Create: Going Nuclear

A nuclear power addon for Create (Minecraft 1.21.1, NeoForge 21.1). You mine rare uranium, process it with Create machines, enrich it, build a real pressurised water reactor, turn its heat into rotation, and try not to blow it up.

Features

Uranium and radiation

• Very rare uranium ore and radioactive caverns deep underground (walls full of ore, contaminated puddles, own biome).
• Physics-based radiation in real units (µSv/s, mSv): inverse square law, shielding by block thickness, alpha/beta/gamma, half-lives.
• Hazmat suit (alpha, beta) and lead suit (gamma), Geiger counter, dosimeter, HUD gauge, radiation sickness stages.
• Anti-Rad pills and an injector, both with first person animations.

Processing with Create

• Crushing, a sequenced assembly (spout, press, deployer) for yellowcake, nitric acid in a heated mixer, dissolving, bottling with the spout.
• Gas centrifuge cascade (stacked, driven by Create rotation) enriches uranium up to 5 percent.
• Buckets of every mod fluid, usable as Smart Fluid Pipe filters.

The reactor (5x5x6, built layer by layer)

• Reactor Casing (connected textures), Reactor Glass, Fuel Channels, Graphite Moderator, Control Rods, Controller.
• One Reactor Nozzle block with five modes: hot leg, cold leg, fuel, waste, relief valve.
• Point kinetics with delayed neutrons, k-effective, xenon poisoning, decay heat, Doppler feedback, coolant flow and pressure model.
• The Steam Generator is a heat exchanger and a generator: up to 2.2 million stress units, scaled by the hot coolant flow, and it also heats a Create boiler tank.
• The relief valve blows off steam that condenses back to water (faster with ice around).
• Random small incidents, automatic SCRAM only in an emergency.
• Control Desk (SCADA style GUI): dials, charts, event log, rods, pump, valve, SCRAM, Redstone Link frequency slots.
• Reactor Creator (creative): builds a complete working reactor with generator in one click.

Accidents

• Hydrogen and steam explosions, containment (concrete, lead or iron dome) with pressure, corium.
• Without containment: flashbang, shockwave that flattens the land and is heard from far away, flying reactor blocks, aftershocks, a final much bigger explosion, a dust column with a mushroom cap, and fallout.
• Fallout is carried by a slowly turning wind over up to 1000 x 1000 blocks. Leaves fall, grass turns to podzol and coarse dirt, plants wither. The Radiation Scanner shows the map and the wind.

Guides and extras

• Ponder scenes: building the reactor layer by layer, the nozzle modes, running it, heat to rotation, containment, control desk, uranium processing, enrichment.
• Advancements and English and Turkish translations.
