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
- The SLS-100 pressurized water reactor in free play, cold shutdown to full power
- Six walkthroughs — startup and shutdown in three parts each, graded live against the plant, step by step
- A five-minute guided opener at full power, on the Instructor tab
- Injected plant failures, with a free-play debrief after a trip or failure
- Containment: pressure, temperature, spray and fan coolers
- The plant saves itself in your browser; the Main Menu offers Continue
- Operator’s manual, in the control room and on this site
- Offline single-file download
- Physics write-up of the plant model
Nearly there — built, in final review
Written and running, held back until each one is played end to end. The campaign and scenarios were written for the plant’s previous physics engine and are being re-checked against the new one.
Three Mile Island walkthrough
The 1979 accident, step by step on this plant: a relief valve sticks open and the pressurizer level rises while the coolant drains.
Training campaign
A guided path from first skills toward full operation: missions that watch the board and gate progress through real procedures.
Scenarios
Instructor-led situations, one lesson each, from normal evolutions to casualties.
In progress — being worked on now
- Performance on long sessions and on computers without graphics acceleration
- Shorter, clearer walkthrough steps
- Control-room usability fixes from player reviews
Later
More of the SLS-100
- More injectable failures: steam-line break, a single stuck rod, loss of condenser vacuum
- Turbine load following
- Response checklists for the core casualties
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.
