Is it possible that similar thing could happen with uranium mining as Aberfan (You seem to have confused coal mining with the use of coal which although related are not the same) - why not? It's a mined product, so there's of course a possibility it could.

We don't actually have any uranium in this country that is actively mined so it's unlikely to happen in this country though.

As for burying it in boreholes then it's been looked at and it was deemed to be too expensive and no one could give any guarantees that it wouldn't cause problems (Presumably people who know more about it than you or I) - so again, to say that there is simply no problem as "It's totally sealed" is just not right.

Nuclear waste disposal: Why the case for deep boreholes is ... full of holes

A start-up in California wants to use directional drilling technology to put America’s spent nuclear fuel into deep boreholes. But such a solution won’t be cheaper, safer, or any less politically toxic than a mined storage facility.

They are comparing it to using mines which would obviously be cheaper.
As I have mentioned before the Boulby mine mine would be perfect and would take all of Britain's current and future waste
Some of the tunnels are more than 4,000 feet deep under the North Sea.
When the halite is removed the tunnels close back up due to the immense pressure sealing things permanently in solid rock.
How could that be a problem?
The mine is well up for it but nobody will give it considering due to prejudice and nothing more.

Robert Laybourne, managing director of Cleveland Potash, said to suggest otherwise was "gossip". He said: "It is total nonsense; ridiculous. There is no substance in it. The mine is not suitable for the storage of wastes, there is too much water about."

Nuclear waste disposal firm Nirex ruled out using the mine in 1988; but Mr Wennington says the stockpiles of plutonium waste have got to go somewhere

But yeah, just stick it down there….

I have been down there. Trust me no water in the deeper sections. Quite the opposite.
It was several of the managers I met who told me that it would be ideal and perfect for storing anything you want to vanish for ever.
There is also the salt mine in Cheshire which I have also been down. Again would perfect.
In fact Veolia are storing some low level waste down there already.

Just tell them then that you’ve been down there and it’s all ok - they’ll probably rethink their foolish decisions there and then

I am repeating what senior managers told me who have worked there for 20 years. I trust they knew what they were talking about. Not just Googling for answers.
It's all political - imagine their share price if people thought they were going to put nuclear waste down there. Of course they will deny it.
Imagine the protestors.
The science will never be allowed to win against prejudice.

Again - I’m sure they are very experienced at what they do but what experience do they have in dealing with nuclear waste? The quote above was from the md of the mine, but his view doesn’t count? You can choose to think that everyone is against nuclear because “ green” or you can choose to believe that the storage and disposal of waste might actually be more difficult than you might think.

Never mind the waste they know the geology of their mine better than anyone. If the tunnels close back up the way they described 3000 feet of solid rock below the North Sea will stop anything. Well apart from cosmic rays. They have a dark matter lab down there

 

[fizzy]

I will have to find the old pictures and videos I took down there. Truly fascinating trip. Made me very welcome.
Sadly I didn't see the dark matter lab though.

I think they may object to sticking radioactive waste in close proximity to them.

Wouldn't be.
Something like 600 miles of tunnels down there. The scale is incredible.

 

[fizzy]

Boulby is the deepest mine in Europe I think. 4000 feet.
Some South African gold mines go down 12000 feet
Got to be the safest place of all.

I applied (Accidently ) for a PhD to do with designing storage containers for deep borehole disposal, it's a research area, it isn't a viable solution yet. I think the fact that they wanted to pay three graduates for three and a half years, just to develop finite element models of these containers suggests there's a lot more to it than "drill a hole and drop it down". The chap who interviewed me has written literally dozens of papers just on the cements and grouts for backfilling and capping off the holes.

I can't find the article I read at the time now but IIRC if it went ahead it would take three years from starting drilling to having the hole full and capped off, and it would take two hundred holes to contain all the high level waste (Not sure if that's the UK's or the world's waste). It's only being considered for the highest level waste because there's too much medium and low level waste for it to ever work.

I agree.
Existing holes in the ground will always be cheaper.
Abandoned mines/tunnels have already served their purpose.

Heating oil is generally 28 second
Red / derv is 36 seconds . Correct me if wrong , so not a lot in it to adjust if you went over completely .

The Riello (and other) burner handbooks have jetting recommendations for 28 and 36sec fuels.
It's quite a common thing, having a shared bulk storage tank for farm diesel and heating.

I must admit I have never seen a rad with the thermostat at the top.

The race is on for affordable energy for the UK's homes and businesses

War in Ukraine has focused minds on how to get enough affordable energy for homes and businesses.

The chap up the road from me has TRV’s at the top , along with the pipe work feed at top entry and return at bottom
, on a sealed pumped system .

He spent some time loving abroad and said that is how they did and it’s “supposedly” more efficient .

I’ve seen top and tail pipe work here before on old pre TRV systems . But not like his .

It is the correct method, called cross flowed and puts the TRV head in a position it will actually get a reasonable reading of the air temp.

As the water cools flowing through the radiators it naturally wants to flow to the bottom so helps efficiency

Most people prefer the aesthetics of the TRV at low level
