Real reactor physics, with guided walkthroughs that take you from cold shutdown to full power and back right in your browser.

The live plant is the SLS-100, a compact single-loop PWR (~100 MWe) — cold shutdown to full power, with procedures and failures on the same model. Start with About for what this is and how to approach it.
Run the board: rods, boron, pressurizer, feed, steam, turbine, and alarms. Learn the order of a startup and how to hold the plant online — the what operators do. Free play: every start condition, every control live.
Core, primary, steam generator, and turbine are one coupled model. A load change or a trip has consequences you can reason about — the why behind the board. Model form and limits are on the Physics page.
Trips, stuck valves, pump trips, sensor failures, tube leaks, loss of heat sink — inject them yourself and work the recovery. Same plant every session; an easier run is a gentler situation, not a simpler model.
A commercial-format manual set for this plant, open in the control room: controls and indications, normal and emergency procedures, alarm response, setpoints and limits, and a glossary.
