Dounreay Nuclear Power Site Available For Reuse In the Year 2333 (bbc.com) 76

Posted by BeauHD from the what-to-expect dept.
The site of a Scottish nuclear power facility should be available for other uses in 313 years' time, according to a new report. The BBC reports: Dounreay, near Thurso, was the UK site for the development of fast reactor research from 1955 to 1994. The facility on the north Caithness coast is in the process of being closed down, demolished and cleaned up. However, the Nuclear Decommissioning Authority said it would be 2333 before the 148-acre site is safe for reuse. The date forms part of the authority's newly-published draft strategy.

They said "credible options" for the site in future will be developed over the next two years. Buildings to be demolished include the distinctive dome-shaped Dounreay Fast Reactor (DFR). Important stages in the removal of radioactive material from the Prototype Fast Reactor (PFR) are expected to be competed over the next three years. A target date has also been set for the clean-up of a highly contaminated area called the Shaft. Waste is to be removed from the Shaft by 2029, according to the NDA report.

      My guess is that 75 years after firing up the first nuclear reactor, we aren't any closer to solving the problem of nuclear waste except for "put it far away and seal it". So in 313 years time, we won't be any closer. Apparently, the Weak Interaction does not only causes CP violations in Theoretical Physics, it also causes all hopes of containment to corrode long term as it corrodes all the materials we think of for sealing our containers.

        Containment is an interim solution. As the materials decay (and the radioactively 'hot' one decay pretty quickly), we run the byproducts through a reprocessing cycle. Before the barrels corrode. This removes a large quantity which is either not radioactive or has an extremely long half life. Which doesn't need to be contained. The hazardous remainder (now much smaller) is repackaged and stored until ts time for the next reprocessing cycle.

          Reprocessing does nothing in terms of amount of radioactivity yet to be released. It just tries to split the waste into different fractions, of which some are fissible. On the other hand, reprocessing contaminates new materials that haven't been radioactive before. Basically you have a trade-off: more radioactive material, but better sorted, and some of it can be used in new reactor rods.

          Alas, mining new uranium ore and processing that might get you cheaper fissible material, thus reprocessing is not too

    About 10 years ago I was on holiday in Scotland. Dounreay had already been dismantled but they had a visitor's centre open. We dropped in to look around and have a cup of tea. By the time I left, I was incredibly angry and convinced that nuclear power in it's current form is a really bad idea.

    I wasn't angry with the staff at the visitor's centre; I was angry with the people who'd worked at Dounreay in the past. It was primarily a research site. The research produced a certain amount of high level waste. Now they could have disposed of it in some sort of thoughtful manner but instead they used "The Hole".

    Dounreay is perched on a sea cliff. At some point, they'd drilled a shaft down to sea level and tunneled out to sea so they could get lots of nice cold sea water. The shaft is about 65m deep. They didn't need it any more so they blocked off the tunnel to the sea. Then someone thought, how about we just chuck stuff in this nice hole we have?

    They didn't keep any records of what went in. They didn't pack the material in any sort of fashion. They didn't stop the highly reactive metals from meeting the corrosive sea water. Eventually the hole filled up. What to do? The answer was to drop a massive concrete block on the stuff in the hole to compact it. That worked a treat. They threw more stuff in.

    One day the shaft blew up.

    So now, the clean up job consists of trying to remove mangled pieces of highly radioactive material from a 65m shaft without triggering another hydrogen explosion or creating a nuclear reaction. That's the job that going to take decades.

    So that's why I'm angry. There's nothing wrong with nuclear power itself. The problem is that you have pointy-haired managers and scientists who are dying of curiosity in charge of it. These people have to handle tons of material that must be accounted for with milligram precision. It's a recipe for disaster. If we can create nuclear reactors that don't need this level of care and attention then I'll be all for it.

    People are not calculating the long term costs to manage the waste and sites honestly when they compare prices for energy generation. In this day and age you are better off with solar and wind because as power storage gets cheaper you will wind up favoring those techs anyway. I'd rather gas peaker plants as short term solution while energy storage rolls in vs nuclear. The nuclear plants are expensive, slow to build, have tons of hidden costs, and cannot easily be exported or globall scaled up. They will be completely outdated by wind/solar and energy storage after only a few years online. If nuclear was much cheaper and faster to build it might be a slightly different story, but you're still mostly throwing money away by investing in a tech that hasn't improved significantly over many decades and isn't projected to improve much vs the competition of renewables and energy storage which have made HUGE gains in cost effectiveness and efficiency as well as are projected to continue to improve quite a lot in the next 20 years. That's all it comes down to. If you look 20 years ahead nuclear power looks like a dumb investment. Not an impossible dumb investment, but a waste of time and money that takes your nation and world in the wrong direction when the right direction is staring them directly in the face. Renewable and energy storage are pretty much booming all over the world right now and THAT is how you get things done, not with a tiny specialized industry that can only particually benefit from mass production and distribution like nuclear. Even just training even engineers and scientists to scale up solar to be solution to the future of energy would take a couple decades. It's a niche industry with only a few nations doing all the work and more importantly you don't want most nations managing nuclear reactors and waste anyway, even the rich and advanced nations can barely do it. If you have limited space in your country like Japan or the UK it's extra stupid! Many of the existing power plants have been built in poor locations on top of all that, plus the whole part where it scares people a lot more and rightfully so seeing how loose ground water contamination regulations really are and what are you going to do if you do poison a water supply.. clean it up... ? NOPE! You gonna wait a couple hundred years, that's a big yearly loss just try to save a couple bucks on nuclear power while renewables fully mature. I'd just go with the slightly more expensive renewable option which will drop in price and rise in efficiency and work with the future of energy generation better. That investment will pay off longer term in not only the products but also investing in the industry that has the clear path to the future. Also.. don't invest in diesel cars, it's a dead end! Stuff like this should be obvious by now, but millions of people still think nuclear has a shot.
