C.O.R.E. feature set

• Core physics: point-kinetics with delayed neutrons, temperature feedback, fuel burnup penalty, xenon/iodine buildup with decay and burn-out, and rod-bank worth curves.
• Rod control: three rod banks with weighted worth; auto controller chases 3 GW setpoint; manual mode with staged bank motion and SCRAM; state persists across runs.
• Coolant & hydraulics: primary/secondary pumps with head/flow curves, power draw scaling, wear tracking; pressure floors tied to saturation; auxiliary power model with generator auto-start.
• Heat transfer: steam-generator UA·ΔT_lm model with a pinch cap to keep the primary outlet hotter than the secondary, coolant heating uses total fission power with fuel heating decoupled from exchanger draw, and the secondary thermal solver includes passive cool-down when flow is low.
• Pressurizer & inventory: primary pressurizer trims toward 7 MPa with level tracking, loop inventories/levels steer flow availability, secondary steam boil-off draws down level with auto makeup, and pumps reduce flow/status to CAV when NPSH is insufficient.
• Steam cycle: three turbines with spool dynamics, load dispatch to consumer, steam quality gating for output, generator states with batteries/spool.
• Protections & failures: health monitor degrading components under stress, automatic SCRAM on core or heat-sink loss, relief valves per loop, maintenance actions to restore integrity.
• Persistence & ops: snapshots auto-save/load to artifacts/last_state.json; dashboard with live metrics, protections/warnings, heat-exchanger telemetry, component health, and control shortcuts.
