About this Mod

About

Create nuclear is a mod that adds a whole nuclear system to the create mod. An optimized reactor produces over two millions SU.

Create nuclear also adds Uranium ores and all the refining process to create and power the reactor automatically even from infinite sources like cobblestone with a complex refining process that exploits all the potential of create appliances.

Frequently Asked Questions

Create Nuclear server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Create Nuclear compatible with fabric and forge and neoforge?

Create Nuclear officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Create Nuclear – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Create Nuclear consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
