The 'issue' wasn't the number of deaths, it was the *total risk(s)* of nuclear versus (and only generally in comparisons with) other forms of electricity generation that I was talking about here. Yes. But what you overlook Here we go again with a left brainers perception of what 'I might overlook'. Are you really so thick / left brained that you might think I'd overlook such? is that the total number of deaths is a good measure of the riskiness of a technology. Of course? Which is why these figures are put forward for your consideration. But there aren't *relevant* re my point. Just because you have facts that state that to date, there have been no alien related deaths, doesn't go any way towards negating the fact that their could be (well, until we can accurately rule out the existence of any other species). There are loads of things out in the big wide world that are *very dangerous* and have to be handled very carefully. Only a complete idiot would deny their mere existence *could* post a large risk to us / the environment, a greater risk than if they didn't exist in the first place. The danger comes from the poor use of whatever it is. Yes ... with the key words there being 'the danger'. You have conceded the existence of such and so confirmed my point. The end. So enriched uranium and plutonium, f'rinstance, will be dangerous if you let the wrong people play with it. Or if you design a reactor which can be unsafe and don't train its operators properly. If OTOH you design it to be inherently safe, which is what happens these days, then you're much better off. 'Much better' not 'completely safe' I notice? It's not 'completely safe' because you are unable to guarantee that (of course). Chernobyl happend because of a poor design AND bad luck AND poorly trained operators. I know. Remove any one of these and the reactor operates safely. 'Safer'. But, so? Of course it "could" still be a problem. Quite. But with a good design and properly trained operators the risk is now very low, 'Of course', 'no question'. However, the 'point' is 'the risk' ... compared with say 'the risk' of a windmill falling over or a solar panel shorting out, (as far as the 'in use' risk is concerned). All of them will cause pollution and consume materials in their construction, nuclear probably more in it's decommissioning and loads more if stuff goes wrong). and I don't lose any sleep over it. Nor do I. Just as we "could" be hit by another 8-mile-diameter asteroid, but I don't lose any sleep over that, either. Nor do I, but not the point (... as far as I know, we aren't building / launching asteroids). You need to learn to assess risk. And you need to understand how to communicate with humans (or Vegans).

When our experts looked at the RBMK in the 1970's they decided it would not have been licensable in the UK presumably because of the lack of interlocks to prevent it being taken beyond the safe envelope. But as we have seen recently with the Max 8, safety system design can be cocked up too. No. It was not the lack of interlocks. It was the basic design of the reactor. It is nothing like Western reactors - part of it being designed to use hundreds and hundreds of small pipes, able to be welded by pretty well any old welder, instead of properly coded welders for the job. The design was known to a) increase power output as the control rods were inserted, b) take too long to insert the rods and c) a single failure could cause damage to nearby channels, defeating the concept of being safe with two failures (Western licensing would have required more anyway). Plus the Soviet Union did not even require any containment around the reactor. They knew it was unsafe, but did nothing about it. After Chernobyl, they did make some changes to improve safety - making the basic design safer. Changes that they could have done years earlier, but no-one dared to speak out against higher power. UK companies in the nuclear industry have a policy that anyone - no matter if they a Nuclear Safety Engineer or a humble labourer, can stop any job at any time if they think that there is danger ... even if that job is nothing to do with them, but they are just passing by and see something. Also, it wasn't an unauthorised test; but it had not been reviewed as carefully as it would have been in the UK. At the time it took place, it was not authorised at higher levels IIRC, only locally and the test began despite being far outside the parameters stated as required for the test and well into the danger zone - so it *was* unauthorised. As an example of the differences here. To change a single set-point requires access via a password or key protected control; which in turn requires documentation declaring what change is proposed, the reason for it, potential consequences, etc., which is then assessed by multiple disciplines onsite, in offsite design offices and possibly by the ONR to ascertain the effects of the change. Only then would it be authorised and actioned - with a full update of all the existing, relevant documentation. Then when changed, the change would need to be observed, checked and recorded. 60 years ago, things would have been different, but these days everything is *very* tightly controlled. |

Which is what is done with modern designs. Well of course "*anything* that pollutes somewhere in such a way that it can't be inhabited for a very long time" is not nuclear power. Christ on a bike they even dropped a nuke on Hiroshima, never 'cleaned it up' and people have been living there ever since with no ill effects. All this paranoia comes from the fact that (a) Fear of nuclear was a cold war weapon in is own right, and governments tacitly encouraged it - especially the Soviet Union, who were backing CND and the Labour party covertly. CND became the Greens to all intents and purposes after nuclear fear 'went away' (b) No one actually knew. The effects of total high single dose exposure were known, as were the effects of chronic medium dose exposure. Both caused cancers. There was no evidence whatsoever on the effects of chronic low dose exposure, and they needed some kind of metric. So they picked 'lifetime dose' as a metric. It was as wrong as saying that if drinking a gallon of vodka has a 50% chance of killing you, drinking a gallon of vodka over a lifetime has a 50% chance of killing you. (c) So they adopted the LNT model of total dosage as a metric for health and safety regulations. The power station companies said they could meet extremely low emissions regulations and did. (d) LNT was a gift to the greens, because it allowed them to model disasters from even minor spills of radioactivity and led to such statements as 'contaminated for thousands of years' 'no such thing as a safe dose ' 'that is what your *own government* says' . Out of LNT came all the predictions of MegaDeath post Chernobyl that simply never happened. My dear Vegan Green sister still believes that 'it was based on government models, therefore it was correct' and 'the government covered it up, because the government cannot be trusted' She thinks she is intelligent....but I digress. The fact is that huge areas of the earth have been contaminated for millions of years by ....sea water! You cant grow any crops foir vegans in the middle of the oceans! The total amount of long term radioactivity in the sea is also ****ing ginormous. 4 billion tonnes of 'nuclear waste' dissolved in it before we even built the first atomic bomb. Dartmoor is, according to the LNT model, 'uninhabitable' as is much of Cornwall. It is many times the radioactivity of FUKU exclusion zone or Pripyat near Chernobyl. https://www.world-nuclear.org/inform...h-effects.aspx is a good read if you *can* read Long Words and Do Simple Sums, so not suitable for T i m sadly. -- "First, find out who are the people you can not criticise.

These points only apply IF you drive it outside the envelope One of the impressions you get from Chernobyl is that the operators behaved the way they did because they felt they had a sure fire fail safe, scram, to shut down the reactor. It is slightly concerning to see the same over confidence in safety systems reflected in this thread. No, just confidence. Its only your complete lack of technical understandingÂ* plus your total desire to remain irrationallyÂ* scared of 'nuclear power' against all reason that spins that in your mind into 'overconfidence' I'm 100% pro nuclear fission, 100% pro research into breeder reactors. Pro SMR, would be also be happy with a massive reactor building program like happened in France. I'm even pro fission as opposed to fusion. Unfortunately I'm also familiar with the kind of political idiocy that infects big projects The western systems are probably safer and better run, but to quote Schiller:Â* "Against stupidity the gods themselves contend in vain."
