Future realism upgrades
- Steam generator UA·ΔT_lm heat exchange and pump head/flow curves; keep validating temps under nominal load.
- Rod banks with worth curves, xenon/samarium buildup, and delayed-group kinetics per bank.
- 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.
- 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.
- Incremental realism plan:
- Add stored enthalpy for primary/secondary loops and a steam-drum mass/energy balance (sensible + latent) while keeping existing pump logic and tests passing. Target representative PWR conditions: primary 15–16 MPa, 290–320 °C inlet/320–330 °C outlet, secondary saturation ~6–7 MPa with boil at ~490–510 K.
- Adjust HX/pressure handling to use stored energy (saturation clamp and pressure rise) and validate steam formation with both pumps at ~3 GW. Use realistic tube-side material assumptions (Inconel 690/SS cladding) and clamp steam quality to phase-equilibrium enthalpy.
- Update turbine power mapping to consume steam enthalpy/quality and align protection trips with real steam presence; drive inlet steam around 6–7 MPa, quality/enthalpy-based flow to ~550–600 MW(e) per machine class if steam is available.
- Add integration test: cold start → gens/pumps 2/2 → ramp to ~3 GW → confirm steam quality threshold at the secondary drum → enable all turbines and require electrical output. Include a step that tolerates one secondary pump off for a period to prove redundancy still yields steam.
