Czech power utility (CEZ) and AREVA have signed a major 15-year uranium enrichment services contract for the Temelin nuclear power plant.

The deal will contribute to securing CEZ’s long-term nuclear fuel supply, according to Areva.

CEZ operates a fleet of six nuclear reactors, on the Dukovany and Temelin sites, which provide 31% of the Czech Republic’s electricity generation.

The Czech utility has recently announced its intent to increase its fleet of nuclear reactors, with the construction of two new units during the next decade.
