## Future realism upgrades

- Steam generator UA·ΔT_lm heat exchange (done) and pump head/flow curves (done); keep validating temps under nominal load.
- Rod banks with worth curves and xenon/samarium buildup (done); extend with delayed-group kinetics per bank.
- 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.
