Executives Comment on the Agreement
“This is a very exciting outcome for Moltex and an important recognition of the value created by our team, shareholders, partners and supporters over more than a decade. We were delighted by the level of interest generated through the competitive process. The timing could hardly be better: nuclear energy is experiencing extraordinary momentum globally, and used nuclear fuel is increasingly being recognized not simply as a waste liability, but as an enormous strategic energy resource. Nuclea provides a strong platform from which to build on what we have achieved and take these technologies into their next phase,” said Rory O’Sullivan, CEO of Moltex Energy.
“Nuclea sees considerable long-term potential in the technology and expertise developed by Moltex. The acquisition will add an important advanced reactor and nuclear fuel-cycle platform to Nuclea as we build a broader portfolio of technologies for the rapidly expanding nuclear market,” said Josef Freundorfer, CEO of Nuclea Energy.
Nuclea Energy’s Broader Nuclear Ambitions
The agreement comes as nuclear energy draws renewed government and private investment worldwide, with used nuclear fuel increasingly viewed as a resource rather than pure waste. For Nuclea Energy, the acquisition adds an established reactor design and fuel-recycling process to a nuclear technology portfolio it is building through separate deals.
