Brazil has two nuclear reactors generating about 3% of its electricity. Construction began on a third reactor in 2010, was suspended in 2015, and recommenced in November 2022. The country's first commercial nuclear power reactor began operating in 1982.

This report examined the need for Russian secondary supplies from the time of the report until 2013 (which was fairly well known) and the continued need for secondary supplies after the HEU deal expired in 2013.

Life-cycle analysis is useful for comparing net energy yields from different methods of electricity generation. Nuclear power shows up very well as a net provider of energy. External costs, evaluated as part of life-cycle assessment, strongly favour nuclear over coal-fired ge...

Uzbekistan has considerable mineral deposits, including uranium. Today, most uranium is mined in the middle of the country, with Navoi as the centre, linked to mines by railway.  Construction of two large Russian reactors is planned.

About 10% of the world's electricity is produced from nuclear energy. Most nuclear electricity is generated using just two kinds of reactor. New designs are coming forward and some are in operation as the first generation reactors come to the end of their operating lives.

Niger has two significant uranium mines providing about 5% of world mining output from Africa's highest-grade uranium ores. Niger's first commercial uranium mine began operating in 1971.

Used nuclear fuel has long been reprocessed to extract fissile materials for recycling and to reduce the volume of high-level wastes. New reprocessing technologies are being developed to be deployed in conjunction with fast neutron reactors which will burn all long-lived acti...
