Unfortunately not captured. Again this depending of how to he nuclear plant has been engineered. Based on the ref below (in French) Up to 2000 kg can be released each year. https://www-boursorama-com.cdn.ampproject.org/c/s/www.boursorama.com/actualite-economique/actualites-amp/gaz-a-effet-de-serre-le-nucleaire-francais-emet-chaque-annee-1-3-a-2-tonnes-de-sf6-soit-l-equivalent-de-30-a-45-000-tonnes-de-co2-26dc6cfcec136b9947ca8c5f3d51397a https://www-boursorama-com.cdn.ampproject.org/c/s/www.bourso...

That's still peanuts compared to coal. Largest plant had 18 billion kgs of CO2 released last year. 2000 * 23,900 = 47.8 million kg of CO2 equivalent. Obviously the prior calculation also depends on plant size, etc.

  Réf wiki: According to the Intergovernmental Panel on Climate Change, SF 6 is the most potent greenhouse gas that has been evaluated, with a global warming potential of 23,900 times that of CO 2 when compared over a 100-year period.[37] Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years.

    Yes I saw that. Comment was comparing the CO2 emissions of the largest fossil fuel plant with a nuclear plant that releases 2000 KG of SF 6. If estimate the impact of SF 6 in terms of CO2 as 23,900 times the CO2 weight, than 2000 KG of SF 6 would be 2000 * 23900 = 47.8 million equivalent KG of CO2. Largest plant fossil fuel plant had emissions of 18 billion KG of CO2.

      I think you all have been trolled. Because SF6 is not exclusive to nuclear power generation. It is used in the transformer/switching station behind the turbines. To avoid arc lightning there. Which almost all other power generation is also using in the same way, like in almost all larger switching/substations also. It's the thing to use if you don't want to have arc lightning. So...in addition to all the CO2 some fossil fueled power plant emits, you have that, and the SF 6. Because behind the turbines they have the same halls with transformers and switching equipment.

        Thanks for the explanation. Glad to hear have some folks like you to providing additional for non expert like me.
