France, and in general European wanted to close the fuel cycle. They wanted to allow multi recycling of the fuel. And I think that in France is today, the only country left where the recycling of nuclear fuel use the fuel is still done. If you're going to have a fast reactor, then the coolant of choices lead. That's the that's the logic there. We've led, you have, you can do completely passive safety systems as well. And, and we will show that you can do very cheap reactors.
