The importance of low-carbon energy sources in efforts against rapid climate change makes nuclear energy part of a sustainable energy mix. While there is years of feedback on experience with water-cooled reactors, fundamental improvements can be achieved, particularly in intrinsic safety and reduction of nuclear waste production, using advanced nuclear designs. Heavy metal-cooled systems such as the lead fast reactor (LFR) combine the waste-reducing benefits of a fast reactor system with inherent safety-related properties such as high boiling point, chemical inertness and better heat transfer.

The ANSELMUS project aims to significantly contribute to the safety assessment of heavy liquid metal (HLM) systems, focusing on ALFRED and MYRRHA, which are included in the roadmap for the development of advanced systems in Europe.

Furthermore, the project involves an economic analysis that integrates the traditional discounted cash flow (DCF) methodology with the innovative mathematical framework of real options (RO) and stakeholder management.
