-facing arrows. Outlet ports have bright red, outward-facing arrows. To switch between these modes, simply right-click the Coolant Port with a wrench or an empty hand.

An inlet port provides access to the reactor's coolant fluid tank (water), and an outlet port provides access to its hot-fluid tank (steam).

When in outlet mode, the port will automatically attempt to pump fluids into compatible adjacent blocks or pipes.
