Why are blueprints placed with missing combinator network connections?

Blueprints made with RealisticReactors before version 3.0.0 need to be updated due to fixes in the reactor's combinator network interface. When using blueprints or copy/paste in the game editor, the combinator connections aren't placed and need to be added manually, probably because not all events are sent in the editor.

How to operate a reactor?

To start a nuclear reactor insert fuel cells and send the Start Control Signal to the circuit interface of the reactor. The reactor will start up and produce heat at a certain efficiency (see the two corresponding signals on the circuit interface).
To shut down the reactor either let it run out of fuel cells or send the SCRAM Control Signal to the reactor circuit interface.
Be aware that the SCRAM process takes some time and the reactor will still produce heat until it is fully stopped.

What is the point of maximum output and efficiency?

Power output and fuel efficiency are changing dynamically depending on the reactor core temperature and the number of connected neighbor reactors. Additionally, the output of extra empty fuel cells of the breeder reactor type changes according to the temperature. To connect a reactor neighbor simply connect them with heat-pipes into one heat network. The reactors don't have to touch each other.

There are two possible options how output and efficiency are calculated, which can be changed in the settings.
By default Ownly's formulas will be used. In short this means: the hotter, the better. The higher the reactor core temperature is, the higher power output and fuel efficiency will be.
The alternative Ingo's formulas work a little different. Power output will also increase with higher core temperature, but efficiency will have a certain maximum, after which it will start to drop quickly again.

What is a reactor core meltdown?

When the reactor core reaches 1000°C a reactor core meltdown is caused. The reactor explodes and leaves a ruin behind. That ruin produces permanent radiation around and generates radioactive clouds. These clouds pollute large areas around the reactor ruin. The radiation effect is damage to all lifeforms in proximity. To stop the radiation spreading, a sarcophagus must be built over the reactor ruin, then the radiation will slowly decay.
