verstehen kann ich es auch nur schwer, der aktuellen globalen reaktorflotte fehlen ja schon ca 65mlbs/jahr
und durch overfeeding wird das defizit nur noch größter.
allerdings ist es von der kostenstruktur nur ein kleiner faktor, in bezug auf die erzeugte elektrische einheit/khw....

Electricity price
The €/kWh as the output of a power plant is based on the costs of initial investments, maintenance, fuel and waste treatment.In the case of a nuclear power plant, initial investments are quite big even though justified on an economical point of view. Indeed, loans are propitious (interests between 5% and 8%) and exploitation rate reaches 80%. The cost of nuclear kWh is way under the one of a classical power plant.
In addition, as the following figures can mention, kWh is almost insensible to the volatility of uranium price:
- 1. Fuel represents only 20% of the final cost of nuclear kWh.
- 2. Nuclear fuel is not directly used in forms. It has first to be converted and enriched in order to be exploited. Those supplementary costs are prominent in the final cost.

An increase of 50% in raw material would lead to a minor 5% variation as electricity output. In comparison, the very same increase for gas would have as consequence a 30% variation (cf. figure 4).
