[T]he report’s executive summary certainly gets to the heart of their findings.
“The rhetoric from small modular reactor (SMR) advocates is loud and persistent: This time will be different because the cost overruns and schedule delays that have plagued large reactor construction projects will not be repeated with the new designs,” says the report. “But the few SMRs that have been built (or have been started) paint a different picture – one that looks startlingly similar to the past. Significant construction delays are still the norm and costs have continued to climb.”
“Base load” is not that much. Off shore wind is almost always blowing, and all the other renewables can be stored via batteries or hydrogen (or tanks, in case of biogas). Yes, that’s a whole lot of stuff, but the technology exists, can be produced on large scale and (most importantly) doesn’t cause any path dependencies.
Nuclear is extremely expensive, as the article highlighted. And to be cost effective, power has to be produced more or less constantly. Having a nuclear power plant just for the few hours at night when wind and sun don’t work is insane - and insanely expensive.
Nuclear is mostly expensive because of regulations and red tape that are mostly built upon FUD.
That needs to be re-addressed from the ground up. There needs to be a big PSA push on the safety of nuclear and on the true costs and hidden dangers of coal and oil plants to build massive public support, and then we got to fix the outdated regulations.
Also, coal plants aren’t cheap. And coal has costs that are heavily subsidized by society. If you could calculate all of the external costs and level out subsidies, nuclear is cheaper and, more importantly, far far safer, than any GHG plant.
Sorry, but we’ve seen what happens when you build nuclear reactors in a low regulation environment under cost pressure.
It’s not pretty.
That’s what the industry wants to believe. Except that US regulators have shown a willingness to sign off on new nuclear power plants as long as you do all the paperwork right and show that you’re not some moron who will dump a pile of plutonium in the desert and run water over it to make steam.
Nuclear takes 5 years to build according to initial plans. That’s a joke, and everyone knows it. It’s going to take 10 years, and the budget will double over initial estimate, as well. That means it will take 10 years before you see a dime back on your investment, and it could all be for nothing if the funding shortfall can’t be made up. Some of this is regulations–you know, the kind that keeps another Chernobyl from happening–but a lot of it has been the fact that every plant takes boutique engineering and specialized labor.
The Westinghouse AP1000 design (what they used in Vogtle) was supposed to fix that boutique engineering. It did not. SMRs are also supposed to fix that boutique engineering, but their projects are also failing.
Meanwhile, you could invest your money into a solar or wind farm. It’ll start generating power in 6-12 months and start putting money back in your pocket. Nothing about the construction is particularly boutique; it’s almost all mass produced stuff. You don’t need specialists to put them together, either. There is a track record of solar and wind farms meeting construction deadlines and budget forecasts. Given all that, who the hell would invest money into nuclear?
Not to mention slow to build. Takes about a decade to get a nuclear plant going. If that is replacing coal, you are burning that coal during construction. The CO2 cost of that should be taken into account when comparing to much quicker renewables (approx 2 years). Also pouring all that concrete. Once it’s build, sure it’s green, but that is expensive, takes ages and comes with a big CO2 cost to get going.
Or you go renewable now, turn the filthy coal off about 8 years sooner and save a ton of money and CO2 right now.
