I've touched on these points in a few ways in the past (e.g. testing of pressure vessels), but am more than happy enough to deal with more of them now.
Am I right in thinking that the power station where the pipe rupture was coal-fired rather than nuclear?
yes, but the ban applied to all power stations as I understand it, and the problems had it been a in the wrong part of a nuclear plant would have been many times worse.
Am I allowed to question how fair it is to bring up the '14 unspecified faults in Chinese nuclear plants' for the purposes you have, without cluing people into the wider context (global post-Fukushima desire to fix some things that were previously ignored) or the number and nature of faults detected in other countries? Or for that matter, the idea that governments were keen to find some relatively minor faults in order to create the perception that everyone was taking Fukushimas implications real seriously, getting stuff done, not being afraid to find faults.
you can bring up anything you want, it's just dishonest to ignore the post entirely as you'd done for an entire day.
I'd point out that virtually all the chinese plants were less than 10 years old, and the secrecy point where nobody outside the government knows what the defects are.
Are you in favour of nuclear power? Because at least one earlier post by you expressed sentiments about stuff needing to be 100%, no room for error with nuclear stuff. It really is bullshit to suggest that 100% quality situation exists or can ever exist in any country, whether we apply it to quality of components, testing and certification regimes, installation botches, design faults, maintenance regimes or training. It will be better in some countries and at some companies than others, and there is nothing wrong with exposing the worst offenders, but such acts really require you to get your facts straight from the offset, and care not to indulge in excessive boasts about the manufacturing prowess of our own nation. Especially given that our nation is associated with the complete mess made of the MOX fuel deal with Japan because of fraudulent certification issues.
I am not in favour of nuclear power, or nuclear submarines that Sheffield Forgemasters are also involved with, and I don't think I can let issues of employment for workers totally trump those concerns, I cannot support the positioning of the UK as a major supplier to the global nuclear power industry. That doesn't mean forgetting about the workers, it means this isn't the way I would choose to help them. Not that I believe me or any other single individual, with low stakes in direct matters such as how those workers earn a living, should ever get to determine the fate of such things.
no I'm not in favour of nuclear, however I am in favour of at least some level of joined up government thinking on the matter, so if we're definitely going to have new nuclear plants built then the government should support UK industry to gear up to supply as much of it as possible rather than just deciding to let the Chinese do the financing and supply of most of it.
I also do think there are serious questions to be asked about the reliability of the supply chain in China, based not on racism or patriotism, but on a build up of multiple stories of multiple related issues that have come out of China in recent years, along with an understanding of where those issues are likely to come from in a country that has rampant corruption issues, poor worker protection, poor environmental protection, poor regulation etc.
Obviously you'll never get to 100% perfection, but as a parallel, maybe have a think about why virtually all jet engines are manufactured by either Rolls Royce, GE or Pratt & Whitney, and why none of the major passenger plane manufacturers have ditched them in favour of the potential for cheaper Chinese manufactured alternatives. What applies to Jet engines should also be applied to Nuclear power plants IMO, the potential consequences of any failures are just to high to contemplate even slightly higher levels of risk of component failure.
I would agree that there are issues with UK regulation, and IMO these are getting rapidly worse as the standards of university teaching fall, regulators save money by not sending their inspectors on the industry leading CPD courses they used to all attend, inexperienced regulators take over from those retiring after overseeing decades of nuclear builds etc. A lot of which is down to both the neoliberalist thing of cutting regulation, and IMO to a degree the sort of anti-specialist sentiment you've expressed, that also is in vogue across government and politics to the point where DECC is headed by 4 economists (IIRC), and only has a single engineer on their entire management group, and very few engineers or scientist within the specialist departments, so they barely understand the stuff they're supposed to be deciding upon and regulating.
