Uranium Age
by mubduster
Uranium Age, a Fabric technology mod, adds uranium reactors, portable reactors and lead blocks that shield against radiation.
What it does
Uranium Age adds reactor blocks that run on uranium fuel and heat a furnace, blast furnace or smoker placed beneath them. Reactor Block needs a pre-made core and requires Reactor Controls, and its recipe calls for boron rods or a boron ingot together with a uranium ingot or uranium block. A reactor keeps running until its uranium fuel is used up, and the boron ingot is removed to shut it off. Portable reactors come in a portable uranium reactor and a portable uranium block reactor form, both of which can be placed.
Uranium is radioactive and hurts players and living entities such as sheep. Lead blocks placed around a uranium block stop the radiation from going in that direction, in the same way a sculk sensor is shielded. Players should know how close they get to uranium ore, since mining and moving through caves can expose them to radiation. The mod also lets uranium be used to craft traps. An ingot lasts a long time as fuel, while a block burns faster and costs more to use.
Uranium Age runs on client and server, so the server and every player need it. Files are published for Fabric only, for 26.1.2 and as the latest version, 1.0.1 for 26.1.2. The mod is released under the CC0 1.0 Universal license and is not open source.
Key features
Uranium reactors
Reactor blocks take uranium fuel and heat the furnace, blast furnace or smoker set under them until the fuel runs out.
Portable reactors
Portable uranium reactor and portable uranium block reactor versions can be placed wherever they are needed.
Radiation and lead shielding
Uranium radiation hurts players and living entities, and lead blocks placed beside a uranium block block radiation from that side.
Uranium traps
Uranium can be used to craft traps, and an ingot fuel lasts longer than a block fuel.

What the author says
This is the second mod I have published. This radiation can be blocked by placing Lead Blocks around it, just like you can do with the sculk sensor. Place a lead block on one of the faces of the Uranium block in question, and it will block all radiation from going in that direction.
