Two historic nights. One reactor design. Your decisions.
No nuclear degree needed: every control says what it does, your first shift starts with a single fader, and every trip comes with the reason why.
THE WARNING: LENINGRAD 1975
Play a dramatized story at Leningrad Unit 1 on a simplified teaching model. Make restart decisions, explore the reactor and compare your run in the debrief. Historical context and model assumptions are distinguished.
THE NIGHT OF THE TEST
• The night of the turbine test at the real clock times, played on a dedicated teaching model
• Every historical beat cites its source; the crew appears by role, never by name
• Eight decisions where you can choose differently, and twelve endings to find, from the safe ones to the choices that would not have saved it
• Look inside the core: the operating margin, the steam voids and the rods, slice by slice
SHIFTS
• The dispatcher calls for load. Work the rods, feedwater, bypass and pumps to deliver it without tripping the unit
• Six career shifts and a new daily shift every day, the same for every operator
• Stars, personal bests, ranks from Trainee to Chief engineer, and Game Center leaderboards
• A shift log after every shift: your load trace, your closest call, and exactly why the unit tripped
THE CONTROL ROOM
• A glowing reactor lid with 1,872 channel caps, needle meters, an annunciator wall, tactile faders and AZ-5 under a flip cover
• One live plant board in every mode: zoom from the whole plant to the loop, turbine, condensate or feedwater, or open it full screen
• A trend recorder, and synthesised plant sound with a one-tap mute
LEARN WHY IT REACTS
• How it works: nine short chapters over the live plant, from fission to AZ-5
• Guided training drills with predictions and causal debriefs
• A sandbox with more than a dozen faults to inject
• Reference notes on every signal
Plays offline. No account, no ads, no tracking. One optional lifetime Pro unlock adds the advanced shifts and drills and the design what-ifs for the night.
RBMK Lab is a game and a learning tool built on simplified, teaching-scale models. The 1986 chapter is a sourced, dramatised reconstruction tuned to the published sequence of events. It is not evidence about the accident's cause, and nothing in the app is operator training or engineering guidance.
