No, and no they don't subsidize commercial generation (at least outside
places like N Korea and the like).


They do both in the UK. Or they certainly did when Margaret Thatcher was still with us.

There is no reprocessing of commercial nuclear fuel at all in the US and
afaik, none currently going on anywhere world wide outside the few rogue
states that may be doing some.

Enrichment for weapons is a totally separate enterprise from commercial
nuclear power; it's a very inefficient way to do so so only those
needing to subvert other restrictions would go at it that way.


Like governments doing it secretly.

Sure, but he never said nuclear explosion, just explode.

Agreed, all I'm saying is they do go wrong.

But _NO_ commercial reactors have "exploded" from the fuel having had an
uncontrolled chain reaction.

Chernobyl was so destructive because the Russky's didn't build a
containment structure to save $$ and so the fire melted the housing
structure (essentially just a "Butler building") and thus let the smoke
plume disperse the gaseous and light fission products. But, it was a
conventional fire, not a nuclear explosion that was the event.

Would a nuclear explosion have been a lot worse? Twice as bad? 50
million times as bad? Would it be similar to a nuclear weapon? Or is
there a big difference in yield?

Of course it would have been, but it's pointless to speculate because
commercial reactor design is such that a supercritical mass required to
have a weapons-type reaction is simply physically impossible to occur.

What is the difficulty and the cause of reactor damage at TMI and
Fukushima is loss of effective core cooling and subsequent fuel cladding
failures or fuel melt. But, it's still not an uncontrolled nuclear
reaction event.

The most dangerous situation at TMI by far was making one's way thru the
crowd of reporters jamming cameras and microphones in your face on the
way to/from the gate at shift change...


Indeed. Reporters should be outlawed, poking their noses into
everything and making **** up.


Whooooosh !


Then make yourself more clear.

No, I'm just someone who, unlike you, knows his arse from a hole in

Yet you think a nuclear station has never gone wrong.

I have never said this.

I said "We do have nuclear power stations which can and do explode...."
You said "Wrong."


Only Fukushima exploded.


Ok not an explosion then, but a ****ing big release of nasty ****.


There have only been two that have done that, Chernobyl and Fukushima.
Both trivially avoidable but they were too stupid to do that.

but even I know many nuclear power stations have ****ed up.

Three is not "many".

You said never.

When?

Lemme see, 3 mile island

Where no one died or was injured. No external damage.

Chernobyl,

Where less than 100 died from the disaster.

So the radiation left won't hurt anyone or cause any costs or
problems?
You
really are an ignorant fool.

That's a different issue.

But still very significant.

that one in Japan....

Yeah, that one in Japan - for your information that was at Fukushima.
Where no one died and no one was injured.

Tell the Japanese it wasn't a problem. Why do you think it's ok if no
injuries or deaths occur?

Because it already tells us a lot.

So if my car crashed due to a fault and didn't hurt me, that would be ok
for me to have to pay out £1000s for repairs?

What about future cancers to those nearby?

Who says there will be any?

Everyone.


Wrong again, only some ignorant fools.

Nukes in fact put far less radiation into the
atmosphere than coal fired power stations.


But what about the spent fuel that cannot be disposed of without a 300
year sealed container?


Its reprocessed into new fuel when that makes economic sense.

What about the cost of rebuilding everything?

Rebuilding what? As it happens, the Fukushima plant was due to be
closed within 6 months of the incident anyway - end of life.

And no damage was caused by the reactors. All the damage was from the
tsunami, which caused some 25,000 deaths. Perhaps you should be
concerned about that.

What about the damage to wildlife?

What damage to wildlife?

Radiation will do that.


It didn't with Chernobyl or 3 mile island or Fukushima.


It's claimed sheep in Scotland were affected by Chernobyl.


Only in the sense that the increase radiation was measurable
for a short time so not a great idea to eat them for that time.
And Chernobyl was trivially avoidable. So was Fukushima.

And, for your information, you should look up "deaths from ordinary
industrial accidents", you'll find the numbers to be much larger.

Only if you take the numbers too literally like you do.

Why shouldn't I take them literally?

Because you're not taking into account other significant problems.


There are no other significant problems.


Cancer is a damn big problem.


But no evidence of any increase cancer rate and both
Chernobyl and Fukushima were trivially avoidable
anyway. The increased radiation levels around Fukushima
were no worse than Dartmoor sees all the time and hardly
anyone is actually stupid enough to avoid Dartmoor all the time.

And if your point is to say that nuclear power stations are a good
idea,
then I agree with you. But they are not completely safe.

Much, *much* safer than other forms of energy generation.

Agreed, all I'm saying is they do go wrong.


Everything does, even roads and buildings.


Agreed. What makes me laugh is greenies who say we must use wind power,
then the very same idiots say they don't want them scarring the landscape
and making a really really loud noise.


They arent that noisy. They do **** the appearance comprehensively.

Nope, the stuff used in bombs is made in specific purpose nukes.

It's why the governments subsidise them in the first place.


Why the govt paid for them, yep.

The biggest risk of something bad at TMI was, in fact, the potential of
a H2 explosion there but were able to get it vented without having such
an incident. With the tsunami at Fukushima, the ability to have hands
on site and take corrective action was too severely limited to be able
to have any timely mitigating actions.

Something in the power stations is required to make weapons. It may only be the first step I'm not sure, but the subsidies were for weapons, not "cheap" power. It's the same **** again now claiming solar is cheap. It's only cheap when the greenie subsidies come in.

a H2 explosion there but were able to get it vented without having such

In the case of Fukushima, repairs to what?

So you think no damage was caused? Do I really have to google it for
you?

What damage was directly caused by the Fukushima Nuclear Power
Station?

What about future cancers to those nearby?

Who says there will be any?

Everyone.

You mean over and above background?

Clearly.

So who says and how many. There again, it depends what we mean by
background. Most of the evacuated zone was less radioactive than
Dartmoor.

What about the damage to wildlife?

What damage to wildlife?

Radiation will do that.

As it has been doing since the dawn of time. You are perhaps unaware
that, every second, some 4,000 disintegrations of radioactive nuclei
take place in your body - and mine, and everyone else's. And the
body
has mechanism for repairing the damage, which are at work all day
every
day.

And the presence of these radioactive atoms has nothing to do with
nuclear power stations or bomb tests. Or Chernobyl.

Go into the restricted zone at Chernobyl without any protection then
report back.

We could ask the people who live there.
I will have to agree with Timmie that atomic energy is as safeas, or
safer than, most other forms of electrical energy production with a
few caviats.

When something DOES go wrong, the possibilities can be extreme.
There are several different competing technologies - and the SAFEST
one by a long shot is CANDU.
Disposal of spent fuel and safe shutdown and mothballing of reactors
MAY be a significantproblem in the future.

As far as Chernobyl and Fukishama, the effects of the leaked radiation
may never be fully known - but the FACT there will be detrimental
effects is known and accepted by anyone with hal;f a functioning brain
cell.

Radiation - man made or man influenced or not - is KNOWN to have
health issues - as basic as increased skin cancer from extreme
exposure to sun-light.

Anything that increased our exposure to harmfull radiation SHOULD be
of concern, but risks and benefits need to be assessed and balanced.

And many don't realise that coal fired power stations put
a lot more radiation into the atmosphere than nukes do
even than 3 mile island did.

Like I said - NUKES are as safe as, or safer than, most
"conventional" alternatives

The thorium content of fly-ash constitutes an "atomic waste" with
thorium and uranium levels in crops around coal plants up to 200 times
higher than around nuke stations


Until the nuke station goes wrong.


Even when it does, 3 mile island didn't do anything special when it did go
wrong.

What happened with Chernobyl and Fukushima is trivially
avoidable. Ensure that the stand by generators are well above
where any tsunami can get to in the case of Fukushima and
don't play silly buggers with the reactor in the case of Chernobyl.

Like I said - NUKES are as safe as, or safer than, most
"conventional" alternatives

The thorium content of fly-ash constitutes an "atomic waste" with
thorium and uranium levels in crops around coal plants up to 200 times
higher than around nuke stations


Until the nuke station goes wrong.


Even when it does, 3 mile island didn't do anything special when it did go
wrong.

What happened with Chernobyl and Fukushima is trivially
avoidable. Ensure that the stand by generators are well above
where any tsunami can get to in the case of Fukushima and
don't play silly buggers with the reactor in the case of Chernobyl.


All very well if everyone is a robot or sensible. But humans will **** up.

They do both in the UK.


Not anymore, and not for a long time now.

Or they certainly did when Margaret Thatcher was still with us.


Long time ago now.


I'm not that old am I?

There is no reprocessing of commercial nuclear fuel at all in the US and
afaik, none currently going on anywhere world wide outside the few rogue
states that may be doing some.

Enrichment for weapons is a totally separate enterprise from commercial
nuclear power; it's a very inefficient way to do so so only those
needing to subvert other restrictions would go at it that way.


Like governments doing it secretly.


Not many do.

Nope, the stuff used in bombs is made in specific purpose nukes.

It's why the governments subsidise them in the first place.


Why the govt paid for them, yep.


Something in the power stations is required to make weapons.


Its much better to have a nuke that only produces what
is used in nuke weapons, much more efficient. Power
generation nuke so produce some of the fissile material
used in weapons but dedicated nukes produce much
more of what you want much more quickly.

It may only be the first step I'm not sure, but the subsidies were for
weapons, not "cheap" power.


Not subsidys, the govt paid for the nukes.

It's the same **** again now claiming solar is cheap. It's only cheap
when the greenie subsidies come in.


That's not true anymore. Even with no subsidy at
all its now worth doing in places like Australia.
Not so much in places like that soggy little frigid
island where you get **** all out of them in winter.

The biggest risk of something bad at TMI was, in fact, the potential of
a H2 explosion there but were able to get it vented without having such
an incident. With the tsunami at Fukushima, the ability to have hands
on site and take corrective action was too severely limited to be able
to have any timely mitigating actions.

Radiation - man made or man influenced or not - is KNOWN to have

Anything that increased our exposure to harmfull radiation SHOULD be
of concern, but risks and benefits need to be assessed and balanced.

Well much as I agree it's not especially dangerous it IS an
uncontrolled nuclear reaction event.

The point being that reactors (Russian Chernobyl style RBMK excepted)
are designed to fail safely under core meltdown conditions. Wrecks the
reactor of course, but doesnt hurt people.

Even the RBMKs are now modified to be a lot safer. Though they do not
still have containment buildings.
