I have come up with some changes to nuclear reactors which would make it more of a hassle to set up. Currently it is quite simple to set up a nuclear reactor in your wooden hut.
1) Output Fluctuates
Rather than having a steady output, nuclear reactors have an irregular output. I propose to accomplish this by applying a 90% success rate to uranium cell ticks, if a uranium cell does not tick successfully then the surrounding cells cannot tick with the failed cell on that tick. This way the bigger the nuclear reactor the bigger the fluctuation.
2) Capacitor Array (Internal Reactor Component)
Capacitive arrays will attempt to keep the nuclear reactor at a constant output. They will attempt to keep their charge at 50%. They can exchange EU at a rate of 5 eu/t. The more you place in the reactor the more energy can be exchanged per tick.
3) Lapcap Array (Internal Reactor Component)
The same as a Capacitor array but can exchange 25 eu/t.
4) Lapanium
Some people of the community have been asking for a long time for an alternate form of uranium, here is my idea for it. First you compress lapis, into lapis cell. Then you put it into a very hot reactor until it turns into a Lapanium cell. Lapanium cell produce the same amount of energy as uranium but twice the heat and last for a tenth of the time.
I am open to suggestions for the recipes
