UK-based company was placed in administration in 2025
Ontario, Canada-based Nuclea Energy has entered into a definitive agreement with Moltex Energy Ltd – currently in administration – and its joint administrators to acquire advanced nuclear technology assets across its molten salt reactor and nuclear fuel recycling portfolio.
Moltex Energy Ltd, the UK-based parent company of MoltexFlex Limited and Moltex Energy Canada Inc, was placed in administration in 2025 after its directors failed to achieve the majority shareholder consent to new investments or the sale of its assets.
Nuclea Energy is developing the Morpheus microreactor, a lead-cooled, factory-built micro-modular reactor.
The target portfolio has been developed by Moltex over more than a decade, backed by over CAD96m ($68m, €59m) in funding from private investment, Canadian public programmes and the US Department of Energy, the company said in a news release.
The portfolio includes technology and development materials associated principally with Moltex’s Stable Salt Reactor–Wasteburner (SSR-W), an advanced molten salt fast reactor, and its next-generation Waste To Stable Salt (WATSS) spent nuclear fuel recycling process.
It also includes an extensive patent portfolio of 80 patents across nine patent families in advanced nuclear technology – including nuclear fuel, reactor, chemistry and materials – and nine pending patents on the fuel recycling process, Nuclea said.
