How many nuclear power plant + to ride electric?

[Did67]

I repeat my sentence:

... this is associated to the feeling of security...

[I'm not fearful - the key on the door, on the outside I mean, all year round; does not prevent that the rare times when I crossed my end of forest by black night - there are black black ones! - well that's funny; this, every second lamppost, until a certain time ... yes ... simply, the "deposit" is not completely available, that's what I meant, far from it!]

[moinsdewatt]

.....
In any case, the rest of the gray energy contained in a liter of fuel is missing in this calculation, i.e. the energy it took to extract it, and above all transport it, refine it, retransport ... These figures vary enormously between the place of extraction and the quality of the deposit, but the enormous distances make that certain experts estimate, but I do not manage to find publishable links that that would represent 2 to 3 times the energy contained in one liter of fuel .......

The gray energy for the transport and refining of petroleum is quite low, of the order of 10 to 15%.

On the other hand, the gray energy for oil from the tar sands, or heavy oils from Venezuela (Orinoco belt), yes it becomes quite catastrophic.

[jonule]

That would be very disturbing to say that a car consuming to 5litres pump to 100km has actually consumed 15 liters ...

and the gray energy it takes for 1 kWh electric?
I'm talking about the extraction of uranium ore from Niger, the transportation then enrichment in fuel, the use even in power plant, then recycling (if we can use this term ..) and finally management in waste ?!
the number explodes then ... I will end up calculating it? =)
any energy to its gray energy anyway, if your PV produce on the spot, the used oil which I filter on the spot has then the best output! ...

In short, all energy consumed requires gray energy for the route, but it is however PAID by the consumer, for the benefit of the producer and the transporter ...

thank you Did67 for helping me;
"
1 EPR = a power of 1 MW, therefore 600 GW.
One year = 8 hours.
We will hope that brand new, this EPR runs at 90% (some technical stops).
So it will produce: 1,6 GW * 8 h * 760 = 0,9 GWh = 12 TWh
The consumption of a fleet of EVs, you started to calculate:
to 1.000.000 1.5 vehicles it makes TWh (billion kWh 1.5!)
In France, there is a fleet of 38 million vehicles.
So it will take about 1,5 TWh * 38 = 57 TWh
So it will take 57 / 12,6 EPR = 4,5 EPR which work 90% of the time.
"
therefore for 1 plant (4 to 5 EPR reactors) at 12.6 TWh, the default is 12.6 / 1.5 = 8.4 Million EVs
then the battery efficiency at 76%: only 6.384 million EVs are enough to add 1 such nuclear power plant:
well, that leaves room, while waiting to find solutions of production and energy saving ...

Finally until the solution is found, it goes straight into the wall anyway ...
I agree that the EV should be sold with its PV or other production subsidy?
which will not necessarily please EDF / RTE and is therefore by definition difficult to achieve!
end of the story ...

it remains to be seen how much surplus electricity is available at night, and the assumption that it has not been wasted until then but sold ...
it seems to me that it is the producer manager EDF / RTE who keeps these figures, a technical solution still used: the off-peak hour / full hour meter, in my opinion a specific "electric car" meter should emerge in front of an influx of consumption ...

thank you all for enlightening me!

There are periods when EDF straw neighboring countries to absorb our surplus nuclear production.
So put these kwh in EV batteries ...

[jonule]

certainly, but what are these periods? summer?
in any case, I understand better then why certain cities are so unnecessarily lit (commercial lighting) ...

In summer yes.
I also think that it is at night, since during the day there is more consumption.

Certainly !

But understand that these are sales on the so-called "spot" market (the bulk of trade is done on an organized market, with contracts).

Electricity is what poiubelles in the supermarket are.

Shocking. But insignificant in quantities! And very sporadic ...

So this cannot be a basis for a "general" reflection on systems ...

The major problem is that there is no trash in electricity: what is produced must be consumed the moment it is produced.
Otherwise it is the network that crashes, and especially the installations of individuals and businesses.

we could also say "then as much produce less kwh during the day"; =)
which would amount to lowering overall electricity consumption is also part of the discourse;
