Nuclear and effect of Serre: GHG CO2 and EDF ...

The French nuclear produces greenhouse gases. Here is an article from the number 2 the Ecologist published in 2000.

This is to be completed by the figures and diagrams referred to on this subject (2 page): https://www.econologie.com/forums/comparatif ... t7776.html

Of which here is an "extract":

Here is a subject that escaped me during this summer ... 8)

To clarify
http://www.nirs.org/climate/background/ ... ar_ghg.pdf
uploaded on econo:
https://www.econologie.com/fichiers/par ... 8hxgnD.pdf
Summary(Translated from English)
This article includes 103 lifecycle studies of nuclear power plants in terms of GHG emissions, to compare all the latest and original work transparent.
[]
He believes that the CO2 emission range of a nuclear plant during its lifetime is between 1.4g CO2 / kWh to 288 CO2 g / kWh, the median value being 66g CO2 / kWh.

This is a beautiful study by Elsevier. The entire life cycle is described.

Thus, nuclear power typically rejects 70 g CO2 / kWh

Note that this value is probably below the current reality and certainly future. CO2 because the cost of decommissioning and waste management will be great, but also, the Uranium ores are less rich, and therefore require to move millions of tons of rock / additional land.

We will gradually lead to the final stage of any nuclear: a double CO2 pollution and radioactive waste.

Here is a summary diagram

Added my little comment on the electric heater (topical).

It is common to assume that the nuclear electric Joule heating is decarbonised. This is completely false.

For he must burn in 3 when the central Joule received in the house.

So, this is equivalent to x 3 70 210 = CO2 g / kWh Joule heating.

Either 20% of the emissions that would have been with a hydrocarbon (oil or gas) burned locally in the house : Idea:

We will say, "it's always better", I answer "with nuclear waste", and above all "do you know the technology of wood in the fireplace?" :P

And also as Maloche pointed out, the winter Joule heating has a carbon footprint than that of a mix 100% nuke because central peaks gas / oil / coal set off or not importing foreign GW all low-carbon.

In short, all of this is complex and given the financial stakes, it is the subject of an intense disinformation. :?

AAAABsolument! remu :D

By CO2 against the emission of gas and fuel oil are respectively:

What makes electricity France produces as much gas as CO2 !!
and yet it ignores all annexes energy expenditure

and not counting the fucking radio active waste

For other emissions:

and there are not as CO2 rejected for electricity production in France (for other countries it is worse)

It's pretty amazing ...

But this is due to the costly cycle of life of the fuel uranium ore to depleted U238, not to mention decommissioning and waste storage center construction.

In terms of heating, the only advantage of nuke compared to gas, is to have radioactive waste free. : Cheesy:

Too bad your doc doesn't say "nuclear 100%" : Idea:

Great about it :DThese documents are small gems, thank you for all that you post :)!

Hard to believe yes the first time : Shock: should absolutely disseminate this information across to everyone!

Officially, the CEA or SFEN announce 6g / kWh nuclear.

You see, just 10 times less than the likely reality. : Idea:

That said, it's less emissions than the hydrocarbon at large, but with the major drawback of radioactive waste and decommissioning.

Nuclear energy independence is a myth. All our uranium is imported from abroad.

The decoupling from oil to be qualified: when oil increases, the ore also, since it needs to be extracted, and that any increase in the area of ​​energy tends to affect other energy (law of supply / demand)

The renewable nature of nuclear power is widely advocated. This is an absolute lie since uranium ore will soon experience a "peak" (like oil), and it is a resource. fossil : Present on Earth for millions of years in finished inventory.

Voili here ... we could talk for hours. : Idea:
