US advanced reactor company Oklo Sweden-based Blykalla have announced an expansion of their transatlantic partnership to broaden collaboration on fast reactor commercialisation.

Blykalla, which last year raised $50m (€43m) in capital to accelerate the industrialisation and commercialisation of its advanced lead-cooled reactor, the Sealer, aims to deploy capital and engineering resources in the US through the collaboration.

Resources include planned investments and expected personnel commitments on the scale of $100-$200m and 30-40 engineers, subject to final planning and approvals.
