Create: Going Nuclear

Create: Going Nuclear

A nuclear power addon for Create (Minecraft 1.21.1, NeoForge 21.1). Mine rare uranium, process and enrich it with Create machines, build a reactor (a boiling water reactor or an RBMK), turn its steam into rotation or electricity, deal with the spent fuel, and try not to blow it up.

Features

Uranium and radiation

• Very rare uranium ore and radioactive caverns deep underground, in their own biome: walls full of ore and contaminated puddles.
• Radiation simulated in real units (µSv/s, mSv). Covers the inverse square law, shielding by block thickness, alpha, beta and gamma, and half-lives.
• Hazmat suit against alpha and beta, lead suit against gamma.
• Geiger counter, dosimeter, a HUD with dose rate and total dose, and stages of radiation sickness.
• The Radiation Scanner shows the fallout map and the wind. The Purification Core clears dose, sickness, puddles and fallout around you.

Processing with Create

• Crushing, then a sequenced assembly (spout, press, deployer) makes yellowcake. A heated mixer dissolves it in nitric acid.
• A stack of Gas Centrifuges driven by Create rotation enriches the uranium. Each centrifuge is one stage, and 8 stages reach the 5 % fuel grade.
• Every mod fluid has a bucket, usable as a Smart Fluid Pipe filter.

Two reactor designs

• Boiling water reactor. A box of Reactor Casing between 3 and 15 blocks a side, with Reactor Glass, Fuel Channels, Graphite Moderator, Control Rod Drives and a Controller.
• RBMK. A graphite channel reactor with its own shield, graphite, fuel and rod channels, cap floor and console. It has a positive void coefficient and the scram power surge.
• Build your own core. You choose where the fuel goes. Moderation, leakage, power peaking and rod reach follow your layout, and the Control Desk shows them on a live core map.
• One Reactor Nozzle block with five modes: Cold Leg (water in), Hot Leg (steam out), Fuel, Waste and Relief.
• Two physics modes:
  • Simple (default): the power follows the rods.
  • Realistic: point kinetics with delayed neutrons, k-effective, xenon, decay heat, Doppler feedback, a coolant flow and pressure model, and a rod withdrawal block.

Steam and power, all with Create plumbing

• Steam runs in Create’s own pipes and fluid tanks.
• Steam Turbine turns steam into rotation. Hit it with a wrench and it makes Forge Energy instead (works with Create: New Age, Create: Power Grid and others). It lets its used steam out as Exhaust Steam.
• Low Pressure Turbine gets half as much power again out of the Exhaust Steam.
• Radiator turns steam back into water while an Encased Fan blows through it: the faster the fan, the more it takes.
• Steam Vent, a pipe end with holes on top, blows spare steam into the air.
• Reactor Heat Port hands core heat to Create: New Age heat pipes.

Control room

• Control Desk. A SCADA-style panel with dials, charts, an event log, rods, pump, valve, SCRAM and START. It has pages for the plant, the core, power and trends.
  • It links to its reactor by frequency: put two items in a reactor nozzle (sneak and right-click it) and the same two in the desk.
  • A Link page gives Redstone Link channels for SCRAM, rods in, rods out, alarm and power.
• Control Panel. Sits in the reactor wall, with a SCRAM button and the same Redstone Link channels.
• Physics Desk. A blackboard with the reactor physics, and a calculator for the critical rod position, xenon and decay heat.
• Safety Operator. A small AI runs the automatic protection. It reads the trends and first tries gentle steps:
  • starts the pump,
  • opens the relief valve,
  • drives the rods in a little.

  It scrams only when it has to, and you can switch it off completely.

Fuel cycle

• Spent Fuel Pool. Every delivery cools on its own clock under water.
• Dry Cask. Takes the cooled fuel and can be sealed and carried away.
• Reprocessing Plant. Recovers uranium and plutonium. Plutonium mixes into MOX fuel.
• High-level waste is vitrified in a heated press and buried behind a Repository Vault in a bentonite-lined chamber deep underground.

Accidents

• Hydrogen and steam explosions, and a containment dome (concrete, lead or iron) with its own pressure. Without it you get corium.
• Arcade disaster mode: a flash, a shockwave that flattens the land, flying reactor blocks, a mushroom cloud and fallout. The fallout drifts with a slowly turning wind over up to 1000 × 1000 blocks: leaves fall, grass turns to podzol and plants wither.
• Realistic disaster mode: a core meltdown and local contamination.

Guides and extras

• Ponder scenes for every block, from building the reactor layer by layer to steam, the control room and the fuel cycle.
• A full Operator’s Manual (PDF).
• The creative-only Reactor Creator builds a complete working plant in one click.
• Paintings, banner patterns, an armor trim, advancements, and English and Turkish translations.
• A small in-game notice when a new version is out on CurseForge. Nothing is downloaded by itself.
