## What is RBMK Lab?

RBMK Lab: Nuclear Power Plant is an educational, offline reactor simulator for exploring how control rods, coolant flow, feedwater, turbine load, void fraction, pressure, and temperature can interact in a reduced-order model.

Run a stable case, trigger a controlled shutdown, or deliberately explore a feedback-prone case. Adjust one control at a time and watch the model explain which feedback terms are moving power.

Designed for curiosity and systems thinking, not operation. The app does not reproduce a real plant, predict an accident, train operators, or provide safety, engineering, or emergency guidance. Its equations are deterministic, documented in the product, and covered by Python and Swift contract tests.

No account, network connection, microphone, camera, analytics, advertising, or tracking is required.
