Life Extension

CANDU reactors can operate economically and reliably for up to 60 years. After about 30 years of operation, reactor core component replacement gives another 30 years. The project that allows for the reactors continued operation is called life extension.
All utilities that operate CANDU reactors are actively planning on life extension. The benefits are clear:

  • Ongoing operation is economically competitive compared to all other alternatives
  • Excellent public support for continued operation and especially high public support near the plant
  • Clear environmental benefits
  • Ongoing development of high technology and innovation in the region, and a positive socio-economic contribution, for an additional 25 to 30 years

Candu Energy Inc. is uniquely able to undertake the life extension projects due to:

  • People – a core team of hundreds of staff already working on life extension projects
  • Resources and technology – 15 years of investment to improve the core retubing schedule, cost and technology successfully used in the four units at Pickering A in the 1980s
  • Proven track record – we apply the project management expertise and technology used to deliver the last 6 new CANDU reactors on time and on budget
  • Our ongoing improvement as the original design agency for CANDU units, including those recently built and successfully operated

In August 2011, Argentina’s NA-SA hired Candu Energy Inc. to provide life extension services to the Embalse nuclear power plant. This followed the successful life extension of Korea’s Wolsong 1 reactor, which was completed in July 2011.

Candu Energy Inc. is currently wrapping up life extension projects at Bruce 1 and 2 units in Ontario, Canada and it has been subcontracted to continue the life extension of the Point Lepreau nuclear power plant in New Brunswick, Canada.

In accordance with a contract signed in late 2008, Candu Energy Inc. will also be subcontracted to deliver life extension services to the Gentilly-2 reactor in Quebec, Canada.

New Build

Proven Project Management Expertise - On Time, On Budget

Candu Energy Inc. employees have been building reactors almost continuously for the past 30 years. It has the strongest project management delivery capability of any nuclear vendor in the world and has designed, built and delivered six CANDU 6 reactors to international customers in the last decade. All of these projects have been delivered on or ahead of schedule, and on budget.
