Roadmap
What is open now, what is closest to shipping, and what comes after.
Dates are not promised. The order below is, as far as anything in a one-person project is: it is the order things are actually being worked in. What ships shows up in the changelog.
Open now
- PWR free play, cold shutdown through full power
- Operator manuals in the control room
- Injected plant failures and free-play recovery
- Offline single-file download
- Physics write-up of the plant model
Nearly there — built, in final review
These four are written and running. They are held back because each mission and procedure is being played end to end before it ships, and an instructor that grades you against a step it has not been checked on is worse than no instructor at all.
Training campaign
A guided path from first skills toward full operation: missions that watch the board and gate progress through real procedures, not click-through slides.
Scenarios
Instructor-led situations — one lesson each — from normal evolutions to casualties, including longer story sequences such as Three Mile Island.
Live checklists
Procedures that tick themselves off against the plant as it sits: you operate, the checklist grades the instruments. Free-play practice without a full scripted mission.
Procedure walkthroughs
Step-by-step follow mode in the Instructor panel: the same manual procedures, advanced one step at a time with the plant checked as you go.
In progress — being built now
Containment safeguards
The containment building went in with pressure, temperature and a sump. Next are the systems that fight back: containment spray and fan coolers on their own actuation setpoints, and after that hydrogen behavior — the mechanism that made Three Mile Island’s second day worse than its first.
Later
BWR and RBMK control rooms
Both physics engines already exist, and both pass their own test suites — a boiling-water plant and a graphite-channel plant, running in the open-source repository today. What is missing is not the physics; it is the control room, the instrumentation and the procedures around each one, which is most of the work a plant actually takes. They are deliberately parked until the PWR is finished, because three half-built plants would teach less than one whole one.
The RBMK is worth the wait on its own: a positive void coefficient is a plant-dynamics lesson that reading about it does not deliver the way operating one does.
