Explore The Warning, a new story set at Leningrad Unit 1 in 1975, alongside The Night of the Test at Chernobyl. New • Follow Leningrad’s restart decisions in a dramatized chapter built on its own teaching model. • Explore both stories through the same six views: core, plant overview, loop, turbine, feedwater and trends. Improved • Pause the night to inspect reactivity, rod positions, axial slices and Leningrad’s hot-channel proxy. • Read debrief power graphs with MWt, clock times and a labelled logarithmic scale. • Open source links and see clearer distinctions between historical accounts and model assumptions. Fixed • Addressed crashes when dragging reactor controls and displaying debrief objectives. Both historical chapters use simplified teaching models; they are not operator training or engineering guidance.
Two historic nights. One reactor design. Your decisions. 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 • 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.
