## Future realism upgrades

- Implement steam generator UA·ΔT_lm heat exchange (done), pump head/flow curves (done); validate against target temps under nominal load.
- Next up: rod banks with worth curves and delayed groups, plus xenon/samarium buildup tied to power history.
- Add pressurizer behavior, primary/secondary inventory and level effects, and pump NPSH/cavitation checks.
- Model feedwater/steam-drum mass-energy balance, turbine throttle/efficiency maps, and condenser back-pressure.
- Introduce CHF/DNB margin, clad/fuel split temps, and SCRAM matrix for subcooling loss or SG level/pressure trips.
