Candu is in an industry of its own, the nuclear reactor has been credited with promoting nuclear development in China, India and South Korea. Though sales of CANDU reactors have historically been strong in the last decade they have dwindled, the direct result of it being a crown corporation under the direction of an overly protective/selective government (wouldn't allow for any risk, that affected its ability to get contracts signed with eager clients). CTV News: Ottawa to sell Atomic Energy of Canada Ltd. to SNC-Lavalin The nuclear reactor business is also highly political in nature meaning Canadian companies have to work harder than their counterparts to secure foreign contracts; traditionally American companies have had the edge however SNC Lavalin has shown itself to be more than capable of competing in such an environment (has obtained many large concessions in foreign countries, has pushed on in countries like Algeria even after a terrorist bomb killed a dozen of its employees in 2008).
All criticism of nuclear energy stems from safety concerns regarding meltdowns and weapons grade by products however those problems can be avoided simply by converting reactors to thorium fuel based from uranium based. (Cosmos:New age nuclear) Additionally, CANDU reactors (newest of the 34 used globally, was commissioned in 2007 in Romania, Romania has also ordered another one for 2013) use natural uranium and the radioactive water doesn't directly power turbines to create electricity, rather it stays in a secondary closed loop that can readily be made to release excess heat into the atmosphere rather than the water (unlike Fukushima Dai-Ichi). (SFGate:Canada Sells AECL's CANDU Reactor Division to SNC-Lavalin) In Qinshan, China, Candu reactors have been shown to operate on thorium meaning that even before New Generation nuclear reactors are widely accepted, SNC-Lavalin has access to technology that's already ahead of the competition. (World Nuclear Association: Thorium)Although Generation IV reactors haven't yet been produced by Atomic Energy of Canada, the Canadian government has invested billions of dollars into cutting edge research carried out by the company. (Natural Resources Canada: Priority Area:Next-Generation Nuclear Energy Technologies) AECL's Enhanced CANDU 6 (EC6) has Generation III features and is the only medium sized reactor capable of being implemented on smaller grids. The Enhanced Candu 6 gives customers the option of using either thorium, uranium or other popular fuels. (Atomic Energy of Canada Limited 2010 Financial Report)
Thorium based rectors yield 200 times as much energy as those fueled by uranium. Though safe, other renewable sources are expensive costing as much as five times the price per kWh produced when compared to coal (23 cents versus 4 cents).
Furthermore, energy consumption experienced the biggest yearly increase since 1973 in 2010, in 2010 it was up 5.6% largely due to China (up 11.2% surpassing the USA) and non-OECD nations (63% higher than 2000 levels). (World energy consumption up 5.6% in 2010, biggest rise since 1973: BP) Nuclear energy accounts for about 7.8% of the world's energy needs (24 out of 470 million BTU's (2011 pace as of August).
