Uranium Fuel Air Delivery for Rooppur Nuclear Power Plant Unit 2 in Bangladesh Delayed
Recently, the first batch of uranium nuclear fuel transport cargo flights for Unit 2 of Bangladesh's first nuclear power facility—the Rooppur Nuclear Power Plant (RNPP)—was forced to be suspended, resulting in the postponement of the originally scheduled delivery. The batch of nuclear fuel was originally planned to arrive by air on September 24 at Hazrat Shahjalal International Airport in Dhaka, the capital of Bangladesh. Faqir Mahbub Anam, Minister of the Ministry of Science and Technology of Bangladesh, stated that the cargo charter flight carrying the uranium fuel was originally scheduled to land on the 24th, but because it was not granted permission to enter Pakistani airspace, the flight could not proceed as scheduled, and the specific reason why Pakistan has not yet approved the airspace permit remains unclear. Anam added that the Russian side has provided a new timetable, and it is expected that this batch of uranium fuel will arrive in Bangladesh in the first week of October.
