England has " vast " underground caverns.  That were useful! ' before the " anti- coal " ,people shut them down .

What an ' opportunity ' to use those mines again,  Just to stuff them full of toxic waste. 

Stop subsidence & hide that waste for the next millennium or two.

Water permeates through the ground and comes out somewhere else.

 No one has found a good place yet. .  Nev

[Bruce Tuncks]

Why not in the arid zone of Australia nev? It seems to me that groundwater is almost non-existent there and the stuff you would place there is less long-term radioactive that what has been dug out at roxby.

 What in the great Artesian Basin?  AND you get DUST storms   Nev

Any ship in a navy is like a small town and with medical facilities to match (or better) so they need facilities to treat sailors and store the biological and hazardous wastes til their next friendly port visit.

 low level radioactive waste is produced in the day to day running of the subs and high level waste is collected when a reactor is decomissioned. nothing to do with medical waste.

what have dust storms got to do with anything.

Plutonium from atom bomb tests to start with. it's spread all over the desert from the British A bomb tests that was never cleaned up. The prevailing winds blew it to the eastern states.  Nev

but that has nothing to do with building a modern state of the art storage facility.

where do the uranium counterweights go when aircraft get scrapped.

Never seen then but they could be recycled. Do you mean depleted uranium?. I thought that was only used for armaments. Mallory Metal is used for balancing. You only need dense metals where there not much room.  LEAD is probably OK for most control balancing.  Nev

Or, given the shortcuts both mining companies and governments take, until next week.

 

I can't imagine that there will be much remediation in the Hunter just bloody big holes or the subsidence of Newcastle.

The UK’s North Sea wind farm project that was going to give power to every home in the country by2021 failed. The UK government reversed the law banning coal mining and is encouraging coal-fired plants to start up again, so probably too many miners around now to be dumping waste.

Mining company head offices? - Melbourne and Perth - sound like great places for toxic dumps!

At the moment live in the dead of Winter Coal is producing zero energy. Wind produces the most by far, approximately 48%, Gas 25% & Nuclear 14%. The UK was exporting quite a lot of renewable energy to Europe over the Summer. Coal fired power is only there as a backup and it takes a lot of time to fire it up to production capability. It is the dirtiest and heaviest emitter of all of the old technologies which is why it is being phased out. Same here.

on a show about scrapping jumbos they said there is a uranium weight in the tail but maybe i heard wrong.

[BrendAn]

Aircraft that contain depleted uranium trim weights for stabilizing wings and control surfaces (such as the Boeing 747–100) may contain between 652 and 1,059 pounds (296 and 480 kg) of DU. This application is controversial because the DU might enter the environment if the aircraft crashes.

Why would you be expecting serious coal-fired results now when Rishi Sunak only announced the reversal of bans on coal mining in June. There will be a reasonable lead time for the legislation to have been gazetted, people employed for mining, mines made safe, machinery brought up to working standard to produce coal, and a lead time for Coal-fired power stations  to also get their facilities into working order and emply operators. Coal- fired generation  doesn't take 40 years to come on line, but  it's still a long process.

That's the issue; well short of the 100% exepected if it was to power every house in the UK.

And " therein lies the crux of the matter" .

The stupid government,  got rid of the " teaching mines " so No more mining apprentices.

And Gas 25% - while still a source of CO2 gas is much more efficient and cleaner than coal - if nothing else, moving in the right direction.

Used to have an ex-Royal Flying Club of NSW PA-28-140 with depleted uranium aileron mass balances... DU was quite fashionable for a while!

[facthunter]

Lead is easy to shape. If there's room it will achieve the same result. Mass balance.  Certainly more practical for our type of flying machine. Depleted Uranium was used for armour piercing or penetrating deep underground.. Creates ongoing problems with pollution. Nev

So you don't believe it was used in aircraft even when your shown articles about it.

[facthunter]

I didn't SAY that BrendAn.  Back off a bit old mate.  Stick to facts. Nowhere in what you quote is there anything saying it wasn't used in aircraft.  Nev

[facthunter]

Mallory metal is used for crankshaft balance. It's hard and is pressed in to a carefully machined recess with an interference fit. The DU would be extremely hard and beyond our ability to work it and I don't know about the safety aspects of it at all. OR how you would purchase it.  Nev
