- 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. - Adjust HX/pressure handling to use stored energy (saturation clamp and pressure rise) and validate steam formation with both pumps at ~3 GW.

- 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. - 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. - 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.

- [ ] Dashboard follow-ups: clarify or replace turbine “Steam P” field (currently shows loop pressure, not turbine-driving steam); consider removing it if no better signal is available. - [x] Dashboard follow-ups: replace turbine “Steam P” with a more useful steam availability signal (enthalpy × steam flow).
