BasicNuclearCraft
by Avast59
BasicNuclearCraft lets players gather uranium and lead ore, and smelt them into blocks and ingots for a semi-realistic radiation system.
What it does
BasicNuclearCraft is a Fabric game mechanics mod for 1.21.1 that adds a semi-realistic radiation system. It brings radiation protective clothing, an armor set, and a nuclear reactor along with reactor sickness effects. Uranium and lead appear as ores, raw materials, ingots, nuggets and blocks, with uranium ore generating below y=8 and lead ore below y=60. Only the smelted block variants emit radiation.
The mod adds tools and utilities for dealing with radiation, including a dosimeter in five tiers that reads dose rates from up to 100 Sv/h at the lowest tier to up to 5 Sv/h at the highest. Empty and filled fuel rods feed the reactor, which hands out loot in a random table of diamonds, ancient debris and netherite ingots. Commands are included for working with the system.
Every player and the server need a copy of the mod. Files exist for Fabric only, for 1.21.1, with version 1.1.0 as the latest, released 2026-09-05. The mod is released under All rights reserved and is not open source.
