Cameco Will Not Invest in New Brunswick Reactor
Saskatoon, Saskatchewan, Canada, July 29, 2005 . . . . . . . . . . . . . . .
Cameco Corporation confirmed today that it will not invest in the Point Lepreau nuclear generating station in New Brunswick. Point Lepreau, which is indirectly owned by the provincial government, is a 680-megawatt, Candu reactor similar to the Bruce reactors in Ontario.
Bruce Power Inc. submitted a proposal, on behalf of Cameco, TransCanada Corporation and BPC Generation Infrastructure Trust, to operate and refurbish the reactor. New Brunswick has decided to proceed with refurbishing the reactor and Bruce Power’s proposal was not accepted.
“It is another positive sign for the nuclear industry that New Brunswick has chosen to make a substantial investment in refurbishing its reactor after carefully considering the alternatives,” said Jerry Grandey, Cameco’s president and CEO. “We continue to look for other opportunities that are consistent with our vision to become a dominant nuclear energy company producing uranium fuel and generating clean electricity.”
Cameco, with its head office in Saskatoon, Saskatchewan, is the world’s largest uranium producer. The company’s uranium products are used to generate electricity in nuclear energy plants around the world, providing one of the cleanest sources of energy available today. Cameco’s shares trade on the Toronto and New York stock exchanges.
