Canada Plans World's Biggest Nuclear Plant In Ontario (financialpost.com) 92

Posted by BeauHD from the energy-of-the-future dept.
Bruce Power, a Canadian utility company, is planning to build the world's biggest nuclear plant as growing demand for clean energy spurs interest in atomic energy. The Financial Post reports: The Ontario government said Wednesday Bruce Power will conduct an environmental assessment of adding as much as 4.8 gigawatts of capacity to its plant in Canada's most-populous province. The plant's eight reactors currently have about 6.2 gigawatts of capacity and supply 30 per cent of the province's power. The expansion would make the site larger than Japan's Kashiwazaki-Kariwa plant, the biggest in the world with seven reactors and more than eight gigawatts of capacity.

  • The fault line runs under the Pickering plant, not the Bruce plant.

    And why isn't anyone looking into grabbing tidal power from the Bay of Fundy? We have enough potential tidal energy waiting to be captured to cover over 60% of our current use. I'd really like to see that tapped before we expand our nuclear power generation.

    Also... sorry, NF, but we oughta screw the tourists and divert more water for hydro generation too.

      Because theoretical total amounts of power of natural phenomenon are useless. Look at it this way, you have to generate X amount of power. That means you need Y * X amount of generators which require rare earths which are very environmentally costly. So you want Y to be as close to 1 as possible. If you use tidal, Y is going to be twice what it is for nuclear at least. So this way you create fewer lakes of acid in Asia.

      They have looked into it. As you'd expect, it's not reliable or economical. "There's enough potential energy" is a starting point, but not close to a convincing argument for it. Real answers would only be sufficient if they provide a realistic analysis of it's levelized cost of electricity (LCoE), and its full lifecycle carbon emissions including those of producing its fuel. Once you've got those numbers, you begin to understand just how good we have it with nuclear.

It is also expensive and impacts marine life. Nuclear is great for base power demands. It provides very consistent power 24/7.

        Perhaps that is true but there's something to be said for economy of scale.

        Each nuclear power plant site has to have some given amount of staff for security and maintenance regardless of how many reactors are on the site. Put more reactors there and this cost can be spread out over more energy sold. There's going to be a point of diminishing returns so we should not plan on all eggs in one basket.

      It was actually discussed in Alberta and part of the plan was actually to use the heat to extract oil from the oil sands [wikipedia.org].

      Either way, the project eventually got nimby'd into oblivion (though it might have just be economics as well).

      • The project, led by the same Bruce Power, was nixed when AECL sent out the new price estimate for ACR-1000, which was three times the initial estimate. That made it economically impossible. This is all well recorded and easily gogelgleable.

        But sure, blame those nimbies if it makes you feel better.

        While the planned unit is probably a Candu design, the two ABWR's at Kashiwazaki-Kariwa went from Construction to commissioning in around 4 years, as did the first 6 BWRs, so it can be done. A lot depends on the licensing regimen and how well the the process is managed.

          Kashiwazaki-Kariwa might not be the best example. It was shut down due to an earthquake that went beyond its design limits, and required major changes to make it safe. In other word, they skimped on the geological survey, the design, and construction.

          Then it shut down again due to the same earthquake that damaged Fukushima Daiichi. It hasn't restarted since, because now that there is increased scrutiny and some new geological data, it seems like it was a bad idea to build it there in the first place.

      Plant is a bit of a misnomer - the Bruce plant consists of 8 reactors and would add a ninth to the plant. You are correct in that it's not a new 11 GW unit, but a new 4.8 GW unit. 4.8GW is likely an addition of several CANDU reactors.
