  "description": "The station operator runs two units and their support stores. Each unit generates power into the station switchyard, which exports to the grid against the dispatch schedule. The chemistry lab doses the primary and secondary circuits, planned outages draw maintenance spares, and fresh fuel is received and loaded into the core.",
