This mod had several options and some new gameplay to the transplutonic mod.

• Settings

With this mode you can change the weight and power of each full cell.

You can change the nuclear reactor neighbors’ bonus and power output.

You can make the reactor automatically stop when heat reaches maximum.

• Recipe tweak

Change some recipe output especially used fuel recycle.
The weight of uranium is also tweaked.
1 U235/U238 weight 5Kg
And 1 uranium hexafluoride = 1Kg.
Recycle fuel will give back useful byproduct.

• Uresidu option

To not make it to complex the centrifuge only output one fluid, the lower concentrate is output as solid.That can be liquify in a special building.

• Thorium

You can add thorium fuel as a late nuclear fuel.
It differs from the other fuel as it doesn't come from recycling or from uranium ore.
You need to extract it from stone then purifier it and liquefied it.
You can put it in an inactive full cell. To activate the thorium, it needs to be irradiated in a breeder reactor.
At the end you can recycle it to get some uranium.

• Tritium

It adds a late game tritium recipe to make tritium for fusion without need to expand fuel cell.

You still need fission fuel to transform hydrogen into tritium.

The cycle goes as this.
Water->hydrogen
Put the tritium breeding cell in the breeder to transform it in tritium gas.

• To Do

  -Working on removing the dependency to transplutonic for people who want to tweak the vanilla Factorio.

  -Make thorium liquid in barrel

if you have any suggestions don't hesitate to post them in discussion.

A standalone Mod is in preparation.
I don't know yet if this mod will revert back to mainly settings tweaks or being a bridge between the 2 mod.
