Should the UK Re-Open An Old, Cracked Nuclear Reactor? (mirror.co.uk) 264

"Nuclear experts have warned against re-opening a 43-year-old Scottish nuclear reactor riddled with cracks over fears of a meltdown," writes the Daily Mirror.

An anonymous reader quotes their report: Hunterston B nuclear power plant was shut down last year after it was found that Reactor 3 had almost 400 cracks in it -- exceeding the operational limit. EDF, which own the plant in Ardrossan, Ayrshire, are pushing to return the reactor to service at the end of June and July and want to extend the operational limit of crack allowed from 350 to 700. However, the plans to reopen the plant have sparked fears it could lead to a nuclear meltdown similar to the 1986 Chernoybl disaster.

Experts have warned that in the very worst case the hot graphite core could become exposed to air and ignite leading to radioactive contamination and evacuation of a large area of Scotland's central belt -- including Glasgow and Edinburgh. According to Dr Ian Fairlie, an independent consultant on radioactivity in the environment, and Dr David Toke, Reader in Energy Policy at the University of Aberdeen, the two reactors definitely should not be restarted...

The plant, which is more than 40 years old, can generate enough electricity to power more than 1.7 million homes, and is one of Britain's eight nuclear plants which provide around 20 percent of the country's electricity.

Nuclear expert Professor Neil Hyat reminds The Sun that the reactor will be shut down by 2030 -- and "possibly earlier."

          The US will have the final say over what happens to the UK and its nuclear mil tech.
          All sites will clean and returned to an independent Scotland for Scotland to use in any way it wants.

            Support for Scotland joining the EU is way over blown. Realistically, it is none existent. Those that want to join the EU are the same ones that didn't want the UK to leave the EU. If you run a poll, not that they matter, with a independent Scotland of the UK then support drops to almost nothing, single digits anyway.

            So no, it is very doubtful that Scotland will join the EU if it gets it independence from the UK.

    1) The plant has been closed
    2) It's been closed due to structural reasons.
    3) The plant is 43 years old. Meaning the tech on it is 50-60 years old.

    Simply redefining the structural parameters on an obsolete reactor that's been sitting idle and turning it back on seems like not just asking, but begging, upon bended knee, for trouble.

      Agreed; Graphite reactors are Very old Tech.

      Wigner Energy and Wigner Growth are two problems no modern reactors have.

      The designs were obsolete in the 50's, even tho they kept being built.

      But they're great for making plutonium, which is probably one reason for bringing it back online.

          If you wanna make Plutonium, go with LFTR and simply scavenge it from the byproducts.

          The T in LFTR stands for Thorium. LFTRs don't make much if any Pu. They don't have U-238 in them by default (you could add it but its not there by necessity). They consume Pu if you use weapons grade Pu to kickstart the reactor but that's only one of many ways to kickstart a breeder. There are many reactors that are good at making Pu, the LFTR (or anything Thorium specific) isn't among them.

    Come on. Chernoybl was an unsafe reactor design and what made it so bad was that the thing literally disassembled itself due to the design and crazy stupid operator mistakes. THEN the whole thing caught fire, nuclear core and all, because it was made from flammable materials and couldn't be put out for days, killing many of the fire crew from radiation exposure. We are talking about a light water reactor, where the core isn't going to explode and catch fire, where meltdowns will take days, not seconds and the worst possible accident is much less dangerous and much less likely than Chernoybl's ever was.

    IMHO this article is blowing the risk out of reason and is invoking the name of the worst nuclear accident in history in an effort to sway public opinion and that has me suspecting they might not be interested in any rational discussion here. They just are agin' it, no reasoned argument, no facts are going to move them.

    IDK if this idea is a good one or not, but when some group starts to demagogue the issue with the likes of Chernoybl, I'm going to dismiss what they say as being about fear, not reality.

      It isn't a light water reactor. Both Hunterston B and Torness are AGRs (advanced gas reactors), which are a graphite-moderated, CO2-cooled design. It's safer in several ways than an LWR; it can passively cool through convection, for example, and it has a lower power density. However, if the blocks crack, and end up shifting around, that could be rather bad. If it blocks the control rods, or restricts the airflow in the fuel channels, it could cause problems. The cracking is a known phenomenon; one of m

  • I'm not a nuclear engineer so I was surprised to hear that the allowable number of cracks was not "zero".

    Given that the limit is not "zero" or "one", wouldn't the location of cracks relative to each other also be a critical (no pun intended) factor?

    • The same is true in bridges and things. Some cracks are expected. Each very small crack reduces the strength by some amount. The number is never zero, even when the concrete first dries there are some cracks.

  • Instead of putting band-aids on a creaky old reactor and risking disaster to squeeze a few more years of risky life out of it, why not just leave the old reactor mothballed, build a brand new reactor right next to it, and use the plant for another 40-60 years?

    It's not like the 2030 closure was holy writ dictated by some divine power... it was based on the assumption that the old reactor wouldn't be usable after that date. Build a brand new reactor, and the entire reason for closing the plant in 2030 goes aw

    • Put another way, does it make more sense to spend $500 million to rehab an old reactor and squeeze another 5-6 years of use out of it, while risking a horrific disaster near Scotland's two largest cities... or to spend $2-3 billion to build a new reactor next to the old one that's better and safer than the old one in every meaningful way, and good for at least 40-60 years of service?

      Humans in their wisdom, are just planning on doubling the number of allowable cracks. Much financially smart. Saves money. My guess is the limits will be increased until the reactor is exposed to air, and then the fun begins.

    • Yeh, they looked into that when "Hunterson A" was shutdown.

      Hinkley Point C is estimated somewhere around £19 billion and £21 billion at this point. However, as the only work done so far AFAIK is the pouring of the concrete platform that it will be built on, there is of course a chance that the cost estimates are wildly pessimistic and the whole thing will come in at a quarter of the price. And a tiny risk that it might end up more expensive than expected. On the upside you get 2 reactors for th

But a plant with 400+ cracks and nuclear engineers saying that it should not be extended, is a good reason to keep it down.
