Exodys Energy
Recovering value from used nuclear fuel.
AJ2 is an angel investor in Exodys Energy. AJ2 is the investment vehicle of brothers Julien Lepleux and Adrien Lepleux.
What Exodys Energy is building
Exodys Energy is developing nuclear fuel recycling technology. Its UPCYCLE process is designed to turn spent fuel into domestic feedstock for the nuclear industry, helping close the fuel cycle for existing and next-generation reactors.
That places Exodys in a different part of the nuclear supply chain from companies building reactors. Its work concerns what happens to fuel after it has been used, and how material recovered from that fuel can be put to work again.
