A shipment of nuclear fuel for Bangladesh’s flagship Rooppur Nuclear Power Plant has been delayed after Pakistan denied overflight clearance to a Russian aircraft transporting the cargo, raising fresh questions about regional transit routes and the movement of sensitive strategic materials.
The consignment, carrying uranium fuel assemblies intended for the second reactor at the Rooppur facility, was scheduled to arrive in Bangladesh on 24 September. However, the aircraft was unable to transit through Pakistani airspace, forcing a postponement of the delivery and triggering discussions among Bangladesh, Russia and aviation authorities over alternative arrangements.
Pakistan has rejected suggestions that the decision was politically motivated. Officials described the matter as a technical and procedural issue, explaining that overflight permissions involving sensitive cargo are subject to established international aviation rules and may require approvals from multiple agencies before clearance can be granted.
The delay is expected to temporarily affect logistics associated with the commissioning schedule of the second reactor. Russian officials have reportedly proposed the first week of October as a possible revised arrival window, although the final timeline will depend on routing approvals and flight planning.
The Rooppur Nuclear Power Plant, located in Bangladesh’s Pabna district, is the country’s first nuclear energy project and one of the largest infrastructure developments in its history. Built with extensive Russian assistance, the facility consists of two VVER‑1200 reactors with a combined generating capacity of 2,400 megawatts. Once fully operational, it is expected to play a crucial role in meeting Bangladesh’s rising electricity demand and reducing dependence on imported fossil fuels.
Energy experts note that transporting nuclear fuel is a highly regulated process involving strict security, safety and diplomatic coordination. Even minor disruptions in airspace access can force significant changes to delivery schedules.
While authorities do not expect the delay to alter the project’s long‑term outlook, the incident highlights how geopolitical and aviation‑related decisions can influence major energy projects. For Bangladesh, ensuring the timely arrival of fuel remains critical as it moves closer to bringing its second reactor into service.
