- [x] Flesh out condenser behavior: vacuum pump limits, cooling water temperature coupling, and dynamic back-pressure with fouling.
- [ ] Dashboard polish: compact turbine/generator rows, color critical warnings (SCRAM/heat-sink), and reduce repeated log noise.
- [ ] Dashboard multi-page view (F1/F2): retain numeric view on F1; future F2 schematic should mirror real PWR layout with ASCII art, flow/relief status, and minimal animations; add help/status hints and size checks; keep perf sane.
- [ ] Core thermal realism: add a simple radial fuel model (pellet/rim/clad temps) with burnup-driven conductivity drop and gap conductance; upgrade CHF/DNB correlation (e.g., Groeneveld/Chen) parameterized by pressure, mass flux, and quality, then calibrate margins.

- [ ] Transient protection ladder: add dP/dt and dT/dt trips for SG overfill/depressurization and rod-run-in alarms; implement graded warn/arm/trip stages surfaced on the dashboard.
- [ ] Chemistry & fouling: track dissolved oxygen/boron and corrosion/fouling that degrade HX efficiency and condenser vacuum; let feedwater temperature/chemistry affect steam purity/back-pressure.
- [ ] Balance-of-plant dynamics: steam-drum level controller with shrink/swell, feedwater valve model, turbine throttle governor/overspeed trip, and improved load-follow tied to grid demand ramps.
