    \textbf{Small Modular Advanced High Temperature Reactor (SmAHTR):}
    - Liquid-salt cooled reactor design
    - Well-documented startup procedures
    - Representative of next-generation SMR designs

    \textbf{Startup Sequence:} Cold → Controlled Heating → Approach Criticality → Low-Power Physics → Full Power
    Each mode has different control objective (temp control, ramp rate, reactivity, neutron flux, load following)

    \textbf{Implementation Platform:}
    - Simulation: High-fidelity Simulink model (thermal-hydraulics + neutron kinetics)
    - Hardware: Emerson Ovation control system (industry standard)
    - Integration: ARCADE platform (hardware-in-the-loop)
    - Validation: Real-time performance on actual control equipment

    \textbf{Why This Matters:}
    Multiple coordinated subsystems, strict timing/temperature constraints, complex nonlinear dynamics.
    This is not a toy problem---it's representative of deployment challenges.
