France to cut nuclear power as rivers fail to cool plants

It's called a water cooling tower. Been around for decades.

Am I just wrong in my thinking here?

Those cooling towers are used where water is scarce to condense water for reuse. In places like Koeberg and even the now demolished coal fired powers stations at Table bay and Paarden Island where there was plenty of seawater for cooling, no cooling towers are required. Obviously, the French stations had enough water in the rivers to negate the building of cooling towers when they were designed.

Koeberg without cooling towers:

I worry that there are people in this thread who actually believe, and argue for, the cooling nonsense.

What is Bitumen? Bitumen is obtained by the partial distillation of crude petroleum. It is also called as mineral tar and is present in asphalt also. It contains 87% carbon, 11% hydrogen and 2% oxygen.

Thanks you mr Google. Put that in your pipe and smoke it.

tar is derived from coal, bitumen is derived from petroleum....
Americans use the term Asphalt (wrongfully), as asphalt is a mixture of bitumen and cement.

Fixed your assumptions. Now would you like me to mention yours other than:

Virologist and Covid specialist with an unregistered First Aid Certificate.
Covid expert with a chemistry book. (Unknown whether organic or inorganic chemistry)

Need more?

Pfft, anyone swimming at Melkbos can quarantee that water is still nice and cold. If you are lucky enough to hook a fish you pull it out frozen allready.

The tar issue. Yeah got the soft gummy feeling when in the high 30 even. Think they did alter the recipe slightly, but the main ingredient still does not like heat. Old roads seems to soften more than the newer one, but it is still there. That is in the cape Region, going out Durbanville.

I am pretty sure that when I built the bridges for the N1 bypass around Polokwane, the company I was with used SASOL additives for the asphalt, which were designed to make the road more robust to deal with higher temperatures.

That was 12 odd years ago, so a bit vague on the details, but I recall they were called something like SASOBIT and SASOFLEX.

I am more of a concrete guy, so wasn't directly involved with the asphalt, so I could be wrong.

No idea.
My point wasn't that Nuclear is better than coal. My point was that fossil fuels are finite and we need to be exploring renewables.
Continuing to advocate for the use of coal without planning for the inevitable end of its availability is short sighted.

The amount of coal in SA is far more than the general public thinks. Only the easily accessible coal has been mined near Witbank in Mpumalanga and Newcastle in KZN:

How much coal would you have to burn to give the same electricity as Koeberg?
monthly of yearly figures?
And how much Plutonium is used?
% kilo of plutonium vs 50 000 Tonnes of Coal?
What is the ratio?
Click to expand...
Uranium, you don't use plutonium for nuclear power plants, but one pellet of uranium is about 1 ton of coal in power, that one pellet is about 2.54cm squared.

I suggest the authorities tell the truth about why they are cutting nuclear power generation, not this kak cooling-story.

Have you ever looked at a news story and thought there wasn't actually a conspiracy involved?

A genocide, that's if you think the Yemenese are people.
Not to mention 4 by 4s for Al Queda and ISIS and being the prime suspects for giving the money for 9/11.

Uh, Nico, I know it's your pet subject but this is about cooling nuclear plants. Open your own off-topic for your pet subjects.

This is a blow to a company already €43 billion (R700 billion) in debt and needing to spend billions more in repairing reactors before it can get more revenue. It means the company may need massive state intervention to keep it afloat.

Sounds all to familiar... who is on the backend of this? my guess is those pushing for "renewable" projects...

Thanks.
With a 1000mw plant using 9000 tonnes per day, or 74kilogram of Uranium. Thanks Google
