According to a Bloomberg email, Brookfield Renewable Partners, a clean-energy investor, and Cameco, a uranium fuel supplier, said they would acquire Westinghouse Electric, an American nuclear-power firm, in a $7.9bn deal. The energy crisis in Europe and soaring oil prices have sparked renewed interest in nuclear power. Tim Gitzel, Cameco’s boss, said the sector is “witnessing some of the best market fundamentals we’ve ever seen.”
