CARLO FUSION REACTOR (CFR‑1): A COMPLETE HIGH‑FIELD TOKAMAK BLUEPRINT FOR GRID‑SCALE POWER

The Carlo Fusion Reactor (CFR‑1) blueprint presents a complete, engineering‑rigorous design for a deployable high‑field compact tokamak intended to deliver continuous 150–200 MW_e baseload fusion power. It defines every subsystem required for a real fusion power plant, integrating manufacturable REBCO HTS magnet assemblies capable of producing 10–12 T fields; reactor‑grade D–T plasma physics achieving n≈1×10²⁰ m⁻³, T≈15 keV, τ_E≈1 s; and a tungsten first‑wall and divertor system engineered for multi‑MW/m² heat flux and long‑term irradiation resilience. Surrounding the vacuum vessel, the liquid‑metal breeder blanket (LiPb or FLiBe) provides tritium breeding ratios above 1.1, captures 14.1 MeV neutrons, and extracts 500–700 MW_th of high‑temperature heat. This heat is routed through a high‑temperature thermal‑hydraulic loop into a supercritical CO₂ Brayton cycle operating at 40–50% efficiency, enabling realistic net electrical outputs of 150–200 MW_e after accounting for cryogenic, pumping, heating, and control loads. The blueprint details full tritium extraction, purification, storage, and closed‑cycle fueling systems; cryogenic infrastructure supporting HTS coils at 20–30 K; structural mechanics for neutron‑irradiated steel and composite casings; disruption mitigation via massive gas injection and shattered pellet injection; and remote‑handled maintenance workflows including blanket module replacement, first‑wall refurbishment, and hot‑cell operations. It incorporates activation‑aware lifecycle planning, cybersecurity‑isolated control systems with air‑gapped supervisory networks, multi‑layer SCRAM logic, containment architecture, and emergency response pathways. Beyond the core reactor, the document defines grid‑integration logic (load following, frequency/voltage support, black‑start capability), multi‑reactor scaling models that reduce CAPEX/OPEX, full economic analysis (CAPEX £2–4B, OPEX £80–150M/yr, LCOE £60–90/MWh), and long‑term upgrade pathways including CFR‑2, CFR‑X, CFR‑L, CFR‑H, and CFR‑S. Every subsystem is presented with realistic parameters, industrial constraints, ASCII system diagrams, and a complete operational ecosystem. CFR‑1 is not a concept sketch — it is a manufacturable, serviceable, scalable fusion power plant architecture designed for real deployment and global decarbonisation.
