Extreme Reactors 2 Calculator

Desktop Required

The Extreme Reactors 2 Calculator is not accessible on small screens. The planner requires a larger display to properly view and edit reactor layouts. Please use a desktop or laptop for the full tool.

About

This project is an interactive planner for designing and simulating Extreme Reactors 2 reactor layouts before building them in game.

The calculator provides real time feedback for power generation, fuel usage, heat, and efficiency.

Features

Real Time Simulation

View RF/t, steam output, heat, and fuel usage instantly.

Layout Planning

Test moderators and fuel rod arrangements before building.

Accurate ER2 Logic

Simulation behavior is based on Extreme Reactors 2.

Open Source

Publicly available and open to community contributions.

Inspiration

This project was inspired by the original Big Reactors planner at br.sidoh.org, recreated for Extreme Reactors 2 with a modern interface and updated simulation support.

The goal was to create a fast and accessible way to design, test, and optimize reactors without relying entirely on in game experimentation.
